Description

LED shadowless lamp

technical field

The invention relates to semiconductor lighting technology, in particular to an LED shadowless lamp.

Background technique

Semiconductor lighting technology has been widely used in various fields because of its energy saving and long service life, and medical shadowless lighting is no exception. LED is a real cold light source. Under the same illuminance, its radiant energy is much lower than that of halogen tungsten bulbs. That is to say, when the surgical shadowless lamp using LED as the light source is used for surgical lighting, it will not damage human body tissue at all. As a new light source for surgical shadowless lamps, LED lights are an inevitable trend in the development of surgical shadowless lamps.

Shadowless lamps have high requirements on the uniformity of light in the irradiation area. In traditional LED shadowless lamps, the LED light source modules are generally arranged in a square matrix. Generally speaking, the large line of light in the irradiation area of this arrangement is uniform. Due to the distance between adjacent LED light source modules It is not equal. For the local target object being irradiated, the light in the direction is uneven. Although this difference is very small, for the medical shadowless lamp, it will also interfere with the surgeon's vision.
