Abstract
The utility model relates to a power supply for neon lamps, which comprises a self-excited oscillator which works under a DC power supply, the high-frequency oscillator output of the self-excited oscillator is boosted and is provided to the transformer of a neon lamp. The utility model is safe and light in weight; the utility model utilizes the skin effect of high-frequency current to make the neon lamp tube save power; the utility model adopts the DC power supply, and therefore, the utility model has a wide application range.
Description
The utility model relates to a kind of neon lamp power source.
Traditional neon lamp power source adopts 220 volts of mains-supplied, lights neon light tube after with Industrial Frequency Transformer it being boosted.This supply unit exists that volume is big, power consumption and the shortcoming of safety inadequately.Because adopt mains-supplied, the application scenario also is restricted.
The purpose of this utility model is to provide that a kind of volume is little, the neon lamp power source of power saving and safety.
The neon lamp power source of the present utility model of realizing above-mentioned purpose comprises: by the self-excited oscillator of DC power supply; The vibration output of self-excited oscillator is boosted the back as the transformer of powering and exporting.
The utility model is owing to be with DC power supply (for example battery) power supply, thereby safety, and not limited by occasion.The vibration output of self-excited oscillator becomes the alternating current of high frequency after boosting, supply with neon light tube.Like this, utilize the kelvin effect of high-frequency current, realized the effect of economize on electricity.In addition, owing to need not the Industrial Frequency Transformer of large volume, thereby machine volume is small and light.
Following with reference to accompanying drawing detailed description the utility model.
Fig. 1 is an electrical schematic diagram of the present utility model.
Fig. 2 is the outside drawing that part of the present utility model is analysed and observe.
Referring to Fig. 1, wherein, U is the direct current input, triode BG, the base stage that is serially connected in triode BG and the capacitor C between the emitter
1, resistance R
1And inductance L, be connected on the resistance R between base stage and the collector electrode
2Form a self-excited oscillator.Be connected on the diode D between base stage and the emitter
1Be used to make the waveform symmetry, and be connected on the capacitor C between emitter and the collector electrode
2Can improve waveform.Be connected on the diode D on the primary coil of transformer T
2, capacitor C
3Be used to promote the amplitude of the vibration output of oscillator, also be used for DC boosting.Neon light tube is supplied with in the higher-order of oscillation output of self-excited oscillator after transformer T boosts.
By selecting the Resistor-Capacitor Unit of triode BG base loop, can change frequency of oscillation, be chosen in more than the 15KHz usually.
Referring to Fig. 2, wherein 1 is housing, and transformer T, heat radiation rack 2 and the circuit printing plate 3 that each circuit element is installed all are installed on wherein.
Preferred embodiment of the present utility model more than has been described, those skilled in the art can make variations and modifications in view of the above, and unlikelyly exceed scope of the present utility model.
