Abstract
The utility model discloses a car headlight with spare lamp pearl, include: the main lighting circuit consists of a main LED lamp and a current detection module, wherein the main LED lamp is used for lighting, and the current detection module is used for detecting the current of the main lighting circuit; the standby lighting circuit is connected with the main lighting circuit in parallel and is provided with a standby LED lamp for standby lighting; the control main board is respectively connected with the main lighting circuit and the standby lighting circuit and used for receiving a signal of the current detection module to control the switching of the standby lighting circuit; and the storage battery is connected with the control main board in series and is used for supplying power.
Description
Technical Field
The utility model relates to a LED car light field specifically is a car headlight with spare lamp pearl.
Background
Currently, automobile headlamps have been developed to the fourth generation, the first generation of automobile light sources are directly burning by fuel to emit light; the second generation automotive light sources are incandescent lamps; the third generation automotive light source is a gas discharge lamp; fourth generation automotive light sources are semiconductor light emitting diodes. The LED car lamp has higher luminous efficiency than the common car lamp because the LED directly converts electric energy into light energy, and the bulb power consumption is only equal to 1/10 of the traditional lamp.
The automobile LED headlamp is high in current for ensuring good lighting brightness, the LED lamp beads have obvious heating phenomena and are extremely easy to burn out, so that the automobile LED headlamp usually has a radiating fan, but has a large burning risk when being used for a long time at night, and if the LED lamp beads are burnt out when driving at night, the automobile loses the lighting headlamp and has a high form potential safety hazard.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an automobile headlamp with spare lamp pearl.
The utility model provides a technical scheme as follows that above-mentioned technical problem took:
the utility model provides a car headlight with spare lamp pearl, includes:
the main lighting circuit consists of a main LED lamp and a current detection module, wherein the main LED lamp is used for lighting, and the current detection module is used for detecting the current of the main lighting circuit;
the standby lighting circuit is connected with the main lighting circuit in parallel and is provided with a standby LED lamp for standby lighting;
the control main board is respectively connected with the main lighting circuit and the standby lighting circuit and used for receiving a signal of the current detection module to control the switching of the standby lighting circuit;
and the storage battery is connected with the control main board in series and is used for supplying power.
When the automobile lamp is started, the main lighting circuit is driven by default to use the main LED lamp for lighting, when the main LED lamp is burnt out, the main lighting circuit is disconnected, namely the current detection module detects that the current of the main lighting circuit suddenly drops to 0, the control panel starts to switch and drive the standby lighting circuit, and lighting is carried out through the standby LED lamp.
Preferably, the automobile headlamp with the spare lamp beads further comprises a fault lamp, and the fault lamp is connected with the control main board. When the car light is in use, if the main LED lamp burns out, the main lighting circuit is disconnected and no current passes through, then the fault lamp is often bright, reminds the driver to change the maintenance car light.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
Drawings
The present invention will be described in detail with reference to the accompanying drawings so that the above advantages of the present invention can be more clearly understood.
Fig. 1 is a connection block diagram of the car headlight with the spare lamp bead of the utility model.
Detailed Description
The present invention will be described in detail with reference to the following specific embodiments.
As shown in fig. 1, an automobile headlamp with a spare lamp bead includes:
the main lighting circuit consists of a main LED lamp and a current detection module, wherein the main LED lamp is used for lighting, and the current detection module is used for detecting the current of the main lighting circuit;
the standby lighting circuit is connected with the main lighting circuit in parallel and is provided with a standby LED lamp for standby lighting;
the control main board is respectively connected with the main lighting circuit and the standby lighting circuit and used for receiving a signal of the current detection module to control the switching of the standby lighting circuit;
and the storage battery is connected with the control main board in series and is used for supplying power.
When the automobile lamp is started, the main lighting circuit is driven by default to use the main LED lamp for lighting, when the main LED lamp is burnt out, the main lighting circuit is disconnected, namely the current detection module detects that the current of the main lighting circuit suddenly drops to 0, the control panel starts to switch and drive the standby lighting circuit, and lighting is carried out through the standby LED lamp.
The LED automobile headlamp is taken as an example in the embodiment, the LED lamp bead is small in size, and the LED lamp for equipment does not have large influence on the size of the existing LED automobile headlamp.
Preferably, the automobile headlamp with the spare lamp beads further comprises a fault lamp, and the fault lamp is connected with the control main board. When the car light is in use, if the main LED lamp burns out, the main lighting circuit is disconnected and no current passes through, then the fault lamp is often bright, reminds the driver to change the maintenance car light.
The utility model relates to a car headlight with spare lamp pearl has set up spare LED lamp with, if main LED lamp burns out when the car goes at night, this car headlight passes through the main lighting circuit of current detection module automatic identification and opens circuit and switches to the illumination of spare lighting circuit, and the lighting condition who maintains the car is not influenced, very big guarantee the safety that the car went night.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
