Technical Field
The utility model relates to a device for simulating natural light, in particular to a high-illumination lighting device for simulating natural light.
Background
One of the important applications of compact optical systems is in simulating natural light systems, where the optical module serves both as an imaging lens and as a light gathering effect. The main light sources in current analog natural light systems are Light Emitting Diodes (LEDs), Organic Light Emitting Diodes (OLEDs) or similar light sources. One of the most important issues to be solved when designing a natural light system is the brightness of the optical system, since the light source of a natural light system is often lower than a typical LED to take into account the full spectrum. This problem is most important for non-optic nerve path related applications because it is desirable that the intensity of simulated natural light in a room be comparable to the intensity of real sun illumination into a room.
The pursuit for high brightness is a complex optical solution and many practical applications are still not bright enough. On the other hand, there is a high demand for mirrors in terms of manufacturing procedures and operation.
