Abstract

A dental light comprises at least one light emitting diode light source configured to produce a light beam and at least one collimating lens system situated to receive the light beam. The collimating lens system is configured to collect and collimate the light beam. The collimating lens system can additionally modify the beam through controlled diffusion or shape the beam using an aperture.

Description

technical field [0001] This application relates to LED lights, and more particularly to LED lights used in dentistry. Background technique [0002] In the dental industry, dental lights - also known as dental operating lights or dental light fixtures - are used to illuminate a patient's mouth (oral cavity) during dental procedures. For example, dental lights aid in patient examination and diagnosis, tooth reduction and preparation, shade matching and restoration. [0003] Current dental lights mainly use incandescent lamps or quartz halogen lamps as light sources. These light sources are also often used with reflectors such as mirrors or other reflective surfaces. Light-emitting diode (LED) light sources offer several advantages over these sources, including long life, low power consumption, and greatly reduced radiant heat. [0004] However, there are some difficulties in applying LED light sources to dental lights. For example, in various dental applications, the quali...
