#operating light

Halogen operating lights have several disadvantages:

1. Heat Production: Halogen lights generate a significant amount of heat, which can be uncomfortable for both patients and medical staff, and may pose a fire risk if not properly managed.

2. Energy Inefficiency: They are less energy-efficient compared to Mingtai LED operating lights, consuming more electricity and resulting in higher operational costs over time.

3. Shorter Lifespan: Halogen bulbs typically have a shorter lifespan compared to LED or other modern lighting options, leading to more frequent replacements.

4. Color Temperature: Halogen lights may not provide as accurate color rendering as some LED lights, which can affect visibility and color differentiation in surgical settings.

5. Flickering: Some halogen lights can flicker, which may cause eye strain or discomfort for those working under them.

These factors make many facilities consider alternatives like LED lighting for surgical and operating rooms.

LED surgery shadowless light plays a very important role in medical industry. With the development of medical device, it design requirement also is improved. Then, under the current social development trend, what requirements should be met for the design of LED operating lights?

1. LED mobile operation lamp intensity should be suitable for the needs of the simple operating room

Some simple operating rooms have poor lighting requirements, when choosing operating light, you need to consider its illuminance firstly. Generally the single dome operation lamp illuminance can reach 150,000 Lux. If you have enough budget, another satellite light can be chosen as auxiliary light, maximize the elimination rate.

2. The power of LED operation lamp should meet the power supply standard of simple operating room

When surgical lamp factory sells surgical lamp to customers, the power should be noted. Too high or too low voltage can cause the surgical shadowless lamp to be unusable, resulting in the burning of the components inside.

3. Whether the LED surgery light can be moved in simple operating room

In some areas, especially in areas where natural disasters are more serious, the simple operating room itself is faced with a variety of risks, and there is a possibility of moving away at any time. Under such circumstances, the ordinary ceiling-mounted shadowless lamp is not as convenient to install and disassemble as the vertical portable surgical lamp. The hospital can choose the appropriate operating room shadowless lamp according to its own situation.

4. With camera function

With the development of medical digital imaging technology, the operating room can install hospital operating lights with camera function, wired or wireless camera, internal or external camera. Through the medical camera, you can diagnose and record the operation process when dealing with complicated surgery, or you can get expert help remotely.

In order to maintain good and stable operating room light environment, the operating room should be protected from direct sunlight, or colored glass can be used to facilitate artificial lighting.

Due to the high illumination requirements of the operating room, the installation position of the lamps is often limited by the number and location of the air outlets and other equipment. This is not only asked to meet the high illumination, but also the number of lamps should be limited to the appropriate range, and the energy consumption of the operating room air conditioner should be taken into consideration. The heat of the bulb should be as small as possible. It is recommended to use LED light source. Since the LED is cold light source, there is almost no temperature rise in the room, the patient has no uncomfortable feeling, and the risk of dehydration caused by the light source is avoided. In addition, it can also reduce the energy consumption of indoor air conditioners properly; the general light CRI of the operating room should be close to natural light, preferably between 4000 and 5000K, usually with a color rendering index of Ra≥90.

General lighting in the operating room should not use traditional magnetic ballasts, surgery shadowless light powered by conventional magnetic ballasts will be strobed due to AC power. Doctors perform surgery under this ever-changing stroboscopic light source. The visual system needs to constantly adjust the size of the eyeball pupil to ensure the stability of the retina illumination and imaging clarity. Long-term work will inevitably make the pupil sphincter fatigue due to excessive use. It will have an adverse effect on the surgery and will also cause some damage to the doctor's vision.

The AC electronic ballast is a new type of rectifier composed of rectification and filtering, high frequency oscillation and rectifier coil protection circuit. Since the power frequency is greatly increased to 55 kHz, even 80 kHz, 100 kHz super audio, the flicker frequency of the operating light is correspondingly increased to the area where the human eye is not sensitive, which alleviates the stroboscopic effect. At the same time, the buzzer interference is completely eliminated, the power consumption is greatly reduced, and the power factor of the operation lamp is improved. Electronic ballasts have great advantages at low voltages, but unfortunately, the ultra-high frequency also brings another adverse effect, that is, electromagnetic interference generated by high-frequency oscillations, that is, said that the higher the power frequency, the more serious the electromagnetic radiation phenomenon. With the development of modern medical technology, the precision electronic medical equipment used in the operating room is increasing. The electromagnetic interference influence of many electronic ballasts on the normal use of these devices cannot be ignored. For example, in cardiothoracic surgery, when the patient installs pacemaker, it may also be dangerous due to electromagnetic interference.

In summary, to solve these two problems, it is recommended to use LED light source mobile operation lamp, LED working mode is driven by external or built-in power supply, no ballast is needed, so the problem of strobo can be effectively solved, the good quality LED lamp can almost achieve no stroboscopic; In addition, the use of high-end isolated power supply can effectively reduce the electromagnetic interference of the lamp for precision instruments and prolong its life.
