Regiolux luminaires may only be equipped with light sources specified on the identification plate and in the approval certificates. Use of other lamps as well as LED and T5 adapters does not constitute proper use according to intentions
and may lead to functional impairment and danger. As a part of our legal product monitoring obligation in accordance with Paragraph 6 Section 4 of the German Product Safety Act (ProdSG) we explicitly refer to these dangers. In the event of damage, legal problems can be expected.
Luminaires are subject to a number of external influences. Under certain circumstances, this can mean harsher operating conditions for luminaires which have an effect e.g. on the service life of the luminaires and lamps. Such effects may result in warranty limitations and even loss. The manufacturer should be asked directly about the effects of such special operating conditions on the luminaires. The following represents a short overview with selected examples.
Regiolux luminaires are designed for a sinusoidal alternating voltage of 230 V and 50 Hz (see fig. 8.6.). In other cases (e.g. foreign countries), ballasts must be adapted to the actual values of the supply voltage. For this reason the existing network construction and its values/tolerances must be regarded. This also applies to network deficiencies. In particular, overvoltage may lead to damage of the components in extreme cases. Sources of interference must be eliminated, if necessary together with the power supply company.
Electromagnetic compatibility (EMC) is defined by both interference immunity
of the luminaires against external disturbance factors and emitted interference to external systems. Various standards define corresponding limitation values. Despite conformity to these limitation values, in particular cases disturbances may occasionally occur (e.g. radio transmission). In such cases, interference immunity of the electrical devices should be inspected. Possible actions for
avoidance of disturbances are increasing the distance between the luminaire
and electrical device or modification of the wave band for signal transmission.
Regiolux luminaires are designed for an ambient temperature of 25° C (see fig. 8.6.). If in practice the ambient temperature strongly differs (e.g for cold stores or workshops with process heat), we should be contacted for specifying to what extent the selected luminaires can be approved for the corresponding temperature conditions. In particular, operation under higher ambient temperatures may lead to malfunctioning of e.g. the electronic ballast (see fig. 7.1.2.). In this case special luminaires may be required.
Environments with particular chemical substances in the atmosphere can have a range of effects on lamps, luminaires and lighting systems.
The resistance table gives an overview of the chemical stability of the most important plastics used for luminaire construction. Specifications for chemical resistance are related to an ambient temperature of approx. 22° C.
For cleaning of the diffuser/housing it is recommended to use a weak solution of the suitable agent. Limited use of chemical cleaning agents is allowed.
Under certain circumstances, chemicals may also have an influence on electronic components, circuit boards and LED. For example, luminaires with electronic components and PCBs can be damaged due to increased concentrations of ammonia in the atmosphere.
LED can also be sensitive to chemical influences. For example, atmospheres with an increased proportion of sulphur compounds or chlorides are considered critical and can result in occlusions, discolorations and reduction of the service life.
A precondition for the installation of our luminaires is that the ceiling construction is able to take up the weight of the luminaires and is also suitable for their accommodation.
Please note that luminaires can be incited by sound waves to emit resonance. Furthermore, noises caused by lamp and ballast operation can be emitted by
luminaires, and in addition thermal expansion until maximal level may cause
noise. If luminaires are to be deployed in areas of noise sensibility (recording studios, rehearsal rooms, sacral areas etc.), we request that you contact us
in this matter.
In the combination of LED and spot lens, the effective area of the lens is only located over the LED light points themselves and not over the entire circuit board. Spot lenses made of PMMA (acrylic glass) have a special, light technology calculated structure whereby the light is focused, emitted and distributed. Spot lens deliver a particularly efficient form of light control with a high degree of efficiency and optimised all-round glare control. The light distribution can be wide, narrow and extremely narrow (high-bay warehouse aisle lighting). A double asymmetrical light distribution curve is also possible. The latter is preferred in sales rooms such as discount stores or specialist markets and using vertical lighting levels it allows goods to be selectivly illuminated from both sides of the sales aisles. Industrial applications of the symmetrically distributing spot lens luminaires can be found in factory halls and warehouses. The LED is maintained as a visible light point in the appearance of the luminaire.
This type of lens made of PMMA (acrylic glass) is the preference for light technology of linear LED modules. Linear lenses have a special, light technology calculated structure whereby the light is focused, emitted and distributed. Linear lenses deliver a particularly efficient form of light control with a high degree of efficiency. The light distribution can be wide, narrow and extremely narrow (high-bay warehouse aisle lighting). A double asymmetrical light distribution curve is also possible. The latter is preferred in sales rooms such as discount stores or specialist markets and using vertical lighting levels it allows goods to be selectivly illuminated from both sides of the sales aisles. Industrial applications of the symmetrically distributing linear lens luminaires can be found in factory halls and warehouses. The appearance of the linear lens is perceived as a light line.
This lens is characterised by a special design with a grooved structure. Developed as a linear lens, the design is reduced to a pane made of PMMA (acrylic glass) calculated by light technology and is used in LED luminaires among other things. The light is bundled and focused via different angles of refraction, whereby asymmetrical distributions are also possible. This is used for example for furniture luminaires for cove lighting or for lighting of vertical areas.
This high quality plastic pane made of PMMA (acrylic glass) has light technology calculated pyramid prisms. This pane is characterised by homogeneous light distribution and excellent glare limitation, and is also appropriate for the illumination of VDU workstations with a light density threshold < 3000 cd/m2. In combination with LED, the individual LED light spots remain visible and the luminaire is also perceived as LED luminaire when switched on.
Diffusers can be designed either as panes or in a tub shape. PMMA (acrylic glass) or polycarbonate are used as materials; in harsher industrial applications the panes can also be made of single-pane safety glass. The optics are categorised as clear, clear with a prismatic structure, iced (satined) and opal. The light technology of the covers differs in terms of the degree of transmission and also in the efficiency level. Especially iced and opal designs provide a calm and unifying finish to the luminaires. For example, quadratic recessed luminaires have an effect of roof lighting. Angular diffusers have lit side sections and in this way generate an indirect proportion for modest ceiling illumination. Example applications are administration rooms without screens, classrooms, sales rooms and industry.
Luminaire louvres are composed of metal components and consist of louvre side sections and transverse lamellars. The side sections influence the light distribution of a luminaire depending on their shape and ensure transverse glare control, while the lamellars are primarily used to control longitudinal glare. High quality louvres are made of parabolic aluminium louvre elements, whereby the surface is anodised as either highly reflective or silk matt. Special designs such as the micro louvre with low transverse lamellars allow very flat luminaires and they have a supplementary reflection enhancing silver coating. The high degree of efficiency that is therefore possible combined with exact glare limitation produces a very comfortable level of lighting for vision, for example for VDU workstations. The luminance above the threshold emission angle of 65° is therefore reduced to <1000 cd/m2. Disruptive reflections on screens are avoided. Other application areas are representative spaces such as meeting rooms, conference rooms and reception areas. Specular louvre luminaires can also asymmetrically radiate light and illuminate vertical surfaces such as blackboards or presentation surfaces - if necessary with asymmetrically arranged lamp positions.
Simple louvre versions with white surfaces are used in spaces with lower light technology requirements, for example in corridors and waiting areas.
In order to maintain light output ratios, regular cleaning of luminaires is intended and makes sense. Lighting technology often features high-grade optical surfaces and must therefore be handled very carefully. Both mechanical loads (wiping, rubbing etc.) as well as the use of unsuitable cleaning agents must be avoided, as both can lead to impairment or even destruction of the optical characteristics of surfaces (see figure 8.1.7.). Residues of cleaning agents may furthermore cause smudges and streaks that might negatively effect light control. We would be glad to give you detailed information concerning the proper cleaning of luminaires.
Special versions with electrical or mechanical modifications as well as special coatings in accordance with RAL colours can be supplied at extra cost following assessment of feasibility. Customized luminaires undergo the same inspections at Regiolux as standard luminaires.
All Regiolux luminaires are manufactured according to approved technical standards and 100% electrically tested. The luminaires are designed as standard for 230 V, 50 Hz and an ambient temperature of 25° C, and satisfy European norms and directives, including ENEC provisions in relation to safety, electromagnetic compatibility and energy efficiency.
