BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multicolor warning light, especially a multicolor warning light using a photodiode as a light source. The object of the present invention is to provide an easy-to-handle multi-function warning light that is mechanically and electrically connected only by being inserted into a holder.

[0002]

2. Description of the Related Art The applicant of the present invention filed Japanese Utility Model Application No. 114284 in 1991 with a multi-light type or multi-light type illuminator having one holder at the center of the illuminating part. We proposed a multicolor signal lamp that inserts and connects a multicolor new-color light emitting unit that contains a warning and switches its luminescent color according to the purpose.

[0003]

Originally, this kind of multi-light type or multi-light path type illuminator illuminates an article such as a tool or fishing tackle without shading and provides a stress applied to the tool and fishing tackle. In view of the above, the structure is robust and complicated for the holder and the lighting part, so it has the drawback of high manufacturing cost, heavy weight and high power consumption, and is not suitable for security use for a long time. Appropriate.

[0004]

Therefore, in the present invention, the holder of the above-mentioned multi-lamp type lighting signal lamp is simplified, and a slit for a lead wire from a switch is provided at the lower part of the holder. In this slit, the contact between the lead wire and the printed circuit wiring terminal passing through the lighting unit support is arranged, and the electrical and mechanical connection is completed simply by inserting the support into the holder. And succeeded in achieving the intended purpose.

[0005]

Accordingly, the multi-color warning light of the present invention can complete the mechanical and electrical connection only by inserting the printed circuit wiring of the photodiode isolated for each desired color into the holder as described above. At the same time, it is screwed and fixed to the funnel-shaped support portion by the color arrangement cover corresponding to the color of the divided diode, and acts so as not to be detached at all even by repeated swings of the warning light.

On the other hand, the lead wire in the slit is connected to the wiring from the photodiode printed circuit board on the contact in the slit, and a switch mechanism corresponding to the color arrangement, ie, 3
Depending on the situation, a warning can be made by switching to an appropriate color depending on the situation, and if necessary, if an incandescent bulb is attached to the end of the lighting unit, the other two-stage switch will be used. It can serve a purpose separate from the purpose of the color warning light, namely for normal lighting.

On the other hand, a red and blue bicolor cathode lead (19)
Depends on the contact (15) of the terminal (23) provided at the lower end of the slit of the support (10), and the battery (1)
2) The anode of the switch (17) which is in contact with the anode (17), and the switch mechanism cathode contact (27) via the other battery anode (18) and the lead (L2)
Connect to The contacts (24) and (25) of the anode leads (20) and (21) are bent and fixed along the upper part of the support slit only by a predetermined width as shown by (22).
Care has been taken to facilitate contact with the leads (L) and (L1) of the switch mechanism. On the other hand, a flange (16) is provided on the holder (11) to prevent wobbling of the support (10), and a screw (30) is formed on the upper part of the funnel-shaped support (7). Rarely, it is screwed into the light emitting unit cover (2) so that the electrical contact of the light emitting unit is not cut off and the cover itself is fixed so as not to fall off.

In operation of the multicolor warning light (1) of the present invention,
First, the cover (5) of the battery compartment (4) is removed to remove the battery (1).
After loading 2), the light emitting unit cover (8) is fully tightened to complete the electrical and mechanical connection, and then the switch mechanism (6) is slid in the direction (F) to turn on the red warning light. Move. The switch contacts (26) (27) are thus connected,
Lead (L)-Contact (24)-Red photodiode anode lead (20)-Red, blue photodiode cathode lead (19)
Establish a red light diode lighting circuit of-terminal (23)-battery (12)-lead (L2).

When switching to the blue LED warning light (B), the switch mechanism (6) is slid in the direction (F '), the contacts (28) and (27) are connected, and the lead (L) is connected.

An incandescent lamp illuminating section (W) can be further added to this polymorphic warning light, and it is possible to perform a dual role of a warning light and an illumination light.

As described above, a two-color warning light has been described as an example. However, if the incandescent lamp switch mechanism is a three-stage switch mechanism, for example, red, yellow, blue, or just one color is added.
It can also be a green three-color warning light, and as mentioned above,

[0016]

According to the construction and operation as described above, the multicolor warning light of the present invention press-fits the support of the light emitting portion into the holder of the funnel-shaped support portion which is detachably screwed into the battery chamber. By simply doing so, a lighting circuit for the warning light is formed, so that handling and repair is easy, and a three-color or four-color warning and illumination combined light can be provided by using two switch mechanisms.

Further, since the cover for covering the light emitting portion is made of a combination of two transparent plastic cylinders and gelatin paper, the cover is light and at the same time, is screwed with the funnel-shaped support portion to form the support. The body is strongly pressed into the holder, and the lighting circuit contact at the tip of the body is strongly joined to prevent accidents such as disconnection of the circuit and to completely prevent the cover from falling off due to swing. .
