A lighting fixture apparatus includes a frame portion, a louver portion and a diffuser lens. The louver portion includes a baffle system for passing unobstructed at least a portion of the light impinging thereon. The diffuser lens includes a surface for diffusing light rays. At least one directional lighting apparatus comprised of LED strips is attached to and supported by the frame portion. The LED strips are disposed between the louver portion and the diffuser portion. The LED assembly includes a rigid strip having a first end and a second end opposite the first end portion, and a first surface and a second surface opposite the second surface. A first rotary support member and a second rotary support member are connected to the strip portion at respective first and second ends. A plurality of electrical lighting elements are mounted on the first surface and are configured in at least one electrical circuit.

A corrugated fin or turbulizer for a heat exchanger comprises a series of corrugations with parallel side walls. The side walls are provided with a series of parallel slits between which one-sided or two-sided louvers are defined. Each of the louvers has first and second edges extending along an adjacent pair of slits, and at least one bend located between the edges, thereby causing at least one of the edges of the louver to project outwardly of the plane of the side wall, and providing the side wall with improved crush resistance. The corrugations may preferably be rectangular or trapezoidal in form, having generally flat top and bottom surfaces defined by two closely-spaced bends. The top and bottom surfaces may preferably be provided with protrusions, at least some of which extend close to the bends. This assists in creating localized areas of weakness along which the bends can be formed cleanly.

This invention relates to a luminaire (106), which has a housing (103) with an opening (111) at a light output side, a reflector (105) mounted in the housing, and facing the light output side, a louver (107) mounted at the opening of the housing, and LEDs (109) mounted in the louver, such that the emitted LED light exits the luminaire only after reflection against the reflector, thereby providing indirect light output.

A louver panel for an electronic sign incorporating multiple spaced primary and secondary louvers extending outwardly from a configured substantially planar panel to provide direct shading of the structure adjacent to an LED, to the structure of the louver panel including the louvers and the panel, and to provide shading for all or part of an LED. Spacings of the louvers provide for regions of shade which improve contrast and which in transition between panels camouflage horizontal seams.

A universal mobile telephone headpiece holder includes a U-shaped receiver member, configured to hold an earpiece, and a generally linear support member that is capable to engage a curved member on a telephone headpiece not having an earpiece to support the headpiece within convenient reach of an operator of an automobile vehicle while the headpiece is not in use. The receiver member can be configured for mounting in different attachment members to be detachable therefrom. The attachment member can be in the form of a clip engagable with an air conditioning vent grille louver or an adhesive member that is simply stuck on a flush surface of the dashboard. Through the universal telephone headpiece holder, the headpiece can be supported at an elevated location to be accessed when the phone rings without searching for the headpiece.

A garbage can has two shutters, which can be made to pivot between a closed position by means of a tension spring and an opened position by means of depressing a pedal; the pedal is connected to a connecting rod up and down movable together with an actuating plate for the shutters; the connecting rod is further connected to a buffer mechanism consisting of a fixed rod part, and main body, which is movable relative to the rod part together with the connecting rod, so that the main body will move up relative to the rod part at such a speed as to counteract the tension spring, and slow down the movement of the shutters from the opened position to the closed position after the pedal is released from the depressed position, preventing the shutters from hitting the containing body too hard.

A method of making a micro-louver structure includes coating a curable layer on a surface and imprinting a pattern of micro-channels in the curable layer. The micro-channels have a greater depth than width and are spaced apart by a separation distance greater than the width. The curable layer is at least partially cured to form a cured layer. A light-absorbing material is coated over the cured layer and in the micro-channels and at least a portion of the light-absorbing material removed from the surface of the cured layer leaving at least a portion of the light-absorbing material in the micro-channels. The light-absorbing material is cured to form a light-absorbing structure in each micro-channel.

An airflow regulating device includes a first airflow regulator configured to replace a tractor truck's grille, means for adjusting the first airflow regulator between open and closed configurations, a second airflow regulator positioned inside a housing configured to attach atop the truck's cab, means for adjusting the second airflow regulator between open and closed configurations, and means for actuating each adjustment means. The second airflow regulator may embody either a multiple-louver or a nested-panel formation, and a proximity sensor is included in the means to actuate the adjustment means of the second airflow regulator. The first and second actuation means determine whether the first and second airflow regulators should be in the open or closed configurations and actuate the first and second adjustment means accordingly. The first and second adjustment means then adjust the first and second airflow regulators to the appropriate configurations, improving the truck's gas mileage.

The invention provides a vane-type mist eliminator device having formed or corrugated sheets, flat sheets, and integral louvers. The corrugated sheets and flat sheets are layered such that the arrangement of sheets and integral louvers creates at least one tortuous fluid flow channel from an inlet to a vapor outlet of the device An outer casing or frame is sufficient to hold the sheets together.
