The present LEDs may consume, for example, about 16 watts of energy. By comparison, a 42 watt CFL consumes 48 watts and a 100 watt metal halide may consume 129 watts. Similarly yet, a 150 watt incandescent lamp consumes 150 watts of energy. This indicates the decreased energy consumption.

The LED light engine also has a longer lamp life in comparison with the 42 watt CFL, the 100 watt metal halide and the 150 watt incandescent lamp. Further, the LEDs 78,78′ have a cooler operating temperature than the fluorescent, HID and incandescent lamps.

Referring now to FIG. 4, a bottom view of the lighting assembly 40 is depicted. Within the heat sink 56 the gasket 60 and projection 62 are visible. The light array or light engine 70 is positioned radially inwardly of the gaskets 60. Also extending through an aperture in the array 70, the power supply connector 76 is depicted for providing power to the array. Also shown in FIG. 4 are the fasteners 48 which extend from beneath the heat sink 56 through the top wall 55 and into the castings 45 of the casing or head 42.

In the embodiment shown in FIG. 4, the LEDs are shown without the reflectors 79 shown in FIG. 2. Alternatively, referring to FIG. 5, the reflectors 79 are depicted positioned all over the LEDs 78,78′ in order to further control and diffuse the light emitted from the white LEDs 78 and the at least one red LED 78′. The combination of light controlling lenses 79 and the diffuse globe 24 creates a great deal of useable light with little to no glare.

Referring now to FIG. 6, a sectional view of a portion of the lighting assembly 40 is depicted. The heat sink 56 is shown with the top wall 55 and the sidewall 57 on an inner surface of the sidewall. The helical thread segments 59 are depicted for receiving of the color mixing diffuser 80 (FIG. 2). On the upper inner surface of the top wall 55 is the gasket element 60. Radially inward from the gasket, and disposed adjacent the top wall 55, is the lower connection plate 66. Opposite the connection plate 66 is the lighting array 70 or light engine. The light engine comprises a plurality of cool light LEDs 78 and at least one red LED 78′. Further, the light engine comprises a power supply connector 76 through which the printed circuit board is powered to drive the LEDs.

The foregoing description of structures and methods has been presented for purposes of illustration. It is not intended to be exhaustive or to limit the invention to the precise steps and/or forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. It is intended that the scope of the invention be defined by the claims appended hereto.

Launching or resupplying food, oxygen, and water into space for long-duration, crewed missions to distant destinations, such as Mars, is currently impossible. Bioregenerative life-support systems under development

worldwide involving photoautotrophic organisms offer a solution to the food dilemma. However, using traditional Earth-based lighting methods, growth of food crops consumes copious energy, and since sunlight will not always be available at different space destinations, efficient electric lighting solutions are badly needed to reduce the Equivalent System Mass (ESM) of life-support infrastructure to be launched and transported to future space destinations with sustainable human habitats. The scope of the present study was to demonstrate that using LEDs coupled to plant detection, and optimizing spectral and irradiance parameters of LED light, the model crop lettuce (Lactuca sativa L. cv. Waldmann's Green) can be grown with significantly lower electrical energy for plant

lighting than using traditional lighting sources. Initial experiments aimed at adapting and troubleshooting a first-generation "smart" plant-detection system coupled to LED arrays resulted in optimizing the detection process for plant position and size to the limits of its current design. Lettuce crops were grown hydroponically in a growth chamber, where temperature, relative humidity, and CO2 level are controlled. Optimal irradiance and red/blue ratio of LED lighting were determined for plant growth during both lag and exponential phases of crop growth. Under optimizing conditions, the efficiency of the automatic detection system was integrated with LED

switching and compared to a system in which all LEDs were energized throughout a crop-production cycle. At the end of each cropping cycle, plant fresh and dry weights and leaf area were measured and correlated with the amount of electrical energy (kWh) consumed. Preliminary results indicated that lettuce plants grown under optimizing

As illustrated in the various figures, some sizes of structures or portions are exaggerated relative to other structures or portions for illustrative purposes and, thus, are provided to illustrate the general structures of the present subject matter. Furthermore, various aspects of the present subject matter are described with reference to a structure or a portion being formed on other structures, portions, or both. As will be appreciated by those of skill in the art, references to a structure being formed “on” or “above” another structure or portion contemplates that additional structure, portion, or both may intervene. References to a structure or a

portion being formed “on” another structure or portion without an intervening structure or portion are described herein as being formed “directly on” the structure or portion. Similarly, it will be understood that when an element is referred to as being “connected”, “attached”, or “coupled” to another element, it can be directly connected, attached, or coupled to the other element, or intervening elements may be present. In contrast, when an element is referred to as being “directly connected”, “directly attached”, or “directly coupled” to another element, no intervening elements are present.

BACKGROUND
Light emitting diodes (LEDs) can be utilized in light emitter devices or packages for providing different color points of light, for example, blue, red, and green light, combinations of light having different color points, and white light (e.g., perceived as being white or near-white). Light emitter devices or packages are developing as replacements for incandescent, fluorescent, and metal halide high-intensity discharge (HID) light products.

Conventional light emitter devices may utilize optical elements such as lenses for improving the amount of light extracted from such devices. One problem with conventional lenses is that the corners of the device submount are not fully improved for light extraction, as conventional lenses fail to extend near or proximate the edges of the submount. Currently, designers and manufacturers of light emitter devices and lighting products are trending towards using and adapting products to which use emitter devices that are dimensionally smaller. Accordingly,

improving light extraction from the corners of the light emitter device submount is becoming more important for maintaining or exceeding expected optical properties, such as brightness levels, expected and required from a given device.

Despite the availability of various light emitter devices in the marketplace, a need remains for devices and methods having improved efficiency and light extraction. Such improvements can be easily scalable to accommodate the demand for dimensionally smaller devices.
