Optoelectronics Technology Co., Ltd. Nanchang Ou main products are: solar lights, solar garden lights, solar lawn lights, solar wind hybrid street light series; a variety of LED light sources, solar PV modules, batteries, controller; various lampposts, patio poles, waterproof box and supporting the use of flip-flops, light control when the control switch and other electrical products. Solar lighting products are green, safe, energy-saving features. Winter solar street concrete attention to the problem of concrete construction in winter winter construction project should be organized well in advance planning and preparation should be taken to prevent snow, frost and other measures for the materials and facilities in advance. During the winter when solar garden construction, the use of Portland cement or Portland cement concrete compressive strength of the preparation to reach 40% of the design strength of not less than 5 MPa and in Hangzhou, not cold. Winter construction, fire prevention should be developed, antifreeze, anti-gas poisoning and other security measures. When pouring concrete mixed with lead gas agents, air entraining admixtures of water reducing agent led solar garden lights to enhance Hang frozen concrete. The temperature of the material mixing concrete shall meet concrete mixture was stirred synthesize the desired temperature. When winter mixed concrete, aggregates may not have snow and freezing clumps, strict control of concrete mix and slump; feeding should be preceded by hot water mixer, feeding sequence: first, aggregate and water and stir in the Canadian cement stirring time stirring at room temperature should be higher than 50% extension of time the machine concrete mixture temperature should not be lower than l0 ℃, into the mold at a temperature not lower than 5'C solar garden villas, transportation and pouring concrete technical requirements: concrete transport time should be as short as possible, container transport concrete insulation measures should be. Template should be removed before pouring concrete, reinforced snow or dirt on the integration of solar garden lights, ready molding curing temperature heat storage method shall not be less than the lot; steam method of not less than 50C; thin structure of not less than 8C Nanchang Europe can Optoelectronics Technology Co., Ltd. The main products are: solar lights, solar garden lights, solar lawn lights, solar wind hybrid street light series; a variety of LED light sources, solar PV modules, batteries, controller; various lampposts, garden lights rod, waterproof box and supporting the use of triggers, light control when the control switch and other electrical products. Solar lighting products are green, safe, energy-saving features. How to charge the battery charging solar street lighting is an important means to be sustainable battery work, but also independent photovoltaic power generation system to be a prerequisite for continued work. Charging equipment and charging technology is an important technical foundation to do the charging work. The traditional way of charging can be divided into constant current charging, constant voltage charging and other improved. Common constant voltage mode where I will not say more, I want to introduce here is an intelligent charging. This charging method refers to automatic tracking dynamically acceptable battery charging current, the charging current and the battery current is consistent internal polarization, also called the minimum loss charge mode. In conventional charging technology, you can not track the size of the actual dynamic state of the battery charge current and acceptable. Intelligent charging system consists of solar battery charge controller and is composed of the dual closed loop, solar charge controller determines the parameters of the battery state of charge current from beginning to end in the vicinity of the battery charging current acceptable curve, so that the battery is almost no gas in the precipitation conditions charging, so that not only saves electricity but no damage to the battery, the implementation of the charging of the battery to accept the need to know the charging current curve. Intelligent charging is the development direction of photovoltaic systems in charging technology. Solar garden lights manufacturers, wholesale solar garden Ou, Harvest solar garden can be provided by the European Optoelectronics Technology Co., Ltd. Nanchang.
