Non-polar lamp

Abstract

The present invention discloses a non-polar lamp, including a lamp body, provided with a non-polar lamp circuit, wherein the circuit includes an input filter, a slow boosting rectification circuit connected with an output end of an input filter circuit, a constant pressure triggering circuit and a self-oscillation high-frequency converter and the like. The lamp of the invention transforms the commercial electricity to a direct current, and then transforms to a high-frequency electric energy, the high-frequency electric energy generates an intense magnetic field when crossing an induction coil locating on a bulb center position, the magnetic field is capable of inducing the inner of the bulb to make the gas inside the bulb to occur an avalanche ionization to form a plasma, an excited Hg atom of the plasma radiates ultraviolet of 254nm when returning to a basic state, the fluorescent powder of the inner wall of the bulb is transformed to a visible light by the ultraviolet irradiation. The non-polar lamp has superior characteristics of a high photosynthetic capacity, a high color rendering property, non stroboflash and a long lifetime.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an electrodeless lamp. Background technique [0002] At present, the luminescent lighting devices commonly used by people include fluorescent lamps, energy-saving lamps, incandescent lamps, etc., and the working principle of these light sources is to emit light through filament heating or filament ionized gas. However, they generally have many shortcomings such as low luminous efficiency, low power factor, poor light transmittance, poor color rendering, 50 Hz power frequency flicker, etc., and their service life is unstable and easy to be damaged. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide an electrodeless lamp with simple structure, high light efficiency, high color rendering, no flicker and long life. [0004] The technical solution adopted by the present invention to solve the problem is: an electrodele...
