Luminous intensity distribution, luminous flux efficiency, energy efficiency class, or color temperature (keyword dynamic white) are central aspects for the accurate use of LEDs. Also, the lamp market is extremely fast-paced, with an immense variety of products. In this environment, opsira accompanies its customers as a flexible and competent partner. This means:
From the product draft to serial production: opsira development support is there to assist you throughout the entire process – and also on the topic of redesigning with new LEDs.
Realistic optical simulation and optimization: opsira lightlab provides high-quality ray data and measures scattering properties (BSDF), transmission and reflection of the materials used.
Comprehensive portfolio: The opsira spectroradiometers, the goniophotometer robogonio, and opsira's integrating spheres provide standard-compliant measurement data.
Which industries are supported by opsira in the field of optical systems engineering?
opsira supports its customers in optical systems engineering primarily in the general lighting, automotive, medical technology and signal lighting sectors.
Furthermore, opsira takes care of all systems engineering issues of lighting, no matter in which industry. This includes, for example, luminous intensity distributions, luminous flux efficiency, energy efficiency class or color temperature, EULUMDAT, IES and much more.
What is luminous intensity distribution?
The luminous intensity distribution describes the emission of a light source or luminaire in all directions. The LID indicates the respective luminous intensity in candela (cd) or candela/lumen (cd/lm) for each direction.
What is luminous flux efficiency?
The luminous flux efficiency or the efficiency of a light source indicates the ratio between the electrical input (in watt) and the luminous flux emitted (in lumen). The unit of luminous flux efficiency is lumen per watt (lm/W).
Incandescent lamps commonly used in the past are in the range of 10 -18 lm/W. Modern LED systems are in the range of more than 200 lm/W.
What is EULUMDAT?
EULUMDAT is a data format (*.ldt) for the exchange of photometric data. The abbreviation EULUMDAT means "European Lumen Data Format" and has become the common industry standard in large parts of Europe. Nevertheless, the differentiation EULUMDAT is necessary because other countries and regions use other standards for photometric data (e.g. USA and Great Britain).
What does IES mean in optical measurement technology?
IES is an abbreviation for the Illuminating Engineering Society (see also www.ies.org/). IES also describes a file format that contains standardised photometric data. This data format was developed by the Illuminating Engineering Society and therefore has the abbreviation IES as its file extension (*.ies).
