LED lamp tube

The present invention relates to an LED lighting fixture, and more particularly to an LED lamp.

Background technique

LED Chinese full name is a light-emitting diode, a semiconductor that converts electrical energy into visible light. LED lighting is an emerging industry that has developed in recent years and is characterized by high luminous efficiency and long service life (up to 100,000 hours). Compared with traditional lamps such as incandescent lamps and energy-saving lamps, LED lighting fixtures do not have sensitive components such as vacuum devices and high-voltage trigger circuits, and have low failure rates, maintenance-free, short response time, quick start-up, small size, and light weight. LED has good monochromaticity, concentrated spectrum, no excess infrared, ultraviolet light, no harmful substances such as mercury, less heat and radiation, thousands of faces, strong directionality, and waste can be recycled, no pollution, is typical Green lighting source. LEDs can be used to design light, compact and versatile lamps.

As is known to all, LED lamps commonly used for indoor lighting, the internal light panels are usually placed in a plane, the specific method is: first solder the LED on an insulating board with a circuit, and then pass the insulated board with the LED through the screw Fasten to the flat type mounting surface of the lamp body. However, there are many defects in the flat mounting surface, such as: the small space under the mounting surface is not convenient for the installation of the built-in power supply, and the heat dissipation is poor due to poor internal air flow, resulting in LED junctions in the LED tube. The temperature rises, exceeds the allowable junction temperature of the LED, and finally, the brightness of the LED is sharply attenuated or damaged, greatly shortening the life of the LED tube.

Summary of the invention

The technical problem to be solved by the present invention is to overcome the above drawbacks and provide an LED lamp tube with novel structure, good heat dissipation and long service life.

In order to solve the above problems, the technical solution adopted by the present invention is:

An LED lamp tube comprises a tube body, a lamp cap mounted on both ends of the tube body, a lamp board and a power source disposed in the tube body, and the LED board is soldered on the lamp board, the tube body comprises a main body and a transparent mask mounted on the main body, the main body The invention includes a light board mounting body and a heat dissipating aluminum tube, wherein: the light board mounting body is provided with at least two mounting surfaces, wherein the plane of each mounting surface is a non-parallel surface; the number of the light board is at least two They are respectively fixed to the mounting surface of the lamp board mounting body.

Further said: The lamp board mounting body is provided with two mounting faces, two mounting faces are located on two intersecting planes, and the number of the lamp boards is two, which are respectively fixed on the two mounting faces of the lamp board mounting body. on.

The mounting surface of the lamp board mounting body is coated with thermal grease.

The lamp cap is provided with a heat dissipation hole.

The power source is disposed in a cavity between the lamp board mounting body and the heat dissipating aluminum tube, and is electrically connected to the lamp board and the lamp head through the wires, respectively. The outside of the power source is wrapped with an insulating layer.

Because the above technical solution is adopted, compared with the mounting surface of the flat lamp main body in the prior art, the present invention adopts the cloth light structure of the split type light board, which not only has novel structure, but also expands the lateral angle of the LED tube, The unit illumination area is increased, and the heat dissipation space in the lamp tube is also increased. Through the vent hole on the lamp cap, the heat dissipated inside the lamp tube can be quickly and effectively discharged, and the service life is prolonged. In addition, the installation of the light board is non-planar, which makes the illumination more uniform and is beneficial to the health of the human eye.

The invention is further described below in conjunction with the drawings and specific embodiments.
