Description

Dental lamp with light emitting diode

This creation is about a lamp, especially a dental lamp with a light emitting diode.

In the dental industry, dental lights are often referred to as dental surgery lights or dental surgery lamps, and are used to irradiate a patient's mouth (oral cavity) for necessary treatment during dental treatment. For example, dental lights help check and diagnose the patient's oral condition or dental restoration.

Current dental lamps use an incandescent lamp or a quartz halogen lamp as the light source, which is usually used together with a reflective element (such as a mirror or other reflective surface). Light emitting diode (LED) light sources are superior to these light sources, including long life, low power consumption, and greatly reduced radiant heat. Dental lights are mainly divided into reflective and projection types. Reflective dental lights use LED light sources to hit the reflector group, and then collimate the light onto the focal plane required by the dental luminaire to produce a uniform light spot.
