Abstract

The invention discloses an LED area light source which comprises a closed shell, a drive circuit board, a plurality of LED lamps and a transparent pouring sealant, wherein the closed shell forms an accommodating cavity; the drive circuit board is positioned in the accommodating cavity and is attached to the bottom of the closed shell; the LED lamps are arranged on the side, far away from the bottom of the closed shell, of the drive circuit board; the transparent pouring sealant is filled in the accommodating cavity and covers the drive circuit board and the LED lamps; the transparent pouring sealant is mixed with a light dispersing agent; and the light dispersing agent and the pouring sealant have different refractive indexes. The technical scheme provided by the invention can solve the problems that the existing side luminescence type panel light is low in luminescence energy efficiency and a straight luminescence type panel light is too large in thickness.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of lighting, and in particular to an LED surface light source. Background technique [0002] With the improvement of living standards, people's requirements for lighting are getting higher and higher. Especially in the field of indoor lighting, people prefer to use a light source with a large luminous area, uniform and soft light for lighting, so the panel light came into being. With the advancement of light emitting diode (Light Emitting Diode, LED) technology, the application of LED panel lights is becoming more and more common. [0003] Most of the existing LED panel lights use light guide plate technology, that is, the LED light source is located on the side frame of the panel light, and the light-emitting surface of the LED light source is at a 90-degree angle to the light-emitting surface of the lamp, so it is also called side-emitting technology. The light emitted by the LE...
