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.
