A lighting assembly includes a photographic lamp. The photographic lamp includes a lamp body, a first supporting arm and a second supporting arm. The first supporting arm is rotatably connected to a sidewall of the lamp body and capable of rotating around a rotation axis perpendicular to the sidewall of the lamp body. The second supporting arm is rotatably connected to the first supporting arm and capable of rotating around a rotation axis extending along a width direction of the first supporting arm. The rotation axis of the second supporting arm is perpendicular to the rotation axis of the first supporting arm. The second supporting arm includes a first rod and a second rod, the first rod being movable relative to the second rod to realize closing or opening of the second supporting arm.

A lamp with bi-directional light is provided. The lamp includes a body and a head. The head includes a first light source and a second light source. The first light source and the second light source are configured to provide light in directions perpendicular from each other.

A support system for a display device includes a first arm configured to extend from a support surface. A second arm is rotatably connected to the first arm. The second arm has a range of movement relative to the first arm. A tilt head is rotatably connected to the second arm and configured to connect to a display. A first biasing member is positioned in the second arm and configured to provide a first counterbalancing force to the second arm to offset a load of the display. A second biasing member is positioned in the second arm and configured to provide a second counterbalancing force to the second arm to offset the load of the display. A lockout mechanism is configured to disengage the second biasing member and eliminate the second counterbalancing force through at least a portion of the range of movement.

The downlight apparatus includes a surface rim, a rotation bracket, a bowl housing and a light source. The surface rim has an rim edge and a lateral wall. The rotation bracket includes a bracket body and two arms. Each arm has an arm bottom and a arm top. The rotation bracket is attached to the lateral wall. The bowl housing has a bowl edge. The bowl edge defines a light opening. The arm tops of the two arms are attached to the bowl edge. The bowl housing is rotatable with a tilt angle with respect to the arm tops. The light source is mounted inside the bowl housing for emitting a light from the light opening.

An adjustable lamp includes a base, a riser configured to be attached to the base, and an adjustment arm including a lamp head. The adjustment arm is configured to be removably engaged to the riser. The adjustment arm is slidably moveable relative to the riser along a longitudinal length of the adjustment arm such that the distance between the lamp head and the riser can be increased or decreased. The adjustment arm includes a plurality of electrical buses configured for electrical-mechanical engagement with the riser when the adjustment arm is attached to the riser, and the LED lamp head is configured for electrical communication with the plurality of electrical buses.
