1. INTRODUCTION
This specification covers the requirements for application of LED Star Board Holder for use in direct lighting
applications (such as office, automotive, communications, and architectural). The star board holder is designed
to house and provide electrical interconnection and thermal solution for a high–power LED star printed circuit
(pc) board light source. The star board holder consists of a heat sink, locking ring, and contact carrier
assembly. A thermally–conductive pad (available separately) or thermal grease must be used for assembly. A
diffuser lens is available separately as an option. Snap–on adapters for commercial fiber optic lenses and light
pipes are also available separately. Soldering or thermally–conductive adhesive is not required for assembly.
The star board holder is capable of two–contact loading for single–color LEDs and three– or four–contact
loading for full–color (RGB) LEDs (common anode or common cathode). The contact carrier assembly and
heat sink are marked with A, B, C, and D to reference the polarity of the LED to ensure proper orientation in
the lighting fixture.These star board holders are designed to be used with an Underwriters Laboratories Inc.
(UL) Class 2 power supply.
When corresponding with personnel, use the terminology provided in this specification to facilitate your
inquiries for information. Basic terms and features of this product are provided in Figure 1.

3. REQUIREMENTS
3.1. Material
The contact carrier assembly and locking ring are made of polybutylene terephthalate (PBT). The contacts are
made of copper alloy plated with tin. The heat sink is made of cast aluminum. The available lens is made of
polycarbonate.
3.2. Safety
Do not stack product shipping containers so high that the containers buckle or deform.
3.3. Limitations
The star board holder is designed to operate in a temperature range of –40
_
to 85
_
C [–40
_
to 185
_
F].
3.4. Storage
A. Shelf Life
The star board holder should remain in the shipping containers until ready for use to prevent deformation
to the contacts. The assemblies should be used on a first in, first out basis to avoid storage contamination
that could adversely affect performance.
B. Chemical Exposure
Do not store the star board holder near any chemical listed below as they may cause stress corrosion
cracking in the contacts.
Alkalies Ammonia Citrates Phosphates Citrates Sulfur Compounds
Amines Carbonates Nitrites Sulfur Nitrites Tartrates
3.5. Thermal Performance
The thermal performance of the overall system is paramount to the life of the LED. The star board holder
supports 1 to 4 watts of input to the LED without using forced air cooling or additional heat sink. IT IS
IMPORTANT that the thermal management is adequate for the specific LED and lighting fixture used. LEDs
with higher wattage rating can be used if forced air cooling or additional heat sink is employed.
3.6. Customer Supplied Components
A. LED
The star board holder is compatible with hexagonal “star board” high–power LEDs measuring 19.9 [.783]
across the hexagonal flats and having a thickness of 1 to 2.5 [.040 to .01]. A sample reference star board
pattern is given in Figure 2.

B. Connections
The electrical connector tabs of the star board holder accept Ultra–Fast Series 110 fully–insulated
FASTON* cable assemblies.
C. Thermally-Conductive Pad or Thermal Grease
A thermally–conductive pad or thermal grease must be used for assembly.
3.7. Assembly
The star board holder must be assembled using the following requirements:
1. A thermally–conductive pad or thermal grease must be placed into the hexagonal inset of the heat
sink.
2. The LED must be installed over the thermally–conductive pad or thermal grease. The polarity of the
LED should be oriented with the polarity reference markings of the heat sink.
3. The contact carrier assembly must be inserted into the heat sink with the polarity reference markings
aligned with polarity reference markings of the heat sink (A with A, B with B, C with C, and D with D).
4. The locking ring must be inserted into the heat sink and rotated using a long–nosed pliers or large
snap ring tool with right–angle tips so that it secures the contact carrier assembly.
5. If used, the diffuser lens and other optional components must be installed onto the locking ring.
6. The cable assemblies must be connected to the electrical connector tabs.
