Description

A kind of LED light tube

technical field

The utility model relates to the technical field of lighting lamp tubes, in particular to an LED lamp tube.

Background technique

In the context of the current global energy shortage rising again, saving energy is an important issue we face in the future. In the field of lighting, the application of LED light-emitting products is attracting the attention of the world. LED (Light Emitting Diode) is a light-emitting diode The English abbreviation is a solid-state semiconductor device that can directly convert electrical energy into light. Therefore, LED has many advantages such as high luminous efficiency, long service life, energy saving, and environmental protection, and is more and more widely used in many fields. In the existing LED light tube, the light-emitting surface of the LED is vertical to the light-emitting surface of the light tube. The LED light tube uses multiple low-power LEDs arranged in one row or several rows, and a lampshade is added to mix the light. This kind of lamp tube has a radiation blind area, poor light mixing effect of the lampshade, uneven brightness on the lamp tube, glare phenomenon, and low light energy utilization rate. Due to the use of denser lamps, LED lamps have high heat, low efficiency and other shortcomings. The existing lamp tubes use many low-power LED lamps, and the overall cost of the lamp tubes is high.

Contents of the invention

The purpose of the utility model is to provide an LED lamp tube, which has good light mixing effect, solves the problem of glare, good heat dissipation, high luminous efficiency and low cost.

The utility model is realized through the following technical solutions:

An LED lamp tube includes a lamp tube body, and lamp holders are arranged at both ends of the lamp tube body, and is characterized in that: LED light sources are installed at both ends of the inner cavity of the lamp tube body.

Reflective cups are installed on the LED light sources installed at both ends, and the openings of the two reflective cups are arranged opposite to each other.

The middle part of the inner cavity of the lamp body is provided with two reflective sheets, and the two reflective sheets form an angle with each other.

The lamp body is composed of an upper circular tube and a lower circular tube which are airtightly connected together, the upper circular tube is made of a metal tube, the lower circular tube is a transparent material tube, and a reflective film is fixed on the inner wall of the upper circular tube .

The upper part of the circular tube and the lower part of the circular tube are both semicircular tubes, and the two reflective sheets are inclined from bottom to top to the end.

A heat sink is installed on the back of the LED light source.

Compared with the prior art, the utility model has the following advantages:

1) The LED light tube adopts the side-emitting form, and only two power-type light sources are needed to reduce the cost of the LED light tube.

2) The LED light tube adopts both ends to emit light, and two reflectors are added in the middle to improve the utilization rate of light, and the light mixing effect is good.

3) LED light tubes are used to emit light from both ends, which not only has a good light mixing effect, but also solves the problem of glare.

4) The side-emitting LED lamp only needs two light sources, which generates little heat, and the heat sink on the back of the light source has a good heat dissipation effect.
