LED P4 – Lens Coupling - Output Luminous Intensity Measurement
PL028 series
• NJC Technology
• High efficiency
• No vibration problems
• Free testing
Typical applications are
• Architectural lighting
• Lamps
• Street lights
• Most applications where a
compact light source is required
DESCRIPTION:
Verification of Luminous Intensity with coupling conditions between Khatod lenses and Z-POWER
®
P4 White LEDs.
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. PL02806,
PL02825 and PL02840.
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 the measurement of the LED brightness at 1 meter distance, without optic devices applied to the LED.
