Abstract

The utility model provides a novel LED (light-emitting diode) lamp heat-radiating device, which consists of a base formed by primary die casting. The base is provided with an outlet hole; a plurality of conical heat-radiating columns are annularly arranged on the circumferential edge of the outlet hole; a heat-radiating channel is formed between any two adjacent heat-radiating columns; and a screw hole is also arranged on the outer edge of the base. With the design, the utility model realizes the real simplification in structure and reduces the production cost; and in addition, by adopting a cylindrical structure with a large bottom and a small top, the utility model increases the contact area with an aluminum substrate of the LED lamp and the surface area of a heat-radiating structure, enhances the heat-radiating capacity, conducts more heat to the heat-radiating columns, is more beneficial to air convection of a heat radiator, cannot influence the heat-radiating effect due to the wind direction, has strong practicability, and has the technical advantages of high technical integration degree, simpleness and easiness in operation and huge market prospect.

Description

The Novel LED lamp heat abstractor

Technical field

The utility model relates to a kind of heat abstractor, belongs to the electric equipment products class of people life, is specifically related to a kind of easy to usely, can improve the heat abstractor of LED light fixture.

Background technology

Existing LED lamp cooling structure on the market, it generally is the fin shape radiator that utilizes ready-made extrusion modling, form through digital control processing, there is the problem that the secondary operations operation is many, processing cost is high, and radiating effect is undesirable, the heat that makes LED produce can not well distribute, and has had a strong impact on the LED life-span.

Summary of the invention

For overcoming the deficiencies in the prior art, the utility model proposes a kind of Novel LED lamp heat abstractor.Form by one-step die casting, manufacturing procedure is few, has also guaranteed the service life of LED light fixture when having reduced production cost.

For achieving the above object, the utility model is achieved by the following technical programs: a kind of Novel LED lamp heat abstractor, comprise a base, offer wire hole on the base, week of wire hole along around being placed with some thermal columns, form heat dissipation channel between any two adjacent thermal columns, also be provided with screw hole in the extension of base.

Its thermal column is coniform.

By such design, advantage of the present utility model is:

1: this raised surface structure, increased the surface area of radiator structure, strengthen heat-sinking capability, the length of thermal column can be according to the difference of load thermal power and the length difference, its shape can be circular according to actual design, oval, square etc. Any shape.

2: adopt the big and little column structure in top in bottom, increased the contact area with the aluminium substrate of LED light fixture to greatest extent, more heat is transmitted on the thermal column, more help the cross-ventilation of radiator;

3: modern design, structure is flexible, the quantity of thermal column and arrange and can design according to the characteristic of thermal source or position etc., the function and the effect of convenient its radiator of expansion, heat dissipation channel is non-directional, can not influence heat radiation because of wind direction, traditional fin is in when heat radiation, if the direction of wind direction and fin heat dissipation channel is inconsistent, will forms obstruction and influences radiating effect, then there is not this kind situation in the utility model, expands its use value and scope greatly.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a structure vertical view of the present utility model;

Fig. 2 is a structure upward view of the present utility model;

Fig. 3 is a structural perspective of the present utility model.

Among the figure: 1, base, 2, wire hole, 3, thermal column, 4, heat dissipation channel, 5, screw hole.

The specific embodiment

Referring to figs. 1 through shown in Figure 3, offer wire hole 2 on the base 1 of the present utility model, make that the access design of circuit board is more flexible, do not gone out the restriction of line position, thermal column 3 is around being distributed on the base 1, form heat dissipation channel 4 between any two adjacent thermal columns 3, also be provided with screw hole 5 in the extension of base 1, the existence of screw hole 5 has made things convenient for base 1 and other parts of LED light fixture to be fixedly connected.

When the LED lamp is worked, its heat that comes out just can distribute gradually and come along with the conduction of thermal column 3, and the unobstructed property of heat dissipation channel 4 also can be fully and extraneous air exchange, help the cross-ventilation of radiator integral, promoted the service life of LED light fixture integral body.

In addition, because structure of the present utility model is to adopt disposable die cast, manufacturing procedure is few, thermal column 3 also can be in its top punching, realize placing of guide line or electric wire, or mix external power supply, and make light fixture of light source and power supply integration or the like, realize that the variation of radiator is used.

According to technique scheme; those skilled in the art according to actual needs; also can design more different structure forms; but the foregoing description is only enumerated for explanation the utility model; be not to be used to limit the utility model; the structure of any effects equivalent based on the conversion of the technical program institute all belongs to protection domain of the present utility model.
