Problems solved by technology

This will limit the optical design of the LED, and other properties, such as LED heat dissipation
[0008] Further, the power converter 105 is arranged on the back of the metal frame 103, causing another problem, reducing the life of the power supply
Because the LED lamp tube generates a considerable heat source during operation, the source converter 105 located on the back of the metal frame 103 will be heated, causing the life of the power converter 105 to be shortened

Abstract

The invention relates to an assembling of a light-emitting diode (LED) tube, especially relates to an LED tube undergoing the design of light modulation, which is similar to a fluorescent lamp (T8, T9) as common lighting. In one embodiment, the LED tube comprises a light reflection unit, a reflection cover, a secondary optical lens and a transparent ball top on the LED. The transparent ball top can light evenness and light efficiency. The invention also provides an LED assembly using higher power to reduce complexity and producing cost. The power supply of the LED tube is input from outside to prolong the service lifetime. The embodiment further includes a combination of each structure to provide higher efficiency and evenness. A better LED light modulation mode is batwing-shaped distribution.

Description

technical field [0001] The disclosure of the present invention relates to the assembly of light-emitting diode (hereinafter referred to as LED) tubes, especially LED tubes in the form of T8 and T9 tubes. Background technique [0002] LED lighting fixtures used in general lighting have gradually appeared in the market, such as replacing fluorescent tubes or bulb lamps. Although LEDs have certain advantages for general lighting applications, such as long life and high efficiency. There are also some products on the market, trying to replace T8, T9 lamps. However, fluorescent tubes are still the most popular general lighting application. At present, the low cost and efficiency of fluorescent tubes are higher than incandescent lamps, and they are still quite competitive in the market. [0003] Please refer to FIG. 1 , which is a perspective view of a conventional LED light tube 100 as a replacement for a T8 light tube. In FIG. 1 , LED 101 is photographed on the surface of ci...
