More Information
Summary:A positioning device of light-guiding plate (2) is provided. Top limits are installed on two terminals of the lamp reflector of a surface light source device to let the light entrance plane be against the top limits when the light guiding plate is inserted into the reflector, so the light guiding plate of the surface light source device can be rapidly and accurately positioned without additional parts, meanwhile, the efficacy of protecting the light source to prevent from breaking is also achieved.
