A lighting system for generating an illumination product comprises an excitation source, blue/UV LED, operable to generate excitation radiation and a remotely located phosphor, photo luminescent material. Excitation radiation is guided from the excitation source to the phosphor by a waveguiding medium, the waveguiding medium being configured such that the distance the radiation travels from the excitation source to the phosphor layer is at least one centimeter in length. The UV/blue excitation source provides excitation radiation to the phosphor(s), causing the phosphor(s) to photo luminesce, and it may also provide a component of the final illumination product. The configuration of the waveguide allows a greater flexibility in lighting system configurations, such as hanging lighting fixtures, desk lighting fixtures, floor standing lighting fixtures, desk lamps, track lighting, spot lighting, accent lighting, lighting panels, inspection lamps and

Develop Lighting Products that Contribute to Patient Health. When developed and used properly, lighting products can have a positive impact on diagnostic and healing processes. Well-designed lighting can reduce patient stress by mimicking familiar residential lighting, while still taking into consideration aspects of durability, maintenance, and sanitation. Lighting solutions can be specific to a patient care setting, or for surgical, procedural, or diagnostic applications.. Safety concerns for this marketplace include understanding when lighting products will be used near magnetic resonance imaging (MRI) equipment, and developing non-ferromagnetic MRI-compatible lighting products.. In diagnostic applications, the specific spectral power distribution color of lighting is crucial for certain aspects of clinical observation, including the detection of cyanosis - a skin discoloration that can indicate low oxygen levels in the blood. Based on this, the industry has developed methodology for ...
In this video clip I install HID headlights and fog lights in my 2006 Dodge Dakota. The headlights are identified as Bi-Xenon for the reason that the bulbs incorporate each small and substantial beam headlights, the bulb bodily moves back again and forth to toggle small and substantial beams. The headlights have to use the included relay to protect against flickering from Can-bus controlled headlights. The fog lights are not Can-bus controlled so they can be wired right to the vehicles present wiring harness. This is fairly significantly a plug and engage in installation, the only insignificant modifications are for the floor terminals that have to have to be grounded to the body..

Estimates of equivalent illuminants in three-dimensional scenes. (A) Data and fit for one observer redrawn from Boyaci et al. (2003). Observers viewed rendered scenes illuminated by a combination of collimated and diffuse light sources and matched the perceived albedo of a reference surface to a test surface that varied in orientation. The luminance rather than the albedo of the test surface was held constant across orientations. Viewing was binocular. The true azimuth of the collimated source is marked by a green vertical line and the true matching function is shown as a solid green curve. The observers fit matching function has an azimuth estimate close to the true value but is shallower. The equivalent illuminant has a higher diffuseness value than the true value. The fit matching function (dashed red curve) is in good agreement with the data. In particular, the observer is sensitive to the effect of surface azimuth in scenes illuminated by a combination of punctuate and diffuse sources. (B, ...
Car Designers are asking more often for headlamps that adapt well to highly inclined and low vehicle bodies or other exotic shapes e. g. of sports cars. In other cases headlamps are additionally used as stylistic elements and must therefore have a certain appearance e. g. oval shape or a clear, unprofiled cover glass. To realize a headlamp for such applications and at the same time keep it cost-effective with good light quality special headlamp systems have to be developed. Especially the normally used profiled scattering lens in front of the reflector causes complications under these circumstances. Therefore headlamp systems with complex reflector shapes have been developed whose reflectors produce an almost complete light distribution. Some different reflector concepts to realize this idea are presented in this paper and concrete examples for the application of this new technique are discussed ...

There is no production advantage in using fluorescent lights instead of incandescent lights, but the fluorescent tubes or bulbs are more economical to run. Make sure the light shines on all feeders, drinkers and nests. Ducks require a light intensity of about 10 lux and this can be provided by one 60 watt incandescent bulb for every 18 m2 of floor space.. English breeds might panic when the lights go out in an evening lighting program. All-night lighting can prevent such panic, using one 15 watt bulb for every 18 m2 of floor space. If all-night lighting is not practised, morning lighting is preferred to evening lighting. A combined morning and evening lighting program can be used; however, the same problems of possible panic at night must be considered. Blackout training from day one when ducklings are first hatched may prevent later problems of panic when lights are turned off.. Lights should be operated by a time switch that has a reserve spring. Check the lights daily. Remember that daylength ...
This section brings together the various design principles and techniques to provide a practical approach to efficient and effective lighting for the home.. Efficient and effective lighting design means using the most efficient sources with the required controls that will supply the lighting layout desired.. When considering a lighting layout, it is a good idea to focus first on people, then architecture, then art. None is excluded, but lighting a home is primarily for people - to enhance their comfort and communication, as well as to facilitate the daily tasks of eating and working.. In home lighting design, light layering uses four primary layers of light - ambient, task, accent and decorative - and there are some common techniques that supplement and enhance light layering, such as grazing, silhouette and wall washing.. Part of the design process involves controlling the fixtures in an intuitive and appropriate way. The best way to do this is to visualize the space as you carry out day-to-day ...
Total energy consumption in Singapores household system is as huge as 6,560 GWh Among this total energy consumption, the lighting system contributes to 20.9%. The common application of available LED system has a remarkable impact by reducing energy consumption. However, the DC/DC driver in the LED system contributes to system losses and has shorter lifetime than LEDs. Therefore, in this study we proposed novel power distribution for LED lighting system. Compared to commonly available LED lighting system, our novel LED lighting system eliminated the DC/DC driver part. The systematic assessment of LED Lighting System driven by Extra Low Voltage Direct Current (ELVDC) topologies was conducted. Then, electrical characteristics of qualified LED lamps that meet Singapore regulations were applied to the calculation for ELVDC. In order to understand ELVDC feasibility in comparison with AC system for lighting application, we assessed the voltage drop across the cable, system power loss, total ...

Previous ECE regulations also permitted selective yellow light. A research experiment done in the UK in 1968 using tungsten (non-halogen) lamps found that visual acuity is about 3% better with selective yellow headlamps than with white ones of equal intensity.[52] Research done in the Netherlands in 1976 concluded that yellow and white headlamps are equivalent as regards traffic safety, though yellow light causes less discomfort glare than white light.[53] Researchers note that tungsten filament lamps emit only a small amount of the blue light blocked by a selective-yellow filter,[52] so such filtration makes only a small difference in the characteristics of the light output,[54] and suggest that headlamps using newer kinds of sources such as metal halide (HID) bulbs may, through filtration, give off less visually distracting light while still having greater light output than halogen ones.[54] Selective yellow headlamps are no longer common, but are permitted in various countries throughout ...

One of these days, when the state, county or city need money, they could start ticketing people for breaking the law regarding headlight use.I continually see people driving without lights on half-dark, rainy, cloudy days when they should be using their headlights. Not parking lights, but headlights.So many people get in their car and think, I can see. But can the other drivers see you?Many people lose visual acuity as the light decreases. The law says headlights shall be used
This report is a revision and update of CIE 115-1995 "Recommendations for the Lighting of Roads for Motor and Pedestrian Traffic". Since it was issued in 1995 power consumption and environmental aspects have become more important and at the same time, the improved performance of luminaires and lamps, and especially the introduction of electronic control gear, has made it possible to introduce adaptive lighting for roads for motorised traffic, conflict areas and areas for pedestrians. A structured model has been developed for the selection of the appropriate lighting classes (M, C, or P), based on the luminance or illuminance concept, taking into account the different parameters relevant for the given visual tasks. Applying for example time dependent variables like traffic volume or weather conditions, the model offers the possibility to use adaptive lighting systems.. The publication replaces CIE 115-1995 "Recommendations for the Lighting of Roads for Motor and Pedestrian Traffic".. The ...
Lighting choices are critical to any indoor growing operation. Two popular lighting options that many cannabis growers use are light-emitting diodes (LEDs) and high-pressure sodium (HPS). There are advantages and disadvantages to each of these options, and the decision of which is better comes down to personal preference and the specific needs of the growing operation. Here is a look at some of the key differences between these popular lighting setups.. LED Lights. LEDs have been around since the 1960s, but recent technology over the last decade has made this style of light a common favorite with indoor growers. This style of lighting is very efficient and has the ability to convert almost all of the power used for operation into light energy. LED fixtures are designed to require little to no maintenance and generate less heat than other types of lighting. Older styles of LED lights may not produce the appropriate spectrum of light necessary for plant growth, but more recent designs have nearly ...
Another alternative is for programs that do T-Junction detection to have their own cache of detected T-Junctions. So the information would be similar to what I describe above, but the program would automatically do the T-Junction scan any time it loads a part that either doesnt have cached T-Junction data, or where the timestamp has changed. (This is complicated by the fact that the part file itself wont necessarily update; any one of its sub-files could update, so the timestamp information would have to be for each sub-file, not just for the whole part.) This kind of caching could be done by any program, but its a fair bit of extra work that every program author would then have to undergo. Ive actually seriously considered having LDView have an option to auto-cache loaded parts in order to speed loading of files, but never did so due to the complexity involved ...

What is a large, essential, and often unnoticed electricity consumer on DoD facilities? Street and other outdoor lighting. Entire cities have even begun to address this concern with large scale "relighting" projects. Forbes magazine recently published an article about the City of Los Angeles relighting all their public outdoor spaces with LEDs. The city expects to save approximately $8.8 million on its electric bill this year and approximately $3 million in maintenance costs. Similarly, ESTCP along with Virginia Tech and Old Dominion University demonstrated a relighting project, Bi-Level Demand-Sensitive LED Street Lighting Systems that will improve light quality and save on electricity, while sustaining lighting functionality.. Outdoor lighting is important for the safety it provides for nighttime traffic operations associated with pedestrian pathways, roadways, parking lots, storage centers, housing, and perimeter areas. The use of LED lighting dramatically improves sensitivity and image ...
