About 'led replacement lamps'|Cree shows off 'no-compromise' LED replacement for 60-watt incandescent bulbs








In               the               mid               '90s               they               took               a               quantum               leap               to               replacing               our               (approximately)               100               Watt               incandescent               lamps               in               our               traffic               control               units               at               most               of               our               intersection               locations               through               the               country.

They               replaced               the               lamps               along               with               their               colored               filters               (in               some               cases)               with               Red,               Amber               and               Green               LED               lamp               clusters.

The               Initial               Applications               of               LEDs
               Our               traffic               lighting               systems               are               now               littered               with               retrofitted               original               incandescent               lamp               assemblies,               now               using               the               much               more               visible               LED               lamp               cluster               assemblies......and               I               must               say               saving               our               municipalities               and               towns               an               estimated               90               %               on               electrical               consumption               of               the               incandescent               originals               and               as               much               as               97               %               when               a               single               Red               turn               arrow               is               replaced               with               an               LED               arrow               cluster.

This               becomes               a               direct               electrical               savings               on               those               municipalities               and               of               course..

the               people               who               have               to               pay               the               taxes               to               run               them.

What               this               really               tells               us               is               that               before               the               LED               replacement               of               the               original               incandescent               lamps,               we               were               paying               100               %               of               the               electrical               costs               to               run               the               traffic               lighting               system,               but               only               receiving               10               %               of               the               useful               lighting               value.

The               other               90               %               was               being               released               as               heat.

WOW               !
               Initially,               some               of               the               town               policy               makers               were               reluctant               to               adopt               the               simple,               though               very               noticable               change               to               the               new               technology,               but               once               they               were               made               aware               of               the               savings               from               lower               electric               costs               along               with               their               much               greater               reliability               and               virtually               zero               maintenance               costs...they               were               sold               on               the               idea.
               This               phenomenum               has               not               only               transpired               here               in               the               U.S.,               but               also               throughout               the               world,               with               some               of               the               bigger               tranpirations               in               Japan...because               of               their               greater               need               to               conserve               energy.

It               is               hoped               that               this               positive               change               continues,               especially               with               the               global               trend               toward               energy               conservation.
               Many               Other               Uses               Have               Now               Sprouted               And               Benefited
               Mines,               or               that               similar               type               of               environment               where               power               is               difficult               to               provide               is               where               rechargable               battery               power               can               be               used               because               of               the               high               efficiency               of               the               LED               lighting               technology.

Using               LEDs               in               this               type               application               also               offers               greater               protection               than               other               types               of               lighting               such               as               incandescent               since               LEDs               do               not               shatter,               revealing               a               white               hot               filament,               thus               possibly               causing               ignition               of               volatile               gases               along               with               its               consequences.
               Today,               many               areas               of               the               under-developed               world               are               finding               the               ideal               use               of               the               unique               qualities               of               the               LED.

Some               areas               of               Africa               as               well               as               many               remote               villages               of               India               are               quickly               replacing               the               long               time               use               of               the               oil               lamp               with               the               LED               lamp               and               are               now               also               using               the               latest               in               recent               Solar               panel               technology               to               recharge               the               battery(s)               during               the               daytime,               achieving               an               almost               "perpetual"               night               lamp,               or               reading               lamp.

The               cost               of               the               simple               electronics               to               accomplish               this               is               very               little               and               it               replaces               all               the               lamp               oil,               lamps               and               the               ever-present               fire               danger               and               air               polution               from               their               use.

Just               to               think               of               the               labor               savings               involved               from               the               need               to               procure,               store               and               refill               the               lamps               on               a               regular               basis               is               enough               to               warrant               a               great               sense               of               satisfaction               from               the               implementation               of               this               new               lighting               technology               and               its               application               of               Renewable               Energy.

    Holiday               lights               are               a               tradition               for               many               people,               but               the               cost               can               be               hard               to               justify               these               days.

    Plus,               the               usual               incandescent               lights               can               be               high               on               maintenance.

    They               can               short               out               easily,               or               the               bulbs               can               burn               out               on               their               own,               and               sometimes               cause               other               bulbs               to               go               dark               as               well.

    Now               there's               another               option:               LED               (light-emitting               diode)               lights.

    They're               easier               to               maintain,               cheaper               to               use,               and               safer,               too.
                   A               brief               description               
                   Standard               incandescent               bulbs,               of               any               size,               produce               light               by               heating               a               filament;               when               the               bulb               "burns               out,"               it's               because               the               heat               has               finally               broken               the               filament.

    LEDs,               on               the               other               hand,               use               electrons               moving               in               a               semiconductor               field.
                   LEDs               have               actually               been               around               for               a               long               time.

    One               of               their               earliest               uses               was               in               digital               clocks.

    But               now               they're               being               developed               for               many               more               applications               -               one               of               which               is               holiday               lighting.
                   Advantages               of               LED               holiday               lights               
                   Unlike               incandescent               bulbs,               LEDs               aren't               made               of               glass,               so               they               can't               shatter.

    They're               safer               for               other               reasons,               too.

    They're               resistant               to               electrical               shocks.

    And               they               don't               produce               heat,               so               they               won't               cause               burns               if               they're               handled               when               they're               lit.

    The               lack               of               heat               also               makes               them               much               less               likely               to               start               a               fire.
                   LED               bulbs               rarely               burn               out,               and               even               when               they               do,               the               other               bulbs               stay               lit.

    You'll               need               to               replace               only               the               burned-out               bulb,               and               that               one               will               be               easy               to               locate.
                   This               brings               up               one               of               the               biggest               selling               points               of               LED               lights               -               their               longevity.

    They               can               last               up               to               100,000               hours,               which               experts               estimate               to               be               about               11               seasons'               worth               of               light.

    How               often               do               you               have               to               replace               your               incandescent               lights?
                   Longer-lasting               lights               also               cost               less,               because               you               don't               have               to               replace               them               as               often.

    But               there's               another               reason               why               LED               lights               are               cheaper               -               they're               much               more               energy-efficient               than               incandescents.
                   A               large               incandescent               bulb               on               a               string               of               holiday               lights               uses               7               watts               of               electricity.

    That               may               not               sound               like               much,               but               compare               it               to               a               mini-bulb,               which               uses               just               0.45               watts.

    Sounds               better,               doesn't               it?
                   Now               check               out               LED               lights.

    Each               LED               bulb               uses               only               0.043               watts.

    That's               one-tenth               the               usage               of               a               mini-incandescent,               and               less               than               a               hundredth               of               what               a               large               incandescent               bulb               uses.
                   Cost               issues               
                   If               these               figures               seem               a               bit               obscure,               consider               the               effect               in               dollars.

    The               estimated               cost               for               burning               a               string               of               300               large               incandescent               bulbs               five               hours               a               day               for               45               days               is               $76.

    For               a               string               of               mini               incandescents,               that               amount               drops               to               $5.

    But               for               a               string               of               LEDs,               it's               less               than               $.50.

    That's               right               -               50               cents.
                   LED               lights               do               cost               a               bit               more               to               purchase;               mini               incandescents               are               very               inexpensive               these               days.

    But               if               you're               planning               on               using               holiday               lights               for               many               years               to               come,               you'll               save               money               in               the               long               run.

    You'll               probably               have               to               replace               those               minis               several               times               -               some               of               the               cheaper               sets               last               only               a               year               or               two               -               in               the               time               you'll               have               the               LEDs.
                   Availability               
                   LEDs               can               be               a               bit               hard               to               find,               especially               late               in               the               Christmas               season.

    That               will               change,               though,               as               they               become               more               popular.

    And               increased               availability               will               probably               bring               the               price               down.
                   Even               if               you               can't               find               LED               lights               this               year,               it's               worth               looking               for               them               next               year.

    They'll               save               you               money               as               well               as               saving               resources               for               the               future.
