【Example】

 FIG. 1 shows an embodiment of an instrument pointer according to the present invention. In FIG. 1, an instrument pointer 10 is arranged in a row along the longitudinal direction of a pointer main body 11 made of a material such as plastic, and is arranged inside the pointer main body 11. It is composed of one LED chip 12 and a second LED chip 13 disposed adjacent to each of the first LED chips 12 respectively.

The first LED chip 12 is divided into a plurality of groups divided along the longitudinal direction thereof, three regions in the case shown in the drawing, into groups of three, and the LED chips 12 of each group are divided into groups. They are connected in series and are connected in parallel so that each set has the same polarity, and both ends of which are connected to the power supply 14 by one input of the input terminal 15 and the switching input terminal 16. It is connected to the terminal 16a. Further, three second LED chips 13 are arranged in parallel with each of the first LED chips 12 of each set so as to have opposite polarities, that is, one side is connected to the input terminal 15. At the same time, the other side is connected to each of the input terminals 16a, 16b, 16c of the switching input terminal 16.

Here, the first LED chip 12 has an emission color of green, for example, and the second LED chip 13 has an emission color different from that of the first LED chip 12, for example, the green color of the first LED chip 3. On the other hand, the emission color is red. Further, the input terminals 16a, 16b, 16c of the switching input terminal 16 are respectively connected to the contacts 17a, 17b, 17c of the selection switch 17, and one or a plurality of contacts are selectively made conductive by switching operation. It can be punished.

The instrument pointer 10 according to the present invention is configured as described above, and in the normal state, the selection switch 17 makes only the contact point 17a conductive, so that the power source 14 passes through the input terminals 15 and 16a. When the power is supplied in the P direction in this manner, only the first LED chip 12 is caused to emit light, and the entire pointer body 11 in the longitudinal direction is illuminated, for example, in green.

Here, when an abnormality occurs, for example, when the speed of the vehicle exceeds the speed limit or when the amount of remaining fuel is low, the degree of abnormality is determined according to the state of the abnormality. When the speed is low, for example, when the speed is less than 10 km, the selection switch 17 makes only the contact 17a conductive so that power is supplied from the power source 14 in the reverse direction, that is, the N direction through the input terminals 15 and 16a. By performing the above, only the LED chip 13a of the second LED chip 13 is caused to emit light. As a result, only the region at the tip of the pointer main body 11 is illuminated by the second LED chip 13a, for example, in red. Here, as the degree of abnormality increases, when the selection switch 17 sequentially turns on the contact 17b and the contact 17c in addition to the contact 17a, the second LED chip 13b from the power supply 14 via the input terminals 15 and 16b, 16c. , 13c are also supplied with power, and the second LED chips 13b, 13c also sequentially emit light.

Thus, when the degree of abnormality is low, only the LED chip 13a is caused to emit light, and when the degree of abnormality is slightly high, the LED chips 13a and 13b are caused to emit light, and finally the degree of abnormality is the highest. When it is high, the LED chips 13a, 13b, 13c of all the groups of the second LED chip 13 emit red light, and when an abnormality occurs, the second LED chip 13 causes the second LED chip 13 Warning lights of different emission colors, for example, red, can be displayed, and the length of the warning display area increases depending on the degree of abnormality, and the longer the degree of abnormality, the easier the abnormal state. Will be visible.

In the above-described embodiment, the warning display of an emission color different from the normal one is configured to spread gradually from the region near the tip of the pointer main body 11 toward the root according to the degree of abnormality. However, not limited to this, for example, when the degree of abnormality is low, a warning is displayed only in the area near the base of the pointer body, and as the degree of abnormality increases, the warning display is displayed at the tip of the pointer body. It is clear that any light emission pattern can be adopted as long as the light emission pattern for warning display changes according to the content of the abnormality. ..

[0015]

[Effect of the device]

 As described above, according to the present invention, the first LED chip is normally made to emit light to illuminate the entire length of the pointer main body in the longitudinal direction, but when an abnormality occurs, depending on the content of the abnormality, By causing only the LED chips of the predetermined selected group to be emitted from each group of the second LED chips, the pointer main body is illuminated with different emission colors by a plurality of types of emission patterns. Therefore, since the entire pointer body is illuminated with a plurality of types of patterns, a plurality of types of warning displays indicating the details of the abnormality can be displayed by the patterns. Thus, according to the present invention, when an abnormality occurs, a warning display of a different emission color from the normal time is displayed, and a warning display of a plurality of types of light emission patterns can be performed depending on the content of the abnormality. Excellent instrument guidelines are provided.
