Abstract
The utility model provides a high-power LED bulb radiator belonging to the technical field of cooling devices, and aims to provide a high-power LED bulb radiator with uniform heat dissipation and good radiating effect. The utility model adopts the technical point that an Al-based plate (2), with an LED bulb (1) installed thereon, is fixed in a groove formed on the bottom end surface of the substrate of a finned radiator (4). With the Al-based plate, with the LED bulb installed thereon, having a large-area and tight contact with the radiator, the utility model has the benefits of transferring heat produced by the LED bulb to the Al-based plate through the pin of the LED bulb, and forwarding the heat to the finned radiator in time. Through clearances among the uniformly arranged fins which are exposed to air, cold an hot air convection is realized, thereby enhancing the radiating effect and radiating uniformity, guaranteeing the LED bulb of operation at normal environmental temperatures, improving the anti-attenuation capacity of the LED bulb, and prolonging the service life of the LED bulb.
Description
Technical field
The utility model relates to a kind of high-power LED bulb radiator, belongs to the heat abstractor technical field.
Background technology:
Led light source has characteristics such as energy-saving and environmental protection, long service life, obtains people's attention day by day.But great power LED in use, can produce certain heat, if can not well solve heat dissipation problem, then can cause the decay of LED product and aging, shortens its service life greatly.
At present, high-power LED bulb all is the version of the intermediate closed of heat radiation around adopting, cooling mechanism basically.This structure causes the heat of cooling mechanism inside not conduct out timely, and inner with the outside temperature difference is big.In addition, because middle space is occupied, the contact area of aluminium base and cooling mechanism reduces, and has reduced the radiating effect of aluminium base.This structure radiating effect is not fine, and it is inhomogeneous to dispel the heat, and local temperature is higher, can have influence on the service life of LED equally.
Summary of the invention
The purpose of this utility model is to provide a kind of dispels the heat evenly, the high-power LED bulb radiator of good heat dissipation effect.
Its technical scheme is: a kind of high-power LED bulb radiator is characterized in that: in the groove of offering on the substrate bottom face of fin radiator, be fixed with the aluminium base that the LED bulb is installed.
Its technique effect is: owing to be fixed with the aluminium base that LED is installed in the groove of offering on the substrate bottom face of fin radiator, thereby the contact area that makes aluminium base that the LED bulb is installed and radiator is big and closely, helping heat that the LED bulb the is produced pin by LED is delivered on the aluminium base, and in time be delivered to fin radiator, by exposing in air the fin that evenly is provided with and the space between the fin, realized the convection current of cold and hot air, the effect of heat radiation and the uniformity of heat radiation have been improved, guaranteed that the LED bulb working under normal environment temperature, strengthen the antidamping ability of LED bulb, prolonged the service life of LED bulb.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Shown in Figure 2 as Fig. 1, a kind of high-power LED bulb radiator adopts fin radiator 4.Offer groove on the substrate bottom face of fin radiator, the another side of the aluminium base 2 of LED bulb 1 will be installed by screw 3 in the groove, be fastened on the substrate bottom face in the groove, make it to combine closely.The edge of aluminium base and the edge of groove are that interference closely cooperates.
The substrate center of fin radiator is provided with the through hole 5 that LED is connected with power circuit.
1. 6 one-tenth round shapes of the fin of radiator or other shape.Fin shape in a row arranges, the gap 7 between fin is the conducting form from a side of radiator to opposite side.
