摘要： An apparatus for retrofitting a HID lighting system includes using existing components of previously installed HID lighting systems such as its ballasts while replacing some capacitors to adjust the power supplied to a retrofit LED luminaire. Unused ballast drivers are removed, and a self-contained ballast driver assembly is mounted into the electronic control enclosure of the previously installed lighting system. Some of the retrofit LED luminaires include an uplighting lens, an optic, or a diffuser for providing uplight. An aiming bracket and an aiming plate allow for the horizontal aiming angle of a light luminaire to be set.

摘要： Methods and apparatus for providing circadian-friendly LED light sources are disclosed. A light source is formed to include a first LED emission (e.g., one or more LEDs emitting a first spectrum) and a second LED emission (e.g., one or more LEDs emitting a second spectrum) wherein the first and second LED emissions are combined in a first ratio and in a second ratio such that while changing from the first ratio to the second ratio the relative circadian stimulation is varied while maintaining a color rendering index above 80.

摘要： A pluggable lamp includes a light-emitting tube body, a lamp head and a lamp seat provided at two ends of the light-emitting tube body. The light-emitting tube body includes a heat-dissipating member, a light-emitting plate and a light-transmitting cover. A first mounting groove is opened on one side of the heat-dissipating member. The light-emitting plate has a bottom side overlapped against a groove bottom of the first mounting groove. At least one lamp head pressing element is provided on one side of the lamp head facing the light-emitting tube body, and at least one lamp seat pressing element is provided on one side of the lamp seat facing the light-emitting tube body. The lamp head pressing element and the lamp seat pressing element abut against the top side of the light-emitting plate adjacent the lamp head and the top side of the light-emitting plate adjacent the lamp seat, respectively.

摘要： An LED lighting device comprise a lamp cap; a case, connected to the lamp along in a first direction and having a cavity; a power supply disposed in the case; connected to the lamp along in a first direction and having a cavity; and a light emission unit. The light emission unit and the heat exchange unit are connected to form a thermal conduction path, the light emission unit and the power supply are electrically connected. When the first direction is substantially parallel to the horizontal plane, the light emitting unit of the LED lighting device provides downward light emission. The fixing unit comprises a first member, and a second member, the first member and the second member are in a form of slide connection.
