Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
A kind of car bulb switching device, including light intensity sensor, digital analog converter, micro controller, lighting control circuit and
The alarm set prompted by word.
The light intensity sensor is electrically connected by digital analog converter and micro controller, before the light intensity sensor detection automobile
The light intensity weak signal of side, and it is sent to digital analog converter, light intensity weak signal is converted to digital signal by the digital analog converter, and
It is sent to micro controller.
The lighting control circuit includes triode, diode and relay, base stage and the micro controller electricity of the triode
Property be connected, the collector of the triode is electrically connected with relay, the emitter ground connection of the triode；The diode is simultaneously
The both ends of relay are associated in, the cathode of the diode is connected to vehicle power supply, plays the role of protective relay as a result, prevents
Only relay disconnects suddenly, causes breakdown；The normally opened contact of the relay is connected to the dipped headlight of automobile, the relay
Normally-closed contact be connected to the high beam of automobile, the high beam and dipped headlight are connected with vehicle power supply；
The alarm set includes the display screen and laser projection component being arranged in headstock, the display screen and projecting subassembly
It is electrically connected respectively with micro controller, the display screen informs that carrying out vehicle is changed by showing word, such as " switching dipped headlight "
Lamp；The projecting subassembly includes that the storage groove in headstock, laser generator and projection eyeglass is arranged, and the laser generator is red
Ray laser generator is located in storage groove and is electrically connected with micro controller, before the projection eyeglass is located at laser generator
Side, the projection eyeglass are the convex lens for capableing of astigmatism, and projection lens' on piece is equipped with the prompting that can be shown through laser projection
Word, i.e. word segment cannot be passed through by infrared light, such as the principle of projection pen now, such as " switching dipped headlight ", and laser is saturating
Projection eyeglass is crossed, the word for projecting eyeglass can be shown on the glass of front vehicles, the laser generator is arranged in vehicle
