About the SLED Series

The SLED modules is engineered to allow lighting designers and luminaire manufacturers to quickly incorporate state-of-the-art LED technology into their luminaire designs. The SLED module is a complete LED lighting solution consisting of a light source and separate power supply. SLED light source incorporates an internal thermal management system with a compact form factor and can be available in two different configuration: FLAT and SINK. SLED modules are designed to be used in Outdoor but even in residential and commercial lighting applications where high efficacy and color rendering index (CRI) values are important.

A brief resume of sled series configurations available are summarize below:

Input and Output for SINK (n. 5 versions) and FLAT (n. 3 versions) available for both SLED x 4 - SLED x 9.

Electrical Design

All SLED modules, regardless their dimming capability, are performance-optimized to operate with CC (constant current) LED module drivers. Detailed driver and wiring diagrams required can be found in the SLED data sheet.

Table below shows the correspondence between the SLED light sources and the some commercial LED drivers. Selected and available from Castaldi Lighting. However, the 5-year warranty is extended to the SLED module only when it is used with an approved module driver or a third-party qualified driver. The Castaldi Lighting Technical Team can provides information on drivers compatible with SLED modules. [email protected]

The SLED module lead wires standard available are 500 mm long, 4 wires 0,5mm2 - 20 AWG with the ends stripped 10 mm.

Caution Do not connect a light source to a driver when the driver is energized, commonly known as hot-plugging. Connecting a light source to an energized driver can damage the light source and will void the warranty.

Protective Earth Ground The SLED module must be properly earth grounded. A secure electrical connection must be made between the cast housing or heat sink mounting screws and the luminaire’s protective earth ground connection.

Electrostatic Discharge No special electrostatic discharge (ESD) precautions are required for handling SLED modules in a production environment.

Dimmer Selection Standard Electronic low voltage (ELV) dimming controls have demonstrated repeatable and acceptable performance when used with SLED in test conditions. Traditional dimmable Constant Current (CC) Led driver unit can be used to dimmer SLED modules. Typical options available and advised for SLED dimming is DALI interface; anyway Castaldi Lighting recommends testing the complete luminaire (SLED + Driver + Dimming-Interface) to verify that its dimming performance is satisfactory.

Power Requirements for SLED Family Following are the electrical power requirements for a driver to operate the SLED module with the White and Dinamic option release.

Handling and Interconnection

The SLED module must be properly electrical and mechanical connecter to warranty the IP67 grade and electrical and optical performances. A secure mechanical-electrical connection must be made between the cast housing or heat sink mounting and SLED Electrical interconnection accessories available. To preserve and reduce critical aspects all SLED electrical slot available have to be manage in right manner, and so is strongly recommended: 1. Avoid to Assembly SLED units in dusted and pollution environmental

2. Remove all SLED cups protections only few instance before electrical interconnection

3. Avoid and be sure nothing will be present or could be introduce inside the side Slot SLED interconnections

4. Use for PLUG cable interface the mechanical security lock part

Electrical Interconnection

In order to warranty the IP67 interconnection and reliability ONLY SLED proprietary electrical accessory have to be used. 5-year

warranty is extended to the SLED module only when it is used with approved and official electrical SLED interconnections.

The SLED electrical configurations and accessories available for different configurations, are summarize below.

The electrical Interconnection accessories available are 4:

PSU – SLED Driver interconnection SLED is a Class III module and can be connected to a traditional constant current power supply. Both Class II and Class I can be evaluated and used in final configuration. The max distance advised between PSU and last SLED module (Power Supply Unit) is 15 m. All SLED are not protected to reverse electrical polarization, only the SLED connectors warranty the right installation and preserve the correct installation concept. Final user have to pay attention to the Input cable, for both bottom model and side connector model, have to be correctly connected to POWER SUPPLY in order to power on the chain and avoid to damage the SLED units.

Interconnection Cable Configuration have to be:

Red Cable = Anode Led W1 Black Cable = Cathode Led W1 Green Cable = Anode led W2 Blue Cable = Cathode led W2

The LED W1 Channel is traditional White configuration for standard WHITE model, the Channel W2 will be available and connected Only for Dinamic White configuration

In general Is strictly recommend in PSU choice to use the Class I in order to have a more strike and surge resistance and immunity (in particular in outdoor applications)

After PSU selection, the SLED configuration and relative single code identification have to be correctly and carefully fixed. In figure Z is summarized the tipical SLED configuration in order to stay in SELV concept. This configuration is only for reference; it’s possible configure SLED modules in order to connect more modules and use a different PSU in order to stay out to SELV concept and have a more competitive cost configuration: in that case an accurate electrical assembly and design have to be followed we advise to contact our team for more details: [email protected]

The right SLED code identification and right SLED module configuration can be supported by our staff. We advise to contact our team and provide him the idea of your interconnection and configuration required.

Check Imax to ensure Tc (Temperature control)

Generally the SLED Electrical platform concept can be resumed in: 1. Constant current Led driver 2. SLED Interconnection Cable option (From driver to First SLED module)

a. Side Cable interconnection b. Bottom Cable integrated in first SLED module

3. SLED Chain configuration (always 1 Input and 1 Output) a. Invisible SLED interconnection b. Plug-Plug SLED cable Interconnection

4. SLED Module Terminator *

Concept of SLED Freedom Interconnection

Wiring Strain Relief SLED modules must not be suspended directly by the leads. Though the wiring from the SLED light source is internally strain relieved, additional strain relief methods must be employed if the luminaire is to be suspended solely by the wiring, as in a pendant luminaire. It’s strongly recommended use accessories available on catalogue to realize mechanical fixing.

Thermal Design

SLED modules are designed to perform in a variety of environments and their expected lifetimes are highly dependent on their operating temperature. The SLED Aluminum engine is designed to transfer heat away from the LEDs through the housing. When designing a luminaire that incorporates the SLED module, careful consideration must be taken to ensure a sufficient thermal path to ambient is provided. Verification of a proper thermal path is done through the placement of a thermocouple at the specified Tc location. The SLED light source must not exceed 75 °C at the Tc point in thermal equilibrium to ensure proper performance and expected lifetime and to maintain warranty terms. The use of a heat sink Option, recommended for instead of Flat option, will increase thermal performance in luminaire designs and help meet minimum expected lifetimes. A heat dissipation path is required; the SLED family of modules should not be operated without a properly tested heat dissipation path. Luminaire designs with a direct thermal path to ambient are desired and will provide the best results. LEDs and SLED modules are affected by their thermal environment. Nominal lumen values are typical at a Tc of 60 °C and subject to a build tolerance of ±10%. As the Tc rises, the optical performance of the module decreases. The acceptable Tc operating range of the SLED module, based on current thermal loss testing technology, is 0-75 °C. Over-Temperature Protection The SLED light source don’t contains over-temperature protection that shuts down the light source if the monitored temperature on the LED board exceeds safety limits. To achieve this option is necessary use a dedicate led Driver with NTC or similar input option and connect to Tc point a Thermocouple; SLED could be available with this additional NTC sensor on board : For additional info please contact the Castaldi team directly at [email protected] Ambient Temperature Measurement The ambient temperature of the test environment must be monitored and recorded with the required data during a temperature test. The preferred ambient temperature measurement apparatus is described in UL1598-2008 Rev January 11, 2010, Section 19.5. The intent of this requirement is to ensure that the temperature monitored does not fluctuate. The ambient temperature of the space must be 25 °C ± 5 °C. Note that bare thermocouple wires in open air is not an acceptable method of recording the ambient temperature. Thermocouple Attachment Method Attach a thermocouple to the indicated Tc location. The attachment method described in UL1598-2008 Rev January 11, 2010, Section 19.7.4 is preferred; using silver-filled thermal epoxy is an acceptable alternative. Ensuring that the tip of the thermocouple properly contacts the module at the Tc location and that the attachment method does not add thermal resistance to the test is critical to correct and acceptable testing. Note - Quick-drying adhesives and other cyanoacrylate-based products are known to be destructive, over time, to the components and adhesives used in solid-state lighting products. The use of cyanoacrylate-based products is at the discretion of the testing organization. Cyanoacrylate adhesives should not be used in any luminaire design or for any long-term testing. Tc Measurement Method Once the thermocouple is properly attached at the Tc location, assemble the module into the luminaire. The luminaire must then be tested in its intended environment or that environment which will result in the highest recorded temperature. Take care during assembly to ensure that the thermocouple remains properly attached. Energize the luminaire and allow the assembly to reach thermal equilibrium. Thermal stabilization may require up to 7.5 hours, depending on the mechanical design. Once thermal equilibrium is achieved, record the room ambient and case temperatures. Acceptable test results require the ambient temperature to be between 20 °C and 30 °C (25 °C ± 5 °C). Recorded variations above or below 25 °C must be added to or subtracted from the recorded temperatures. The table below can be used to determine the expected luminaire operating life.

Expected SLED Lifetime versus Temperature at Tc Point

>50,000 75

>80,000 60

Example of SLED Lifetime shift vs Ta @ 700mA driving

(with air flow null and without any mechanical heatsink fixing support)

In order to satisfy the Lifetime product data the TC have to be preserved; two way are possible to achieve this target:

1. Maintain the Ta (ambient) under control in order to have the SLED Tc below the Max value of 75°C 2. Modify the Max current of SLED in order to have the SLED Tc below the Max value of 75°C

Caution

SLED module surfaces may be hot during operation. Take care during handling to avoid burns.

In addition be sure to fix the SLEDs in appropriate environmental conditions: Fixing accessories Materials and Air space design have to be carefully selected.

Environmental design

The SLED module is suitable for damp-wet locations and it is rated IP-67 only if used with relative interconnection accessories available. If the SLED module is to be used in an outdoor luminaire the luminaire manufacturer must ensure proper intrusion protection and appropriate regulatory-compliance testing in particular he have to pay attention to correct cable fixing position and if possible to block the SLED cable in order to warranty the join stability of SLED connectors.

The two main important actions have to be followed using SLED platform are: 1. Check the final application:

a. Verify presence of chemical conditions b. Verify the temperature range (operative and not) c. Verify the application request: Mechanical fixing and accessories can impact of SLE lifetime

2. Check the Accessories requests and verify the compatibility of them: a. Verify the useful led driver to be used (IP rating and current selection) b. Verify if the topology of installation is proper for Accessories Kit selected

Optical Perfomances

The SLED module is supplied with a integrated cover-lens to provide a uniform light source. To maintain the warranty and for proper performance, the lens must not be altered or removed from the SLED module. A secondary optic is not required. If a secondary optic is used, the following trade-offs may occur:

Reduced light output (luminous flux).

Reduced efficacy (lumens/watt).

Photometry IES (LM-63-2002) files and the optical source model for the SLED module configurations are available on www.castaldilighting.it/ Optical materials Choice

Optical choice have to be followed in order to match the best trade off between optical performances and final environmental application; this is why in order to satisfy different applications and constraints, two different plastic optic material options are available:

The first (PMMA) is suitable for applications where high efficiency performances is a MUST and no high impact resistance is

required. In fact this material present a good resistance to thermal shock temperature , excellent resistance to wear caused

by inclement weather and ultraviolet rays and chemical agents but poor heat resistance. Especially for extreme ambient

conditions and exposure to chemical substances in industrial production facilities, a PMMA optic was developed that is highly

durable even in atmospheres frequently containing oil. The flat surface of optics present to final user the plus: easy-to-clean

.

The second (PC) is suitable where high impact resistance is a requirements and/or constraints, this configuration has even a

higher thermal resistance ; drawbacks are polycarbonate is scratched due to its low hardness superficial and presents little

resistance to atmospheric agents and ultraviolet rays. The PC optic is perfectly suitable for use in industrial areas without

exposure to chemical substances.

* For any doubt or other verifications about final compatibility of two different materials please see Castaldi Lighting website or contact our team [email protected]
