Abstract

An LED lamp comprises a light-permeable lamp cover, a radiating base, LED light emitting units, a layout circuit conductive layer and a fixing mechanism, wherein the layout circuit conductive layer is connected with the LED light emitting units electrically, and the fixing mechanism is used for fixing the LED lamp at a set position. The LED light emitting units are fixed on the radiating base. The light-permeable lamp cover and the radiating base are mounted together to form a containing cavity for containing the LED light emitting units. The fixing mechanism is fixed on the radiating base directly, integrated to the radiating base, fixed on the light-permeable lamp cover directly, or integrated to the light-permeable lamp cover. Radiating through holes, which match with the LED light emitting units in arrangement, are further arranged among the LED light emitting units. Each LED light emitting unit is adjacent to the corresponding radiating through hole which penetrates through the light-permeable lamp cover and the radiating base. Both ends of each radiating through hole are communicated with air to form an air convection radiating passage. The LED lamp has the advantages that the LED lamp is simple in structure and effective in radiating, and the service life of the LED light emitting unit is long.

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 lamp tube, LED light 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 have no lead, mercury, no flicker, energy saving and environmental protection, long service life, fast response, vibration resistance, easy maintenance, high brightness, low energy consumption, no ultraviolet radiation and environmental pollution, use Due to many advantages such as high safety, it is widely used in electronic devices or lighting fixtures. [0003] The light decay and lifetime of LED light sources are directly related to their 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 dissipated in time, the junction temper...
