Abstract
The utility model discloses a lamp shade of an LED lighting lamp. The utility model is composed of an encloser, and shade end covers as well as light penetrating shade covers, which are arranged at both ends of the encloser, wherein both sides of the encloser are provided with inserting slots which are used for supporting an LED substrate. The utility model is characterized in that the back of the encloser is provided with radiating fins which are distributed at intervals. The inner side of the encloser is also provided with T-shaped heat absorption fins which are arranged at the places corresponding to the radiating fins on the back of the encloser. The encloser and the shade end covers are made of aluminium alloy. Compared with lamp shades of LED lighting lamps of the prior art, the utility model has the advantages of quick heat radiation, low temperature in the lamp shade, high light extracting rate of the LED and long service life of LED.
Description
Technical field
The utility model relates to a kind of lampshade, relates in particular to a kind of lampshade of LED illuminating lamp.
Background technology
Under the background that the worry of current global energy shortage raises once again, energy savings is the important problem that we shall face future, at lighting field, the application of LED luminous product is just attracting common people's sight, LED is as a kind of novel green light source product, must be developing tendency in future, it be the novel illumination light source epoch of representative that 21st century will enter with LED.
Be called as the 4th generation lighting source or the LED of green light source, have characteristics such as energy-saving and environmental protection, the life-span is long, volume is little, can be widely used in fields such as various indications, demonstration, decoration, backlight, general lighting and urban landscape.
Based on above-mentioned advantage, the LED illuminating lamp is being widely used in lighting field, and existing LED illuminating lamp is to be located at LED and the cover lampshade thereon that base pulls by many arrangements to constitute.Though single LED work, caloric value is very little, and many LED combine work, and caloric value is just very big, and these LED are closed in the lampshade, and heat is difficult for distributing.Therefore, the LED illuminating lamp works long hours, and the temperature in the lampshade will raise.If LED works under the hot conditions of not having heat radiation like this for a long time, light meeting decay, light emission rate will seriously reduce.Like this, LED will fail electric energy is effectively transformed luminous energy owing to heating, thereby has lost the power savings advantages of real meaning, will be affected greatly service life simultaneously.
The utility model content
Technical problem to be solved in the utility model provides a kind of heat that can distribute fast in the lampshade, thereby can strengthen light emission rate, realizes truly energy-conservation and prolongs the lampshade of the LED illuminating lamp in LED service life.
The utility model technical solution problem realizes by technical scheme once:
A kind of lampshade of LED illuminating lamp is made of case, the cover end cap that is set in the case two ends and printing opacity cover cap, and the both sides of described case are provided with supports the slot that the LED base is pulled; It is characterized in that: the back of described case is spaced and is provided with fin.
Described case is provided with the heat absorbing sheet of T type in the relative inboard of back fin.
Described case and cover end cap are case and cover end cap for aluminium alloy.
Adopt above technical scheme, the utility model is provided with fin and heat absorbing sheet on case, increased the heat absorption and the cooling surface area of case, has accelerated the radiating rate of lampshade; Because aluminum alloy material has good heat conductivity, case of the present utility model and cover end cap adopt aluminum alloy material, have further accelerated the radiating rate of lampshade again.Therefore, the utility model has rapid heat dissipation with respect to the lampshade of LED illuminating lamp of the prior art, keeps low temperature in the cover, has improved the light emission rate of LED, prolongs the LED advantage in service life.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model case;
Fig. 3 is the structural representation of the utility model cover end cap.
The specific embodiment
As the lampshade of Fig. 1, Fig. 2 and a kind of LED illuminating lamp shown in Figure 3, constitute by case 1, cover end cap 2 and printing opacity cover cap 3.Described case 1 and cover end cap 2 adopt aluminum alloy material.Cover end cap 2 adopts the two ends that are set in case 1 with the corresponding shape of case 1 end face, and printing opacity cover cap 3 is located at the opening part 108 of case 1, thereby makes whole lampshade form an enclosed construction.
Case 1 is pulled 102,103 one by upper plate 101, both sides and is constituted, and wherein biside plate 101,103 is provided with the slot 104,105 that supports the LED substrate.The back of the upper plate 101 of case 1 is spaced and is provided with fin 106, also is spaced the heat absorbing sheet 107 that is provided with the T type with respect to the inboard of the upper plate of fin 106.
Above-mentioned only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some distortion and improvement, these also should be considered as belonging to protection domain of the present utility model.
Claims (3)
1, a kind of lampshade of LED illuminating lamp is made of case, the cover end cap that is set in the case two ends and printing opacity cover cap, and the both sides of described case are provided with supports the slot that the LED base is pulled; It is characterized in that: the back of described case is spaced and is provided with fin.
2, the lampshade of LED illuminating lamp according to claim 1 is characterized in that: the heat absorbing sheet of the T type that is provided with in the relative inboard of back fin of described case.
