Problems solved by technology

As the power of LED lamps increases, heat accumulation increases. In order to reduce thermal resistance and maintain the lamps in the normal operating temperature range, the current practice is to use a larger area of ​​heat dissipation substrate, which not only increases the cost, but also is not conducive to LED lamps. structural design

Embodiment Construction

[0016] In order to enable those skilled in the art to better understand the solution of the present invention, and to make the above-mentioned purpose, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings of the embodiments.

[0017] Such as figure 1 As shown, a heat sink suitable for LED lamps is shown. The LED lamp includes LED lamp beads 2, chips 4, circuit boards 6, heat sinks 8, and a housing 10 that seals and accommodates the above components. The chip 4 is packaged in the LED lamp bead 2, and the LED lamp bead 2 is welded on the circuit board 6, and the LED lamp bead 2 is powered by an external power supply device, wherein, the radiator 8 is arranged on the back of the circuit board 6 (non-main component welding surface), the two can be bonded together by heat-conducting insulating glue, and can also be connected...

Abstract

The invention provides a radiator for an LED lamp. According to the radiator, the LED lamp comprises a circuit board; the radiator is closely connected with one side of the circuit board; and the radiator comprises a radiating baseplate, and a plurality of radiating fins distributed and connected with one side of the radiating baseplate at intervals, and is characterized in that thicknesses of the middle part and the end part of the radiating baseplate are different. The radiator reduces the light source heat resistance of the LED lamp by improving the structure of the radiating baseplate, so as to achieve better radiating effect without increasing the cost, and facilitate the structural design of lamps.

Description

technical field [0001] The invention relates to a radiator, in particular to a radiator suitable for LED lamps. Background technique [0002] At present, LED lamps have gradually replaced incandescent lamps in various fields and become the main lighting source. Although LED lamps have higher brightness than incandescent lamps, LED lamps can only convert a small part of electric energy into light energy. The electric energy is dissipated in the lamp in the form of heat, and the LED crystal grain of the LED lamp is a semiconductor material, which is not resistant to high temperature. On the other hand, in some places with flammable and explosive dust or gas, once the temperature of the contact surface between the shell and flammable and explosive dust or gas is higher than the ignition temperature, an explosion will occur. Therefore, LED lamps must be equipped with cooling equipment to transfer the heat inside the lamp to the surrounding environment. As the power of LED lamp...
