It includes a field effect transistor (FET1) for controlling the on / off switching LED 50 according to the operation control signal to be,

The microcomputer 100 includes a key signal discrimination unit 110 for determining a key signal input from the lighting lamp key 10 and a reference for the on operation of the LED 50 according to the input signal of the lighting lamp key 10. The key signal is determined within a predetermined reference time by comparing the reference time set by the reference time setting unit 120 and the key signal determined by the key signal discriminating unit 110 with the reference time setting unit 120. It is characterized in that it comprises a lamp lighting determination unit 130 for outputting the operation control signal to the gate of the field effect transistor (FET1) by determining whether a predetermined number of times or more has occurred.

The lamp lighting control device of the present invention enables the LED key 50 to be turned on in accordance with a predetermined lamp lighting condition by inputting the key signal, so that the lighting lamp key 10 is turned on as it is pressed regardless of the user's intention. In order to prevent unnecessary battery consumption,

The lamp lighting control device according to the present invention uses a high brightness LED 50, and uses a field effect transistor (FET1) as a voltage switching element as its switching means.

As the user presses the lighting lamp key 10, the microcomputer 100 recognizes such a signal and accordingly supplies a driving voltage to the gate of the field effect transistor FET1 to turn on the LED 50.

The key signal discrimination unit 110 determines the input signal of the illumination lamp key 10, and the lamp lighting determination unit 130 sets the number of times set for the predetermined time set by the reference time setting unit 120 (Example 2 It is determined whether a key input signal has occurred.

When the key signal determination unit 110 determines the key signal input as in C2, the lamp light determination unit 130 performs the next key signal input during the reference time T1 set by the reference time setting unit 120. Will count up.

That is, as in the C2 waveform, when the first high (high) is input, the next high input time (T2) is within the reference time (T1) set by the reference time setting unit 120, the lamp lighting determination unit In operation 130, the LED 50 is turned on by outputting the gate driving voltage of the field effect transistor FET1 such as C3.

Thereafter, when the key signal input unit 110 receives the key signal input, the gate driving voltage of the field effect transistor FET1 is lowered again to turn off the LED 50.

However, as shown in FIG. 9, when the time T2 between inputs of the key signal is longer than the reference time T1, the gate driving voltage does not occur, and thus the LED 50 does not operate on.

In summary, the LED 50 can be turned on only after being input twice, for example, within a predetermined time, so that the LED 50 can be turned off with one touch. It is.

In this case, when the key button is pressed in a pocket or a bag, it is possible to prevent the lighting lamp from being turned on unnecessarily.

In another embodiment, the reference time setting unit 120 sets a reference time for the time that the key is pressed, and the lamp lighting determination unit 130 compares the time when the illumination lamp key 110 is pressed and the reference time. Therefore, the LED 50 can be turned on by generating the gate driving voltage of the field effect transistor FET1 only when the key is input for a predetermined time or longer.

Examples thereof are shown in FIGS. 10 and 11.

As shown in FIG. 10, when the key signal input T2 is performed for more than the reference time T1, the gate driving voltage of the field effect transistor FET1 is generated to turn on the LED 50, and as shown in FIG. 11. Similarly, when the key signal input T2 stops within the reference time T1, the gate driving voltage of the field effect transistor FET1 is not outputted, so that the LED 50 is not turned on.
