  • Headlamp Lens Deterioration
    DECEMBER 2018 HEADLAMP LENS DETERIORATION NewsRoom.AAA.com (this page intentionally left blank) 0 Headlamp Lens Deterioration Abstract The average age of registered vehicles in the United States is 11.6 years. Headlamp lenses made of polycarbonate, or plastic, begin to yellow and otherwise show signs of deterioration at five years age (± two). Plastic lenses on automotive headlamps deteriorate due primarily to extended exposure to ultraviolet radiation and abrasion by road grit. The yellowing of the headlamp lenses results in a noticeable decrease in light output. Deteriorated headlamps – when the lens is opaque to the extent that the bulb is not clearly visible – are a safety hazard. This research quantifies the reduction in light output caused by deteriorated (yellowed) headlamp lenses as well as comparing the relative performance of headlamp repair and restoration options available to the consumer. Research Questions: 1. On a vehicle with deteriorated headlamp lenses, how much is light output diminished? 2. Of the options available for headlamp restoration and/or replacement, which one improves light output the most? a. Original Equipment Manufacturer (OEM) replacement headlamp assembly b. Aftermarket replacement headlamp assembly (certified and non-certified) c. Professional restoration d. Do-it-yourself (DIY) restoration Key Findings: 1. Deteriorated headlamps evaluated in this research produced only 22 percent light output (low beam) when compared with new, OEM headlight assemblies. This type of headlamp, halogen reflector, only supports night-time driving (low beam) on unlit roadways at speeds up to 39 miles per hour, when in new condition. A 78 percent reduction in forward lighting is a safety hazard.

  • Do High-Intensity Discharge Headlamps Cause Glare?
    Do High-Intensity Discharge Headlamps Cause Glare? n 2001, the National Highway Traffic Safety Administration (NHTSA) asked the public to submit Icomments about headlight glare and visibility. By April 2002, NHTSA had received more than 1700 responses! The LRC is assisting NHTSA and headlamp manufactur- ers as they weigh the benefits of high-intensity discharge (HID) headlamps and the obstacles they face as the technology matures. The LRC’s work with HID headlamps We have worked with Philips Automotive Lighting to study the effect of HID headlamps on forward visibility. Our work, featured on NBC Nightly News and in USA Today, shows that HID headlamps improve peripheral target detection versus conventional halogen headlamps. In order to understand better how headlamp intensity and spectrum affect visual discomfort, we completed a prelimi- nary study of headlamp glare using halogen, HID, and blue-filtered halogen lamps. Subjects rated their discom- fort levels (1=unbearable, 9=just noticeable) and identified the minimum contrast of objects that were visible with each glare source. The results showed that • Headlamps with more short-wavelength light (~450 nm) resulted in greater discomfort than lamps with less short- wavelength content. Implications • There were no differences among the headlamps in terms If validated in the field, these results could be used to of the minimum contrast that was detectable in the optimize the spectra of HID headlamps to minimize short- presence of glare. wavelength (~450 nm) light while increasing light in the scotopic (~510 nm) region, which could minimize discomfort while improving peripheral detection. NHTSA and headlamp manufacturers will need to continue working together to identify headlamp characteristics that are optimal for visibility while reducing potential for glare.

Page 2 of 66 www.PDHcenter.com PDHonline Course E423 www.PDHonline.org Introduction Gas-discharge lamps are light sources that generate light by sending an electrical discharge through an ionized gas. The character of the gas discharge depends on the pressure of the gas as well as the frequency of the current. High-intensity discharge (HID) lighting provides the highest efficacy and longest service life of any lighting type. It can save 75%-90% of lighting energy when it replaces incandescent lighting. Figure 1 shows a typical high-intensity discharge lamp. In a high-intensity discharge lamp, electricity arcs between two electrodes, creating an intensely bright light. Usually a gas of mercury, sodium, or metal halide acts as the conductor. HID lamps use an electric arc to produce intense light. Like fluorescent lamps, they require ballasts. They also take up to 10 minutes to produce light when first turned on because the ballast needs time to establish the electric arc.

  • Near-Infrared Operating Lamp for Intraoperative Molecular Imaging of a Mediastinal Tumor Jane Keating*, Ryan Judy, Andrew Newton and Sunil Singhal
    Keating et al. BMC Medical Imaging (2016) 16:15 DOI 10.1186/s12880-016-0120-5 TECHNICAL ADVANCE Open Access Near-infrared operating lamp for intraoperative molecular imaging of a mediastinal tumor Jane Keating*, Ryan Judy, Andrew Newton and Sunil Singhal Abstract Background: Near-Infrared (NIR) intraoperative molecular imaging is a new diagnostic modality utilized during cancer surgery for the identification of tumors, metastases and lymph nodes. Surgeons typically use headlamps during an operation to increase visible light; however, these light sources are not adapted to function simultaneously with NIR molecular imaging technology. Here, we design a NIR cancelling headlamp and utilize it during surgery to assess whether intraoperative molecular imaging of mediastinal tumors is possible. Methods: A NIR cancelling headlamp was designed and tested using NIR spectroscopy preoperatively. Next, a 46 year-old-female was referred to the thoracic surgery clinic for a 5.8 cm mediastinal mass noted on chest x-ray. Prior to surgery, she was given intravenous indocyanine green (ICG). Then, the prototype headlamp was used in conjunction with our intraoperative molecular imaging device. The tumor was imaged both in vivo and following resection prior to pathological examination. Results: NIR spectroscopy confirmed NIR light excitation of the unfiltered headlamp and the absence of NIR emitted light after addition of the filter. Next, in vivo imaging confirmed fluorescence of the tumor, but also demonstrated a significant amount of NIR background fluorescence emanating from the unfiltered headlamp. During imaging with the filtered headlamp, we again demonstrated a markedly fluorescent tumor but with a reduced false positive NIR signal.

Knoblauch Director Center for Applied Research 9308 Georgetown Pike Great Falls, VA 22066 Phone (703) 759-2880 FAX (703) 759-2992 Ultra-Violet Headlamp Technology for Nighttime Enhancement of Roadway Markings and Pedestrians Safety on the roadways at nighttime has been a major concern for many years. Motorists driving at night are 2 to 3 times more likely to be involved in an accident at night than during the daytime. About half of the motor-vehicle deaths occur at night; however, death rates based on mileage are about four times higher at night than during the day (1). Nighttime driving is especially frustrating to the older population. The American Association of Retired Persons surveyed 1,400 of their members, and over half of the respondents indicated that they drive less at night due to reduced visibility and problems with glare (4). Detection of traffic control devices and hazards on the roadway is an essential part of safe driving. It has been shown that at night most drivers tend to overdrive their low beam headlights and operate at very short preview times, which could possibly explain the increase in accidents (5). Researchers have investigated ways of making objects and pedestrians more visible at night, thus increasing their preview time for drivers.

  • More Light on the Headlighting Problem VAL J
    More Light on the Headlighting Problem VAL J. ROPER and G. E. MEESE Miniature Lamp Department, General Electric Co., Nela Park, Cleveland, Ohio •IS there any practical way that seeing can be improved with the lower beam? Can the annoyance of headlamp glare be reduced? What is the effect of the headlamp mounting height on today's cars? How about the new quartz iodine headlamps that are being pro­ moted in Europe? How much does alcohol-in the driver-affect seeing distances? Answers to these questions were sought in a recent series of seeing-distance tests using opposing cars with observer-drivers and observer-passengers. The procedure was similar to that described in "Seeing Against Headlamp Glare." (1) Two opposing cars, radio equipped and with the test headlamps, we re started some 4, 000 ft apart on a 2-lane highway, accelerated uniformly to 40 mph with this speed maintained throughout the test run. Test obstacles 16 in. square and with 7 percent reflectance (dark gray) were placed at the right edge of the traveled roadway. There were a total of 10 obstacles, 5 ahead and 5 behind the meeting point. The observer­ driver and observer-passenger ignored the obstacles on the left side of the road. They watched for the obstacles on the right side of the road only and indicated the moment of detection by pushing a button. The button actuated a pen which marked a tape re­ corder geared to the transmission. A sufficient number of repeat runs were made to get a fair average of the seeing distance values as the two cars approached, passed at the meeting point and proceeded beyond.

  • Vibration Resistance of Headlamp Design with Light Emitting Diodes for Electric Locomotive
    Computer Optics and Nanophotonics Vibration resistance of headlamp design with light emitting diodes for electric locomotive Abulkhanov S.R., Skuratov D.L. Samara State Aerospace University Abstract. We determined the natural frequencies of the headlight structure with light emitting diodes (LEDs) for electric locomotive (VL series). We used the ANSYS software system of finite-element analysis for computations. The obtained values of the natural frequencies and the oscillation character of the design on every mode made it possible to determine the design activities that increase the vibration resistance of the design of a headlight. Keywords: a headlight of a locomotive, the natural frequencies of the structure, trouble-free service life, periodic vibration, light-emitting diodes (LEDs). Citation: Abulkhanov SR, Skuratov DL.
