Description

Lampshade structure

Technical field

The utility model relates to daily category, particularly a kind of lampshade structure, refer to especially a kind of can be with the luminous temperature that produces of LED lamp group, see through that outer cover be done heat exchange with outside air and heat extraction fast, to reduce the lampshade of LED lamp group temperature.

Background technology

As everyone knows, the composition of conventional lamp is to adopt incandescent lamp bulb or gas discharge bulb to come luminous lighting in lampshade, no matter be incandescent lamp bulb or gas discharge bulb, its principle of luminosity all is to utilize electric current to heat the filament of bulb inside, and promptly the high tungsten filament of burning-point flows charged ion in filament, the heat energy that electric energy is transferred to filament by collision, it is reached a high temperature, produce visible light by the heat radiation of filament, illumination is provided; Therefore, traditional light fixture in the use, because incandescent lamp bulb or gas discharge bulb itself in the lampshade have resistant to elevated temperatures characteristic, therefore needn't consider the problem that temperature is too high in the use, so the design of lampshade is emphatically: 1, adopt heat insulation material, effectively the temperature that inner incandescent lamp bulb or gas discharge bulb produced is hedged off from the outer world, avoids hot; 2, form the minute surface of multiaspect at the lampshade inner face, be made for the light that bulb is sent and reflect, to promote the integral illumination degree; But the high power consumption and the service life of conventional lamp are not long, thus the shortcoming that has also caused the use cost height, wasted energy.

Though it is light and handy that light-emittingdiode has a volume, can save multiple advantages such as a large amount of energy, but its luminosity can't reach the level of conventional lamp always, thereby light-emittingdiode can't be applied on the actual illumination always, and its reason is relevant with the luminous efficiency of light-emittingdiode own; For improving the problem of traditional light-emittingdiode luminance shortage, exploitation has a kind of high-power light emitting diode on the market at present, be to utilize the increase electric current to improve its luminous efficiency, reach high brightness, be made into the LED lamp and use, utilize LED lamp group to replace existing incandescent lamp bulb or gas discharge bulb illumination is provided; But, LED lamp group itself has the feature of heating owing to electrical power is high, but can't under the condition of high temperature, continue to keep luminous, therefore tradition is utilized the heat extraction mode of air nature in the lampshade, because area of dissipation is limited, can't reach the demand that makes LED lamp group maintain normal working temperature, and overheated operating temperature can cause the wafer physical characteristic in the light-emittingdiode to change, make light-emittingdiode can't reach predetermined brightness, the worry of damage is more arranged, influence service life and usefulness, need be improved.

The utility model content

According to the purpose of this utility model, the shortcoming at existing lampshade exists provides a kind of lampshade structure, and it comprises: a lamp socket; One outer cover is to be located on the above-mentioned lamp socket, and this outer cover is made of height heat radiation material, and it has a plate body, is that the center of circle is the radiating fin that radioactive ray are laid a cup-shaped downwards in this plate body periphery with this plate body center; One LED lamp group is arranged on the plate body in the above-mentioned outer cover, and contact with this plate body form; When the conducting of LED lamp group was luminous, the thermal energy transfer that can LED lamp group be produced by plate body was done heat exchange to the radiating fin surface with outside air, keeps the normal working temperature of LED lamp group.

Advantage of the present utility model is: can increase area of dissipation, improve radiating efficiency, help the heat extraction of inner LED lamp group, promote the operand power of LED lamp group, the increase effective utilization also increases the service life.
