Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indicator lamp, and more particularly to an indicator lamp that emits light intermittently.

[0002]

2. Description of the Related Art Conventionally, there has been an indicator light which draws a visual attention by intermittent light emission in which light emission of a light emitting body such as a light bulb blinks at a predetermined interval. There is a rotation indicator light mounted on the FIG.
FIG. 1 is a schematic diagram for explaining a general rotation indicator lamp 100.

[0003] As shown in the figure, the rotary indicator lamp 100 includes a gantry 101, a bulb 102, a reflector 104, and a protective cover 105. The gantry 101 is for installing and fixing the rotating lamp 100 at the installation location, and is provided at a substantially central position on the upper surface of the gantry 101 so that the bulb 102 protrudes upward.

The reflecting mirror 104 is formed in a substantially hemispherical shape so as to cover a substantially half surface in the vertical direction of the light bulb 102, and is provided on the gantry 101 so as to be rotatable around the light bulb 102. The rotation is driven by a rotation motor 106 built in the gantry 101.

[0005] The rotation indicator 100 configured as described above.
In this case, the light emission of the light bulb 102 is intermittently emitted when the light bulb 102 emits light by energization and the reflecting mirror 104 rotates around the surroundings, so that visual attention can be called.

However, the light-emitting bulb 102 has a short light-emitting life time, and replacement work due to running out of a bulb is complicated. Further, both the electric bulb 102 and the rotary motor 106 consume a large amount of power and cause a rise in running cost.

[0007] Since the rotation motor 106 for rotating the reflecting mirror 104 must be provided in the gantry 101, the rotation indicator 100 as a whole becomes larger by that amount, and the size of the rotation indicator 100 is reduced. It was difficult.

Further, a mechanism for rotating the reflecting mirror 104 includes:
This may lead to an increase in cost such as an increase in the number of parts and an increase in the number of assembly steps, and may cause an operation failure due to vibration or the like.

In order to solve such a problem of the rotary indicator, various indicator lamps having a display operation similar to that of the conventional rotary indicator have been proposed. For example, the light bulb 102 and the rotation motor 106 of the rotation indicator 100 are abolished,
A plurality of LEDs are provided in a substantially cylindrical base in a circumferential direction, and some LEDs are blinked at a predetermined timing.
There is an indicator lamp that emits light by rotating the lighting of D sequentially so that the light is rotating.

According to this method, a display operation similar to that of the conventional rotary indicator lamp 100 using the electric bulb 102 and the rotary motor 106 can be performed, and the various problems described above can be eliminated.

[0011]

SUMMARY OF THE INVENTION However, LEDs
It is difficult to use as an indicator light that calls attention only by turning on the LED alone because the brightness is low by itself. Was secured.

[0012] However, the LED requires a dedicated circuit for lighting and a heat radiating plate for radiating heat generated due to light emission. Therefore, the accommodation space for accommodating them must be provided in the indicator light, and the overall shape of the indicator light is unnecessarily large and the weight is excessive.

As a result, various conditions are imposed, the place where the indicator light is provided is narrowed, it cannot be mounted at an arbitrary position, and the convenience as the indicator light is deteriorated. In addition, the wiring assembling work for electrically connecting all of the plurality of LEDs increases the number of assembling steps, resulting in an increase in cost.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an indicator light which can be assembled at low cost and is lighter than the conventional one.

[0015]

In order to solve the above-mentioned problems, an indicator lamp according to the present invention comprises a plurality of surface light-emitting members whose entire surface emits light when energized, and the plurality of surface light-emitting members are respectively provided at predetermined timings. Flashing control means for energizing.
Then, an electroluminescent element (EL) is used for the surface light emitter.

Therefore, the size and weight of the indicator lamp can be reduced by utilizing the characteristics of the EL, which has a thin shape and emits light without generating heat when emitting light, and can provide uniform light emission over the entire surface by energization. be able to. At the same time, wiring and assembling work can be simplified, the manufacture of the indicator lamp can be easily performed, and the cost can be reduced by reducing the number of assembling steps and the like.
