Embodiment Construction

[0020] Such as Figure 1 to Figure 4 As shown, an LED lamp tube with a built-in power supply includes a lamp body 1, a lamp holder 3 arranged at both ends of the lamp body 1, and a lamp board 4 and a power supply assembly 5 installed inside the lamp body 1. The lamp body 1 includes a heat-dissipating aluminum profile 6 and the lampshade 7. The lampshade 7 is plugged into the heat-dissipating aluminum profile 6 and configured to form a cavity 8 for installing the lamp board 4. Both ends of the lamp body 1 are provided with a connecting seat 9 for installing the lamp holder 3, and two of the cavity 8 The end opening is sealed by the connecting seat 9 and the lamp cap 3, thereby forming a sealed cavity 8 for installing the lamp board 4 and the power supply assembly 5. The lamp board 4 includes a PCB board 10 and a number of LEDs arranged on the PCB board 10 to emit light Body 11, the end of the PCB board 10 is provided with a mounting portion 12 for mounting the power supply assem...

Abstract

The invention discloses an LED (Light Emitting Diode) lamp tube with a built-in power supply. The LED lamp tube comprises a lamp body, lamp holders, a lamp panel and a power supply component, whereinthe lamp holders are arranged on two ends of the lamp body; the lamp panel and the power supply component are installed in the lamp body; the lamp body comprises heat dissipation aluminum profiles anda lampshade; the heat aluminum profiles and the lampshade are spliced to construct a cavity used for installing the lamp panel; two ends of the lamp body are independently provided with a connectingseat used for installing the lamp holders; the lamp panel comprises a PCB (Printed Circuit Board) and a plurality of LED light emitting bodies arranged on the PCB; the end part of the PCB is providedwith an installation part used for installing the power supply component; the power supply component is electrically connected with the PCB through welding; and the lamp holders are electrically connected with the installation part through traverses. The LED lamp tube with the built-in power supply is convenient in installation and high in production efficiency, the stability of the connection structure of the lamp panel and the power supply component is improved, and in addition, production cost is lowered.

Description

Technical field [0001] The invention relates to the technical field of LED lighting, in particular to an LED tube with a built-in power supply. Background technique [0002] Fluorescent tubes are commonly used lighting fixtures in people’s daily life. For example, traditional fluorescent lamps have a filament at each end of the lamp. The tube is filled with traces of argon and thin mercury vapor. The inner wall of the tube is coated with phosphor. One of the two filaments When the gas is conductive, it emits ultraviolet rays, causing the phosphor to emit visible light. Due to the heavy metal pollutant "mercury", the discarded fluorescent tubes cause serious environmental pollution. [0003] With the advancement of science and technology and the popularization of environmental protection concepts, LED (light emitting diode) lighting technology has been widely used. Since LEDs are far superior to traditional lighting products in terms of light-emitting principle, energy saving, and ...
