Abstract

The utility model discloses an LED radiator, which comprises a base plate and a radiating column. The base plate is provided with a first surface for bearing the radiating column; the radiating column is almost vertical to the first surface; the radiating column is provided with a groove with an opening upwards; and the side wall of the groove is provided with a bulge plank. After the heat of the LED is transferred to the base plate, the heat is diffused in air and the flowing air takes away the heat. Compared with the prior art, the utility model can efficiently promote the radiating efficiency.

Description

A kind of LED radiator

Technical field

The utility model relates to the radiator field, is specifically related to a kind of LED radiator.

Background technology

Under the energy-conservation call in the whole world, energy-conservation tide surges forward, and along with the development of semi-conductor industry technology, the high brightness LED manufacturing technology obtains quantum jump, has promoted the employing high light effect source to replace low light efficiency light source.The large-power light-emitting diodes cost performance improves day by day, compares with the traditional lighting light fixture, and the LED light fixture does not need to use optical filtering or optical filter to produce coloured light, efficient height, photochromic pure not only, and can realize dynamic or easy color change.Keep having high colour rendering index when changing colour temperature, satisfy different application needs, great power LED is occupied an leading position in the LED street lamp.It has been development trend that city illumination LED street lamp adopts great power LED, but there is the problem of heat radiation in the LED street lamp, because great power LED when work electric energy very major part convert heat energy to, if the light fixture heat radiation is bad, internal temperature surpasses 60 degrees centigrade, and LED will the furniture light decay, lower efficiency, shorten the life-span even quit work.So heat dissipation problem is the most scabrous key of great power LED.The method of existing solution heat dissipation problem adopts the fin of monoblock more, is unfavorable for improving radiating efficiency.

The utility model content

The technical problems to be solved in the utility model is: the problem that the volume of radiator structure of the prior art and quality are big.

For solving problems of the prior art, the utility model provides a kind of LED radiator, comprising: substrate, thermal column; Described substrate has the first surface of the described thermal column of carrying, and described thermal column is vertical with described first surface substantially; Described thermal column has opening to upper groove, and described recess sidewall is provided with protruding stupefied.

Further, described protruding stupefied axial setting of prolonging thermal column.

Further, described protruding stupefied circumferential setting of prolonging recess sidewall.

Further, also be provided with the hole of through-going recess sidewall on the described thermal column.

Further, described thermal column below is provided with the external screw thread post, and described substrate is provided with internal thread hole.

Further, described thermal column is a plurality of, and is pectination and is distributed on the described first surface.

The utility model adopts inwall to have protruding stupefied thermal column, after the heat of LED is transferred on the substrate, heat is dispersed in the air, by flow air heat is taken away, and compared with prior art can effectively improve radiating efficiency.

The specific embodiment

In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.

Fig. 1 is the overall construction drawing of the utility model embodiment; A kind of LED radiator as shown in Figure 1 comprises: substrate 1, thermal column 2; Described substrate 1 has the first surface 11 of the described thermal column 2 of carrying, and described thermal column 2 is vertical with described first surface 11 substantially; Described thermal column 2 has opening to upper groove 22, and described recess sidewall is provided with protruding stupefied 23.

Fig. 3 is the vertical view of first kind of thermal column of the utility model embodiment; As shown in Figure 3, the described protruding stupefied 23 axial settings of prolonging thermal column are to be convenient to the derivation of heat more.

Fig. 4 is the vertical view of second kind of thermal column of the utility model embodiment; Described as shown in Figure 3 protruding stupefied 23 prolong the circumferential setting of recess sidewall, can be set to the form of screw thread, are convenient to expanded application.

As shown in Figure 1, also be provided with the hole 24 of through-going recess sidewall on the described thermal column 2, being convenient to the derivation of heat more, and can be in order to the draining blowdown.

Fig. 2 is the side view of the utility model embodiment thermal column; As shown in Figure 2, the thermal column below is provided with external screw thread post 25, and external screw thread post 25 can be connected with the internal thread hole (not shown) that is arranged on the substrate, so that thermal column is fixed on the substrate.

Fig. 5 is the layout viewings of a plurality of thermal columns of the utility model embodiment on substrate, and described as shown in Figure 5 thermal column 2 is a plurality of, and is pectination and is distributed on the described first surface 11, better the heat that produces is imported in the air.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
