A LED ceiling light is disclosed. It comprises a housing (10) covered by a lens (20). The lens has a planar section holding optical structures, parallel to a planar reflector (30) within the housing. A plurality of LEDs (50) is mounted within the housing recessed against the reflector. Light emitted by the LEDs is at least partially reflected by the lens towards the reflector and reflected back to a different section of the lens, passing the lens to the outside. Therefore, the light output ratio will be increased. There are further side reflectors for limiting radiation to the sides of the lamp. |
