Energy and Money Saving! Talking about common shade LED technology
Conventional common sun LED display after years of development, has formed a stable industrial chain, led to the popularization of LED display, however, also has the shortcomings of the screen body temperature is too high and power consumption is too large. After the emergence of common shade led display power supply technology, caused the market a high degree of concern. The power supply method can realize the highest energy saving 75% of the excellent said to attract the attention of the market, common shade led display power supply technology is what? Why is it so good? Below to take you to find out!
First, what is a common shade LED display? Common Negative” refers to the common negative power supply, common negative LED display will RGB separate power supply, accurate distribution of voltage and current to the red, green and blue lamp beads, the current through the lamp beads and then to the negative pole of the IC, the positive pressure is reduced, the conduction internal resistance is small.
Second, what is the difference between common negative / common positive LED display?
1 power supply direction is not the same: common positive LED display current flow from the PCB board to the lamp beads, RGB lamp beads unified power supply, increased circuit forward voltage drop; common negative LED display current through the lamp beads and then to the IC negative, positive pressure reduction, on-resistance is small.
2 power supply voltage is not the same: common sun LED display usually give red, green, blue lamp beads a higher than 3.8V voltage (cf 5V unified power supply, power loss; common shade LED display according to the red, green, blue three chips actually need the voltage (red lamp beads voltage requirements of 2.5V or so, blue, green lamp beads voltage requirements of 3.8V or so) separate and accurate power supply, power loss is less, LED display The heat generated in the work is also much lower.
Third, the common cathode LED display why heat is lower: through the above common cathode and common sun power supply mode of comparison, know the common cathode LED display than the common sun LED display power consumption is much lower, however, the common cathode LED display than the conventional common sun LED display heat is much lower.
LED module local will use aluminum chassis design, PCB board heat directly through the aluminum heat transfer, the light-emitting chips and driver IC heat generated through the aluminum chassis directly to the outside heat dissipation, thermal resistance is small, heat transfer area is large, the entire aluminum chassis is the LED chip heat sink, the chassis is made of die-cast aluminum alloy, the flatness and consistency of the LED display is also greatly improved, and to ensure that the hardness and strength of the product under the premise of reducing the weight of the product, saving energy. Under the premise of ensuring the hardness and strength of the product to reduce the weight of the product, saving information.
Fourth, the common yin LED display save money save where?
1, save electricity, save operating costs: accurate power supply to reduce the LED display power loss, reduce operating costs.
2, save device input cost: low heat temperature rise can also save air conditioning, fans and other cooling equipment.
3, save maintenance and repair costs: the follow-up of the fully enclosed die-cast aluminum chassis, the components one by one to maintain up, so that the LED display life is about 2 times the ordinary screen.
Fifth, the advantages of common shade LED display?
1, super heat dissipation, small power loss, low heat, low temperature rise of the screen body, long life, good display effect.
2, super waterproof, dustproof, anti-corrosion, anti-ultraviolet, V0 fire norms, protection level IP68 can be directly placed in boiling water inside the boil, can withstand 130 degrees high temperature test, can be placed in a 3-meter pool under the immersion and normal work; extreme cold, heat, high ultraviolet and other harsh environments, adhere to the non-deformation, no aging, no water leakage, no fire.
3, galvanized locking design, easy maintenance before and after the box body is thin, the thickness of the whole screen is small, can be free of channel free air-conditioning installation.
4,Cold light source
High brightness, ultra-high refresh, elimination of ghosting without trailing, the picture is more fresh and delicate, high fidelity.
5, energy efficient and more environmentally friendly, can achieve energy saving of 75%.
Has been the key factor affecting the service life of LED display products, and “common shade LED display” can precisely solve these two problems. The actual measured data show that: the same specifications of products, the same brightness, common shade LED display screen temperature than the conventional co-positive LED display products, the screen temperature is more than 20 degrees lower than the conventional co-positive LED display products, power consumption than the conventional co-positive LED display products more than 50% lower. According to statistics, the global annual production of LED display more than 3.5 million square meters, according to 300 watts of power consumption per square, 1.75 billion kWh of power consumption per year. This is not counting the power consumption in the production process. If all the use of common shade LED display, will save at least 725 million kWh of electricity for the society every year. I hope that the future of common shade LED display can become a competent competitor in today's LED display market that can really bring great economic benefits and value to customers!
