SPECIFICATION FOR TESTING AUTOMOTIVE LED MODULES

Abstract

<div class="section abstract"> <div class="htmlview paragraph">This specification is a general level subsystem light source specification that establishes test requirements of light emitting diode (LED) components and modules for use in automotive lighting systems.</div> <div class="htmlview paragraph">The completed test data from this test specification is intended to be provided to the OEM by the Tier 1 lamp set maker as part of the lamp assembly PPAP. Re-testing shall be required if any portion of the approved LED module experiences a design, manufacturing, or component change.</div> <div class="htmlview paragraph">This document shall be applied to systems that meet the requirements for design, performance, and validation established by government standards.</div> <div class="htmlview paragraph">The LED module is defined as the LED devices and any electronics required to properly energize the LEDs using a vehicle electrical power system along with any associated electrical wiring, connectors, and thermal management system. Samples shall be tested as a subsystem and considered one test sample for the entire test sequence. A failure of any component in the test sample shall constitute a failure of the entire sample.</div> <div class="htmlview paragraph">NOTE: If other manufacturers’ components are intended to be approved for use in the LED modules, then those possible combinations of components shall be considered a new LED module and shall also be tested.</div> <div class="htmlview paragraph">Additional testing may be required by individual OEMs to meet specific EMC, quality, reliability, and durability objectives.</div> <div class="htmlview paragraph">The following tests are to be performed under the following conditions:</div> <ul class="list disc"> <li class="list-item"> <div class="htmlview paragraph">New sample.</div></li> <li class="list-item"> <div class="htmlview paragraph">Design or process change made to an existing module.</div></li> <li class="list-item"> <div class="htmlview paragraph">Completion of one calendar year as noted in the annual tests table shown in <span class="xref">Appendix E</span>. <i>(Note: Production process control data, collected at a shorter interval per an approved control plan, may be substituted if approved by customer’s responsible engineer and purchasing representative.)</i></div></li></ul></div>
