Abstract

The invention provides a low-cost LED lamp self-adaptation light adjusting control circuit which comprises a lower shell, an upper shell and an LED circuit board arranged in the upper shell. The lower shell and the upper shell are fixedly connected to form a lamp body. According to the low-cost LED lamp self-adaptation light adjusting control circuit, the light-emitting illumination range is wider, and the circuit has the beneficial effects of being simple in structure, relatively low in cost and durable, can be widely applied to various public places and is suitable for large-batch production and application.

Description

technical field [0001] The invention relates to an LED lighting fixture, which belongs to the lighting field. Background technique [0002] Compared with traditional gas fluorescent lighting, LED lighting has the advantages of high luminous efficiency, low radiation, low power consumption, long life, low driving voltage, fast start, environmental protection, shock resistance and pressure resistance, and miniaturization of lamps. Therefore, LED Lighting lamps have gradually replaced traditional gas fluorescent lighting. However, most of the LED lighting lamps currently on the market have the following problems: The distance between the position of the LED circuit board and the bottom of the lower housing is large, so that the irradiating range of the light is not wide enough. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems of the prior art, and provide a kind of LED circuit board on the lower case to place th...
