Description
Technical field
The utility model relates to lighting, and more particularly, relating to a kind of is the bulb of light source with light emitting diode (LED).
Background technology
At present, the light emitting source that indoor illumination light fitting adopted such as desk lamp is based on incandescent light bulb or fluorescent tube basically.Yet the electro-optical efficiency of incandescent light bulb and fluorescent lamp tube is all lower, and its caloric value is big, and service life is short, generally only has about 3000 hours.
And LED is as a kind of emerging light emitting semiconductor device, and it has advantages such as volume is little, caloric value is low, power consumption is low, the life-span is long, and some having occurred is the light fixture of light source with LED.These light fixtures only are to form at the peripheral directly sheathed lampshade of LED, influenced the light extraction efficiency of LED, and its radiating effect are not good, have shortened the service life of light fixture greatly.
The utility model content
The technical problems to be solved in the utility model is, at the defective of the light fixture of prior art, provide a kind of rational in infrastructure, light extraction efficiency is high, the LED bulb of good heat dissipation effect.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of LED bulb, comprise have good heat conductivility, its inner chamber is the lamp socket of reflective cup-shaped, be installed in LED lamp plate in the described lamp socket, that be equiped with LED, be connected the lampshade of bright dipping one side opening of described lamp socket, the insulation sleeve of installing at the opposite side opening of described lamp socket and at the terminal lamp holder that connects of described insulation sleeve.
In LED bulb of the present utility model, the bottom of described lamp socket and top offer the upper vent hole and the following passage that can be communicated with respectively.
In LED bulb of the present utility model, the outer surface of described lamp socket is provided with a plurality of radiating fins.
In LED bulb of the present utility model, has certain distance between the edge of bright dipping one side opening of described LED and described lamp socket.
In LED bulb of the present utility model, described LED is great power LED or common LED.
In LED bulb of the present utility model, described LED is a common LED, and pad is provided with the heat conductive insulating film below described LED lamp plate.
In LED bulb of the present utility model, described lamp socket is aluminium lamp socket or aluminium alloy lamp socket.
In LED bulb of the present utility model, described lamp holder is a standard lamp head.
In LED bulb of the present utility model, form seal cavity between described insulation sleeve and the described lamp holder, in described seal cavity, power supply is installed.
Implement LED bulb of the present utility model, have following beneficial effect:, thereby have advantages such as volume is little, caloric value is low, power consumption is low because light source is selected led light source for use; And lamp socket has good heat-conducting and inner chamber is reflective cup-shaped, can effective collection light, improve light extraction efficiency, thus have rational in infrastructure, light extraction efficiency is high, the advantage of long service life.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the decomposing schematic representation of the utility model LED bulb;
Fig. 2 is the schematic diagram of the assembled state of the utility model LED bulb;
Fig. 3 is the cross-sectional schematic of the assembled state of the utility model LED bulb.
The specific embodiment
As shown in Figure 1 to Figure 3, be an embodiment of LED bulb of the present utility model, it comprises lampshade 1, is equiped with the LED lamp plate 2 of LED 21 light sources, lamp socket 4, insulation sleeve 5, lamp holder 7.Described insulation sleeve 5 is installed in lower opening one side of described lamp socket 4, and form seal cavity between the described lamp holder 7, power supply 6 is installed in described seal cavity, offers LED lamp plate 2, light the LED 21 that is installed on the described LED lamp plate 2 thereby introduce extraneous power supply.In the present embodiment, described insulation sleeve 5 is fixing by being threaded with described lamp holder 7, can certainly select other forms of fixed form for use, for example welds, coheres, clamping etc.
Described lamp holder 7 can be selected the lamp holder of existing incandescent light bulb for use, for example E27 lamp holder or select the lamp holder of other standards for use.
Described lamp socket 4 selects for use good heat-conducting to make, for example aluminium, aluminium alloy, copper etc., and its inner chamber is reflective cup-shaped, thereby can collect the light that described LED 21 sends, to improve its light extraction efficiency.Described LED lamp plate 2 is installed in the described lamp socket 4, and has certain distance between the edge of bright dipping one side opening of described LED 21 and described lamp socket 4, thereby the light that described LED 21 is sent can well be controlled in the scope of requirement.Bright dipping one side opening of described lamp socket 4 is by the described lampshade 1 that is threaded, and described lampshade 1 can be selected transparent or semitransparent lampshade 1 for use, for example Ya Like (PMMA) lampshade, glass lamp shade etc.Described LED 21 can adopt great power LED 21 or common LED 21.When using many common LEDs 21, pad is provided with heat conductive insulating film 3 below described LED lamp plate 2, thereby can better derive the heat that LED 21 sends.Described LED lamp plate 2 can be arranged in the described lamp socket 4 by modes such as screw, stickups.In the present embodiment, on described insulation sleeve 5, offer screw, thereby can described LED lamp plate 2 be fixed on the described insulation sleeve 5, and be positioned at described lamp socket 4 by screw.
In order further to improve the radiating efficiency of whole LED bulb, offer the upper vent hole 41 and the following passage 42 that can be communicated with respectively on the bottom and the top of described lamp socket 4, thereby form cross-ventilation, guarantee the circulation of air, thereby heat is shed fast.Outer surface at described lamp socket 4 can also further be provided with radiating fin 43, thereby increases area of dissipation, improves radiating efficiency.
