Abstract

The invention relates to radiating structures of lamps, in particular to a radiating structure of an LED street lamp. The radiating structure of the LED street lamp comprises a lamp panel, an LED illuminating body, a radiating module and a radiating module outer shell, wherein the LED illuminating body is arranged on the lamp panel, the radiating module is connected with the LED illuminating body, the radiating module outer shell covers the outer surface of the radiating module and is connected with the lamp panel, an air duct is formed between the radiating module outer shell and the radiating module, and a fan is further connected with the air duct. Due to the fact that the fan is tightly connected with the radiating structure, cold air can be effectively transmitted to the radiating structure, and due to the fact that the radiating module outer shell is connected with the lamp panel in a sealed mode, a sealed channel is formed, sufficient heat exchange between the radiating structure and air can be well achieved, and further radiating speed is greatly increased under the situation that a good radiating structure of the LED lamp street is guaranteed.

Description

LED road lamp cooling structure
Technical field
The present invention relates to a kind of radiator structure of light fixture, especially the radiator structure of LED street lamp.
Background technology
The LED light fixture has plurality of advantages such as energy-conservation, that brightness is high, the life-span is long, and replace incandescent, fluorescent lamp etc. become the lighting source of a new generation gradually.Certainly it also has its weak point, main problem is to be influenced its life-span even can occur burning if the radiating effect of LED street lamp can cause when relatively poor the temperature of led chip to rise rapidly, particularly LED street lamp etc. seems particularly important than high-power illumination lamp heat dissipation problem, and the heat dissipation problem that therefore solves the LED street lamp is that the LED light fixture possesses long-life prerequisite.
Summary of the invention
The purpose of this invention is to provide a kind of LED road lamp cooling structure, simple, good heat dissipation effect and low cost of manufacture.
The present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of LED road lamp cooling structure, comprise light fixture panel, LED illuminator, heat radiation module and heat radiation module shell, the LED illuminator places on the light fixture panel, the heat radiation module is connected with the LED illuminator, heat radiation module shell covers heat radiation module outer surface and is connected with the light fixture panel, it is characterized in that: form the air channel between described heat radiation module shell and the heat radiation module, also have a fan to be connected with the air channel.
Preferably, the light fixture panel is provided with air vent, and air vent is located at the light fixture panel end.
Preferably, the air port in described air channel is connected with the air vent of light fixture panel respectively.
Preferably, described heat radiation module shell is made of metal material.
Preferably, described heat radiation module is formed in one, and is made up of a plurality of radiating fins.
Preferably, described heat radiation module shell and light fixture panel junction are for being tightly connected.
The invention has the beneficial effects as follows: fan closely is connected with radiator structure, can effectively make cold wind be delivered to radiator structure, and heat radiation module body seal connects the light fixture panel, thereby form the air channel of a sealing, add the design of fan, be conducive to radiator structure and air and carry out sufficient heat exchange, thereby guaranteeing that the LED street lamp has under the good radiator structure situation improves radiating rate greatly.
