Description

Lighting system

technical field

The invention relates to a lighting system, in particular to a vehicle lamp system for vehicle lighting.

Background technique

Nowadays, light-emitting diodes have been used as the light source of the car lighting system. The traditional car lighting system includes a fixed position of the light-emitting diode and a reflector that cooperates with the light-emitting diode. The reflector is used to reflect the light emitted by the light-emitting diode to the outside of the car . Since the installation positions and angles of a single set of reflectors and light-emitting diodes are constant, the irradiation direction and distance of a single set of light-emitting diodes and reflectors are fixed. In order to realize the lighting system of the car lighting in different directions and distances in front of the car, it is necessary to fix and install multiple groups of light-emitting diodes and reflectors at different positions and angles.

In view of this, it is necessary to provide a vehicle light system capable of conveniently adjusting the lighting angle so as to illuminate different areas near and far from the road ahead of the vehicle.

A vehicle light system is used to provide vehicles with illumination for the road ahead. The vehicle light system includes a light emitting diode, a control motor and a reflector module. The control motor is connected to the reflector module in transmission. The reflector module The set includes a first reflector and a second reflector, the first reflector is used to reflect the light emitted by the LED to the second reflector, and the second reflector is used to reflect the light reflected by the first reflector To the outside of the vehicle, the angle of the reflector module relative to the light-emitting diode is changed by controlling the driving of the motor, thereby changing the direction in which the light emitted by the light-emitting diode is reflected by the first reflector and the second reflector and exits the vehicle.

In the vehicle lamp system of the present invention, since the control motor is connected to the reflector module in transmission, the angle of the reflector module relative to the light-emitting diode is changed through the drive of the control motor, thereby changing the light emitted by the light-emitting diode through the first The reflection of the first reflector and the second reflector emits in the direction outside the vehicle, thereby conveniently realizing the illumination of the far and near areas in front of the vehicle by the vehicle light system.

The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings.

Detailed ways

Please refer to FIG. 1 , a vehicle light system 100 provided in the first embodiment of the present invention for providing illumination to the road ahead of the vehicle is arranged at the front end of the vehicle, and includes LEDs 10 , control motors 20 and reflector modules. The mirror module includes a first mirror 30 and a second mirror 40 .

The light-emitting diode 10 is electrically connected with the storage battery in the vehicle, and the storage battery in the vehicle is used to provide power for it. The light emitted by the light-emitting diode 10 is relatively concentrated and hardly diverges, and the light intensity is uniform and the brightness is high.

The shape of the first reflector 30 is arc, and is used to reflect the light emitted by the LED 10 to the second reflector 40 . The first reflector 30 has a concave first reflective surface 31, the first reflective surface 31 faces away from the front end of the vehicle, and the first reflective surface 31 of the first reflector 30 faces the LED 10. Light direction. Specifically, the first reflective surface 31 of the first reflector 30 is disposed obliquely above the front of the LED 10 approximately 30 degrees.

The shape of the second reflector 40 is arc, and is used to reflect the light reflected by the first reflector 30 to the outside of the vehicle. The second reflective mirror 40 has a concave second reflective surface 41 , and the area of the second reflective surface 41 is larger than that of the first reflective surface 31 of the first reflective mirror 30 . The second reflective surface 41 is facing the front end of the vehicle and the first reflective surface 31 of the first reflector 30 , and the second reflective surface 41 is substantially directly above the light emitting diodes 10 .

The control motor 20 includes a rotating shaft 21 , and the first reflector 30 is drivingly connected with the control motor 20 through the rotating shaft 21 . When the rotating shaft 21 of the control motor 20 rotates, the angle of the first reflector 30 relative to the light-emitting diode 10 is changed accordingly, thereby changing the position where the light-emitting diode 10 shines on the first reflector 30, and then changes the position reflected from the first reflector 30 to the first reflector 30. The light path of the second reflector 40 . Therefore, by changing the angle of the first reflector 30 relative to the light emitting diode 10 , the distance of the illuminated area can be controlled, so as to realize the near and far illumination of the vehicle lamp system 100 . The light emitted from the vehicle light system 100 shown in FIG. 1 can reach a far area for illumination. As shown in FIG. 2 , when the angle of the first reflector 30 relative to the light emitting diode 10 is changed, the illumination of the near area of the vehicle light system 100 can be realized.

Referring to FIG. 3 , a vehicle light system 100a provided by a second embodiment of the present invention includes a light emitting diode 10 , a control motor 20 and a reflector module. The mirror module includes a first mirror 30 and a second mirror 40 . The first reflector 30 has a concave first reflective surface 31 . The second reflector 40 has a concave second reflective surface 41 . The control motor 20 includes a rotating shaft 21 .

The difference between the vehicle light system 100 a of the second embodiment and the vehicle light system 100 of the first embodiment is only that the second reflector 40 is drivingly connected with the control motor 20 through the rotating shaft 21 . When the rotating shaft 21 of the control motor 20 rotates, the angle of the second reflector 40 relative to the first reflector 30 is changed, thereby changing the position of the light reflected from the first reflector 30 to the second reflector 40, and then changing the light from the first reflector 30 to the second reflector 40. The second reflector 40 reflects a path outside the vehicle. Therefore, by changing the angle of the second reflector 40 relative to the first reflector 30 , the distance of the illuminated area can be controlled to realize the far and near illumination of the vehicle light system 100a. The light emitted by the vehicle light system 100a shown in FIG. 3 can reach a farther area for illumination. As shown in FIG. 4 , when the angle of the second reflector 40 relative to the first reflector 30 is changed, the illumination of the near area of the vehicle light system 100 a can be realized.

Certainly, the above-mentioned control motor 20 can also be simultaneously drivingly connected with the first and second reflectors 30 and 40 of the reflector module, so as to more conveniently and effectively control the light emitting directions of the vehicle light systems 100 and 100a.

In the vehicle light system 100, 100a of the present invention, since the control motor 20 is connected to the reflector module in transmission, the angle of the reflector module relative to the light-emitting diode 10 is changed by the driving of the control motor 20, thereby changing the light emission. The light emitted by the diode 10 is reflected by the first reflector 30 and the second reflector 40 and then projected out of the vehicle, thereby conveniently realizing the illumination of the far and near areas in front of the vehicle by the lamp system 100, 100a.

It can be understood that, for those skilled in the art, various other corresponding changes and deformations can be made according to the technical concept of the present invention, and all these changes and deformations should belong to the protection scope of the claims of the present invention .
