Problems solved by technology

[0003] The LED light tube in the traditional technology is to set a row of LED light-emitting units inside the light-transmitting light tube. However, the light tube with this design structure usually has the problem of heat dissipation. The heat generated by the LED usually needs to pass through A certain way is emitted, if not handled properly, it will greatly

Embodiment

[0016] Example: see figure 1 , figure 2 .

[0017] An LED light tube, comprising a light-transmitting shell 1, lamp caps 5 located at both ends of the light-transmitting shell 1 for providing power, and an LED unit 2 arranged inside the light-transmitting shell 1, the LED unit 2 includes an LED chip 21 and The encapsulating resin 22 covering the LED chip, each LED unit 2 is arranged extending along the axis of the lamp tube, the lower part of the LED unit 2 is connected to the heat dissipation block 3 , and the lower end of the heat dissipation block 3 is provided with a hole extending to the outside of the light-transmitting shell 1 Leg 4.

[0018] Some manufacturers will connect heat sinks at the lower part of LED unit 2, and then connect each heat sink, and emit it through the lamp caps at both ends of the lamp tube. This kind of heat dissipation structure design requires that all heat sinks be connected. , will affect the cooling effect.

Abstract

The invention relates to the technical field of an LED (light emitting diode) and particularly relates to an LED lamp tube. The LED lamp tube comprises a light transmitting shell, lamp caps and LED units, wherein the lamp caps are arranged on the two ends of the light transmitting shell and are used to provide power supply, the LED units are arranged in the light transmitting shell, each LED unit comprises an LED wafer and packaging resin covered on the LED wafer, each LED unit is arranged in a mode of extending along the axial direction of the lamp tube, heat dissipation pieces are connected under the LED units, and the lower end of the heat dissipation piece is provided with a supporting foot extending to the outside of the light transmitting shell. The LED lamp tube provided by the invention can better realize heat dissipation; and meanwhile, the structure is simple, the wiring can be easy to realize, and thus the LED lamp tube is realistically possible to be promoted and put into practice.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an LED lamp tube. Background technique [0002] LED can directly convert electricity into light. At the same time, LED has the characteristics of long life, high luminous efficiency, no radiation, impact resistance and low power consumption. In order to meet the requirements of energy saving and environmental protection, and to meet the needs of different users, more and more manufacturers have developed LED lamps to replace fluorescent lamps in traditional technology. [0003] The LED light tube in the traditional technology is to set a row of LED light-emitting units inside the light-transmitting light tube. However, the light tube with this design structure usually has the problem of heat dissipation. The heat generated by the LED usually needs to pass through If it is not handled properly, it will greatly reduce the service life of the LED lamp. [0004] Some manufacturers wit...
