Installation

2.1 Precautionary measures

Before installing LINEARlight Flex Diffuse, attention should always be paid to the following important issues:

ESD

Be aware that the products can be damaged by electrostatic discharge (ESD). Earthing is a very effective measure to avoid damaging effects due to electrostatic discharge. Therefore, use a personal earthing system (ESD field kit) during mounting to prevent the build-up of static charge.

Cleaning

Depending on the surface, use a multi-purpose cleaner, such as isopropyl alcohol, to provide a clean and dry mounting surface, which is free of oils, silicone coatings and dirt particles.

Mechanical forces

Avoid mechanical forces on the connector (feeder) and the LEDs. A strain relief is recommended. In addition, mechanical stress must not be applied to the LED module itself (e.g. no twisting or bending in excess of the allowed radius as shown in the next images from 1 to 3).

IP rating

The IP rating specifies the degree of protection against the intrusion of solid objects (including body parts such as hands and fingers), dust and water in electrical enclosures. While the first digit of the IP rating indicates the protection against foreign bodies, the second digit indicates the protection against water. For more details on IP rating, please refer to “Technical application guide – IP codes in accordance with IEC 60529 and external environment impacts” in the following OSRAM DS website section:

https://www.osram.com/ds/app-guides/index.jsp

The following IP rating applies to LINEARlight Flex Diffuse:

IP66: [6] Full protection against contact and penetration of dust
[6] Protection against ingress of water in case of powerful water jets
IP67: [6] Full protection against contact and penetration of dust
[7] Protection against ingress of water in case of temporary flooding

Note : Permanent submersion is not allowed.

Cutting

Ensure that the LED strips are cut properly at an angle of 90° before attaching the connector!

2.2 Connection with CONNECTsystem Diffuse

2.2.1 Basics

LINEARlight Flex Diffuse LED modules (TOP and SIDE) are compatible with the connectors dedicated for this product family. There are two components that can be used to power these LED modules:

Middle power feeder

This is the connector that connects the Flex Diffuse product to an LED driver. All LINEARlight Flex Diffuse LED modules are sold with already one of these connectors installed on the product. It consists of two parts:

• The transparent cage
• The white connector

Both parts are available either with the product FX-DCS-G1-CM2PF-IP67-0500 or with the KIT FX-DCS-G1-CM2PF-IP67.

Strip-to-strip middle jumper

This is a connector that connects two Flex Diffuse products when only one of these is powered by a 24 VDC LED driver. It consists of three parts:

• Two transparent cages
• One white jumper with two heads

They are available either in the product FX-DCS-G1-CM2PJIP67-0190 and in the KIT FX-DCS-G1-CM2PJ-IP67

LINEARlight Flex Diffuse LED modules are also available with pre-mounted wires. This option is described in the chapter “2.5 Custom versions”

Specially developed for LINEARlight Flex Diffuse LED modules, these power feeders offer great advantages for your installations because:

• The installation will be easy thanks to the low number (only 2) of components (connector + cage)

• The LED modules can be cut as needed (min. segment length that can be used with this connector is 10cm)

• Highly reliable connection

• Thanks to the transparent cage and to the special design that allows the electrical connection at the bottom of the LED module, this connector can be installed along the entire length of the LINEARlight Flex Diffuse LED module. The bottom side of each module is marked with a “scissors” symbol every 5 cm. This indicates the point where the LED module can be cut and where the connector can be installed.
  

• For longer installations where several LED modules have to be installed in series, the absence of a connector on the end allows to have a continuous and homogenous line of light without shadowing in between.
  

2.2.2 Mechanical dimensions

To have a clear indication about the space that each type of connector needs in the installation, please have a look at the images below.

2.3 Assembly

2.3.1 Assembly with middle power feeder

1. Components for assembly:

• LINEARlight Flex Diffuse TOP or SIDE (LFD600S)
• Connector: Middle power feeder (transparent closing cage + white connector)

2. Use a box cutter to cut the LFD module at one of the “scissors” symbols on the bottom side.

3. The connector can be installed over any “scissors” symbol along the whole module. Once you have decided on the right point, slightly incise the transparent liner over the “scissors” symbol and remove 2cm of the liner material in both directions.

4. Insert the transparent cage as shown in the picture. It has to be centered with the “scissors” symbol.

5. Take the white connector and check that its polarity is aligned with the polarity indicated on the bottom side of LED module.

6. Hold the white connector above the transparent cage and gently press it down until you feel both sides close with a click.

7. Ensure that the “hourglass” mark is still visible but not completely visible.

8. To install the end cap, remove the protection tape from the end of the LED module. Insert the silicone glue into the end cap and then insert the LED module. Wait 20 minutes for the glue to dry before proceding with the installation. In case of a double-sided end cap, the process is the same for both parts of the LED strip.

9. Connect the LED module to the LED driver. Observe the correct polarity (red+/black-). Perform a final operating test

Please note: When connecting two LINEARlight Flex Diffuse LED strips with the connector, ensure that the same polarities are always properly connected to each other.

2.3.2 Assembly with strip-to-strip middle jumper

1. Components for assembly:
   — LINEARlight Flex Diffuse TOP or SIDE (LFD600S)
   — Strip-to-strip middle jumper (transparent closing cages + white bridge connector)

2. Cut the LED module as described in paragraph 2.3.1.

3. For each connector head of the jumper, follow the same mounting steps as described in paragraph 2.3.1, starting from point 3.

Please note: When connecting multiple LINEARlight Flex Diffuse LED strips in series, always consider the allowed power per single LED driver.

2.4 Installation with LINEARlight Flex Diffuse mounting system

System connection

3.1 Basic steps of system planning

1. Select the suitable LINEARlight Flex Diffuse LED module with regard to your application and its requirements (level of light output, bending direction, etc.).
2. Determine the required level of control for the application (dimming, control interface, etc.).
3. Determine the number of LINEARlight Flex Diffuse LED modules and total wattage to be installed.
4. Consider all possible limitations of the setup: Cable lengths (for this, please have a look at the application guide for OPTOTRONIC constant-voltage LED drivers and at the technical documentation available for each OT CV device), thermal load, mechanical forces, ambient conditions and all other factors that may occur in a certain application.

3.2 Standard connection

The electrical connection between the secondary side of the OPTOTRONIC LED driver and the LINEARlight Flex Diffuse LED module must be IP-rated. Therefore, a clamp with an appropriate IP rating has to be applied.

Note:

For further information, please see the datasheets of the OPTOTRONIC LED drivers.

3.3 Parallel and series connection

If multiple LINEARlight Flex Diffuse LED modules are connected to one LED driver, they must be connected in parallel as shown in the image below.

Series connection, made possible by using FX-DCS-G1- CM2PJ-IP67-0190-X5, is allowed. However, the connection of different LED modules to the ECG must be done carefully, without exceeding the maximum operable length of LED modules (the product length is a technical information available on each technical datasheet or specification sheet of each LFD product).

Example:

LFD400S-G2-xxxx-10 is a 10-m product. A section of 3m can be connected with another one of 7m (10m in total), as shown below:

However, more sections cannot be connected in series if the sum of their lengths is longer than the maximum operable length of the standard product.

3.4 Temperature

For final application, it is important to check if the case temperature tc of the product is lower than the maximum declared value. An ambient temperature change during the day (due to, for example, a different sun exposure or the turning on of a heating system) can in fact influence the tc value when the LED module is on. For this reason, it is required to measure the case temperature at the tc point in the worst possible conditions of the installation. Where to measure the case temperature tc and the respective maximum temperature values are shown below:

Flexessories

To support the installation of Flex LED strips, a whole range of Flexessories – dedicated accessories for
Flex LED strips – is available. Our new extended range of Flexessories facilitates a quick and easy installation.
