Background of the Present Invention Normally when a vehicle breaks down or has trouble on the road, the driver can place a conventional triangular light reflecting warning sign behind the troubled vehicle for alert warning. The conventional light reflecting triangular warning sign work fine during daytime or high visibility hours. However, when the weather is rainy or foggy, with low visibility other drivers may fail to observe the warning sign and crash into the troubled vehicle.

The conventional light reflecting triangular warning sign also have the following shortcomings. Most of the conventional light reflecting triangular warning sign is not easy to store because of their sizes. Although the size of the conventional light reflecting triangular warning sign seem too large to fit well in the trunk of the vehicle, when they are placed on the road, they becomes too small to catch the attention of other drivers. The earlier the other drivers can detect the bad road condition ahead, the more reaction time the other drivers may have to avoid the accident.

Another major disadvantage of the conventional light reflecting triangular warning sign is that it do not provide the self-flashing or self-illuminating function. As mentioned above, during low visibility condition, such as the bad weather condition or nighttime, other drivers may not be able to clearly observe the warning signs that would lead to an undesirable accident.

Summary of the Present Invention The main objective of the present invention is to provide an illuminant triangular warning arrangement, which not only provides a light reflector device, but also comprises a plurality of build-in self-flashing illuminating units to alert other drivers in high visibility, during either day time or night time, to provide safety protection for the drivers and the troubled vehicle. Moreover, the illuminating units are specifically designed to bring instant attention from other drivers on the road form far away.

Another objective of the present invention is to provide an illuminant triangular warning arrangement, which has an easy and convenient installation process that it can be assembled in matter of seconds. When the illuminant triangular warning arrangement is in used. its displaving area is large enough to attract other distance drivers attention.

When it is not in used. it can be folded into a compact package, so that it would not occupy unnecessary space in the trunk of the vehicle for easy storage.

According to the present invention, an illuminant triangular warning arrangement comprises a triangular clothe body and an illuminant device. The illuminant device comprises a battery box, a manual switch and a plurality of illuminating units provided on the triangular clothe body, in which each illuminating unit comprises a circuit board, a casing socket. a fitting washer, and a photodiode (LED). The present invention not only can provide the light reflecting function as in the conventional warning sigh, but also can provide flashing light, especially during low visibility condition in bad weather or nighttime, so that the driver and the troubled vehicle can be easily observed by the other drivers on the road.

Detailed Description of the Preferred Embodiment Referring to Figs. l to 7 of the drawing, an illuminant triangular warning arrangement according to a preferred embodiment of the present invention is illustrated.

The illuminant triangular warning arrangement comprises a triangular clothe body 20 and a plurality of illuminating units 30 installed on the triangular clothe body 20, wherein said triangular clothe body 20 comprises a triangular bottom clothe layer 21 and a triangular reflecting layer 22 which are made of a kind of polymeric material such as polyethylene (PVC).

A peripheral edge of said triangular reflecting layer 22 is sealedly connected to a peripheral edge of the bottom clothe layer 21 in a water tight manner, so as to define a hollow pocket 200 between said triangular reflecting layer 22 and said bottom clothe 21 (as shown in Fig. 4), The triangular reflecting layer 22 has a plurality of through holes 221 arranged evenly and spacedly thereon. The rear of triangular bottom clothe body 20 also has a suspension pocket 24 which located on the one of corner of said triangular bottom clothe layer 21, and the other of corner being attached on an elastic webbing 25 respectively of said rear of triangular clothe layer 21, wherein said suspension pocket 24 also has a bottom opening 241 to wearing on the top corner of reflecting plate 11 of triangular warning sign frame 10.

The suspension pocket 24 has a battery container 80 affixed thereon for receiving a battery box 90, wherein said battery container 80 has an opening 801 and a male loop and hoop fastener 802 positioned near said opening 801, moreover said suspension pocket 24 further provides a cover 81 near said opening 801 of said battery container 80, said cover 81 having an outer edge affixed on said suspension pocket 24 and a free end 811 of covering said opening 801 of said battery container 80, said free end 811 having a female loop and hoop fastener 812 provided at a location with respect to said male loop and hoop fastener 802 of said battery container 80 for fastening said cover 81 to said battery container 80.

The peripheral edge of the triangular bottom clothe layer 21, attaches a plurality of magnetic elements 26 and has a plurality of affixing holes 27, in which the magnetic elements 26 are adapted for attaching the triangular bottom clothe layer 21 of the triangular clothe body 20 to a metallic surface for spreading out the clothe body 20. A

plurality of suckers are firmly mounted on the affxing holed 27 respectively, for attaching the triangular bottom clothe layer 21 of the triangular clothe body 20 to a nonmetallic surface while spreading out the triangular clothe body 20.

Referring to Figs. 4,5A. and 5B, a plurality of illuminating units 30 which are installed on said triangular clothe body 20 and are electrically interconnected by electrical wires E, are positional within said hollow pocket 200 between said triangular reflecting layer 22 and said triangular bottom clothe layer 21 and installed respectively at said respective through holes 221 along said triangular reflecting layer 22, where in each of said illuminating unit comprises a transparent layer 31 having a peripheral edge affixed to a rim of said respective through hole 221 of the triangular reflecting layer 22, a circuit board 40 is positioned between the triangular bottom clothe layer 21 and the triangular reflecting layer 22. wherein two pairs of wire holes 41 are formed on two ends of said circuit board 40 is positioned between the triangular bottom clothe layer 21 and the triangular reflecting layer 22, wherein two pairs of wire holes 41 are formed on two ends of said circuit board 40 for said electrical wires E to respectively pass there through and to electrical weld to two electrical conducting regions 401 provided on two sides of said circuit board 40, said circuit board 40 further provided a plurality of welding holes 42 at a center portion for allowing a terminal end 71 of the photodiode 70 insert therein and weld on the electrical conducting regions 401 of said circuit board 40, and a plurality of affixing holes 43 surrounding the plurality of welding holes 42 for the clip end portion 521 of the affxing clips 52 of the casing socket 50 to engage therein.

A casing socket 50 is connected to the circuit board 40 by engaging the clip end portion 521 of said affldng clip 52 within said affixing holes 43 of said circuit board 40 through at least a fitting washer 60 and the through hole 221 of said triangular reflecting layer 22, therefore, the fitting washer 60 and the casing socket are pressed against said top surface of said triangular reflecting layer 22, a photodiode (LED) 70 being inserted into said center hole 51 of said casing socket 50, two terminal ends of said photodiode (LED) 70 being inserted into said welding hole 42 of said circuit board 40 and connected to said two conducting region 401 of said circuit board 40 respectively.
