“Effective Projected Luminous Lens Area” (EPLLA) OUTPUT Analysis
This is a beautifully made LED Array using "Conal Reflectors", which are comparable in design to the "classy" designs that a few new Autos and SUVs use. However, you must realize that this design has only a maximum possible Effective Projected Luminous Lens Area (EPLLA) of 4.5 X 2.2 = 9.9 IN² -
≈4 more Cones and LEDs must be added
Here’s Wesbar’s® (Cequent®) latest LED 6/7 Function Light that nicely flaunts the best styling use of LEDs by using expensive "Conal Reflectors", which work well to increase EPLLA when more expensive, wider spectrum, higher powered LEDs can properly and completely light the entire Conal Reflector while projecting all its output within the Federally mandated 20° Left, 20° Right; 10° Up, 10° Down "Test Pattern".
This Array apparently produces a 3 X 4 = 12in² of "EPLLA" that would seemingly qualify for the 11-
Usually, after a few expansions and contractions, leaks occur in the best of sealed designs -
Also, we believe a pair of these Lights Retail for $100 and therefore, probably sell to OEs for $35 to $45 per pair
This Optronics® 3-
Bottom line … ≈ 4 more 3/4" Fresnels and LEDs are needed for Under 80" Vehicle use and ≈12 more 3/4" Lit Fresnels are needed for Over 80" Vehicle use.
