A light-emitting device including a substrate with a top surface and a bottom surface opposite to the top surface and a plurality of LED chips disposed on the top surface and configured to generate a top light visible above the top surface and a bottom light visible beneath the bottom surface, each LED chip comprising a plurality of light-emitting surfaces. The substrate has a thickness greater than 200 μm and comprises aluminum oxide, sapphire, glass, plastic, or rubber. The plurality of LED chips has an incident light with a wavelength of 420-470 nm. The top light and the bottom light have a color temperature difference of not greater than 1500K.

A waterproof socket-type halogen lamp for a livestock barn comprises a fixing body forming a hollow part, a side plate finishing the outside of the fixing body, a contact point, a wire, an annular insulator insulating the fixing body, a spring which is embedded in the hollow part and of which an outer side is supported by the side plate, an inner side supports the outer side of the annular insulator to provide restoration force while supporting one terminal of the tube halogen lamp through the contact point, and an inner waterproof packing which prevents moisture or dust from penetrating to the inner end of the fixing body and has a closed curve shape with a terminal passing groove through which a lamp terminal housing passes, and a tube halogen lamp in which lamp terminals at both ends are connected with the contact point by two socket parts.

A dome light assembly is provided for mounting to a headliner in a motor vehicle. That dome light assembly includes a mounting bracket having a flange engaging an upper face of the headliner and a receiver. Further, the dome light assembly includes a lamp housing including a fastener secured to the receiver and a light source held in the lamp housing. A related method is also provided.

An attachment device 10 for securing a lighting shade 20 to a lighting fixture 30, wherein the lighting shade 20 has an upper surface 22 for receiving thereon a plurality of magnet members 24, 26, and 28 that form the attachment device 10. The lighting fixture 30 has a connection housing 32 and an engaging surface 34 for engaging the attachment device 10 having magnet member 24, 26, and 28 on the upper surface 22 for retaining the removably connected lighting fixture 30 to the magnet members 24, 26, and 28 on the lighting shade.

An LED luminaire with reduced glare provides a polar arrayed light gradient on a diffuser lens and replicates the appearance of a filament or tube lamp. The luminaire includes a housing having an opening, a diffuser lens extending across the opening, and a plurality of LEDs positioned within the housing behind the diffuser lens. The plurality of LEDs are arranged to generate a composite light pattern having a polar arrayed light gradient across an aperture of the diffuser lens. The polar arrayed light gradient has a light intensity that decreases concentrically with increasing radius.

A device for installing a rear cover of an intelligent lamp cap, including a first feeding device for feeding a heat sink base and a second feeding device for feeding a LED lamp bead out to an outlet of the first feeding device and assembling the LED lamp bead with the heat sink base. A lead wire threading device is arranged on a side of a positioning-mounting mechanism, and is configured to guide a lead wire of the LED lamp bead to pass through a mounting hole of the heat sink base. A third feeding device is arranged on a side of the outlet of the first feeding device to mount a bottom cover on the heat sink base.

A diffuser for a hair dryer includes a diffusing case, a guide frame provided inside the diffusing case to guide a flow of gas introduced into the diffusing case, a light irradiator provided inside the diffusing case and in front of the guide frame to irradiate light toward a front side of the diffusing case, and a discharge cover provided at the front side of the diffusing case. The discharge cover includes a gas discharge hole to discharge the gas inside the diffusing case to outside. The discharge cover includes a plurality of massage protrusions to press a target located in front of the discharge cover.
