Solar LED street lamp system windshield

In the solar LED street lamp system, the problem that needs very much attention to the structure is the wind design. The wind is mainly divided into two major blocks, one for the windshield of the battery assembly bracket, and the second is the windshield of the light lever. The following is analyzed in the above two pieces.

(1) Solar LED street light solar battery assembly bracket windshield

According to the technical parameters of the solar LED street lamp manufacturers, the solar cell module can withstand to 2700Pa. If the wind is selected to be 27m / s (equivalent to ten typhoon), depending on the non-stick fluid mechanics, the battery pack is only 365Pa. Therefore, the component itself can completely withstand the wind speed of 27 m / s and not damaged. Therefore, the key to the design is to consider the connection of the battery pack bracket and the solar LED street light pole.

The connection design of the battery component bracket and the solar lamp pole is fixedly connected using a bolt bar.

(2) Solar LED street lamp pole windshield

The parameters of the solar LED street light are as follows: Battery board inclination A = 16o light pole height = 5M design selection Solar LED streetlight lever bottom weld widthδ= 4mm solar LED street light pole bottom outer diameter = 168mm

The weld is on the surface of the lamp to destroy the surface. Solar LED Street Light Bar Destructive Finding Torque W Calculation Point P to the Battery Board Fidel Mount F Wide Board F Wide PQ = [5000 (168 6) / TAN16O]×SIN16O = 1545mm = 1.545m. Therefore, the role of the wind load in the sneakers of the solar LED street light pole M = f×1.545.

The maximum allowable wind speed according to the design of 27M / s, 2×The basic load of the 30W double-lamp head solar LED street lamp is 730N. Consider 1.3 safety factor, f = 1.3×730 = 949n. So M = f×1.545 = 949×1.545 = 1466N.m. Depending on the derivation of mathematics, the resistance of the circular designs surface W =π×(3R2δ 3Rδ2δ3). In the above formula, R is the inner diameter of the ring,δIt is a ring width. Destructive surface resistance W =π×(3R2δ 3Rδ2δ3) =π×(3×842×4 3×84×42 43) = 88768mm3 = 88.768×10-6 m3 The stress caused by the moment of wind load in the destructive surface = m / w = 1466 / (88.768×10-6) = 16.5×106PA = 16.5 MPA

Anti-theft design of solar LED street lamp system

It should also pay attention to anti-theft work, many times, because of the negligence of construction, there is no effective anti-theft, leading to the solar LED street light storage battery, solar LED street light battery board, but not only affects normal lighting, but also caused Unnecessary property losses. At present, it is a potent anti-theft measures in the current engineering case, solar LED stream battery, solar LED street light storage is a effective anti-theft measures. Theft of the battery board is mainly due to the low or climb around the solar LED street light pole, so the height of the solar LED street light pole is preferably 5m or more.

Waterproof design of solar LED street lamp system

The waterproof of the solar LED street light controller, most of the controller is installed in the lampshade, and the solar LED street light storage box is generally not invested. However, in the actual engineering case, some because of improper installation, will follow the controller terminal due to rainwater Wiring flow into the controller causes short circuit. Therefore, it should be noted when the controller terminal internal cable is bent into a U-shaped and solid, exposed to the external cable is also fixed as a U-shaped, so that the rain can not be short-circuited, and can be inside and outside. Waterproof glue is applied at the line interface to waterproof.

　　Author ：Green earth– LED Strip Lights manufacturersAs far as the LED tube we have seen, there is a structural, internal wiring, anti-electric shock protection, insulation resistance, and electrical strength, creepage distance and electrical gap, heat resistance and refractory. Different LED tubes are different from the light source and materials that determine different price and safety, and the LED tube has a built-in power supply, and the agency different decisions is different.Century Ruiguang Company Engineering Department Li Manager's current technical security issues related to LED tubes, for the type II anti-electric shock type, requires LED tube input contact to reinforce insulation resistance and electrical strength, many built-in power transformers and LED module aluminum substrate Improper installation, causing the test to pass. Or many companies use non-separated power supplies in order to save costs and power efficiency. Internal wiring is mainly linear and insulating thickness, mechanical damage, and insulating layer. The inside is basically can't be in contact with the lamp shell of the aluminum, and the insulation is enhanced. It is also necessary to avoid internal wires and power supply directly to contact the outer casing and prevent the wire from being broken. In terms of structure, it is necessary to prevent insulation of the lamp head, screw, and contact metal surface, and the corresponding lamp head plastic should be used to prevent melting. Since the screws of the LED tube are directly locked, they are required to pay attention to the creepage distance and electrical interval. The internal power supply and the aluminum housing are needed to be separated from the insulating sleeve to reach the power level. The lamp holder and the lamp body are relatively insulated to prevent leakage of the shell.Article Source: LED tube

Question About LED Street Lamp Cooling Mode

　　Author ：Green earth– LED Strip Lights manufacturersNow LED lighting technology is increasingly mature, but the LED street base is on the heat transfer or heat dissipation problem, what we can take is still limited, so today Xiaobian should talk about the problem of choice for LED street lamp heat dissipation mode, hoping Help everyone.At present, the heat dissipation of the LED street base is mainly divided into natural convection heat, adding fan forced heat dissipation, heat pipe and circuit heat pipe heat dissipation, and the installation fan forced heat dissipation mode is relatively complicated and the reliability is relatively low, and heat pipe and circuit heat pipe heat The cost of the way is compared, and because the LED street lamp is often used outdoors, the heat dissipation surface is located on the side and the body type is limited, and these factors are too friendly for other two ways, but However, it is necessary to play air naturally, the advantages of the flow of the heat dissipation, so the LED streetlights should choose natural convection heat when selecting a heat dissipation method.

How Much Do You Know About the LED Street Lamp? @Led Street Lamp

　　Author ：Green earth– LED Strip Lights manufacturersThe traditional LED street lamp design is paying attention to the number of LEDs, and it is not much for its heat dissipation effect, in fact, it is not right. In life, with the increase in the number of LEDs, the heat dissipation design is also required, and the traditional heat transfer means is conducted, convection, Radiation and phase change heat, so we have to solve problems on the issue.LED street lamp heat dissipation technology uses a heat-insulating board mode, because the copper plate is relatively thick, so it is not very convenient to use, and there is still a risk of dangerousness, if you encounter a typhoon, or the earthquake may be an uneasy factor, so now It is a needle heat dissipation technology.Such a technique makes the heat dissipation, so that the LED junction is lower than the ordinary heat sink at least 15 C, and has good waterproof performance, there is basically no uneasiness due to weight, so Xiao Bian also likes this. The lamp is easy to install.The heat dissipation method of the lamp holder can be divided into a variety of forms, heat pipes, circuit heat pipe heat dissipation, installed fan forced heat dissipation, natural convection heat, etc. Low, so smallIt is recommended to use natural convective heat to reduce, safe and low cost.
