General questions
● 24V systems work with half the current of 12V systems, reducing heat and current losses, leading to increased lifespan.
● Lower current and higher voltage allow longer ribbons with minimal voltage drop.
● Lower energy consumption means lower operating costs.
● Focusing on a single system significantly reduces stock size for products and accessories as well as to faster product availability.
● Jedver 24V LED-ribbons feature more LED chips than standard 12 V LED-ribbons and can be cut to any size without loss of bright ness, even the corners are brightly lit.
General questions to light
● Note the requirements that the luminaires in this room must meet. A different type of lighting may be required in the bedroom than in the kitchen or living room. Depending on what you do in the room, different light is required. “Layered light” is a tried and tested way of perfectly illuminating a room. Layered light offers perfect illumination of the room and an atmospheric ambience thanks to a harmonious mix of basic, accent and ambient lighting.
▷ Basic lighting: uniform, very diffuse light that illuminates the entire room.
▷ Accent lighting / zone lighting: brings light to where it is needed; sets accents; creates zones within a room.
▷ Ambient lighting: discreet, warm light; creates atmosphere; sets the scene in the room.
● Important aspects of Human Centric Lighting:
▷ Adaptation to the natural day-night rhythm: HCL systems mimic the changes in natural daylight by adjusting the light colour and intensity throughout the day. Cool, energizing light is often used in the morning, while warmer, relaxing light is used in the evening to support the natural sleep-wake rhythm.
▷ Consideration of biological needs: The light is designed to support people's biological rhythms, leading to better sleep patterns, increased alertness and improved well-being. This is achieved by adjusting the colour temperature and light intensity.
▷ Improving productivity and mood: By using HCL, environments can be created that increase productivity and concentration by adapting the lighting conditions to the natural course of the day. It can also help to improve mood and reduce stress.
▷ Health promotion: HCL systems can help to prevent health problems such as sleep disorders and eye strain by optimally adapting the lighting conditions to people's circadian rhythms.
▷ Flexibility and control: Modern HCL systems often offer the option of adjusting and controlling the light using intelligent systems and sensors that respond to individual needs and preferences.
● The colour temperature describes the colour of the white light from a light source, measured in Kelvin (K), and indicates whether the white light appears warm (yellowish) or cold (bluish). Colour temperature affects human mood, productivity, sleep quality and perception by shaping the atmosphere in a room and influencing people's biological and psychological well-being.
● Warm white light (< 3300 K): relaxing
▷ Creates a cozy, relaxing atmosphere that is often used in living rooms and restaurants. It can help to reduce stress and promote a relaxed mood. Ideal for relaxing activities in the evening or during leisure time.
● Neutral white light (3400 K - 5000 K): activating, energizing
▷ Promotes a productive and focused environment often used in offices and workspaces. It can improve concentration and alertness by simulating a natural daylight atmosphere.
● Cool white (daylight white) light (> 5000 K): enhances concentration
▷ Has a stimulating effect that can increase alertness and energy. It is often used in areas that require high precision and attention, such as workspaces and laboratories. Can reduce fatigue and increase performance, especially in the morning hours or when working at night.
● LEDs can be divided into the following systems:
▷ Monochrome white: LEDs that produce a specific colour of white light; the colour temperature cannot be varied.
▷ Multiwhite: LEDs that combine several white LEDs with different colour temperatures (e.g. warm white, neutral white, cool white) to enable a variable light colour and temperature and thus offer a more flexible lighting solution.
▷ RGB (red, green, blue): LED illuminants that produce a wide range of colours by combining red, green and blue light in variable intensities using additive colour mixing. RGB LEDs can also mix white light.
▷ RGB monochrome: LED light sources that combine both RGB colour-changing LEDs and white LEDs with a specific colour temperature to enable a comprehensive range of colours and flexible light temperature control. White light is not produced by mixing red, green and blue colours, but by separately controlled white LEDs. The result is a “more perfect” white than is possible by mixing red, green and blue.
▷ RGB multi-white: LED light sources that combine both RGB colour-changing LEDs and several white LEDs with different colour temperatures to enable a comprehensive range of colours and flexible light temperature control. White light is not produced by mixing red, green and blue colours, but by separately controlled white LEDs. The result is a more “perfect” shade of white than is possible by mixing red, green and blue.
● Increasing distance leads to decreasing illuminance.
● A small beam angle produces a focused beam of light with high illuminance, while a wide beam angle produces a wider light cone with less illuminance.
● Although warm white and cool white light can technically have the same illuminance, cool white light mostly seems brighter than warm white light.
● The CRI evaluates the ability of a light source to display the colours of objects authentically and naturally.
● The scale ranges from 0 to 100, with 100 representing the best color reproduction, comparable to natural sunlight.
● So CRI 97+ is near to the colour rendering of daylight and so provides you with true colours.
General questions to installation
● The applicable national regulations must be observed. Installation and commissioning may only be carried out by a qualified electrician in some cases. The products may only be used for their intended purpose. The instructions in the installation and operating instructions must be observed. Modifications for which the products are not intended are not permitted. Non-compliance may result in damage to property and personal injury. Furthermore, the manufacturer accepts no liability in the event of non-compliance and the warranty becomes void.
● Our products use a user-friendly plug-in system that enables a quick and secure connection without extensive technical knowledge. This makes installation and maintenance easier.
● Technical support and further information is available from our customer service department. We also offer extensive information on our homepage and in our catalogue, including installation guides, product specifications and application notes.
LED-ribbons
● An additional power supply unit must be connected in between to ensure a constant voltage supply and thus prevent the brightness from dropping.
● Also suitable for short-term voltage peaks up to 16 V thanks to the integrated IC.
● This is why LED strips with constant current technology are ideal for ceiling lighting and lighting in caravans.
● COB LED-ribbons are characterized by a wide beam angle of 180° and homogeneous illumination without visible LED dots (without diffusor).
● The LED-ribbon and the driver must be suitable for use in wet rooms; information on this is provided by the IP protection rating. Depending on the distance to possible water sources, an IP rating of at least IP44 is required for wet rooms. Jedver silicone ribbons have an IP65 protection rating.
● In addition, silicone LED strips can also be installed in waves and circles due to the material properties of silicone, whereby a radius of at least 30 mm must be observed.
● The straight and 90° connectors are generally suitable for 12 and 24 V systems.
● For the connecting cables with connectors, it must be noted additionally to width whether they are 12 or 24 V.
● The diffusors ensures uniform lighting.
● It must be noted from how many LEDs /m the LED dots are no longer visible.
● Jedver diffusors have a high light transmission of 80 %.
