Improve shadowless lamp lighting by adjusting photothermal ratio

In the past, the old shadowless lamp usually used more power, mainly because of its photothermal ratio. As the input power becomes larger, the instantaneous high heat causes the bulb absorbing a large amount of electric energy and generating heat. Therefore, improving the proportion of photothermal ratio, designing shadowless lamp that satisfies illumination and avoids excessive operating room temperature becomes a new topic for Mingtai company.

The photothermal ratio is the ratio of shadowless lamp luminous power and the wavelength of all electron spectra in the surgical illumination area. Shadowless lamp should have low photothermal ratio, it can effectively improve the visible light of the electromagnetic spectrum which will be used to illuminate the brightness of the surgical site. Therefore, the surgeon can perform surgery in a comfortable surgical environment, and the lesion tissue will not cause inflammation due to heat.

In contrast, the high photothermal ratio means that the energy emitted by the surgical lamp is used to highlight the surgical lighting area in the visible part of the electromagnetic spectrum. Therefore, the surgeon may feel hot during surgery, even if its illumination is sufficient.
