High-voltage linear high-safety LED lamp tube

Abstract

The invention discloses a high-voltage linear high-safety LED (light emitting diode) lamp tube which mainly comprises a lamp tube main body and lamp caps connected with the two ends of the lamp tube main body; the lamp tube main body consists of a light-transmission cover and a base; the base and the light-transmission cover are made of plastic materials by integral forming; the light-transmissioncover is connected with the top end of the base through a clamping groove structure A; a cavity is formed in the base; a driving circuit component is arranged in the cavity; the upper part of the driving circuit component abuts against a clamping groove structure B at the upper part of the base; a substrate adapted to the clamping groove structure B is arranged in the clamping groove structure B;a light emitting diode is arranged on the substrate; an insulation stop block is arranged between the lamp tube main body and each lamp cap; clamping groove structures C are arranged on the insulation stop blocks; a substrate mounting plate is clamped to the clamping groove structures C; and the driving circuit component is a high-voltage linear constant current IC power supply. The high-voltagelinear high-safety LED lamp tube has the beneficial effects that the high-voltage linear high-safety LED lamp tube has the good insulating property, conduction pins are stopped by the insulation stopblocks so that the safety is improved effectively, and the high-voltage linear high-safety LED lamp tube has the advantages of a high-voltage linear constant current IC.

Description

technical field [0001] The invention relates to the field of lamps, in particular to a high-voltage linear high-safety LED lamp tube. Background technique [0002] LED (LED is the abbreviation of Light Emitting Diode, translated into light-emitting diode in Chinese) lamp tube is also commonly known as light tube, fluorescent tube, and its light source uses LED as the illuminant. Traditional fluorescent tubes are also called fluorescent lamps. There is a filament at each end of the lamp. The tube is filled with a small amount of argon and thin mercury vapor. The inner wall of the tube is coated with fluorescent powder. The gas between the two filaments emits ultraviolet rays when conducting electricity. Make phosphors emit visible light. Due to the heavy metal pollutant "mercury", the scrapped fluorescent tubes pollute the environment very seriously. The LED light tube uses light-emitting diodes as the light source, which has higher luminous efficiency, more energy saving, ...

AI Technical Summary

Problems solved by technology

[0003] Existing LED lamp tubes mostly use the combination of an aluminum shell structure and a light-transmitting lampshade. Although this structure has a good heat dissipation effect, when the lamp head is accidentally hit, when the PIN pin retracts into the lamp tube, it will come into contact with the aluminum lamp body. The aluminum lamp body is electrified, causing danger, low safety, and prone to conductive electric shock accidents. The production process is cumbersome and the assembly efficiency is low.
