DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment when the present invention is used in a mobile phone will be described with reference to the drawings. FIG. 1 is a rear external perspective view of a telephone device to which the present invention is applied. In FIG. 1, an antenna 120 for transmitting and receiving radio waves is provided in a case 90 of the telephone device, and three LED elements are arranged inside the case. , A display unit and a numeric keypad (not shown) for displaying a telephone number (not shown) disposed on the surface opposite to the surface on which the antenna 120 of the housing 90 is disposed.
[0008]
FIG. 2 is a block diagram showing a circuit configuration of a main part of the telephone device of this embodiment. In FIG. 2, reference numeral 100 denotes a CPU which controls the entire apparatus.
[0009]
The transmission / reception unit 110 connected to the antenna 120 performs detection of radio waves and transmission / reception of radio waves, and when receiving a signal from the calling side, notifies the CPU 100 that an incoming call has been detected. Further, the telephone number data of the other party included in the signal received at the time of the incoming call is detected.
[0010]
The display unit 140 is composed of, for example, a liquid crystal display device, displays the other party's telephone number data input from the transmission / reception unit 110, and displays the telephone number and the like input by the user using a numeric key 151 of the input unit 150 described later. To do.
[0011]
The input unit 150 includes a call key used when calling the other party, a communication key used when disconnecting communication with the other party, and the like, and the light is emitted from the input of the telephone number or the LED. A numeric keypad 151 used when a user performs setting (incoming call setting) for changing the intensity and color of light.
[0012]
The storage unit 160 can store setting information such as the color and intensity of light emitted from an incoming lamp 130, which will be described later, which can be set by an input operation of the input unit 150 by the user. It is also possible to store the telephone number and setting information in association with each other.
[0013]
The lighting control unit 170 controls the intensity of light emitted from each LED (the red LED 131, the green LED 132, and the blue LED 133) of the incoming lamp 130 connected to the lighting control unit 170 by the CPU 100. It is possible to selectively emit only the LED that emits the above-mentioned color.
[0014]
Specifically, the lighting control unit 170 can change the intensity of light emitted from the LEDs 131 to 133 by changing the resistance value of the resistor connected to the cathode side of the LEDs 131 to 133. That is, when it is desired to reduce the intensity of light emitted from the LEDs 131 to 133, the resistance value of the resistor connected to the LEDs 131 to 133 is increased, and when the intensity of the light is increased, The resistance value of the resistor connected to the LEDs 131 to 133 is reduced.
[0015]
It is also possible for the user to select and change only the resistance value of the resistor corresponding to the LED whose light intensity is to be changed.
[0016]
FIG. 3 is a display example of the display unit 140 when the light emission color of the incoming call lamp 130 is set.
[0017]
Each side of the triangle is associated with the LEDs 131-133, respectively. And based on the relationship between each side and the resistance value of the resistor connected to the LEDs 131 to 133 according to the shortest distance to the pointer 180, the resistance value of the resistor is changed to change the light intensity of the LEDs 131 to 133. For example, when the three colors are to have the same light intensity, the position of the pointer 180 may be set to the center of the triangle as shown in FIG. 3A, and when only two colors are to be emitted, the position shown in FIG. It is only necessary to move the pointer 180 to the position shown in FIG. 2. In this case, red and green emit light with the same light intensity, and blue does not emit light. If it is desired to emit only one color, the pointer 180 may be moved to the position shown in FIG. 3C. In this case, only red light is emitted. Since each side is displayed in the same color as the emission color of the corresponding LED, for example, it is possible to confirm which side corresponds to which emission color even in the case of FIG. .
[0018]
Further, when only red light is emitted as shown in FIG. 3 (c), light per color is emitted as compared with the case where three colors are emitted with the same light intensity as shown in FIG. 3 (a). Strength becomes stronger. Therefore, it is desirable to set the resistance value of the resistor so that the apparent light intensity is substantially the same in the case of only one color and in the case of three-color light emission. In FIG. 3, R indicates red, G indicates green, and B indicates blue. Also, in this embodiment, in order to make it easier for the user to visually grasp the light intensity, the shortest distance from each side to the pointer is proportional to the area of the area connecting each end point and the pointer. It is displayed as if determining the intensity of light.
[0019]
The pointer 180 moves when the numeric keypad 151 is pressed. For example, the “1” key is upper left, the “2” key is upper, the “3” key is upper right, the “4” key is left, the “6” key is right, The pointer 180 can be moved by moving the “7” key to the lower left, the “8” key to the lower, and the “9” key to the lower right. Accordingly, when the user presses the numeric keypad 151, the pointer 180 moves to obtain the distance from each side to the pointer 180, and this distance, the distance from each side stored in the storage unit 160 in advance to the pointer, and this The relationship between the resistance values of the resistors connected to the LEDs 131 to 133 in the lighting control unit 170 at the time is checked, and the resistance values of the resistors in the lighting control unit 170 connected to the corresponding LEDs 131 to 133 are changed. Thus, the intensity of the light emitted from each of the LEDs 131 to 133 and the on / off control of the light emission are performed.
[0020]
In this embodiment, the light intensity is set according to the distance from each side of the triangle to the pointer 180. However, the shape is not limited to this, and for example, the outline of a circle or a sphere may be used. A polygon such as a square may be used. FIG. 4 shows an example in which a sphere outline is used.
[0021]
For example, when using a contour or polygon of a circle or sphere, it is difficult to obtain the shortest distance from the contour or each side to the pointer. For example, the area of the area composed of each side and the pointer 180 And the intensity of light may be changed according to the size, or the shortest distance from the vertex of the polygon to the pointer may be obtained, and the intensity of light may be changed according to the distance. Alternatively, the light intensity may be stored for each dot of the display unit, and the light intensity may be changed by identifying which dot the pointer is on.
[0022]
In this embodiment, the colors of the LEDs are three colors of red, green, and blue. However, the colors are not limited to these, and LEDs of other colors may be used.
[0023]
In this embodiment, the number of LEDs for adjusting the light intensity is three. However, the present invention is not limited to this.
[0024]
Also, for example, if light emission of two or more colors is necessary among three color LEDs, for example, if setting is made using a pentagon as shown in FIG. 5, a pointer to a position covering all areas with one color is used. Since 180 cannot be moved, light emission of two or more colors is always possible.
[0025]
【The invention's effect】
According to the telephone device of the present invention, the light intensity of the plurality of LEDs can be set at the same time, so that the desired emission color can be easily set.
