LED shadowless lamp common fault solution


LED shadowless lamp is a medical lighting tool used by medical personnel to observe the incision of the surgical field and different depths of tissue in the body cavity. Shadowless lights often have a variety of sudden failures during use. Mingtai Company summarized the common faults of LED operating light for everyone.
1. The main light is off and the auxiliary light is on. ZF series operation light has automatic switching function in the circuit control. When the main lamp is damaged, the auxiliary lamp will light up to ensure normal operation. After surgery, the main lamp bulb should be replaced immediately.
2. Light is not on. Open the top cover, check the transformer and power supply voltage to see whether thay are normal, if both are no problem, please find a professional to repair.
3. Transformer damage. There are generally two reasons for transformer damage: Supply voltage and excessive current caused by short circuit. The latter should ask a professional to repair.
4. The bulb is often damaged. Check whether the bulb is configured according to the rated power specified in the instruction manual and whether the power supply voltage is normal.
5. Disinfection handle deformation. Surgery light handle can be autoclaved, but the handle can not press heavy objects during disinfection, otherwise it will cause the handle deformation.
6. Move operating light angle, the light is off. This is mainly because the sensors at both ends of the arm will cause poor contact after a period of use. In this case, the professional should be asked to maintain it once.
7. Lamp head drift. After using for a period of time, due to the heavy weight of the operating lamp head, a large friction force is required for positioning, lamp head drift is generated, the upper positioning screw can be tightened to solve the problem.
8. Surgery shadowless light dims. Reflective glass for cold light shadowless lamps using coating technology. Generally domestic coating technology has only two years of life, after two years, the coating layer will cause problems, the reflection will become dark and foaming. In this case, you need to change the reflective bowl.

Surgical teaching system solution

图片
Why do we recommend the surgical teaching system solution? The first reason is the driving force for the development of the medical imaging system market. National policy support: The state encourages the development of digital operating rooms and has launched research on related topics. The development of medical information needs; with the advancement of medical industry information construction, the demand for video teaching, telemedicine, and information archiving has increased. Product performance improvement: The development of high-definition camera, network transmission and other technologies has accelerated the application of camera products in the medical industry. Medical accidents occur frequently and doctor-patient disputes increase. The frequent occurrence of medical malpractice prompted the hospital to archive video in order to avoid disputes. The second reason is that the surgical teaching system is the key to the advancement of the hospital. Conduct li...

Inspect before using the medical pendant

图片
Medical pendant is an indispensable gas supply medical equipment for modern operating room. Its main function is to supply oxygen, absorption, compression and other medical gases in the operating room. It is recognized by healthcare professionals because of its superior performance. However, we should do the inspection before using it, so that we can be prepared. Pre-inspection work of medical pendant: 1.        Check if all the parts of the PICU pendant are intact. Sometimes, when transporting or storing, due to the accumulation of products, the structure will be deformed. Be sure to check before installation, do not ignore the problem of deformation and damage, otherwise it will easily collapse or break due to improper force when used. 2.        Check that each bracket is complete and ensure that no items are missing, including instrument platform, drawers, infusion stand, sundries, etc. Although the lack of these pa...

What is the difference between cold light source and thermal light source?

图片
  The cold light source we often say does not actually refer to those light sources that do not generate heat during the light-emitting process, but refers to the light-emitting method that is not like the traditional light source that converts heat energy into light energy. In fact, it refers to a cold light source that uses chemical energy and electrical energy to excite the light source, and has the characteristics of variable flicker. The thermal light source we are talking about is a light source excited by thermal energy. During the light-emitting process, most of its energy needs to be converted into thermal energy, and then converted from thermal energy into light energy. Therefore, the thermal energy loss is relatively high, and the luminous efficiency is not cold light source. high. However, there are also advantages. Hot light sources can be directly connected to the circuit, and the maximum brightness can be achieved at the moment of power-on, but cold light sources can...
