Pre-hospital emergency operation lighting equipment is used in the field of emergency use environment and power supply conditions, for operating room and patients operating wild lighting equipment or equipment. Mainly refers to the portable Field Operation lamp and the Flat War combination type Field Operation light.
The operating light is a tool used by physicians to observe the incision in the surgical site and the different depths of the body cavity. Now the operating lights are mostly used cold light source.
Cold light source is the use of chemical energy, electricity, biological energy to stimulate the source (such as fluorescent lights, neon lights, LED, etc.). The temperature produced by the light source is no higher than the ambient temperature, such as led by the use of electronic cavity to compound luminescence. But in the strict sense, led light-emitting is electroluminescent and heat generated, but relative to incandescent lamps and other heat source is lower.
Heat source is the use of heat to stimulate the light source, the incandescent lamp is typically converted from electrical energy to heat, and then heat energy into the process of energy. High heat loss and low luminous efficiency.
