Abstract

The invention discloses an LED lamp tube. The LED lamp tube includes a metal frame, a baseplate, a light-permeable shade, LED light sources and end caps, wherein a light-permeable shade clamping groove is formed on the outer side of the metal frame, and buckles corresponding to the light-permeable shade clamping groove are arranged on the light-permeable shade; a platform is arranged on the metal frame, the baseplate is mounted on the platform, and the LED light sources are mounted on the baseplate; the metal frame on the two sides of the baseplate adopts inclined surfaces; reflective paper is adhered to the inclined surfaces; and bulges are formed on the outer surface of the metal frame. The bulges are formed on the metal frame to increase the surface area of the metal frame, so that the metal frame also can be used as a radiator, and the service life of the LED light sources is prolonged; and the metal frame on the two sides of the baseplate adopts inclined surfaces, and the reflective paper is adhered to the inclined surfaces, so as to increase light reflection, reduce light loss, improve the lighting effect and the light uniformity, and eliminate the problem of obvious light spots.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED lamp tube. Background technique [0002] 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, ...
