Development and purchase costs are critical parameters when investing in the development of a lamp. The expected sales volume for the luminaire is the primary consideration.

Light distribution is the primary function of your lamp. It is easy to find standard optics that provide circular or linear beams in different angles and sizes. On the other hand if you need an asymmetrical beam or one that must meet a specific standard, finding a suitable standard lens becomes more difficult.

Efficiency mainly refers to the ratio of lumens emitted by the optics in the desired beam area compared to the full lumen output emitted by the LED. Standard lenses can lose 30% to 80% more lumens than custom lenses—even products that claim to be efficient. Hence the value in using a custom optical design.

What also makes research difficult is that each LED model has its own light emission. The “rayset”, which describes how each ray comes out of the source, is specific to each LED model—kind of like fingerprints. An optic may work very well for a certain LED model, but will not do so or will do so with losses for another LED model of equivalent size and power. This can therefore limit your choice of manufacturers and LED models and could prevent you from accessing better prices.

The method of assembling the optics is also important. A custom optic can limit the number of components by integrating a mechanical part of your lamp such as a joint, for example, or reduce assembly time with judiciously placed clips. This can translate into significant savings in the long run, depending on production volumes. When designing optics, we are able to simulate the influence of these additions on photometry and remove or reduce them if necessary.

Depending on the characteristics of your LED source lamp, custom-made optics can make a major or even essential contribution to the success of your luminaire in a competitive technological market. Furthermore, at a certain sales volume, a custom lens allows you to reduce the cost of your product compared to ones using standard optics.
