Non-electrode illuminating apparatus

Abstract

The invention discloses a non-pole illumination device. In the high power generator, the IC chip controls the adjustable output frequency and the current. The closed lamp is filled with mixed inert gases. The magnetic material around the lamp and the loop winding the closed lamp and the magnetic material cover the mask anchor ear component and fasten on the lamp. Adopt the snake bracket when it has multiple anchor ear components. The invention supplies radio frequency power efficiently and steadily makes the lamps of different power and different shapes work steadily. It has reliable dimming capability. And it can decrease the amount of the component, the capacity, the loss, the heat productivity and the electromagnetic radiation and increase the operating life, reliability and security. The advantage is low cost, simple process, wide application. It can apply in all kinds of indoor and outdoor situation.

Description

Technical field [0001] The invention relates to the field of light source appliances, and more specifically, to an electrodeless lighting device. Background technique [0002] The earliest patent for electrodeless lamps was proposed by P.C. Hewitt in US 843 534 in 1907. Its structure includes a spherical bulb filled with a small amount of mercury and a coil surrounding the spherical bulb. The driving frequency of the discharge is 125-300 Hz. Hewitt's invention laid the foundation for the structure of radio frequency electrodeless discharge. In 1970, J.M. Anderson proposed an external induction coil structure in his patent US3500118, in which the induction coil is placed outside a ring-shaped closed bubble. In 1977, Hollister proposed in its patent US4010400 that the electrodeless fluorescent lamp would be more efficient under the condition of low voltage and high current. Ferrite core coupling was adopted. Under the conditions of voltage 10 volts and current 3 amperes, the loss o...

AI Technical Summary

Problems solved by technology

The traditional high-frequency power generators used in existing electrodeless lamps are prone to problems such as unstable operation, high temperature, short life, large volume, single function, non-adjustable frequency and current, high manufacturing cost and low commercial value.

[0004] In addition, the existing technology does not shield the magnetic ring used in the electrodeless lamp from electromagnetic radiation, and the wiring of the coil is on the surface of the lamp tube, which not only has poor safety, but also has large radiation, which limits the scope of application.
