Title:
LIGHT EMISSION AND REFLECTION COMBINED SIGN PLATE
Document Type and Number:
WIPO Patent Application WO/2016/178467
Kind Code:
A1
Abstract:
The present invention relates to a light emission and reflection combined sign plate, and more particularly, to a light emission and reflection combined sign plate enabling light to pass through only an edge portion of a black number and a red circle and to be blocked or not to be irradiated in the remaining portion, so that the sign plate is exactly distinguished even at a long distance. The features of the present invention is characterized by comprising: a sign plate main body (10) including a diffusion plate (11) for light diffusion, an outer plate (12) protruding a predetermined height along the circumference of a rear surface edge of the diffusion plate (11), an intermediate partitioning plate (13) protruding at a position spaced a predetermined distance inward from the outer plate (12), and an inner partitioning plate (14) protruding spaced inward from the intermediate partitioning plate (13); a retro-reflective sheet (20) including a red reflective sheet (21) having a circular band shape and attached to a front surface edge of the diffusion plate (11) so as to cover a portion between the outer plate (12) and the intermediate partitioning plate (13), which are installed on the rear surface of the diffusion plate (11), a white reflective sheet (22) attached to cover the inner space of the red reflective sheet (21), and a black reflective sheet (23) attached to a central portion of the white reflective sheet (22) to guide a traffic sign; a first LED module (30) installed along the circumference of the outer surface of the intermediate partitioning plate (13) to irradiate light to a space between the outer plate (12) and the intermediate partitioning plate (13); a second LED module (35) installed along the circumference of the inner surface of the inner partitioning plate (14) to irradiate light to the inner space of the inner partitioning plate (14); a traffic sign guide unit (40) provided on the inside of the inner partitioning plate (14) to prevent the light of the second LED module (35) from being transmitted, and installed at a corresponding portion of the rear surface of the diffusion plate (11) corresponding to the attached portion of the black reflective sheet (23) and at a portion spaced a predetermined distance from the edge of the corresponding portion to thereby guide the light to be transmitted along only the edge of the black reflective sheet (23); a cover plate (50) coupled to the outer plate (12) to close an inner portion of the display plate main body (10); a power supply means(60) supplying power to the first LED module (30) and the second LED module (35).
