Lamp used for dental or surgical operations, is based on light-emitting diodes, reflectors, light blending unit and lens, with control of intensity and color temperature

摘要

The lamp includes light-emitting-diodes (LEDs) with a multi-LED light blending unit, followed by a lens. A mirror is included. A catadiotropic element (refracts and reflects) is used. A light-deflection mirror is included in the beam path between the blender and lens. LED intensity is individually or collectively variable. The lamp includes red, yellow, green and/or blue LEDs. At least one phosphor-converted LED (PC-LED) is included. Intensity is time-modulated and the color temperature is adjustable, preferably by a sensor.
