摘要： The invention describes a laser-based light source (100) which is adapted to use the angular dependence of the reflection of polarized laser light (10) at a surface of a conversion material to control especially the color point of light emitted by means of the laser-based light source (100). The reflected laser light is within a first wavelength range and the converted light is in a second wavelength range different from the first wavelength range such that the color point of the light emitted by means of the laser-based light source (100) in a defined solid angle depends on the ratio between reflected and converted light. The invention further describes a corresponding method of light emission control, a vehicle headlight (200) comprising such a laser-based light source (100) and a lighting system comprising such vehicle headlights (200).

摘要： Disclosed is a dimming device comprising a light source, a support, a diffuser for light diffusion, and blades for light shielding. The support being provided with a light path corresponding to the light source, and notches being provided on the blades. The blades and the diffuser are movably disposed on the support with the blades and the diffuser actuated by independent actuators. The notches of the blades move into and out of the light path with the movements of the blades into and out of the light path, and the diffuser covers a portion of notches that is within the light path when moving into and out of the light path. The blades and the diffuser are independently actuated in the present invention such that the movement of the diffuser within or outside the light path is not limited to that of the blades. Therefore, the diffuser can be precisely controlled to move into a specific position within the light path with an optimal trajectory and at an optimal time point to achieve light diffusion. The diffuser is integrally formed and has no slots, ensuring the diffusion of all the light passing through the portion of the notches that is within the range of the light path.

摘要： A lighting device (100) and a projection device, comprising a light source for generating a blue excitation light (110), a base board (130), and a wavelength conversion material layer (140) covered on the base board (130). The wavelength conversion material layer (140) absorbs a part of the blue excitation light and emits an excited light. The color coordinate of the excited light is within the pre-configured color area, so that a mixed light combined by the excited light and the remaining blue excitation light not absorbed by the wavelength conversion material layer (140) exits the wavelength conversion material layer (140). The color coordinate of the mixed light is closer to the pre-set blue light color coordinate than the color coordinate of the blue excitation light.
