3. Do streetlights turn off and on when you get near them, more often than seems normal? Can anybody prove the existence of street light interference?

Hi, 15-year lighting industry veteran (and lifelong lighting geek) here to explain.What you're experiencing is a phenomenon that can occur in HID lighting (Mercury, Metal Halide, High Pressure Sodium). Most likely it's under High Pressure Sodium (HPS) light, which is amber in color. Conventional HPS lamps usually begin to cycle at the end of their life. The lamp will extinguish, it will cool off, then start to warm up again, usually coming on in a rush with about 1/4 of it's normal output, then warming back up. The older the lamp gets, the higher the current requirement, the more frequent the cycling. A lamp that's just getting old might only go out a few times a night... but one that's further along can cycle constantly. (Estimated lamp life is 24,000 hours, or about 6 years.)Cycling is caused by aging of the lamp, which increases the current the lamp needs to operate. The ballast is designed to give only a certain amount of current. When a lamp's required current exceeds the current available from the ballast, the lamp goes out, cools down, then eventually fires back up again.This is normal at he end of life of HPS lamps. That lamp will cycle all night, whether you're there or not. You've got nothing to do with it (sorry if that bums you out!)I recommend reporting the light(s) that you've noticed to your local utility or city. Give them some time and try again. If they are re-lamped, then they should stay nice and bright, even when you're there. Side note - HPS was the most common street lighting source... but it's rapidly being replaced by LED street lighting... when that happens in your community, you shouldn't experience these types of things anymore.Do streetlights turn off and on when you get near them, more often than seems normal? Can anybody prove the existence of street light interference?

4. how do you find the shadow of a 5 ft tall person if he or she is 30 ft away from a 20 foot tall street light?

To find the answer, use trigonometry and Pythagoras

5. How to choose LED street light head? - Wenzhou Walton Electrical Co., Ltd.

LED street lamps are an important lighting facility for urban road lighting. Nowadays, LED street lamps are used in parks, courtyards, squares, schools or residential areas. The assembly of LED street lamps is also very simple. The lamp holder of LED street lamps can be realized by adding lamp poles. But many people do not know how to choose the right LED street light head. So what are the buying tips for LED street lamp holders? Let's introduce it to you. Lamp body: LED street lamp heads are all made of aluminum alloy die-casting, which can effectively dissipate heat, waterproof and prevent dust. The surface of the lamp body is painted or anodized, as well as anti-ultraviolet and anti-corrosion treatment, so that the LED street light lamp holder reaches the IP65 standard, which extends the normal operating life of the LED and electronic parts inside the lamp holder. Face shield: The face shield of the LED street light lamp holder should be made of high-strength tempered glass material. This glass material has been specially processed, and will not produce light spots and flowers during lighting. The light transmittance is close to 100%. Such LED street light lamp double bulb holder can be dust-proof and waterproof , explosion-proof, protect the internal structure of the lamp holder, and extend the service life of the thread bulb holder. Chip: The LED street light lamp head uses a high-lumen chip, which can effectively improve the light efficiency; the internal uses ultra-thick double gold wire connection to increase the current flow. This LED street light has a stronger and brighter lighting effect, a more stable light, and a lifespan. Longer; Lens: The lens is very important in the LED street lamp head. It is related to the utilization rate of the light. Generally, an optical lens is used. Such a lens can reasonably distribute the light, make the light distribution more uniform, and increase its illumination brightness. Heat dissipation: LED street light lamp caps generally use industrial-grade heat dissipation technology, which has very good thermal conductivity, which can make the heat in the LED street lamp caps better convection with the outside air, shorten the heat dissipation time, improve the heat dissipation efficiency, and ensure the use of LED street lights life. Protection: LED street light lamp holder contains high-quality silicone sealing ring and respirator. The professional design of LED street light lamp caps guarantees IP65 protection level during the life cycle, which not only guarantees good lighting performance during the life cycle, but also reduces the life cycle and cost of LED street lamp cap maintenance. Power supply: Waterproof power supply, reliable and durable, high power supply efficiency, low power loss, LED street outdoor bulb holder adopts two-stage PFC design, electronic components and related materials are sophisticated, anti-grid surge protection, to ensure the service life of the lamp. The LED market is really full of vitality, and today's LED street lights have begun to become the main force of the national lighting. I believe that in the future development, led tube light holder and led strip light holder will become mainstream.

Problems of Phased Array Ground Penetrating Radar Detection System
Although GPR has been widely used in hydrology, engineering, environment and other fields, many basic theoretical and technical problems have not been fundamentally solved, so the real advantages of GPR have not been brought into full play.The main problems existing in GPR technology include:1) The detection depth is shallow, and the contradiction between detection depth and resolution cannot be overcome. Increasing detection depth means sacrificing detection resolution;2) Multiple spread and other clutter jamming are serious, and there has been no good elimination method, which exists in radars at home and abroad;3) The influence of medium unevenness is great and can not be eliminated, resulting in difficulty in obtaining necessary velocity data;4) The data collection method of single sending and single receiving can provide limited information for post-processing and interpretation.The above problems are fatal defects for GPR. Although many geophysicists, electromagnetic experts and geophysical workers have done a lot of research and improvement on radar antenna design, signal processing and underground target imaging, these works are only partial modifications to the existing GPR system. In order to develop GPR technology, we must update our ideas and solve the problems from the fundamental principle.In view of this situation, experts proposed to develop a new GPR system - phased array GPR detection system in 1999.The basic research idea is to replace the current monopole radar antenna with the phased array radar antenna by using the relatively mature military phased array radar technology. Its purpose is to gather the electromagnetic wave into a narrow beam to transmit underground (or detection object) through the phased array technology, and receive the radar echo signal reflected by the target by using the multi-channel acquisition technology, The advanced data processing is carried out, and finally the three-dimensional image of the internal structure of the detection object is given.Development prospect of ground penetrating radar technologyIt is worth noting that at present, similar products have appeared in the market, such as RIS antenna array series of a company, but these products simply combine multiple monopole antennas into array antennas, which is essentially different from the idea of phased array ground penetrating radar.Because the phased array radar converges the electromagnetic wave into a narrow beam by controlling the phase delay of each channel, the energy is concentrated and the wave front diffusion is small. Therefore, the detection depth of the phased array radar is much larger under the condition of the same frequency and transmission power; On the contrary, under the same detection depth, phased array radar can improve the transmission power, so its resolution is much higher than the existing radar. In addition, since the spherical wave transmission is changed to beam transmission, the influence of medium heterogeneity is much smaller.Secondly, the phased array radar works in a continuous scanning mode and can scan in multiple directions. Therefore, the amount of information is much larger than that of the existing ground penetrating radar. For some special detection work, such as the quality detection of embankment cut-off wall, its role is unmatched by the existing ground penetrating radar (monopole antenna radar can not detect the joints, forks and other defects of embankment cut-off wall at all).Because phased array radar is a multi-channel received signal, multi-channel superposition can be carried out, just like the multiple coverage technology of reflection seismic exploration. Therefore, multiple interference can be greatly eliminated, which is difficult for existing radars. The antenna of high frequency (600mhz-1ghz) phased array ground penetrating radar can be made smaller, and its advantages are unmatched by the existing ground penetrating radar in shallow detection.At present, the system prototype has been completed. The carrier free pulse working system with center frequency of 900MHz is adopted, and the transmitting and receiving antennas are separated. 16 (4 × 4) Transmit channel forming, beam aggregation and scanning 16 (4) × 4) The channel receives the echo, and the optional scanning angles are - 36 °, - 24 °, - 12 °, 0 °, 12 °, 24 ° and 36 °.The software part of the system has rich data processing functions. The main conventional processing includes filtering, gain adjustment, static and dynamic correction, deconvolution, complex signal analysis, time-frequency analysis, etc., and multi-channel data processing, such as velocity analysis, superposition technology, coherence analysis technology, array signal processing, etc. And weak signal extraction, target automatic recognition and inversion interpretation under various clutter interference. A large number of field experiments on concrete detection in Yichang Three Gorges dam are carried out. The experimental results show that the spotlight scanning function of phased array radar has been realized, the penetration depth is greater than 1.5m and the resolution is higher than that of ordinary radar.Editing: hfy
