High heat radiation performance LED lighting unit and light distribution-adjustable light fitting using the same

Abstract

The invention relates to an LED lighting unit with high thermal diffusivity and an adjustable light distribution light fitting applying the lighting unit. The invention relates the LED lighting unit which comprises a lamp body, an LED light source, an LED drive circuit board, a light transmission housing plate, a cover plate of the lamp body and end covers at the two sides of the lamp body; wherein, a plurality of LED light sources are arranged in the lamp body in array, the LED drive circuit board is arranged in the lamp body which is also provided with a plurality of rows of lattice-shaped heat conducting reinforcing rods that can effectively educe the LED light sources and the heat generated by the drive circuit board, and a revolving joint is arranged outside the end covers at the two sides of the lamp body; the adjustable light distribution light fitting comprises a mounting rack which is provided with a device that is fixedly connected a carrier and a device that is connected with the revolving joint of the LED lighting unit with high thermal diffusivity in an adjustable way. The LED lighting unit can ensure the service performance and the service life of the light fitting, improves the production efficiency and meets the requirements for distribution light in most of the time. The adjustable light distribution light fitting has convenient assembly, good universality, high installation efficiency, convenient maintenance and adjustable lighting angle.

Description

technical field [0001] The invention relates to an LED lighting fixture, in particular to an LED lighting unit that can be assembled and installed and has high heat dissipation, and an adjustable light fixture using the unit. Background technique [0002] In 1965, the world's first commercial light-emitting diode (LED) was born, and after more than ten years of development, it has developed rapidly in the field of display technology; the major technological breakthroughs in the early 1980s made LED enter the field of lighting technology for the first time; From 1991 to 2001, further developments in material technology, chip size and shape increased the luminous flux of commercial LEDs by nearly 30 times; in the late 1990s, LEDs that produced white light were first developed by exciting YAG phosphors with blue light; With the continuous advancement of technology, the development of white LEDs is quite rapid in recent years. The luminous efficiency of white LEDs greatly exceed...

AI Technical Summary

Problems solved by technology

This method solves the heat dissipation problem to a certain extent, but because of multiple indirect heat dissipation, the effect is limited. At the same time, it is limited by the shape and size of the heat-conducting substrate when applied to different lamps, and does not significantly improve the cost and processing efficiency.
