A Christmas tree stand connecting structure and an LED decorative lamp are disclosed. The Christmas tree stand connecting structure includes a fixed disc and an LED decorative lamp, wherein a side wall of the fixed disc is movably connected with a supporting frame. A top of the fixed disc is equipped with a connecting mechanism, wherein an angle adjusting assembly is arranged in the connecting mechanism. The connecting mechanism includes a connecting part, a positioning part, a connecting end, a connecting line, and a connecting port. The connecting part is assembled through the positioning part on a bottom of the connecting part and the positioning slot in a top. In a mounting process, a blocking part inside a matching slot is jacked to two sides through a semicircular structure on the top for a clamping part to clamp and fix a side wall of the blocking part.

A guitar holder with a built-in guitar amplifier for enabling convenient guitar practice and/or play with a compact, space-saving footprint. The guitar holder may comprise any of a variety of guitar holders, including but not limited to a guitar stand and/or a guitar wall hanger.

A lighting fixture with transparent antennas and heat spreaders, including: conductive portions made with conductive materials, and non-conductive portions made with non-conductive materials; one or more free spaces, enclosed between said conductive portions and the non-conductive portions; one or more anchor points, positioned inside said free spaces, for fixing one or more mechanical adapters; one or more electricity supply interfaces, positioned inside said free spaces, for electrically powering the lighting fixture with an available power supply; a removable and optically transparent screen, including non-conductive elements, made with non-conductive materials, and conductive elements, made with conductive materials, the screen being equipped with optically transparent antennas, metallized through holes, optically transparent transmission lines and optically transparent heat spreaders; a metallic outer frame protecting the optically transparent screen in which are positioned radio frequency connectors and connected to the optically transparent screen and to the optically transparent transmission lines.

A portable slit lamp device which can be coupled to an image capture device such as a smartphone.

A power tool includes a housing, a motor, a power output member, a transmission assembly, and a light source device. The power output member extends substantially along an axis and is connected to an operating accessory, and the operating accessory is provided with a working portion. The light source device includes a light guide plate, a light-emitting element, and a circuit board. The light guide plate is formed with a light exit surface for emitting light and a first light incident surface and a second light incident surface for guiding light into the light guide plate. The circuit board is used for installing the light-emitting element. A maximum distance L between the first light incident surface and the second light incident surface along a left-and-right direction is greater than or equal to 0 mm and less than or equal to 7 mm.

A light speaker structure with a ring handle includes a speaker body, a speaker enclosure, a lighting mechanism and an auxiliary mechanism. The speaker body is mounted within the speaker enclosure, and the auxiliary mechanism is mounted on the speaker enclosure. The lighting mechanism includes a lampshade, a light strip, and LED beads. The light strip is mounted within the lampshade. The LED beads are fixedly connected to the light strip and electrically connected to the speaker body. The light strip is disposed in a laterally inverted C-shape around the speaker enclosure. The lampshade covers the light strip, so that the light strip is held between the lampshade and the speaker enclosure. The light strip and the lampshade are so shaped that they can be arranged around the speaker enclosure, thereby achieving a better lighting effect, providing a larger lighting area and producing a stereoscopic effect.

Systems, methods, and apparatuses for emitting light from a header reel are disclosed. More particularly, systems, methods, and apparatuses for emitting light from one or more apertures formed in a reel finger are disclosed. The reel fingers included on a reel may include a cavity through which light is transmitted. The emitted light provides for illumination and operator visualization during, for example, agricultural operations performed at night or during low ambient light conditions.

Systems, methods, and apparatuses for emitting light from a header reel are disclosed. More particularly, systems, methods, and apparatuses for selectively emitting light from different portions of a reel header are disclosed. In some implementations, light is selectively emitted from different parts of a reel header based on a position of the reel header. For example, light may be emitted based on a position of the portion of the reel header as the reel header is rotated. The emitted light provides for illumination and operator visualization during, for example, agricultural operations performed at night or during low ambient light conditions.
