Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] figure 1 It is a three-dimensional exploded view of the LED lamp according to the first embodiment of the present invention. The LED lamp 100 includes a lamp body 20, a bulb case 10, a plurality of LED light sources 50, and a light distribution member 40. These LED light sources 50 are arranged on the top of the lamp body 20. On the other hand, the bulb housing 10 is covered on the top of the lamp body 20 to accommodate the LED light sources 50 .

[0015] Please refer to figure 1 and figure 2 , these LED light sources 50 are arranged in a circular shape around the center of the top surface of the lamp body 20 , and the light distribution member 40 is arranged above these LED light sources 50 . The light distribution element 40 includes a light emitting portion 41 and a reflective portion 42 , and the light emitting portion ...

Abstract

The invention relates to an LED (Light Emitting Diode) lamp, which comprises a lamp cap body, a bulb shell, an LED light source and a light distribution member, wherein the LED light source is arranged on the top surface of the lamp cap body, and the bulb shell is arranged at the top end of the lamp cap body to accommodate the LED light source; the light distribution member is arranged above the LED light source, and comprises a light emitting part and a reflecting part, and the light emitting part is arranged on the reflecting part; the reflecting part is of an inverted frustoconical shell structure, and the outer side wall of the reflecting part is a reflecting surface; a through hole is formed in the middle of the reflecting part, and the light emitting part is made of a transparent or translucent material and projects towards the direction away from the reflecting part; the light emitting part is arranged opposite the through hole of the reflecting part, and the reflecting surface of the reflecting part is used for reflecting light emitted by the LED light source to the bottom of the bulb shell. The LED lamp has the advantages of simple structure and uniform light distribution.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an LED lamp. Background technique [0002] In recent years, due to the rapid development of the LED industry, LED lamps have gradually replaced traditional lighting fixtures, and LED chips have been rapidly developed as light sources in the field of indoor lighting. People are constantly exploring a way to overcome the problem of small LED light distribution angles. However, if the current LED lighting fixtures meet the requirement of large-angle light emission, the structure is often complicated, and the light distribution is very uneven. In order to make LED lamps replace incandescent lamps, it is necessary to overcome the problems of small lighting angle and uneven lighting of LEDs. At present, the usual technical method is to set the LED light source on a three-dimensional bracket, and install the bracket on the top of the lamp head, so that the LED light source is vertically arr...
