Circular Light Module (CN88) 408-10424

28 JAN 11 Rev A

Figure 1

1. INTRODUCTION

The circular Light Module (CN88), (part number

2154159-[ ]), is designed as a compact, self-

contained, easy-to-mount, plug-and-play circular

module to be used in both prototype and custom

production applications. This module is to be used

with the NEVALO* Interconnect System (refer to Tyco

Electronics (TE) Application Specification 114-13290).

The module can be used with the Straight and

Right-Angle NEVALO Connectors.

All numerical are in metric units [with U.S.

customary units in brackets]. Dimensions are in

millimeters. Unless otherwise specified,

dimensions have a tolerance of ±0.13 and angles

have a tolerance of ±2°. Figures and illustrations

are for identification only and not drawn to scale.

Bridgelux is a trademark.

2. DESCRIPTION

This module consists of a base with mounting

hardware, Bridgelux LED, PCBA with thermal

protection, Thermal Interfa ce Material (TIM),

protection cover, reflector with multiple beam angle

configurations (narrow and wide), and a snap-on top

ring. The module is available i n several configurations.

See Figure 1.

3. ASSEMBLY PROCEDURE

The module must be assembled by a qualified

electrician in accordance with national and local

electrical codes and the following instructions.

3.1. Heat Sink Mounting

The thermal management of the overall system is

critical to the life of the LED. It is very important that

the thermal management is adequate for the LED

lighting fixture being used. For more detailed

information, refer to Application Specification

114-13300.

Figure 2 shows a properly sized heat sink mounting

pattern. F or low volume production applications of the

CN88, TE of fers a T ransfer Punch Guide (part number

2154454-1) to assist in the making of the heat sink

mounting hole drill locations. See Figure 2.

3.2. Mounting the Circular Light Module (CN88)

1. Once the heat sink has been properly sized and

prepared for the application of the Circular Light

Module (CN88), the base sub-assembly (base

housing, screws, protection cover, PCBA, LED, and

TIM) can be aligned over the mounting holes.

Mounting screws to be alternately tightened to a

torque of 0.28 to 0.45 Nm [2.5 to 4.0 in.-lbf]. See

Figure 3. The protective cover can now be removed.

When mounting the module, care must be taken

not to damage the light module and LEDs with the

screwdriver used for tightening the mounting

screws. The protection cover is protecting the LED

during this operation.

If the clear protective layer on the TIM material is

not removed, optimum thermal performance will not

be achieved.

2. The reflector is then installed, aligning three

keyways. Reflector posts have a slight click-fit into

the light engine holes. Firmly seat the optic in place.

See Figure 4.

TE recommends that when handling the reflector,

that non-marking gloves be used. The reflector

should be handled by the outer diameter to

eliminate the chance of leaving marks within the

light emitting area.

3. The top ring (with compression ring

pre-assembled) is then lowered over the light

module, aligning three (3) pegs in the top ring to

three (3) guide features in the base. With a slight

downward pressure (t o compress the compression

ring and a clockwise twist), you will feel and hear a

tactile an d audible click. This secures the top ring

on the Circular Ligh t Module (CN88) and completes

the assembly. See Figure 5. Refer to Application

Specification 114-13290 for information on

assembly procedures on the NEVALO Interconnect

System.

4. After the Circu lar Light Module (CN8 8) is secured

to the heat sink, the mating NEVALO Cable

Assembly can be mated to energize the module.

The Circular Light Module (CN88) will accept the

Straight and Right-Angle NEVALO Connectors.

Straight is shown in Figur e 6.

4. REPLACEMENT AND REPAIR

Circular Light Module (CN88) components are not

repairable. If it is evident that a component is

damaged, it must be removed and replaced with a

new component.
