Chau Ming technology new energy LED display

In April 19th, just approved in the GEM Listing Shenzhen unilumin Polytron Technologies Inc launched a new energy-saving LED screen, the display has taken a number of measures, the LED display is a new generation of more environmental protection and energy-saving.

It is understood that the domestic and foreign counterparts is widely used red green blue tube unified 5V power supply, in the display of energy-saving technology is mainly driven by constant current IC increase LED light duty ratio method to achieve the same brightness maximum reduce the peak current of LED through the use of built-in PWM, and luminescence properties of LED is luminous efficiency the efficiency of small current is larger than the current, in order to achieve energy saving, or choose the control system to support built in PWM constant current driver to improve the utilization rate of the LED, or the PFC switch power supply with power factor correction, improve the power factor and the conversion efficiency of display. These methods are based on improved energy saving measures such as the basis of upstream technology improvement and development of chip, power supply, control system on the screen, as manufacturers have little power to pay attention to the related electronic circuits, such as blue and green for the same driving voltage and the circuit must have unnecessary power consumption etc.. Low dropout driver chip with improved power supply system, to reduce the unnecessary power consumption on the module in the industry with a certain degree of advanced.

According to reports, with 200 square meters of outdoor LED screen as an example, under the same brightness screen average power consumption is 588W/ square meters, daily consumption (12hours) for 200X588X12=1411KW, the monthly electricity consumption (30 days) 1411X30=42330KW, the annual electricity consumption (12 months) 42330X12=507960KW; and such screen power consumption is 285W/ square meters, which is calculated the annual electricity consumption of 246240KW, can save more than half of electricity and electricity.

Shenzhen unilumin Polytron Technologies Inc, is a national high-tech enterprise, "11th Five-Year" national "863 Plan" project unit, China quality products of green lighting manufacturing enterprises, R & D and Industry Alliance national semiconductor lighting project director unit, detection Easy Access enterprises, LED road lighting, LED display, commercial lighting, lighting Home Furnishing other products and solutions provider.
