The correct choice of beam angle is also very important for lighting design, for some small ornaments, you use a large angle you irradiate it, light scattered evenly, no focus, the desk is relatively large, you use a small angle of light to hit, there is a concentration of fresh fruit, but not evenly, there are dim places. Not good for reading and working. There is also the position of the lamp is also extremely delicate, let us learn more about it.
A. What does the beam angle look like?
The light emitted by the lamp is distributed in space in a three-dimensional form. Figure 1 shows the light distribution curves used in the professional field and commonly used in the workplace. Figuratively speaking, imagine the lamp as a bathroom shower. When sprinkling water downwards, the curtain of water forms a certain shape in space, and the extent to which the droplets fall to the floor can be understood as the extent to which the lamp illuminates the floor. Some of the water droplets are sprayed onto the walls before they hit the ground, leaving a profile on the wall that is the arc of light when the spotlight washes the wall.
B. What does the Angle of the beam have to do with me?
The usual use of spotlights in the home improvement sector is to wash the walls to illuminate a hill-shaped arc of light, with different beam angles leaving different arcs of light on the wall. But what determines the different sizes and positions of these arcs of light?
a) Angle: For example, if the shower is spraying water droplets at a large angle, the water curtain formed in the space will be wider, and the range left on the wall will be larger. (The greater the beam angle of the spotlight, the greater the angle of the light arc left on the wall).
b) Distance from the wall. The distance from the wall determines the shape of the light arc, provided the beam angle is constant.(The closer the spotlight is to the wall, the higher the arc of light) (The farther the spotlight is from the wall, the greater the range (size) of the light arc and the weaker the intensity will be).
