Design and features of the Spotlight LED
The Spotlight LED is based on a construction technology with parabolic reflectors. The LED chip is located in the focal point of a metallic micro reflector, which is extended in its parabolic geometric shape by a plastic reflector inserted into the metal reflector.
Optical beam shaping is achieved by combining both reflectors: the metal reflectors captures the light rays emitted at large angles to the optical axis and guarantees the module’s high optical efficiency, while the plastic reflector also redirects the light rays emitted at small angles to the optical axis by total reflection thus ensuring the the module’s very narrow beam opening angle.
Important for some applications is the property of the spotlight LED to emit only”cold” light without infrared components. This enables their use in conjunction with temperature – sensitive materials, on temperature . sensitive electronic sensors and also on foodstuffs,e. g. chocolate pralines.

Power LED Spotlight
The Power LED Spotlight can be manufacted either with a microstructured submount or as an LED in SMD design. Characteristic for both is the aluminum cylinder for heat dissipation of the LED power loss. The LED module can therefore be plugged in purely electrically without having to take into account the otherwise necessary thermal heat dissipation via the plug contact.
