Plasma illuminating lamp control device

Abstract

The invention discloses a plasma illuminating lamp control device which comprises a radio frequency exciting source, a radio frequency power amplification circuit and a switching power unit. The plasma illuminating lamp control device is also provided with a microcontroller unit, wherein a radio frequency exciting source signal control and output end of the microcontroller unit is connected with a control end of the radio frequency exciting source; the frequency of output signals of the radio frequency exciting source is controlled by the microcontroller unit according to the luminescence characteristics of a plasma lamp; and the microcontroller unit controls the attenuation amplitude of an automatic attenuation control circuit to radio frequency exciting source signals according to signals output by a signal resource detecting circuit and power required to be output for exciting plasmas. The invention combines the luminescence characteristics of the plasmas, improves the luminescencequality of the plasma lamp and ensures that a light source emitted by the plasma lamp after the plasma lamp is excited is closer to the natural light, the start of the plasma lamp is more stable, andthe plasma lamp can continuously and stably give out light.

Description

technical field [0001] The invention relates to the technical field of plasma lighting, in particular to a control device for a plasma lighting lamp. Background technique [0002] Plasma is a common substance in the universe. Plasma exists in the sun, stars, and lightning, and it accounts for 99% of the entire universe. Plasma is a good electrical conductor, and electric and magnetic fields can be used to control plasma. When a high voltage is applied between the two electrodes, the discharge of the inert gas or salt is triggered, and the excitation produces strong light. Compared with other display methods, the plasma technology is obviously different, and it is one step ahead in terms of structure and composition. At present, plasma light sources are used on display screens, such as plasma TVs, for graphic display, and also for decorative balls. It is rarely used as a high-power lighting lamp. The transmission frequency of traditional drives is constant, and it is very ...

AI Technical Summary

Problems solved by technology

The transmission frequency of the traditional drive is constant, and it is very difficult to control the variable

When the power of the plasma light source is relatively large, especially when it is used for lighting, it is necessary to solve the problem of radio frequency power amplification, starting current impact, control the luminous quality of the plasma lamp so that the light emitted by the plasma lamp is close to natural light, stable start and continuous stable light emission, etc. problem, otherwise it will not only consume a lot of power but also seriously affect its stability and life
