  • Principles
  • Standards and Applications

  • 1.low power consumption, long working life characteristics.

     

    The low power consumption of LED lighting will not only reduce the lighting energy consumption, but also reduce the cross-sectional area of power supply cables because of the reduction of energy consumption, which can also reduce the investment in cables during the construction process. Long working life can reduce the expenditure of maintenance costs during use.

  • The port light need to has impact resistance characteristics.

     

    Bridge crane trolley is usually installed on 4 high-pressure sodium lamp, in the process of use, the trolley frequently pass through the front beam stranding point, making the beam short rails appear loose and uneven, etc., resulting in the trolley driving process vibration, inevitably bring impact, making the internal lamp, wire and other devices loose, affecting the use of lamps, serious will also make the lamp shell cracking or even fall, similar problems also appear in the rail The use of crane lighting fixtures. If you use LED lighting fixtures, will effectively avoid this situation, a port on the LED lighting fixtures to replace the 2 bridge crane car on the high-pressure sodium lamp, after nearly a year of use, the effect is remarkable.

  • 3.Fast response time feature.

     

    In the process of energy-saving renovation in ports, some ports group the front beam floodlights of bridge cranes into different gears according to the ship type, and the driver can choose to turn on and off independently; some ports, on the basis of grouping the front beam floodlights, use the existing trolley encoder to judge the working position of the trolley, and then the PLC will automatically judge the grouping and choose to turn on and off the floodlights automatically after a period of delay. However, since the current large-scale use of high-pressure sodium lamps, there is a slow start, and the frequent start of the floodlights will easily lead to insufficient lighting and shorten the service life of the floodlights. If you use LED lighting fixtures, using the characteristics of LED fast response time, will effectively solve the above problems, while greatly improving the energy-saving effect.

  • 4.Easy to dimming, controllable large characteristics.

     

    Easy dimming, controllability is another major feature of LED lighting, through the application of dimming technology, will further reduce energy consumption, saving electricity for lighting, reduce output power, but also will improve the working temperature of LED lamps, extend the life of the lamps, improve reliability. At present, there are already LED street lights with dimming interface.

  • The lighting standards for marinas will vary for different uses, and only the general area lighting standards are given below.

    The wharf is located along the river and ocean, the air humidity is relatively high, and the salt spray and marine climate erosion is serious. Especially near the southeast coastal region of China, there are more typhoons and rainstorms, and the climate conditions are harsh. At the same time, in the terminals with conveying bulk goods (coal or grain), there is the proliferation of fine particles, which can cause serious dust pollution, and these are the factors that need to be considered when carrying out lighting design. The lamps and lanterns used in the dock should meet the following requirements.

    1. protection level not less than IP66.

    2. the anti-corrosion level of the luminaire needs to meet the standard of WF2.

    3. Light sources and accessories are easy to replace.

    4. good anti-corrosion performance of luminaire parts.

    5. stable installation of lamps and lanterns, with good wind resistance.

    6. Unless otherwise specified by the owner, the luminaires shall comply with the latest national standards (GB) and International Electrotechnical Commission (IEC) standards and International System of Units (SI) standards.

II The way to lay lights

(1) the choice of color temperature

Port lighting traditional lighting color for the low color temperature of about 2 000 K yellow lighting, LED light color temperature is generally 3 000 ~ 6 000 K, after the trial installation of 5 000 K color temperature light, the terminal operators are very uncomfortable, and then adjusted to 3 000 K, operators in practice, or feel a little white, not as comfortable as the previous high-pressure sodium light, therefore, in the trial installation of products LED light source By increasing the proportion of rare-earth orange phosphor and red phosphor, the color temperature of the LED lamps was realized in the range of 2 300 ~ 2 500 K.

(A) outdoor soccer field

(2) Selection of color rendering inde

The color rendering index (Ra) of traditional high-pressure sodium lamps for outdoor lighting is about 20, and the selection of LED lamps is about 40 to 70, which makes the operators feel that they can see objects more clearly at night.

(3) the choice of spectral range

As we all know, the sunlight for natural lighting, 380 ~ 780 nm visible light for the full spectrum of lighting light, in the LED light source package, the choice of yellow YaG powder plus blue light chip light-emitting at the same time, adding rare earth orange powder and rare earth red powder to complement the full white LED spectrum, so that the main wave of LED light between 580 ~ 586 nanometers, looks very close to the quality of light color sunlight at dusk, so that Operators work under this light for a long time, not easy to produce visual fatigue, more conducive to safe work.

(4) the choice of light color coordinates

After repeated experiments to test the contrast, the light color coordinates selected in 2300 ~ 2500 K corresponding to the warm white light around the black body trajectory, the light color is more natural, see objects more clearly, the human eye does not feel uncomfortable.

(5) the choice of brightness

Against the lighting requirements of the port terminal, in the modification and demonstration of LED lighting, the brightness generally increased by about 20 ~ 50%.

 

(6) the choice of illumination

For the port terminal lighting illumination value, the selection of alternative principles is to achieve energy-saving purposes at the same time, the site illumination value to reach and exceed the original high-pressure sodium lamp illumination value, and to be higher than the relevant industry standards more than 30%. After the modification of this project, the test data has been verified that the illuminance has improved in full compliance with industry standard values.

 

(7) The choice of brightness uniformity

Through a reasonable light distribution design, the brightness uniformity of the high-pole lighting and port lighting are controlled within the range of 0.5 ~ 0.9, fully meeting and exceeding the requirements of industry standards.

 

(8) The choice of environment ratio

Through the reasonable light distribution and luminous flux distribution of LED luminaire lens, always keep the illuminance value within 10 m around the lighting workplace in the workplace illuminance value of 0.5 ~ 0.8 range, so that operators and drivers and passengers, not only can see the objects on the work surface, but also see the surrounding environment, increasing the safety of work.
