Disclosed is a lighting assembly for providing electrically configured light distributions and illumination patterns. The light distributions can be pre-configured and stored in a memory device or adjusted once installed in an environment by use of a wired or wireless controller or control device. The lighting assembly comprises at least one primary transmissive optical element and multiple light sources arranged in two or more independently addressed electrical channels spatially arranged on a common plane of the lighting assembly housing. Each light source channel is both physically separated and electrically adjustable in order to control light input into the optical element and subsequently adjust the light distribution output of the lighting assembly. The lighting assembly can be used to provide a wide range of symmetric and asymmetric lighting distributions for direct or indirect lighting as well as focusing or defocusing a projected beam in a spotlight or downlight configuration. The lighting assembly is therefore useful in a wide range of typical indoor and outdoor lighting applications including downlighting, spotlighting, wall washing, cove lighting, retail lighting, warehouse lighting. It is also possible to produce useful tunable white or color related lighting effects wherein different color temperature variants of white or different colors, such as red, green or blue might have different lighting distributions.

Disclosed is a bubble lamp for quasi bubble flow. A buffer made of a transparent material having an excellent heat conduction effect and impact moderating performance is configured on the top of the bulb configured on the main body of the bubble lamp or on the bottom of the glass tube configured on the upper cover, and the casing made of a transparent and no-easily-broken material is put around the glass tube, thereby abutting the glass tube against the top of the bulb across the buffer when the upper cover is covered on and coupled to the main body, allowing both the glass-made bulb and glass tube to be buffered by the butter and thus to block or decrease an impact when a contact force is too large upon assembly, and preventing the bulb or glass tube from being broken.

A lighting system (1) has a first lighting circuit (2) configured to provide a first predetermined level of lighting intensity. The first lighting circuit (2) is configured to receive power from a mains electricity supply (3) or from a battery source (4) if the mains supply is unavailable. The first lighting circuit (2) is connected to at least one first Light source (5) and configured, when actuated, to provide lighting at the first predetermined level of lighting intensity. At this time, the first light source is in either an on or off state or a level of light required to raise ambient light level above a predetermined level. The system (1) further has a second lighting circuit (13) configured to provide lighting at least a second predetermined level of lighting intensity. The second lighting circuit (13) is configured to receive power from the mains electricity supply (3) and is connected to at least one second light source (14). The second lighting circuit (13) has at least one sensor (18) with an input such that actuation thereof causes the second light source (14) to provide the second predetermined level of lighting intensity for a predetermined period of time, in response to ambient illumination meeting or exceeding a predetermined intensity, when said sensor has no input or has had no input for a predetermined period of time, or until re-set. In the system (1), the second predetermined level of lighting intensity is greater than said first predetermined level of lighting.
