Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable signal light that is manually operated by an attendant at a road construction site or a parking lot, and more particularly to a portable signal light that drives a light emitting diode group with a battery power source.

[0002]

2. Description of the Related Art A portable signal lamp having a typical structure is provided with an intermediate housing having a substantially cylindrical shape, an elongated cylindrical transparent hood connected to one end of the intermediate housing, and the other end of the intermediate housing. And a cylindrical grip portion, a plurality of light emitting diodes built in the transparent hood, a battery built in the grip portion, and a control unit attached to a side surface portion of the intermediate housing.
A push button type power switch is attached to the outer surface of the control unit, and a drive circuit for blinking the light emitting diode at a proper cycle is mounted on a printed circuit board mounted on the inner surface of the control unit. And the light emitting diode are connected via this circuit.

As a general structure, the control unit is integrated with a plastic unit base. A drive circuit and a circuit in which a power switch is mounted are attached to the unit base, and a rubber push button member for operating the switch is attached. The rubber push button member has an appropriate sealing property and prevents water droplets from entering from this portion. The unit base itself is fitted and mounted in the recess of the intermediate housing, and is entirely adhered to the intermediate housing by an adhesive that also serves as a sealing material.

[0004]

In this type of portable signal light, since the power switch is frequently turned on and off, the failure of the switch is relatively likely to occur. However, in the conventional type, the base of the control unit including the power switch is entirely adhesively fixed to the intermediate housing, so it is impossible to repair or replace the failed switch, and if the switch fails, the entire device becomes unusable. Become.

Further, the base of the control unit is adhered and fixed to the intermediate housing by an adhesive that also serves as a sealing material to realize the drip-proof property of the equipment, but this structure is careful to obtain high drip-proof property. The adhesive must be applied evenly over the entire surface by simple operations. Therefore, there is a problem that the productivity of the bonding process is low. If the adhesion process is simplified, defective products with respect to the drip-proof performance are likely to occur.

Further, this kind of portable signal lamp is made more conspicuous by blinking the light emitting diode. However, depending on the situation and application, it may be preferable to make continuous lighting instead of blinking. However, the conventional portable signal lamp is only for blinking and does not have an operation mode for continuously lighting the light emitting diode.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to easily repair or replace the switch in the case of failure, and to prevent a high assembly process from being complicated. It is an object of the present invention to provide a portable signal lamp that can realize the drip property and that can continuously turn on the light emitting diode.
