  • Patent number: 11509873
    Abstract: A light source generating device, a projection apparatus and a light source generation method are provided. The light source generating device includes a first light source, an auxiliary light source, a control device, a driver and a current command generator. The first light source generates a first light beam. The auxiliary light source generates an auxiliary light beam corresponding to the first light beam. The control device generates a first driving signal to drive the first light source. The driver generates an auxiliary driving signal to drive the auxiliary light source according to the gate control signal and a current command. The current command generator receives an indication signal, and generates the current command according to the indication signal, wherein the indication signal corresponds to a driving current of the first light source. The invention has an effect of enhancing brightness/chrominance.

  • Patent number: 10948813
    Abstract: A projection system, a beam generating apparatus, and a beam generating method are provided. The beam generating apparatus includes a plurality of light emitting devices, a plurality of drivers, and a first auxiliary driver. The light emitting devices respectively generate a plurality of color lights with different wavelengths. The drivers respectively drive the light emitting devices according to a plurality of control signals. The first auxiliary driver drives a first light emitting device according to a first auxiliary control signal, and adjusts brightness of the first light emitting device according to a first regulating signal. When the first auxiliary control signal is enabled, the control signal corresponding the first light emitting device is disabled.

  • Patent number: 10133172
    Abstract: A lens module includes a lens, a first gravity sensor and a processor. The lens includes an optical axis and an adjustment assembly. The adjustment assembly rotates around the optical axis. The first gravity sensor is disposed on the adjustment assembly. The adjustment assembly drives the first gravity sensor to rotate. The first gravity sensor is configured to perform detection at different time points. The first gravity sensor generates a first output at a first time point and a second output at a second time point. The processor calculates first and second angles of the first gravity sensor relative to a water level according to the first and second outputs respectively. The processor controls a focus adjustment of the lens according to the first angle and the second angle. A projector employing the aforementioned lens module is also provided.
