Power

Overview

...

Selux

Selux specifies the power consumption for all LED luminaires including all operating units as rated power.

Luminous flux

Overview

...

Selux

Selux specifies the luminous flux for all LED luminaires as rated luminous flux. This corresponds to the total luminous flux emitted by luminaires under normal operating conditions. The luminous flux for each Selux LED luminaire type is measured separately for each power level available. This data is recorded as absolute light intensity distribution.

Light yield

Overview

...

Selux

To calculate the performance (performance capability), light yield is specified as the ratio between rated luminous flux and rated power. For this the tolerance specified in the current standard is taken into account. Besides this, optimal light direction of Selux LED optics attains better lighting results and lower scatter light percentages than luminaires with similar system light yields.

Lifetime

Overview

...

Selux

A: Degradation
Degradation is loss of luminous flux over operating time. The lifetime of LEDs depends on the corresponding permissible degradation and is expressed as a percentage.
B: Abrupt Failure Value
Abrupt Failure Value (AFV) is the percentage of LED lights that fail completely within a predicated average rated lifetime (e. g. due to an electrical fault).

Loss of luminous flux

Overview

...

Selux

Selux circuit boards with selected LEDs work within an optimal temperature range due to coordinated thermal management, which keeps loss of luminous flux as low as possible over the LED’s operating time (degradation).

Maintenance factor

Overview

Selux

Loss of luminous flux over the operating time can be found in our datasheets in the lighting technology section. The individual maintenance factor can be calculated from this based on scheduled operating time.

Thermal management

Overview

...

Selux

With Selux Exterior core products, use of monitoring components (NTC Negative Temperature Coefficient) on circuit boards ensures the operating temperature never exceeds the permissible operating temperature at the measuring point (Tc). In exceptional cases where ambient temperature (Ta) increases excessively, the power is reduced by the NTC ensuring the LED does not suffer any damage or age prematurely.

Light colour

Overview

...

Selux

Selux LED luminaires are available in narrow shades of light colours. This ensures that the light colours of all luminaires with the same or a similar correlative colour temperature (CCT) are perceived as being identical. With Selux My White circuit boards, the customer can control the light colour. This can vary between warm white and daylight white.

Current supply

Overview

...

Selux

Besides the luminous flux, the efficiency of an LED luminaire essentially depends on the intensity of the operating current. As the current supply increases, the absolute luminous flux increases too. Both efficiency and lifetime will decrease however. At Selux, all LEDs are powered at a current level that is well below the permissible limit value for LEDs.

Light colour – lifetime

Overview

...

Selux

Selux quality standards require the use of premium quality LEDs and sustainable thermal management. This enables consistent light colours within very narrow tolerance ranges.

Colour reproduction

Overview

...

Selux

Quality of colour reproduction is expressed using the Color Rendering Index (CRI). Colour reproduction of LEDs is better than with conventional illuminants in most cases. Depending on the application, Selux can supply various levels of colour reproduction:

Examples:
Architectural spotlighting: > 80
Roadway lighting: > 70
Museum lighting: > 90

Replacement

Overview

...

Selux

With Selux LED module tracking the luminous flux of replacement modules can be adapted, ensuring the appearance and lighting technology characteristics of the overall system stay the same. For further information, see Selux warranty conditions for LED components on our website.

Dimmability / light control

Overview

...

Selux

All LED luminaires are suitable for control via DALI and in some cases via DMX too, enabling maximum system efficiency and creating versatile design options.

Visual comfort

Overview

...

Selux

Glare effect is restricted and regulated in individual products based on the relevant application areas (e. g. UGR < 19 for offices or TI for street lighting). Visual comfort is one of our declared objectives and, beside light quality and product quality, a distinguishing feature of all Selux luminaires.

Photobiological safety

Overview

...

Selux

When using Selux LED luminaires , photobiological hazards, in particular due to Blue Light Hazard, can be reliably precluded. Selux Exterior LED luminaires are equipped with optically efficient diffusers. These reduce radiation density in all directions, ensuring it remains below the permissible limit values at all times. Our luminaires can be classified under the unrestricted group 0 (no photobiological hazard) according to IEC 62471:2006.
