Description

A kind of LED fluorescent lamp

technical field

The utility model relates to the fields of electronic technology and LED technology, in particular to an LED fluorescent lamp.

Background technique

With the acceleration of my country's urbanization process, green, high-efficiency, energy-saving, and long-life LED lighting has gradually entered people's field of vision. The LED lighting technology, which is considered to be the lighting source of the 21st century, is becoming more and more mature. Because the LED light-emitting device is a cold light source, it has high luminous efficiency, low working voltage, and low energy consumption. People's production and life are closely related to various matching energy-saving lamps.

At present, the fluorescent lamps on the market generally use low-power LED light sources of Φ5 and Φ8. The heat generated by such fluorescent lamps for short-term lighting will not cause failures. However, once the lighting time is prolonged, the temperature of the LED light source will rise. Due to the airtight structure of the existing LED lampshade, the heat generated is not easy to dissipate, which leads to a large light decay and a short service life.

Utility model content

The utility model aims at the above-mentioned defects of the prior art, and provides an LED fluorescent lamp with environmental protection, long service life and high photoelectric efficiency.

In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

An LED fluorescent lamp, characterized in that it comprises: a cover, an LED light source, an LED aluminum substrate, a light-transmitting cover, and a radiator, the LED light source is welded on the LED aluminum substrate; the light-transmitting cover is fixed on the substrate, covering Above the LED light source; the radiator is cylindrical, with heat dissipation fins evenly distributed on the outer circumference of the cylinder, and a vacancy is provided on one side of the cylinder, and the LED aluminum substrate is fixed in the vacancy; the two sides of the radiator cylinder The end is provided with a cover, and the cover fixes the light-transmitting cover, the LED aluminum substrate, and the heat sink.

Preferably, the transparent cover is made of PC or PMMA transparent material.

It can be seen from the above technical solutions that the utility model quickly transfers the heat emitted by the LED light source to the substrate, and then guides the heat dissipation fins from the substrate, and the heat is taken away by the flowing air, so as to ensure the normal operation of the LED light source and prolong the life of the LED light source. The service life has a broad market prospect.
