Title: Surgical light
IPC: A61B90/30
Filed: 2020-05-07
Abstract: The present invention relates to a surgical light. According to the present invention, a diffusion unit formed by stacking a prism layer condensing light emitted from a light emitting unit and a diffuser layer evenly spreading and diffusing the light emitted from the light emitting unit is disposed on the lower part of the light emitting unit formed of a plurality of LEDs and a distance between the light emitting part and the diffusion unit is adjusted by using a support while the upper and lower surfaces of the diffusion unit are protected by a protective filter. When the light emitted from the light emitting unit formed of the plurality of LEDs is condensed by the diffusion unit and then evenly spread and diffused, shading or glare due to a difference in light quantity and color temperature of each of the plurality of LEDs does not occur, so that misdiagnosis and medical accidents caused by shadows or glare can be prevented during surgery or diagnosis, and eye fatigue can be reduced when used for a long time. In addition, since uniform light can be emitted to the diffuser, the installation number of LEDs forming the light emitting unit. In particular, since heat generated during operation of the LED of the light emitting unit is emitted to the outside through a heat dissipation unit in close contact with the ceiling part of the housing and a distance between the light emitting unit and the diffusion unit can be adjusted by the support, deformation of the surgical light due to the heat generated from the LED is prevented, thereby increasing durability.
