INDOOR LED SCREEN FOR MEETINGROOM
LED Display Screen is more and more popular,especially outdoor led display widely used for outdoor advertising with large led screen size, large size means high power consumption , a dozens of square meters led video wall usually reach tens of kilowatts, with numbers of led display screen increasing, energy issue is becoming more and more important for led display industry all over the world, So how to make a Lower Power Consumption Energy Saving LED Display becomes an important subject in LED display design.
A truly Energy-Efficient LED Screen, not just improvment of led screen hardware and led control software technology, but aslo the overall program on the results of led display screen innovation. For example, Outdoor P16mm 1R1G1B LED Display aim at reducing the cost of electric power, and the energy-saving efficiency reached more than 50%.
Energy Saving LED Display Features:
High Brighntess LED Low Voltage: Reliable LED Chips with Low Voltage but High Brightness to 7000-7500 Nits.
Low working Voltage: To reduce electromagnetic interference ;Adopt double circuit 2.8V & 3.8V for Modules and Control system. LINSN LED will bring you to learn more about the working principle of energy saving led screen.
ICN2049 is a Common Cathode Drive IC designed specifically for energy saving LED display, using 16 channels constant current output same as common IC: ICN2037. But it works at a lower and more stable voltage environment. Making the led screen to save energy effectively.
| Function Contrast | ||
| Item | Common IC: ICN2037 | Energy Saving IC: ICN2049 |
| Output current setting range | 3～45mA@VDD=5V 3～30mA@VDD=3.3V | 0.5～25mA×16@VDD=5V,VDS =0.3V 0.5～20mA×16@VDD=3.8V,VDS =0.3V 0.5～15mA×16@VDD=2.8V,VDS =0.45V |
| Current accuracy | Between channel :< ±3.0% Between ICs :< ± 2.5% | Between channel :< ±2.0% Between ICs :< ± 2.0% |
| Working Voltage | VDD=3.3～5V | VDD=2.6～5V |
>>.From this sheet, the voltage(U) of ICN2049 is lower than ICN2037. Consider both of them are constant current driver, so the current(I) is constant.
>>.At the same time, according to the data, the output current of ICN2049 is also smaller than normal IC.
>>.P=U*I, when both U & I decrease, it means that the power consumption has been greatly improved.
Above all, you will find that these design changes are mainly to reduce voltage and current, so as to achieve energy saving, lower consumption, lower temperature effect.
