Advantages of LED street light

1, LED street light characteristics, light, no light diffusion, ensure light efficiency;
2, LED street light has a unique optical design of the two, the LED street light irradiation to the desired lighting area, further improve the efficiency of light, in order to achieve the purpose of energy conservation;
3, LED light source efficiency has reached 100lm/W, but there is still much room for development, the theoretical value of 250lm/W. The luminous efficiency of high pressure sodium lamp is only increased with the increase of the power, therefore, the overall optical efficiency of LED lamp is better than high voltage sodium lamp is strong;
4, LED street light color is much higher than that of high pressure sodium lamp, high pressure sodium lamp color index is only about 23, while the LED lamp color index reached more than 75, from the point of view of visual psychology, achieve the same brightness, illumination LED lamp can average 20% lower than high pressure sodium (with reference to the British standard lighting principle);
One
5, LED street light a small decline, a year decline of less than 3%, 10 years still reached the road illumination requirements, and high pressure sodium lamp failure, a year has decreased by more than 30%, therefore, LED lamps used in the design of power can be lower than high pressure sodium lamp;
6, LED street light with automatic control energy saving device, can meet the requirements of lighting in different periods of time to reduce the maximum possible power, save energy;
7, the LED is a low voltage driving device, single LED safe voltage, series of single LED power is 1 watts, so it is safer than the use of high voltage power supply, especially suitable for public places (such as street lighting, industrial lighting, automotive lighting, lighting and other people);
8, each unit LED chip is only a small volume, so it can be prepared into various shapes of the device, and suitable for volatile environment.
9, long life: can use more than 50 thousand hours, provide quality assurance for three years.
10, high light efficiency by more than 100LM above the chip, compared with the traditional high pressure sodium lamp can save 75%.
11, the installation is simple: without buried cable without rectifier, directly to the street lamp installed in the lamp or light source connected to the original nested shell.
12, excellent heat control: summer temperature control at around 45 degrees, and the use of passive cooling mode.
13, the quality is reliable: the circuit power supply all uses the high quality components, each LED has the independent overcurrent protection, does not need to worry about the damage.
14, color uniformity: without lens, not to increase the brightness and uniform light color so as to ensure no sacrifice, iris color uniformity.
According to the above principle, the energy saving effect of high power LED lamp significantly, instead of high pressure sodium lamp can save more than 60%.
Maintenance cost is low: compared with the traditional street lamp, LED street light maintenance costs are very low, after comparison, less than 2 years to recover the full cost of inputs.

LED street light

LED street light is an important part of city lighting, traditional street lamps used high-pressure sodium lamp, the overall light low pressure sodium lamp caused a huge waste of energy, therefore, the development of efficient, energy saving, long life, high color rendering index, environmental protection is very important for city street lamp lighting energy-saving significance.

High power LED street light and high pressure sodium lamp is different from conventional light source, high power LED street light with low voltage DC power supply, by the synthesis of GaN based blue LED and yellow fluorescent powder, white LED, with high efficiency, safety, energy saving, environmental protection, long life, fast response speed, high color rendering index unique advantages and can be widely used in city road lighting.

Light emitting diodes (LightEmittingDiode, abbreviated as LED) is a semiconductor pn junction formed with weak electricity can light high efficiency solid-state light source based on the forward bias voltage and the injected current, injected into the P region of the hole and injected into the N region electron in diffusion into the active region after radiation and emit a photon, electric can be directly converted into light energy.

Street Light Pole

 

Street Light Pole Scope

This Specification covers the design, fabrication, testing and supply of fully galvanized tubular steel poles to be used for solar street lights.

Street Light Pole General

The steel street light pole shall be designed and fabricated to withstand the wind velocity of 160km/hr. with all the necessary supporting load and accessories (Battery, Solar Module etc.).
The steel tubular poles must be manufactured by a company approved to quality standard ISO 9001:2000. The ISO 9001 certification number, the name of the authorized approving authority with the contact address and telephone and fax numbers shall also be stated.

Street Light Pole Description

Street Light Pole

Street Light Pole

The steel street light poles shall be of single tubing design.
The steel tubing used in pole fabrication shall be of steel of any approved process possessing a minimum tensile strength of 42 kg/sq. mm and a chemical composition of not more than 0.06% sulphur and not more than 0.06% phosphorous.
It shall be the responsibility of the supplier to determine the adequacy of the component tubing shown for the load to be sustained.

All tubes forming parts of the above supports shall be made from hot insulated seamless or continuously welded steel in accordance with BS 6323 or equivalent applicable Standards.

The street light poles shall be fully galvanized with minimum coating of weight not less than 460gm/sq. m internally and externally.
Each street light pole shall be provided with a steel top plate 3-mm minimum thickness welded to the end of the section. The top plate shall not project beyond the perimeter of the top section. Each pole shall also be provided with a welded base plate welded to the bottom of the pole.
The size of the base plate shall be as per governing standard and design requirements.

Street light pole Tolerance

The following tolerances shall be maintained:
a) Tolerance of diameter: +/-1%
b) Tolerance on weight: +/-1% on each pole.
c) Tolerance on thickness: +/-1%

Soalr Street Light Pole Tests

The following test(s) shall be performed for the pole furnished.
Number of poles selected for conducting tensile test and chemical analysis for sulphur and phosphorous shall be as given below:
Lot Size No.of poles
Up to 500 1
501 to 1000 2
1001 to 2000 3
2001 to 3000 4
3001 and above 5
Number of street light poles selected or conducting deflection test, permanent set test shall be as given below:

Lot Size No. of poles
Up to 500 5
501 to 1000 8
1001 to 2000 13
2001 to 3000 18
3001 and above 20

The deflection test and permanent set test shall be conducted in succession on each of the poles selected.

Deflection Test

Each street light pole shall be rigidly supported for a distance from the butt end equal to the depth which it is to be planted in the ground. It shall then be loaded as cantilever and the guaranteed deflection load applied at right angles of the axis of pole 60 cm from the top. For convenience in testing, the pole may be fixed horizontally and the load applied vertically. The temporary deflection due to the applied load at the point of application of load shall not exceed 157.5 mm.

Work Requirements

zero position after the release of the appropriate applied load at the point of application of the load shall not exceed 13 mm.

Should of any of the poles selected fail to pass any of the tests specified above two further poles shall be selected for testing from the same lot in respect of each failure. Should both these additional poles fail, the test material represented by the test samples shall be deemed as not complying with these specifications.
