FLATE TYPE LED ILLUMINATION APPARATUS

摘要

PURPOSE: A plate type led lighting device is provided to prevent the loss of incident light which is caused by light absorption and light scattering, thereby saving energy. CONSTITUTION: Light source units(10) are provided to be mutually faced on both of the left and the right side. An LED light source units comprises multiple LED light sources(11). A reflective sheet(20) comprises multiple reflective projections(21). The reflective projections are formed with Fresnel mirrors. The Fresnel mirrors reflect the projected light in parallel from the LED light sources in a fixed direction.
