Abstract
The utility model discloses a light guide plate which comprises a holder, a light guide plate body, two LED light boards, a light-reflective paper, a brightness enhancement film, a PET (polyethylene glycol terephthalate) film and a protective film. The light guide plate body and the LED light boards are arranged in the holder, the two LED light boards are respectively disposed on two broadsides of the light guide plate body, the light-reflective paper is arranged on the downside and the other broadsides of the light guide plate body, and the brightness enhancement film, the PET film and the protective film are arranged sequentially on the top surface of the light guide plate body in a top-down manner. A thermal tape is arranged on the back of the LED light boards. The light guide plate is matched with a LED desk lamp with a prismatic light guide surface, so the heat dissipation is good and the light extraction is efficient.
Description
Technical field
The utility model relates to a kind of LGP.
Background technology
Because the LED desk lamp has different exiting surfaces, such as rhombus or semicircle exiting surface etc., and the main body of existing LGP is generally circle or square, can not be adaptive well from different LED desk lamps.Therefore, be necessary to design the suitable LGP of a kind of and the LED desk lamp with special shape exiting surface.
The utility model content
Technical problem to be solved in the utility model provides a kind of LGP, and this LGP can be suitable with the LED desk lamp with non-circular light guiding surface, and perfect heat-dissipating, and light extraction efficiency is high.
The technical solution of utility model is as follows:
A kind of LGP comprises mount pad, light conducting plate body, LED lamp plate, reflective sheeting, bright enhancement film, PET film and diaphragm; Light conducting plate body and LED lamp plate all are arranged in the mount pad; The LED lamp plate is 2, is separately positioned on two side edge of light conducting plate body, and reflective sheeting is arranged on bottom surface and all the other side edge of light conducting plate body; Bright enhancement film, PET film and diaphragm are successively set on the end face of light conducting plate body from bottom to up.
The back side of LED lamp plate is provided with the heat conduction adhesive tape.
Described light conducting plate body is prismatic light conducting plate body, rectangle light conducting plate body or semicircle light conducting plate body.
Beneficial effect:
LGP of the present utility model, light conducting plate body as main body adopts prismatic, semicircle or rectangle structure, therefore can be suitable from the LED desk lamp with different light guiding surfaces, and the employing of reflective sheeting, the luminous maximum possible that can ensure LED is sent from the LGP top, thereby light extraction efficiency is high, in addition, mount pad adopts metal material, thereby radiating effect is good.
