LED light strip – continuous lighting

LUNORA® LED stainless steel handrail: Modular perfection for continuous stair lighting at FeNau

The lighting of staircases, walkways and escape routes presents architects, planners and metal fabricators with particular challenges. It is not just a matter of complying with standards, but of seamlessly integrating light into the building’s architecture. With the LUNORA® LED handrail system, FeNau offers an uncompromising, modular LED system solution [cite: 13] that has been specifically developed for continuous lighting [cite: 5]. Designed for classic round grooved tubes with a diameter of exactly 42.4 mm [cite: 14], this system combines a timeless stainless steel aesthetic with state-of-the-art lighting technology.

The LUNORA® system is no ordinary handrail component, but a highly complex lighting solution. It guarantees glare-free, absolutely uniform and, above all, continuous illumination [cite: 14]. Where spot lighting solutions cast shadows or create the ‘zebra effect’ on stair treads, LUNORA® creates a continuous band of light that brings maximum safety, excellent spatial orientation and a high-quality, minimalist aesthetic to any building project.

The technological innovation: asymmetrical lens technology

A common problem with standard LED handrails is uncontrolled light emission. Without precise directional control, the LED strip emits light vertically downwards. The result: the wall to which the handrail is mounted is brightly illuminated – often to the point of being dazzling – whilst the centre of the stair tread remains in semi-darkness. The LUNORA® system solves this problem with a state-of-the-art, integrated lens[cite: 31].

Inside the LUNORA® handrail, this specially calibrated lens ensures that the light emitted by the LED strip is not simply scattered, but is specifically focused[cite: 35]. The light is refracted asymmetrically and optimally directed across the entire length of the handrail at the perfect angle[cite: 14, 35]. The result is impressive: a significantly larger area is illuminated than with systems without a lens[cite: 36]. Even in complete darkness, every step edge, every landing and every obstacle remains clearly visible[cite: 36], whilst unwanted stray light on the walls is reduced to an absolute minimum. This is easier on the eyes and significantly increases safety.

Well thought-out down to the last detail: the 180° swivel profile made of aluminium

The LUNORA® system is based on a small number of components that are extremely precisely coordinated with one another[cite: 37, 61]. The absolute highlight and technical centrepiece is the multifunctional aluminium swivel profile[cite: 66]. This support profile, which sits inside the stainless steel grooved tube, resolves the space issues that often arise when using different LED protection classes.

The profile can be rotated by exactly 180°[cite: 76, 77]. This means that one side of the profile is precision-milled to fit the narrower IP00 LED strips (for dry indoor areas), whilst the other, deeper side accommodates the wider, water- and dust-protected IP65 LED strips (for outdoor use and damp areas) exactly[cite: 72, 75]. This means you only need a single mounting profile system for both indoor and outdoor applications. To ensure installation is as error-free as possible, the profile features precision laser-cut guide lines[cite: 73]. These guarantee the exact, centred positioning of the LED strips when they are glued in place[cite: 73, 86], which is essential for an absolutely straight and uniform light distribution.

Uniform light without compromise: the PMMA cover

Nothing disrupts the architectural aesthetic more than individually visible, glaring LED diodes reflecting off the floor. To prevent this, the LUNORA® system is finished with a special, opaque cover made from high-quality PMMA (polymethyl methacrylate)[cite: 37]. This diffusing cover not only protects the sensitive LED system from mechanical impact and dirt, but also acts as a highly efficient diffuser[cite: 37]. It diffuses the light from the individual diodes to such an extent that they merge into a single, flowing and absolutely uniform line of light. No visible light points remain[cite: 37].

Premium LED specifications for the most demanding requirements

FeNau relies on uncompromising professional-grade quality for the electronic components of the LUNORA® system[cite: 55]. The self-adhesive LED strips used operate at a safe 24 V DC low voltage[cite: 43, 67]. They are highly efficient and deliver an enormous luminous flux of 1,500 lumens per metre whilst consuming just 13.2 watts per metre[cite: 46].

To perfectly tailor the lighting ambience to your property, two carefully selected light colours are available[cite: 14]:

• Warm white (2700 K): Ideal for inviting living areas, restaurants, hotels or wooden staircases, where a cosy, warm atmosphere is the priority[cite: 39, 44].
• Neutral white (4000 K): Perfect for office buildings, hospitals, public facilities and modern concrete or stone architecture. This light colour maximises contrast and ensures the highest levels of alertness and safety[cite: 40, 44].

The strips are extremely versatile: they can be cut to length precisely every 50 mm [cite: 47, 85] and are supplied in generous lengths of 6,000 mm or even 25,000 mm for long flights of stairs [cite: 49]. Naturally, all electronic components are fully CE-marked [cite: 18, 50, 52] and RoHS-certified [cite: 50, 53].

Intelligent control and simple installation

The LUNORA® system can be seamlessly integrated into modern building management systems. The LED strips are fully dimmable and compatible with PWM (Pulse Width Modulation) controllers [cite: 48]. In combination with our Bluetooth-enabled and dimmable power supplies, the lighting system can be controlled intelligently via an app or push-button [cite: 14] to achieve the perfect brightness depending on the time of day or requirements.

For metal fabricators, LUNORA® means massive time savings during installation[cite: 56]. The support profile is secured within the stainless steel tube using clever fastening clips with a click mechanism[cite: 65]. These clips are screwed (M4 x 8) or riveted into the grooved tube at intervals of approximately 250 mm (at least two per section)[cite: 82, 83]. The fitted support profile is then simply and securely clipped into these clips[cite: 83]. The entire cable routing is concealed from view: cables are routed invisibly through the hollow handrail supports directly into the wall or along the groove in the direction of the supply cable[cite: 84].

Compliance with building regulations and support for lighting designers

Staircase lighting is subject to strict legal requirements, particularly in public spaces. The LUNORA® system was explicitly designed to assist architects in complying with these standards. It meets the high installation requirements set out in DIN 18040 (Accessible construction in public buildings and dwellings) [cite: 20, 24, 25] and DIN 18065 (Building staircases) [cite: 21, 26, 27].

To make the planning process as efficient as possible, we provide architects, planners and specialist trades with all the necessary data [cite: 114]. The LED system can be fully integrated into professional lighting design software [cite: 14]. We provide you with the relevant Eulumdat files, photometric data, as well as detailed CAD data and tender specifications [cite: 14, 114]. From the initial design phase in the office through to professional installation on site, the process becomes more precise and efficient [cite: 115].

Simple and safe installation: the LUNORA® installation steps

The LUNORA® system has been developed not only to impress visually, but also to offer maximum efficiency during installation by metalworkers. The modular system is assembled in just a few logical steps:

1. Cutting profiles and covers to size: The first step is to cut the slotted tube, support profiles, covers and the optional lens to size[cite: 80]. Measure the support profile, the cover and the lens precisely between the handrail brackets[cite: 80].
2. Prepare the fixings: Measure the positions between the handrail supports and mark out the corresponding drill holes[cite: 81]. Then mark out the threads or drill holes for the fixing clips – plan for one clip every 250 mm (but at least two per run)[cite: 82].
3. Fitting the clips and handrail fixings: Screw the fixing clips (M 4 x 8) in place or use rivets[cite: 83]. Secure the handrail brackets and simply clip the cut-to-size bracket profiles into place[cite: 83]. To route the cables, feed them through hollow handrail supports where appropriate and, if necessary, lay them along the groove in the direction of the supply cable[cite: 84].
4. Cutting and fitting the LED strips: Cut the LED strips to the exact required length at the marked cutting points (every 50 mm)[cite: 85]. Then degrease the profile thoroughly, align the LED strip, peel off the adhesive backing and press it firmly into place along the glazed guide lines[cite: 86].
5. Connecting the power supply: Fit the connectors and establish the connection between the supply cable and the LED strip [cite: 87]. Important safety note: The final connection to the mains must only be carried out by a qualified electrician [cite: 87].
6. Fitting the optical components: As a final step, slide in the optional lens and clip the PMMA cover into place for a neat finish[cite: 88].
