LED tube improved structure

The present invention relates to an improved structure of an LED tube, in particular to a control IC component pre-configured in the LED tube, wherein the signal contacts at both ends of the tube holder can be directly electrically connected to the lamp holder. Practical creation.

According to the conventional LED lighting fixtures, according to the pipe diameter, there are various pipe diameter specifications such as T5 type, T8 type, T9 type, T10 type, T12 type, etc., and several models are listed as the first figure ( A) to (E) are partial schematic views showing the appearance of the end positions of various LED lighting fixtures. Among them, the one shown in the first figure (A) is the T5 type LED lighting fixture, and the one shown in the first figure (B) is the T8 type LED lighting fixture, as shown in the first figure (C), that is, Another T8 type LED lighting fixture, as shown in the first figure (D), is another T8 type LED lighting fixture. As shown in the first figure (E), it is a T12 type LED lighting fixture, and each of the above The familiar LED lighting fixtures differ from each other in the size of the tube and the design of the conductive pattern at the ends.

Among the above-mentioned various conventional LED lighting fixture styles, the T8 type fluorescent tube is most commonly used as a lighting component, and therefore the T8 type fluorescent lamp is more energy efficient than the conventional tungsten filament lamp, and the brightness of the light source is better and uniform, and soft. And with the increase of the use time, such T8 fluorescent tubes are prone to "light decay" due to poor heat dissipation, which leads to the degradation of brightness, which affects the brightness of the illumination. In fact, this phenomenon occurs when the temperature exceeds 85 °C. And, once produced" After the phenomenon of light decay, it is impossible to restore the brightness that should have been. Therefore, every time you need to replace the old lamp with the brightness has been replaced, you can maintain the brightness of the lighting again. It is quite inconvenient for consumers to inconvenience, and for a long time, the cost and cost of lamp replacement are amazing, and it does not meet the principle of economic and environmental benefits.

With the advancement of technology, there has also been a breakthrough in lighting equipment. Under the environmental awareness of “energy saving and carbon reduction”, the industry has developed more energy-efficient T5 lamps and LEDs as lighting components. Or the bulb, with its high brightness and power saving characteristics, can replace the traditional T8 fluorescent tube, effectively solve the above problems and defects of the traditional T8 fluorescent tube.

The only drawback is that the T5 lamp and LED tube are different from the T8 fluorescent lamp. Therefore, the T5 lamp and LED tube cannot be directly replaced with the existing T8 fluorescent lamp holder. The redemption configuration is applicable to the lamp holders of T5 type lamps and LED tubes, in order to successfully complete the installation of T5 type lamps and LED tubes, which leads to the increased cost and cost, and is currently the T5 type tube And LED lamps are still difficult to popularize.

In view of this, the manufacturer has developed a convertible lamp holder, which is assembled with a lamp holder that is close to the fluorescent tube for the T5 type lamp or LED tube, and then the two ends of the tube holder are matched with the fluorescent lamp. The end of the tube seat is smoothly replaced with the existing T8 fluorescent lamp holder instead of the T8 fluorescent tube to provide a brighter and more energy-saving lighting function.

However, the T5 type to T8 type lamp holder can solve the requirement that the T5 type lamp tube and the LED tube are suitable for the existing T8 type fluorescent lamp socket, but the end of the lamp socket is adapted to the T8. The specification type design of the type of fluorescent lamp socket, when it is intended to be used independently for space illumination, or when multiple sets of lamps are used in series or in parallel, a predetermined type of insertion must be made on both end faces of the lamp socket. Slots, so that they can be connected in series or in parallel with different sets of connecting wires to meet different requirements. In the case of the use of the lamp socket, in addition to the above-mentioned end type conforming to the T8 type fluorescent lamp socket, it is also required to produce a lamp socket with a socket on the end surface. Moreover, the two types of lamp sockets are not interchangeable, which inevitably causes great trouble and inconvenience, and thus the cost of the derivative is also costly, and it is necessary to try to solve the improvement.

In view of the fact that the lamp holders of the T5-type lamps and LED tubes are designed with fixed ends or slots, resulting in the use and derivation of the above-mentioned defects, the creator After years of practical experience and technology in such related industries, the company has carefully researched and developed the design. After a long period of continuous trials and improved sample experiments, it has finally achieved a positive effect, and the original improved LED lamp tube improved structure.

In other words, the main purpose of the creation is to pre-set a control circuit inside a predetermined size of the lamp socket, and the lamp tube seat embedded in the lower part of the adapter is used for fitting the LED tube and pre-preceding in the LED tube. The control IC component is provided, and the signal contact between the two ends of the lamp socket can be directly electrically connected to the outside of the lamp socket, so that the wire type can be extricated to pull the signal wire out to the outside of the lamp. The utility model has the advantages that the structure is complicated, the assembly is not easy, the defect rate is high, and the wire aging is easy to cause the failure, and the innovation is advanced.

Another purpose of the present invention is to facilitate the control of the color temperature and brightness of the lamp (including other lamps of various colors) by an external controller by the above-mentioned structural device, and it is suitable for various LED lamps. It is flexible and flexible for single and one-to-many series and parallel use, and it is extremely practical and convenient.
