Description

Lamp socket

Technical field

The utility model relates to electrical category, particularly a kind of lamp socket.

Background technology

As everyone knows, light source is to be considerable link in life, no matter be in building, or, all need enough light sources and just can throw light on, with irradiation via light source at general premises, allow people can indoor carry out desire the things that carries out, general modal light source then is a fluorescent tube, but the shared space of fluorescent tube is bigger, and not exquisiter in overall appearance;

Light-emittingdiode has been most important a kind of light emitting source in recent years, because light-emittingdiode has luminous efficiency height, long service life, not fragile, advantage such as power consumption is few, environmental protection and volume are little, early stage because luminosity deficiency usually is used in indicator lamp and display board luminous, but in recent years because under luminescent material and the technological break-through, the luminosity of light-emittingdiode has had very many liftings, especially the appearance of white light LED more makes the present conventional illumination device of light-emittingdiode replacement gradually.

Shown in accompanying drawing 1 and accompanying drawing 2, ray structure 1 commonly used has substrate 11, and substrate 11 is provided with Lamp cup 12, and Lamp cup 12 is extended with the heat conduction frame 121 that passes substrate 11, and is provided with light-emittingdiode 13 in the Lamp cup 12, and coats with epoxy resin 14;

Still there is following point in above-mentioned ray structure commonly used in use:

Ray structure 1 only utilizes heat conduction frame 121 to carry out heat conduction when heat radiation, and heat conduction frame 121 is little with the contact area of substrate 11, and also relative with the contact area of outside little, and not only heat transfer efficiency is poor, even radiating effect is very not good yet, need be improved.

The utility model content

The purpose of this utility model is to provide a kind of lamp socket, has solved problems such as lamp socket heat conduction commonly used and radiating effect be not good.

The technical solution of the utility model is: include lampshade, lamp holder and illuminator, wherein lampshade and lamp holder are connected to each other, lampshade is provided with hole, illuminator is fixed on this hole, this illuminator includes radiating part, and this radiating part has radiating surface, and lampshade has the composition surface, radiating surface by illuminator contacts with the large tracts of land on the composition surface of lampshade, makes lamp socket can utilize the lampshade heat radiation to use and reaches the heat radiation favorable effects;

Wherein, illuminator further is connected with circuit board, and this circuit board is fixed in the lamp holder;

Be provided with thermal insulation board between illuminator and circuit board, and be provided with heat insulating mattress between this thermal insulation board and illuminator;

Lampshade is set to the good material of radiating effect;

Thermal insulation board and heat insulating mattress are set to the good material of effect of heat insulation;

Radiating part is set to the good material of heat-conducting effect;

Illuminator is SMD-LED (Surface-Mount Device Light Emitting Diode SMD LED surface-mount device LED light-emittingdiode), LED (Light Emitting Diode light-emittingdiode) and associated electrical light-emitting device.

Advantage of the present utility model is: the radiating surface by illuminator contacts with the large tracts of land on the composition surface of lampshade, makes lamp socket can utilize the lampshade heat radiation to use when being dispersed in use and reaches better heat radiating effect; Have effect of heat insulation between circuit board and illuminator, can circuit board be suffered damage, practical.
