The application of LED light source in the lighting field of the city

The application of LED light source in the urban landscape lighting is not pursuing brightness, but the art of creative design. LED has strong direction, and can be used for main lighting in local area. Inserted scattering agent in packaging material can achieve a light-emitting angle of 175 degrees and is suitable for great range of illumination. But the problem is the construction of urban landscape lighting unit only focuses on high brightness, which limits the range of options for designers .

Currently the LED light source commonly used in the urban landscape lighting are:

1. linear luminescent lamps

LED linear luminescent lamps (tubes, belts, wall lights, etc.): contour lighting effects they produced can replace the traditional neon, magnesium neon light tube, fluorescent color.

The working voltage for commonly used products is DC12V, 24V (most adopt high-power switching power, while there are some products using linear power), AC220V; control mode is divided into internal and external control, and in lighting engineering, people generally use tens to hundreds of single body composition.

LED linear luminescent lamps have the characteristic of excellent weather resistance, low light attenuation, varied colors, and mobile changing lighting effects, thus they have been widely used in urban architecture lighting .

To sketch the outline of a building lamp, for example, using the principle of red, green, and blue color combination of LED light source, it can be varied under microprocessor control in different modes, such as the water ripples continuous color, timed color, gradient varied color, transient color, resulting in the mix lighting effect for the tall buildings at night .

2, decorative lawn lamp, landscape, Bulb

Along the streets and green spaces in cities, the glowing ring parts are designed into various structures, like ribbon and banding, to illuminate the green spaces; in daytime it can also become decorative elements for the environment. The common working voltage is AC220V, mostly for internal control (it can be synchronized with synchronized cable if synchronized changes are needed).

Often the practical project it is used for decorative lighting with gas-discharge light source , it can also achieve colorful lights phantom with the combination of various functional and structured LED light source.

This "multi-color, multi-highlights, muti-patterns " changes, embodies the characteristics of LED light source.

3, underwater lights

LED underwater lights are placed under water, used for lighting in the water, and its protection level should reach IP68 and rated working voltage is DC12V.

LED low-voltage operating characteristics make it be safer than any conventional lamps, its long life advantages also make maintenance more convenient, and the lighting effect is also better than conventional PAR lamps, gas discharge lamps.

4, ground lighting: Buried lights, light brick, stone lamps, etc.

Using LED light source for ground lamps can be miniaturized in size. On the one hand it can be used as ambient lighting, on the other hand it can be used as light-emitting decorative lighting or directing lighting.

Depending on the particular structure of the floor covering, the area of lamp’s light outlet varies. Embedded stone lights, brick lights agree with paving stone in the way of trimming, to achieve harmony and unity between the environment and the light source .
