Before, the customer used low voltage LED strip surrounding door-header with total length 70 m (the length of each shop may be different).
The problems of Customer: The low voltage light source needs to connect several main cables for which the longer main cables will cause voltage drop. In order to solve the problem of voltage drop, it requires to place several power source switches to connect the main cables for supply of electricity, hence it results difficulties in arrangement of power sources which is unable to hide. It influences its entire effect and appearance.

| In the early stage contacting, for customer samples, it adopted the solution of RS and LJ high voltage LED strip. Due to the length of high voltage hard LED strip cannot be cut randomly, its four corners cannot install light resources modularized. Hence, the customer abandoned using this type of products; | The long cascade connection of high voltage soft strip does not require power source. Normally, this could be suitable for the project, but the actually situation is that the outdoor use waterproofness of high voltage LED strip cannot be ensured. Also, it requires to install the light source at site, however if taking place modularized installation at the factory, it again encounters the problems of random cutting. | Single unit cuttable, no need of power source, outdoor IP67, easy for modularized assemble, etc. which attracts customer, it solves several problems and finally the customer chose this solution. |
2400mm x 450mm x 12mm, each module uses 24PCS high voltage module, it divides in two roads, between different modules, it uses the triplet fast cable connecter for link conduction which was developed and produced by our self; The factory finishes production the modules and at the site it only requires a screw driver to install the connecting circuit parts which makes easy, quick and safe.
The building is not very tall and its channeled characters are 4 meters high in size which count totally 11 of them.

| On the reason of the owner, this project was done 2 times already and this is the third time. For the two times done before, it was adopted low voltage light source which consumed 20000PCS modules and 10 working hours for light source installation each time (each working hour means 10 workers working one day), and it was winter day that makes a slow working efficiency. | After using high voltage 2.5W modules, the actual number used was 3150PCS and it just consumed 2 working hours to finish. |
| Site installation: it requires 45 pieces of power supplies at 400W, cabling + switchgears, material cost + installation time, it demands a high cost. | Site installation: Fixing the channel letters at site, electricity connecting work done by electricians, just 1 hour to be done, and in comparison, of low voltage light source, this saves several times of working hours. |
4000mm x 4000mm x 120mm, bold, 11 characters, 176 m2 area, effective area is around 105 m2 , 3150pcs used and 30pcs/ m2.
There are three 80%s: The module of MFW8A3D/2.5W/AC 220V reaches light effect 90LM/W, high brightness, uniform light, suitable for channel letters thickness at 12 – 20cm. The light numbers required are 80% less than normal demand of low voltage modules; The installation woker working hours 80% reduced, and the time of site electricity connection 80% less as well.

The problems of Customer: It was difficult to arrange the power supplies at the site both indoor and outdoor.
High voltage 1.6W and 2.5W, the high voltage 220V can easily solve the requirements of different sized lights interrior and exterrior, easy site installation, less numbers of LED, and uniform light.
LOGO Size: 1500mm x 1500mm x 150mm, surface based with 3M lightbox canvas, laminated with 3M film, 40PCS used and 18PCS/m2.

The problems of Customer: Before, it adopted low voltage modules and advanced power supplies from famous suppliers. In later use, due to too much interior connections, the protection insulations aged after long time, and finally got short circuit. As there was no high accuracy of protection function for power short circuit, it resulted fire on the signage for which there were burning parts dropped off and burned a car. It made a very bad influence. Before customers got to know the high voltage modules, they would add a protector in circuit to prevent short circuit hence to avoid such fires to happen.
There is a good design in the high voltage modules of our factory that reasonably fits customer demand for which there is a fuse circuit in each module. When the current exceeds the range allowed, the fuse wire will cut off automatically hence protect the safety of entire circuit； The product advantages of high brightness, large angle and less numbers used on single unit area plays information roles when the customers installed and it saves a lot of working time for customers.

This project is to improve the existing light source inside light boxes, upgrading, the left one is original brightness effect and the right is the brightness effect after improvement.
The problems of Customer: he original light solution used low voltage LED strip which, after being used in 2 years, gradually appeared flash and partial failure of illumination. As the importance of rail station, it is, the maintenance has to be done after 11:30pm once the operation service stopped, and leave only after 5:30am, it is very inconvenient and requires permission in advance. The workers at the site reported that it needed to change power supplies and each time it took 1-hour time, but they had to stay inside the train station until morning of next day, the cost of time and workers is very high.
The Advantages of High Voltage LED Modules No need installation of power source, 5-year guarantee, free of maintenance in 5 years that makes once installed five years free.
The light box size 4920mm x 2200mm x 90mm, very thin, work very high above ground, less working efficiency, the later improvement solution is to put the modules inside the aluminum structure and its sizes according to lightbox size that saves installation time at site.
