Problems solved by technology

Both have good light-gathering performance, but their light-gathering efficiency is low, generally 70-75%. In order to improve the light-gathering efficiency, both the reflector and the total reflection condenser lens need a larger volume, thus increasing the The volume of the lamp; at the same time, the mirror surface and the total reflection surface of the reflector are easily polluted, reducing the reflection efficiency
But because its illuminating device is connected by a connecting device, constitutes the whole structure, after illuminating device is assembled, can't arbitrarily change, if have LED damage to need to replace, assemble and disassemble and maintenance trouble; Suspended and fixed to work in a 3D heat dissipation environment, but the middle radiator still has the problem of poor heat dissipation because there is no air circulation channel in the vertical direction of the lamp body

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...
