Description

LED light tube

technical field

The utility model relates to a lamp, in particular to an LED lamp tube.

Background technique

LED light tube is a kind of light tube that uses LED as illuminant. Traditional fluorescent lamps contain heavy metal pollutants, which makes the scrapped fluorescent tubes pollute the environment very seriously. However, LED light tubes use light-emitting diodes as light sources, which have less heat generation, no noise, eye protection, wide operating voltage range, and good versatility. , The advantages of rich colors, higher light efficiency, more energy saving, longer service life, and more environmentally friendly, generally used for general lighting, office buildings, shopping malls, restaurants, schools, families, factories and other indoor lighting. Become the most ideal product to replace fluorescent tubes at the present stage. The current LED light tube is placed on a plane where the patch light source is placed. After the power is turned on, part of the light is absorbed by the metal shell or the substrate, resulting in light waste. The part of the plane light cannot be directly reflected to the light-transmitting cover, but requires multiple reflections, which consumes part of the light energy, so the light extraction efficiency will be relatively low. The brightness of the lamp tube is uneven, and the light spots can be clearly seen. Even if opalescent light-transmitting materials are used, an external power supply or a special-shaped lamp tube must be used to make the light uniform.

Utility model content

The purpose of the utility model is to provide an LED lamp tube to solve the problems of waste of light energy, low light extraction efficiency, uneven luminous brightness of the lamp tube and visible light spots.

The purpose of this utility model is to realize through the following technical solutions:

An LED lamp tube, comprising a metal frame, a substrate, a light-transmitting cover, an LED light source, and a plug. A light-transmitting cover slot is provided on the outside of the metal frame, and a The buckle corresponding to the card slot; the metal frame has a platform, the platform is installed with a substrate, and the LED light source is installed on the substrate; the metal frames on both sides of the substrate are inclined surfaces; the inclined surface Reflective paper is pasted on it.

The inclined surface is one of "V" shape or "eight" shape.

The outer surface of the metal frame is provided with protrusions.

The beneficial effects of the utility model are: the metal frame is provided with protrusions to increase the surface area, so that the metal frame can be used as a radiator at the same time, and the life of the LED light source is prolonged. The metal frame on both sides of the substrate is inclined, and reflective paper is pasted on the inclined surface to increase light reflection and reduce light loss, improve light efficiency, increase light uniformity, and eliminate obvious light spots.

1. Metal frame; 2. Substrate; 3. Reflective paper; 4. Translucent cover; 5. Plug; 6. LED light source; platform.

Detailed ways

In the embodiment shown in Figures 1 to 3, an LED lamp tube according to the utility model includes a metal frame 1, a substrate 2, a light-transmitting cover 4, an LED light source 6, and a plug 5. The metal frame 1 is provided with a translucent cover slot 8 on the outside, and the translucent cover 4 is provided with a buckle 9 corresponding to the translucent cover slot 8; the metal frame 1 has a platform 10, and the platform A substrate 2 is installed on the substrate 2, and an LED light source 6 is installed on the substrate 2; the metal frame 1 on both sides of the substrate 2 is an inclined surface; "" or "eight"; reflective paper 3 is pasted on the inclined surface; protrusions 7 are provided on the outer surface of the metal frame 1.

After the LED light source 6 emits light, the light is irradiated on the reflective paper 3 pasted on the inclined surface, and the light is directly reflected to the translucent cover 4 through the reflective paper 3, which reduces energy consumption and improves light output efficiency. The metal frame 1 is provided with protrusions 7, which greatly increases the surface area of the metal frame 1 and improves its heat dissipation performance.
