A lighting unit includes a first light source to emit first light; and a diffusive body including a first incidence surface that allows the first light to enter, a diffusive part that includes nanoparticles, guides the entered first light and makes the first light be scattered by the nanoparticles into first scattered light, and an emission surface that emits the first scattered light, wherein the first incidence surface is formed on a first edge part of the diffusive body, the first scattered light is emitted from a first region of the emission surface, and a correlated color temperature of the first scattered light is higher than a correlated color temperature of the first light.

The present disclosure provides a lighting device for use with inflatable products, such as balloons. Specifically, the lighting device may be configured to utilize external audio to produce a pattern of light corresponding with the external audio. The lighting device is able to couple to a balloon to light up the interior of the balloon without the significant loss of gas or other inflating fluid from the balloon.

A baby monitor assembly includes an emitter unit and a receiver unit, wherein the emitter unit includes means for sound detection, such as a microphone, means for communication with the receiver unit, a generally flat housing, having a peripheral slit, and a source of light. The receiver unit includes means for communication with the emitter unit, and signalizing means. The emitter unit is suitable and configured for placing under a crib, and is capable of detecting sounds and sending information to the receiver unit upon detection of predetermined type of noise. The receiver unit is configured for receiving information from the emitter unit and notifying the parent, such as using light, sound or vibration signals. A slit in the housing allows for emitting a light beam selectively essentially parallel to the floor, so that it neither shines directly nor reflects into the eyes of the baby and the user.

A plant cultivation light source includes a substrate and a first group of light sources. The first group of light sources includes a plurality of light sources disposed on the substrate, and a light source including a light emitting structure including a first semiconductor layer, an active layer, and a second semiconductor layer. The plurality of light sources operates to emit lights having different wavelength bands and includes a first light source that emits first light having an area of at least about 55% compared with an area of a normalized solar spectrum, a second light source that emits second light having a wavelength for cryptochrome, and a third light source that emits third light having a wavelength for phytochrome.

A folded light engine comprising an array of LEDs mounted on a strip substrate, wherein the strip substrate comprises a central portion provided with a first set of through-holes, a first peripheral portion provided with an electrically conducting track connecting a first group of LEDs and a second set of through holes, and a second peripheral portion provided with an electrically conducting track connecting a second group of LEDs. The first peripheral portion is folded over the central portion, so that the LEDs thereon coincide with through-holes in the central portion, and the second peripheral portion is folded over the first peripheral portion, so that each LEDs thereon coincide with a combined through-hole formed by through-holes in the central portion and in the first peripheral portion. An elongated light engine can be cost efficiently manufactured in a relatively simple processes, including single-sided circuit patterning and LED mounting.

Speaker systems are provided, particularly for mounting in off-road vehicles, ATVs, UTVs, watercraft and motorcycles. The speaker systems may include a linear array of speakers and a housing encasing a backside thereof. In some cases, the speaker systems include a pipe-mounting clamp coupled to the housing for mounting the speaker system to a surface. In addition or alternatively, the speaker systems may include mounting brackets arranged along opposing lateral sides of the housing for mounting the speaker system to a surface. In any case, the speaker systems may include a power cord extending from one of the opposing lateral sides of the housing in some embodiments.

An illumination device includes two illumination sections. The first illumination section includes a plurality of illumination elements that are each configured to emit light in a light spectrum, wherein the light spectrum is variable. The second illumination section includes one or several illumination elements that are each configured to emit light in a fixed light spectrum, wherein the fixed light spectrum is white.

A color changing television antenna with LED includes a casing, an antenna radiator in the casing, a coaxial cable situated at a rear end of the casing and connected to the antenna radiator. The casing contains an LED lamp, and a transparent display panel extending to the outside from the display panel. The part of the display panel inside the casing has a receiving slot for installing the LED lamp and allowing the LED lamp to project light onto a sidewall of the receiving slot. The display panel transmits the projected light by total reflection. A reflector is installed on a surface of the display panel for reflecting the light transmitted inside the display panel and forming a predetermined pattern. This television antenna can display a specific pattern and improve the display effect based on the principle of total reflection of the transparent display panel.
