What types and styles of surgical lights are there?

Let's talk about light source first: At present, shadowless lamps are mainly halogen lamps or LED shadowless lamps. In the early days, halogen lamps were used, but because of their short life (several hundred to 1 thousand hours compared with LEDs), the radiation (heat) was large. At present, there are many LED surgical lights on the market, which are characterized by long life (tens of thousands of hours) and low radiation (but some). Because there are many LEDs in each lamp holder, one or two will not have a great influence on the operation. Imported brands.

The structure of shadowless lamps is generally double or single. Double lamps, some two lamp caps are the same size, and some main and auxiliary lamps (auxiliary lamps) are one big and one small, mainly because the diameters of lamp discs are different. Generally speaking, the shadowless effect with large diameter is good. There are two types of lamp holders: porous type and integral reflection type. Due to the requirement of laminar flow in operating room, porous holes are rare now.

From the installation form, there are hanging type, wall hanging type and mobile vertical type (what I know is limited to Shandongmingtai).

The main parameters of shadowless lamp are illumination (whether it is bright enough), color temperature, color rendering index, spot diameter, light column depth, temperature rise due to illumination, shadowless degree and other technical indicators. Mechanically, there are rotation angles, the distance that the lamp holder moves up and down, and the balance of the lamp holder; If you consider saving energy, you should refer to the power consumption of the product. In fact, these indicators of officially registered products are mandatory in the manual (old products may not have such complete parameters, but generally give illumination, color temperature, power consumption and mechanical properties). You can ask the manual for reference.

Non-mobile shadowless lamp should consider the weight of the product, because it is related to the infrastructure, and the requirements for the bearing capacity of the foundation will also be given in the manual.

The above is for reference.
