[0003]

[Problems to be solved by the device]

 In the conventional lighting device of the heater control panel 1 described above, there are cases where it is desired to change the lighting color, but this lighting color is uniquely determined by the color of the color cap 5. Even if the color cap 5 is replaced with another color cap, it cannot be easily done.

In view of the above points, the present invention has an object to provide an illumination device of a heater control panel that can easily switch to a desired illumination color.

[0005]

[Means for Solving the Problems]

 An illumination device for a heater control panel according to the present invention includes a temperature display section for displaying a temperature controlled by operating a temperature control lever, a light source for illuminating the temperature display section, and a light source for guiding the light source to the temperature display section. A means for illuminating light is provided, but a filter guide equipped with a plurality of color filters is movably provided, and the filter guide and the temperature control lever are interlocked with each other to operate the temperature control lever to illuminate. The colors can be switched.

[0006]

[Action]

 According to this invention, the temperature can be controlled by operating the temperature control lever, but the filter guide moves in accordance with the position of the temperature control lever, that is, one of the plurality of color filters is used as the light source. Can be arranged correspondingly. Then, it is possible to obtain a desired illumination color through the color filter arranged corresponding to the light source.

【Example】

 An embodiment of the heater control panel lighting device of the present invention will be described below with reference to FIGS. 1 and 2 show the overall configuration of the lighting device of the present invention. In the figure, 1 is a heater control panel, 2 is a temperature display part, 3 is a knob, 4 is a light source bulb, 6 is a prism, and 7 is a control lever. The control lever 7 is rotatably supported around its support shaft 7a.

Reference numeral 8 denotes a filter guide, which is supported so as to be movable along the rotation direction of the control lever 7 (the left-right direction in FIG. 1). Reference numeral 9 is a pin implanted in the control lever 7 and moves along with the control lever 7, and its movement locus 9a is shown in FIG. As shown in FIG. 3, the pin 9 is adapted to be inserted into the guide frame 8a of the filter guide 8 and abuts against the end portions 8a ₁ and 8a ₂ of the guide frame 8a.

Reference numeral 10 denotes a plurality of color filters mounted on the filter guide 8. In the present embodiment, a red (R) color filter 10 a, a green (G) color filter 10 b, and a blue (B) color filter 10 a. It is composed of a color filter 10c. The control lever 7 rotates in the range of COLD _max to HOT _max as shown in FIG. 1 in order to perform the temperature control of the cold and warm, and the filter guide 8 is interlocked with the control lever 7 via the pin 9. Thus, the color filters 10a, 10b and 10c are set according to the position of the control lever 7.

Next, the operation of the heater control panel lighting device of the present invention will be described. In FIG. 4 (A), when the control lever 7 is at the position W ₁ (COLD _max ) and the pin 9 is in contact with the end portion 8a ₁ of the guide frame 8a, the color filter 10c with respect to the light source bulb 4 is placed. Is set. In this case, a blue illumination color is obtained. Then, the blue state is maintained until the control lever 7 is rotated to the HOT side and the pin 9 comes into contact with the end portion 8a ₂ (position W ₃ ).

When the control lever 7 is further rotated from the position W ₃ to the HOT side, the pin 9 pushes the filter guide 8 to set the color filter 10b. Then, as shown in FIG. 4B, the illumination color is switched to green at the position W _3.5 .

When the control lever 7 is further rotated to the HOT side, the color filter 10c is set similarly to the above, and the illumination color is switched to red (FIG. 4 (C)). The illumination color can be switched by rotating the control lever 7 as described above. However, when the control lever 7 is rotated from the respective positions to the COLD side contrary to the above, the pin 9 is guided. The illumination color being switched is held until it comes into contact with the end 8a ₁ of the frame 8a.

FIG. 5 shows the relationship between the position of the control lever 7 and the illumination color. As long as the control lever 7 is operated within a fixed rotation range, the illumination color at that time can be maintained. In FIG. 5, the positional relationship of the temperature display section 2 is also shown, but in actual use, the range of use of the control lever 7 is normally set to the COLD side (Ws) in summer and in winter. It is set on the HOT side (Ww). Therefore, for practical use, for example, a warm red color is used in winter, a cold blue color is used in summer, and a green color is used in spring and autumn between them. You can get it.

In the above embodiment, an example in which the temperature is controlled by the control lever 7 has been described, but as shown in FIG. 6, it is also applicable to a dial type. In this case, the temperature display section 12 is arranged along the circumference of the temperature control dial 11. However, by providing a plurality of color filters in the circumferential direction so as to correspond to the temperature display section 12, the above-mentioned embodiment is realized. Similar effects can be obtained.

[0015]

[Effect of device]

 As described above, according to the present invention, in this type of illumination device, it is possible to easily switch to a desired illumination color, and it is possible to produce a desired illumination effect in accordance with the sense of season, for example. Moreover, it is possible to switch the illumination color with a simple structure without providing a large number of light source bulbs or changeover switches, which is advantageous in terms of cost.
