Ot-Dtr78/Dt61 LED Shadowless Operating Lamp

Product Description

OT-DTR78/DT61 LED Shadowless Operating Lamp 

Features:
An imported LED cold light source is adopted as operation lighting. As a genuine cold light source, there is almost no temperature rise at the doctor's head or the wound.
The white LED has a feature of color temperature which is different from the light source of common shadowless lamps for operation. It may enhance the chromatic aberration between blood, other body tissues and organs, and it thus helps the operating doctor to have a clearer view.
Digital means are adopted for stepless regulation of LED brightness. The operator may adjust the brightness based on his/her own brightness adaptability.
The color temperature can be adjusted as preferred or according to the type of surgery.
The LED shadowless lamp is pure-DC power supplied, without any strobe or harmonic interference with other equipment in the working area.
The imported switch power supply is adopted to control the voltage, making the work voltage permanently stable.
The removable handle sheath can be disinfected at the high temperature of 135.
A special optical system is adopted so that the light is evenly illuminated on the observed objects in 360∑ , without any virtual image and with high definition.
The service life of LED shadowless lamp is long (50, 000h), far longer than that of traditional tungsten halogen lamp (1, 500h), and it is over twenty times of the service life of energy saving lamp.
LED has high luminous efficiency and it is impact-resistant and strong to resist crumbling, without  contamination. The light it sends contains no infra-red or ultraviolet radiation pollution.
The no welding titanium alloy arm and the streamline-designed lamp cap better meet the design requirements of modern clean laminar flow operation rooms. Its fashionable appearance provides a new attraction for hospital operation rooms.
