Description

A household LED fluorescent tube

technical field

The utility model relates to a lighting fixture, in particular to a household LED fluorescent lamp tube.

Background technique

In recent years, LED lights have achieved rapid development and are gradually entering the field of general lighting. Compared with traditional incandescent tungsten bulbs and fluorescent lamps, LED fluorescent lamps have the advantages of small size, low calorific value, and low power consumption, and can be started at low voltage and low current. The existing LED fluorescent lamp has a PCB board and power drive modules located at both ends of the PCB board enclosed inside the lamp tube. On the one hand, this kind of LED fluorescent lamp does not dissipate heat well, and on the other hand, the light output mode is too different from that of the existing fluorescent lamp. Does not meet the long-term use habits of people.

Utility model content

The purpose of the utility model is to provide an LED fluorescent tube with good heat dissipation performance and the same light emitting effect as the existing fluorescent lamp.

The technical scheme adopted by the utility model to solve the technical problem is: a household LED fluorescent tube, including a translucent cover and a heat dissipation cover that are interlocked with each other, a PCB board fixed in the heat dissipation cover, and a plurality of LED light-emitting diodes, the heat dissipation cover is an aluminum cover, the PCB board is an aluminum substrate, heat-conducting glue is provided between the PCB board and the heat dissipation cover, a resistor is connected between the LED light-emitting diode and the PCB board, and a rectifier module is provided on the PCB board .

Wherein, the rectification module is detachably connected to both ends of the lamp tube.

The beneficial effect of the utility model is that: the heat dissipation cover and the PCB board are both made of aluminum and connected by heat-conducting glue, the heat generated during operation can be discharged from the pipe body in time, the calorific value is greatly reduced, and a plurality of LED light-emitting diodes constitute a light-emitting light bar. The light emitting effect is the same as that of the existing fluorescent lamps, and conforms to people's usage habits.

Description of drawings

Fig. 1 is a structural representation of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Fig. 1, a household LED fluorescent tube includes a light-transmitting cover 1 and a heat dissipation cover 5 that are interlocked with each other, a PCB board 2 fixed in the heat dissipation cover 5, and a plurality of LED light-emitting diodes arranged on the PCB board 2 3. The heat dissipation cover 5 is an aluminum cover, the PCB board 2 is an aluminum substrate, a thermal conductive glue is provided between the PCB board 2 and the heat dissipation cover 5, a resistor is connected between the LED light emitting diode 3 and the PCB board 2, and the PCB board 2 There is a rectification module 4 on it, wherein, the rectification module 4 is detachably connected to both ends of the lamp tube. The heat dissipation cover 5 and the PCB board 2 of the utility model are both made of aluminum and connected by heat-conducting glue, which can run The heat generated during the operation is discharged from the tube body in time, and the calorific value is greatly reduced. A plurality of LED light-emitting diodes 3 form a light strip, and the light output effect is the same as that of the existing fluorescent lamp, which is in line with people's usage habits.

What is described above is only the preferred embodiment of the present utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the premise of the inventive concept of the present invention, some deformations and improvements can also be made, and these all belong to Protection scope of the present utility model.
