At present, commercially available LED bulb comprises lamp holder, lampshade, aluminium base, be fixed on the LED on the aluminium base, the bottom of aluminium base is fixed with the aluminium alloy heat abstractor, lamp holder is fixed on the bottom of aluminium alloy heat abstractor, lamp holder is electrically connected with LED, lampshade is fixed on the top of aluminium base, be used to cover LED, when the LED operating illumination, the light that LED produces can see through lampshade and shine out, reach illumination purposes, but, above-mentioned LED bulb is when work, because LED can produce a large amount of heats, have only aluminium alloy heat abstractor that the heat that LED produces is distributed in time by the aluminium base bottom, the operate as normal that could keep LED, otherwise, can cause shorten the service life of LED, even burn out, so, existing LED bulb generally all can be fixed on LED on the aluminium base, and the aluminium alloy heat abstractor is set, yet, the weight of aluminium base and aluminium alloy heat abstractor is bigger, and take the certain volume of LED bulb, make that the weight of existing LED bulb is big, volume is big, the production cost height.
The utility model content:
The purpose of this utility model is exactly to provide the LED that a kind of weight is little, volume is little, production cost is low bulb at the deficiency of prior art existence.
To achieve these goals, the technical solution adopted in the utility model is:
It comprises lamp holder, lampshade, LED, circuit board, described LED is weldingly fixed on circuit board, and the bottom of lampshade opening is fixed on the top of lamp holder, and circuit board is fixed in the lampshade, be filled with the mist that is used to conduct heat in the lampshade, circuit board is electrically connected with lamp holder.
Described LED is an adopting surface mounted LED.
Described LED is a plurality of, and is evenly distributed on the front and back of circuit board.
Described circuit board is provided with the support bar that is used for the support fixation circuit board.
Described lampshade is a transparent glass cover.
Described circuit board is provided with rectification module, and the input of rectification module is connected with the ac input end of lamp holder, and LED is connected in series between the cathode output end and cathode output end of rectification module.
The utility model beneficial effect is:
A kind of LED bulb that the utility model provides comprises lamp holder, lampshade, LED, circuit board, described LED is weldingly fixed on circuit board, the bottom of lampshade opening is fixed on the top of lamp holder, circuit board is fixed in the lampshade, be filled with the mist that is used to conduct heat in the lampshade, circuit board is electrically connected with lamp holder; Owing to be filled with mist in the lampshade of the present utility model, when the LED operating illumination, LED can produce heat, and the mist in the lampshade then can rise mobile because of being heated, thereby the heat that LED produces is conducted to the inner surface of lampshade, distribute by lampshade again; Therefore, the utility model need not bigger aluminium base of erection weight and aluminium alloy heat abstractor, the heat that LED produces can be distributed, and has the advantages that weight is little, volume is little, production cost is low.
