  • Patent number: 11802673
    Abstract: An intelligent dimming RGB LED spotlight comprises an outer shell, a lamp base and a lampshade. A drive board connects to the lamp base and a light source board. The light source board is provided with dense ordinary-color-temperature lamp beads and RGB color-changing lamp beads, and is connected above to the lampshade corresponding to the RGB color-changing lamp beads. A method for achieving the intelligent dimming RGB LED spotlight includes the lampshade scattering the light emitted by the RGB color-changing lamp beads, so as to reduce the light intensity and make the light-emitting area larger and the emitted light more uniform, while it does not block the light emitted by the ordinary-color-temperature lamp beads, which makes the generated light spot have balanced illumination and a uniform and high-purity color in the color-changing process of a variety of colors, able to achieve the effect of AA level of GB illumination.
