What is a shadowless lamp? The role of shadowless lights
What is a shadowless lamp? It is also a kind of lamp. Perhaps this kind of lamp is not common in our lives, but there is a place that people who work must often see it, that is, the operating room. Generally, this kind of shadowless lamp is referred to as the surgical shadowless lamp. What is the shadowless lamp? What is the role? Let’s take a look at Benwei light.
What is a shadowless lamp?
In fact, the shadowless lamp can't be "shadowless", it just dilutes the umbra, making it inconspicuous. Shadows are formed by light shining objects. The shadows are different everywhere on the earth. If you carefully observe the shadow under the electric light, you will find that the middle of the shadow is particularly dark, and the surroundings are slightly shallow. Surgical shadowless lamps are used to illuminate the surgical site to best observe small, low-contrast objects at different depths in the incision and body cavity. Since the head, hands and instruments of the operator may cause interference shadows on the surgical site, the surgical shadowless lamp should be designed to eliminate shadows as much as possible and minimize color distortion. In addition, the shadowless lamp must be able to work continuously for a long time without radiating excessive heat, because overheating will make the operator uncomfortable and dry the tissue in the surgical area.
The role of shadowless lights:
Brightness guarantee
The surgeon in the operating room must be able to accurately distinguish contours, colors, and movements. Therefore, as a surgeon, a light intensity close to the quality of daylight is required. The light of 100,000 lux is determined to be equivalent to the brightness of the sun at noon. In addition, in the surgical environment, most of the light is absorbed rather than reflected, which means that the surgical shadowless lamp must provide greater brightness.
The shadowless lamp can produce a maximum brightness of 150,000 lux, and the brightness can be steplessly adjusted. Only under this brightness, the surgeon can have 50% visible light in the operation area.
No heat production guarantee
Bright light will be accompanied by heat generation. If heat is generated during the operation, it will bring great harm to the surgeon and the patient. Therefore, what we need during surgery is lighting with only light and no heat.
Pathogen free guarantee
One of the basic elements of surgery is to keep the number of pathogens during the operation to a minimum. Therefore, we adopt the best surgical shadowless lamp shape design, with an appropriate placement position (behind the surgeon), which can effectively control the number of pathogens. .
Color temperature guarantee
Color perception is determined by the color temperature of the light. For example, the color temperature of daylight is 5600 kelvin; at the color temperature of 5600 kelvin, the light that human research perceives is white light. Therefore, experts recommend that the color temperature of the light in the operating room be at least 4000 kelvin; so it can produce the same light as daylight therapy. For human eyes, the color under the sun is clear, which makes the diagnosis more accurate and does not make the eyes fatigue of medical staff due to long hours of work.
Shadowless lamp
No shadow guarantee
Through the polygonal reflector, the shadowless lamp can meet the requirements of shadowless lighting. This reflection is involved by the computer, and it is formed by industrial stamping at one time, and the reflection rate is as high as 95%. His shape is very special: it is composed of many reflective surfaces that reflect light and illuminate the entire surgical area. As a result, many lights and shadows are superimposed to form an absolutely homogenous light beam. Surgery is performed in this light beam, that is, the light beam formed from 80cm below the lamp plate reaches the depth of the operation area.
Due to the perfect design of the reflecting surface and the large-size light reflecting surface, this same beam of light is not only as bright as daylight but also without shadows. And when the surgeon's shoulder, hand or head obscures part of the light source, it can still maintain very uniformity.
The above is the introduction of what the shadowless lamp is and what the role of the shadowless lamp is. I believe you will know more about it after reading it. The content is for your reference only, and I hope it can be helpful to you.
