Surgical lamp with light intensity fine adjustment function

The invention relates to an innovation of a surgical lamp with a light intensity fine adjustment function, in particular to increase the luminous intensity of the light source when the luminous efficiency of the light source is reduced below the original efficiency, thereby prolonging the overall service life of the surgical lamp, so that in addition to the surgery The lamp has an accurate and consistent illumination value during the manufacturing process, and allows the decorating engineer or the operating room physician to adjust the optimal illumination to the illuminator after the surgical lamp is installed.

According to the conventional surgical lamp using a halogen bulb as a light source, a stable illumination is generated when a specific voltage or current is supplied. Therefore, the minimum illumination, the maximum illumination, and the interval between the minimum illumination and the maximum illumination of the surgical lamp during the mass production phase The difference between the illuminance value and the design phase value is negligible.

However, in recent years, due to the significant improvement in the luminous efficiency of LEDs, the use of LEDs as a surgical light source not only extends the life of the light source, but also saves energy. Therefore, more and more surgical lamps choose to use LEDs as light sources, and these use LEDs as light sources. The minimum illumination, the highest illumination, and the illuminance values between the minimum illumination and the maximum illumination are too large to be negligible in the design and mass production stages, so that all products are not accurate during the manufacturing process. The reason for the stable illuminance value is summarized as follows:

1. There is a large difference in luminous efficiency between LED chips supplied by LED manufacturers.

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

Moreover, the luminous efficiency of the LED will gradually decrease with the increase of the use time. Therefore, the LED as the light source of the surgical lamp has a certain service life, and the LED industry has a customary definition of the LED service life as the LED luminous efficiency is lowered. Up to 70% or less of the original efficiency, 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 field, and according to the specification of the LED manufacturer 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 utilized by the surgical lamp, thereby forming a waste of illumination resources. .

In addition, since the pupil of the human eye is automatically reduced or enlarged to adapt to changes in the intensity of the light source, when the intensity of the light source changes excessively and rapidly, the eyeball of the human eye may be congested and prone to transient dizziness; Once the illumination difference between the background illumination area of the operating room and the surgical illumination area exceeds 10 times, the vision of the operator's eye will be transferred from the surgical illumination area to the background illumination area, so as mentioned above, the eyeball may be rapidly congested and short-lived. It is dizzy, so no matter what kind of light source is used, the minimum illumination, the highest illumination and the illumination between the minimum illumination and the maximum illumination cannot be adjusted after the surgical lamp is delivered, unless the control software is changed. Replace parts, otherwise the operating room will be low when the illumination in the background lighting area of the operating room is low The physiological problem that the eyeball of the doctor's eye may be rapidly congested and has a short dizziness is unavoidable.

The main object of the present invention is to increase the luminous intensity of the light source when the luminous efficiency of the light source is reduced below the original efficiency, thereby prolonging the overall service life of the surgical lamp, so that the surgical lamp has an accurate and consistent illumination during the manufacturing process.

When installed in the operating room, the illumination range of 100 cm outward from the middle of the lamp head 2 of the surgical lamp should be between the highest 160,000 Lux and the lowest 40,000 Lux, although the drive circuit 4 has a relative 160,000 Lux. With the driving value of 40,000 Lux, but the quality of the light source 3 and the illuminometer error will affect the reading of the final illuminance, so to solve this problem, each light source 3 can enter the highest and lowest limit fine-tuning mode of brightness, thereby resetting And the memory drives the value of 160,000 Lux and 40,000 Lux.
