Description

Surgical light with fine adjustment of light intensity

technical field

The present invention relates to the innovation of a surgical lamp with the function of fine-tuning light intensity, especially when the luminous efficiency of the light source is reduced below the original efficiency, the luminous intensity of the light source can be increased, thereby prolonging the overall service life of the surgical lamp. In addition to the accurate and consistent illuminance value of the lamp during the manufacturing process, decoration engineers or operating room physicians can adjust the optimal illuminance by themselves after the operation lamp is installed.

Background technique

It is known that a surgical light using a halogen bulb as a light source will generate a stable illuminance when a specific voltage or current is supplied. Therefore, in the mass production stage, the operating light has the lowest illuminance, the highest illuminance and the dimming of each segment between the lowest illuminance and the highest illuminance. The difference between the value and the design stage value is negligible.

In recent years, due to the obvious improvement of the luminous efficiency of LED, the use of LED as a surgical light source can not only prolong the service life of the light source, but also save energy. Therefore, more and more surgical lights choose to use LED as the light source. The minimum illuminance, the highest illuminance and the dimming values of each segment between the lowest illuminance and the highest illuminance are so large that the deviation between the design and mass production stages cannot be ignored, so that all products cannot be made accurate and stable during the manufacturing process. The illuminance value of , the reasons are summarized as follows:

1. The luminous efficiency of each LED chip supplied by LED manufacturers varies greatly.

2. The luminous efficiency of each LED chip will decrease significantly as the temperature rises.

Moreover, the luminous efficiency of LED will gradually attenuate with the increase of use time. Therefore, the use of LED as the light source of the surgical light also has a certain service life, and the LED industry's customary definition for the service life of LED is that the luminous efficiency of the LED decreases. To 70% or less of the original efficiency, this is because when the luminous efficiency of the LED is reduced to 70% or less of the original efficiency, the surgical light may not provide sufficient illumination in the surgical area, and according to the LED manufacturer's specifications , When the luminous efficiency of the LED is reduced to 70% or less of the original efficiency, although there is still a long service life, the remaining service life cannot be continuously and effectively used by the surgical lamp, thus forming a kind of illumination resource. waste.

In addition, since the pupils of human eyes will automatically shrink or expand to adapt to changes in the intensity of the light source, when the intensity of the light source changes too rapidly and rapidly, the eyeballs of human eyes may become hyperemic and prone to transient dizziness; according to this physiological In response, once the illuminance difference between the background lighting area of the operating room and the surgical lighting area exceeds 10 times, the eyes of the surgeon in the operating room will shift from the surgical lighting area to the background lighting area, so as mentioned above, the eyeball may quickly become congested and appear. Short-term dizziness, so no matter what kind of light source is used, it is known that the minimum illuminance, the maximum illuminance and the dimming levels between the minimum illuminance and the maximum illuminance cannot be adjusted after the surgical light leaves the factory, unless the control software is changed. Or replace parts, otherwise, when the illumination in the background lighting area of the operating room is low, the eyeballs of the operating room physicians' eyes may quickly become congested and the physiological problem of short-term dizziness is unavoidable.
