Tube-in-tube energy-saving lamp

Abstract

The invention belongs to the technical field of energy-saving lamps and particularly relates to a tube-in-tube energy-saving lamp. The tube-in-tube energy-saving lamp comprises a transparent glass sleeve, a three-primary-color light emitting tube, clamp sleeves and guide columns. The clamp sleeves are disposed at two ends of the transparent glass sleeve. Each guide column is disposed at one end of the corresponding clamp sleeve. A rectifier is disposed in each clamp sleeve. A plug is disposed between the transparent glass sleeve and each clamp sleeve. Radiating holes are formed in each plug and each clamp sleeve. A rectifying control circuit board is mounted in the rectifier. Two layers of folded reflectors are disposed on the inner wall of the transparent glass sleeve. The three-primary-color light emitting tube is disposed in the transparent glass sleeve and mounted on one side, close to the reflectors, of each plug. Each guide column is fastened to the corresponding clamp sleeve. The tube-in-tube energy-saving lamp has the advantages that by the reflectors disposed in the transparent glass sleeve, the original wasted light can be reflected to the effective lighting range, lighting intensity is increased, efficient conversion of electric energy and optical energy is achieved, energy conservation is achieved, and the lamp is suitable for being mounted in different occasions.

Description

technical field [0001] The invention belongs to the technical field of energy-saving lamps, in particular to a tube-in-tube energy-saving lamp. Background technique [0002] Energy-saving lamps are lamps that use high-brightness white light-emitting diodes as light sources. They have many advantages such as high luminous efficiency, low power consumption, long life, easy control, maintenance-free, safety and environmental protection, etc. It is a new generation of solid cold light source, light color Soft, bright, colorful, low loss, low energy consumption, suitable for long-term lighting in various public places such as homes, shopping malls, banks, hospitals, hotels and restaurants. [0003] Among them, the tube-in-tube energy-saving lamp is a new type of energy-saving product converted from T8 to T5. Using it to replace the traditional inductive T8 fluorescent lamp can save 50-70% of lighting power; and using it to replace the T5 fluorescent lamp can save 40-60% of elect...

AI Technical Summary

Problems solved by technology

[0004] However, the heat dissipation effect of the tube-in-tube energy-saving lamp in the prior art is not good. When used for a long time, the light-emitting diode is easily burned due to the increase of the temperature inside the tube; and the service life of the tube-in-tube energy-saving lamp in the prior art is not long enough. , the light stability is not very good

In addition, the tube-in-tube energy-saving lamps in the prior art have a large loss of light, so the illuminance is still not enough; moreover, the guide posts in the tube-in-tube energy-saving lamps in the prior art cannot rotate, so that they can only Installation at a specific angle, but sometimes energy-saving lamps are installed on the ceiling, and sometimes on the wall, the guide column of this fixed structure cannot meet the demand
