Background technology
LED is a kind of semiconductor that electric energy can be converted into visible light, it changed the incandescent lamp tungsten filament luminous with the luminous principle of energy-saving fluorescent lamp tricolor powder, and adopt electroluminescence, have long, numerous advantages such as light efficiency is high, radiationless and low-power consumption of life-span.Along with the proposition of " energy-conservation " and " green illumination " theory, LED is incorporated in the lighting gradually as light source.
At present, the light emitting source that normal lighting light fixtures such as daily bulb, desk lamp are adopted is main for it with incandescent lamp bulb or fluorescent tube basically, yet, the electro-optical efficiency of white bulb and fluorescent lamp tube is all lower, and its heat is big, and service life is short, generally only has about 3000 hours.Because the significant advantage of LED, also occurred some on the market with the bulb of LED as light source, these bulbs only are to form at the peripheral directly sheathed lampshade of LED, have influenced the light extraction efficiency of LED, and its radiating effect is not good, has shortened the service life of light fixture greatly.
Follow-on LED bulb has also appearred recently, disclosed as Chinese patent 200420083451.8 " LED lighting device " is the lighting device of light source with a plurality of low power LED that is installed on the LED lamp plate, the brightness of this low-power LED a little less than, light efficiency is lower, and light decay does not comparatively fast reach the requirement of normal illumination.And Chinese patent 200620013512.2 disclosed LED bulbs, if it adopts great power LED is light source, its radiator will be less than normal so, can not well solve heat dissipation problem.
The utility model content
Technical problem to be solved in the utility model provide a kind of rational in infrastructure, light extraction efficiency is high and the LED bulb of good heat dissipation effect.
Design a kind of LED bulb, include led light source, led light source is installed on the heat radiation lamp socket by the LED fixed head, and the PCB assembly is fixed in the heat radiation lamp socket by means of insulating part, PCB assembly upper end is connected with mounted LEDs fixed head on the heat radiation lamp socket, and the lower end is connected with lamp adapter assembly.
As the improvement of such scheme, lamp adapter assembly includes the lamp holder fixture, the lamp holder fixture be " in " shape, lamp holder fixture one end connects the heat radiation lamp socket, the other end is connected with lamp holder, the lower end of described pcb board is connected on the lamp holder.
The heat radiation lamp socket also is set with the metal lamp housing that increases heat radiation outward, and the metal lamp housing also is fixed on the lamp holder fixture.The heat radiation lamp socket is horn-like, convexes with the rib that increases area of dissipation on its outer wall.
The utility model has following remarkable result compared to existing technology:
This LED bulb structure is reasonable, light extraction efficiency is high, long service life, can replace the incandescent lamp and the fluorescent lamp of system illumination.LED bulb provided by the utility model, led light source is arranged on the metallic aluminium matter heat radiation lamp socket, and at the aluminium matter lamp housing of lamp socket overcoat dress increase heat radiation that dispels the heat, not only make the good looking appearance of bulb, and can give security for the heat radiation of LED, the overhead Position Design of LED makes the emission of luminous energy wide angle, makes illuminating effect more near conventional lamp.
This LED bulb is powered to led light source by the pcb board that is provided with in inside, not only can supply with the transformation constant current, can also realize the third gear light modulation.In addition, the utility model has not only been considered the insulation of PCB electronic component and lamp housing radiating piece in the inner chamber design, also between pcb board and insulating part, reserved very big inner space, to guarantee that product can be by various tests, particularly Hi-pot test, through repeatedly experiment, the utility model product can be by the test of 4000V AC.
