STRADA-2X2 INSTALLATION GUIDE

The following instructions should be observed before using the product to ensure reliable assembly. Fastening can be done by using screw, tape or adhesive. Recommended operating temperature (PMMA) is -40°C to +80°C.

1. Heat sink machining 2. PCB Layout 3. Screw requirements 4. Assembly 5. Fastening

1. HEAT SINK MACHINING

Cable holes and screw thread holes must be done before lens assembly.
Ensure that anodized heat sink surface is even
Correct thickness of the PCB is 1.6 mm (position pin lenght 1.1 mm)
Screw thread hole accuracy is +-0.1 mm
Screw vertical straightness tolerance is +-⊥0.1 mm A

2. PCB LAYOUT

Minimum of two (2) position pin holes are needed for accurate lens assembly, depending on the desired direction of the lens
If fastened with screws, at least one (1) is needed to attach lens from the middle, other four (4) places on the sides are optional
Recommended width for position pin holes is 2.10 mm (-0 mm +0.1 mm)
One of the pin holes is oblong shaped, for the plus pin is for alignment and the minus pin prevents the lens from twisting

3. SCREW REQUIREMENTS

STRADA IP2x6 lens attachment screws are of type M3. (DIN 7985, ISO 7045/ISO 14583 TX)
Countersunk screw is not allowed
Self-tapping screws are not recommended

4. ASSEMBLY

Optimal distance between STRADA-2X2 lens modules is 50.8 mm, so that the same spacing (25.4 mm) continues between optics
It is recommended to calculate the spacing using the position pin holes

5. FASTENING

Fastening can be made either with using screws, tape or adhesive Please note: Like all PMMA lenses STRADA-2X2 is also prone to environmental stress cracking. Please make sure that chemicals used in the fixture manufacturing do not cause stress cracking risk with PMMA.

SCREWS

Maximum tightening torque for the center screw is 0.6 Nm
At least one screw (1) is needed to attach the lens from the middle, other four (4) places on the sides are optional
Tightening torque for the four (4) optional screws on the sides needs to be defined during the assembly (depends on screw support)
Note that when using screws for fastening, there can’t be anything flexible material between the lens and the PCB, for it my cause the lens to bend or crack

TAPE

Recommended to use LEDiL tape C14151_STRADA-2X2-TAPE
Tapes can be used to absorb some of the vibration

ADHESIVE

Use thin layer of adhesive on the area marked in green
In automated process it is easier to put glue straight to the PCB
