Spot Light Coolers
For spot light LED coolers we typically aim at developing very compact coolers which allow our customers to use the most powerful COB, LOB or discrete LED engines on these.We understand that the smaller the light source can be, the easier narrow beam angles of high quality can be produced.As a direct result we concentrate ourselves on developing LED coolers with a high degree of conductive capability, so that the heat from the small source can be absorbed as fast as possible into the LED cooler.For tilted spot lights we design a structure as open as possible so free air convection under these tilted angles can still occur without drastically reducing the thermal performance of the LED cooler.A good example of perfect spot light coolers is the second generation pin fin LED coolers we brought to the market - these coolers can be used under a full 90° beam orientation without any thermal impact.

Our standard spot light LED coolers show a variety of mounting holes, enabling you with a wide choice of LED engines as well as connectors and optics. We foresee Zhaga book 3 as a standard on all our spot light LED coolers (mounting pitch 35mm, overall circle diameter 50mm) - the Zhaga book 3 standard is probably the most implemented standard, with availability of a wide range of compatible led engines as well as led connectors from BJB, Bender+Wirth, TE connectivity, Molex, Ideal Industries,... All together you get an incredible wide score of led engines ranging from 1000lm all the way up to 7000lm combined with lenses and reflectors all the way down to 3 degrees.
Another interesting standard for spotlights which is rather new and not yet fully known under lighting designers, is the Zhaga book 11 standard. While the power density of COB and LOB LED engines has been drastically increased, the sizes have been reduced in the same rate, so there was also a need for a new, more compact Zhaga standard. With mounting pitches at 25mm and an overall size of 35mm, this Zhaga book 11 standard plays perfect on this market tendency. In contrast with Zhaga book 3 there are only a few connector makers offering the Zhaga book 11 standard in their package, as there are BJB and Bender + Wirth.
Don't forget your thermal interface material! By choosing the right interface material, you not only reduce the overall temperature of your LED junctions and increase as a result the life time, it also is a guarantee for consistency in the manufacturing. On the other hand the application of thermal interface material can become rather expensive and a time and labor intensive. Therefore we advise you to use our pre-assembly services on thermal interface materials - see "LED thermal interface materials" The higher the power of your application, the more crucial this knowledge on thermal interfacing will become. When you still would like to apply your thermal interface locally at your place, but need further advise, don't hesitate to contact our engineering team at email@example.com
