Abstract
An LED lamp device with heat radiation structure mainly comprises a lamp with a lamp shade for containing an LED, a connection base connected with he bottom of the lamp shade, and a plurality of cooling fins provided on the outer edge surface of the lamp shade. The cooling fin has a zigzag shape so that the cooling fin can achieve the maximal heat radiation area if the length is identical, and a heat radiating channel is formed between any two adjacent cooling fins for allowing air to flow between the cooling fins so as to achieve air cooling heat radiation.
Description
Technical field
The utility model relates to a kind of heat abstractor, particularly a kind of radiator structure that is used to assist the led lamp heat radiation.
Background technology
Because advantages such as the light-emitting diodes pipe volume is little, reaction speed is fast and pollution-free, be used in the various fields widely at present, lighting apparatus particularly, utilize light emitting diode as luminescence component, though the light-emitting diodes tube efficiency at initial stage is not as traditional lighting device, but under the improvement of new afterwards technology and material, the luminosity that light emitting diode produced has obtained large increase, and the trend that replaces traditional luminescence component is gradually arranged.
Simultaneously, under new technology and material influence, the required electric current of light emitting diode increases day by day, therefore it is big that the heat that light emitting diode produced also becomes gradually, yet, in order not make the life-span of too much heat effects to light emitting diode, the lighting device for using light emitting diode as luminescence component adopts suitable radiator structure to become one of necessary means of present lighting device.
Present common heat dissipation, for example fan or water-filled radiator, because the design space of conventional lighting device is limited, and these heat dissipation are not to design for lighting device, therefore can't be installed in lighting device inside originally to present these conventional heat dissipation, dispel the heat in order to the lighting device of assisting light emitting diode.
In order to solve the heat dissipation problem of lighting device, design in conjunction with original lighting device, a plurality of fin are set on lighting device, to utilize cooperatively interacting of conduction and air cooling heat radiation, the heat that lighting device produced is passed on a plurality of fin, heat exchange by air and fin again, thus the influence of heat illumination apparatus reduced.
Therefore yet the area size of the radiating efficiency of fin and fin is closely related, in the limited lighting device of structure space, large-area fin can't be set, and directly has influence on the radiating effect of fin; Therefore, how in limited space, the radiating effect of fin is performed to maximum, become the problem of those skilled in the art's Gonna breakthrough.
Summary of the invention
At above-mentioned defective, main purpose of the present utility model is to provide a kind of LED lamp device that is provided with the radiator structure of fin, this fin performs to maximum with area of dissipation in the limited structural design space of light fixture, and then promotes the radiating efficiency of fin.
For achieving the above object, the utility model mainly provides a kind of LED lamp device with radiator structure, mainly comprise light fixture, this light fixture has the lampshade of placing light emitting diode, the lampshade bottom is connected in Connection Block, the edge surface of lampshade is provided with a plurality of fin, these fin are wavy, therefore under equal length, they have reached the effect of maximum area of dissipation, and between any two adjacent fin, form heat dissipation channel, air is circulated between each fin, thereby reach the air cooling thermolysis.
The utility model farthest performs to maximum with area of dissipation under the condition of limited of fitting structure design space, thereby promotes the radiating efficiency of fin.

The specific embodiment
Technology contents of the present utility model and detailed description are carried out following explanation with conjunction with figs.:
With reference to figure 1, this figure is a three-dimensional structure diagram of the present utility model.As shown in the figure, lamp device of the present utility model comprises lamp socket 1, lamp socket 1 has lampshade 11 and Connection Block 12, wherein lampshade 11 is hollow cylindrical in the present embodiment, bottom position in the lampshade 11 is used to place the light emitting diode (not shown), thereby, in addition, also be provided with a plurality of splicing ears 121 in these Connection Block 12 bottoms as the luminescence component of this light fixture.Be provided with a plurality of fin 2 on the outer edge surface of this lamp socket 1, described each fin 2 is wavy, that is, by wavy bending design, make this fin 2 under the equal length condition, has bigger area of dissipation.And shown in the structure vertical view of Fig. 2, those fin 2 are distributed in distance.Overlook when watching, fin 2 is radial kenel, and forms heat dissipation channel 3 between any two-phase neighbour's fin 2, and air can circulate by this heat dissipation channel 3, thereby makes fin 2 and air carry out heat exchange.Constitutional diagram of the present utility model as shown in Figure 3.
With reference to figure 4, this figure is an operation schematic sectional view of the present utility model.As shown in the figure, the light emitting diode of lampshade 11 inside is luminous under current drives, and along with fluorescent lifetime prolongs and begins to produce heat, reach on the set a plurality of fin 2 in lampshade 11 edges (as shown by arrows) by heat that light emitting diode produced conduction of heat by lampshade 11, the heat that light emitting diode produced is dissipated on each fin 2 fast, and keeps the operating temperature of lampshade 11 internal edges and light emitting diode.Reach on the fin 2 heat again by with the air cooling effect of air heat exchange, flow away naturally from heat dissipation channel 3 by air, thereby cold air entered in this heat dissipation channel 3 once more, and carry out heat exchange action once more.By above-mentioned air circulation to reach the radiating effect of expectation.
The above is a preferred embodiment of the present utility model only, is not so promptly limits claim of the present utility model, and every other equivalence of being done in the utility model characteristic range changes or modifies, and all should be included in the claim of the present utility model.
