Abstract
The utility model discloses an automobile courtesy lamp circuit device. The automobile courtesy lamp circuit device comprise a backlight board, a backlight board blue LED current-limiting resistor, a white LED current-limiting resistor, a filtering capacitor, a rectifier bridge, a transient suppressor and a white LED. After an external power supply accesses a circuit, the transient suppressor suppresses the damage of an instant high voltage to the circuit, then the rectifier bridge shapes a voltage coming from the front end and is connected with the filtering capacitor to filter and process the shaped voltage, thereby obtaining a stable output voltage. And then the white current-limiting resistor and the backlight board blue LED current-limiting resistor limit the currents of the backlight board and the white LED respectively. The automobile courtesy lamp circuit device of the utility model enables the illumination brightness to be improved, the power consumption to be reduced, the service life to be increased and the cost to be saved, and is uniform in luminescence.
Description
Technical field
The utility model relates to a kind of automobile component, particularly relates to a kind of automobile courtesy light circuit arrangement.
Background technology
The automobile courtesy light belongs to a kind of mechanical transport language, and it is for showing the driving condition of vehicle.At present, what the vehicle body courtesy light adopted is that bulb is luminous, and uniformity of luminance is not high, and brightness is little, and consumed power is large, and heating is large, and range of exposures is narrow, and the life-span is short, and cost is high.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of automobile courtesy light circuit arrangement, can improve brightness of illumination, reduces consumed power, increases useful life, and luminous even, cost-saving.
For solving the problems of the technologies described above, a kind of automobile courtesy light circuit arrangement that the utility model provides, comprise backlight, backlight blue led current-limiting resistance, White LED current-limiting resistance, filter capacitor, rectifier bridge, transient suppressor and White LED; External power source suppresses the infringement of instantaneous pressure to circuit by transient suppressor after entering circuit, then by rectifier bridge, the voltage from the front end transient suppressor is carried out to shaping, be connected to the voltage of filter capacitor after to shaping and carry out the filtering processing, thereby obtain stable output voltage, then by white current-limiting resistance and backlight blue led current-limiting resistance, respectively backlight and White LED are carried out to current limliting.
Preferably, also comprise cover pillar jack.
The utility model automobile courtesy light circuit arrangement, adopt the light source of blue led as backlight, sticks diffusion barrier on backlight, further improved luminous uniformity, under the leaded light effect of backlight, makes the character on lamp housing high-visible at night simultaneously.Use in addition White LED as the ground radiation source, on the basis of improving in brightness, provide cost savings, saved efficiency, for implementing national energy-conserving and environment-protective policy behave.The utility model makes and the perfect combination of original automotive internal bulb interface in order to alleviate the built-in rectifier bridge of facilitating of vehicle refitting, has saved manpower and materials; For the perfect protective circuit system of the built-in transient suppressor of the fail safe of circuit is without prejudice, adopt the current-limiting resistance current limliting to provide reliable operating current for LED, significantly utilize the characteristic of LED high life.Moreover, by the irradiation of 3 White LED multi-angles, irradiate area coverage and further enlarge, well improve original bulb irradiation narrow range shortcoming.Finally, due to long-term and light source close contact, LED is as light source, and the light of its emission is harmless.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1-2, automobile courtesy light circuit arrangement of the present utility model, comprise backlight 1, backlight blue led current-limiting resistance 2, White LED current-limiting resistance 3, filter capacitor 4, rectifier bridge 5, transient suppressor 6 and White LED 8; Described external power source suppresses the infringement of instantaneous pressure to circuit by transient suppressor 6 after entering circuit, then carry out shaping by 5 pairs of voltages from front end transient suppressor 6 of rectifier bridge, the voltage be connected to after 4 pairs of shapings of filter capacitor carries out the filtering processing, thereby obtain stable output voltage, then by white current-limiting resistance 3 and backlight blue led current-limiting resistance 2, respectively backlight 1 and White LED 8 are carried out to current limliting.Automobile courtesy light circuit arrangement of the present utility model can also comprise cover pillar jack 7, and described cover pillar jack 7 is reserved for cover column construction part.The utility model after passing into electricity, by backlight, the visual successful of the light guide effect character of diffusion barrier, by the multi-angle irradiation of led, range of exposures is large in addition, irradiation brightness is high.
The utility model adopts the light source of blue led as backlight, sticks diffusion barrier on backlight, has further improved luminous uniformity, under the leaded light effect of backlight, makes the character on lamp housing high-visible at night simultaneously.Use in addition White LED as the ground radiation source, on the basis of improving in brightness, provide cost savings, saved efficiency, for implementing national energy-conserving and environment-protective policy behave.The utility model makes and the perfect combination of original automotive internal bulb interface in order to alleviate the built-in rectifier bridge of facilitating of vehicle refitting, has saved manpower and materials; For the perfect protective circuit system of the built-in transient suppressor of the fail safe of circuit is without prejudice, adopt the current-limiting resistance current limliting to provide reliable operating current for LED, significantly utilize the characteristic of LED high life.Moreover, by the irradiation of many White LED multi-angles, irradiate area coverage and further enlarge, well improve original bulb irradiation narrow range shortcoming.Finally, due to long-term and light source close contact, LED is as light source, and the light of its emission is harmless, for the health of people's health, can not shine into any harmful effect, and this point is that other light sources does not possess.
Abovely by specific embodiment, the utility model is had been described in detail, but these not form restriction of the present utility model.In the situation that do not break away from the utility model principle, those skilled in the art also can make many distortion and improvement, and these also should be considered as protection range of the present utility model.
