Description

technical field

[0001] The invention relates to a semiconductor lighting device, in particular to a three-dimensional (3D) heat dissipation modular high-power LED lighting device. For home, office, shopping mall, road, tunnel, stage and other lighting. Background technique

[0002] Existing high-power (also known as power type) LED single tubes cannot be used alone, and must be equipped with heat dissipation devices and good heat dissipation conditions to ensure that the LEDs work at normal operating temperatures. A high-power LED lighting fixture usually has several or even hundreds of high-power LED single tubes, and each high-power LED single tube has one or more LED chips. Thermally connected with the radiator, the large amount of heat generated by the LED is dissipated through the radiator. As a semiconductor device, LED is very sensitive to temperature. High temperature will greatly damage the luminous efficiency, service life, reliability and failure rate of LED. T...
