How To Choose LED Surgical Lights

For many years, choosing surgical lights has been a challenging process for surgeons and hospitals. Since the introduction of expensive LED operating room lamps in the OR as an emerging lighting technology, the challenge of choosing surgical lights has increased.

Some studies have pointed out that dental surgical lights is the source of lami-nar airflow disturbances. The increase in the size and thermal load of the OR lamp is associated with more adverse effects of laminar airflow than the smaller size and thermal load. Although there is still no clinical evidence, these effects may ensure the sterility of the wound by bringing more contaminated airborne particles to the surgical site. Therefore, hospitals tend to choose a small auxiliary lighting system instead of a large main light to minimize airflow deformation and save money.

To assist hospitals in the OR lamp purchase process, some authors have described surgeons’ requirements for surgical lighting. 2-10 have reported several important aspects of surgical lighting – such as light volume, shadow reduction, beam directivity, heat production and Light color.

It is important in all cases to obtain the proper amount of light and the correct color of light at the surgical site (such as the wall mounted dental lamp), as these aspects have been shown to affect the performance of visual tasks.

The reported surgeon lighting requirements have been converted to objective guidance and measures and have been developed as standards for surgical lighting. This standard describes the range of different light color characteristics and the range of light quantities that the OR light should conform to.

In addition, it describes a test scenario for measuring the maximum amount of light. These scenarios are based on clinical conditions, such as the surgeon’s head blocking the beam or light from penetrating the deep cavity. Although the surgical OR lamp meets the above criteria, there are still complaints about light quality and ergonomics.
