ceramic substrate led fluorescent tube

Abstract

A ceramic carrier LED fluorescent tube, including a lamp tube cover and double-leg joints connected to both ends of the cover, an integrally formed ceramic substrate is provided inside the cover, and the surface of the ceramic substrate includes at least one side for The LED installation surface for installing the LED lamp and the power supply installation surface used to drive the LED lamp work are all screen-printed with a circuit made of conductive paste on each of the LED installation surface and the power supply installation surface. It is cheaper to produce, dissipates heat better, and increases the effective lighting angle.

Description

【Technical field】 [0001] The invention relates to an LED fluorescent lamp tube, in particular to an LED fluorescent lamp tube made of a ceramic billet as a circuit board carrier. 【Background technique】 [0002] At this stage, fluorescent tubes are the main lighting for lighting tubes. Of course, the most popular ones are LED tubes. Among them: [0003] Fluorescent tubes, that is, low-pressure mercury lamps, use low-pressure mercury vapor to radiate ultraviolet rays during the discharge process, so that the fluorescent powder emits visible light to emit light, so it belongs to low-pressure arc discharge light sources. Since most of the electric energy consumed by fluorescent lamps is used to generate ultraviolet rays, it is more or less harmful to the human body and surrounding substances. Fluorescent lamps have the following disadvantages: [0004] 1) Contains mercury poison, because it is discharged by mercury vapor, so if it is accidentally broken, it will immediately h...

AI Technical Summary

Problems solved by technology

[0004] 1) Contains mercury poison, because it is discharged by mercury vapor, so if it is accidentally broken, it will immediately have a major impact on the human body;

[0005] 2) High power consumption, which is generally three times higher than that of LED lamps at the same brightness;

[0006] 3) The lifespan is short. The lifespan of a general fluorescent lamp is 5000-10000 hours, which is 1/5 of the lifespan of a good LED lamp;

[0007] 4) There is ultraviolet radiation, which has an impact on the human body and will also have a qualitative change on the surrounding objects;

[0008] 5) There will be environmental protection probl
