Abstract

A colour lamp tube comprises a transparent and tubular outer envelope, and red, green and blue light-emitting tubes of three primary colours, which are installed in the outer envelope. Each of three light-emitting tubes has two electrodes, which are lead out through a pin at two ends of the envelope, respectively. The three light-emitting tubes are arranged such that the three light-emitting tubes show a shape, when seen from a cross-section of the envelope. The pins are fixed onto an insulating tubular cap. On one cap, there are three pins that are respectively connected to one electrode of red, green and blue light-emitting tubes, and there are also three pins on the other cap, which are respectively connected to the other electrode of red, green and blue light-emitting tubes. Wherein, the red light-emitting tube is the furthest from an outer edge of the envelope. Since a multi-lens or multi-prism structure is used in an inner-wall of the envelope, there are a better mixed effect of the three colour lights, the resource is the more economical, and the service life of the lamp tube is longer. The electrodes of three light-emitting tubes are lead out through the pins at the envelope, so that the lamp tube may be conveniently mounted, maintained, and exchanged.

Description

Technical Field

The present invention relates to a lighting lamp tube, and more particularly, to a plug-in color lamp tube that uses the principle of three primary colors to generate multicolor light.

Background technique

In the prior art, color light tubes mostly use the principle of three primary colors to generate colored light. Usually red, green, and blue primary color light-emitting tubes are installed in the tube. In order to keep the light of various colors emitted uniform, When viewed from the outside, the color and brightness are not uniform. Usually, a light mixing layer is coated on the inner wall of the outer tube. The light mixing layer absorbs a part of the light, resulting in loss of brightness and waste of resources. In addition, the light mixing effect of the color light pipe with the light mixing layer is not ideal, and the intensity and other effects of polychromatic light cannot be obtained through the light mixing layer. After adjustment, and after a long time, the light mixing layer easily falls off and loses the light mixing effect, so that other parts of the color light tube are not damaged and cannot be used due to the light mixing layer, which shortens the life of the color light tube. On the other hand, in the existing three-primary color lamp tubes, three lamps capable of generating three-primary color lights are directly packaged in one tube. Since the electrodes of each of the primary-color lamp tubes are directly led out by wires, the external electronic transformers are connected through the wires. Makes its installation and replacement very inconvenient.
