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

Embodiment 1

[0054] A specific embodiment of an LED fluorescent lamp that can directly replace fluorescent lamps according to the present invention

[0055] one of the Figure 1 to Figure 5 As shown, it includes a lamp tube 1, an end cap 2 and an external LED power supply. The end caps 2 are respectively arranged at the two ends of the lamp tube 1. The external LED power supply is electrically connected to the lamp tube 1. The end cap 2 is set There are two terminals 3, and the terminal 3 includes an inner end arranged on the inside of the end cover 2 and an outer end arranged on the outside of the end cover 2, and a conductive member 4 is passed between the inner ends of the two terminals 3 on the same end cover. short circuit, the lamp tube is provided with a DC input terminal 5 .

[0056]The LED fluorescent lamp of the present invention, which can directly replace the fluorescent lamp, can be directly installed at the position of the original fluorescent lamp 21 without changing any ci...

Embodiment 2

[0059] An LED fluorescent lamp that can directly replace fluorescent lamps. The other structures of this embodiment are the same as those of Embodiment 1, except that the inner ends of the two terminals 3 arranged on the same end cap 2 are short-circuited by conductive sheets. . The use of conductive sheets can facilitate production and processing.

[0060] The lamp tube 1 includes a radiator 6 and a lampshade 7 , and the radiator 6 and the lampshade 7 are connected to each other to form a hollow cylindrical lamptube 1 . The shape of the lamp tube 1 is basically the same as that of the fluorescent lamp 21 , which can better match the original lamp holder of the fluorescent lamp 21 .

[0061] The cooling body 6 is provided with a groove 8 , and the lampshade 7 is provided with a raised strip 9 , and the raised strip 9 is connected with the groove 8 in cooperation. The fastening method of the protruding strip 9 and the groove 8 facilitates the installation and disassembly of t...

Embodiment 3

[0067] An LED fluorescent lamp that can directly replace fluorescent lamps. The other structures of this embodiment are the same as those of Embodiment 1, except that the radiator 6 and the lampshade 7 are interlocked to form a hollow cylindrical lamp tube 1 . The fastening method is adopted to facilitate the installation or disassembly of the radiator 6 and the lampshade 7 .

[0068] The external LED power supply is an external LED power supply 14 with a starter interface terminal, and the external LED power supply 14 with a starter interface terminal includes an LED power supply circuit 15 and two LED power supply circuits electrically connected to the LED power supply circuit 15. The starter interface terminal 16 and the insulating casing, the LED power supply circuit 15 is arranged inside the insulating casing, the LED power supply circuit 15 is electrically connected to one end of the two starter interface terminals 16, and the LED power supply circuit 15 is connected to a...

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...
