This collection of standards includes the language and physics of lighting, vision and visual performance, color science, color appearance and rendition, photometry, non-visual effects of lighting, photobiology, lighting calculations and more. ANSI/IES OL-IM-01
Roadway Lighting design and engineering is unique due to the visual needs at night and the vehicle-to-vehicle and vehicle-to-pedestrian interaction. This standard covers all aspects of roadway lighting including streets and roadways, parking lots, intersections, toll plazas, tunnels, and work zones in addition to the environmental issues of light trespass and sky glow.ANSI/IES OL-IM-05
This Recommended Practice is a compilation of lighting design techniques and criteria, all offered for quality roadway lighting solutions. Each chapter should not be taken in isolation but used as a whole for quality lighting design for roadways and other environments where vehicles are present, such as tunnels, intersections, and parking lots.
A lighting designer will often simplify the design criteria to lighting level and uniformity. However, impacts on visual quality go beyond these simple criteria and encompass minimizing glare and providing spectral contrast on pedestrians, hazards, and other vehicles. All design criteria are important in order to achieve these goals
This Standard was prepared with the objective of providing lighting design guidance for most kinds of roadway and roadway-related applications. The recommendations contained in this document, however, may not reflect specific local factors or situations that are not typical and require special treatment. The contents of this Standard are based upon a consensus of roadway lighting experts. It has no legislative authority unless adopted by an authority having jurisdiction. This Recommended Practice is not intended to establish a basis for civil liability.
This Standard is intended to be a single source of reference for roadway lighting; however, additional documents such as electric codes, transportation design guides, and other codes and standards are often required design references.
Can anyone tell me what version of the IESNA Lighting Handbook we are required to follow for residential "dwelling units" lighting. The Multifamily Energy Model Simulation Guidelines refer to the Lighting Handbook, but not which version. We are working on a v4 project and there is a 1995 verson, a 2017, and a 2020 of the handbook. Does anyone know this or can point me to where the USGBC specifically refers to which version?
Two of the currently available standards for illuminance are KS A 3011, which is the domestic standard of KS, and the standard recommended by IESNA in North America, defined depending on the types of user activities [17]. Neither of the two standards, however, presents a standard on the range of color temperature except experimental researches on the influence of the combination of illuminance and color temperature on human emotions [5]. Hence, it is necessary to design the standard and index of illuminance and color temperature to provide lighting environments appropriate for the user's location and behavior.
Accordingly, this study aims to suggest LED context lighting system that designs contextual lighting environment indexes, automatically recognizes user location and behavior, and creates lighting environments depending on the context. The performance then is evaluated by applying the system suggested according to the lighting control scenario. KS A 3011 is referred to as the standard for illuminance and lighting environment indexes and Kruithof's curve for color temperature [18]. To verify the effectiveness of the suggested system, such factors as illuminance, color temperature, and electric power of wWcW LED that change depending on the dimming control are measured and referred to as the basis for system performance evaluation.
The suggested system involves the five steps of processing as shown in Figure 3. Context acquisition module collects sensing data periodically from the PIR, piezoelectric, and power sensors to recognize user location and behavior. PIR is a sensor of infrared light waves and heat generated from a human body, which are utilized to grasp a user's presence in a certain area of the residential space. A piezoelectric sensor is a sensor that converts vibration into electric signals that is used to trace a user's movement and behavior effectively. A power sensor is used to recognize the user's behavior and alterations in power consumption in linkage with other electric appliances. The sensing data collected from sensors go through the gateway and is transmitted to the LED context lighting system server as input data for user context inference. Table 3 shows the combination of sensors that recognizes various contexts (location, behavior) in five different zones of the residential area [22]. For example, one or more PIR sensors are used at the entrance to recognize a person's staying in or leaving and the number of people in the room. In addition, when a user is watching TV while sitting on the sofa in the living room, a piezoelectric sensor and a power sensor, installed on the sofa and TV set, function to sense whether the user is sitting or turning the TV on/off.
The image quality of Flick's camera is excellent in good lighting conditions although some motion blur, also known as ghosting, takes place when panning. Flick relies entirely on external light since it is not equipped with its own independent light source. The Flick website states that the camera "has exceptional low light performance." The Flick software also offers six color schemes to choose from. Although both of these aspects can certainly be useful, neither of them are a replacement for sufficient lighting in poorly lit environments. This is an especially important factor to consider when considering the fact that Flick is being marketed as a portable solution that can be used in a variety of settings.
Two modes are offered with the OCR option: Reformatted Text and Real Image. Reformatted Text Mode replaces the image of the text with electronic text that is displayed on the screen, and it highlights each word as it is being read. Background color, text color, and text size are additional options that are available with Reformatted Text Mode. Real Image Mode provides the same text-to-speech capabilities as Reformatted Text Mode while retaining the original image of text being scanned. It also highlights each word as it is being read with a red box. Real Image Mode can be a useful feature, allowing you to verify that the OCR is accurately rendering the text that has been scanned while it reads the text. It also provides you with a better sense of what is being read in the context of the material that you have scanned. As mentioned earlier, because the quality of the image is heavily reliant on the lighting conditions available, the accuracy level of the OCR will also be affected by these same factors.
The platform camera block used in the Flick is rated by the manufacturer for low light conditions of 1.5 lux (0.14 foot-candles). Under standardized testing, the Flick consistently recognizes and displays or speaks standard text print (10-14 point font serif or sans serif) with 100% accuracy and with optimum digital contrast even when illuminance is reduced to 1.0 - 2.0 foot-candles (or at 10% of the standard level demand for our user case scenario. In summary, the Flick (as marketed and without any supplemental lighting) demonstrates the capacity for unimpeded reading functionality under any and all educational and vocational task lighting conditions for which minimum illuminance maintenance codes and standards are documented (for North American and Europe). Additional lighting is only required when users are working in dark or near dark conditions.
There are three rows of icons below the top row. VoiceOver recognizes these as a separate list from the top icons because it reports their position (for example, 4 of 13 icons) without taking into account the icons in the top row. Likewise, VoiceOver only alerts you to five icons when you are in the top row. Associated content does not appear for the icons below the first row. You can change the order of the icons beginning in the second row by highlighting an icon and holding down the "Select" button on your remote. Voice Over will announce that you are in Moving Mode, and as you move about with the arrows, VoiceOver will announce what position you have moved the selected icon to. Icons move by switching places with the icon in the direction that you pressed. You can drop the icon by pressing "Select" again, and VoiceOver will alert you that you are out of Moving Mode. 041b061a72
