Description

A kind of LED light tube

technical field

The utility model relates to an LED lamp, in particular to an LED lamp tube.

Background technique

Due to the advantages of energy saving, good luminous efficiency, and long service life, LED light sources have been widely accepted and popularized by the market. Among them, there is a type of LED light tube, which is specially used to replace traditional fluorescent lamps.

As a commonly used lighting fixture, fluorescent lamps are commonly used in homes or various public places. Traditional fluorescent lamps are harmful to the environment and human health due to the toxicity of their raw materials. In addition to the advantages of power saving, good luminous efficiency, and long life, it can also avoid toxic pollution. It can be said to be a very ideal substitute for fluorescent lamps.

However, for the field of tube lamps, the use of LEDs as light sources will also have some disadvantages due to their characteristics. The main manifestation is that because LEDs are point light sources, the continuity of light emission when combined into a line light source structure is insufficient. Increase LED density and improve the lens structure on the front of the lamp to make up for it, but it is only limited to a single lamp; if multiple lamps are required to increase the luminous length, the lamp caps at both ends of the light need to be used as plugs for power connection , a larger distance needs to be left between the lamp tubes to connect to the external power grid, so that as shown in Figure 1, there will still be a large non-linearity between the combined lamp tubes and the lamp tubes. If the light-emitting strip is reflected in the irradiation place, there will be problems such as uneven light and shade, and poor lighting effect.

In response to these problems, people in the field have made a series of improvements to the connection scheme of the LED lamp tube. For example, on the power socket, it is designed to be inserted into each other between adjacent lamp tubes. The latter lamp tube is powered, that is, the two ends of the lamp tube, one end is a male socket and the other end is a female socket, so that when combined into a long light source, only a sufficient number of lamp tubes need to be plugged together end to end in sequence, and the first One and/or the last lamp tube can be connected to the grid externally. However, there are still a series of shortcomings in this structure, mainly reflected in the following: multi-section lamp tubes are connected at one time, so after the length and number of fluorescent lamps are connected in series to a certain value , you can no longer continue to increase the extension, otherwise the power of the entire circuit will be too large, and the lamp or power supply will be burned out; that is to say, the extension of this scheme is limited. , and stagger each other to connect to the power supply, so as to ensure that each is connected to the power supply. The structural state is shown in Figure 2. However, this not only makes the overall installation of the fluorescent lamp inconvenient, but also when the staggered lamp tubes emit light, the light is obviously not in a straight line. In general, a continuous and uniform light band cannot be formed, resulting in uneven illumination and faults, which affect the overall aesthetics; in addition, if the above-mentioned scheme is adopted, there is not enough margin between the power sockets on both sides of the entire long strip of light tube. If one of the lamp tubes fails and needs to be replaced, you have to remove the entire section of the connected lamp tubes first, then remove the faulty lamp tube and replace it with a qualified product. In this way, maintenance and replacement will be very difficult. inconvenient.
