Abstract

An LED lamp comprises a light transmissive lamp cover (60), a heat-dissipation submount (63), LED light-emitting units, a layout circuit conductive layer used for electrically connecting the LED light-emitting units, and a fixing mechanism used for fixing the lamp at a set position. The LED light-emitting units are fixed on the heat-dissipation submount (63). The light transmissive lamp cover (60) and the heat-dissipation submount (63) are mounted together to form an accommodation cavity for accommodating the LED light-emitting units. The fixing mechanism is directly fixed on the heat-dissipation submount (63), or formed integrally with the heat-dissipation submount (63), or directly fixed on the light transmissive lamp cover (60), or formed integrally with the light transmissive lamp cover (60). Heat-dissipation through holes (67) are arranged between the LED light-emitting units, and match the arrangement of the LED light-emitting units. Each LED light-emitting unit is adjacent to a heat-dissipation through hole (67), the heat-dissipation through hole (67) penetrates through the light transmissive lamp cover (60) and the heat-dissipation submount (63), and both ends of the heat-dissipation through hole (67) are in communication with the external air to form a convective air heat dissipation channel. The LED lamp has a simple structure and good heat dissipation effect, and the LED light-emitting units thereof have a long service life.

Description

Technical field [0001] The present invention relates to an LED lamp for lighting, in particular to an LED spotlight, LED ceiling lamp, LED ceiling lamp, LED tube, LED bulb, LED street lamp, LED table lamp, LED tunnel lamp and the like. Background technique [0002] Compared with traditional light sources, LED light-emitting diodes are free of lead and mercury, no flicker, energy saving and environmental protection, long service life, fast response speed, vibration resistance, easy maintenance, high brightness, low energy consumption, no ultraviolet radiation and environmental pollution, use Many advantages such as high safety are widely used in electronic devices or lighting fixtures. [0003] The light attenuation and lifetime of the LED light source are directly related to its junction temperature. LED lights, especially high-power LED light sources, concentrate heat when emitting light. If the heat generated by the LED chip is not released in time, the junction temperature will...
