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.

Abstract: A probe for a non-excavation guide can include an outer casing and a transmitting antenna. The transmitting antenna can be disposed in the outer casing, with the transmitting antenna including a magnetic core and a coil. The magnetic core can include a plurality of magnetic core segments. The magnetic core segments can be annular in shape and thereby define a hollow segment interior. The magnetic core segments can be sequentially arranged within the outer casing, with the coil located around an outside of the plurality of magnetic core segments. The probe assembly can facilitate the manufacture of the magnetic cores, reduce the disposition of insulating members, facilitate the assembly of the transmitting antenna, and/or reduce production costs.
