AOptical Design:We have a lot of experience in imaging and non-imaging optical design. Especially in the LED lighting lens, we can simulate the final result which is near the real injected lens. We have patent structure to ensure the minimum chromatic deviation.
Mold Design & Manufacturing:We design the mold with considering the mold flow and form compensation skills. That means we can deliver the product in a short time without modifying the mold for n times.
Plastic Injection:All our plastic lens are injected from Fanuc optical grade injection machine which produce stable and precision optical lens. Our operating engineers have ample experience in complicated structure of optical plastic injection.
Design capability of using(PC:UL94V-0)
PC:Capable of passing UL 94 V0 grade to have better flame resistance, but absorb the light passing through it.PMMA:No light absorption lead to higher transmittance, but very bad flame resistance.We use the PC with UL94 V0 grade to make lens which has nearly the same high output performance as using PMMA.
Lower Chromatic Aberration
The phosphor on the LED can change the light to different color. But the light path difference that light pass through the phosphor will induce color shadings.
With the lens to converge the light will lead to more heavier color shading.
We have patent structure on the lens to make smaller color shading . -

TIR 是少数的特殊物理现象,可以将光线百分百的反射而无损耗。
镀膜反射杯受限于膜层的反射率而有损耗; TIR 设计不须有任何镀膜; 镀膜反射层的耐候性与寿命较不稳定。 -

光线由空气进入水中后,较快介质入射光速较慢介质时,折射线会偏向法线→入射角>折射角 入射角大于临界角达到全反射 -

光学原理
A- 光强度I坎德拉坎德拉(cd)cd = lm / sr
- 光通量φ流明Lumen(lm)lm =瓦特
- 光照度E勒克斯勒克斯(lx)lux = lm / m2
光通量(luminous flus)光源所发射出来的光线数量,如同水流一般,每秒的水流量,单位为流明(lm)
2.光强度(发光强度)是光源在单位立体角内的水流,以I表示,单位为坎德拉(candela,简称cd)。
3.光照度(照度)是从光源照射到单位面积上的光通量,以ë表示,照度的单位为勒克斯(勒克斯,简称LX)。
