Abstract

The utility model discloses an electrodeless lamp which comprises a closed space. The space is formed by glass material or other lamp material; the inner wall of the glass material is uniformly distributed with fluorescent powder, and mercury vapor is filled in the space; the outer wall of the glass material is cylindrical, and two opposite electrode-end pipe walls of the outer wall are provided with magnetic rings; the magnetic rings are sheathed on the outer wall; and the magnetic rings are wound with a plurality of parallel coils which form a magnetic field in the same direction. The electrodeless lamp adopts electromagnetic coupling, thus leading to quick start and not being limited by environment (temperature and weather). High-frequency current is generated by a ballast, the current generates an electric field in a glass tube through the winding magnetic rings, noble gas in an ionization tube drives plasmas to move at a high speed under the action of the electric field so as to impact the mercury vapor in the tube, thus converting the steady state of the mercury vapor into a metastable state and emitting energy by ultraviolet rays, and the fluorescent powder on the inner wall of an ultraviolet exciting tube can lead the electrodeless lamp to emit visible light.

Description

Electrodeless lamp

Technical field

The utility model relates to a kind of electrodeless lamp, particularly a kind ofly is applied to the electrodeless lamp that factory building or street lighting are used.

Background technology

Lamp commonly used at present, its ubiquitous problem are that the life-span is short, and light efficiency is low, and color rendering is poor: adopt the structure of fuel oil type heated type and natural gas heated type, its consumes energy is too big; The use that mode of heating and heating surface directly influence heating system is received a mandate and is shortened.

The utility model content

Based on the problems referred to above, the utility model provides a kind of long service life, good illumination effect and energy-conservation electrodeless lamp.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of electrodeless lamp comprises closed space, and this space is by glass material or other light fixture made, uniform fluorescent material on the inwall of glass material, and be filled with mercury vapour in interior volume; The outer wall of described glass material is cylindrical, and on relative two extreme tube walls of outer wall, magnet ring is installed, described magnet ring is sleeved on the outer wall, on magnet ring, be wound with the coil in some circles formation magnetic field side by side by equidirectional, the outside of whole magnet ring is fixed by fixture, and at the some fin of the circumference uniform distribution of fixture, described fixture has the holder that can support.

This product is not owing to there is electrode, and improve useful life greatly, uses rare-earth trichromatic fluorescent powder to improve its light efficiency and color rendering greatly.Use electromagnetic coupled, starting is fast, is not subjected to environmental limitations (temperature, weather).Produce high-frequency current by ballast, make it in glass tube, produce electric field by the coiling magnet ring, rare gas in the ionization tube, make plasma high-speed motion under effect of electric field power, mercury vapour in the impact tube makes it become metastable state by stable state, and with ultraviolet form emitted energy, the fluorescent material of ultraviolet ray excited inside pipe wall makes it send visible light.This product, light harvesting are learned, electromagnetism, microphysics, high-tech intelligence, its use is not subjected to environmental limitations, all is best user mode at subzero 40 ℃ to 60 ℃.
