Methods and apparatus for implementing a control apparatus for a light fixture for externally controlling the current to the LED light emitter of a landscape LED light fixture. In an exemplary embodiment a control apparatus for controlling current to an LED light source in a landscape lighting device includes an LED driver, a user control with a control setting indicator, and a driver housing including setting indicators.

LED related lighting methods and apparatus are described. Various features relate to water tight light fixtures. Some of the fixtures are spotlights while other fixture are intended for in ground use. The light fixtures in at least some embodiments include power control features. In spotlight embodiments beam angle and power or light output can be controlled without opening the light assembly or compromising the water tight seals which also protect against dirt. In ground embodiments support tilt angle setting which allow a user to set the light fixture to one or more tilt angles. Beam angle can also be changed in some embodiments as well as power control. Beam angle, power control and tilt angle adjustments are supported in some embodiments but need not be supported in all embodiments with some embodiments using one or more of the described features but not all features.

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.

A light emitting diode (LED) bulb includes a connecting body, a lamp cap located at a first end of the connecting body, a mounting base located at a second end of the connecting body opposite to the first end, a plurality of LED modules mounted on the mounting base and a sheath assembled to the second end of the connecting body. The sheath includes a first portion and a second portion detachably engaged with the first portion to cooperatively define an enclosed space enclosing the mounting base and the LED modules therein.

The present invention discloses a method for constructing a universal LED bulb, a flange snap ring type LED bulb and a lamp. A heat conductive bracket (3) with a flange is used as a structure supporting main body of the bulb to establish an optical engine core member of the LED bulb. An inner snap ring (81) fixed to the heat conductive bracket (3) is used to support the optical engine core member in an auxiliary manner. The optical engine core member is composed of the heat conductive bracket (3), an optical engine module (4), the inner snap ring (81), an inner cover (6), an electric connector (11) and a light distribution optical lens (7). The optical engine module (4) is made up of an optical engine die plate, an LED chip and a relevant wiring by bonding and packaging, or is further integrated with a power supply drive chip.

LED related lighting methods and apparatus are described. Various features relate to water tight light fixtures. Some of the fixtures are spotlights while other fixture are intended for in ground use. The light fixtures in at least some embodiments include power control features. In spotlight embodiments beam angle and power or light output can be controlled without opening the light assembly or compromising the water tight seals which also protect against dirt. In ground embodiments support tilt angle setting which allow a user to set the light fixture to one or more tilt angles. Beam angle can also be changed in some embodiments as well as power control. Beam angle, power control and tilt angle adjustments are supported in some embodiments but need not be supported in all embodiments with some embodiments using one or more of the described features but not all features.
