A luminaire having an electronically adjustable light beam distribution is disclosed. In some embodiments, the disclosed luminaire includes a plurality of solid-state lamps mounted on one or more surfaces of a housing. The lamps can be electronically controlled individually and/or in conjunction with one another, for example, to provide highly adjustable light emissions from the luminaire (e.g., pixelated control over light distribution). In some cases, a given solid-state lamp may include tunable electro-optic componentry to provide it with its own electronically adjustable light beam. One or more heat sinks optionally may be mounted on the housing to assist with heat dissipation for the solid-state lamps. The luminaire can be configured to be mounted or as a free-standing lighting device, in accordance with some embodiments. In some embodiments, the aperture through which the lamps provide illumination is smaller than the distribution area of the solid-state lamps of the luminaire.

Of the various technological features disclosed in the present specification, a structure according to the one technological feature is as follows. A lighting apparatus changeable between an illuminating state and a non-illuminating state comprising: a non-contact motion sensor arranged to sense a movement of a hand near the lighting apparatus; and a controller arranged to control the lighting apparatus in the non-illuminating state to change from the non-illuminating state to the illuminating state in response to the movement of hand sensed by the non-contact motion sensor, and to control the lighting apparatus in the illuminating state to cause a change in illumination with the illuminating state kept in response to the same movement of hand sensed by the non-contact motion sensor.

Solid-state lamps having an electronically adjustable light beam distribution are disclosed. In accordance with some embodiments, a lamp configured as described herein includes a plurality of solid-state emitters (addressable individually and/or in groupings) mounted over a non-planar interior surface of the lamp. The interior mounting surface can be concave or convex, as desired, and may be of hemispherical or hyper-hemispherical geometry, among others, in accordance with some example embodiments. In some embodiments, the heat sink of the lamp may be configured to provide the interior mounting surface, whereas in some other embodiments, a separate mounting interface, such as a parabolic aluminized reflector (PAR), a bulged reflector (BR), or a multi-faceted reflector (MR), may be included to such end. Also, the lamp may include one or more focusing optics for modifying its output. In some cases, a lamp provided as described herein may be configured for retrofitting existing lighting structures.

The present invention relates to a backlight module and a corresponding liquid crystal display panel. The backlight module includes a backboard having multiple concave portions formed on an inner surface of the backboard and multiple light sources mounted in the concave portions. The backlight module and the corresponding liquid crystal display device of the present invention can reduce the thickness of direct-type backlight module without affecting the optical quality of the lights emitted from the backlight module and increasing the manufacturing cost of the backlight module.

In an imaging device, a tilted surface is formed on one surface side of a base, while a flexible substrate arranged with light sources is secured along the tilted surface of the base, so as to adjust the optical axis of an imaging unit and positions illuminated by the light sources. Thus, the respective optical axes of light sources are regulated not individually but at once by placing the substrate along the tilted surface, which makes it easy to adjust the illumination positions. It is also excellent in heat dissipation of the light sources, since the heat generated by the light sources dissipates through the base. This enables the light sources to keep their output stability favorably.
