An LED lighting fixture including a housing comprising a single-piece wall structure defining a cavity with an LED-supporting surface therewithin. An LED illuminator is mounted at the LED-supporting surface in the cavity, the LED-supporting surface positioning the LED illuminator in a desired orientation. An LED driver may be secured against the housing which transfers heat therefrom. There may be a plurality of spaced apart LED illuminators mounted at the LED-supporting surface within the cavity. The LED lighting fixture may also include a single-piece reflector comprising a plurality of reflector cups for the LED illuminators and extending therefrom to a common forward end of the housing.

LED lighting fixture

An LED lighting fixture including a one-piece housing portion having a hollow interior cavity defined by a substantially planar interior backwall surface and a surrounding wall extending therefrom to a forward edge. An LED illuminator is on the substantially planar interior backwall surface, a backwall being a heat sink for transferring heat away from the LED illuminator during operation. A one-piece reflector member extends forwardly from the backwall interior surface and substantially across the housing portion to the surrounding wall. The reflector member has a reflector cup and an outward flange secured with respect to the surrounding wall at the forward edge thereof. The reflector cup defines an aperture configured and positioned such that the LED illuminator is exposed therethrough.

An LED lighting fixture including a housing having a hollow interior cavity defined by a backwall and a surrounding wall extending therefrom to a forward edge. An LED illuminator is mounted in the housing. An LED-support structure extends in the interior cavity from the housing to an LED-supporting surface positioning the LED illuminator in a desired orientation and spaced from the backwall. The LED-support structure is a heat sink transferring heat from the LED illuminator to the housing.

An LED lighting fixture comprising (a) a front-housing portion having a surrounding lateral wall defining a front cavity and extending to a front-housing forward edge at an open front-end, (b) a rear-housing portion having a backwall and a surrounding wall which define a rear cavity, the surrounding wall extending to a rear-housing forward edge, the rear-housing portion joined to the front-housing portion with the rear-housing surrounding wall substantially in alignment with the front-housing surrounding wall, (c) a cross-member secured with respect to the housing portions in a position at the juncture thereof and spanning the interior of the joined housing portions, the cross-member having a front surface facing the front cavity, and (d) an LED illuminator secured to the front surface of the cross-member.

A lighting fixture includes a light unit, a supporting frame pivotally coupling with the light unit, and an angle adjustment arrangement including a first gear member provided at the light housing, and a second gear member provided at the supporting arm. The first gear member has a first teething face to match and engage with a second teething face of the gear member. When the first gear member is moved apart from the second gear member, the light housing is adapted to pivotally move with respect to the supporting frame so as to selectively adjust the projecting angle of the light unit. After the projecting angle of the light unit is set, the first gear member is moved back to re-engage with the second gear member to lock up the light unit at the projecting angle.

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.

A High-Intensity Discharge lamp which includes a high intensity discharge light disposed within the light cavity and a standby lighting control system including a light sensor for detecting a light intensity within the light cavity and a standby lamp which is supported within the lamp housing and is activated by the light sensor between a standby mode and a backup mode, wherein at the standby mode, when the light intensity of the high intensity discharge light within the light cavity is above a predetermined threshold, the standby lamp is deactivated, and at the backup mode, when the light intensity of the high intensity discharge light within the light cavity is dropped below the threshold, the standby lamp is activated for generating a backup light to compensate a loss of the light intensity of the high intensity discharge light.

A worklight includes a worklight housing for receiving a light source therein and a worklight stand including a U-shaped supporting leg having a lower supporting base and two upper hinge ends pivotally connected to the worklight housing, and a U-shaped pivot leg having a lower standing base and two upper pivot ends, wherein the two hinge ends of the supporting leg are pivotally connected with the two pivot ends of the pivot leg respectively. The worklight stand further includes a foldable stand and a supporting frame, which is supported on foldable stand, detachably mounted to the supporting base of the supporting leg and the standing base of the pivot leg in space apart manner such that the worklight housing is substantially supported on the supporting frame and is elevated via the foldable stand in a stable manner.

A portable stack lamp includes a base supported by a supporting device, such as an extensible tripod and a plurality of rolling wheels, two or more lamp units stacked up to form a stack-up lamp body mounted on said base, and a cover which is adapted to cover a top opening of the housing of the lamp unit having a handle affixed thereon. The portable stack lamp is arranged to provide 360 degrees illumination so as to produce luminous beams in all directions while the user is able to selectively increase or decrease its luminous intensity by simply stacking up more or less lamp unit easily anytime. Therefore, the portable stack lamp can illuminate the surrounding that not only minimizes the number of work lamps to be used but also saves both the electrical energy and illumination cost. Moreover, each of the lamp unit of the portable stack lamp is arranged to equip a ring type fluorescent bulb as a light source so that it can be used indoor while consuming less electrical energy than the incandescent bulb or halogen bulb of the conventional work lamp.
