Note that the LG 1011 can be mounted into a housing feature 1061 of the combined LG and HM feature 1010.
[0034] Returning to FIG. 1 , the mounting plate 1 11 can use a same set of alignment features for alignment to the LED module 120 and to the HM feature 130 according to one or more embodiments. Further, same elements that are used in the LED module 120 for alignment to the mounting plate 11 1 can be used during an LED assembly for an LED alignment.
[0035] According to one or more embodiments, when the mounting plate 111 is created during an LG molding, elements for z-alignment can be shaped together with a front surface of the LG 1 10. In turn, the LG holder and referencing system 100 provides the technical effect and benefit enabling a very accurate control of a gap between the LED module 120 and the LG 1 10.
[0036] The mounting plate 11 1 has integrated alignment features in X, Y, Z. A common alignment mechanism in X, Y can be done by pins extracted from the LED module 120 going through holes in an alignment plate, and further into holes in the HM feature 130. Alternatively, pins extracted from the mounting plate 11 1 in both directions can be used. Further, pins from the HM feature 130 going through holes in the alignment plate and the LED module 120 can be used. The z reference can be generated by features molded into both sided of the mounting plate 1 11 . This enables a well-defined referencing when the mounting plate 1 11 is sandwiched between LED module 120 and the HM feature 130.
[0037] Further, additional elements can be integrated into the HM feature 130 to prevent unwanted light distribution, for example, a glare shield. FIG. 12 depicts an assembly module 1200 according to one or more embodiments. The assembly module 1200 can integrate a glare shield 1213.
[0038] Furthermore, a back reflector behind the LG 1 10 can be integrated into the LG holder and referencing system 100 to improve system efficiency and appearance. Generally, the LG holder and referencing system 100 cab be applied to automotive applications, for example, signaling.
[0039] FIG. 13 is a diagram of an example vehicle headlamp system 1300 that may incorporate one or more of the embodiments and examples described herein. The example vehicle headlamp system 1300 illustrated in FIG. 13 includes power lines 1302, a data bus 1304, an input filter and protection module 1306, a bus transceiver 1308, a sensor module 1310, an LED direct current to direct current (DC / DC) module 1312, a logic low-dropout (LDO) module 1314, a micro-controller 1316, and an active head lamp 1318. According to one or more embodiments, the example vehicle headlamp system 1300 can incorporate the one or more LG applications described herein. For example, the LG holder and referencing system 100 of FIG. 1 can be the active head lamp 1318 within the example vehicle headlamp system 1300.
[0040] The power lines 1302 may have inputs that receive power from a vehicle, and the data bus 1304 may have inputs / outputs over which data may be exchanged between the vehicle and the vehicle headlamp system 1300. For example, the vehicle headlamp system 1300 may receive instructions from other locations in the vehicle. Further, for example, the vehicle headlamp system1300 may receive instructions to turn on turn signaling or turn on headlamps. Furthermore, the vehicle headlamp system 1300 may send feedback to other locations in the vehicle if desired. The sensor module 1310 may be communicatively coupled to the data bus 1304 and may provide additional data to the vehicle headlamp system 1300 or other locations in the vehicle related to, for example, environmental conditions (e.g., time of day, rain, fog, or ambient light levels), vehicle state (e.g., parked, in-motion, speed of motion, or direction of motion), and presence / position of other objects (e.g., vehicles or pedestrians). A headlamp controller that is separate from any vehicle controller communicatively coupled to the vehicle data bus may also be included in the vehicle headlamp system 1300. In FIG. 13, the headlamp controller may be a micro-controller, for example, micro-controller ( c) 1316. The micro-controller 1316 may be communicatively coupled to the data bus 1304.
[0041] The input filter and protection module 1306 may be electrically coupled to the power lines 1302 and may, for example, support various filters to reduce conducted emissions and provide power immunity. Additionally, the input filter and protection module 1306 may provide electrostatic discharge (ESD) protection, load-dump protection, alternator field decay protection, and / or reverse polarity protection.
[0042] The LED DC / DC module 1312 may be coupled between the input filter and protection module 106 and the active headlamp 1318 to receive filtered power and provide a drive current to power LEDs in the LED array in the active headlamp 1318. The LED DC / DC module 1312 may have an input voltage between 13 and 18 volts with a nominal voltage of approximately 13.2 volts and an output voltage that may be slightly higher (e.g., 0.3 volts) than a maximum voltage for the LED array (e.g., as determined by factor or local calibration and operating condition adjustments due to load, temperature or other factors).
[0043] The logic LDO module 1314 may be coupled to the input filter and protection module 1306 to receive the filtered power. The logic LDO module 1314 may also be coupled to the micro-controller 1316 and the active headlamp 1318 to provide power to the micro-controller 1316 and / or electronics in the active headlamp 1318, for example, CMOS logic.
[0044] The bus transceiver 1308 may have, for example, a universal asynchronous receiver transmitter (UART) or serial peripheral interface (SPI) interface and may be coupled to the microcontroller 1316. The micro-controller 1316 may translate vehicle input based on, or including, data from the sensor module 1310. The translated vehicle input may include a video signal that is transferrable to an image buffer in the active headlamp 1318. In addition, the micro-controller 1316may load default image frames and test for open / short pixels during startup. In embodiments, an SPI interface may load an image buffer in CMOS. Image frames may be full frame, differential or partial frames. Other features of micro-controller 1316 may include control interface monitoring of CMOS status, including die temperature, as well as logic LDO output. In embodiments, LED DC / DC output may be dynamically controlled to minimize headroom. In addition to providing image frame data, other headlamp functions, for example, complementary use in conjunction with side marker or turn signal lights, and / or activation of daytime running lights, may also be controlled.

The LED lighting system 1406 may emit light beams 1416 (shown between arrows 1416a and 1416b in FIG. 14). In the embodiment shown in FIG. 14, a secondary optic 1410 is adjacent the LED lighting system 1408, and the light emitted from the LED lighting system 1408 passes through the secondary optic 1410. Similarly, a secondary optic 1412 is adjacent the LED lighting system 1406, and the light emitted from the LED lighting system 1406 passes through the secondary optic 1412. In alternative embodiments, no secondary optics 1410 / 812 are provided in the vehicle headlamp system.
[0047] Where included, the secondary optics 1410 / 812 may be or include one or more LGs. The one or more LGs may be edge lit or may have an interior opening that defines an interior edge of the LGs. LED lighting systems 1408 and 1406 may be inserted in the interior openings of the one or more LGs such that they inject light into the interior edge (interior opening LG) or exterior edge (edge lit LG) of the one or more LGs. In embodiments, the one or more LGs may shape the light emitted by the LED lighting systems 1408 and 1406 in a desired manner, for example, with a gradient, a chamfered distribution, a narrow distribution, a wide distribution, or an angular distribution.
[0048] The application platform 1402 may provide power and / or data to the LED lighting systems 1406 and / or 1408 via lines 1404, which may include one or more or a portion of the power lines 1302 and the data bus 1304 of FIG. 13. One or more sensors (which may be the sensors in the vehicle headlamp system 1400 or other additional sensors) may be internal or external to the housing of the application platform 1402. Alternatively, or in addition, as shown in the example vehicle headlamp system 1300 of FIG. 13, each LED lighting system 1408 and 1406 may include its own sensor module, connectivity and control module, power module, and / or LED array..
