Apparatus and methods for lighting. The apparatus may include an LED light source. The light source may be disposed in housing. The apparatus may include a circuit. The circuit may be configured to cause the LED light source to emit light at: a first intensity; and a second intensity that is different from the first intensity. The apparatus may include a mechanical power state selector. A user may use the power state selector to select between LED light sources that are arranged to illuminate in different directions. The apparatus may include a CCT state selector. A user may use the CCT state selector to select a CCT for one or more LED light sources. The CCT may be produced by combining light from one or more LEDs of different CCTs.

An illumination lamp includes: a frame-shaped body provided with a first guide portion; and a function portion provided with a light emitting portion emitting light and a first guided portion. The first guided portion is engaged with the first guide portion in a state where the function portion is installed in the frame-shaped body, so that a change in the posture of the function portion with respect to the frame-shaped body is regulated around a predetermined axis.

A simulated flame and wick device for use with a flameless candle and other devices requiring the appearance of a natural flame. A flame shaped housing, comprising an upper and lower cover, contains a flexible LED filament bulb, with the positive and negative leads passing through dedicated channels within a housing designed to have the appearance of a candle wick. The combination of the material used for the wick housing along with the positive and negative leads from the flexible LED filament bulb are designed to provide strength and flexibility to the wick component. In turn these leads pass through a positioning housing to orient the simulated flame and wick correctly when used with flameless candles and other devices. The simulated flame and wick along with the other components described are contained within the internal housing of a simulated candle shell or other appropriate device, thus simulating the appearance of a flame burning atop a blackened wick.

A light source apparatus includes: a first light source; a second light source configured to emit light having a dimming resolution lower than a dimming resolution of the first light source; a holder configured to hold the first light source and the second light source on a first surface of the holder; a substrate provided to face a second surface of the holder, the second surface being different from the first surface, and a circuit configured to control driving of the first light source and the second light source being mounted on the substrate; a first wiring configured to electrically connect the first light source and the substrate; and a second wiring configured to electrically connect the second light source and the substrate, wherein a length of the first wiring is shorter than a length of the second wiring.

A system and method for an accent lighting system is provided. The system includes a plurality of underwater luminaires each having a plurality of light emitting diodes, and a junction box controller housing a plurality of electrical components for generating electrical signals for controlling the plurality of underwater luminaries. The junction box controller can be mounted to an electrical conduit and a plurality of cables can connect the plurality of underwater luminaires with the junction box controller. An underwater luminaire can include a heat sink and a flexible circuit board having a plurality of light emitting diodes mounted on the heat sink. The flexible circuit board transfers heat from the light emitting diodes to the heat sink. The underwater luminaire can also include a wiring harness for connecting the underwater luminaire to a cable. The underwater luminaire can also include a housing having a lens positioned at one end, an end cap mounted to an opposite end of the housing. The housing and the end cap can form a waterproof enclosure for the heatsink, the flexible circuit board, the plurality of light emitting diodes, and the wiring harness.

A linear light apparatus includes a light strip, a light passing cover, a main bracket, a bottom holder and a metal clip. The light strip having an elongated substrate mounted with LED modules. The main bracket holds the light strip for the LED modules emitting a light passing through the light passing cover. The metal clip has a first thorn and a second thorn. The metal clip is pressed to one side wall for the first thorn to stab a second insulation layer to electrically connect the bottom holder and the metal clip. The second thorn stabs a first insulation layer for the metal clip to be electrically connect to the first metal part of the main bracket.

A luminaire can include a power supply that receives AC mains power from a power source and delivers intermediate power, and can also include a lumen control module coupled to the power supply, where the lumen control module receives the intermediate power from the power source. The lumen control module can include at least one first switch that has multiple positions, and multiple resistors coupled to the at least one first switch, where each position of the at least one first switch corresponds to a resistance of the resistors, where the intermediate power received by the resistors is translated to a current level of a plurality of current levels based on the resistance. The luminaire can also include at least one light source coupled to the lumen control module, where the at least one light source emits a lumen output based on the current level received from the lumen control module.

A grow lighting system for use with plants includes an elongated body for positioning adjacent a plant. The elongated body defines multiple lighting channels extending the length of the body. Linear grow lighting sources, such as grow lighting LED strips, are removably positioned in a corresponding lighting channel. Each linear lighting source is oriented to emit light radially outward from the body. The fixture body can be suspended generally vertically.

A method and apparatus for an indoor horticultural system that utilizes a wired network to control lighting. The wired interface is used to relay both analog and digital intensity control information, whereby an analog signal is used to control the intensity of all LED arrays in each lighting fixture during a first mode of operation and a digital signal is used to control the intensity of each individual LED array in each lighting fixture in a second mode of operation. Both the analog and digital signals utilize the same physical interface.
