摘要: An LED night light having different power sources including a battery, outlet plug-in source, or interchangeable source incorporates geometric shape optics means(es) has more than one reflective which relative positions, distances, and/or orientations to create plurality of beams reflect retro-reflective by reflector means(s), so the beam(s) said LEDs will and pass though reflectors' project surface(s) surrounding ceiling, walls, floor all desire areas. At least means see-though permit passing through also beam within means's surface, device cost saving features is optional be selected provided.
