Description
Technical field
The utility model technology relates to a kind of many minute surfaces shadowless lamp reflector.
Background technology
Operation shadowless lamp is one of hospital operating room visual plant, and performance quality such as its illumination that provides, no shadow degree and the illumination degree of depth will concern operation quality and patient health.And as the reflector of one of operation shadowless lamp part, decisive role in guaranteeing above-mentioned three big performance qualities then.At present, for satisfying the needs that purify operating room, the shadowless lamp lamp holder mostly adopts the configuration design of aerodynamic, thereby produced " whole many minute surfaces shadowless lamp reflector " this new technology, and utilize the CAD method that reflecting surface is carried out the optical system design, that is: shape such as bowl-shape reflector inner surface are divided into several layers, every layer is divided into some equal portions again, forms some (every layer of isodisperse sum) individual facet mirror.On the ad-hoc location time, light source and each facet mirror have all formed an independently sub-optical system in spot light places reflector.In this sub-optical system, level crossing reflexes to working region (operating table of shadowless lamp below) with light, forms trapezoidal (near a square) hot spot.And thousands of such hot spots are around, stack, combination, the approaching light beam of illumination in just good, the spot diameter in high illumination of working region formation, no shadow degree effect, thus satisfy the need of medical operating and other industries.
According to test to some actual products on the existing market, find to exist mostly in hot spot obscurity boundary, the light beam defectives such as illumination change is bigger, therefore, press for a kind of high-quality shadowless lamp reflector.
The utility model content
The purpose of this utility model is to provide a kind of high-quality many minute surfaces shadowless lamp reflector.
For reaching above-mentioned purpose and other purpose, many minute surfaces shadowless lamp reflector of the present utility model is characterized in that: be round cap shape, diameter and crown diameter are than between 3.64871-3.64872 at the bottom of the cap; Diameter and cap height ratio are between 2.641-2.6411 at the bottom of the cap; Be divided into 15 layers by the reflecting surface to crown at the bottom of the cap, every layer is divided into again successively: 68,69,71,71,72,71,71,69,67,65,62,59,55,51,46 facet mirrors.
Preferably, diameter is 580 at the bottom of the described cap, and the crown diameter is 158.96, and the cap height is 219.51.
In sum, many minute surfaces shadowless lamp reflector of the present utility model is that the design optimization through " MFER_CAD S " system designs, and therefore, illumination change is bigger in its hot spot obscurity boundary, the light beam etc., and defective all makes moderate progress.
