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, 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 energy saving lamps to identify the pros and cons of a packaging and trademarks mandatory national manufacturer of LED lighting products in the packaging indicated the following: the rated voltage, voltage range, rated power, rated frequency. In general, good quality products, label printing quality, legible, easy to fall off, wipe with a soft damp cloth, signs legible and indelible, there are manufacturers of trademarks and related certification mark. Poor print quality and shoddy products, fuzzy fonts, easy to erase lighting design, no manufacturer's trademarks and related certification mark. Second, LED lamp LED energy-saving lamps look real, with tricolor pipe, white, hands over look whiter. Also, speaking from the lamp, the lamp can put more than just put them together, lamps good consistency of shapes and sizes, mostly bending molding machines, mostly mass-produced products. Consistency of the product is good, the quality is easier to be guaranteed, the interchangeability of better maintenance. Of course, building lighting design quote, it can not have cracks between loose and interfaces are prized appearance. During the installation, the demolition process, there should be no loose cap, head tilt phenomenon. Lights must choose the kind of engineering plastics flame retardant plastic case type. Ordinary plastic deformation and flammable, is prohibited for the production of energy-saving lamps. Can be simply determined from the surface of both, the latter surface is smooth, shiny, like frosted glass former surface texture.

Companies with urban and road lighting engineering contractor qualification, special lighting engineering design B qualification, intelligent building three qualifications. Adjustable LED light, there are two main methods. One is to change the constant current, the one is to change the pulse modulation. LED is a light emitting recombination of electrons and holes, the beam depends on the current. The current is small, and the beam current is substantially proportional to the design of road lighting, residential lighting when the LED current increases design costs, the heat increases, cause the light emitting efficiency becomes low, and the current is not proportional to the beam. In changing the pulse duty cycle method, the Talbot-Plateau effect (after receiving repeated instant flash, the average brightness of the human eye will feel the repeated time), you can change the brightness according to the pulse duty cycle. Optical properties compared with incandescent and fluorescent light emitted by an LED is relatively small, so the need to use multiple pieces of LED. Meanwhile, the LED light emitting area, high brightness, the human eye look, then it is easy to vertigo. To reduce the brightness, to use a diffuser plate. However, a diffusion plate, in the diverging light in all directions, reducing the efficiency of light. LED, incandescent lamp, fluorescent lamp light distribution varies. The so-called light distribution means and the direction of light emission intensity in each direction. Even with the same light source, if different light distribution, the illuminance distribution will be different. Sometimes the situation would have wanted to reduce the exposure of local illumination, and the rest but increased illumination will appear. Nanchang lighting design, lighting design in the industry, tunnel ventilation network, building lighting design quotes provided by China lighting industry.
