ALLTOP Lighting's Portable Power Station 1000w

Believe that a lot of friends are all very understanding, in the construction of urbanization, the use of lighting equipment are all direct electric consumption, the electricity to city life has brought the very big burden. And in the waste of resources is not environmental protection at the same time, influence the life of the city, in the solar street light after the situation seems to be a lot better. In outdoor solar street light control box body with stainless steel as the material, attractive and durable; Control box to place free of lead-acid battery and charge and discharge controller, is advantageous to the cost; Charge and discharge controller in the design for the full ( With electric, control, when the overcharge protection, discharge protection and reverse connect protection, etc. ) And cost control, the use of solar energy lighting lamps achieve very high cost performance, its power is great, high, long working hours, life issues are prominent. But also note that the installed solar street light light pole is beautiful. Starting from the foundation construction, the lamp will be subject to the mainline control good linearity, and reasonably according to the road design linear change, light pole straight, processing of weld and repair the mouth to avoid the line direction, and consistent across the board. Light pole cantilever Angle to keep the direction and Angle coordinate. Want to learn more industry information or ask price, can call advisory

zhongshan solar panel manufacturers - — Guangdong energy technology co. , LTD. Sun solar panels are made of semiconductor materials. Its development up to now, a variety of forms. ( 1) According to the structure classification (solar panels, 1) Homogeneous junction solar panels homogeneous junction solar panels is to have one or more of the same semiconductor material formation of p-n junction solar panels. Such as silicon solar panels, such as arsenic and solar panels. ( 2) Heterojunction solar panels heterojunction solar panels by interface made up of two kinds of semiconductor materials with different band gap width of the p-n junction heterojunction solar panels.
the indium tin oxide/silicon solar panels, for example,
copper sulfide/cadmium sulphide solar panels, etc. If two heterogeneous materials of lattice structure similarity and interfacial lattice matching is good, is called the heterogeneous surface solar panels, such as aluminum gallium arsenide/gaas heterogeneous surface solar panels. Solar panels can be divided into the following categories according to different materials. ( 1) Solar panels are made of silicon solar panels, such as monocrystalline silicon solar cells, polycrystalline silicon solar cells, amorphous silicon solar cells, etc. To make polycrystalline silicon solar panels, solar panels can use low purity. Polycrystalline materials include ribbon silicon film, casting silicon, polycrystalline silicon and other. Made of them the solar cell has two kinds: film and sheet.

Solar panels - Guangdong energy technology co. , LTD. , about compound solar batteries are classified as follows: compound solar cell by means of compound semiconductor materials solar battery, the current application of basically has the following kinds. ( 1) Single crystal of compound


- solar panel manufacturers Guangdong energy technology co. , LTD will compound solar cell classification is as follows: the composite solar cell is made of compound semiconductor materials of solar cells. At present, mainly use the following types of solar cells. ( 1) Single crystal compound solar cell composite solar cell is primarily a gallium arsenide single crystal ( GaAs) The solar cell. Energy gap of gallium arsenide is 1.
4 ev is an ideal battery materials. This is the most effective single cells, multi-junction gaas cell conversion efficiency over 40% (
AMO) 。 Because the highest efficiency, applied to outer space at an early age. But gallium arsenide batteries are expensive, and arsenic is a toxic element, so rarely used on the ground. ( 2) Polycrystalline compound polycrystalline composite solar cells there are different types of solar cells. At present, and copper indium gallium selenide cadmium telluride solar cells solar cell has been applied in practice. In addition, there are organic dye sensitized semiconductor solar cells ( Dysi solar cells, etc. ) 。 ) 。 Solar panels are divided into different USES. 1. Empty solar cells empty solar cell is used in satellites and spacecraft, the spacecraft's solar cells. Due to the use of special environment, solar cells with high efficiency, light weight, high low-temperature impact resistance, resistance to strong high-energy particle radiation, such as performance, and fine craftsmanship, is expensive. 2. Ground solar ground solar cells means for solar power generation system of solar cells. This is currently the most widely used solar cells. Wind, frost, rain, snow, has higher electricity price ratio, with the technical feasibility of the mass production and rich source of raw materials.

Generally speaking, the high power LED project-light lamp light Angle smaller, light more far, such as LED project-light lamp garden road lighting Angle of 50 °, general than light Angle is 130 ° project-light lamp as well. Outdoor high-power LED project-light lamp is widely used, in addition to the application in building


in general, high-power light-emitting diodes (leds) have a smaller light Angle projection lamps and lanterns, and the farther the light irradiation, for example, light emitting diode projection lamp light Angle of 50 degrees, this often than light Angle of 130 degree projection lamp light Angle further. Power leds floodlight outdoor applications, not only for architectural lighting, also used for high beam lighting, tunnel lighting, underground lighting, lighting stadium wharf. High lighting ( As shown) , light-emitting diodes (leds) projection lamp with 50 degrees, ensures that light on the ground. Floodlight lighting Angle is 90 °, is mainly used in building lighting, wide range of USES. Tunnel lighting Angle is 130 °. The invention of light emitting diode that shoots the light Angle can be adjusted according to user requirements, and can be used according to the situation to increase power leds for lighting lamp wattage to increase brightness. Ding Han LED floodlight manufacturers and other conscience of formal enterprises can ensure that the product is suitable for high lamp, floodlight, tunnel lighting situation, and ensure adequate lighting projected onto the ground.

LED light source is a semiconductor light source, its own light-emitting characteristics determine its failure rate is quite low, and the failure rate of the connection part is also quite low. The quality of the LED drive power directly determines the life of the entire street lamp, so the power supply has become the LED street lamp industry The core part of it. Generally, LED street lamp power supply is the most efficient switching power supply, up to 95%, power factor up to 0.99; high reliability and long life, in line with IP67 waterproof rating; with overvoltage, overcurrent, overtemperature and short circuit protection, constant current and constant voltage optional, with It has lightning protection design (IE-61000-4-5Class) and complies with global safety regulations and electromagnetic compatibility standards. The LED street lamp power supply requires a certain design margin. The waterproof power supply of the power supply can ensure stable and reliable operation when the input voltage is 176-305VAC, and for some special requirements, there are also many power supplies that can work normally when the input voltage is 90-305VAC.　　The country advocates energy conservation and environmental protection, and the LED street lamp project is currently the representative project of the national energy conservation and emission reduction project. In the light-emitting components, the characteristics of the LED itself have achieved very good energy-saving effects, but the power supply section cannot be ignored. The energy-saving power supply will undoubtedly be the most important part of the street lamp power supply in the future.
