The aforementioned separated type solar street lamp needs a specialized ground buried base for battery and electric wires for connection with the battery, the light source, the crystalline silicon panel and the control system. It is extremely inconvenient for installation and needs a professional technician for on-site installation and debugging. Once it is damaged, a professional technician is again needed for on-site inspection and maintenance. As for the solar street lamp adopting a radiator for heat dissipation, the cost is high and the street lamp is too heavy to move and install. Moreover, the heat dissipation through the radiator causes a great loss of energy.

What turns the street light on and off

Most street lamps have a sensor to trigger it on and off. When it gets dark, the light turns on. When it's light, it turns on. Lasers can turn them off at night because the beam is so bright.

what does it mean when you drive under a street light and it goes out?

It means the light has a bad sensor

If I have a street light post that has two 150 watt light bulbs; how much do I pay?

If it's $.125 per Kwh... 150 x 2 = 300 watts, say 10 hours a night = $.375 (cents) per night $11.25 (30 days), $136.88 per year. I am assuming you have an electric eye sensor turn on. Its probably not worth the money to swap out to a timer to program and save money. You would want a digital one if do go that way and they run $30 or so plus install.

A street light is mounted at the top of a 15-ft-tall pole. A man 6 ft tall walks away ...?

When he is 50 ft away from the poll the answer is 20/3 ft/s

I have a street light that needs a power source. I'd like to use solar instead of hard wire. What system should I use?

Simple answer from a solar user. I would find the wattage of the light and get a battery that can run it for 3 days. Then a solar panel that can charge the battery fully during a cloudy day. I have a portable 150wh suaoki and it charges fully on a cloudy day with a 100 watt panel. I think you might find a 50 watt and 75 wh battery would easily run a light at night permanently depending on the wattage

Why is there a street light in my backyard?

someone requested it put in for light

Why do street light always go out when I walk by?

It's more of a question of. Why do you walk outside when the streetlights go off during the heat cycle of their operation

Do/will you go by the porch/street light rule for your kids?

No. My kids have to check in every hour. I want to know where they are, who they are with and what they are doing. I would love to get my hands on the kids or parents of the kids who roam free in my neighborhood! They ride dirt bikes and 4 wheelers through all the yards and one day rode a push lawn mower down the hill in front of my house, and yes it was running. Kids around here have no common sense and I would like my kids to be more responsible than that.

What does it mean when my car won't move after I come to a stop at a street light?

could be air flow sensor. get it to a Hyundai dealer and get it checked for codes. sounds like a sensor problem

Why do so many people disbelieve in street light interference?

Because it is the prime example of confirmation bias working in concert with optical illusion. The illusion part comes in due to the fact that you're much more likely to notice a streetlight flickering near you rather than ones flickering far away, giving the illusion its only the near ones flickering (streetlight flickering is actually common). The confirmation bias is where you remember all the times that the streetlight next to you flickered but you don't remember all the times that it didn't, giving you the false memory that somehow flickering lights are associated with your presence.

Is this proof that “SLI“ is not real? No, it's not proof. But there is certainly no reason to jump to a fantastic explanation like some kind of psychic phenomenon when it's very well explained with much more likely reasons, as above. Occam's razor applies.

in a street light what does that mean: electricity consumption: 1500 kWh/year.?

A kilowatt is a RATE of using electricity. if you use a kilowatt of electricity for an hour, that is an AMOUNT of electricity. Most electric companies base their cost of domestic electricity on the amount of kilowatt-hours you use.

It is comparable to saying your speed is 50mph. That is your RATE of travel. You cannot ask how far you have gone, about the distance, until you also say how LONG you have traveled at that speed.

So this light is expected, on average, to use about 1500 kilowatt hours each year. Maybe the bulb draws 1,000 watts (one kilowatt) andit is on for 1500 hours a year. But the truth is that that number tells you very little about how much the bulb uses in one hour, or how bright it is: just what it uses in a year.

I hope that helps.

Which wide angle lens and camera combinations are considered to be particularly resistant to artifacts from street light sources?

In general, lenses with superior anti-reflective coatings will reduce the influence of brighter light sources to create flare and reflections within the frame of an otherwise darker scene.Modern lenses designed during the digital photography age tend to have more surfaces with anti-reflective coatings applied to them and those more advanced coatings tend to be more effective than the coatings used on lenses created during the film era.One factor that has necessitated more and better anti-reflective coatings is the higher reflectivity of the front of the filter stacks placed immediately in front of the imaging sensors in digital cameras as compared to the lower reflectivity of most common photographic films. The fact that the sensor stacks in digital cameras are almost perfectly flat does not help any, either. Film, especially roll film, tended to not lie perfectly flat against the camera's back plate unless special steps were taken. Some medium and large format cameras even had suction devices used to hold the sheet negatives or roll film as flat as possible against the back plate.But beyond the differences in reflectivity between film and digital sensor stacks, premium anti-reflective coatings are also a result of the ever advancing state-of-the-art. Advances in what we call nanotechnology have allowed improvements to lens coatings at what many consider a reasonable cost. We make current lenses less subject to flare than lenses in the past simply because we can (and enough buyers are willing to pay a premium to get that improved performance).Canon, for example, has two different nanotech coatings they use. Which one is applied to a particular lens element seems to be based on the amount of curvature of the surface of the lens. This would seem to indicate that one coating is more effective with flatter lens elements, while the other is more effective with elements having more curvature.For more about these two nanotech coating technologies, please see this answer to Why does Canon have Two Kinds of Nanotech Lens Coatings?You can also check out this Canon article that compares the two technologies: ASC: Reduction of Flare and GhostingOther lens manufacturers have their own proprietary lens coating technologies. Nikon calls theirs Nano Crystal Coat. It appears to be similar to Canon's ASC. Sony has Nano AR Coating. Panasonic has Nano Surface Coating. Olympus touted their Zero Coating Nano used in concert with the older ZERO (Zuiko Extra-low Reflection Optical) Coating when introduced in the ED 300mm F4.0 IS Pro. Pentax uses Aero Bright Coating in their most expensive lenses, which they claim costs too much to implement in more budget sensitive products, which use HD Coating instead. One thing you want to avoid, no matter what lenses you use, is placing a flat "protective" filter in the front of the lens. They are notorious for contributing to ghosting and other forms of flare.

Who would i talk to, to get a street light repaired?

Street lamps are usually maintained by the electric company that services your area. Where I live, it depends upon who owns the pole that the light is mounted upon. Could be the electric company, the city or the property owner or a contracted company.

Why does the street light outside my house go out whenever my well-pump turns on?

possibly due to an excees current drain on the line. There is always a voltage drop on a line the further it is from the bssoter transformer. an increase in the demands can cause the light to dim or go out completely. You may need to report it to the electric board who can take steps to prevent this happening by using a backup capacitor system on the light

I have to feed single phase 100 KW street light load by using 3 phase genset.?

Iighting circuits are pretty easy as their load does not change much after reaching the excited state and they do not generally have a large capacitative or inductive element so your power factor will be quite good. I would use a 120 KVA genset or slightly higher. Just to cover the dynamic load of switching them on. Also if it can be arranged do not have them all come on at once. Hopefully these are the type that use ambient light sensors to switch themselves, otherwise I would sequence them. You should split the loads into three to try and maintain as balanced a loading on the three phases as possible. Having an extra 1 or 2 on any phase should not hurt, but split them as equally as possible. Also is your genset giving the correct voltage output on the three phases. It is important not to confuse the phase to phase voltage that will be specced with the phase to neutral voltage.

I hate street light cameras?

probably thought u ran a red light..you can just fight it

When you make a left in Manhattan do you have to wait for the cross street light?

if you have a blinking red you can turn after making a complete stop... if you have a solid red you must wait for the green arrow. Some lights use a blinking yellow which you may treat as a green light without having to make a complete stop first, but realize that the blinking yellow can turn red at anytime.

Can any one tell the circuit of timer controlled street light?

Street lights do not USE a timer... they are on a photo cell, that way they automatically GO ON and GO OFF when the light level reaches a certain intensity

How many days of sun light does it take to power one street light?

It depends upon different lighting systems
