Abstract
A lighting apparatus includes a reflector, a light source, and a lens unit. The reflector has an open side, and a reflective surface that extends from a periphery of the open side and that defines a compartment. The light source is disposed in the compartment and emits light toward the reflective surface. The reflective surface reflects the light from the light source towards the open side. The lens unit is disposed to close the open side and permits passage of the light reflected by the reflective surface therethrough. The lens unit includes a central lens portion, and first and second side lens portions respectively disposed on two sides of the central lens portion. The central lens portion and the first and second side lens portions are Fresnel lenses, and are configured to redirect the light passing therethrough to result in rectangularly-distributed illumination outwardly of the lighting apparatus.
