LMH2 Series Design Guide

About this Design Guide This design guide is intended to provide luminaire manufacturers an introduction to the LMH2 series of modules. This design guide also provides critical design guidelines for successfully integrating the LMH2 into your existing and new luminaire designs. This guide includes information pertaining to all lumen levels and dimming capabilities of the LMH2 series of modules. •

For additional information please contact your Cree modules distributor or Cree sales representative as appropriate.



For technical information and support, visit us on the web at www.cree.com/modules or e-mail us at modules_ [email protected].



All dimensions are in millimeters unless otherwise noted.



Dimension tolerances are as follows: ◊ Angular: machined ± 0.5°, bend ± 1°. ◊ All inside bend radii equal the material thickness unless otherwise noted. ◊ One-place decimal number: ± 0.5. ◊ Two-place decimal number: ± 0.05.



3-D models (.STEP files) for the LMH2 light sources and optional heat sinks are available on the Cree website.1

Cautions •

Do not power on an LMH2 LED module when the lens is blocked, for example, when the module is face-down on a surface. Irreparable damage may occur and will void the product warranty.



The LMH2 light source must not be electrically connected to an energized driver, commonly referred to as hot plugging. Irreparable damage may occur and will void the product warranty.



Wiring and electrical information in this design guide is for reference only. All installations and applications of module-based luminaires are subject to the electrical, construction and building codes in effect in the final installation location. Installation by professionals having experience in the area of electrical lighting and formal inspection by the authorities having jurisdiction (AHJ) is strongly recommended.



Thermal characteristics of LMH2 LED modules are affected by the luminaire and by the conditions in which the luminaire is installed. Whether a heat sink is required depends on the final luminaire design and the operating conditions surrounding the module. All final luminaire products should be evaluated in actual worst case installation conditions. Thermal limits of the module components must be maintained for warranty consideration.



LMH2 LED module surfaces may be hot during operation. Take care during handling to avoid burns.



Cree recommends connecting the LMH2 sunset dimming LED module to a dimmer separate from the dimmer for an incandescent lamp. There are no safety issues with connecting an LMH2 sunset dimming LED module and an incandescent lamp to the same dimmer, however the two devices may dim to different lumen levels in response to a particular dimming adjustment. Connecting the devices to separate dimmers allows both to reach the same lumen level with the appropriate dimming input.

Failure to follow the design guidelines in this document may void the product warranty.

LMH2 Series Design Guide

Thermal Design LMH2 LED modules are designed to perform in a variety of environments and their expected lifetimes are highly dependent on their operating temperature. The LMH2 light source is designed to transfer heat away from the LEDs through the housing. When designing a luminaire that incorporates the LMH2 LED 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 LMH2 light source must not exceed 70 °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 will increase thermal performance in luminaire designs and help meet minimum expected lifetimes. A heat dissipation path is required; the LMH2 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 LED modules are affected by their thermal environment. Nominal lumen values are typical at a Tc of 55 °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 LMH2 LED module, based on current thermal loss testing technology, is estimated to be 0‑70 °C. Photometric testing should be performed in situ. Over-Temperature Protection The LMH2 light source contains over-temperature protection that shuts down the light source if the monitored temperature on the LED board exceeds safety limits. If this occurs, cycle the power to the driver to resume operation. If the module shuts down repeatedly, the thermal design of the luminaire should be reviewed. 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 cyanoacrylatebased products is at the discretion of the testing organization. Cyanoacrylate adhesives should not

Available Heat Sinks Cree designed two optional heat sinks for use with both the WhiteLight and Sunset dimming LMH2 light sources. These heat sinks, available from Cree, provide a simple and cost-effective method to improve the LMH2 thermal performance in various applications. Each heat sink attaches to the upper face of the module with four (4) screws, included in the purchase of the heat sink.6 Most luminaire designs, regardless of source lumens, require the additional heat dissipation that can be provided by a heat sink. The use of a thermal interface material between the LMH2 LED module housing and the heat sink can improve a luminaire’s thermal performance. 7

A luminaire manufacturer is free to develop a custom heat sink. Proper operation of the heat sink requires it to be mounted to the module with four (4) screws at 90°. Failure to follow this hole pattern may result in uneven cooling of the module and unpredictable thermal performance. Optional Heat Sink 17 - order code LMH020-HS00-0000-0000001 40

Environmental Design The LMH2 LED module is suitable for damp locations and is rated IP-20. If the LMH2 LED module is to be used in an outdoor luminaire classified other than “suitable for damp location; covered ceilings,” the luminaire manufacturer must ensure proper intrusion protection and appropriate regulatory-compliance testing.

Optical Design The LMH2 LED module is supplied with a lens to provide a uniform light source. To maintain the warranty and for proper performance, the lens and reflector cone must not be altered or removed from the LMH2 LED 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).



Possible changes in color characteristics (CCT, CRI).

Photometry IES (LM-63-2002) files and the optical source model for the LMH2 LED module are available on the Cree website.8

Safety Certification Together, an LMH2 light source combined with a Cree LED module driver is “suitable for damp locations; covered ceilings.” Final luminaire designs should go through safety certification as required, which is the responsibility of the luminaire manufacturer. ENERGY STAR® ENERGY STAR is a U.S. government-backed program that defines energy-efficiency standards for products. Qualification of the final luminaire design for ENERGY STAR certification is the responsibility of the luminaire manufacturer. The final luminaire must be submitted for testing to an independent, certified test facility. Cree can and will assist in the process by providing LM-80 component data for submission to ENERGY STAR. Note - If a luminaire incorporating the LMH2 3000-lm light source will be submitted to ENERGY STAR, a Tc maximum of 68 °C is required. Module Disposal LMH2 LED modules should be disposed of properly at the end of their useful lifetime in accordance with local regulations. The LMH2 LED module is classified as “Electronic Equipment.”
