What Are the Advantages of Solar Led Street Light Compared

Compared with the traditional high voltage sodium lamps that are widely applied nowadays, the all in one street lights have the following advantages: Firstly, energy saving. Now the luminescent efficiency of the white light of LED is about 80 lm/W, which can save 50% to 60% of electrical power when compared with the traditional high voltage sodium lamps.

my car alarm remote light stays on eventhough it works fine, but the LED stays on on one remote control. Why?

Some remotes do that when the battery gets low. Getting water in might cause the light to stay on too

AC/DC circuits, resistor, capacitor, and relay to light a LED after 3 seconds?

3 minutes? That's fast! From a dead power up mine takes almost 10 minutes to come up all the way. Most of what slows it down are all the programs attached to the start up file, picture sharing, security, external hard drive, spybot programs, quick time and so on and so on. The more you have the longer it takes as each one tries to do its programmed checks. I have not figured it out yet, but there is supposed to be a way to move those programs out of your start up file and make the computer boot faster. I've tried everything I was told with no success

We are trying to set up a new Samsung LED flat screen TV to our Direct TV receiver and a Sony DVD player.?

Direct tv should have an HDMI cable port which you will connect to your tv using HDMI cable. You Sony DVD player depending how old it is might have HDMI cable port also, if not then you will need a component cable (3 rca jacks with the color Red, Green an Blue) for your video connection and use an optical cable for the audio. Your tv will the that input connection also. Check your owners manual of the tv for further instruction. Hope this will help you out

Built new computer, fans work, no beep, no LED's.?

Ah, this reminds me of an old problem I had. Checklist in this order: RAM Connections Chip Cards Board Supply Devices. First thing: make sure all the above are connected solidly (all the way in their sockets), facing the right way around, and not obviously defective. I know one bad stick of RAM can crash a system, one bad PCI card will crash the system, check for a Video Card problem, check your chip to make sure it's seated properly, there's the proper amount of thermal paste on there, that your heat sink is clean, and that the proper connections are in place.

Can You add 2 different LED voltages on one battery?

The first thing you must seem for is if your wallbutton has a mild on it or not. If it does you are going to must change that out to one that doesnt have a light. The wires that run your wall button is very low voltage and can be used to run a light (very small) someplace else. To find your up-limit switch and wire to the open facet with strong core low voltage wire then run the opposite from the wall button and your done

Starting solids when you baby led wean?

when i had my first they said you could start baby rice at 4 months and other baby foods at 5-6 months. With #3 they are now saying to hold off on any baby food till 6 months. But mine started getting rice at about 5 months, and at 10 months is almost off baby food.

Connecting two shift registers in series to glow 16 LED segments?

If they are just glowing - rather than lighting up, you may need to include pull down resistors to keep the outputs low when off

Read state from LED in another circuit

A better solution is an opto sensor attached over the led. You can monitor it without electronically connecting to the circuit. Nothing more than taping a ldr or photodiode over the led.

Tow LEDs are to be connected in series to double the light output. Each LED requires 1.4 volts at 12 mA.HELP?

Oh, Dondi, you are a devil with words. you fairly be attentive to the thank you to make the ladies cry. i think of maybe some adult adult males too, however the macho types could by no skill admit it. captivating. it quite is not any ask your self you are so enjoyed.

  Author :Green earth– LED Strip Lights manufacturersAs far as the LED tube we have seen, there is a structural, internal wiring, anti-electric shock protection, insulation resistance, and electrical strength, creepage distance and electrical gap, heat resistance and refractory. Different LED tubes are different from the light source and materials that determine different price and safety, and the LED tube has a built-in power supply, and the agency different decisions is different.Century Ruiguang Company Engineering Department Li Manager's current technical security issues related to LED tubes, for the type II anti-electric shock type, requires LED tube input contact to reinforce insulation resistance and electrical strength, many built-in power transformers and LED module aluminum substrate Improper installation, causing the test to pass. Or many companies use non-separated power supplies in order to save costs and power efficiency. Internal wiring is mainly linear and insulating thickness, mechanical damage, and insulating layer. The inside is basically can't be in contact with the lamp shell of the aluminum, and the insulation is enhanced. It is also necessary to avoid internal wires and power supply directly to contact the outer casing and prevent the wire from being broken. In terms of structure, it is necessary to prevent insulation of the lamp head, screw, and contact metal surface, and the corresponding lamp head plastic should be used to prevent melting. Since the screws of the LED tube are directly locked, they are required to pay attention to the creepage distance and electrical interval. The internal power supply and the aluminum housing are needed to be separated from the insulating sleeve to reach the power level. The lamp holder and the lamp body are relatively insulated to prevent leakage of the shell.Article Source: LED tube

Eight-meter Solar LED Stream Pole Strength Calculation
  Author :Green earth– LED Strip Lights manufacturersEight-meter solar LED stream pole strength calculationThe following explanation is determined according to GB50135-2006 "Tower Structural Design Specification". Known Conditions are calculated in maximum wind speed V = 36m / s, 12 typhoon. Solar LED Street Light Bar Material Q235 Wait Stress [σ] = 225000kn / m2.Solar LED street lamp lever shape size 8m, light pole height h = 8m, wall thicknessδ5, upper mouth diameter D = 60, lower mouth diameter D = 165 . The upper part of the light pole is in the upper arm length size is l = 1.3M lamp bottom plate flange 420 ×420 .Solar LED street lamp foundation size, foundation profile 0.6m×0.6m, buried depth 1.5m, ground bolt hole distance 320 ×320 , the bolt diameter M24 is four.Solar LED street light pole strength calculation: standard wind pressure calculation, basic wind pressure is W0 = 0.8kN / m2 by wind speed 36m / s, the standard wind pressure W = W0·KT = 0.8×1.1 = 0.88kn / m2. The wind pressure adjustment coefficient KT takes 1.1.The wind calculation of the solar LED street lamp holder stroke light headμS, conical rod body 8.7 wind pressure high speed change coefficientμZ, take 0.9, the light pole is in the wind area S rod = 1.06m2, the street lamp is in the wind area S light = 0.3m2, the light rod is affected by the wind F rod = W·μYes·μexist·S rod = 0.588KN, the lamp head is affected by wind F light = W·μYes·μexist·S light = 0.166knThe total bending moment of the solar LED street lamp lever is calculated, the light pole bending moment M rod = f·H / 2 = 1.176KN·m, the lamp head to the bending moment of the pole, M light = F light·H = 1.328KN·M total bending moment,σM = M rod M lamp = 2.504 kN·NoSolar LED street light pole bending modulus calculation. WZ =πD 4—D4 / d = 3.14×(0.1654-0.1554) / 32/0.165=0.0000976m3.Calculation of solar LED street light pole bending stress. Bending stressσσ=σM / W0 = 25661.8kn / m2σσAs seen from the above calculations, the strength of the solar LED street light pole is sufficient. The geodial bolt intensity check, the wind direction is the diagonal, the tension of the terrain bolt is the maximum N =σM×Y /σY²= 2.504×0.327 / 0.327²2×0.1²= 6045KN, safety factor k take 2.5 floor bolts M24 effective cross-sectional area, s = 314 ², Q235 steel yield limit,σS = 235n / ², Licensed pull N =σYes×S / K = 235×314 / 2.5 = 295KN> n = 645KN, and the ternary bolts are more than four M24.YWX [Excellent Promotion Screen 18013196696]
