LED flat panel light is an innovative lighting product in recent years. However, current flat panel light products still contain some drawbacks, such as narrow lighting areas and hot spots. In this study, a micro-secondary lens array technique was proposed and applied for the design of the light guide surface to improve the illumination uniformity. By using the micro-secondary lens array, the candela distribution of the LED flat panel light can be adjusted to similar to batwing distribution to improve the illumination uniformity. The experimental results show that the enhancement of the floor illumination uniformity is about 61%, and that of the wall illumination uniformity is about 20.5%.
Goldsuno is by far offering the biggest variety of led square panel light sizes, so you should be able to find the fixture to fit your existing grid ceiling. The best part about these is that they are an incredibly thin half inch in height, so you will barely even notice that these panels are not recessed. That also allows you to mount them under cabinets for great kitchen counter light or on the wall to give contrast to the room.
If you want to buy led panel light or other led flat panel light fixture, Goldsuno can meet your requirements.
