How to choose suitable LED power supply for led display?

led Power supply is playing an important role to the quality of a led display, but how to choose suitable power supply for led display? The answer is on www.optokingdom.com.

Three points for selecting power supply:

1. Application environment conditions: temperature, humidity, sand and dust, installation method.

2. Electrical application condition: lightning protection, PF value, loading voltage, safety grounding wire.

3. Laws and industry regulations: certifications requirements, environment requirements, EMC requirements.

Six points for checking the power supply quality:

1. Environment: power supply should have wide working temperature range, good humidity performance and high protection level and so on.

2. Input voltage: to make sure normal output, the power supply should have wide input voltage so that it can be used well in both high voltage condition and low voltage condition.

3. Power factor and conversion efficiency: the higher power factor the better for power supply because higher power factor is good for improve the utilization rate of power grid, so as the conversion efficiency does because it can improve the effective power utilization rate and reduce the subsequent cost.

4. Voltage stable accuracy: power supply should have good voltage characteristic to ensure no voltage fluctuation when it is under light load and heavy load conditions.

5. Material grade: select international real-name brand components can prolong the service life of the power supply.

6. Certification requirements: due to the third party supervision, the materials for certificated power are restricted by the certifications, it has more reliable quality.

Different led display installation Summary

Generally speaking, the led display installation structures can be divided into floor standing type, building face side wall mounting type and roof top fixing type, each type has different stress and strain characteristics.

By comparing the finite element analysis of three kinds of supporting structure system, HSTV gets the corresponding optimization scheme for each supporting structure: the cantilever mast for floor standing structure should use circular cross section; the wall mounting type structure should use composite truss; the roof top fixing type structure should use space truss design. By making optimal design against the key joints on the supporting structure and making shear key or cross-shaped stiffening rib construction measures to optimize the node stress state, it can improve the safety performance of the supporting structures.

Floor standing supporting structure:

Floor standing led displays are usually installed in city squares or important traffic cross roads, HSTV suggests to use space steel truss structure. The foundation structure is made of 2 pieces of space lattice columns which are composed by 4 pieces of steel columns, and upper part which is for installing display will use multilevel horizontal space truss structure, in this way the structure can meet both the requirements of structure stress and the requirements for maintenance space preset.

Wall mounted led display installation structure:

There are limited space for floor standing installed led displays in cities because of the dense constructions, in order to make full use of led display dynamic image ads display functions in city commercial areas, the led displays are usually mounted on the building face side.

According to the building face side condition and  convertible condition as well as the display installation height above ground, the led display installation structures are divided into wall mounted structure and roof installation structure.

Wall mounted installation structures usually adapt a steel structure fastening on the building face side and the led display is fixed on the structure, between the display back side and the building face side there is a maintenance space for the display.

Roof installation structure

Because the wall mounted led displays cover large area of the building face side, it can affect the indoor lighting, thus wall mounted led displays are usually used for shopping mall and other large commercial building. The moderate height office building and residential constructions will install the led display on roof.
