Abstract
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...
