Light Reflector Design

In general, a point source is a sole identifiable localized source of something, which may be light, sound, heat, fluid or even pollution.Normally, these sources are known as point sources because they are generally calculated as the numerical point for making analysis easier. Here, the real source need not necessarily be small, if its dimension is negligible relative to other length scales.

 

 

 

Normally, a source of light is considered as a point light source if the imaging instrument’s resolution is too low to resolve its apparent size. When talking mathematically, an object will be regarded as a point light source if its angular size is much smaller as compared to the resolving power of the telescope, after considering the amount obtained by dividing wavelength of the light by the diameter of the telescope. Some of the examples for this are:

Illumination from a street light in a large-scale study of street illumination or light pollution.

Illumination passing through a pin hole that is viewed from a distance that is much higher than the size of the pinhole.

Illumination from a star located far away seen through a small telescope

 

 

 

 

The point light source calculation becomes important for some industries and these days, the calculation task has become easier with the availability of light reflector design software programs. Physics is an area that is considered tough and many calculations are to be done for each and every invention. But, nowadays, manufacturing companies can make effective use of software programs meant for different purposes like calculating light reflector design, LED reflector design, etc.……
