Description

[Detailed Description of the Invention] The present invention relates to a rotating light whose light color can be freely changed depending on the purpose and use of a single rotating light.

Conventionally, revolving lights have been used as indicator lights, but in recent years, as the number of types of traffic lights has increased, there have been many cases in which several revolving lights with different colors are installed side by side in order to distinguish them by light color. Ta.

This invention solves the above-mentioned applications by freely changing the color of the light using a rotating light stand, solving the conventional problems of space, inconvenience, complexity, poor visibility, etc. that require multiple light fixtures to be installed side by side. Furthermore, it can emit unique colored light.

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

An opaque case 3 is fixed to the bottom of a colorless and transparent globe 1 via a flange 2, and a light bulb 7 is rotated around the circumference by a rotary light motor 6 via support legs 5 for fixing a board 4 inside the bottom. A rotating light composed of a reflecting mirror 8 and the like is provided on the substrate 4 and is erected.

A space is provided between the inner surface of the globe 1 and the case 3 and the outer periphery of the rotary light board 4, and a cylindrical guide 9 is provided upright from the bottom of the case 3 in this space. The cylindrical filter 10.10' is placed in the guide 9,
Place it outside.

When the filter 10 or filter 10' is not needed, it is housed in an opaque case 3, and when necessary, it is raised to the periphery of the rotating lamp and the rotating lamp light passes through the filter to emit a number of colors.

The elevating mechanism opening of the filter 10 is provided with bearings 11, 11 corresponding to each other on the lower surface of the substrate 4 and the inner bottom surface of the case 3, and supports the ends of the male threaded shaft 12, respectively.

A gear B13 is fixed to the lower part of this male threaded shaft 12 and meshed with a gear A15 fixed to the motor shaft of a lifting motor 14 fixed to the case 3.

Further, a cylindrical arm 17 is made to protrude from the side of the female threaded ring 16 fitted to the male threaded shaft 12, and this arm 17 is inserted and fixed into a hole 18 which is provided below the filter 10 and has approximately the same diameter as the cylinder of the arm 17. , the end of the arm 17 engages with a notch 19 provided in an inverted U shape in a direction parallel to the axis of the guide 9.

Next, the elevating mechanism C of the filter 10' has the same structure as the elevating mechanism opening, and a bearing 1 is mounted between the lower surface of the substrate 4 and the bottom inner surface of the case 3.
1', 11', a male screw shaft 12', a gear B13', a gear A15', a lifting motor 14', and a female screw ring 16' with an arm 17'. The filter 10' is inserted and fixed into a hole 18' provided below the filter 10' by passing through a notch 20.19' provided in an inverted U shape in a parallel direction.

In the figure, 21, 22, 21', 22' are female threaded rings 16.
These are a rise limit switch and a fall limit switch that stop the driving of the lifting motors 14, 14' when the switch 16' comes into contact with them.

To explain the operation of the present invention, when power is supplied to the lifting motor 14, the male screw shaft 12 rotates through the gear A15 and gear B13, and the end of the arm 17 of the female screw ring 16 fitted into the lifting mechanism opening of the filter 10 rotates. is engaged with the notch 19 of the fixed guide 9, so the female screw ring 1
6 rises, causing the filter 10 to rise.

When the (+X-) power supply to the lifting motor 14 is reversed, the male threaded shaft 12 is reversed, the female threaded ring 16 is lowered, and the filter 10 is therefore lowered.

When power is supplied to the lifting motor 14', the lifting mechanism C of the filter 10' moves up and down in the same manner as described above.

When power is supplied to the rotary light motor 6 and the light bulb 7, the light from the light bulb 7 is rotated and emitted in all directions by the rotation of the reflector 8. However, when the filter 10.10' is lowered, the colorless and transparent globe 1 is emitted. The lamp emits seven colored lights to the surroundings through the bulb. For example, if only the red filter 10 is raised, the red light is emitted to the surroundings, and if only the yellow filter 10' is raised, the yellow light is rotated and emitted. Shine.

By adding filters and lifting mechanisms, you can create red, yellow, green, blue...
Filter 10.10', 10'', 10'''・
. . . can be raised independently to emit a wide variety of colored lights, and a single rotating lamp can transmit various arbitrary monochromatic light signals.

Also, due to simultaneous rise of both red and yellow filters, simultaneous rise of red, yellow, and green filters, etc., two-color, three-color,
It is also possible to emit mixed colored light in a rotating manner, and it is also possible to raise the red filter fully and raise the yellow filter half way to produce strange rotating light, making it an eye-catching display and demonstration. It can be used for a wide range of purposes as a rotating light with completely new functions.
