摘要： A dual phosphor wheel projection system is provided. A first dichroic mirror directs blue light from a first blue laser to a second dichroic mirror which directs the blue light to at least one integrator. The first dichroic mirror directs blue light from a second blue laser to a first phosphor/ phosphor wheel, which converts the blue light to longer wavelengths that includes red light. The second dichroic mirror directs the red light to the integrator and transmit others of the longer wavelengths. The integrator combines the red light with red light from a red laser. A third dichroic mirror directs the red light from the red laser to the integrator and directs blue light from a third blue laser to a second phosphor/phosphor wheel, which converts the blue light to respective longer wavelengths that includes green light. The third dichroic mirror transmits the green light to the integrator.

摘要： A system and method for controlling the energy of light pulses for use with a projection optics system is provided. The system includes a light source 216 configured to emit light pulses, a transmission element configured to transmit a first part 212a and a second part 212b of an active light pulse, the first part being transmitted to the projection optics system, and a feedback system including a detector 242 configured to receive the second part of the active light pulse and determine a total measure of energy of the active light pulse, and a control unit 232 configured to receive the total measure of energy and in response control an amplitude of a subsequent light pulse. In some implementations, the control unit may additionally set a threshold value for communication to a comparator to compare against the total measure of energy and in response control the width of the active light pulse.

摘要： A light source system and a projection display device comprising the light source system. The light source system comprises at least three light sources (10, 20, 30) used for generating at least two wide-spectrum light beams, a light splitting and combining device (40), and at least two spatial light modulators, i.e. a first spatial light modulator (50) and a second spatial light modulator (60), wherein a first wide-spectrum light beam and a second wide-spectrum light beam generate light with two colours and at least four primary wavelengths after being split by the light splitting and combining device (40), thereby expanding the colour gamut range and improving the quality of image display. In addition, using two spatial light modulators to modulate light simultaneously takes account of the costs of products while guaranteeing the image display quality.

摘要： A light source comprising an excitation light source (110) for providing excitation light, and an optical wavelength conversion member disposed at a distance from the excitation light source. The optical wavelength conversion member comprises an optical wavelength conversion material (150) for converting the excitation light into stimulated light. The light source also comprises an optical-guiding member that allows the excitation light to be incident on the optical wavelength conversion material, and an optical-collecting member (130A) for collecting stimulated light originating from the optical wavelength conversion material. To separate the paths of the stimulated light and the excitation light, the etendue of the optical-guiding member is less than or equal to ¼ of the etendue of the optical-collecting member. This allows the optical-guiding member to draw in the excitation light while preventing the excessive escape of the stimulated light through the optical-guiding member. The advantages of the light source are that it can separate the paths of the excitation light and the stimulated light, the light path is simple, and the optical members are easy to manufacture.

摘要： A light-emitting device and a projection system, comprising: a laser array light source (210, 310, 410) which comprises a non-light-emitting region (212, 312) and a light-emitting region (211, 311) consisting of a plurality of laser elements; a reflective light-condensing system (230, 330, 430) which comprises a light-condensing region (331a, 431a) and a non-light-condensing region (331b, 431b), wherein the light-condensing region (331a, 431a) is used for focusing and reflecting emergent light of the laser array light source (210, 310, 410); and a light-collecting system (240, 340, 440) used for collecting and emitting the emergent light from the reflective light-condensing system (230, 330, 430). The light-collecting system (240, 340, 440), the non-light-emitting region (212, 312) and the non-light-condensing region (331b, 431b) are located in the same straight line parallel to a light axis of the emergent light of the laser array light source (210, 310, 410), and the light-collecting system (240, 340, 440) passes through the non-light-emitting region (212, 312) and/or the non-light-condensing region (331b, 431b). The light-emitting device and the projection system have small volumes and can emit high-brightness and uniform faculae.
