Abstract
The utility model discloses an automatic display detector of vehicle lights, which can be used for automatic detection of various vehicle display lights. An allochroic light emitting diode is connected with the cable run of the vehicle display light; the color change of the allochroic light emitting diode displays the working situation of the display light. The utility model is easy to mount, and drivers in the cab can detect the working situation of each display light at any time.
Description
The utility model is that a kind of power actuated vehicle light shows detector automatically, its principal character is that variable color light-emitting diode and automobiles indicator lamp circuit link, but the driver can be in operator's compartment understands whether normal operation of indicator lamp at any time by the indication of variable color light-emitting diode.
Many indicator lamps are arranged on the automobile, as rear blinker, brake indicating lamp.These indicator lamps do not have indicative function often owing to fault does not work, and the driver can't know at any time that in operator's compartment indicator lamp could normal operation, and especially this situation runs into through regular meeting on autotruck.
The purpose of this utility model be to provide a kind of simple and practical, be convenient to install, reliable operation, can detect the automatic demonstration detecting device that can various indicator lamps normal operation at any time.
Technical solution of the present utility model is, indicator lamp is connected with switch and is constituted a control indicator light circuit, the direct ground connection of the indicator lamp other end, it is characterized in that: two negative poles of variable color light-emitting diode are connected with two indicator lamps respectively, the positive pole of variable color light-emitting diode is connected with a resistance, the other end of resistance and positive source are connected, and a variable color light-emitting diode can detect two indicator lamps.
When two above indicator lamps of a switch controls, the diode of between switch and variable color light-emitting diode and indicator lamp point of attachment, connecting respectively, diode cathode connects switch.
The variable color light-emitting diode is made up of two light-emitting diodes of sending out different colours light, two positive poles of sending out the light-emitting diode of different colours light are linked together, constitute the positive pole of variable color light-emitting diode, the negative pole of the light-emitting diode of two different colours light constitutes two negative poles of variable color light-emitting diode, and two LED package of sending out the different colours light are in a transparent shell.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the stoplight stop lamp testing circuit figure that adopts double-pole single throw.
Fig. 2 is the stoplight stop lamp testing circuit figure that adopts common single switch.
Fig. 3 is Cornering Lamp testing circuit figure
Fig. 4 is the backplan and the front elevation of variable color light-emitting diode surface structure.
Principle of work of the present utility model is described in further detail in conjunction with the accompanying drawings:
