Embodiment approach

[0028] Optimally, see figure 2 , as an embodiment of the LED heat sink provided by the present invention, the through holes have the same shape and size and are evenly distributed on the middle part 11 at equal intervals. This uniform distribution makes the copper strips 13 lead to the aluminum basic body 1 and the heat is relatively uniform, so that the heat dissipation ribs 12 on the aluminum basic body 1 are fully utilized to dissipate heat, and the overall heat dissipation capacity of the radiator is improved.

[0029] optimally, see figure 1 and figure 2 , as an embodiment of the LED heat sink provided by the present invention, the through hole is a hole with a circular cross section, and the copper strip 13 is cylindrical. In the case of a certain cross-sectional diagonal or the maximum size of the opposite side, the cylindrical shape has a larger side area and bottom area than the prismatic shape. Therefore, the contact surface with the aluminum base body 1 and the ...

Abstract

The invention is suitable for the technical field of production of a lighting lamp radiator, and provides an LED (light-emitting diode) radiator and an LED lamp. The LED radiator comprises an aluminum base body; the aluminum base body includes a middle part of a hollow section; a plurality of radiating ribs are distributed on the surface of the aluminum base body; a copper element is also embedded in the aluminum base body; the LED lamp comprises a lamp shell, an LED light source, an aluminum base plate, and a radiator; the LED light source is arranged inside the lamp shell; the LED light source is arranged on the aluminum base plate; the radiator is fixedly connected with the aluminum base plate; and the radiator is the LED radiator. According to the LED radiator and the LED lamp provided by the invention, the copper element with higher thermal conductivity is embedded in the traditional aluminum base radiating body, so that the radiating effect of the radiator is greatly improved under the situation that area and size of a radiating sheet are not increased, thereby ensuring the service life of the LED inside the lamp.

Description

technical field [0001] The invention belongs to the technical field of radiator production for lighting lamps, and more specifically relates to an LED radiator and an LED lamp provided with the LED radiator. Background technique [0002] Now there are two main types of LED radiators, one is die-casting aluminum radiator, the thermal conductivity of die-casting aluminum is low, such as ADC12, A380, etc., the thermal conductivity is generally 96.2W / m.K; the other is aluminum extrusion profile radiator , such as 6063, the thermal conductivity is generally 209W / m.K. With the continuous improvement of LED power, especially high-power integrated package COB LEDs, the requirements for heat sinks are getting higher and higher; the most important thing for natural convection heat dissipation is the effective heat dissipation area. Increasing the heat dissipation area can be achieved by increasing the length of the heat sink. However, LED tends to be miniaturized, which is generally ...
