How it works: Laser cut panel have hundreds of tiny mirrors that powerfully redirect sunlight. A pyramid of four laser cut panels is installed inside the clear dome of a conventional pyramid skylight to produce an angular selective skylight. The result on sunlight is shown below:

A is a conventional skylight. It has a clear dome (green) in the roof and a diffuser panel (light blue) at the ceiling level. Low angle sunlight does not go through down to the ceiling diffuser and natural lighting is poor.

B is an angular selective Skyglazing skylight. Now, the laser cut panels onto the diffuser providing natural light to the room redirects much of the low angle sunlight.

C shows how a conventional skylight can disclose too much sunlight in the middle of the day in summer, which may overheat your room.

D shows how the room should be kept cooler in summer by the angular selective skylight rejects the high angle summer sun.
