させることができる。In the lamp configured as described above, when the lamp is to be turned on, all of the light emitting diodes 111 to 1 nm are made to emit light, and the lamp is turned on. At this time, by selecting an appropriate light emitting diode and setting the selected light emitting diode in a different state from the other light emitting diodes, for example by changing the brightness to add contrast, a message can be displayed in the lamp. . This message can be displayed as either letters or figures depending on the combination of light emitting diodes selected, and by displaying the message in the lamp in this way, it becomes more realistic than simply lighting or blinking. - You can also increase the types of expressions you can express.

A display state is shown in which 122 of these areas are displayed particularly brightly, and the remaining areas are displayed at brightnesses that are different from this brightness. FIG. 8 shows waveforms of signals supplied to each light emitting diode and the light emitting state of each light emitting diode in order to display the display shown in FIG. 7. Light emitting diode 11'1-13

る必要がある。The above is an example of using the same color but changing only the brightness to draw attention to the emitting part. However, the light emitting diodes that display characters or figures and the other light emitting diodes are colored in complementary colors or with eye-catching colors. It is also possible to create a contrast between the colors of the relationship such as this to make the characters or figures to be displayed stand out. In this case, color control can be performed by the method shown in FIG. In the same figure, Q
1 to Q4 are transistors, R1 and R2 are resistors, and D is a light emitting diode. The light emitting diode D includes a light emitting diode D1 that emits red light and a light emitting diode D2 that emits green light, which are connected in antiparallel and sealed in one case. Note that FIG. 9 shows the light emitting diode 1 in FIG.
Only the circuit for one light emitting diode numbered 1a to 190 is shown, and the other light emitting diodes must be constructed in the same way.

．． When the signal shown in FIG. 10(a) is supplied to Q2, and the signal having the waveform shown in FIG. 10(b) is supplied to transistors Q3 and Q4, the light emitting diode D emits light as follows. First, during the period indicated by T1 in FIG. 10, the transistor Q1,
Since the signal is supplied only to Q2, the transistor Q
1, Q2 is turned on, transistors Q3 and Q4 are turned off, current flows only to the light emitting diode D1, and the light emitting diode D emits red light.

オードＤは赤に近い黄色に見える。During the period T2, a signal is supplied that makes the on time of the transistors Ql and Q2 longer than the off time, and the transistor Q3. Q
Since transistors Q3 and Q4 are supplied with a signal having an opposite phase to that of transistors Q1. The on/off timing is opposite to Q2, and the off time is longer than the on time. For this reason, transistor Q1. When Q2 is on, the light emitting diode D1 emits red light, and the transistor Q3. When Q4 is on, light emitting diode D2 emits green light, and this state is repeated. For this reason, red and green light are emitted alternately, but if this repetition period is made shorter than the afterimage time of the eye, the red and green will be mixed and appear yellow, but the red light is emitted for a longer period of time. The light emitting diode D appears yellow, close to red.

。During period T3, transistor Q1. Although the phases of the signals supplied to Q2, Q3, and Q4 are opposite, the ON times are set to be the same, so the light emitting diode emits red and green light alternately with the same brightness. , Therefore, the light emitting diode D appears yellow. Also, contrary to period T2, the red and green light emission times are set to be long, so
The light emitting diode D appears yellow, which is close to green, and during the period T5, the light emitting diode D is controlled so that it emits only green light.
