Description

[Detailed Description of the Invention] The present invention relates to a lighting device for a rack installed in an automobile for mounting audio equipment such as a tuner and a cassette deck.

Conventional audio equipment racks for automobiles have been thought to only have the function of mounting a tuner and cassette deck, and generally do not have a lighting function.

As a prior art, a rack with a lighting function has been realized, but in this prior art, the lighting function was only provided to improve operability when installing a tuner or cassette deck on the rack at night.

Therefore, if we create a lighting device that can change the lighting color and brightness arbitrarily, it will be possible to increase the product value and make operating audio equipment more enjoyable. It will be possible.

The present invention was developed based on the above-mentioned viewpoints,
An object of the present invention is to provide a rack lighting device with variable lighting color and brightness.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of the present invention.

The rack 1 is attached to the lower part of a dash board of an automobile (not shown), and audio equipment such as a tuner 2, a cassette deck 3, a power amplifier 4, and an equalizer 5 are mounted thereon.

Illumination sections 6 and 7 are provided at the upper and lower portions of the front surface 1a of the rack 1, respectively, and the illumination color and brightness of each illumination section 6 and 7 can be freely adjusted.

FIG. 2 is a sectional view taken along section line II--II in FIG. 1.

The illumination units 6 and 7 are provided with lamps 10 and 11, respectively, inside a transparent cylindrical filter 8.9.

The filters 8 and 9 are rotatably provided around the axis over almost the entire width of the front surface 1a of the rack 1, and a part of the filters along the circumferential direction, for example, half the circumference, is provided along the front surface 1a.
It is exposed from a.

Moreover, each of the filters 8 and 9 is partitioned into a plurality of parts (two shown) along the circumferential direction, and these partitioned parts are colored in a plurality of colors, for example, red and blue.

For example, in the filters 8 and 9, red colored portions 8a and 9a and blue colored portions 8b and 9b are formed over approximately half a circumference.

Adjustment knobs 12 and 13 are rotatably provided at the upper and lower sides of the front surface 1a of the rack 1 in the width direction (the right side in FIG. 1), respectively.
are concentrically connected to filters 8 and 9.

Therefore, by rotating the adjustment knobs 12, 13, the filters 8, 9 can be brought to any angular displacement position.

Therefore, the red parts B a , g a of the filters 8 and 9
The blue portions 8b and 9b can be arbitrarily positioned in the portions exposed from the front surface 1a of the rack 1, and the illumination color of the illumination units 6 and 7 is adjusted to red or blue accordingly.

FIG. 3 is an electrical circuit diagram including lamp 10.11.

A first switch 15 and a second switch 16 are connected in parallel to a DC power source 14 such as a power supply.

The first switch 15 is turned on in conjunction with a switch (not shown) for turning on the headlights of the automobile, and the second switch 16 is turned on in conjunction with an ignition switch (not shown).

A resistor 17 and a lamp 10.11 connected in parallel are connected in series to the first switch 15.

Further, a relay switch 18 is connected in parallel with the resistor 17.

Audio equipment 20 such as the tuner 2 and the cassette deck 3 is connected to the second switch 16 via a current detector 19 .

A relay coil 21 for driving the relay switch 18 and a diode 22 for surge voltage protection are connected in parallel to the current detector 19.

When the current detector 19 detects a current, the relay coil 21 is excited, and the relay switch 18 is made conductive accordingly.

In such an electric circuit, when the first switch 15 becomes conductive, both lamps 10.11 are energized and lit, but since the voltage is dropped by the resistor 17, the brightness is relatively weak.

Next, when each audio device 20 is operated, the current detector 19
The relay coil is excited by the output, and the relay switch 18 becomes conductive accordingly.

Therefore, resistor 17 is shorted and both lamps 10.1
1 is energized with relatively large power and becomes bright.

In this way, when the audio equipment 20 is operated, the lighting units 6 and 7 automatically become brighter.

In another embodiment of the present invention, as shown in FIG. 4, the brightness of the lamp 10.11 may be continuously varied by means of a variable resistor 23.

As yet another embodiment of the present invention, as shown in FIG.
) or the like may be used to detect the ambient brightness and control the amount of power energized to the lamps 10.11.

That is, a signal output from the photodetector 24 in accordance with the ambient brightness is given to the control means 25, and the control means 25 energizes the lamp 10.11 with a power inversely proportional to the signal.

In the above embodiment, the illumination parts 6 and 7 are provided at the upper and lower parts of the front surface 1a of the rack 1, but their positions are not limited.

Further, the lighting section may be single. - As mentioned above, according to the present invention, the audio equipment mounted on the rack can be illuminated in such a way that the illumination color can be freely adjusted and the brightness can be changed, thereby improving the product value. You can enjoy operating audio equipment.
