Smart Textile Illuminated Apparels FAQ
There are various options for integration, depending on your needs and fittings. Most of our customers insert a piping and run the light module through. Sewing flaps are installed on each side of the driver and splitter unit, as well as on the LED modules to make integration as easy as possible.
Our light guides are very flexible and with a diameter of 3mm, comparable to a phone charging cable. You can bend up to a 3cm angle without having an influence on the light quality.
Yes, it is. Please always remove the power bank before washing! The light module can only be washed when disconnected from the power supply. Once integrated you can wash your garment including the light module at up to 60°C/ 140°F.
Yes, it is. Please always remove the power bank before drying. The light module can only be dried when disconnected from the power supply. Once integrated you can dry your garment including the light module at up to 90°C/ 194°F is possible.
The aramid piping protects the light module and allows it to pass the FR test. Therefore, the light modules are suitable for integration in firefighter uniforms. The light module without any protection is not fire-resistant.

In theory we could make our light brighter but that would require product development, testing and certification which means it is not something we could do in short term. The current system is balanced, and any changes could result in changes of lifetime or product dimensions. When Osram developed the light system, various testing has been done and the current brightness has been developed. The brightness is effective in terms of visibility range and acceptable for the wearer – if the light is too bright there is a risk of blinding the wearer and others next to him. That´s relevant in cases where people are wearing an illuminated garment throughout the complete working days. We are part of the German committee which develops a norm for active illumination in PPE and there will be a maximum brightness specified to address this issue.
It does not make sense to measure brightness of such light systems in Lumen. The light is illuminated through a translucent light guide which spreads the luminous flux and ensures homogenous illumination throughout the light guide. The committee which develops the norm for active illumination is discussing this as well and it is clear that Lumen will not be specified in this norm, it will be rather cd/lx/sqm, similar to what is being used to measure retro-reflection.
Visibility (on how many kilometers are you visible with this LED-light) depends on environmental conditions (humidity, rain, fog, etc.) There is no standard test method available at the moment to measure the visibility range.
5 to 8 hours with a 2 light guide system. Permanent light will be closer to 5 hours and flashing rather 8 hours. These measures are related to the OSRAM Power bank with 2.500 mAh
Our major focus is, to keep people safe. The European Union is already discussing the implementation of active illumination in their regulations. As some car headlight systems blank out moving objects, reflective tape is not enough anymore. Active illumination is essential to assure future safety of your employees. If is necessary to mark the goods as dangerous goods with regard to transport guidelines.
Product lifetime, washing cycles and light output apply according to this OSRAM product specification. The product lifetime L70/B50 (50% of the light modules can drop down to 70% of the initial specified light output of a new module) is 2.500h and 20 washing cycles according to the standard lifetime as explained in IEC 62717. The decrease of the light output depends on the usage, cleaning procedure and cleaning agents, which degrade the light emission capability of the light guide.
A full waterproof jacket is possible if the light system is integrated in a layer between inner and outer jacket (Using a membrane is a possibility) We have some ideas please contact your sales partner.
