Q:How big wires should fifteen LED street lights require?
Yes, you need to know what the power value is for each or 15 street lights
Q:LED street light dedicated drive power 98W14 string 7, and ask 14 string 7, and what does that mean?
The 14 LED are connected in series to calculate a set, and then there are seven groups, which connect the seven sets of positive and negative electrodes to the negative pole, i.e., the seven groups are connected in parallel, and this is the meaning of "14 strings of 7".
Q:LED lights at home after the power cut slightly bright, and the original street lights related, street lights LED lights, street lights off, led pass, how to solve?
LED lights turn off the light: 1, the switch is cut off the zero line, you can change the line.
Q:Features of LED street lamps
LED street lamp is different from conventional, LED light source adopts low voltage DC power supply, by the high white GaN based blue LED and yellow synthesis, has the advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index unique advantages, can be widely used in the road. Cover can be made, high temperature up to 135 degrees, low temperature resistance up to -45 degrees. 1, the characteristics of its own - one-way light, without the proliferation of light, to ensure the efficiency of light.
Q:How much is the price of a LED street lamp?
The price involves many aspects, generally, for main roads around 120W 1100~1300 are normal; for the auxiliary road around 60~80w 500~800 prices are.
Q:LED street lights installed on both sides of the road, horizontal installation and angle installation (0~30 degrees), natural convection heat dissipation, that good heat dissipation.
The angle of heat dissipation is good, because the general hot air will spread upward, and the slope is more convenient for the diffusion of hot gas.
Q:What are the standards for LED street lighting?
Light efficiency, the good light theory is 100lm/W, 100 watt incandescent lamp is about 1200lm, that is to say, about 12W LED lamp luminous flux is equivalent to a 100 watt incandescent lamp, this is the origin of energy saving. Of course, in fact only theory, but also the specific consideration of power loss of LED, loss and attenuation of photothermal divergence, and so on, is not to say, here is not to write.
Q:What are the 6 main disadvantages of LED street lights? What are the 6 major disadvantages?
Light LEDAfter a period of illumination, the light intensity of LED will be lower than that of the original light
Q:Who knows the relationship between the number and weight of LED street lamp
The relationship between the number of LED light weight and beads, the strength of your life,Can not get a formula, a single lamp can be 1W, or 100WThe relation between street light weight and street lamp power can still be obtained, only at presentDie casting space aluminum cooling, about 100W, about 20 pounds
Q:What role does the light controller and driver play in the LED street light component?
At present, the pulse drive chip is powered by a high frequency pulse generator output interface to the LED lamp. Because the pulse signal frequency is very high, so the human eye can not feel the LED strobe, so this method meets the visual needs, and on the one hand, effectively save the power output. Also, the frequency of this type of chip can generally be controlled by an external interface. However, the current frequency of this type of chip is generally in the range of 100KHz~500KHz. So the current drive capability is only suitable for low power applications. However, I believe that in the near future will be elevated to high-power LED driver occasions.
