How to make the anti-glare for museum lighting

Museum lighting requires precise light distribution. However, each exhibit has a wide variety of exhibits, scenes, and graphic boards. So the lighting needs to be adjusted flexibly,and the light after the adjustment is also important for anti-glare. Before we start to tell about the anti-glare thing, let's take a brief introduction about what is anti-glare: [...]

What is CRI(Color Rendering) and how to show it?

In ancient times, people lived and worked depend on the sun for a long time, and they got light by fire at night. Under this condition, people have a relatively fixed understanding of the color of the observed object. That is to say, the color of an object is considered as its "real" color only when it [...]

What is indirect lighting?

     Indirect lighting is a kind of lighting effect that uses a luminaire or a light source to reflect the light source through walls, ceiling,mirrors, floors, etc. The key point is the light source is not directly projected to the object. Generally speaking, The below aspect of indirect lighting are very important. First is [...]
