AI Technical Summary
Technical Problem
The light beams formed by existing LED lamps or halogen lamps and light guide components have a large divergence angle, making it difficult to form light spots in the far field, resulting in poor stage effects.
Method used
A combined laser light source is adopted, including a shell, a three-primary laser and a diameter mirror. The three-primary laser generates red, green and blue laser beams, and reflects them through the diameter mirror to overlap each laser beam to form beams of different colors.
Benefits of technology
Through the combined laser light source, the laser beam formed has a small divergence angle, which can form a clear light spot in the far field and improve the stage effect.

Abstract
The invention discloses a combined laser light source, and relates to the technical field of optics. The device specifically comprises a shell, a three-primary-color laser device and aperture mirrors, the three-primary-color laser device and the aperture mirrors are fixed in the shell, the three-primary-color laser device is used for generating a red laser beam, a green laser beam and a blue laser beam, and the aperture mirrors are arranged at the light-emitting ends of the red laser device, the green laser device and the blue laser device respectively. The laser beams are overlapped through reflection of the aperture mirror, the overlapped laser beams are used for forming light beams with different colors, the shell is provided with a light outlet, and the light beams reflected by the aperture mirror are transmitted out from the light outlet. The three-primary-color laser is adopted to form three laser beams, and laser beams of other colors can be formed through the three laser beams, so that the requirements of the stage lamp on the light beams of various colors can be met. Moreover, the scattering angle of the laser beam is small and not easy to diverge, clear light spots can be formed in a far field, and the device can be suitable for fields of various sizes.
