Intertek introduces a breakthrough technology for testing the performance of luminaries and other energy efficient lighting systems.
Over the last decade, there has been a steep increase in the demand of energy-efficient lighting products in India. This has led to the development of a number of voluntary and compulsory energy efficiency programs, performance initiatives and labeling standards. Compliance with any or all of these voluntary programs can be a significant source of differentiation, revenue, leadership and promotion. These labeling and energy efficiency programs have become a compelling reason for manufacturers to invest time and resources into the pursuit and achievement of these voluntary standards. To facilitate the same, Intertek have added the revolutionary Type-C High Speed Moving Mirror Goniophotometer and 3-meter Integrating Sphere testing system to its Luminaire Performance Testing laboratory in New Delhi, India.
What is a Goniophotometer?
A Goniphotometer is an advanced device used to measure the directional light distribution characteristics of luminaires. This device measures data in a series of spherical photometric coordinates surrounding the light source. Goniophotometer types are divided into three categories Type A, B and C. Intertek India has a Type C goniphotometer which has a Type C coordinate system. The elimination of tilting of the luminaire in Type-C goniophotometer makes it ideal for measuring the light output of position-sensitive Lamps. This type of goniophotometer creates the Type C web of data, the luminaire is normally aimed at nadir.
Capabilities of a Type C Goniophotometer
A goniophotometer is effective in measuring the following parameters and provide below graphical output/data:
What is an Integrating Sphere?
An Integrating sphere is a device that spatially integrates the radiant flux generated from a sample so that it can be detected with a single detector. The function of an integrating sphere is to spatially integrate radiant flux. The integrating sphere is equipment with a spectrometer (CCD detector), a baffle, an auxiliary lamp assembly, reflective coating, lamp mounting hardware, lampholder and associated electrical wiring.
Capabilities of 3-Meter Integrating Sphere.
Integrating Sphere is effective in measuring the following parameters:
