Mobile RGBY traffic LED energy-saving module

Technical field

This innovation is an upgrade of the electronic technology. To be more specific, it is an integration of the full-color LED display and the single color yellow LED display.

Background research

With the development in the LED display industry, the production and innovation of LED display screens are constantly changing to meet varieties needs from different industries and energy-saving requirements. For example, the traffic signs can only use the color yellow and the power consumption of solar LED display must be low. However, the power consumption of LED display screens is quite high at the moment, and the screens for transportation departments can only use the color yellow. Therefore, the concept of a new type of energy-saving LED display that can be applied to more applications has been proposed. In terms of energy saving, existing manufacturers have adopted the method of reducing voltage supply to save energy. However, due to the low voltage and power loss in transmission cable, only a small amount of the power is saved while the brightness of the display is greatly affected at the meantime ended up failing to meet the user's requirements, which is not a fundamental breakthrough at all. Moreover, the existing LED (RGB) full-color display isn’t qualified for the traffic signs as the wavelength of the yellow color doesn’t match the requested wavelength, which means the current traffic signs are qualified but can only be used for traffic, which resulting in a waste of resources.

My Innovation

Mobile RGBY traffic LED energy-saving module is the solution to the above issue that achieves the purpose of energy saving and multi-purpose through a new method and structure leading the innovation of LED display screens industry to save electricity, reduce air pollution, protect the environment, and cut costs.

This innovation discloses a scheme of an energy-saving module of a Mobile RGBY traffic LED energy-saving display. The scheme is composed of LED lights (RGBY) which are consist of a 4-light group of red (R), green(G), blue (B) and yellow (Y), DC synchronous rectification dual output buck component, 1C drivers, and frames. Key specifications include:

• Partitioned voltage has been directly input to the LED light groups through DC synchronous rectification dual output buck components, and the DC synchronous rectification dual output buck components and LED modules have been combined

• or separate DC synchronous rectification dual output buck components to be connected within 0- 10 cm to reduce the power loss in cable transmission; input voltage 8-36V has been converted into 2.3-2.5V and 3.3-3.5V through DC synchronous rectification dual output buck components, powering the LED lights group and IC drivers directly to reduce the power loss in wire transmission.

This innovation overturned traditional methods of reducing the power supply voltage but adopt the most efficient power supply voltage. Full-color image or the yellow image can be used separately or on a partition basis according to users’ needs. To sum up, energy saving and cost reduction purposes are achieved in this innovation. In addition, two LED display modules are combined into one LED display module, which can be used wisely under different circumstances. The solar panel: LED display is 1:1 (1 square meter display with 1 square meter solar panel)

Finally, the RGBY (red, green, blue, yellow light) is illuminated by the driver IC (4).

Conclusion

In conclusion, energy can be saved by replacing the 5V single-channel powersupply input module by dual-channel power supply 2.3-2.5V and 3.3-3.5V input modules, and partition powersupply according to the VF value of red, green, blue and yellow lights (RGBY).

Description

The method of 5V power supply for LED display is dominating the market at the moment, in which resistors are needed to depressurize to the proper voltage for the VF value of the lights requested, and lengths of connecting wires between the power supply and modules lead to resistance and power loss of circuits.

In this proposal, the DC synchronous rectification dual output buck component is added and the resistance is removed, and the power is directly supplied according to the VF value of the light, thereby saving the loss of the resistor. This scheme must combine the DC synchronous rectification dual output buck component with the module panel, or to combine with separate DC components within 0-10 cm pitch to avoid the losses of the voltage and current. Base on the principle of high voltage, low current, and less power loss in transmission. Brightness issue has been resolved because of the 8-36v wide voltage power supply, voltage fluctuation does not affect the stability of the DC buck component, and to ensure the consistency of the LED display brightness.

RGBY (red, green, blue and yellow lights) is controlled by the software. Full-color image mode or the yellow image mode can be selected or on a partition basis according to users’ needs to satisfied traffic management needs and commercial needs at the same time.

Example: The power consumption of an ordinary outdoor P10 module is about 700W per square meter when the power supply is not partitioned, however, it is decreased to 424W per square meter when using the partitioned power supply. With this innovation, the outdoor bright P10 module has a maximum power of 60 watts measured in one square meter and 15 watts in normal use that is less than the power consumption of a notebook.
