Description

Blinking and Reflective Safety Vest USING ELECTRO LUMINESCENCE}

The present invention relates to a flickering reflective safety vest using electroluminescence, and in particular, using an electroluminescence (ELECTRO LUMINESCENCE, hereinafter referred to as EL) element that consumes less power in order to prevent accidents caused by being unidentified at night. It relates to a safety vest to improve the safety by causing light emission.

In the past, a safety vest using a reflective tape, film, or vinyl material was used. The vest uses a 'reflective reflection effect', and there are products using LEDs (Light Emitting Diodes). There was a problem such as a lot of power consumption, the practicality is poor.

Accordingly, the present invention has been made to solve the problems of the prior art, and an object of the present invention is to provide an apparatus for improving the performance of the safety vest by using an EL element with low power consumption.

The configuration of the flashing reflective safety vest using the present invention electroluminescence for achieving the above object is attached to the outer surface of the mesh-type vest integrally configured to be easily worn on the front, rear and waist of the upper body, the switch is turned on When the light emitting unit for controlling the power supply so that it blinks, a plurality of EL elements flashing by the power supplied from the light emitting unit and the inner side of the waist are provided on both sides to be fastened to each other to the body of the vest Characterized in that it consists of a fixed hook fixed to the waist.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a simplified view showing the configuration of the flashing reflective safety vest using the present invention electroluminescence, attached to the outer surface of the mesh type vest integrally configured to be easy to wear on the front, rear and hull part as shown therein Light emitting unit 100 for controlling the power supply to blink when the switch 140 is turned on, and a plurality of EL elements EL1 flashing by the power supplied from the light emitting unit 100. ~ ELn) and the fixing hook 120 is provided on both sides of the inner side of the waist to be fastened to each other to fix the body of the vest to the waist.

As shown in FIG. 2, the light emitting unit 100 connects the other side of the first capacitor C1 having one side connected to the other side of the switch 140 through node 1 to node 2, and one side to node 2. The other side of the transformer HV connecting the other side of the connected first resistor R1 to node 3 and the other side of the second capacitor C2 connecting one side to node 3 to the base of the transistor Tr1. The emitter of the transistor Tr1 connecting the collector to node 2 is connected to the other side of the second resistor R2 connecting to node 3.

Referring to the operation of one embodiment according to the present invention configured as described above is as follows. First, the EL elements EL1 to ELn, which is an important means for achieving the object of the present invention is shown in FIG. As shown in FIG. 5, the wiring 160 is connected to each other by soldering (soldering, 150), and as shown in FIG. 5, only the light emitting part is inserted into the reflective paper 110, and the remaining part is covered with the shrink tape 140. It prevents the defects caused by the left and right movement and twisting of the EL element, and also prevents the sewing failure by giving a predetermined width (for example, 5 mm) to each of the left and right. Meanwhile, as shown in FIG. ) Is provided at both sides of the inner side of the waist portion to fix the body of the vest to the waist portion, and as shown in FIG. 2, when the switch 130 is not turned on, the power supply to the light emitting portion 100 is blocked. This is done Power is not supplied to the elements EL1 to ELn. The light emitting unit 100 receives power from a power supply source and maintains the voltage at 3 volts V to supply the EL elements EL1 to ELn. Control the transformer (HV). Although the present invention has been specifically shown and described with reference to a preferred embodiment, those skilled in the art will understand that various changes are possible without departing from the spirit and scope of the present invention. Accordingly, the present invention is limited only by the claims.

As described above, the flickering reflective safety vest using the inventive electroluminescence uses an EL element that consumes less power, thereby reducing the consumption of power supply and extending the replacement time of the battery, thereby increasing convenience in use.
