Dimmable LED lamp

Abstract

The invention provides a dimmable LED lamp comprising a lamp housing, a heating panel, LED light source modules and a transparent lampshade. The heating panel is arranged in the lamp housing, the LED light source modules are arranged on the heating panel, the transparent lampshade covers the lamp housing, the heating panel comprises a main heating panel and two side heating panels, the main heating panel is groove-shaped, the two side heating panels are hinged to two sides of the upper edge of the groove wall of the main heating panel respectively, and the LED light source modules are arranged on the groove bottom of the main heating panel and the upper surfaces of the two side heating panels. Light rays emitted by the LED light source modules arranged on the groove bottom of the main heating panel and the upper surfaces of the side heating panels are mixed prior to being transmitted through the transparent lampshade to form final emergent lamp of the lamp, and emergent light effect of the lamp can be adjusted by adjusting the rotation angle of the side heating panels relative to the main heating panel. Meanwhile, the height difference is formed between the light source module arranged on the groove bottom of the main heating panel and the LED light source modules arranged on the upper surfaces of the side heating panels, light rays projected onto the transparent lampshade complement dark regions of the LED light source modules, and effect of light uniformity is achieved.

Description

technical field [0001] The invention belongs to the technical field of lamps, in particular to a dimmable LED lamp. Background technique [0002] LED has the incomparable advantages of many traditional light sources, such as energy saving and high efficiency, high luminous rate, low power consumption, long service life, pure light color, high stability, strong safety, and environmental protection. It is a low-carbon, green and environmentally friendly lighting light source. Now many places have begun to popularize the use of LED lamps, but the LED light sources inside the existing LED lamps are fixedly installed, and the position and direction of the LED light source cannot be adjusted. This type of LED lamp cannot be applied to occasions where it is necessary to adjust the light output effect and provide various light distributions. [0003] In addition, LED lamps are also commonly used in low-slung spaces, such as ship aisles, cabins, and large-scale equipment operating ...

AI Technical Summary

Problems solved by technology

In the first method, because the LED lamp beads are arranged at intervals, the light is emitted to the outside world through the transparent lampshade. In this way, the light emitted by the lamp is not uniform, but alternately bright and dark, which affects the lighting effect.

The second method solves the problem of uneven light in the first method. However, the SMD LED lamp beads have low power and need to be electrically connected to each other in series. In this way, if one of the lamp beads burns out or breaks the circuit , it will cause all the lamp beads not to emit light normally. Moreover, due to the large number of lamp beads used in this method, especially for lamps that require high luminous intensity, the internal space of the lamp required is large, the manufacturing process is complicated, and the cost is low. high
