The utility model discloses a LED fluorescent tube is through setting up the power part in the lamp shade outside, effectively reduces fluorescent tube inside generating heat, has reduced the temperature of whole fluorescent tube during operation, has prolonged LED's life.

Description

LED light tube with separate power supply

technical field

The utility model relates to a light pipe with an LED as a light source.

Background technique

In the current lighting technology, light pipes using light-emitting diodes have gradually been recognized by consumers. Compared with traditional fluorescent lamps, they have the advantages of low energy consumption, no flicker, long life, and no pollution. The development direction of green lighting. However, because the existing LED light tube has a built-in drive power supply, the power supply will generate more heat during operation, which will accumulate in the light tube and be difficult to dissipate, which has a great impact on the service life of the LED.

Contents of the invention

The purpose of the utility model is to propose an LED light pipe with a separate power supply that can reduce heat generation inside the light pipe.

The LED light pipe of the utility model includes a power adapter, a lampshade and lamp holders at both ends of the lampshade, an LED lamp board is arranged inside the lamp shade, and a plurality of LED lamps are installed on the LED lamp board, especially the power adapter is arranged outside the lamp shade and Separated from the lampshade, the power adapter includes a housing and a circuit board arranged inside the housing. The housing is sealed with insulating glue. The power adapter has wires or conductive columns passing through the lampshade and electrically connected to the LED lights in the lampshade.

The power adapter can be assembled near the LED light tube according to the actual situation, for example, at the ballast of the traditional fluorescent tube.

In the LED light pipe of the utility model, the power supply part is arranged outside the lampshade and separated from the lampshade, thereby effectively reducing heat generation inside the light pipe, lowering the temperature of the entire light pipe during operation, and prolonging the service life of the LED.

Detailed ways

Example 1:

The LED light pipe of the present utility model comprises a power adapter 1, a lampshade 2 and lamp holders 3 at both ends of the lampshade 2, an LED lamp board 4 is arranged inside the lamp shade 2, and a plurality of LED lamps 5 are mounted on the LED lamp board 4, especially the The power adapter 1 is arranged outside the lampshade 2 and separated from the lampshade 2. The power adapter 1 includes a housing and a circuit board arranged inside the housing. The housing is sealed with insulating glue. The power adapter 1 has wires or conductive posts Pass through the lampshade 2 and be electrically connected with the LED lamp 5 inside the lampshade 2 .

The LED light pipe of the present utility model is provided with an LED lamp board bracket 6 inside the lampshade 2, and the section of the LED lamp board bracket 6 is semicircular, and two sides are provided with locking grooves 61, and the LED lamp board 4 is snapped into the LED lamp board The card slot 61 of the bracket 6 . The assembly method through the card slot is not only convenient, but also reduces the cost of screws, and because the fixed parts of the LED light board bracket 6 and the LED light board 4 are the two sides of the whole LED light board 4, the structure is more stable, and the LED light board The bracket 6 can cover the soldering pins and the power circuit on the back of the LED light board 4, so as to play an aesthetic role.

The circuit of the power adapter 1 includes a rectification circuit and a constant current circuit, which can rectify the alternating current to direct current, reduce the sudden change of the current and voltage of the LED lamp, and prolong the service life of the LED lamp. Since the rectifier circuit and the constant current circuit are currently widely used electronic technologies, details will not be repeated here.

The lampshade 2 is transparent or translucent. With a transparent lampshade, the light transmittance of the LED light pipe will be higher; with a translucent lampshade, the light emitted by the entire LED light pipe will be more uniform and soft. Even if a certain LED lamp fails, consumers will not be outside. felt. The translucent lampshade is best made of frosted glass, plastic and other materials, which are cheap, simple to process and very effective.

In the LED light pipe of the utility model, the power supply part is arranged outside the lampshade and separated from the lampshade, thereby effectively reducing heat generation inside the light pipe, lowering the temperature of the entire light pipe during operation, and prolonging the service life of the LED.
