YGZF700/500 Overall reflective shadowless lamp
Through the multi-sided reflector, the shadowless lamp can safely meet the requirements of shadow-free illumination. This reflective surface is designed by a computer, industrially stamped and formed at one time, with a reflectivity of up to 95%. Its shape is very special: it is composed of many reflective surfaces that reflect and illuminate the entire surgical area. Accordingly, many lights and shadows overlap each other to form an absolutely homologous light column. The surgery is performed in this light column, that is, in the light column that starts from 80 centimeters below the lamp panel and reaches the surgical area.
Due to the perfect design of the reflective surface and the large-sized light reflective surface, this homogeneous light column is not only as bright as sunlight but also absolutely shadow-free. And when the surgeon's shoulders, hands, or head block part of the light source, it can still remain very even.
The multi-mirror reflection system, designed by optical experts, with more than 4500 lenses, truly makes the surgical field shadowless. The advanced color temperature compensation technology provides a color temperature closer to natural sunlight and evenly covers the entire surgical area.
The lamp cover glass is made of PC bulletproof glass, which has high-strength heat dissipation, wear resistance, and corrosion resistance.
The color temperature correction system designed by experts provides a color temperature of 4300K, which is close to natural sunlight, ensuring that the surgeon can clearly and accurately identify the colors of blood vessels, nerve bundles, and other tissues in the surgical area.
The power switch, brightness adjustment, and auxiliary lamp detection operations are integrated for practical use, with ten levels of brightness selection and brightness memory functions.
It has the characteristics of wide voltage operation and works stably within the range of AC160V - 250V of the mains power, with strong anti-interference ability.
The risk-eliminating automatic backup bulb switching system. One of the dangers during surgery is that the surgical bulb may fail. Through the automatic backup bulb switching system, the bulb will automatically switch and light up within 0.1 seconds, without any impact on the light intensity and the surgical area.
