Kuraray Co., Ltd. (headquarters: Chiyoda-ku, Tokyo; President: Fumio Ito) today announced the development of an energy-efficient and slim light guide panel for LED sign boards featuring an edge-light system (ELS). The product will be commercialized on May 15, 2009, through sign makers nationwide.
The new product is an ELS acrylic light guide panel for sign boards that use LEDs as the luminous source. Compared with the direct-illumination type fluorescent signboards now used extensively, this product is significantly thinner while offering even light emission over its entire surface. Moreover, as it cuts power consumption—an eco-friendly feature—it is also effective at reducing running costs. When the light source is attached to both sides of the board, the panel is effective for a length of up to 1,500mm. The product can be used in signboards as large as 1,500mm × 2,300 mm.
Kuraray offers two types of panel: A brighter 9mm type for large signboards or billboards and a thinner and lighter 6mm type for hanging signs and posters.
In addition to the original lineup, Kuraray will leverage its unique production system to respond to custom orders ranging from a one unit minimum to the maximum prescribed size without charging for the initial cost of making a customized mold.
The product comprises an acrylic light guide panel and reflection sheet. The light emitted from LEDs fixed at the sides of the panel travels in a controlled manner through the interior of the light guide panel and is evenly radiated through the diffusion sheet that constitutes the panel’s surface. The attachment of an advertising board to the face of the diffusion sheet transforms the panel into an LED sign board.
Reflecting the industry-wide trend toward eco-friendly products, the sign and billboard industry is also shifting from fluorescents to energy-efficient LEDs.
Responding to this trend, Kuraray leveraged its optical design and high-precision processing technologies cultivated in the development of optical-use screens and DVD stampers to achieve this light guide panel technology. With this new panel, Kuraray will contribute to the promotion of LED panels with low environmental burden.
