BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-luminous warning display device which is used by a road worker or the like to display a warning on a bicycle, a car, or another vehicle when worn over clothes. is there.

[0002]

2. Description of the Related Art FIGS. 15 and 16 show an apparatus for preventing an accident caused by a passing vehicle or the like and ensuring the safety of workers during work such as road construction or patrol on a night road. As described above, a self-luminous warning display device 51 formed in a vest shape so that a user can wear the clothing 50 from above is proposed.

Many warning display devices 51 of this type have a plurality of chip-type light-emitting elements 53 serving as a light source arranged and fixed on the surface side of a flexible substrate 52, and the flexible substrate 5 is provided.
2 and the chip-type light-emitting elements 53, 53... Are covered with transparent resin waterproof sheets 54, 54, respectively.
A flashing device is connected to the chip-type light-emitting elements 53, 53,.

[0004]

However, in the above-mentioned conventional warning display device 51, the flexible substrate 52 and the chip-type light-emitting elements 53, 53... On the other hand, when the chip-type light-emitting elements 53 are turned on, the chip-type light-emitting elements 53 emit an irradiating light beam from inside the waterproof sheet 54 on the front side. ., The transmittance of the illuminating light flux of the chip-type light emitting elements 53, 53... Emitted through the waterproof sheet 54 is reduced, so that the luminance of the emitted light flux is insufficient. Of the warning display device 51, a wide-ranging irradiation effect in the up, down, left, and right directions of 180 ° in front of the display surface of the warning display device 51 cannot be obtained, and in particular, sufficient visibility in a state worn by the user can be obtained. It had a problem that can not be secured.

The present invention has been made in view of the above-mentioned problem, and uses a high-brightness light emitting diode formed by molding a light emitting chip with a so-called shell-shaped synthetic resin lens as a light source. The luminous brightness as a luminous type warning display device is improved, and the user can wear it over a wide area when wearing it over clothes or work jackets.
It is an object of the present invention to make it possible to irradiate in the 0 ° direction, to prevent glare from being emitted to the user, and to improve the visibility of the warning display device.

[0006]

In order to achieve the above-mentioned object, a plurality of light emitting diodes protruding from the surface side are fixed in parallel to a work confirmation band formed of a long and flexible sheet material. In addition, the gist of the present invention is to provide a protector that covers an outer peripheral portion of a lens light emitting portion of each light emitting diode, which is on an upper side when the work confirmation band is mounted, and has a light shielding edge for restricting upward emission.

A plurality of the light emitting diodes are fixed in parallel on a substrate, and the front and back surfaces thereof are covered with a front fabric and a back fabric formed of a waterproof sheet or the like. The portion may be protruded together with the light-shielding edge of the protector, and the protector may be integrally fixed to the substrate surface side.

Further, the light emitting diode can be constituted by integrally molding with a protector supporting the light emitting diode.

[0009]

According to the above-mentioned structure, when the light is turned on or off by being worn from the top of a worker's clothes or a work jacket, etc., a mold for a mold having a bullet-shaped light emitting diode projecting to the surface side of the work confirmation band is provided. 180 directly in front of the lens
The irradiation light beam is emitted in the ° direction to ensure wide visibility for the user. Further, since the light-shielding edge prevents the emission light beam from being emitted in the direction of the user's line of sight, the user is not dazzled by the emission light beam of the warning display device in use.
