Abstract
The utility model relates to the technical field of LED pendant lamps, particularly to a radiating structure for an LED pendant lamp, which includes a light source and a casing, wherein the light source is arranged in the casing; heat dissipation holes are arranged at the upper part of the casing; and heat dissipation holes are arranged at the lower part of the casing. Air convection formed between the heat dissipation holes at the upper part of the casing and the heat dissipation holes at the lower part of the casing greatly improves the heat radiating efficiency of the LED pendant lamp, and as no metal radiator or liquid heat conductor is additionally needed, the radiating structure is low in manufacturing cost and excellent in radiating effect.
Description
Technical field
The utility model relates to LED pendent lamp technical field, is specifically related to a kind of LED pendent lamp radiator structure.
Background technology
Because LED (light emitting diode) has that volume is little, shock-resistant, life-span length, low power consumption, chemiluminescence and do not have advantage such as mercury pollution, is widely used in the illumination use in the indoor and outdoor places such as enterprises and institutions, hall, meeting room, workshop, shop, Entertainment Plaza.
At present, the input power of LED only has 15～20% to convert light into, and all the other 80～85% forms that convert heat into discharge, if these heats can not be discharged, will cause the temperature of LED crystal grain too high, thereby influence the luminous efficiency of LED lamp, reduce the life-span of LED lamp.
In the prior art, LED pendent lamp radiator structure generally is to adopt heat dissipation metal, or liquid thermal conductivity, and above-mentioned two kinds of radiating modes all need extra increase heat abstractor, and not only manufacturing cost is high, and radiating effect is relatively poor.
Therefore, to the problem that exists in the prior art, needing badly provides a kind of technology of LED pendent lamp radiator structure particularly important.
Summary of the invention
The purpose of the utility model is the deficiency to prior art, and the LED pendent lamp radiator structure of a kind of good heat dissipation effect, low cost of manufacture is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of LED pendent lamp radiator structure is provided, comprises light source and shell, said light source is arranged in the said shell, and the top of said shell is provided with louvre, and the bottom of said shell is provided with louvre.
Wherein, said louvre is along the circumferencial direction setting of said shell.
Wherein, the evenly distributed setting of said louvre.
Wherein, said louvre is arranged at the above and below of said light source respectively.
Wherein, said shell is the cylindrical body of hollow.
Wherein, said shell is the cylindrical body of up/down perforation.
Wherein, said shell is the bullet of hollow.
Wherein, said shell is the bullet of up/down perforation.
The beneficial effect of the utility model:
A kind of LED pendent lamp radiator structure comprises light source and shell, and said light source is arranged in the said shell, and the top of said shell is provided with louvre, and the bottom of said shell is provided with louvre.
The louvre that is arranged at shell upper forms cross-ventilation with the louvre that is arranged at outer casing underpart, can greatly improve the radiating efficiency of LED pendent lamp, does not need extra increase metal heat sink or liquid thermal conductivity device, and production cost is low, good heat dissipation effect.
Description of drawings
Utilize accompanying drawing that the utility model is described further, but the embodiment in the accompanying drawing does not constitute any restriction to the utility model.
Fig. 1 is the structural representation of a kind of LED pendent lamp radiator structure of the utility model.
In Fig. 1, comprise:
1---shell, 2---light source, 3---louvre.
The specific embodiment
Below in conjunction with embodiment the utility model is elaborated.
As shown in Figure 1, a kind of LED pendent lamp radiator structure comprises light source 2 and shell 1, and said light source 2 is arranged in the said shell 1, and the top of said shell 1 is provided with louvre 3, and the bottom of said shell 1 is provided with louvre 3.
The louvre 3 that is arranged at shell 1 top forms cross-ventilation with the louvre that is arranged at shell 1 bottom 3, can greatly improve the radiating efficiency of LED pendent lamp, does not need extra increase metal heat sink or liquid thermal conductivity device, and production cost is low, good heat dissipation effect.
Further, said louvre 3 is along the circumferencial direction setting of said shell 1.Louvre 3 is along the circumferencial direction setting of shell 1, and the heat that light source 2 is produced is fully derived good heat dissipation effect.
Further, said louvre 3 evenly distributed settings.Evenly arrange, can improve radiating effect.
Wherein, said louvre 3 is arranged at the above and below of said light source 2 respectively.Louvre 3 is arranged at the above and below of light source 2 respectively, can improve radiating efficiency, also can avoid light to appear, and influences the illumination effect of LED pendent lamp.
Further, said shell 1 also can be the bullet of hollow and up/down perforation.The utility model can also be made as round platform.
Should be noted that at last; Above embodiment is only in order to the technical scheme of explanation the utility model but not to the restriction of the utility model protection domain; Although the utility model has been done detailed description with reference to preferred embodiment; Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model, and do not break away from the essence and the scope of the utility model technical scheme.
