Abstract: An LED (Light-Emitting Diode) lamp structure for reducing multiple shadows comprises a supporting element, LED light sources and a first reflector. The LED light sources are arranged on the supporting element and the first reflector is arranged in light paths of the LED light sources so that lights emitted from the LED light sources can be scattered or diffused (reflected) by the first reflector toward all directions. An object that is placed under the LED lamp structure can be illuminated by the lights while production of multiple shadows of the object can be reduced.

Abstract: Disclosed is a minimal incision surgical light source module with a light-emitting diode (LED), comprising a first LED, a first lens set, a reflector set, a second lens set and a fiber-optic connector. The first lens set, the reflector set, the second lens set and the fiber-optic connector are sequentially arranged along a light-emitting path of the first LED in a light-coupling configuration, so that light rays emitted from the first LED are coupled into an optical fiber by the fiber-optical connector. By implementing the minimal incision surgical light source module, the light rays emitted from the first LED are concentrated and condensed into a light beam after passing through the first lens set, the reflector set and the second lens set, thereby reducing a circumference of the concentrated light beam.

Abstract: A lighting apparatus having a separate control panel comprises a lamp holder and a light source module that is settled in the lamp holder.
