Problems solved by technology

However, in the actual application process, it is found that the use of integral heat-conducting materials such as cement also has the following defects: 1. The production cycle is long, and it takes a long time to solidify after the pins are packaged; Mismatched pins lead to gaps when the temperature changes, and poor contact affects heat dissipation

Embodiment Construction

[0022] The invention provides an LED lighting fixture and a heat dissipation method thereof. The lighting fixture adopts several LED lamps as light sources. These LED lights are connected to the power supply circuit through conductive pins. The way of heat dissipation is to seal at least a part of the pins in the cavity with granular heat-conducting insulating material.

[0023] The circuit connection of the pins can adopt the method in the aforementioned 200510021050.9 patent application, that is, the pins are directly connected to each other according to the designed circuit structure. Through, the insulating substrate also serves as a side wall of the cavity at the same time. The pins can be connected before or after passing through the substrate, but generally for the convenience of connection and to ensure that the LED light-emitting part is not damaged during the connection process, it is preferable to connect after the pins pass through the substrate.

Abstract

The lighting LED lamp includes a power supply loop, LED lamps, a closed cavity and granular electrically insulating and heat conducting material. The LED lamps are connected to the power supply loop through their conducting pins with at least partial length held inside the cavity; and the granular electrically insulating and heat conducting material is filled inside the cavity. The present invention also provides the heat dissipating method for the LED lamp. The present invention adopts granular electrically insulating and heat conducting material for the heat dissipating packing and has reliable heat dissipating effect.

Description

【Technical field】 [0001] The invention relates to lighting technology, in particular to an LED lighting fixture and a heat dissipation method thereof. 【Background technique】 [0002] LED, that is, light-emitting diode, has been widely used in various occasions such as landscape lighting and large-screen display due to the rapid development of main technical indicators such as brightness in recent years, and will enter the field of general lighting on a large scale. In the process of energizing and emitting light, LED will generate a lot of heat. These heats are very harmful to LED devices, and the generated heat must be dissipated by appropriate means to ensure that the LEDs work within an appropriate temperature range. Commonly used LED devices have various packaging forms, such as: cylindrical, conical, straw hat and other 2-pin LEDs, piranha LEDs, SMD LEDs, and multi-pin special-shaped LEDs, etc. Manufacturers have taken heat dissipation into consideration when designin...
