Led Writing Board production technical analysis

Led Writing Board production technical analysis：
With the packaging industry to downstream industry needs, in LED chip packages when installed directly, small volume, low cost, complete with Led Tablet

Not using separate optic lense, but in a package of the light source directly LED the wave optics lens design, use lens face masks to achieve the LED lighting optic lense function.

Look from the light distribution curve, to realize the above goal mainly is through the appropriate optical design to obtain bats airfoil distribution, thus obtained in pavement of rectangular appeares distribution. But ordinary high-power white LED encapsulation lens (i.e. a optics lens) is not suitable for application in LED directly on the clipboard, so in every high-power white LED to a optics lens on adding optic lense, “peanuts” type of optic lense can achieve good results.

Along with the progress of packaging technology, white LED by a single package 1W power leds devices to high-power integrated packaging light module. Current high-power integrated packaging light module of the maximum power 100W, but this kind of light more luminous area, because of the optical light distribution design problems.

Currently on the market, the message LED light source the main points in two ways: a single moksan 1W power white LED arrays and high-power integrated packaging light module. Although the national standard LED lamp, but not with the clipboard LED light source in the traditional reference standard road lighting should meet the following goals: appropriate average surface brightness, The total illumination high uniformity and vertical illuminance evenness, The right environment than, Glare control etc.
