Lighting laboratory

Our company has a unique lighting laboratory in Central Europe. With our GOV-1900 type goniophotometer manufactured by LMT and other measuring instruments, we can perform the following measurements.

Lighting measurements (goniofotometer):

•    Luminous flux
•    Luminous intensity
•    Illumination
•    Photometric distribution
•    Colour temperature

Electrical measurements:

•    Voltage [V], [Vpk]
•    Current [I], [Ipk]
•    Power [W][VAR][VA]
•    Frequency [Hz]
•    Power factor – PF
•    THDI
•    THDu
•    CFI

Temperature measurement:

•    10-channel temperature meter that allows the temperature of different components of luminaires to be measured simultaneously.

Luminance meter

Our lighting laboratory has an LMT L1009 type lluminance meter, with which the lighting control measurements of the already implemented investments can be performed.

Features:

• angular fields 3°, 1°, 20′, 6′ selectable
• display range 0.0001 cd/m2 (last digit) to 19 990 000 cd/m2
• measuring distance approx. 0.50 m to infinity
• photometer head with Si-photoelement, fine V(λ)-approximation
• 3½-digit display in viewing field and external, display hold switch
• ranging auto/manual, analog output, V.24-(RS 232-) Interface
• built-in rechargeable battery, automatic recharging circuit
• separate AC adapter 230 V, 50-60 Hz, handgrip, carrying case
• calibration, traceable to PTB standard, with LMT calibration certificate
• individual test report for V(λ)-approximation

Options:

• achromatic close up lens 1 for measuring distance approx. 0.09 m to 0.10 m
• achromatic close up lens 2 for measuring distance approx. 0.25 m to 0.50 m
• optical bench rod, 10 cm
• glare lens
• AC adapter in US-version for 115 V, 50-60 Hz
• BCD output instead of V.24-(RS 232-) Interface
• additional angular field 2′, resolution 1 cd/m2
• alternatively: additional angular field 2′ × 20′, resolution 0.1 cd/m2
• alternatively: additional angular field 3′ × 10′, resolution 0.1 cd/m2
• alternatively: special angular fields

IP laboratory

An IP testing laboratory has been set up at our headquarters, where we can currently measure and control the protection of luminaires against water (liquid) penetration.
