A LED light device includes a light-emitting diode assembly including a light body and one or more LEDs supporting thereat, and a heat dissipating arrangement including a plurality of heat dissipating fins radially and outwardly extended from the light body to define a heat dissipating channel between every two of the heat dissipating fins, and an air guiding member coupled at the front side of the light body. Each of the heat dissipating channels has a front opening extended at the front side of the light body and an elongated side opening for dissipating heat generated from the LED assembly. An air guiding member has a plurality of guiding inlets aligning with the front openings of the heat dissipating channels respectively for guiding air flowing to the heat dissipating channels so as to effectively dissipating the heat from the LED assembly through the heat dissipating fins.

The invention discloses a nanometer spherical porous weak light photocatalyst for degrading nitrogen oxide, and a preparation method and an application thereof. The photocatalyst comprises 0.2-35wt% of a titanium source, 64-99wt% of an alcohol solvent, 0.005-0.01wt% of a hydrolysis inhibitor, 0.005-0.01wt% of metal ion-containing deionized water, 5-50wt% of hydroxy group-containing mediate strong acid, and 1-5wt% of inorganic dispersant-containing deionized water, and the hydroxy group-containing mediate strong acid contains SiO2 crystal seeds; and the photocatalyst is a transparent sol liquid of nanoparticles, the particle size of the transparent sol liquid is 10-30nm, the surface of the photocatalyst is spherical porous distribution, and the specific surface area of the photocatalyst is large, and is above 300m<2> / g averagely. The photocatalyst has the advantages of mild production preparation conditions, small production safety risk, easy realization of batch production, weak light catalytic purification and high stability, and solves the problems of strict preparation conditions, low sunshine utilization rate, low air purifying and degrading efficiency, large base material apparent influence, construction inconvenience and the like of present mature photocatalyst products.

A lamp includes a rotary adjustment mechanism, an inclination adjustment mechanism and a light source. The light source is rotatable along a first direction in a first plane by the rotary adjustment mechanism and / or rotatable relative along a second direction in a second plane by the inclination adjustment mechanism, wherein the second plane is different from the first plane.

A screw according to the present disclosure includes a head, a shank, a thread, a plurality of first ribs and at least one second rib. The thread is formed on the shank. The head is formed at one end of the shank and is configured to receive a fastening tool. The head is of tapered shape and has tapered side-surfaces, which include a first side surface and a second side surface. The second side surface is located between the first side surface and the shank. The first ribs are positioned on the first side surface. The second rib is positioned on the second side surface.

The present invention provides a mouse device, including a housing, a telescopic portion, and a motor. The housing includes a base, an upper cover covering the base, and a through hole located between the upper cover and the base. The telescopic portion may move outward the housing through the through hole. The motor is disposed within the housing, and is configured to provide a power to the telescopic portion, so as to adjust a volume of the telescopic portion exposed outside the housing to support a hand portion of a user.
