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 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.……
Like many other techniques in physics, ray tracing is another tough area and this technique is used in different production fields these days. For instance, it is used for production of views of a virtual three dimensional scene on a computer. It is also something connected with the propagation of light. Nowadays, software programs that enable reverse ray tracing are available in the market.
There are some software programs that not only takes care of reverse ray tracing, but LED reflector design can also be done easily with these programs. Lighting and illuminant manufacturing is an area that will never lose demand and with the advancement of technology, a number of different illuminants in attractive designs and fashions are now available in the market. The companies engaged in the manufacture of these illuminants can make the best use of the software program that will make their work easier.
Reflector-design.com acts as a perfect guide for design of parabolic mirror, one of the concept used for optical design systems.
