LED light tube

Abstract

The present invention relates to an LED (Light-Emitting Diode) light tube includes a transparent tube, a phosphor layer and a base board. The phosphor layer is coated on a surface of the transparent tube, wherein a thickness of the phosphor layer is 10-100 [mu]m. The base board is arranged inside the transparent tube for carrying a plurality of LEDs (Light-Emitting Diodes), wherein the length between the LEDs and the transparent tube is H, and the distance between every two adjacent LEDs is P, and H / P is not smaller than 0.134 and H is 9.5-38 mm. Hence, the LED light tube provides enhanced uniform illumination without sacrificing intensity of illumination,

Description

technical field [0001] The invention relates to a lamp tube, in particular to a light emitting diode lighting lamp tube. Background technique [0002] A light emitting diode (LED for short) is a semiconductor component. At the beginning, it was mostly used as indicator lights, display panels, etc.; with the emergence of white light-emitting diodes, it was also used as lighting. It is a new type of light source in the 21st century, with advantages that traditional light sources cannot compare with, such as high efficiency, long life, and unbreakable. When the forward voltage is applied, the light-emitting diode can emit monochromatic, discontinuous light, which is a kind of electroluminescence effect. Changing the chemical composition of the semiconductor material used can make the light-emitting diode emit light in the near ultraviolet, visible light or infrared light. [0003] However, the specifications of fluorescent tubes have been used for many years; therefore, in o...

Problems solved by technology

Although the light-emitting diode lighting tube has inherited all the advantages of the light-emitting diode for lighting, if the light-emitting diode is simply placed in the general light-transmitting tube, it will cause glare or illuminance distribution because the light-emitting diode itself is a point light source. inequality problem

[0004] This shows that the above-mentioned existing light-emitting diode lighting tube obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
