Abstract: A connection assembly has a male connector, a first engaging ring securely mounted on the male connector, a female connector and a second engaging ring securely received in the female connector. The first engaging ring has first claws formed to abut a periphery defining the second annular groove formed on the female connector and the second engaging ring has second claws formed to abut a periphery defining the first annular groove formed on the male connector. Engagement between the male connector and the female connector is accomplished after the abutment between the first claws and the second annular groove and between the second claws and the first annular groove is finished.

Abstract: A BLU module has a plurality of BLUs assembled together. Each of the BLUs includes a light guide, a light source structure adjacent to the light guide, and a heat conduction member contacting the light source structure. The light guide has a light-emitting surface arranged on a top thereof and a bottom surface opposing the light-emitting surface, the light-emitting surface being larger than the bottom surface so that that light guide defines a first cavity formed therebetween. The light source structure is received in the first cavity. The light guide in two adjacent BLUs of the module defines a second cavity opposite the first cavity for receiving an adjacent heat conduction member of a prior adjacent light guide. The module is provided with a variable size with the BLUs assembled together to meet requirements.

Abstract: A white light LED assembly has at least two kinds of light-emitting units. The units can be a white light-emitting unit composed of red, green and blue LEDs, a white light-emitting unit composed of a blue and yellowish-green LEDs, a white light-emitting unit composed of a blue LED and yellow phosphor, or a white light-emitting units composed of UV LED and red, green and blue phosphors. The white light LED assembly according to the present invention has satisfactory efficiency and color rendering property as well as flexible phosphor usage.

Abstract: An illumination apparatus has a frame with a plurality of fins, at least one thermally conductive sheet and at least one illumination module. The illumination modules are positioned on the frame, and the thermally conductive sheets are positioned between the frame and the illumination modules. Thus, the illumination modules generate light beams and heat, which is carried away by the frame with a plurality of fins.

Abstract: A light emitting diode light source has a printed circuit board with a plurality of side faces, a plurality of RGB LED units arranged on one side face of the printed circuit board and each having a red LED, a green LED and a blue LED, and at least one control unit connected to each LED in the RGB LED units and controlling a driving current to the LED. Each of the RGB LED units emits a white light with stable color temperature. The control unit has a memory for storing a driving current data for each LED.

Abstract: A self-locking quick release coupler includes a handle and a lever. The first distal end of the handle is adapted to be secured to a side face of the groove adapter. The handle has a head formed on the first distal end thereof. The head is extendable into a side face of the groove adapter so as to secure a tube inserted into the groove adapter. The lever partially extends through the handle to be pivotably received in the handle. The lever has a hook formed on a first distal end of the lever to adapt to hook a pin of the groove adapter and a press formed on a second distal end of the lever. The pivotable movement of the lever allows the hook of the lever to selectively hook the pin so as to secure the handle relative to the groove adapter.

Abstract: A self-locking quick-disconnect coupling device includes a female coupler including a stop formed thereon and an opening defined therethrough. A male adaptor through which a recess is defined is insertable into the female coupler. A cam handle includes a handle portion and a cam portion rotatably mounted on the coupler between a releasing and an engaging position so that the cam portion is moved through the hole into the recess. A hooking element is pivotably linked to the handle portion. The hooking element includes a barb projecting therefrom and including an inclined surface. A locking control element including first and second distal ends is pivotably linked to the handle portion. The inclined surface will slide on the stop when the cam portion is pivoted from the releasing position to the engaging position thus allowing the barb to snap into engagement with the stop when the cam handle is in the engaging position.

Abstract: A bucket valve with a removable handle includes a tubular valve body, a piston disposed with the valve body and a crank arm integrally formed of a central sleeve and two spaced fingers. The fingers are pivotally retained to the piston. A drive shaft is drivingly disposed in and extends from the central sleeve of the crank arm to project through and beyond the valve body to connect by a distal tip thereof to a handle via an axle sleeve. An `L`-shaped latch is resiliently retained in the axle sleeve whereby the combined axle sleeve and handle are removably retained to the drive shaft. The handle has a forked tip forming an outer upper face, a central fork and an outer lower face against each of which a knob can abut in a first, second and third position respectively.

Abstract: A device for locking a lever for pivoting a valve contained in a valve housing. A recess is formed in the valve housing. An annular groove is formed in the recess. A spring is sited in the recess. A latch has a relatively large middle section connecting an upper section with a lower section. The latch is sited in the recess so that the lower section thereof is inserted in the spring and that the middle portion thereof is sited on the spring. A C-ring engages in the groove so that the latch is trapped in the recess. A hole is formed in the lever. The hole has an upper section and a relatively large lower section. A wedge surface is formed on the underside of the lever. A button has a body connecting with a relatively large head and a groove formed about the body. The body of the button is inserted through the upper section of the hole. A C-clip engages in the groove formed about the body so that the button is trapped in the hole.
