Abstract
A monitor for the light of car features that a monitor link consisting of amplifier and display device is arranged between car light and power supply. The link is placed in the cab. The link enables a driver to accurately judge whether the automobile lamp works normally in a cab. Therefore, the method avoids the mischief of traffic accidents caused by the fact that the driving dynamics can not be truly reflected because the vehicle lamp is not on.
Description
The utility model relates to automobile lighting system.
Car light is that the driver expresses the dynamic language that travels to the external world, and existing automotive lighting circuit is through switch and power supply direct connection entirely.The driver can't know whether normal operation of each car light in operator's compartment, promptly car light damage or circuit is short, when opening circuit, the driver do not know, the result still can think and will drive a vehicle dynamically or sail direction in advance and utilize light to express away.In this case, the easiest generation traffic accident causes damage for the country and people's lives and properties.
The purpose of this utility model provides a kind of driver can accurately judge the whether monitor unit of normal operation of automobile lamp in operator's compartment.
Scheme of the present utility model is to realize like this.
Between car light and power supply, be provided with one by amplifier and the supervision link formed as the display device of amplifier load.This supervision link is contained in the operator's compartment.
Below in conjunction with accompanying drawing scheme of the present utility model is illustrated.
Fig. 1 is a schematic diagram of the present utility model; Figure two is the utility model embodiment scheme circuits.
P whereinOBe autobulb, be connected with the base stage of the amplifier T of colelctor electrode output that the resistance of bulb is as the upper inclined to one side value resistance of triode. RbAn end be connected with the base stage of triode, the other end links to each other with power supply E, as the lower inclined to one side value resistance of triode. RbResistance depend on the size of supply voltage E and lamp resistance and the type of triode, namely when supply voltage was connected, triode T can enter the amplification saturation state, the P that is connected with colelctor electrodeJBe the display device as amplifier load, it can be bulb, also can be light emitting diode. As needing between colelctor electrode and light emitting diode, to connect current-limiting resistance and Zener diode with light emitting diode.
Good effect of the present utility model is as follows
1. be conducive to utilize several seconds before the driver goes out car, whether full car light circuit is worked once checks comprehensively.
2. break down if any the car light circuit in the driving, i.e. certain car light plugged and not working, the driver can find immediately. Thereby avoid because car light works driving dynamically being obtained truly Reflection and cause the disastrous effect of traffic accident.
Be described in further detail below in conjunction with embodiment of the present utility model.
The utility model embodiment scheme circuit:
Because the car light left and right sides is symmetrical, show automobile right side car light Circuits System so implement two of illustrations.R wherein
C1, R
C2, R
C3Represent right front turn lamp respectively, right front wide lampet and the right big passing light of showing; R
C4, R
C5, R
C6Represent right back steering indicating light respectively, right back taillight and right back stoplight stop lamp.Their wattage is respectively P
C1=P
C4=P
C6=21W, P
B2=P
C5=5W, P
C3=40W.They are the upward inclined to one side value resistance of amplifier aerotron in the supervision link cooresponding with it.The aerotron of present embodiment is germanium tube, and power line voltage is 12 volts, and under this condition, each road monitors that the following inclined to one side value resistance in the link is respectively R
B1=0.12 Ω, R
B2=0.48 Ω, R
B3=0.06 Ω, R
B4=0.12 Ω, R
B5=0.48 Ω, R
B6=0.12 Ω.D among Fig. 2 prevents that reverse potential from puncturing the diode of aerotron.Its breakdown reverse voltage value should be greater than 50 volts.
K
0Be before the car a certain moment to be used for checking the only combined switch of normal operation not of full car light.When it was pressed, the bulb in the monitor lamp box (H) was all lighted, and illustrated that then each bus lamp is intact, and is promptly working properly; Extinguish as a certain bulb in the monitor lamp box, illustrate that then cooresponding car light damages or its circuit breaks down, thereby remind the driver in time to repair.Whether the monitor lamp in the monitor lamp box can also be reminded the driver will once open to turn off after the car light of lighting uses up.K among Fig. 2
1, be the car light open-close on-off.
Claims (3)
1, a kind of light monitor for vehicle is characterized in that being provided with one by amplifier and the supervision link formed as the telltale of amplifier load between car light and power supply.
2, according to the described light monitor for vehicle of claim 1, it is characterized in that said amplifier is collecting electrode output, automotive bulb resistance is as being worth resistance partially on the transistor base, value resistance is R partially down, and its span is decided by the size of power line voltage, lamp resistance and the type of aerotron.
3,, it is characterized in that said display device is bulb or light-emitting diode according to the described light monitor for vehicle of claim 1.
