Light fitting of high-power LED street light with external heat sink

Abstract

A high power LED street lamp with an external radiator of the invention comprises a main housing of the lamp, a shade, an LED lamp, an external radiator and a power circuit system. The main housing ofthe lamp comprises a housing (1), a hot tube connector (2), an LED lamp holder (3), a hot tube (8) and a radiating component. One end of the main housing of the lamp is provided with the hot tube connector (2). One end of the hot tube connector (2) is provided with not less one piece or one group of hot tubes connected with the LED lamp holder (3). The other end of the hot tube connector (2) is provided with at least one piece or one group of hot tubes connected with the external radiator. The external radiator consists of not less than two unit components. A radiator is arranged in the design scheme, thus being able to quickly transfer out the heat generated by a super-high power LED when in work; thereby not only being able to effectively meet the radiating demand for the high power LEDlamp, but also being able to lead the working condition temperature of a super-high power LED street lamp to be lower, lead the service life of the super-high power LED street lamp to be prolonged, effectively solve the radiating technical difficulty of high power LED, and can lead the super-high power LED street lamp to realize industrialized mass production and use.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an ultra-high-power LED street lamp. Background technique [0002] At present, the world's energy shortage has caused countries to attach great importance to energy-saving technologies. While vigorously developing renewable and clean energy such as solar energy and wind energy, countries are also increasing their efforts in rational and effective use of energy. Reflected in lighting is the continuous innovation and wide application of various new light sources. Among them, light-emitting diodes have attracted more and more attention due to their low energy consumption, high luminous efficiency, long life and high reliability, and have been gradually applied to the lighting field. Since the LED needs to be below 80 degrees Celsius, it can work reliably and normally. However, when high-power LEDs work, their instantaneous heat generation is very large, so how to solve the heat dissipation problem o...

AI Technical Summary

Problems solved by technology

However, when high-power LEDs work, their instantaneous heat generation is very large, so how to solve the heat dissipation problem of high-power LEDs has become a hot spot in the field of solid-state lighting, and the light decay caused by poor heat dissipation of high-power LEDs has also become a bottleneck on the road of solid-state lighting

Due to the technical problem of heat dissipation, it is difficult to increase the power of LEDs in the prior art, and the chip power is generally below 5W.
