Please my fero pace home , exit, and option led light so I can’t enjoy my adroid phone in the night because i don’t see the option pads down my screen, could it be settings. If you notice a streetlight or outdoor area light is out, please use this form to let us know about the problem. Thank you for helping to keep our community safe. With our novel question in mind, we must then ask how the concept of light pollution frames current challenges and associated ethical questions, and what actions it will guide us toward. However, it is pertinent to first clarify the notion of ‘framing’. Here, I use the term broadly to describe the conceptual lens through which problems will be defined and perceived, and through which solutions will be posed. Frames are helpful in crystallizing and formulating a problem, but in doing so also set the boundaries of possibility on potential solutions. In Frame Innovation (2015 Dorst, K. (2015). Frame innovation: Create new thinking by design. Cambridge: The MIT Press. [Google Scholar]), Dorst explains a method of design thinking used to overcome seemingly intractable real-world problems, dubbed the ‘frame creation model’. Building on the linguistic research of Lakoff and Johnson (1980 Lakoff, G., & Johnson, M. (1980). Metaphors We live by. Chicago, IL: The University of Chicago Press.[Crossref] [Google Scholar]), Dorst explains that frames may be simple phrases, but in reality are subtle and complex thought tools. ‘Proposing a frame includes the use of certain concepts, which are assigned significance and meaning. These concepts are not neutral at all: they will steer explorations and perceptions in the process of creation’ (2015 Dorst, K. (2015). Frame innovation: Create new thinking by design. Cambridge: The MIT Press. [Google Scholar], p. 63). A good frame should be inspiring, original, robust, and create a common space for finding solutions. And once accepted, a frame will define the parameters of possibility. ‘Once frames are accepted, they become the context for routine behavior: once accepted, the frame immediately begins to fade. Statements that started life as original frames become limiting rationalities in themselves, holding back new developments’ (Dorst, 2015 Dorst, K. (2015). Frame innovation: Create new thinking by design. Cambridge: The MIT Press. [Google Scholar], p. 65). Disputes are still common when deciding appropriate action; and differences in opinion over what light is considered reasonable, and who should be responsible, mean that negotiation must sometimes take place between parties. Where objective measurement is desired, light levels can be quantified by field measurement or mathematical modeling, with results typically displayed as an isophote map or light contour map. Authorities have also taken a variety of measures for dealing with light pollution, depending on the interests, beliefs and understandings of the society involved.[citation needed] Measures range from doing nothing at all, to implementing strict laws and regulations about how lights may be installed and used. … public lighting is the single largest source of local government’s greenhouse gas emissions, typically accounting for 30 to 50% of their emissions. There are 1.94 million public lights — one for every 10 Australians — that annually cost A$210 million, use 1,035 GWh of electricity and are responsible for 1.15 million tonnes of CO2 emissions. With the limitations known, we can next consider how to strengthen practical applications. Operating effectively in such a capacity necessarily means establishing the boundaries or thresholds for lighting considered to be ‘polluting’. If we focus solely on mitigating the negative or adverse effects of artificial nighttime illumination, we must then define what qualifies as negative or adverse, as well as what the acceptable levels of these effects are. And these levels—which will effectively delineate between good and bad lighting—should not be arbitrary or ambiguous. 7. By wasted, we can assume this percentage of lighting is deemed to fall within one (or more) of the categories listed above (skyglow, glare, light trespass, or clutter). A common criticism of full cutoff lighting fixtures is that they are sometimes not as aesthetically pleasing to look at. This is most likely because historically there has not been a large market specifically for full cutoff fixtures, and because people typically like to see the source of illumination. Due to the specificity with their direction of light, full cutoff fixtures sometimes also require expertise to install for maximum effect. Determine the frequency of … (GIVEN: 1 m = 109 nm) a. … red visible light (λ = 650 nm) b. … violet visible light (λ = 420 nm) The relationship between safety and lighting at night is complex at best, and often controversial. Historical surveys into the origins of public nighttime lighting (e.g. Ekirch, 2005 Ekirch, R. A. (2005). At day’s close: Night in times past. New York, NY: W. W. Norton & Company Inc. [Google Scholar]) describe the storied relationship between the value of safety and lighting efforts. Lighting served the practical function of making nighttime travel safer, but also the symbolic function of protection from the evils of the night (spirits, demons, etc.). In contemporary discourse, the exact relationship between safety and security and nighttime lighting remains contentious, with various studies proving or disproving a correlation (Pottharst & Könecke, 2013 Pottharst, M., & Könecke, B. (2013). The night and its Loss. In Space-time design of the public city, urban and landscape perspectives (Vol. 15, pp. 37–48). Dordrecht: Springer.10.1007/978-94-007-6425-5[Crossref] [Google Scholar]). It is outside the scope of this paper to comment on these studies in detail, but it is important to note that advocates for mitigating light pollution often cite the possibility that less (or more wisely designed) lighting may improve safety and reduce crime (e.g. Bogard, 2013 Bogard, P. (2013). The end of night: Searching for natural darkness in an age of artificial light. New York, NY: Back Bay Books. [Google Scholar]; Henderson, 2010 Henderson, D. (2010). Valuing the stars: On the economics of light pollution. Environmental Philosophy, 7, 17–26.10.5840/envirophil2010712[Crossref] [Google Scholar]). But what of the details of the transition between the miraculous transmission of light over great distances to the relatively slow pace today, all accomplished on Day Four? Would this imply a transition region that still might be reaching the earth today? Might there be some implication for the Hubble relation, the general trend of increasing redshift with increasing distance? Alas, I do not know. These and many other questions must be addressed for my proposal to be taken seriously by fellow creation scientists. I hope that with time to reflect, discussion with others, and perhaps the work of others on my proposals may yield some insight into these and many more questions. I place this proposal before others to stimulate discussion. We are faced with a new problem: simply put, we have too much light at night. For centuries, more and better urban nighttime lighting was largely seen as desirable and necessary. However, following the rapid proliferation of electric lighting throughout the twentieth century, the impacts of artificial nighttime illumination have become a research interest—or rather concern—in a variety of disciplines. Nighttime lighting uses enormous amounts of energy, in addition to costing billions of dollars, damaging ecosystems, and negatively affecting human health.11. These effects are described in more detail in Section 3.3.View all notes With this emerging knowledge, continuing with the same use patterns and regulatory strategies can no longer be justified. We must rethink our urban nights. But, some amount of artificial light is, of course, still desirable and necessary at night. Therefore, our new problem comes with a novel question: how much artificial light at night is appropriate? The Swiss Agency for Energy Efficiency (SAFE) uses a concept that promises to be of great use in the diagnosis and design of road lighting, “consommation électrique spécifique (CES)”, which can be translated into English as “specific electric power consumption (SEC)”.[99] Thus, based on observed lighting levels in a wide range of Swiss towns, SAFE has defined target values for electric power consumption per metre for roads of various categories. Thus, SAFE currently recommends an SEC of 2 to 3 watts per meter for roads of less than 10 metre width (4 to 6 watts per metre for wider roads). Such a measure provides an easily applicable environmental protection constraint on conventional “norms”, which usually are based on the recommendations of lighting manufacturing interests, who may not take into account environmental criteria. In view of ongoing progress in lighting technology, target SEC values will need to be periodically revised downwards.
