PV pumping system is the use of solar modules to solar energy directly into electrical energy, drive motor driven pump device. Mainly divided into submersible pumps photovoltaic pumping and ground pumping photovoltaic pumping (suction stroke, different installation methods); PV pumping system: no fuel consumption, no power grid, almost no need for operation and maintenance, long service life, low average cost, especially for water and electricity shortage areas. Do not need batteries, solar modules directly driven by the pump work.

According to Duan Xiaoyi, director of the Lighting Research Institute of Dongshan Lighting Research Institute, Dongshan Lighting LED panel light bead is produced by Dongshan Lighting's LED packaging technology with industry advantages. Its production standard will be used for higher TV backlights. LED1206 lamp beads are used to produce lighting products. The purpose is to pursue higher light efficiency, more stable performance, better light uniformity and more reliable quality. The color temperature range is adjustable, from warm tones 3000K to cool tones 6500K, divided into 4 standard products (3000K, 4500K, 5700K, 6500K), color rendering index greater than 80, total luminous flux up to 3000LM;
Secondly, the Dongshan lighting panel light adopts ultra-thin design, the thickness is only 55 mm, the mosaic installation, and the integrated ceiling ceiling form a whole, the appearance is bright and the quality is light. Taking 600*600 conventional size as an example, Dongshan Lighting LED panel light is only 1.57 kg, power 35 watts, can replace traditional grille 3*600MM fluorescent lamps more than 85 watts, the number of lamp beads is 168, the energy consumption is only equivalent to traditional fluorescent lamps. 40%; and the product has passed CE certification. At present, from the trial results of some customers of Dongshan Lighting, the market prospect is very good.
Dongshan Lighting expects that the product will be fully booked for the first time at the large-scale investment promotion conference on July 18, and will officially launch the LED lighting market. The product is widely used in offices, hotels, exhibition halls, conference rooms, factories, clubs, commercial shops and homes. It is easy to install, safe and fast. 
Since the launch of Dongshan Lighting's June Thunderstorm investment promotion work, Dongshan Lighting has successively implemented multi-channel and multi-form strong investment promotion activities such as exhibition investment and special investment. In July, Dongshan Lighting's investment theme was positioned as “flat storm, strong attackâ€, and the LED panel light “seeing the light without seeing the light†was launched.
