INTRODUCTION This specification covers the requirements for application of High-Power LED Light Socket for AMP LIGHT GUIDES light pipes for use in direct lighting applications (such as office, automotive, communications, and architectural). The light socket is designed to house and provide electrical interconnection and thermal solution for a high-power LED star printed circuit (pc) board light source. The light socket consists of a locking ring, contact carrier subassembly, and heat sink. A thermally-conductive pad (available separately) or thermal grease must be used for assembly. The light socket only accepts AMP LIGHT GUIDES 10-mm light pipe (available separately). The locking ring has an orientation notch, the contact carrier assembly has a square detent, and the heat sink has orientation latches and a square pin -- these features ensure proper orientation for assembly. The light socket 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). Soldering or thermally-conductive adhesive is not required for assembly. This light socket is 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.

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. 3.2. Safety Do not stack product shipping containers so high that the containers buckle or deform. 3.3. Limitations The light socket is designed to operate in a temperature range of -40_ to 85_C [-40_ to 185_F]. 3.4. Storage A. Shelf Life The light socket 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 light socket near any chemical listed below as they may cause stress corrosion cracking in the contacts. Alkalies Amines Ammonia Carbonates Citrates Nitrites Phosphates Citrates Sulfur Nitrites Sulfur Compounds Tartrates 3.5. Thermal Performance The thermal performance of the overall system is paramount to the life of the LED. The light socket 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 light socket is compatible with hexagonal "star board" high-power LEDs measuring 19.9 [.783] across the hexagonal flats and having a thickness range of 1 to 2.5 [.040 to .01]. A sample reference star board pattern is shown in Figure 2. 2 of 5 Tyco Electronics Corporation Rev B High-Power LED Light Socket for AMP LIGHT GUIDES Light Pipes 114-13232 Sample Star Board" Pattern 2.5 [.10] 4 [.16] 19.9 [.783] R 1.6 [.063] 19 [.75] 14.2 [.56] Figure 2 B. Connections The electrical connector tabs of the light socket 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 light socket 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 star board LED must be installed over the thermally-conductive pad or thermal grease. 3. The contact carrier assembly must be inserted into the heat sink. The square detent of the contact carrier assembly must engage the square pin of the heat sink. 4. The locking ring must be inserted into the heat sink. The orientation notches of the locking ring must engage the orientation latches of the heat sink; then, the locking ring must be rotated using a long-nosed pliers or large snap ring tool with right-angle tips so that it secures the contact carrier assembly. 5. The light pipe must be installed onto the contact carrier assembly. Make sure that the reflector strip is oriented properly (the light is emitted from the side opposite the reflector strip). 6. The receptacles of the cable assemblies must be connected to the electrical connector tabs. Refer to Figure 3.
