     DETAILED DESCRIPTION 
       [0023]    Embodiments of the present invention generally relate to a landscape light. Specifically, certain exemplary embodiments of the present invention provide various new and novel features for a landscape light, such as a landscape light having laser light sources. Landscape lights according to embodiments of the present invention can, for example, be used as interior or exterior festive and/or decorative lighting in connection with holidays such as Christmas, Halloween, etc. Additionally, the landscape lights according to embodiments of the present invention may be used in place of other traditional decorative lighting, such as string lights, etc. Although the embodiments of the present invention are primarily described with respect to a landscape light, it is not limited thereto, and it should be noted that the exemplary apparatus and systems described herein may be used in connection with any lighting apparatus 
         [0024]      FIG. 1  is an illustration of an exemplary landscape light  10  according to an embodiment of the present invention. As shown in  FIG. 1 , landscape light  10  can include light sources  14  and  16  and lenses  14   a  and  16   a  housed within light projector housing  12 . Although landscape light  10  is shown in  FIG. 1  having only two light source  14  and  16 , landscape light  10  can include any number and type of light sources. For example, landscape light  10  can include one, two, three, or more light sources. Further, each of the light sources can be any type of light source that can produce the type of light desired, such as, for example, light sources  14  and  16  may include lasers, incandescent bulbs, and/or light emitting diodes (LEDs). Optionally, light sources  14  and  16  can produce lights having the same color. Alternatively, light sources  14  and  16  can produce lights having different colors (e.g., red, green, white, blue, etc.). Further, as shown in  FIG. 1 , landscape light  10  can include lenses  14   a  and  16   a,  which can correspond to light sources  14  and  16 , respectively. Lenses  14   a  and  16   a  can include any type of optical element that can manipulate and/or condition the light produced by light sources  14  and  16  in a desired manner. For example, lenses  14   a  and  16   a  can include diffractive features (e.g., diffractive holographic optics) configured to disperse the light generated by light sources  14  and  16  into a plurality of discrete points of light when projected onto a surface. Lenses  14   a  and  16   a  can also scatter the light generated by light sources  14  and  16  so as to lower the power of the light, thereby reducing the potential risk associated with exposure to the light in embodiments where light sources  14  and  16  may include lasers. 
         [0025]    According to certain embodiments of the present invention, in operation, landscape light  10  can project light produced by light sources  14  and  16  onto a target surface. For example, light produced by light sources  14  and  16  may be manipulated or conditioned by lenses  14   a  and  16   a  and be projected onto a target surface, such as a wall or other structure. In an embodiment where lenses  14   a  and  16   a  include diffractive elements configured to disperse the light generated by light sources  14  and  16 , landscape light may project a plurality of discrete points of light onto the target surface. Landscape light  10  may also include various modes of operation. For example, landscape light  10  may include mode where the lights produced by light sources  14  and  16  can be flashed, strobed, or pulsed at predetermined, or randomized intervals. This may be performed by modulating the power delivered to light sources  14  and  16  in accordance with the desired flashing, pulsing, or strobing pattern. Additionally, landscape light  10  may also a visual effect assembly, which can produce various visual effects using the lights produced by light sources  14  and  16 . For example, visual effect assembly may be configured to produce a shimmering effect of the light, a movement of the light across the target surface, a “raining” effect of the light, etc. Visual effect assembly may also be configured to produce the flashing, pulsing, or strobing pattern of the light in addition to or in place of any power modulation techniques utilized to achieve these effects. 
         [0026]    As shown in  FIG. 1 , landscape light  10  can also include mounting bracket  20 , ground stake  22 , and power cord  18 . Power cord  18  can be connected to a power supply or transformer (not illustrated). Optionally, landscape light  10  can include a wireless remote control  30 , which can enable wireless control of landscape light  10 . As shown in  FIG. 1 , ground stake  22  and light projector housing  12  may be rotatably coupled to mounting bracket  20 . This can allow user to aim and adjust the direction of the light produced by landscape light  10 . For example, the angle of light projector housing  12  can be adjusted relative to mounting bracket  20 , and mounting bracket  20  can be rotatably adjusted relative to ground stake  22 . Thus, landscape light  10  can be adjusted in two degrees of freedom to provide nearly a full range of motion of adjustments. This can enable a user, for example, to adjust and aim the light produced by landscape light  10  to be projected on various targets even after it has been staked into the ground. 
         [0027]    Additionally, landscape light  10  can include a wireless remote control  30  that can enable wireless operation of landscape light  10 . For example, landscape light  10  can include a wireless transmitter/receiver, which can wirelessly communicate with a remote control  30  to enable wireless operation of landscape light  10 . For example, the wireless transmitter/receiver can employ radio frequency (“RF”), Bluetooth, and/or WiFi technology to facilitate wireless communication between landscape light  10  and remote control  30 . According to certain embodiments, landscape light  10  can be wirelessly operated via remote control  30 . For example, remote control  30  can control powering landscape light  10  ON and/or OFF, changing the operation of light sources  14  and  16  (e.g., choosing between having one of light source  14  or  16  in an ON condition or having both light sources  14  and  16  in an ON condition), controlling a visual effect setting (e.g., flashing, movement, shimmering, strobing, etc.), controlling a timer setting, etc. Further remote control  30  can indicate and display the current operating status of landscape light  10  (e.g., whether or not landscape light  10  is ON or OFF and/or the mode of operation). According to certain embodiments, remote control  30  can be implemented via an app on a mobile device such as a smartphone or tablet, or via a web-based application on a computer. 
         [0028]      FIGS. 2A and 2B  show cut-away views of an exemplary landscape light  210  having a visual effect assembly  220  and light source  230  in accordance with an embodiment of the present invention.

Further, visual effect assembly  220  can create and/or produce visual effects using the light generated by light source  230 . For example, visual effect assembly  220  can create a flashing, pulsing, or strobing pattern, a shimmering effect, a movement of the light across the target surface, a “raining” effect, etc. According to certain exemplary embodiments, visual effect assembly  220  may include an optical element  222 , which may include any optical features (e.g., holographic elements, diffractive elements, patterns, etc.) that can be used to create the desired visual effect. Further, optical element  222  may be coupled to a motor, or other articulating element, that can cause optical element  222  to be articulated in a defined manner, which when combined with the optical feature of optical element  222 , can create the desired visual effect. As noted herein, visual effect assembly  220  can create a flashing, pulsing, or strobing pattern, a shimmering effect, a movement of the light across the target surface, a “raining” effect, etc. As shown in  FIGS. 2A and 2B , optical element  222  may include a disk having optical features disposed thereon, which can be rotated in front of light source in the direction of arrow A to create various optical effects as the light generated by light source  230  interacts with rotating optical element  222 . Although visual effect assembly  220  is shown to include a rotating optical wheel, visual effect assembly  220  can include any structure or programming that can enable creating the desired visual effects of the light. 
         [0029]      FIG. 3  shows an exemplary landscape light  310  according to an embodiment of the present invention. Similarly to landscape light  10  shown in  FIG. 1 , landscape light  310  includes housing  312 , light sources  314  and  316 , and ground stake  322 . Additionally, landscape light  310  includes spotlights  332  and an adjustment mechanism  340 . Spotlights  332  may include any type of light source having sufficient power to illuminate a desired area. For example, spotlights  332  may include light-emitting diodes (LED), halogen bulbs, high-intensity discharge gas lamps, etc., which may illuminate an area in which the light generated by light sources  314  and  316  are projected. For example, spotlights  332  may illuminate a surface such as a wall, and a plurality of discrete points of light generated by light sources  314  and  316  may be projected on the wall within the area of illumination. In operation, spotlights  332  may be configured to be operable in a continuously on state, a flashing mode of operation, varying levels of brightness/intensity, etc. Operation of the spotlights  332  can be in addition to and can augment any visual effects that can be produced/created as described herein. Further, certain visual effects (e.g., flashing, movement, etc.) can be implemented on the light generated by light sources  314  and  316  as well as the light generated by spotlights  332 . 
         [0030]    Further, as shown in  FIG. 3 , landscape light  310  can include adjustment mechanism  340 .

As shown in  FIGS. 4A-4D , landscape lights  410  and  410   a  are similar to landscape light  10 , but include pattern generation assemblies  450  and  450   a.    
         [0032]    Pattern generation assemblies  450  and  450   a  can create patterns in the light produced by the light sources of landscape lights  410  and  410   a,  thereby enabling landscape lights  410  and  410   a  to be project light in specific patterns and shapes. For example, as shown in  FIGS. 4A-4C , pattern generation assembly  450  may include pattern generators  452  mounted on a slide cartridge  454 . Slide cartridge  454  may be configured to be received in cartridge receiving mount  456 . Further, each of pattern generators may include a silhouette or outline of a specific pattern.
