Analysis of heat dissipation structure of surgical shadowless lamp


Shadowless lamp is a common medical device for medical workers, many people are very familiar with some parameters such as color temperature and illuminance, but the heat dissipation method of the surgical lamp may not be well understood. Today, Shandong Mingtai Medical Group will introduce you to the cooling system of surgical lamp LED.
With good convection heat dissipation, surgical lamp  can provide good heat dissipation for surgical shadowless lamps, to ensure the normal illumination and the long service life of the operation light. It comprises cover, mirror with an opening at the top end, insulating glass, handle and light source assembly; The light source assembly includes a light source and a heat shield body having an opening portion and a bottom vent hole; Forming a convection passage between the mirror disposed in the outer cover and the outer cover; A compartment space is formed between the reflector and the insulating glass which is between the reflector and the cover. A plurality of spacers are arranged between the insulating glass and the mirror, which can form a plurality of channels through the convection channel and the compartment space.
In order to prevent the entry of dust and affect the lighting effect or infection, etc., the sealing requirements of the operating light are generally very high. However, the heat dissipation of traditional surgical lights is usually open type. As disclosed in the 'lighting heat dissipation and fixture improvement structure', a through hole is arranged in the lamp chassis, and two ventilation plates are arranged in the fixing seat on the chassis, and a through hole for air circulation is arranged on the ventilation plate, and a fan is arranged below the through hole. Cooling effect by inputting external air through the fan. For closed type OR light, fix the metal tube with the bracket at the opening hole above the heat shield body, and place the metal tube directly above the bulb and extend down to the near bulb. The heat of the bulb is guided upward by the metal tube to dissipate heat from the top and the periphery of the cover.
Our company aims to produce halogen shadowless lamps that have good heat dissipation, maintain normal illumination and long service life of surgical lights.

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...
