Apparatus of projector headlights
This invention is a projector headlight that, while offering dual beam patterns, boasts a 100% utilization of the light emitted from a light source by one of the following methods: (1) employing a reflective cutoff shield means to reflect the incoming light from said light source back to the reflector to enhance the illumination in low-beam pattern, (2) using reversible cutoff shield means to reflect the incoming light from said light source back to the reflector to enhance the illumination in low-beam pattern with no moving part involved, (3) utilizing a selective light-filter cutoff means to selectively reflect the incoming light from said light source back to the reflector to enhance the illumination in low-beam pattern without making use of any moving part, (4) using a low-beam light-emitting subassembly and a high-beam light-emitting subassembly that are separated by partition means to achieve dual beam patterns with no moving part, or (5) adopting a low-beam light-emitting subassembly in low-beam pattern and a high-beam light-emitting subassembly in high-beam pattern without any moving part.
In-vehicle headlight and light projection method
Reliability of an in-vehicle headlight is improved by changing a light distribution pattern without using any mechanical configuration. The in-vehicle headlight includes a laser light source, a spatial light modulator, a spatial-light-modulator controller, and a projection lens. The laser light source emits a laser light beam. The spatial light modulator modulates a phase distribution of the laser light beam emitted by the laser light source. The spatial-light-modulator controller is provided in a headlight controller, and controls the spatial light modulator. The spatial-light-modulator controller controls the spatial light modulator so as to modulate the phase distribution of the laser light beam, and changes the light distribution pattern projected from the projection lens.

Stainless steel LED power switch
An encapsulated LED switch that incorporates a MOSFET power drivers, high current transistors, or other suitable power drivers in a PCB that attaches to the LED switch such that a low power LED switch controls the output of a high-power driver. The selected power driver PCB can be adapted to different load requirements by making simple changes. The PCB's can be interchanged to provide for a predetermined output power required for a particular application. In addition, the wire gauge size of the wires attached to the MOSFET power driver PCB can also be varied to match intended load requirements. For applications in which the LED switch is used in hostile environments, such as marine applications, the LED switch and its associated power driver PCB are encapsulated to protect the circuitry from environmental factors such as high humidity, salt water, etc.
