The gyroscope 5 transmits the tilt angle of the head of the medical staff to the control panel 3, and when the gyroscope 5 measures the tilt angle of the head of the medical staff at a certain angle interval (for example, 15° to 25° or In any other suitable angle interval, that is, when the head of the medical staff is in a certain position, at this time, the control software in the control panel 3 sends a command signal to control the LED group 2 to be turned off, so as to avoid a certain head of the medical staff. When an operation (such as surgery) lags behind and suddenly raises another job (for example, changing an appliance, performing another treatment, or performing other non-treatment operations), the LED light group 2 on the head emits The light will directly hit the eyes of others, causing discomfort or injury to the eyes of others.

The above description is only a preferred embodiment of the present application, and the present application is not limited to the above embodiments, and there may be local minor structural changes during the implementation, and various changes or modifications to the present application do not depart from the spirit of the present application. The scope and spirit of the invention are intended to be embraced by the appended claims.

Industrial applicability

The smart headlight provided by the embodiment of the present invention improves the speed and accuracy of the operation, reduces the workload of the medical care, improves the comfort of the doctor's operation, and reduces the probability of causing discomfort or injury to the eyes of others.
