Embodiment Construction

[0016] figure 1 Shows a schematic diagram of a lamp tube and a traditional integrated design LED driver. figure 2 A schematic diagram of the lamp tube and the LED driver according to the present invention is shown.

[0017] From figure 1 , 2 It can be seen that the LED tube 1 includes a tube body 7 and an LED driver 2. The tube body 7 is powered by the LED driver 2 to illuminate the LED tube.

[0018] The LED tube 1 includes components necessary for LED lighting, such as a tube tube and an LED assembly (not shown) contained in the tube tube, etc., because the improvement of the present invention does not lie in the parts contained in the tube tube LED components, etc., therefore, these specific content will not be elaborated.

[0019] The difference between the present invention and the prior art lies in the design of the LED driver 2.

[0020] In the prior art, the LED driver 2 is an integrated module, which includes components necessary for driving the lamp body 7 to illuminate, ...

Abstract

The invention relates to an LED (light emitting diode) driver (2) which is characterized in that the LED driver (2) at least comprises a first LED driver module (3) and a second LED driver module (4), wherein the first LED driver module (3) comprises a first electron device (5) with a first characteristic, the second LED driver module (4) comprises a second electron device (6) with a second characteristic, the second characteristic is different with the first characteristic, the first LED driver module (3) and the second LED driver module (4) is mechanically and electrically connected with each other. In the invention, a modular design is used to realize a quick change of troublesomeness electron devices in the LED driver for users, and prolong the service life of the LED driver and the lamp and the corresponding luminaires can be prolonged. Besides, as the modular conception is adopted, the design and manufacturing process can be easier.

Description

Technical field [0001] The invention relates to an LED driver, an LED lamp tube and a lamp with the lamp tube. Background technique [0002] LED is a widely used light source, and it is also a light source with a long service life. However, the lifespan of the LED driver is quite different. In particular, some electronic devices prone to failure in the LED driver often cause the replacement of the entire LED driver, which reduces the overall life of the LED driver. Therefore, unnecessary frequent replacement of the LED driver is caused. For those LED tubes integrated with such LED drivers, it will even cause the entire tube life to be shortened. In the prior art, in order to increase the life of the LED driver, some electronic devices with a longer life but larger volume and more expensive are selected. Although this prolongs the life of the LED driver, the cost is high and the volume of the LED driver is large. [0003] Therefore, there is an urgent need to solve one or more o...
