Problems solved by technology

[0002] The heat dissipation design of LED lamps determines the working life of the lamps. In the past, the popular LED lamps usually used aluminum alloy materials to make the lamp housing with heat dissipation effect, and regardless of the heat dissipation effect, it should be relatively high in terms of cost; currently A kind of plastic-clad aluminum LED lamp is popular. Its lamp shell is made of aluminum alloy with a layer of plastic. Because the aluminum-plastic combination is very tight, it will bring a lot of trouble to recycling in the future. It can be said that it is not environmentally friendly. design plan

Embodiment Construction

[0012] See figure 1 , figure 2 , image 3 , the lamp cap 1 is installed on the lamp cap plastic part 2, the shape of the lamp cap plastic part 2 can be changed, there may or may not be a ventilation hole on it, the heat dissipation lamp body is formed by sealing the plastic part 3 and the plastic part 4, and the space between the two plastic parts A closed cavity 5 is formed, in which a heat-conducting liquid is injected. figure 1 The middle plastic part 3 and the plastic part 4 are designed in the shape of a cylinder. The two plastic parts are sealed and connected at the upper port, and there is an outlet hole in the center of the lower end to communicate with each other. The LED light source circuit board assembly 6 is installed on the bottom of the lamp body plastic part 4. On a plane, the lampshade 7 covers it, and the lampshade 7 is shown in the shape of a column bubble, but it can be in any shape. The heat energy generated by the LED light source is conducted to the ...

Abstract

LED lamps in the prior art dissipate heat through aluminum alloy materials or plastic-clad aluminum lamp housings, so that the LED lamps have the defects of being high in cost, difficult to recover and not environmentally friendly. An LED lamp in a novel structure scheme comprises a lamp cap, a lamp cap plastic part, an LED light source circuit board assembly and a lampshade, and is characterizedby further comprising a heat dissipation lamp body made of plastic, the heat dissipation lamp body is mainly formed by sealed combination of two plastic parts with different shapes, a sealed cavity isformed between the two plastic parts, heat conducting liquid is injected into the sealed cavity, heat energy generated by LEDs is rapidly conducted to the surfaces of all the positions of the heat dissipation lamp body through heat conduction of the liquid, and then the heat energy is dissipated into environment air; as the shape structural design of the heat dissipation lamp body is also special, the contact surface area of the lamp body and the air is increased to the maximum degree, the heat dissipation area is increased, the heat dissipation performance of the lamp is effectively enhanced, and it is guaranteed that the working life of the lamp meets the design requirements; meanwhile, the lamp is all made of plastic, the cost of the lamp is effectively reduced, waste recovery is facilitated, and obvious social and economic benefits are achieved.

Description

technical field [0001] The invention relates to the field of lighting, in particular to the technical field of LED lighting. Background technique [0002] The heat dissipation design of LED lamps determines the working life of the lamps. In the past, the popular LED lamps usually used aluminum alloy materials to make the lamp housing with heat dissipation effect, and regardless of the heat dissipation effect, it should be relatively high in terms of cost; currently A kind of plastic-clad aluminum LED lamp is popular. Its lamp shell is made of aluminum alloy with a layer of plastic. Because the aluminum-plastic combination is very tight, it will bring a lot of trouble to recycling in the future. It can be said that it is not environmentally friendly. design plan. Contents of the invention [0003] purpose of invention [0004] The invention provides a new scheme of LED lamps, aiming at reducing the cost of the lamps while improving the heat dissipation performance of the ...
