Problems solved by technology

Although LEDs have many of the above advantages, due to the high heat generation of LEDs, solving the heat dissipation problem of LEDs has become a key issue in the application process of LEDs. Excessive temperature not only affects the reliability of LEDs, but also seriously affects Lifespan of LED lights
Formally due to the heat dissipation problem during the use of LEDs, the promotion and use of LED lights have been seriously affected. This phenomenon is more serious when using high-power or concentrated use of LED lights.
But so far there is no very effective technical solution to solve this technical problem

Embodiment Construction

[0019] The invention relates to a novel radiator for LED lamps, which is used to solve the problem of insufficient heat dissipation of existing high-power LED lamps. Such as Figure 1-3 As shown, an aluminum-based circuit board 1 is also fixed on the bottom surface of the radiator, and the aluminum-based circuit board 1 is provided with LED lamps 2 arranged in an array. In addition, on the outside of the aluminum-based circuit board 1 of the LED lamp A lampshade 3 for protecting the LED lamp can also be provided. The technical improvement made in the present invention is that the heat sink is composed of a heat sink substrate 4 and a main heat dissipation fin 5 fixed on the heat dissipation substrate. As for the sheet 6, in the process of actual use, if the heat dissipation effect is to be further improved, some ribs can be added on the auxiliary heat dissipation sheet 6 for heat dissipation. The main cooling fins 5 are arranged in an array and fixed on the radiator substrat...

Abstract

The invention belongs to the technical field of illumination of light emitting diodes (LEDs), and in particular relates to a novel array type radiator applied in high-power illumination. The array type natural convection high-power LED radiator comprises LEDs fixed on an aluminum-based circuit board in an array shape; the radiator consists of a radiator substrate and main radiating fins fixed on the radiator substrate; the main radiating fins are provided with auxiliary radiating fins extending outwards; the main radiating fins are fixed on the radiator substrate in an array shape; a lampshade made of a transparent material is fixed on the circuit board; and the lampshade and the aluminum-based circuit board are fixed on the radiator substrate through bolts. The radiator special for an LED lamp has good radiating performance. Due to the radiating fins arranged in the array shape, the radiator has high radiating capability, and is particularly suitable for heat radiation of high-power LED lamps.

Description

【Technical field】 [0001] The invention belongs to the technical field of LED light-emitting diode lighting, in particular to a novel array radiator used in high-power lighting. 【Background technique】 [0002] Many countries and regions, many provinces, and many cities around the world are passing regulations or other methods to abandon traditional lighting and use new technologies, such as high-power LEDs (light-emitting diodes) for traffic, street lights and other public lighting. For example, EU countries, Japan, Australia, Brazil and Canada will strictly ban the use of incandescent bulbs by 2012. Designers of medical equipment, signage, consumer electronics, home appliances, decoration, security and other lighting appliances are increasingly using high-power (1 watt or higher capacity) LED technology when developing new products. One of the main advantages of LEDs is energy efficiency, for example: high-power LEDs are extremely energy-efficient, and LEDs emit higher brig...
