A flexible cover for a linear lighting channel is described, as are enclosures and luminaires using this kind of flexible cover. The flexible cover has sufficient flexibility to be bent or coiled to a bend radius of 6 inches (15.2 cm) or smaller, and can thus be coiled for shipping and uncoiled for installation. Typically, the cover is made of a polymer that is at least translucent. Covers may be made in various shapes, including lens and prism shapes, and channels may be made with sidewalls that make complementary shapes in order to engage with and retain the covers.

A light-emitting circuit includes first and second light-emitting element strings respectively configured to emit light having a first and second color temperatures; a rectifying circuit configured to rectify a voltage, input by an alternating current (AC) power source, to generate a driving voltage; a string switching circuit configured to select at least one light-emitting element string to be used for light emission from among the first light-emitting element string and the second light-emitting element string; an off/on sensing circuit configured to change a selection of the string switching circuit to change a color temperature of light, which is emitted by the light-emitting circuit, when the AC power source is turned off and then turned on; and a driving circuit configured to turn on, in turn, light-emitting elements in the selected at least one light-emitting element string, according to a change in the driving voltage over time.

Techniques are disclosed implementing a lighted guard system, which changes from one color (e.g. white) when the guard is down (i.e. closed) and/or a machine associated with the guard is operational, to another color (e.g. red) when the guard is up (i.e. open) and/or the machine associated with the guard is not operational. The triggering of the change in state of the guard may be facilitated by a switch that changes state based upon a position of the guard.

A wire and a stripping method thereof, and a light strip are provided. The stripping method includes the following steps: holding a wire by a holder, the wire including an insulation layer and a conductor covered by the insulation layer; mounting the holder on a worktable of a an optical device; and activating a light emitter of the optical device to emit a light beam irradiating onto the insulation layer to ablate a portion of the insulation layer to form at least one through hole that penetrates the insulation layer to expose a portion of the conductor.

A dual-color light string comprising a first insulated electrical wire cord, a second insulated electrical wire, two light-emitting diode devices (LED devices) and transparent glue. The first insulated electrical wire is partially exposed to form a first soldering section. The second insulated electrical wire is partially exposed to form a second soldering section. The two LED devices are respectively electrically connected to the first soldering section and the second soldering section, and the directions of bias of the two LED devices from the first soldering section to the second soldering section are opposite to each other; The transparent glue covers the two LED devices, the first soldering section and the soldering section, extends to partially cover a first insulating layer of the first insulated electrical wire and a second insulating layer of the second insulated electrical wire.

A light string, comprising a first illumination device configured to emit a first color light; a second illumination device adjacent the first illumination device, and configured to emit a second color light, the second color being different from the first; a first wire including a first conductor and a first insulating layer, the first conductor partially exposed to form a first conductor soldering section; and a second wire, including a second conductor and a second insulating layer, the second conductor partially exposed to form a second conductor soldering section. The first conductor soldering section and the second conductor soldering section are attached to a pair of electrical contacts on each of the first and second illumination devices, and the first and second illumination devices are electrically biased such that either the first illumination device emits light or the second illumination device emits light, but not both at the same time.
