Abstract

The invention discloses a laser projection method and a laser projector and belongs to the projection field. The method comprises the following steps of acquiring a target light source brightness value of the laser projector, wherein the laser projector includes a light source module; the light source module includes at least one laser; and the light source module can emit at least one color of light; according to the target light source brightness value, inquiring a corresponding relation of a preset brightness value and a driving current value and determining a target driving current value corresponding to the target light source brightness value, wherein the corresponding relation is used for recording that the light source brightness values of the laser projector are n brightness values respectively and recording the driving current value of the corresponding laser in a period of generating each color of light when a color temperature value of synthesis light synthesized by the at least one color of light is a target color temperature value; and adjusting the driving current value corresponding to the each color of light to the target driving current value. In the prior art, color temperature consistency is low. By using the method and the projector of the invention, the above problem is solved. And the method and the projector of the invention are used for laser projection.

Description

technical field [0001] The invention relates to the field of projection, in particular to a laser projection method and a laser projector. Background technique [0002] A laser projector is a projector that uses a laser beam to transmit a projected image, mainly including a light source module, an optomechanical module and other components. [0003] The light source module of a laser projector usually includes a laser and a fluorescent wheel as a wavelength conversion device. The laser can be a single-color laser or a two-color laser, which emits one or two colors of laser light. The fluorescent powder is provided on the fluorescent wheel, which can be excited to the corresponding color of fluorescence, which is used to match the color of the laser emitted by the laser. Together, they form three primary colors, which are used as projection light sources to provide illumination to the optomechanical part. [0004] The brightness of the projection light source determines the...
