Problems solved by technology

[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

Embodiment Construction

[0015] In order to enable those skilled in the art to better understand the solution of the present invention, and to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the embodiments and the accompanying drawings.

[0016] Such as figure 1 As shown, an LED lamp with a needle-shaped heat sink includes an LED lamp bead 2, a chip 4, a circuit board 6, a heat sink 8, and a housing 10 that seals and accommodates the aforementioned components. The chip 4 is encapsulated 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. The heat sink 8 is arranged on the back of the circuit board 6 (non-main component welding Surface), the two can be bonded together by thermally conductive insulating glue, or they can be connected to the circuit board 6 b...

Abstract

The invention provides an LED lamp with needle-shaped radiator bodies. The LED lamp comprises a circuit board. A radiating substrate is connected to one side of the circuit board in an attached manner, and a radiator comprises the radiating substrate. The LED lamp is characterized in that the radiator further comprises a plurality of needle-shaped radiating fins which are uniformly connected to one side of the radiating substrate at intervals. The LED lamp with the needle-shaped radiator bodies has the advantages that the multiple needle-shaped radiator bodies are additionally arranged on the radiator, an effect of increasing the radiating area on the premise that the structural dimension of the lamp is not increased can be realized, and accordingly the radiating ability of the radiator is improved.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp with a needle-shaped radiator. 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...
