Example Embodiment

[0015] 1 and 2, the LED surface light source of the present invention includes a housing 1, a base 2, an LED substrate 3, and a number of LEDs 4 mounted on the LED substrate. On the LED substrate 3, a phosphor plate surrounding the plurality of LEDs 4 is provided. The bracket 5, the phosphor plate bracket 5 has an inner cone-shaped reflective surface 6 that opens outward. The reflective surface 6 has a reflective material, which can be made by electroplating or coating. The phosphor plate bracket 5 is installed with a cover covering a number of LEDs 4 The phosphor plate 7 is spaced apart from the plurality of LEDs 4, and the phosphor plate 7 is coated with phosphor 8 on the side facing the plurality of LEDs 4.

[0016] In addition, it also includes the lamp holder, insulation layer, radiator, power supply, etc. of general lamps.

[0017] The LED substrate 3 is fixed on the housing 1 by a heat-conducting material. The phosphor plate 7 can be made of glass, PC, PMMA or other materia...

Abstract

The LED area light source includes one LED base board with installed LED's; one bracket around the LED's with one outwards opened inner cone type reflector coated with reflecting material; and one fluorescent powder board on the bracket to cover the LED's in some interval. The fluorescent powder board is made of transparent material and has fluorescent powder coated in the side facing the LED's. The LED base board made of heat conducting material is fixed on the casing via heat conducting material. The present invention forms homogeneous light emitting area in the fluorescent powder board, emits homogeneous gentle light, and can reach the functions of protecting eyesight and eliminating point light source.

Description

technical field [0001] The invention relates to a lighting fixture and a light source, in particular to an LED surface light source. Background technique [0002] Most of the existing LED lamps and light sources on the market are point light sources, which are prone to dazzling glare. Watching for a long time will cause fatigue and even cause vision loss; [0003] Secondly, the phosphor powder of the LED point light source is directly in contact with the LED chip and the substrate. Affected by high temperature, the phosphor powder is prone to aging, discoloration and volatilization, which affects the luminous intensity and service life. Control the amount well, so it is easy to increase the color deviation. In addition, the luminous effect of the point light source is not conducive to the appearance of the product. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an LED surface light source, which can avoid glar...
