Jiangxi Province in the industry landscape project to install Ltd., founded in 1994. For 20 years, the industry, adhering to the "Albert Hing China, a human light" corporate mission which landscape design company, to create the industry's well-known "in the industry" brand. In today has grown into a company with many years in the landscape lighting project design, budgeting, construction site management, installation, LED electronic products R & D, manufacturing and sales of high-tech enterprises. Companies with urban and road lighting engineering contractor qualification, special lighting engineering design B qualification, intelligent building three qualifications. LED light-emitting diode is forward electrical characteristics of the LED state when the voltage reaches its luminous, LED begins to glow, landscape design fees continue to increase the voltage, LED light brightness increased dramatically, as then slightly increase the voltage, LED may be instantly burned, shows, LED belongs to a current device, it is this characteristic that determines the LED must work in order to secure a constant current state, which is the other major aspects of LED devices and inconsistent sources, but also in the use of safe use The key factor LED requires full attention of the designer points. Figure One is the power of 1W LED chip forward drive current and the output brightness relationship, can be seen, lumen output drive current and showed significant linear relationship in the 350mA range. However, with increasing forward current, gradually appear non-linear relationship between the two. When the drive current exceeds the linear range of urban landscape design, produce lumens per watt efficiency will be reduced, but within the linear range of landscape design, the number of lumens per watt produced will show an upward trend. When the driving current exceeds the linear range of the power converter will cause the output from the LED to the form of heat, this heat can be a burden to the LED driver, designed to increase the complexity of the heat and reduces the LED life. So for 1W power LED devices, the forward drive current does not exceed 350mA. Ф5 currently used for small power LED lamp beads, forward current not exceeding 20mA. For 3W high power LED chip, forward current should not exceed 700mA. Jiangxi Province in the industry landscape project to install landscape lighting Engineering Limited is engaged in the design, budgeting, construction site management, installation, LED electronic products R & D, manufacturing and sales of high-tech enterprises. Companies with urban and road lighting engineering contractor qualification, special lighting engineering design B qualification, intelligent building three qualifications. Interior design is a professional lighting design for a variety of architectural illumination environment, color temperature, color rendering index performed. It is not only to meet the requirements of the room, "Brightness", but also play a contrast setting, the role of the atmosphere. General requested by the interior architect, electrical engineer accounting adjustment. Also refers to actions to illuminate the lights or lamps to illuminate the state. Landscape design] [Nanchang, landscape design company which, in the sector of road lighting design lighting provided by China industry.
