  • Patent number: 8101434
    Abstract: A method for LED-module assembly comprising the steps of providing a base portion with a base inner surface and a cover with a cover inner surface which together define a module interior, the cover having at least one opening therethrough; putting a sealing member into the module interior; positioning an LED lens into the cover opening; aligning an LED emitter and the LED lens within the module interior; sealing the module interior by securing the base portion with respect to the cover. The LED emitter is powered for imaging of the LED module to test light-output characteristics. A specific type of the LED lens is selected and its type and orientation are verified. The step of vacuum testing checks for water-air/tightness of the sealing of LED-module interior. A central database provides assembly and testing parameters to automated tool(s) performing each particular step.
