Abstract

The invention relates to the field of illumination lamps, and provides a high-power LED bulb capable of achieving quick cooling. The bulb comprises a lamp cap, a glass lamp shell and an LED lamp body. A containing cavity and a glass stem are arranged in the glass lamp shell, the LED lamp body comprises an LED light source and a connection pin, the LED light source is arranged on the glass stem and comprises an LED lamp wick and a fluorescent heat conduction part, the fluorescent heat conduction part is disposed on the periphery of the LED lamp wick, the LED lamp wick comprises a plurality of LED wafers or an LED chip and a heat conduction substrate, the periphery of the glass stem is sleeved with a radiator located in the containing cavity, a plurality of cooling fins are arranged on the periphery of the radiator, the top of the radiator is a heat conduction plane making close contact with the bottom of the heat conduction substrate, the radiator is additionally disposed on the periphery of the glass stem, and accordingly heat generated by the LED wafers or the LED chip can be directly transferred to the radiator through a heat conduction mode, and the quick cooling effect can be achieved.

Description

technical field [0001] The invention relates to the field of lighting fixtures, in particular to a high-power LED light bulb with rapid heat dissipation. Background technique [0002] The power consumption of LED light bulbs is lower than that of traditional incandescent light bulbs and their lifespan is longer. Due to the improvement of consumers' awareness of energy conservation and environmental protection, and as one of the energy-saving measures, the scope of use of LED bulbs has rapidly expanded. [0003] The LED light bulb is composed of a lamp holder, a glass lamp housing and an LED light bar. In March 2015, the applicant submitted a Chinese invention patent application titled "High-power heat-dissipating LED light bar and LED light bulb". While accumulating heat, it can increase the luminous power of the LED wick, so that the LED light bar can be made into a high-power structure, so that the LED bulb also has the advantages of high heat dissipation and high power, a...
