Abstract

An LED (light emitting diode) lamp comprises a light-transmitting lamp cover, a cooling base, LED light emitting units and a layout circuit conductive layer connected with the LED light emitting units electrically, wherein the LED light emitting units are fixed on the cooling base; cooling fins are arranged in an extending manner on one side of the cooling base, which departs from the light-transmitting lamp cover; cooling straight through holes matched with the LED light emitting units in the arrangement manner are arranged among the LED light emitting units, each LED light emitting unit is adjacent to one cooling straight through hole; the cooling straight through holes pass through the light-transmitting lamp cover, the cooling base and the cooling fins; each cooling straight through hole arranged on the cooling base is internally provided with a cooling plate, the cooling fins and the cooling plates are arranged in parallel, the two ends of the cooling plates are both connected with the cooling fins, and the sides of the cooling plates, which depart from the light-transmitting lamp cover, are level with the cooling fins; the two ends of the cooling straight through holes are both communicated with outside air, and clearances between the cooling straight through holes and the cooling plates and lateral clearances among the cooling fins form a convective air cooling channel. The LED lamp has the advantages of simple structure, convenience in installation, good cooling effect and attractive appearance.

Description

technical field [0001] The invention relates to an LED lamp for lighting, in particular to an LED bulb. 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 temperature will be very high and the lifespan will be short. According to Ares' law, for every 10°C decrease in temperature, the life span will be ...
