Novel LED (light emitting diode) lamp tube

Abstract

The invention provides a novel LED (light emitting diode) lamp tube. The novel LED lamp tube comprises an aluminum housing, a base plate, a lamp cover, a drive power source and two lamp tube plugs, wherein the lamp cover is clamped with the aluminum housing, the aluminum housing is clamped with the base plate, the aluminum housing and the lamp cover form a lamp tube, two ends of the lamp tube are clamed with the lamp tube plugs, the drive power source is inserted into one of the two lamp tube plugs, and a wiring terminal of the drive power source is connected with the base plate in insertion mode. The section of the lamp tube formed by the aluminum housing and the lamp cover is round, and the lamp cover occupies a space larger than two thirds of the circumference of the lamp tube. The novel LED lamp tube has the advantages that lamp beads on the base plate in the lamp tube are evenly heated, the problem that life of the novel LED lamp tube is influenced due to the fact that only a part of the novel LED lamp tube is heated is avoided, inner space of the aluminum housing is not limited, a large Irritation angle is achieved, a luminous range of the lamp tube is effectively enlarged, steps of insulating treatment on the drive power source, welding of wires of the drive power source, welding of a lamp panel and fixing of the plugs and screws during the production process of an existing LED lamp tube are directly omitted, and efficient production is truly achieved.

Description

technical field [0001] The invention belongs to the technical field of LED lamps, in particular to a novel LED lamp tube. Background technique [0002] In the prior art, a strip-shaped LED lamp generally consists of an aluminum casing, a driving power supply, a plug and a lampshade. The driving power supply is inserted into the aluminum casing, and plugs are installed at both ends of the aluminum casing. And the drive power pins are fixed by bolts, and the wiring is fixed by welding. The problems of this connection method are as follows: [0003] Because the LED lamp has a built-in driving power supply in a small section of aluminum shell, the temperature of the lamp tube is uneven when it is working, that is, the temperature of the part with the built-in driver will be significantly higher than that of the part without the built-in driver, which will cause the LED lamp beads of the whole lamp to work at different temperatures. In the uniform environment, the pearl light of...

AI Technical Summary

Problems solved by technology

[0003] Because the LED lamp has a built-in driving power supply in a small section of aluminum shell, the temperature of the lamp tube is uneven when it is working, that is, the temperature of the part with the built-in driver will be significantly higher than that of the part without the built-in driver, which will cause the LED lamp beads of the whole lamp to work at different temperatures. In the uniform environment, the pearl light of some LED lamps will decay seriously and the lifespan will be shortened;

[0004] Once the LED lamp fails, whether it is a driving problem or the LED lamp bead is necrotic, the whole lamp must be disassembled for inspection, including: screw removal, because the screws used for the lamp plug are all slender self-tapping screws, so 80 - 90% have slipping wire problems, which directly lead to the occurrence of problems such as the installation of the plug is not tight, and cannot be removed; the disassembly of the driver, check whether the drive is normal; the disassembly of the lamp board, check whether the lamp board is normal; After repairing, it needs to be assembled, which makes the whole maintenance process blind, cumbersome and complicated;

[0005] Also, the production process of existing LED lamp tubes includes the insulation treatment of the driving power, such as barley paper or insulating sleeve or insulating power sleeve, the welding of the driving power line, the welding of the substrate, and the fixing of the plug screw. The production process takes a long time. , affecting production efficiency;

[0006] Since the driving power is installed in the aluminum casing, its space cannot be smaller than a certain range, resulting in the problems of small luminous angle and low luminous utilization rate in the existing LED lamp tubes
