Abstract: A multi-sectional artificial tree with a tree lighting system. The tree includes a DC power converter, and lower and upper tree sections. Each tree section includes a tree frame with groups of branches and light sets in a ratio of one light set per branch. The thin, single-conductor wires of each light set are affixed only to a single branch to prevent bending and breaking. Each group of branches and light sets is positioned at a particular height on the trunk of the tree. An upper tree section includes fewer branches per group, as compared to a lower section, and thus includes fewer light sets per group. The light sets are wired in series from branch-to-branch, though the number of light sets per group varies from section to section. Consequently, a resistive load is used in the upper tree section to adjust a voltage applied to individual light sets.

Abstract: A system for lighting a volleyball court has four corner light assemblies, two side center light assemblies, and four mid-court light assemblies. Each corner light assembly has an upper light fixture adapted to emit light outward and downward at a level generally below a player's eye level and a lower light element mounted in a manner to emit light outwards and upwards. Each side center light assembly has two lower light fixtures adapted to emit light outward and downward at a level generally below a player's eye level and an upper light assembly adapted to emit light outwards and upwards at a level generally above a player's eye level. Each mid-court light assembly has a light fixture adapted to emit light outward and downward at a level generally below a player's eye level. By ensuring that no light is emitted at a player's eye level, glare is significantly reduced.

Abstract: An illuminating device for plant cultivation to cultivate plants has a base, a light source, a light converging plate, a position-adjusting device and a distance sensor. A height of the plants is detected by the distance sensor, and then a distance between the light source and the light converging plate is adjusted according to the height detected, and as a result, an illumination field of the light source is altered by the light converging plate. Therefore, an illumination field of the light passing through the converging plate is narrower to illuminate the plants located farther away and prevents waste of light energy. When the plants grow higher, the distance between the light source and the light converging plate is adjusted to provide a wider illumination field to ensure that light can be distributed evenly among the plants. Utilization efficiency of light energy is therefore improved.
