Description
technical field [0001] The present invention relates to an LED light bulb, in particular to a heat dissipation structure of the LED light bulb which can improve the luminous efficiency of the LED module and has an excellent heat dissipation effect. Background technique [0002] In recent years, due to the increasingly serious problem of global warming, various energy-saving and carbon-reducing environmental protection products have been paid attention to. As far as light bulbs are concerned, incandescent bulbs are traditionally used, but incandescent bulbs consume 90% of the energy consumed in the process of lighting. % is converted into heat energy, and less than 10% of the energy will be luminous, so the luminous efficiency is low and there is a serious waste of energy. [0003] In view of the low luminous efficiency of incandescent bulbs, many light-emitting units that can replace incandescent bulbs have been developed on the market, one of which is Light Emitting Diode (...
