Abstract
The utility model provides a light regulator for automatically switching illumination lamps for motor vehicles without battery cells, comprising a power amplifier driving relay circuit. The power supply of the power amplifier driving relay circuit is supplied by a rectification circuit which is connected with the terminal of a generator; the base electrode of the power amplifier driving switch tube is connected with the power supply through a voltage-stabilizing tube and a limiting resistor; an illumination lamp whose rated voltage is lower than the operation voltage of the voltage-stabilizing tube is connected to the normally closed contact of the relay, and the illumination lamp whose rated voltage is higher than the operation voltage of the voltage-stabilizing tube is connected to the normally open contact of the relay. The utility model can automatically switch illumination lamps according to the high and the low voltages of the generator, with convenient operation and safe working.
Description
The utility model relates to a kind of no accumulator railcar in the running of driving engine high, low speed, produces the light self-adjuster of the different automatic switching light lamps of voltage height according to electrical generator.
At present, no accumulator railcar lighting lamp power is supplied with by electrical generator, when self-propelled vehicle turns round with different rotating speeds at its driving engine, the voltage difference that electrical generator produced adopts the lower lighting bulb of rated voltage, then when high-speed operation, the voltage height that electrical generator produces is with this lighting bulb of easy burn-out; If adopt the higher lighting bulb of rated voltage, then when low-speed running, the luminance shortage of illuminating lamp.Adopt two filament illuminating lamps though also have at present, palpus manual switchover, inconvenient operation.
Task of the present utility model provides a kind of no accumulator railcar in the running of driving engine high, low speed, and it is different to produce the voltage height according to electrical generator, the light self-adjuster of automatic switching light lamp.
Task of the present utility model is finished as follows, it comprises that a power amplifier drives relay circuit, the power supply that power amplifier drives relay circuit is by the terminals that are connected on electrical generator, provide through rectifying circuit, the base stage of power amplifier driving switch pipe is connected on the power supply through stabilivolt and current-limiting resistance, the illuminating lamp that rated voltage is lower than the stabilivolt operating voltage is connected on the normally closed contact of relay, and the illuminating lamp that rated voltage is higher than the stabilivolt operating voltage is connected on the relay normally open contact.
When the time of engine low speed of self-propelled vehicle, the voltage of electrical generator after rectification is lower than the stabilivolt operating voltage, and power amplifier drives relay and do not work, and the normally closed contact closure of relay, the rated voltage that connects on it are lower than the illuminating lamp work of stabilivolt operating voltage; When the motor car engine high-speed operation, its voltage is higher than the stabilivolt operating voltage, power amplifier drives relay circuit work, the relay adhesive, its open contact closure makes the rated voltage that connects thereon be higher than the illuminating lamp work of stabilivolt operating voltage, it is different to produce the voltage height according to electrical generator, the automatic switching light lamp, easy to use, safe and reliable.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is the electrical schematic diagram of no accumulator railcar light self-adjuster;
Fig. 2 is the outside drawing of no accumulator railcar light self-adjuster.
In Fig. 1, Fig. 2, this light self-adjuster comprises that a power amplifier drives relay circuit, the power supply that power amplifier drives relay circuit is by the terminals 1,2 that are connected on electrical generator, provide through rectification diode D1 and capacitor C 1 filtering, the base stage of power amplifier driving switch pipe T1, T2 is connected on the power supply through stabilivolt D2 and current-limiting resistance R, the illuminating lamp L1 that rated voltage is lower than stabilivolt D2 operating voltage is connected on the normally closed contact 3 of relay J, and the illuminating lamp L2 that rated voltage is higher than stabilivolt D2 operating voltage is connected on the open contact 4 of relay J.Usually chassics earth, i.e. terminals 1 shell of meeting sb. at the airport.When the high engine speeds of this no accumulator railcar turns round, the voltage that electrical generator sends will be higher than the burning voltage of stabilivolt D2, provide base current by current-limiting resistance R and stabilivolt D2 to combination switch pipe T1, T2, make T1, T2 saturation conduction, it is electric that relay line bag J is got, and relay contact J1 switches, and illuminating lamp L1 switched become illuminating lamp L2 work, capacitor C 2 inference eliminations make its power drive relay circuit working stability; When time of engine low speed, electrical generator sends the burning voltage that voltage is lower than stabilivolt D2, combination switch pipe T1, T2 end, relay line bag dead electricity, and relay contact J1 keeps or recovers illuminating lamp L1 and work, this device makes driving engine automatic switching light lamp in high or low speed running changes, automatically regulating had both guaranteed brightness of illumination, was difficult for burning bulb again, easy to use, simple in structure.
