The present patent application is generally related to lighting, and is more specifically related to landscape lighting systems.
Decorative landscape lighting, when using the common “UP and “Down” lighting techniques, involves the use of different lumen levels and beam spread light sources on different height and width plant materials, architectural details and objects in order to apply the correct light levels that are required when designing a lighting scene. If a designer uses only one brightness level and beam spread light source for all of the small, narrow, wide, and/or tall elements in the landscape, the design would be too bright or too dark and lack any dimension, depth, scale, and detail and essentially become washed out and/or a harsh scene for the human eye to observe at night among the neighboring backdrop of darkness.
Typically, a designer increases the lumen level and beam spreads as they get deeper into the landscape design from the viewing point of a patio or a sitting area and as the scale of the scene increases. Designers want the brightest part of a lighting design to be located at the back and the lowest lighting level to be located in the foreground, which enables the eye to move throughout the lighting scene. In order to direct people around and through a property, allow the human eye to transition through the illuminated scenery, and create focal points in the landscape lighting, designers typically employ different light levels, which requires different beam spreads for the differently sized material that is being illuminated.
Lighting designers typically “build” their lighting designs by starting with lower light levels and wider beam spreads and then gradually increasing the light levels by 30-40% with each subsequent layer of lighting as they get deeper into the depth of the landscape design and property of plant material, scenery and objects and as the plants become larger and wider and the scene evolves, and the light gradually increases in brightness. Additionally, higher light levels are used to create focal or anchor points in a lighting design (e.g., bird baths, statues, gazebos, waterfalls, architecture, fountains, things of interest, etc.), which typically involves using even higher light levels than anything in the surrounding scene in order to draw an observer's eye to the object.
A lighting designer will typically spend a great deal of time identifying a beam spread and lumen value lamp light sources that will then be used to build these lighting scenes. By choosing the most appropriate light levels and beam spreads that work with the item being illuminated, the designer composes a lighting design. The challenge for the designer is that the landscape lights are typically fixed and deliver a given beam spread and lumen level, which cannot be tuned or adjusted in the field to modify brightness levels and/or beam spread. Should the designer want a lower or higher lumen value, or a wider or narrower beam spread, the designer must replace the lamp that is inserted inside the light fixture housing, which involves physically removing the lens/shroud of the lighting fixture. The process of switching lamps to select the right lumen and beam angle becomes confusing if all of the lamps that are used are the same color and there is no differentiating feature or visual indicator on the lamps that allows the installer/designer to quickly and accurately identify the lumen level and/or beam spread of the lamp.
Typically most lamps identify the beam/wattage and lumen by using micro-printed marking that is located at the base of the lamp. A widely used light source in landscape lighting design is a LED version of the popular legacy tungsten halogen MR16 light source that was invented in the 1960's. The designation MR refers to “Mirror Reflected,” and the designation 16 refers to the diameter across the face of the lamp, which is measured in ⅛ths of an inch. For example, the measurement across the face of an MR16 light source is about two (2) inches in diameter.
With the advent of the Light Emitting Diode (LED), lamp manufacturers have essentially mimicked as best they can the beam spread and the lumen value of the legacy Tungsten Halogen MR16 lamps, which are configured for insertion into the footprint of the legacy halogen lamp dimensions so that existing light fixtures could accept the new LED technology and the consumer could upgrade existing systems to the new LED technology.
To date, the lamp bodies of all LED MR16 light sources come in one standard color, such as white, blue or black for every combination of lumen values and beam spreads because manufacturers prefer to order only one MR16 lamp body in order to increase volume and decrease cost of manufacturing.
If, during an installation project, a designer wishes to identify a lumen value and/or a beam spread of a lamp that has been installed in a light fixture, the designer is required to remove the lamp and read the laser etched or printed markings that are located at the base of the lamp, which may or may not indicate the beam spread and the lumen value of the lamp.
Most lamp manufacturers produce a variety of lamps having different beam angles such as Narrow (10-20 degrees), Medium (20-30 degrees), Wide (30-40 degrees), X-Wide (40-60 degrees), and XX-Wide (60 to 120 degrees). In addition, lamp manufacturers published brightness values of the bare lamp and the bare lamps beam spread. The above-noted information that manufacturers provide fails to accurately account for the actual performance of the lamp once it has been inserted into a light fixture, in particular the actual beam spread and the lumen value when the lamp is installed inside an actual lighting fixture.
In view of the above-noted deficiencies, there remains a need for landscape lighting systems that enable lighting designers and installers to quickly, accurately and easily identify lamp lumen values and beam spreads and be able to obtain both information for the bare lumen data and beam data for the lamp and the lumen and beam data for the lamp while in actual operation in a light fixture. In addition, remains a need for improved systems that enable a lighting designer and/or installer to quickly identify the wattage and the associated corresponding lumen value range of a lamp depending on the beam spread without having to read the fine print located at the base of the lamp.
In one embodiment of the present patent application, each lumen value range or light level range of a specific beam angle of a first lamp, such as 70-110 lumen lamp depending on the beam spread, may be identified by a color such as RED and identified as light level #1, or as a 1 wattage LED. Additionally, the lamp may also be referred as having a light output that is akin to that achieved when using a legacy halogen 10 Watt MR16 lamp.
In one embodiment, a second lamp with a next higher level of lumens, which is typically 30% or better than the prior level (i.e., the first lamp) depending on the beam spread with a lumen value of between 128 to 193 may be identified by a color such as GREEN and identified as light level #2, or as a 2 wattage LED. Additionally, the lamp may also be referred as having a light output that is akin to that achieved when using a legacy halogen 20 Watt MR16 lamp.
In one embodiment, a third lamp with the next higher level of lumens, which is typically 30% or better than the prior level (i.e., the second lamp) depending on the beam spread with a lumen value of between 199 to 305 may be identified by a color such as BLUE and identified as light level #3, or as a 4 wattage LED. Additionally, the lamp may also be referred as having a light output that is akin to that achieved when using a legacy halogen 35 Watt MR16 lamp.
In one embodiment, a fourth lamp with the next higher level of lumens, which is typically 30% or better than the prior level (i.e., the third lamp) depending on the beam spread with a lumen value of between to 175 to 421 may be identified by a color such as BLACK and identified as light level #4, or as a 5 wattage LED. Additionally, the lamp may also be referred as having a light output that is akin to that achieved when using a legacy halogen50 Watt MR16 lamp.
In still another embodiment, a fifth lamp with the next higher level of lumens, which is typically 30% or better than the prior level (i.e., a fourth lamp) depending on the beam spread with a lumen value of between to 213 to 575 may be identified by a color such as WHITE and identified as light level #5, or as a 6 wattage LED. Additionally, the lamp may also be referred as having a light output that is akin to that achieved when using a legacy halogen 75 Watt MR16 lamp.
In one embodiment, each lamp may have a specific color assigned thereto. The unique color preferably enables an installer to quickly identify the lumen range of each lamp, which may also depend upon the beam spread of the lamp.
In one embodiment, the one or more markings on the optic of the lamp may be visible when looking at the lamp through the lens of the light fixture in which the lamp is installed. In one embodiment, the specific beam spread may be printed or laser etched on the face of the lamp and is visible, thus being easily identified by a landscape lighting installer. In one embodiment, the beam angle spreads may include N for narrow (e.g., 20 degrees), M for medium (e.g., 30 degrees), W for wide (e.g., 40 degrees), X-W for extra wide (e.g., 55 degrees), and XX-W for extra, extra wide (e.g., 80 degrees). In one embodiment, the reference beam angles for lamps may also be laser etched on the face of the lamp and visible to the installer.
In one embodiment, preferred markings on the optics may be Narrow (e.g., a light beam angle spread of 10-20 degrees), Medium (e.g., a light beam angle spread of 20-30 degrees), Wide (e.g., a light beam angle spread of 30-40 degrees), X-Wide (e.g., a light beam angle spread of 40-60 degrees), and XX-Wide (e.g., a light beam angle spread of 60-120 degrees). This face or top identification of the LED lamp, in addition to the molding of the letters N, M, W, X-W, XX-W in the plastic of the LED optic, may also be stamped, laser etched, molded in the plastic of the optic on the face of the lamp, or indicated by using numbers such as 1, 2, 3, 4, 5, which may be easily identified by an installer once the color of the lamp body is seen (e.g., at the top of the lamp), which in most cases would not require an installer to remove the lamp from the light fixture, thus saving the installer's time when attempting to identify the exact specifications for the lamp that is in use.
In one embodiment, in addition to providing the beam angle on the face of the lamp optic, additional information such as the Correlated Color Temperature (CCT) of the LED may also be identified. Typically, warm white correlates to 2700K, whereby the abbreviation 27K may be provided (e.g., laser etched) on the front optic. In other embodiment, the abbreviations for the color temperatures may be 30K for 3000K, 40K for 4000K, 50K for 5000K, etc. The objective of the color coding of the lamp body, the laser etching of the beam angle, and the identification of the color temperature is to create a fast and easy way for contractors, installers, and end users to organize landscape lighting lamps before, during and after installation to insure accuracy with design and product application.
