New description: [New technical field] The utility model relates to a lighting fixture, in particular to an LED lamp with high uniformity of illumination brightness. [Prior Art] A conventional incandescent lamp is an electric light source that energizes a filament to an incandescent state and emits visible light using thermal radiation. Traditional incandescent lamps have become more and more popular due to their high energy consumption, large heat dissipation and short life span. The widespread use of LED lamps has gradually become a trend. LED light-emitting diodes are solid-state semiconductor devices that convert electricity directly into light. LED light-emitting diodes have many advantages such as low energy consumption, no pollution, no radiation, small volume, high temperature and long life. They are recognized by the world as green light sources. Governments are encouraged to develop LED technology to save energy. There is a problem of uniformity of illumination brightness in the transmission of cold weather, such as refrigerator lighting. Although the angle of the fluorescent tube is large, it will cause insufficient brightness in the middle of the refrigerator, and the brightness on both sides will be high, resulting in poor overall uniformity. [New content] The utility model overcomes the shortage of high uniformity LED lamps in the prior art. In order to achieve the above objectives, an LED lamp, including earning provides a kind of illumination brightness, adopts the following technical solutions:
