A light emitting structure around a keyboard backlight module is disclosed to include a light guiding plate comprising a light source, a flat-shape reflecting layer disposed on one side of the light guiding plate, and a transparent film of a light blocking layer disposed on other side of the light guiding plate and comprising a light absorbing layer. A deflection portion is bending inwardly toward the reflecting layer and then extending outwardly to form a flat-shape positioning portion adhered to the reflection layer by an adhesive layer. The light source can project light toward the light guiding plate and pass part of the light from the light guiding plate to the deflection portion due to diaphaneity of the material of the transparent film. A light emitting area can be formed around the backlight module, lightening the connection port of the electronic device or other area needed to be lightened.
A light emitting structure around a keyboard backlight module, comprising a backlight module which is provided with a light guiding plate, a predetermined light source disposed at least one side of said light guiding plate to project light toward said light guiding plate to enable said light guiding plate lighting, and a reflecting layer having flat shape and disposed at a side surface of said light guiding plate, and a light blocking layer having at least one transparent film and disposed at other side surface of said light guiding plate opposite to said reflecting layer, a light absorbing layer formed on outer side surface of said transparent film, and a deflection portion formed by bending said transparent film at peripheral of said light absorbing layer and adjacent to said light guiding plate toward said reflecting layer, and said deflection portion bent inwardly to enable said light emitting from lateral portion of said light guiding plate to pass through to form a light emitting area at peripheral of said backlight module, a positioning portion having flat shape formed by extending said transparent film outwardly to adjacent to said reflecting layer, an adhesive layer formed between said positioning portion and said light blocking layer for binding said positioning portion and said reflecting layer.
