    Solar car's turn signal and stop light for energy saving
    The present invention relates to a turnaround light and a stop light of a solar car for power saving, and in detail, a conventional filament type lamp has a problem in that it does not efficiently use limited electrical energy, thereby connecting a plurality of high-brightness LEDs in parallel and energy. Solar car's turn indicators and stop lights for power savings that can be advantageous in terms of saving space and space for bulb mounting and utilization.
    In general, a solar car is a solar-powered car instead of a commonly used fuel, and a heat collecting plate attached to a car is installed to convert solar energy into electric energy, and the solar energy obtained from the heat collecting plate is converted into electric and power energy to travel. It is a vehicle that is being researched and developed for the purpose of replacing the limited energy sources remaining on the earth and measures to prevent environmental pollution in Korea and other countries around the world.
    Therefore, the above-described solar cell uses limited energy generated from the solar cell of the heat collecting plate, and thus requires a device of components that minimize power consumption during driving and driving of the vehicle. It may be the biggest problem to drive and drive the vehicle for a long time by using.
    However, the direction indicator light and the stop light using the conventional filament not only sufficiently consume electrical energy as shown in a) of FIG. 1, but also require a large amount of power, thus eliminating the problem that the required power must be sufficiently larger than a predetermined value. I couldn't.
    That is, the filament-type direction indicators and stop lights used in the conventional solar car has a problem that can not use the limited energy efficiently as the required power and energy consumption increases.
    Accordingly, the present invention has been made to solve the problems described above, by replacing the direction light and stop light of the solar car using a conventional filament-type bulb with a plurality of high-brightness LED to reduce the energy required and advantageous space The purpose is to provide a device that is expected to be utilized.
    Therefore, in the present invention, a plurality of high-brightness LEDs that are turned on by only low power are connected in parallel and mounted in a conventional bulb position, and a switching unit controlled by a pulse width modulation (PWM) controller controls the high-brightness LEDs at a speed of 1/20 sec or more. It is characterized by being configured to efficiently expect the energy saving effect and the space utilization of the bulb mounting by switching.

    Referring to the drawings illustrating the configuration of the present invention for achieving the above object is as follows.
    The switching unit 20 is connected from the turn signal or stop light switch 130 for applying power, and the switching unit 20 is controlled from a pulse width modulation (PWM) controller 30 so that the switching unit 20 is To control the high-brightness LED 40, the high-brightness LED 40 is installed by connecting a plurality of in series and parallel to the bulb (filament) position of the conventional direction indicator or stop light, five in series connected in series By connecting five high-brightness LEDs 40 in parallel to install a total of 60 high-brightness LEDs 40, it is advantageous to utilize a bulb installation space or to secure a space, and lights up according to the control state of the switching unit 20. And turn off so that the function as a turn signal or stop light can be performed sufficiently.
    Actions and effects on the configuration of the present invention described above are as follows.
    In general, turn indicators and stop lights should be yellow and red and should be able to check whether the left and right lamps are lit at a distance of more than 30 meters before and after each, and the number of flashes will require about 60 to 120 cycles per minute. It is prescribed.
    In addition, the basic characteristics of the high-brightness LED are as follows.
    In addition, the characteristics and bulb configuration for each lamp is as follows.
    In addition, calculation of the series resistance value and power consumption of a bulb is as follows.
    ** Series resistance of bulb
    IF = (Vcc-nV F ) / R ---- R = (Vcc-nV F ) / I F
    R (serial resistance) = (12-5 * 2.1) / 20 = 75 ohms
    n: Number of series LEDs Vcc: Auxiliary supply voltage
    n t : Number of bulb configuration LEDs n R : Number of bulb configuration series resistors
    ** Power consumption calculation
    P (LED Power Consumption) = n t (V F * I F ) = 60 (2.1 * 0.02) = 2.52 W
    P (resistance power consumption) = n R (IF2 * R) = 12 (0.02 2 * 75) = 0.36 W
    Bulb Total Power Consumption = 2.88 W
    The turn signal lamp or stop light switch 130 serves to apply the applied power to the switching unit 20 according to the state of the switch, the switching unit 20 from the pulse width modulation (PWM) controller 30 The switching unit 20 serves to control the high-brightness LED 40 by inputting a control signal, the high-brightness LED 40 is a plurality of bulbs (filament) position of the conventional direction indicator or stop light As it is installed in series and parallel connection, it is controlled in accordance with the above-described specifications, and thus lights and turns off, thereby fully functioning as a turn signal or a stop light.
    Accordingly, the direction indicator light and stop light of the solar car using the device of the present invention can minimize the power consumption by the high-brightness LED installed in place of the filament, and can expect energy saving effect, and the advantage of securing space for bulb mounting is advantageous There is this.
