KCLP series REFLECTORS for Lambertian
KCLP Series
• High efficiency
• Available in 2 different beams
• Ø 17mm and Ø 20mm Standard
Typical applications are
• Portable lighting (flashlights,
bicycle, ... )
• Lamps
• Architectural lighting
• Most applications where a
compact light source is required
DESCRIPTION:
The KCLP series offers two reflectors designed for Lambertian LEDs.
These REFLECTORS have been studied by using software for optical simulation in order to get the narrow and medium beam
with a perfect homogeneous central spot.
REPORT:
From 1 m ± 0,02 distance, we have measured Luminous Intensity emitted by LED.
Such measurements have been repeated with the same test conditions but coupling LEDs to the lens Khatod cod. KCLP17CR,
KCLP17ST, KCLP20CR and KCLP20ST.
MEASURED DATA:
Column 1 shows p/n of the Lenses, column 2 shows Luminous Intensity detected measuring LEDs without lens, column 3 shows
Luminous Intensity detected on LEDs coupled with lens, column 4 shows the difference (X*) between col. 2 and col. 3

Test carried out after 5 min. of operation of the LED to 350 mA ~ , local power source GOSSEN KONSTANTER mod 3226-K118
Measurements carried out with Luxometer mod LUX-1337
of ISO-TEC and MINOLTA mod LS – 150
* X is the value of measurement of the LED brightness at 1 meter distance, without optic devices applied to the LED.
