What Is LED Street Light – The Define Of LED Street Light

---

Street lamps refer to lamps that provide lighting functions for roads, and generally refer to lamps within the scope of road lighting in traffic lighting. Street lamps are widely used in various places where lighting is required.

Street lights involve lighting technology and are suitable for street lights. The purpose is to design a high-efficiency electronic energy-saving street lamp with long life, low power consumption, high power factor and small current harmonic content. The high-efficiency electronic energy-saving street lamp includes grid high-voltage drain branches R1, C1 connected in sequence, rectifier bridges D1-D4, power factor correction branches C2, D5, D6, medium and high frequency burr filter branches L1, L3, high-frequency oscillation circuit BG1-BG2, start branch L2, C7 and lamp T; save electricity by 80% compared to the previous street lamps; harmonic content THD < 25%, prolong lamp life up to 3-4 times.

Our LED Street Light Price And Efficiency

As an expert in this field, there are many technologies (lamp, reflector, ballast and power switch) that can greatly improve street lighting efficiency. It is important to get all of these aspects correct in order to achieve maximum efficiency.

The right lens can increase lighting levels substantially without increasing the energy consumption (or reduce energy consumption substantially without reducing the lighting level). A well installed fitting, where lamp and gear compartments are tightly sealed, effectively prevents corrosion, dirt and depreciation of the lamp or ignition devices. Greater efficacy (greater lumens of light output per watt of power input) of LEDs and more uniform lighting distribution will surely save energy. From case studies and research, our LEDs can reduce energy consumption from 29-63%. The long life of LED luminaires will also reduce re-lamping costs.

Attempts at artificial lighting on city streets began in the early 15th century. In 1417, in order to brighten up London’s dark winter nights, the Mayor of London, Henry Barton, issued an order requiring lamps to be hung outdoors. Later, his initiative was supported by the French. At the beginning of the 16th century, lighting fixtures had to be installed outside the windows of Parisian houses facing the street. At the time of Louis XIV, many street lamps appeared on the streets of Paris. In 1667, Louis XIV, known as the “Sun King”, also officially promulgated the decree of urban road lighting. According to legend, it was because of the promulgation of this decree that the reign of Louis XIV was called the “Bright Age” in French history.

Street lights are usually classified according to the shape of the light they emit. For the specific division method, the International Commission on Illumination (CIE) recommends that it be carried out according to the three contents of projection, expansion and control.

1. Projection. Indicates the degree of diffusion of the light emitted by the lamp along the longitudinal direction of the road, and is divided into three types: short, medium and long.
2. Expansion. Indicates the degree of diffusion of the light emitted by the lamp in the lateral direction of the road, and is divided into three types: narrow, general and wide.
3. Control. Indicates the degree to which the lamp controls glare, and is divided into three types: limited, moderate, and strict.
4. The installation methods of street lamps include bracket type, overhead type, straight rod type, suspension type and suction wall type.

The Standard Of LED Street Light

The Height Of Street Light

The height determines the field of view, so choosing a good height determines the lighting field of view of the street lamp.

1. The installation height of lamps and lanterns, the installation height of the same street lamps must be the same (the height of the light-emitting center to the ground). Small curved light One meter light 5-6 meters Ordinary street long arm lights and chandeliers 6.5-7.5 meters Fast lane arc lights not less than 8 meters Slow lane arc lights not less than 6.5 meters
2. The special lamp type is installed according to the design requirements. The height of the lamp is roughly equivalent to the width of the road to be illuminated. When only lighting on one side H≌L When lighting on both sides H≌L/2 Wherein, H: Lamp installation height (m) L: Road width (m)

The Lamp Elevation Angle Of LED Street Lamps

1. The elevation angle of the lamp is determined by the street width and the light distribution curve of the lamp, and the elevation angle of each street should be the same.
2. When the lamp head is adjustable, the center line of the light source should fall within the range of L/3-1/2 of the road width.
3. After the lamp body of the long arm lamp (or arm lamp) is installed, the lamp head side should be raised 100mm higher than the pole side.
