Abstract
The utility model relates to a signal indicating lamp of a motor vehicle, which is composed of a lamp body, circuit boards, a luminous diode, a three-terminal voltage stabilizer, a current limiting resistor, a voltage stabilizing diode, a filtering capacitor, a fuse, a sealing cover, a line bundle plug and a lampshade. The utility model is characterized in that the middle of each of the circuit boards is connected in parallel with matrixes and is welded with the luminous diode, and the circumference of each of the circuit boards is provided with the three-terminal voltage stabilizer, the current limiting resistor, the voltage stabilizing diode, the filtering capacitor and the fuse. Each circuit board is connected together by the line bundle plug, the sealing cover is arranged behind the lamp body, and the lampshade is arranged before the lamp body. The signal indicating lamp of a motor vehicle has the characteristics of brilliant color, high brightness, low power consumption, long service life and low failure rate, both supplies accurate signal indication for various operations when the motor vehicle advances, reverses, brakes, turns or runs in fog days, thereby, has good alarm function.
Description
Technical field: the utility model belongs to motor vehicle signal lamp, specifically the vehicle signal indicator lamp.
Background technology: at present, the vehicle signal light fixture, generally all constitute by lampshade, lamp body, filament bulb, bulb socket, the sort signal lamp in use, burn as light bulb filament, rust is gone up in the corrosion of bulb fragmentation, lamp socket, when the lamp chamber is advanced reasons such as ash and dust clay contaminated and caused signal lamp normally to show, very easily causes traffic accident.
Summary of the invention: the purpose of this utility model is to develop and a kind ofly can be timely and accurately provides signal indication light source for self-propelled vehicle, even be that brightness height, power consumptive province, fault rate are low, long service life has one or several light-emitting diode to damage, the energy-efficient vehicle signal indicator lamp that remaining light-emitting diode still can normal operation.Its technology contents is, the vehicle signal indicator lamp, constitute by lamp body, circuit card, light-emitting diode, three terminal regulator, current-limiting resistance, zener diode, filter capacitor, wire fuse, seal cover cap, wire harness plug, lampshade, it is characterized in that, incidence matrix is welded with light-emitting diode in the middle of the circuit card, be provided with three terminal regulator, current-limiting resistance, zener diode, filter capacitor and wire fuse all around, with the wire harness plug each circuit card is connected together, be provided with seal cover cap behind the lamp body, be provided with lampshade before the lamp body.Its principle of work, self-propelled vehicle is when the various signal of operation, power supply surely drops to signal voltage on the operating potential of light-emitting diode by three terminal regulator, by filter capacitor the clutter filtering is delivered to through current-limiting resistance restriction electric current again and to be made it luminous on the light-emitting diode, get back to power cathode through wire fuse again; When the fault that occurs when three terminal regulator caused puncturing, signal voltage rose up to protection voltage the time at zener diode, and zener diode conducting work and wire fuse formation loop play a protective role blown fuse.
The utility model is compared its advanced part and is with prior art, the vehicle signal indicator lamp, have photochromic bright-coloured, brightness is high, power consumptive province, fault rate are low, can promptly and accurately spend for self-propelled vehicle signal indication light source is provided, one or several light-emitting diode was damaged, remaining light-emitting diode still can normal operation characteristics, take the weak point that filament bulb is changed in normal maintenance thereby overcome existing motor vehicle signal lamp.
Description of drawings:
Fig. 1 cuts open structural representation for the utility model stereoscopic office;
Fig. 2 is the utility model circuit diagram;
Wherein: lamp body 1, wire harness plug 2, circuit card 3, light-emitting diode 4, seal cover cap 5, three terminal regulator 6, wire fuse 7, filter capacitor 8, zener diode 9, current-limiting resistance 10, lampshade 11.
The specific embodiment: the utility model is remake description further below in conjunction with accompanying drawing, circuit card 3, middle incidence matrix are welded with light-emitting diode 4, be provided with three terminal regulator 6 all around, current-limiting resistance 10, zener diode 9, filter capacitor 8 and wire fuse 7 connect together each circuit card 3 with wire harness plug 2, are provided with seal cover cap 5 behind the lamp body 1, be provided with lampshade 11 before the lamp body 1, more than just constitute the utility model.
