1. Product Description

(1) The products (7 different types of modules) are LED modules used for indoor lighting applications.

For more details, refer to Section 10 for the specific applications.

(2) The LG Innotek standard modules are to be mounted on or into a luminaire where an LED driver

may also be mounted on or into the luminaire.

Figure 1 illustrates an example of a combination of the modules and the driver.

In this example, the luminaire holds one LED light engine (LLE) and the LLE has four LED modules.

In practice, the luminaire may hold any number of LLEs with any number of LED modules and

LED drivers, while respecting the maximum current that the LEDs, the connectors and

board traces can support reliably.

(3) The final photometric performance of the luminaire is determined by the number of modules,

the output current from the LED driver, secondary optics/diffusers, and thermal dissipation.

Please refer to the module datasheets to analyze the performance of the respective

module types under various operating conditions.

3. Thermal Management

The Tc (Contact Temperature) point is the reference point for measuring the module temperature.

Leveraging Tc point measurements should be an important part of the luminaire design and

verification process.

Thermal management of the LED junction temperature (Tj) is one of the most critical factors for

the operation and the lifetime of the luminaire. The Tc point on the module must not exceed the

maximum allowable Tc values as shown in Table 1 for the normal operation and lifetime of the

luminaire.

The luminaire housing itself can serve as an appropriate thermal management solution for the

LED modules. If the luminaire has good thermal conductivity, the heat will be dissipated and spread

though the luminaire housing, which will decrease the Tc of the LED modules.

To allow for good thermal contact and to avoid mechanical stress and strain, the contact distance

between the LED module and mounting plate (Luminaire) should be less than 0.5 mm along the

length of the LED module.

In addition, aluminum is highly recommended for the mounting plate (luminaire housing) due to

its good thermal conductivity and reasonable cost.

To further reduce the Tc point and LED junction temperatures, the use of a thermal interface

material such as double-sided thermal tape, thermal grease or silicone pads is recommended to

remove the up to 0.5 mm air gaps.

Table 1. Allowable Maximum Contact Temperature

It is essential that a constant current LED driver be leveraged along with an appropriate amount of

thermal dissipation to maintain the junction and contact temperatures of the LED modules at an

suitable level.

The allowable Max. Tc in Table 1 is defined as the maximum contact temperature while respecting

the maximum module current (If) where the modules are still considered to be working under normal

operating conditions with the expected lumen maintenance characteristics.

For the case of the “LLFML31-11K*01C” product family, a thermal interface material and/or a

mounting plate should be leveraged to reduce the Tc point temperature to 65℃ or under.

6. Design Considerations for Secondary Optics

7. Design Considerations for Diffusers

Distance between LEDs and a diffuser

Secondary optics such as a lens or reflector should have a clearance of at least 1.0mm from

the LED module (including the LEDs and the connectors).

This is necessary for the functional isolation of the system to prevent short circuits, open circuits,

and physical damage to the components on the board.

Luminaire manufacturers are required to develop or acquire their own diffuser to improve the

luminance uniformity of the system. If multiple LED modules are installed in the luminaire,

a distance of 5.0mm is recommended between the LED modules to allow for a continuous

optical pitch of the LEDs.

If the distance between the LED and diffuser is too short, optical hot spots will be viewable,

which will negatively impact luminance uniformity. However, if the distance is too long, the size

and weight of the luminaire may increase, which may negatively impact cost. The factors for a

diffuser to affect the optimal distance between the LED and diffuser are material, thickness and

clearness (permeability).

8. Installation Instructions

8.1. Wiring

In the case of a system with multiple interconnected modules, the modules should be connected to

each other leveraging cables with the lengths and wire gauge outlined in this section and Section 8.1.

There are two implementation options for interconnecting the modules.

The first is a simple connection where the “OUT +” connector pole is connected to the “IN +”

connector pole and “OUT –“ connector pole is connected to the “IN –“ connector pole marked

on the PCB.

The other option also leverages the “opt.” connector pole to improve the current balancing from

module to module by reducing the impact of voltage loss from the wire resistance.

However, both options will generate a parallel connection.

8.2. Interconnecting Modules

Connecting the LED driver to the connectors on the LED module should be done with a wire gauge

of 18 ~ 24 AWG and strip length of 6 ~ 7 mm.

See the table and illustrations below for a summary of the specifications.

8.3. Connections with Standard Parallel Topology

• Connections with 4 LED modules (280x40)

The recommended length of cables for interconnecting the LED modules is summarized

in the table below. The purpose of these lengths is to avoid the blocking of the LED light

by the cable while respecting the recommended 5.0 mm spacing between the modules.

Configuration

Configuration

The use of the “opt.” connector pole improves the current balancing from module

to module by reducing the impact of the voltage drop from the wire resistance.

Screw Size Materials Min. Torque Max. Torque

Threaded / Tap-tite Screw M4Steel

Aluminum0.6 Nm 1.0 Nm

*Metal screw head diameter should not exceed 9.0 mm for electrical isolation.

The torque depends on the screw type and heat sink or luminaire material.

The screws should be tightened with a torque in accordance with the table below.

8.7. Screw Type and Torque

In order to prevent damage by mounting materials on the

surface of the PCB, the use of insulating washers is highly

recommended when fastening screws.

The electrically isolated layer on the board may be

compromised if washers are not leveraged.

In addition, the mounting materials must comply with

the relevant creepage and clearance guidelines.

8.8. Vf Binning

The LGIT modules are labeled and packaged in two different voltage bins, “O” and “T”.

Connecting modules with different voltage bins in a system may generate current imbalances

between the modules, which may create luminous flux, CCT and temperature imbalances since

the modules are interconnected in parallel.

To solve this problem, LG Innotek recommends that each system comprises of LED modules

from the same Vf bin. The Vf bin is indicated on the PCB, tray and box labels.

All LED modules packaged in a box are from the same Vf bin.
