Lamp tube type LED lamp

Abstract

The invention relates to an LED lamp. The invention provides a lamp tube type LED lamp which has the characteristics of attractive appearance, good heat dissipation, long service life, low production cost, large range of illumination and good light output ratio. The technical scheme is that the lamp tube type LED lamp comprises a lamp cover, a lamp holder and aluminium base plates arranged on the lamp holder; a group of LED lamps are arranged on the aluminium base plate; a plurality of LED units are uniformly arranged on the periphery of the lamp holder; the adjacent LED units are separated with a certain distance to form an air convection trough which is beneficial to heat dissipation; the LED unit comprises a radiator, the lamp cover and the aluminium base plates fixing the LED lamps; the radiator is arranged at one side near the centre of a circle of the lamp seat, and the aluminium base plates are arranged on the outer side surface; one group of the LED lamps are arranged on the outer surface of the aluminium base plates; and the lamp cover is arranged at the outer side of the aluminium base plates, and the edges of both sides of the lamp cover are connected with the radiators through mutually wedged grooves and protruding edges so as to surround the aluminium base plates.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a tube-type LED lamp. Background technique [0002] LED (Light Emitting Diode) is a new type of solid-state light source. It has the advantages of simple structure, light weight, small size, low energy consumption, fast response, good shock resistance, and convenient use. It belongs to energy-saving green lighting. Under the same light intensity, the power consumption and lifespan of LED lamps are significantly better than incandescent lamps, and they are the most promising light source in the 21st century. However, because LEDs use semiconductor technology, they cannot work at high temperatures like incandescent lamps, so there is a heat dissipation problem for lamps. [0003] At present, most of the LED lamps sold on the market are equipped with metal radiators on the outside of the LED lamps. Most of these additional metal radiators are exposed outside the lamp body, and the external air convec...

AI Technical Summary

Problems solved by technology

Most of these LED lamps have the following problems: 1. Small illumination range and poor light output rate; 2. Large size of LED lamps affects the overall appearance; 3. There are serious safety hazards

The specific reasons for the above problems are as follows: 1. According to the increase of the power of the LED lamp, the volume of the metal radiator installed outside the LED lamp should also increase correspondingly, that is, the additional radiator occupies most of the surface area of ​​the LED lamp; making the light source of the LED lamp The serious imbalance of the ratio between the light source and the non-luminous source will affect the illumination range of the LED lamp, resulting in a poor light output rate of the LED lamp

2. Since the metal radiator is installed outside the LED lamps, the existing LED lamps are larger in size, which directly affects the overall appearance of the lamps

At present, in order to reduce the volume of LED lamps, people often place the power conversion electronic circuits of LED lamps in the inner cavity of the radiator, so that the electronic circuits are kept at high temperature for a long time, which affects the service life of electronic components and LED lamps.

3. Since the metal radiator is exposed and easy to contact with the human body, there are serious safety hazards

[0004] In addition to the above-mentioned problems, in order to make the lamp holder and lampshade precisely connected, the production methods of the external heat sink of the existing LED lamps are 1. adopt die-casting molding, 2. carry out turning processing and molding on the basis of stretching type. These two production methods Both methods require higher production costs, thereby increasing the production costs of LED lamps
