Abstract

This design uses the pulse signal from the speed sensor of the car to illuminate the instrument panel and other operation buttons to emit high-intensity 3-color chip type LEDs (three primary colors of light, red, green and blue) to emit a specified color according to the vehicle speed. As a lighting device for the instrument panel, the existing light bulb or monochromatic light emitting diode is removed, and the red, green, blue, and three-color high-brightness LEDs are connected in series with the PCB of the instrument panel and the operation buttons. It is an instrument panel lighting device that creates multiple colors by applying a variable voltage to each color of LEDs.

Description

Speed-sensitive automotive dashboard lighting device {SPEED PERCEPTION COLOR ILLUMINATION}

The present invention relates to a lighting device for a vehicle instrument panel and various buttons and a method thereof, and more particularly, by supplying three primary colors of light to each terminal of a three-color high-brightness LED by varying the voltage according to a pulse signal proportional to the speed. The present invention relates to a device and a method designed to transmit a color to an instrument panel so that a driver can recognize the speed quickly.

Uses small bulbs or monochromatic LEDs (light emitting diodes) to illuminate the instrument panel and control buttons used in the past and present.

In the case of the existing light bulbs, the filament is broken and it is difficult to grasp driving information or the position of the operation buttons during the night driving, and it is cumbersome to replace the light bulb by removing the instrument panel when repairing it. Use to ensure visibility and long life.

The present invention uses the three-color (red, green, wave) high-brightness LED that guarantees the visibility and long life as described above to provide the driver with an appropriate instrument background color according to the speed so that they can recognize visibility, economic speed and speed. It is.

In order to achieve the above object, first, a controller for converting a pulse signal that is proportional to the speed of a vehicle into an electric signal to create each color and a three-color light emitting unit for emitting light are required.

According to the above-described devises, the vehicle speed can be determined to the extent of the vehicle speed only by the color of the instrument panel. For example, the economic speed of about 80 km section color lights in green and gradually increases the red color when the speed increases. It allows the driver to recognize the speed even at high speeds without being distracted by the dashboard. With the development of the current automobile technology, the speed of the vehicle is not high enough to recognize the speed unless the instrument panel is recognized.The device is designed to give a sense of speed even with the colors of the instrument panel and various buttons inside the vehicle even at low, medium and high speeds. To ensure safe driving.

High-brightness LED that is steadily evolving is needed for this design. Currently, LEDs that are rapidly growing and producing low-power high-brightness are being produced. Among them, three-color LEDs using three primary colors of light that can make natural colors are used for color display boards and other electronic devices. have.

With 4 terminals, 1 terminal can be made by combining GND (-) and 3 terminals by applying (+) power respectively.The 3 color LEDs are produced in various shapes, so choose the shape that can be used for instrument panel lighting. .

First, the vehicle dashboard has a vehicle speed pulse signal coming from the transmission.

In the past, there was a method of displaying speed using a cable, but nowadays, it is rarely used due to cable disconnection or shaking of the display needle.

As the speed increases as the controller converts the pulse signal on the instrument panel into an electrical signal, the voltage of the indicator needle also increases, indicating the speed. In this way, the inventive device also detects a pulse signal and gives an electric signal to each of the three colors of LEDs to create a color.

For example, when the vehicle is stopped and there is no pulse, power is applied to the three LED terminals.

When the lighting is made white and the pulse signal increases by 1Km, the blue LED power is gradually reduced to make the yellow color at low speed.Of course, when the color is changed from white to yellow, the middle colors are various but different colors are realized by the power input method of three terminals. This is an example because you can. Afterwards, reduce the red power supply to display the stable color of the green series by gradually reducing the red power supply near the medium speed or economic speed of 80 ~ 90km, and then gradually reduce the green color to create a reddish color to quickly express the movement of the vehicle in color. do.

As above, the three-color LEDs are connected in series by the quantity to be mounted and emit the same color.

When the vehicle is started, IG1 power is applied to the controller and when driving, the pulse signal of the vehicle speed sensor is input to the controller, and then, three colors (R, G, B) high-brightness LEDs are gradually blinked to the designated three variable output stages to create natural color lighting. .
