Basic introduction to editing Solar Street Light Solar Street Light is powered using crystalline silicon solar cells, maintenance free VRLA batteries (gel batteries) to store electrical energy, super bright LED light solar road lamp as a light source, controlled by intelligent charge controller, used to replace traditional street lighting utility power. Without laying cables, no AC power supply, no electricity; DC power supply, control; with good stability, long life, high luminous efficiency, easy installation and maintenance, security, high performance, energy saving, economical and practical advantages. It can be widely used in urban primary and secondary roads, residential, factories, tourist attractions, car parks and other places. Product Part pole structure: steel pole and bracket, surface spray, solar panels connected by special anti-theft screws. 2 solar street lighting system composed of editors (15) solar street lighting system can protect the rainy weather to work more than 15 days! Its system components are (with driver) from the LED light source, solar panels, batteries (including battery incubator), solar street light controller, streetlight poles (including infrastructure) grade wire and other materials several parts. Monocrystalline solar modules generally used or polycrystalline solar modules; LED lamp is generally used in high-power LED light source; controllers are typically placed in the pole, with light control, time control, overcharge and over-discharge protection and reverse polarity protection, and more advanced lighting controllers also have the seasonal adjustment time function, half-power, intelligent charge and discharge functions; battery is generally placed in the ground or the battery will have a special incubator, can be VRLA batteries, gel batteries, Fe-Al batteries or lithium batteries. Automatic solar lamps work, without trenching wiring, but the poles need device embedded parts (concrete base) on. LED light source 1. High luminous efficiency, low power consumption, long life, low operating temperature. 2. Safety reliability. 3. fast response unit small, green. 4. Under the same brightness, power consumption is one-tenth of incandescent, fluorescent one-third, while life expectancy is 50 times that of incandescent, fluorescent lamp 20 times, after following the incandescent, fluorescent, gas discharge lamps The fourth generation of lighting products. 5. A single high-power ultra-bright LED advent of LED applications across the high efficiency lighting market as possible, will be one of humanity following the Edison incandescent greatest invention. Battery pack bracket 1) Inclination designed to make solar modules in the year received solar radiation as much as possible, we want to choose a best angle for solar modules. Explore the solar modules best angle on the problem, the number of academic publications to appear in a lot. The street light use areas in Changsha, the selected solar modules bracket inclination 16 °. 2) wind solar street lighting system design, the structure of a need to be very important issue is wind-resistant design. Wind-resistant design is divided into two blocks, one for battery assembly bracket wind-resistant design, two designs for the poles of the wind. The following analyzes were done by the above two. ⑴ wind solar modules stent design basis battery components manufacturers technical parameters, solar modules can withstand wind pressure of 2700Pa. If the wind factor selected to 27m / s (equivalent to ten typhoons), according to the non-sticky fluid mechanics, battery components to withstand wind pressure only 365Pa. Therefore, the component itself is completely withstand 27m / s wind speed and not damaged. Therefore, the design of key components to consider is the battery bracket and pole connections. In designing this set of street lighting system in connection with the design of the poles of the battery assembly bracket bolts connecting rod fixed. ⑵ design parameters wind street lights poles are as follows: A = 16o inclination panels pole height = 5m Select the bottom pole design weld width δ = 4mm bottom outer diameter = 168mm poles where the weld surface damage that pole surface. Pole failure surface resistance moment W of P calculation points to the role of the poles by the solar panels line of action of the load F distance PQ = [5000+ (168 + 6) / tan16o] × Sin16o = 1545mm = 1.545m. Therefore, the wind load on the role of surface damage poles moment M = F × 1.545. According to 27m / s design maximum allowable wind speed, solar street lamp double basic load of 2 × 30W solar panels to 730N. Consider the safety factor of 1.3, F = 1.3 × 730 = 949N. Therefore, M = F × 1.545 = 949 × 1.545 = 1466N.m. According to the mathematical derivation, circular failure surface resistance moment W = π × (3r2δ + 3rδ2 + δ3). In the above formula, r is the inner diameter of the ring, δ is the ring width. Failure surface resistance moment W = π × (3r2δ + 3rδ2 + δ3) = π × (3 × 842 × 4 + 3 × 84 × 42 + 43) = 88768mm3 = 88.768 × 10-6 m3 wind load moments role in the destruction of the surface caused by stress = M / W = 1466 / (88.768 × 10-6) = 16.5 × 106pa = 16.5 Mpa << 215Mpa which, 215 Mpa is bending strength of Q235. Therefore, the design of the selected weld width to meet the requirements, as long as the welding quality can be guaranteed, the poles of the wind is not a problem. The main role of the controller solar charge controller is to protect the battery. Basic functions must have overcharge protection, over-discharge protection, light control, time control, anti-reverse, trickle charging protection, undervoltage protection, waterproof protection. Battery anti-overcharge, over-discharge protection voltage general parameters in Table 1) devices use in the selection of the device, there are single-chip, but also the use of comparators, the program more, have their own characteristics and advantages, should be based on the needs of the customer base Features selected corresponding programs, not elaborate on this. 2) Surface treatment of the new series of products using electrostatic painting techniques to paint FP professional building materials mainly to meet the customer's surface color and coordinated environmental requirements, while products with high self-cleaning, corrosion resistance, anti-aging suitable for any climate. Based on the painting process for hot-dip zinc design, product performance is greatly improved, meet the most stringent requirements AAMA2605.2005, and other indicators have reached or exceeded the requirements of GB. 3) trickle charging protection -kai solar panels for battery charging, the battery voltage after reaching the peak, if it continues to charge high pressure water loss or likely to cause the battery out of control; when you stop charging the battery and can not be saturated. This section in the charge-to-peak voltage of the controller down immediately after 1V, then enter the trickle charge state, to ensure that the battery can be stabilized in the full state, while avoiding the loss or loss of control, similar to the battery charge cycle is not only efficient protection of the battery, but also to enhance the battery charge cycles, longer life.
