Q:LED street is a single bead or multiball well

You say is the difference between a single tile and integration that it is of course a single well, the integrated cooling is not good, and will affect the light, LED lamp, the same power, the actual flux lamp luminous flux integrated light source is less than a single tile,In one is integrated, as long as there is a chip in the broken, it is not bright, and maintenance costs are high, I hope to adopt

Q:How much solar panels do you need to make a 15W LED solar street lamp?

According to your work time and the continuous rainy days, and then calculate the power: LED * * working time of continuous rainy days = depth of discharge battery (AH) battery discharge depth / sunshine time / silicon solar panel power = charging efficiency

Q:How many watts does the LED street light have?

The technology is mature day by day, and the high-power LED light source can meet the needs of general street lamps. The general optical efficiency of high pressure sodium lamp is 100LM/W, high power LED is commonly used by foreign 50-60LM/W, the best LED chip can reach 80LM/W, the luminous efficiency is high, means that the energy saving effect is better, which is the choice of one of the most important indicators of LED street lamp. However, the LED standard does not specify this, so the purchase of LED street lamps must be carefully confirmed.

Q:What is the problem of flashing LED street lights on the side of the road?

If all the lights of the LED are flashing, it is likely that the supply current and current are not normal

Q:Do 150wled street lights use much?

The problem of heat dissipation of domestic high-power LED street lamp has not been completely solved, and the cost of follow-up maintenance will inevitably increase.

Q:Can the LED power supply be used as street light power supply?

First of all to his high efficiency, high efficiency loss can be reduced, the PF value is higher than 0.96, the rate of loss is greatly reduced and the components, and there shall be 4 in one PWM dimming, dimming, 1~10V dimming, dimming dimming and resistance time

Q:High frequency jet lamp, LED lamp, xenon lamp, which is suitable for street lamps

High pressure sodium lamp light control, high luminous efficiency, long life, high color, the color is very suitable for 4000K~5000K lamps, but a relatively small enterprise effort in developing high performance and stability of the ballast, on the other hand, because of government support for the LED industry, so its application in the street did not get attention and promotion proper.

Q:What ballast does the street lamp use?

Using metal halide ballast, it depends on what kind of light, are now "popular" LED lighting, however, there are two main types of our common street lighting, is a metal halide lamp, the other is a metal halide lamp, the latter is a little better, but the price is more durable some high.

Q:The design idea of LED intelligent energy-saving street lamp

The traditional light sources used for road lighting are mainly high pressure sodium lamps. The LED street lamps are mainly used in some trunk roads, but they have shown obvious difference. In the light effect, high pressure sodium lamp is up to 140lm/W, than the current commercial 100lm/W high power LED light efficiency is high, but the LED color index (about 80) is much more than high pressure sodium (about 25), and in the same illumination, white LED helps the driver or pedestrian recognition target, the road lighting the effect and comfort degree is much higher than that of high pressure sodium lamp. In the lighting efficiency, high pressure sodium lamp designed by considering the spherical reflector efficiency of high pressure sodium lamp efficiency generally only 70%. but LED is a directional light, such as the use of appropriate design of light distribution, most of the light will directly onto the pavement, the lamp efficiency can reach above 85%.

Q:What is the luminous flux of LED30W solar street lamps?

If it is accurate calculation method, we need to go to a professional testing center to test, our products are detected by Shanghai electric light source, and the corresponding test data is satisfactory.
