Q:Energy saving control of street lamps can save energy?

Single lamp installed variable power ballast: this measure is to install a power ballast can transform in each high pressure sodium lamp, with the same, at 12 o'clock in the morning, on the road almost no vehicles and pedestrians in the low traffic roads still maintain a high intensity apparently is not necessary. But some roads are not suitable for the implementation of the night lights lit, then can use the variable power ballast, low in road traffic flow, appropriate to reduce the power of the bulb, the bulb 50% to 60% at rated power, when the lamp power while reducing from 40% to 50%, but the road illumination only reduced 30%. Can guarantee the road traffic safety requirements. But even in the midnight voltage increases when the overload phenomenon does not appear light bulb and ballast, which not only can save a lot of power, but also can prolong the service life of the bulb and ballast lamp, which saves a lot of maintenance costs.

Q:What are the features of LED street lamp products?

The utility model has the advantages of small size, low power consumption and obvious power saving effect;High efficiency, shock resistance and mass production conditions;High reliability, environmental protection, non-toxic, no pollution, safety, power saving can indirectly reduce the emission of CO2;Compared with the metal halide lamp, it does not contain mercury and does not emit ultraviolet light;

Q:How is the minimum illuminance of LED street lights Emin obtained? How to calculate?

If you want to measure the value, I can only say that the approximate, because the illuminance value on a point value, the actual measurement is the target area is divided into small areas of uniform, center to measure each region with the value of the measured value, there is a minimum value.

Q:What's the difference between a solar street lamp and a street light complementary street lamp?

Solar street lamp uses solar energy during the day, charging at night, without complicated and expensive pipeline laying, adjustable lighting layout, safety and energy saving and no pollution, without manual operation is stable and reliable, saving electricity and maintenance free.

Q:Is the street lamp good with LED or solar energy?

The LED lamp is compared with the traditional kind of dim lamp is concerned, its high photoelectric conversion efficiency, as we are not the reason of incandescent lamp, because it is the most power is transformed into heat, and then converted into light energy, is a waste of energy. The new LED lights will directly convert electricity to light energy, which is also more energy saving.

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.

Generally speaking, this is a better angle installation, and the light source installed vertically below is the best,In fluid mechanics, the density of hot air is smaller than that of cold air, small density, light mass of hot air rises, cold air sinks, and natural convection occurs. But it doesn't have to be angled, depending on the shape of your fin design and the way it is cooled.

Q:The same brand of chips, how to judge the quality of LED lights?

Pay attention to the LED chips used in LED street lights. LED chip is the core part of LED street lamp, and the quality of LED chip affects the service life, brightness, light color of LED street lamp, etc.. The general import LED chip slightly better quality (such as Puri and CREE) as a municipal engineering, personal recommendations in addition to the two kinds of chips are not other, Liaoyuan century products outdoor Puri CREE, indoor use of wafer,

Q:What is the function of the microcontroller on the LED street lamp?

In the LED street lighting scheme, the microcontroller should be used to tune the PWM input, or FM

Q:LED lamp of common sense, several, such as the LED street lamp, there are many W have many stars, some lamp is a lamp there are a lot of W number

Are you saying that a lamp with LED lamp or with a large number of W! This is not to say the street is not very high if you don't need very bright I think might use 1W 3W this kind of W is relatively smaller number of beads will power many dozens of W a integrated product although the flux is large but his heat is very large if you can not solve it scattered don't consider those.... But if your technology is mature and fairly good, you can use it to integrate power
