Abstract

The invention discloses a multifunctional visual testing chart lamp. Reflection paper is attached to a base plate which is installed on the back of an inner frame. A hanging groove is formed in the top of the base plate and the inner frame. A three-section touch switch is installed at the bottom of the inner frame. A touch circuit board is connected with the three-section touch switch. The touch circuit board is provided with a V8 contact data cable. A wireless remote control switch is installed on the three-section touch switch in a linkage mode. A light guide plate is installed inside the inner frame. A patch LED is installed on the inner surface of the inner frame and located on the light inlet face of the light guide plate. The three-section touch switch at the bottom of the inner frame is connected with the patch LED through a wire to form a loop. A surface silk-screen diffusion plate is attached to the upper surface of the light guide plate, and a membrane printed with a logarithmic visual acuity chart is attached to the surface silk-screen diffusion plate. The membrane printed with the logarithmic visual acuity chart is pressed onto the inner frame through a transparent plate on the outermost layer. The multifunctional visual testing chart lamp is light and thin, convenient to use and capable of being used with a common mobile phone charging head and the V8 contact data cable. By matching the remote control switch, control is convenient, and one lamp can achieve multiple purposes.
