Abstract

The invention discloses an LED (light emitting diode) lamp which comprises a light-emitting lamp cover, a cooling base, more than two LED light emitting units, a layout circuit conductive layer electrically connected with the more than two LED light emitting units, and a lamp cap, wherein the LED light emitting units are fixed on the cooling base; cooling straight through holes matched with the arrangement manner of the LED light emitting units 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 penetrate through the light-transmitting lamp cover and the cooling base; the two ends of the cooling straight through holes are both communicated with outside air to form a convective air cooling channel; cooling fins are extend to one surface of the cooling base, which faces the lamp cap; each cooling fin is provided with a clamping groove, and bosses matched with the clamping grooves are arranged at the inner side of the lamp cap; the two ends of the cooling straight through holes are both communicated with outside air, and lateral clearances between the cooling straight through holes and 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 ...
