Lamp tube suitable for light-emitting diode illumination

Abstract

The invention provides a lamp tube suitable for light-emitting diode illumination. The lamp tube is characterized by comprising structural components, the connecting mode of the structural components, a separation plate and an outer end device. The first structural component is used for containing a power module and materials needed in the normal work of the power module, a high-voltage power source of the contained power module is isolated by the first structural component and the separation plate structure, and a power input port and a power output port of the contained power module are reserved. The second structural component is used for containing a light-emitting diode lamp bead and materials needed by normal lighting of the light-emitting diode lamp bead, and a power input port and a power output port which are needed by the contained light-emitting diode lamp bead are reserved in the structure of the second structural component. The first structural component and the second structural component are connected in an end-to-end mode, and a power source connecting channel between the power module and the light-emitting diode lamp bead is arranged. The structural components are connected in the end-to-end mode to form two connecting and fixing devices of the lamp tube, wherein power output ports and power input ports are formed in the outer ends of the connecting and fixing devices. According to the lamp tube, the lighting effect of a composite lamp tube adopted in illumination of an existing light-emitting diode can be improved, and the cost of the materials needed by the lamp tube can be greatly lowered.

Description

technical field [0001] The invention relates to a lighting technology, in particular to a lamp tube suitable for light emitting diode (Light Emitting Diode, LED for short) lighting. Background technique [0002] With the popularity of LED lighting sources, LED lamps have also become an important type of light source for commercial and civil lighting. In order to be able to directly replace the existing traditional lighting fluorescent lamps (or fluorescent lamps) in the early stage, the specifications of the length of the LED lamp tube and the interface at both ends are consistent with the previous lamp tubes, such as T8, T5 and so on. [0003] Traditional lighting fluorescent lamps are a kind of gas discharge lamps. It uses electricity to activate mercury vapor in argon or neon gas, forming a plasma that emits short-wave ultraviolet light, causing phosphorous to fluoresce visiblely for illumination. A common fluorescent tube is usually a one-piece tube made of glass, with...

AI Technical Summary

Problems solved by technology

[0007] 1. The luminous effect of the lamp is affected: firstly, the luminous area (or angle) of the lamp is lost

Compared with the traditional integrated lamp tube, the composite lamp tube combined with PC and aluminum alloy loses up to 50% of the luminous area; secondly, compared with the glass material, the light transmittance of the PC material also causes the final luminous effect of the LED lamp to be affected. further loss

[0008] 2. A large amount of relatively high-cost materials are required: the existing composite lamp needs to use a large amount of aluminum alloy materials

Taking the most common 1.2-meter-long T8 light tube as an example, only one LED light tube needs 942 square centimeters of aluminum alloy material, which also causes a significant increase in the cost of structural parts

Using the current market material price estimation, the material cost of a composite lamp is about 6 RMB more expensive than the traditional fluorescent lamp integrated glass lamp, and the material cost is more than 10 times
