LED with Continuous Spectrum from 400 nm to 750 nm
IMM Photonics presents a newly developed LED featuring a continuous spectrum from 400 nm to 750 nm.
Due to their internal design, standard white LEDs have a gap in the spectrum between 400 nm and 450 nm as well as around 500 nm. The new WISPEC-LED now sets out to close this gap.
Combined, the four chips that have been joined together on one compact LED deliver very homogenous white light. Depending on the application, the light can be individually adjusted because the chips can be controlled independently from one another. For example it ispossible to generate "Cool White" with a colour temperature of > 7.800 K. ACRI (Colour Rendering Index) value > 90 can be realized as easily as a lighting current of >130 lm. A colour mixing stick (optional) will allow for homogenous localized and spectral light distribution.
Due to pulse-width modulation (PWM),the LED is also dimmable by a ratio of 1:400 without changing its colour temperature.
The WISPEC-LED has been specially developed to replace halogen lamps, but is also used for applications such as microscope lighting or colour measurement. An additional advantage: Infrared radiation, which has detrimental effects on many applications is not an issue with the WISPEC-LED.
