Description
Field of the Present Invention
The present invention relates to an illuminate warning vest with photo diode affixing structure, and more particularly to an illuminate warning vest that has a photo diode affixing structure which can safely secure the photo diode on the illuminate warning vest, so that the illuminate warning vest can be wore to make oneself noticeable to others either during a vehicle break down, or for the construction worker on the road.
Background of the Present Invention
Normally when a vehicle breaks down or has trouble on the road, the driver often try to alert the oncoming traffic to avoid accident by placing a light reflecting triangular warning sign, a warning cone, or a smoke flare behind the troubled vehicle. However, no device is yet designed to alert other drivers where the position of the driver of the troubled vehicle is. During night time, the night vision is often considerably poor. The driver of the break down vehicle would need to step out of the vehicle to place the warning device or walk in to the emergency phone, but since the driver is not easily noticeable, many unfortunate accidents happened during such process each year.
The road construction workers currently have special vest to help themselves being noticeable. The vest that they wore is made of bright color such as yellow or orange, and has many strips of light reflector sewed thereon. Most of the road constructions take place during night hour, because that is the time that has the lightest traffic. However, during night time, the vest that the road construction workers wore can not necessary bring instant attention from other drivers on the road from distances. If the drivers on the road can not see the road construction workers with enough reacting time, the life of the construction workers might be in serious danger, in other word, to bring instant attention to the drivers on the road from distances can avoid many accidents and definitely save life.
Summary of the Present Invention
The main objective of the present invention is to provide an illuminate warning vest with photo diode affixing structure which not only provides a light reflecting layer, but also comprises a plurality of build-in self flashing illuminating units to alert the oncoming traffic in high visibility during either day time or night time to fully provide warning and bring instant attention to other drivers on the road even from far away.
Another objective of the present invention is to provide an illuminate warning vest which is designed for the road construction workers to be highly visible and that can bring instant attention from other drivers on the road from far away.
Still another objective of the present invention is to provide an illuminate warning vest which provides an independent water sealed portion as a protective layer so that in case a defect or damage to a transparent water resistant layer, the water can not enter the illuminate warning vest to affect the proper function of the photo diode.
According to the present invention, an illuminate warning vest comprises an inner layer, a light reflecting layer, a transparent water resistant layer, a circuitry main board, a photo diode welded on the circuitry main board, and a protective case is engaged on the circuitry main board for protecting the photo diode, wherein the light reflecting layer has provided a plurality of through holes at a predetermined location, the circuitry main board is positioned between the light reflecting layer and the inner layer, two end portions of the circuitry main board have provided a plurality of symmetrical wire holes for allowing a wire to pass therethrough and electrically weld on an electrical conducting region of the circuitry main board.
The protective case has a center opening and comprises a plurality of affixing clips extended downwardly from a rim portion of the protective case. The affixing clips each has a clip end portion in a wedge shape. The circuitry main board further provided a plurality of welding holes at a center portion for allowing a terminal end of the photo diode to insert therein and weld on the electrical conducting region of the circuitry main board, and a plurality of affixing holes surrounding the plurality of welding holes for the clip end portion of the affixing clips of the protective case to engage therein.
The protective case is connected to the circuitry main board by engaging the clip end portion of the affixing clip within the affixing holes of the circuitry main board through at least a flange and the through hole of the light reflecting layer, so that the flange and the circuitry main board affixed the light reflecting layer therebetween; the protective case is safely covered the photo diode, in fact, a rim portion of the center opening of the protective case is pressed against a top portion of the photo diode, so that the photo diode is affixed in position and that the light spread out from the photo diode can be detected through the center opening and the transparent water resistant layer.
