Q:Solar LED street lamp, how much is a set of solar street lamps wholesale price?

Now the conventional 6 meter 30W power solar energy set price is about 1260 yuan, the detailed price ha needs to calculate according to the lighting time and the rainy days.

Q:What is the display index of the LED lamp?

The degree to which an object's color is rendered is called color rendering. Usually called the color rendering index (Ra)A light source with a Ra value of 100 indicates that the color displayed in the light of the object is consistent with that under the standard light source.For LED lamps, the average color index of the three primary colors is high, and the color index of the blue and yellow phosphors is not as high as the three primary colors of the LED.

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

The system comprises a solar battery component part (including bracket), LED lamp, control box (with controller and battery) and lamp parts; Jin Zhan solar panels light efficiency reached 127Wp/m2, higher efficiency, is favorable for the wind resistant design of the system; the cap portion with 1W white LED and 1W yellow light LED integrated in printing the circuit board is arranged in a certain distance matrix as plane light source.The control box body is made of stainless steel, and the utility model is beautiful and durable, and the maintenance free lead-acid battery and the charging and discharging controller are arranged in the control box. This system chooses the VRLA battery, because of its little maintenance, so it is also called "maintenance free battery", the system is conducive to the maintenance cost is reduced; the charge and discharge controller both functions in the design (with light control, time control, overcharge protection, over discharge protection and reverse protection etc.) and cost control, to achieve a very high price.

Q:22 km road, every 33 meters to install a street lamp, street light power 120W, attached to the LED display 60W, a total of 180W, seeking the best laying line program

611 lights should be divided into at least 10-20 parallel units.

Q:Constraints on LED street lights

The development of the domestic LED light source relative to foreign technology started late, from the international leading industry there is a certain distance, although the domestic LED light source theory of life can reach 100 thousand hours, but because of the heat problem cannot be solved completely and effectively, so that the actual life of large discount; unstable power supply system: LED driver power supply is the industry consensus in fact it is not stable, on the LED lighting industry back, because the driving power supply is an important part of the LED street lamp, which will lead to failure of the whole lamp fault. Due to poor reliability of power installed street lights are likely in a short period of time will be bad, the LED street lamp this outdoor height device, difficult installation, maintenance more difficult, for the lamp manufacturers, power supply instability makes the rising cost of maintenance.

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

Here to analyze the advantages and disadvantages of several light source: high pressure sodium lamp has high efficiency, long life, light penetration, rain and fog irradiation range is relatively secure, but a single color spectrum, low resolution, according to details of poor road.

Q:What is the voltage of the street lamp?

Street lights are directly connected with the city grid, so the street lamp voltage is generally 220V AC, belonging to high output, low energy saving lamps.Street lamps, lamps that provide lighting for the road, generally refer to lamps within the range of road lighting. Street lights can be seen everywhere in our lives, and they are indispensable lighting equipment.

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

But only a few out of the chip package LED lamp has many kinds of companies with different types of beads made products, but now a bunch of polycrystalline with a single tall power generally have finished 12 3W

Q:What are the standards for LED street lighting?

The average illuminance (Eav) = the number of single light flux Phi x lamps (N) by the coefficient of X space (CU) * (K) / maintenance coefficient of floor area (length * width) only need to know is that the parameters of LED, such as the beam angle is 120 degrees.

Q:What are the components of the LED street lamp holder structure?

The surface of the lamp has been treated with UV resistance and corrosion resistance, and the overall lamp meets the IP65 standard. The outer cover can be made of PC tube, and the temperature can be up to 135 degrees.
