Abstract: The present invention discloses a solar water cooler, which includes a water tank, a condensing panel, and an auxiliary refrigerating devices, wherein the water tank has an insulating panel transversely embedded into the water tank for separating the water tank into an upper cooling chamber and a lower chilling chamber, a pair of inner conduits for respectively communicating the cooling chamber to the chilling chamber, each of the cooling chamber and the chilling chamber has a water inlet port and a water outlet port, a plurality of conduits for respectively communicating the water tank to the condensing panel and the auxiliary refrigerating devices, wherein the auxiliary refrigerating device electrically powered by solar cells and by thermocells.

Abstract: A portable radial projection light source arrangement includes a shelter housing and an illumination unit. The shelter housing includes a protection base having a light source cavity therein, and a supporting frame mounted on the protection base. The illumination unit includes a power source supported in the protection base, a light source disposed in the light source cavity and electrically connected to the power source, and a reflecting member supported at a position coaxially above the light source wherein the reflecting member has a light reflecting surface radially projected from the light source in such a manner that when the light source emits light, the light is radially reflected by the light reflecting surface of the reflecting member to outside.

Abstract: A lighting fixture includes a light housing having two housing portions transversely extended at an adjacent angle less than 180 degrees to define a front angled opening, and a reflector having two reflecting portions received in the two housing portions of the light housing respectively wherein each of the reflecting portions of the reflector has a reflecting surface formed at an inner wall of the respective housing portion of the light housing. A light source arrangement includes two light sources, which are adapted for electrically connecting to a power source, supported within the two housing portions of the light housing respectively wherein the two light sources are arranged for producing lights to reflect on the two reflecting surfaces of the reflector respectively so as to project to outside through the front angled opening of the light housing with a wide projecting angle.

Abstract: A light tube for a cold electrode fluorescent lamp includes a light tube body, a first electrode and a second electrode disposed in the light tube body and an activated gas absorber. The light tube body contains inert gas, mercury substance and a layer of phosphor coating on its inner surface. The second electrode is adapted for electrically connecting to the an electric terminal for emitting electrons to excite the mercury substance for conducting the electrons to the first electrode as an electric loop, wherein the excited mercury substance emits ultra violet rays causing the phosphor coating to generate visible light. The activated gas absorber is gas absorber made of zirconium-vanadium-iron alloy which can be activated at an activation temperature substantially lower than 900 degrees Celsius, preferably 390 degrees Celsius, to provide stronger oxygenic gas absorption ability while reducing the manufacturing steps and cost.

Abstract: A power latch assembly which includes a supporting frame adapted for mounting on a main housing, wherein the supporting frame has a locking slot and defines first and second slider ends thereof; a motor assembly including a power motor supported by the supporting base and adapted for being powered by the main housing, and a driving arm driven by the power motor in a linear movable manner; and a locking latch, defining a first guiding edge and a second guiding edge, having an inner coupling end coupling with the driving arm and an opposed latching end extended outwardly through the locking slot, wherein the driving arm drives the locking latch between a locking position and an unlocked position.
