A landscape lighting system includes a plurality of light fixtures, each light fixture having an LED, and a plurality of interchangeable light diverting elements adapted to be secured over the LED. Each light diverting element has a unique light diversion angle associated therewith, whereby only one of the light diverting elements is secured over the LED at any one time. The system includes a light intensity controller for communicating with each light fixture. The light intensity controller has a control element that enables an operator to selectively increase and decrease the intensity of the light generated by the LED.

An illumination system for a projection device is provided. The projection device emits a first waveband light along a first optical path. The illumination system includes a wavelength conversion element, a sequential light-filtering device, and a light guiding device. The wavelength conversion element converts the first waveband light into a second waveband light along a second optical path. The sequential light-filtering device sequentially filters the first waveband light and the second waveband light along a third optical path. The light guiding device guides the first waveband light and the second waveband light along a third optical path or guides the first waveband light to the wavelength conversion element. Consequently, the first waveband light and a first light beam and a second light beam of the second waveband light are sequentially filtered by the sequential light-filtering device and projected out.

A light emitting assembly 100, a lamp and a luminaire are provided. The light emitting assembly 100 comprises a first light source 112, a second light source 118, a first luminescent material 106, a second luminescent material 116 and a light exit window 102. The first light source 112 emits light 110 in a Ultra Violet spectral range. The second light source 118 emits light in a blue spectral range having a first peak wavelength. The first luminescent material 106 is arranged to receive light 110 from the first light source 112 and is configured to absorb light 110 in the Ultra Violet spectral range and to convert a portion of the absorbed light towards light 104 in the blue spectral range. The second luminescent material 116 is arranged to receive light 105 from the second light source 118 and is configured to almost fully convert the received light 105 in the blue spectral range received from the second light source to light with a spectral range of light having a second peak wavelength. The second peak wavelength is larger than the first peak wavelength. The light exit window 102 is arranged to transfer light emitted by the first luminescent material 106 and by the second luminescent material 116 into an ambient of the light emitting assembly 100.

A pivoting rail mounted lighting system for boats which includes three separate portable housings and a light source located in these housings. Each light source being visible from outside the housing such that when the first housing is illuminated, a red colored light source is illuminated for rail mounting to the Port side of the vessel, when the second housing is illuminated, a green colored light source is illuminated for rail mounting to the Starboard side of the vessel, and when the third housing is illuminated, an All Around white light is illuminated for rail mounting to the portions of the vessels railing systems. A quick connect and release pivoting bracket is connected to the housings and is designed to releasably connect to multiple positions along boat railings and allow the light housings to be “pivoted” into the proper direction to display the correct angle of light.
