Light-emitting diode (LED) daylight lamp capable of directly replacing fluorescent lamp

Abstract

The invention discloses a light-emitting diode (LED) daylight lamp capable of directly replacing a fluorescent lamp, and relates to the technical field of lighting. The LED daylight lamp comprises a tube, end covers, and an external LED power supply; the end covers are arranged on two end parts of the tube; the external LED power supply is electrically connected with the tube; the end covers are respectively provided with two terminals; inner ends of two terminals on the same end cover are in short circuit through a conducive element; and the tube is provided with a direct current (DC) input end. Compared with the prior art, the LED daylight lamp can be directly arranged at the position of the original fluorescent lamp, circuits are not required to be changed, the change can be easily and quickly carried out, and the LED daylight lamp is convenient and practical; the power supply is externally arranged, so that no glare, no shadow and uniform and mild light transmission can be realized; when one end is electrified, the other end is absolutely safe when touched by a hand; the heat of the power supply is dissipated outside the light, the radiating burden of the tube is lightened and the service life of the tube is prolonged; and reclamation cost can be saved and the safety standard is easily met.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED fluorescent lamp which can directly replace fluorescent lamps. Background technique [0002] LED fluorescent lamps use light-emitting diodes as light sources, which have higher luminous efficiency, more energy-saving, longer service life, and are more environmentally friendly. LED fluorescent lamps save more than 70% of electricity, and their lifespan is more than 10 times that of ordinary lamps. They have become the most ideal products to replace fluorescent lamps at this stage. [0003] In the existing technology, such as Figure 5 As shown, almost all LED fluorescent lamps on the market are LED fluorescent lamps with built-in power supply 22 . The so-called built-in power supply refers to placing the power supply inside the lamp tube. The biggest advantage of this built-in type is that it can be made to directly replace the existing fluorescent tube without making an...

AI Technical Summary

Problems solved by technology

[0005] But this LED fluorescent lamp with built-in power supply has the following defects: (1) It is difficult to replace the power supply

Although the LED fluorescent lamp with an external LED power supply solves some defects of the LED fluorescent lamp with a built-in power supply, because the power supply installation needs to change the original circuit, it can be fixed on the lamp board of the traditional fluorescent lamp, which needs to be changed again. The original light board circuit structure
