By: Harendra Vishwakarma

2.  3D Modeling Tool – Unigraphic, NX,
Solid Edge, Rhinoceros –Part Drawing and
assembly drawing.
 2D Modeling Tool – AutoCAD, CAM,
 Design Evaluation Package –
Softwares, Simulation tools
 PCB Design Tool – Protal,
 Dialux – Lighting Designing &
Simulation tool,

3.  Optical instruments:
 Integrating Sphere – Lumen measurement of
luminaire, Chromaticity, Color Rendering Index,
Dominant Wavelength, FWHM,
 Lux meter – Lux value measurement at specific
distance, Ft-Cd measurements.
 Luminance Meter –Luminance
measurements at surface (Cd/ m2)
 Spectroradiometer – Exact Color and
spectrum (W/ m2 –sr-nm)
 Goniophotometer/Goniospectrometer
- Generating IES files for luminaire, polar curves,

4.  Thermal Measurements:
 Thermocouples, (Contact mode method) –
Temperature profile of LED module and Luminaire with
respect to room temperature, Thermocouple needs to
be <+/-1.1C or +/-0.4% accuracy for Case Temperature
during test
 Infra-red pyrometers, (Non-contact mode
method)– Junction temperature measurement, heat
sink temperature.
 Digital Temperature Meter - Temperature
profile of LED Luminaire

5.  Electrical Measurement
Equipment:
 Power Supply analyzer - Electrical
parameters such as Total power, Power Factor, Total
Harmonic Distortion,
 AC regulated power supply
 DC regulated power supply (Constant
Current)
 Megger – insulation testing,
 Leakage current meter –
 Earth Resistant Test (ECR)-
 V,A,W Test Meter -

6.  Environment testing:
 Dustproof Chamber,
 Humidity chamber –
 Resistant to Heat (oven) –
 IP Testing –

7.  For indoor – min 15’x10’ room with height
of12’ and arrangement for mounting luminaire
horizontally and vertically at various heights,
 This room will have all dark walls with reflection
les than 10%.
 This placed will be used to check lux values of
luminaire/lamp,
