The lighting fixture and associated retrofit kit offers a device with great versatility and simplicity of installation. The availability of a substantially flat LED panel having edge lighting makes it possible for thin panels of flexible length and width delivering uniform light output.
Edge-lit LED panels are becoming an extremely popular technology used in indoor lighting fixtures. Current LED flat panel lights are typically designed by using edge-lit backlight theorem, light is transmitted from an LED array to a central area of an edge-lit panel through light guides. The introduction of the edge-lit LED panel lights is based on balancing the relationships of the aforementioned factors to achieve a fixture that produces a light output that appears consistent to the human eye across the diffuser panel. the strongest light output intensity area) will be observed. For a direct-lit light panel having the diffuser layer disposed too near the LED light sources, the light output is non-uniform and hot spots (i.e. As a result it creates a point source of light which can be uncomfortable or harmful to a person's eyes. LEDs are oriented directly toward light diffusing layer, inducing the light emitted from LEDs to shine directly onto light diffusing layer. But bear in mind, LED is a form of directional light source of which light output intensity of the Lambertian lights is strongest at 90 degrees. A direct-lit LED panel comprises a plurality of LED light sources which are directly disposed under a panel. Two of the primary lighting panel structures are direct-lit backlight modules and edge-lit modules. An LED panel light is designed to provide sufficient lighting to replace the current fluorescent fixtures of varied light intensity, or lux level. Suspended ceiling represent a large proportion of the commercial, office and retail space.
LED flat panel light is an innovative lighting product in recent years. Light emitting diodes (LEDs) are getting more commonplace in general illumination applications, such as office spaces and conference rooms.
