Description

{ Color Control System of Car light }

The present invention relates to a color control system for a headlamp for a vehicle, and more particularly, to a vehicle that can prevent traffic accidents in advance by converting the color of light set according to the surrounding environment while the headlamp is turned on, and is easy to install in a vehicle It relates to a color control system for headlights.

In general, vehicle headlights (headlamps) are installed on both sides along the width of the vehicle in the front part to secure the driver's view when driving at night by receiving electricity through a wiring connected to the vehicle's battery, and fog lamps are installed below it.

In general, headlamps and rear combination lamps use bulbs as light sources, but bulbs have a short service life and low impact resistance, so in recent years, high-brightness LEDs with long service life and excellent impact resistance are used as light sources. there is a trend to

The heat dissipation mechanism of such a vehicle headlamp consists of an LED headlight that acts as a light source as a headlight, a heat sink for dissipating heat lost through loss in the process of converting electrical energy into light energy, and a heat sink for heat energy A heat dissipation fan is provided to reduce the temperature of the heat sink by discharging it through forced convection, thereby stably converting energy and extending the lifespan of the LED headlamp. For reference, the LED headlight includes a reflector that reflects the beam emitted from the LED headlight and a lens that irradiates the beam reflected from the reflector forward.

On the other hand, in the case of these headlights or fog lights, the driver could not adjust the color of the desired light depending on the road conditions, so it was necessary to adjust the color of the headlight while driving, or it was necessary to increase the proportion of the yellow color in foggy conditions. There was a problem in that safe driving could not be achieved because it was impossible to adjust the color depending on the situation.

Of course, as an example for solving this problem, Patent Registration No. 10-0699690 (Reference 1) has been proposed. This relates to a lighting device for a vehicle using an LED, comprising: an LED module circuit in which a plurality of LEDs of at least two different colors including white (W) are arranged vertically and horizontally; a key input unit or sensor input unit for inputting illuminance and color by color selection and number selection of LEDs for a desired use among the LEDs of the LED module circuit; an LED color controller that calculates the color and brightness of each LED in order to control the optimal lighting color according to the instruction of the key input unit or the sensor input unit; It consists of an LED power converter that converts and supplies battery power to drive the LED module according to a control signal input by the output signal of the LED color controller.

However, the lighting device of Reference 1 calculates the color and brightness of each LED in order to control the lighting color input from the LED color controller according to the instruction when the user inputs the desired color and illuminance into the key input unit or the sensor input unit. The operation method is cumbersome to use. In addition, the above structure has a problem in that the set state is continuously maintained unless the user changes the setting state of the LED color controller later.

Of course, in order to solve the problem of Reference 1, the present applicant has proposed Patent Registration No. 10-1964091 (Reference 2). This relates to an automatic vehicle headlight color conversion system, and a vehicle headlight equipped with white and yellow LEDs emitting white and yellow light, an atmospheric moisture detection unit that detects the atmospheric moisture condition outside the vehicle and outputs an atmospheric moisture detection value; , When the vehicle motion detection unit for detecting the movement of the vehicle and the atmospheric moisture detection value detected by the atmospheric moisture detection unit exceed the atmospheric moisture reference value and the vehicle motion detection unit detects the vehicle movement, the white LED is turned on It is composed of a control unit that turns on the yellow LED in order to secure a visible distance in this state.

However, since the system of Reference 2 has extremely limited information on the environment around the vehicle, it is necessary to further include a vehicle motion detection unit in addition to the atmospheric moisture detection unit, so the system configuration is complicated, difficult to install, and the system configuration cost is also increased. .

In addition, the system of Reference 2 has limitations in preventing accidents because it is impossible to control the color conversion of vehicle headlights according to the driving environment or areas where vehicle operation is required such as accident-prone sections or child protection areas.

In addition, in the system of Reference 2, even if information about the environment around the vehicle is collected, the driver cannot check the humidity of the air, etc., and the use of the detected information around the vehicle is also very limited.

The surrounding information provided by the location-based information providing device 60 can overcome the inaccuracy of the moisture detection value measured by the moisture detection unit 51 and the limitation of surrounding information collection, and the surrounding reference value is the vehicle in a specific section. It includes the permitted driving speed, whether there is an accident-prone section or a child protection area, the external humidity standard value around the vehicle, the temperature standard value, and the dust and carbon dioxide concentration standard values.

Of course, the sensing control module 50 is provided with a wireless communication unit 53 in order to receive the surrounding information provided from the location-based information providing device 60 . The wireless communication unit 53 is preferably configured with Bluetooth capable of short-range wireless data communication with the location-based information providing device 60, but in addition, if short-range wireless communication is possible, various wireless communication modules such as Zigbee can also be used.

According to this configuration, the control unit 52 turns on the first and second white LEDs 11 and 21 while power is supplied to the power supply unit B after the operation of the headlight button B1, and is detected by the moisture sensing unit 51. When the moisture detection value outside the vehicle exceeds the set moisture reference value, the first and second yellow LEDs 12 and 22 are turned on or the brightness is adjusted, and when surrounding information is received from the location-based information providing device 60 A control signal capable of illuminating the first and second yellow LEDs 12 and 22 or adjusting the brightness according to the set peripheral reference value may be output to the left and right drivers 30 and 40 .

In this case, the set peripheral reference value includes an allowable vehicle driving speed in a specific section, an external humidity reference value around the vehicle 1, a temperature reference value, a dust and carbon dioxide concentration standard value, and a range of accident-prone sections or child protection zones.

Accordingly, the controller 52 determines that the driving speed value of the vehicle 1 received from the location-based information providing device 60 exceeds the vehicle driving speed in a specific section, or the vehicle 1 is in an accident-prone section or child. When entering the protected area as well as when the external humidity, temperature, dust and carbon dioxide concentration around the vehicle 1 exceed the standard values, the left and right drivers 30 and 40 are controlled to control the first and second white LEDs ( 11 and 21) are turned on, and the first and second yellow LEDs 12 and 22 are turned on, or after the first and second white LEDs 11 and 21 are turned off, the first and second yellow LEDs ( 12, 22) alone, or by controlling the first and second white LEDs 11 and 21 and the first and second yellow LEDs 12 and 22 together to adjust color or brightness, or to control blinking .

The yellow LEDs 12 and 22 control the left and right drivers 30 and 40 so that the white and yellow light alternately turns on by repeating a series of turning on, so that pedestrians around the vehicle can see the vehicle (1). can be easily recognized, leading to accident prevention.

These first and second white LEDs 11 and 21 and the first and second yellow LEDs 12 and 22 are lit together to further increase the moisture reference value set by the moisture detection value outside the vehicle detected by the moisture detection unit 51 . It is preferable to control the left and right drivers 30 and 40 so as to operate even in excessive situations (eg, when heavy rain or impropriety occurs).

On the other hand, the first white LED 11 provided in the left headlamp 10 may adopt a structure in which three white LEDs are continuously arranged and the first yellow LED 12 is three yellow LEDs are continuously arranged. The second white LED 21 provided in the right headlight 20 may adopt a structure in which three white LEDs are continuously arranged and the second yellow LED 22 is three yellow LEDs are continuously arranged. have.

According to this structure, when the driving speed value of the vehicle 1 received from the location-based information providing device 60 is 0 to 10 km/h, which is the detection-stop level, the control unit 52 performs the first and second steps as a first step. So that only one of the three LEDs constituting the white LEDs 11 and 21 is lit to achieve weak white lighting, or only one of the three LEDs constituting the first and second yellow LEDs 12 and 22 is lit to produce a weak yellow light. When the driving speed value of the vehicle 1 is 11 to 80 km/h, as the second stage, only two of the three LEDs constituting the first and second white LEDs 11 and 21 are turned on to achieve intermediate white lighting. or only two of the three LEDs constituting the first and second yellow LEDs 12 and 22, respectively, so that a medium yellow light is made, and when the driving speed value of the vehicle 1 is 81 to 120 km/h In the third step, all three LEDs constituting the first and second white LEDs 11 and 21, respectively, are turned on to achieve strong white lighting or all three LEDs constituting the first and second yellow LEDs 12 and 22, respectively. By controlling the left and right drivers 30 and 40 so that strong yellow lighting is made by turning on the light, pedestrians around the vehicle can easily recognize the vehicle 1, thereby inducing accident prevention.

Furthermore, when the driving speed value of the vehicle 1 exceeds 121 km/h, the control unit 52 turns on all three LEDs constituting the first and second white LEDs 11 and 21, respectively, as a last step. At the same time, the first and second yellow LEDs 12 and 22 turn off all three LEDs, and after a set time (for example, 0.5 to 1 second) has elapsed, the first and second white LEDs 11 and 21 are formed, respectively. At the same time, all three LEDs are turned off and at the same time all three LEDs constituting the first and second yellow LEDs 12 and 22 are turned on by repeating the series of steps to turn on the left and right side lights so that the white and yellow lights are alternately turned on.
