In today's wave of digitalisation and informationisation, LED display like a bright star lights up the city streets and alleys, indoor and outdoor places of all kinds, from the giant advertising screen in the busy business district to the high-definition display panels in the conference room, the breadth and depth of its application continues to expand.LCF editorial will analyse the power of the LED display in this article - a key indicator of energy consumption, heat dissipation, operating costs and stability. -This is about energy consumption, heat dissipation, operating costs and stability of the key indicators.

The basic unit determines the power ‘foundation’.

LED display consists of countless LED lamp beads, lamp beads is the power composition of the basic ‘bricks and mortar’. Common small power LED lamp beads rated power of about 0.06-0.1 watts, mostly used for indoor fine display scenes, such as small conference rooms, home smart device display, etc., they are arranged in a dense matrix, relying on the number of cumulative brightness, the overall power consumption is relatively mild; medium power lamp beads (0.2-0.5 watts) is a common indoor large screen and some outdoor small size screen ‘favourite Medium power lamp beads (0.2-0.5 watt) are the ‘favourite’ of indoor general-purpose large screen and some outdoor small-sized screen, and frequently appear in the field of shopping malls' guide screen and community announcement screen, balancing the brightness demand and energy cost; high-power lamp beads (1 watt and above) are like “bright giants”, and are the trustable choice for outdoor large-scale advertisement and stadium's main screen, with a strong output of a single lamp to support the eye-catching visual effect at a long distance. The number of lamp beads can be used less but bring high power sum, a standard outdoor P10 full-colour screen (about 10,000 lamp beads per square metre), if 1 watt lamp beads, only lamp beads power consumption of about 10 kilowatts per square metre, not counting the additional energy consumption of the drive circuit and so on.

Pixel pitch leads to power ‘variables’

Pixel pitch, i.e. the centre distance between adjacent LED beads, is a subtle factor that affects power. Outdoor display, for example, P5 (5 mm pitch), P8, P10 specifications are common, the smaller the pitch, the number of lamp beads per unit area soared, the power with the ‘boat rises’.P3 small pitch LED screen for high-end outdoor advertising space, more than 270,000 lamps per square metre beads (assuming 0.2 watt lamps beads), lamps beads power of nearly 55 kilowatts / square metre, although high energy consumption, but the power of the LED lamp beads. Square metres, although high energy consumption but in exchange for high-definition fine picture quality, sharp text edges, image details appear; On the contrary, P16 large screen, sparse lamp bead layout, power in the same brightness requirements can be reduced by several times, the picture is slightly ‘granularity’ but to meet the long-distance, large-size display, such as high-speed roadside giant publicity screen, passing cars fast, large spacing does not damage the Visual communication, but also fits the energy-saving needs.

Display colour and brightness ‘rewrite’ power curve

Colour and brightness is the LED display ‘eye-catching’ magic weapon, but also the power ‘regulating valve’. Full-colour screen need red, green, blue light beads, different colours have different luminous efficiency, light blue often than red energy consumption is about 20% -30%, full-load display of complex and gorgeous picture, power is higher than solid colour, static picture. Brightness adjustment is more like ‘power magic’, manual or automatic photocontrol light, daytime glare screen ‘full power’, adjust the current to let the lamp beads full light, power to peak; dusk, night drop brightness, power proportionally reduced, intelligent street light pole incidental LED information screen attached to the intelligent street light pole is an example, according to the ambient light flexible power, in order to ensure that the information can be read at the same time energy saving of more than 50%, to extend the life of the equipment, reduce operation and maintenance costs.

Additional circuits and usage scenarios ‘superimpose’ power levels

Additional systems such as drive circuits and power supplies quietly add to the power bill. High-quality high-efficiency driver chip, low-loss power conversion, accurate delivery of lamp beads, low-quality heat, power waste, so that the entire power extra 5-10%; cooling fan, air conditioning and other temperature control equipment for high-power screen ‘escort’, their own power consumption should not be underestimated, large outdoor screen temperature control power consumption accounted for 10% -15% of the total power. 15 per cent. The use of the scene is ‘fixed’ power mode, shopping malls indoor screen often constant temperature, low-brightness operation, power stability; traffic hubs outdoor screen all-weather, high-brightness duty, rain or shine under the power continues to be high, special scenarios, such as the emergency command vehicle vehicle-mounted LED screen, taking into account the capacity of the vehicle's power supply, the design of low-power, high-efficiency mode, to protect the key information Display at the same time does not ‘drag’ vehicle range and power safety.

LED display power is not a single fixed value, is the lamp beads, spacing, colour brightness, circuitry and scene of multiple elements ‘ensemble’ results. Understand this complex mechanism, help users in the purchase, installation, operation and maintenance of all phases of reasonable control of energy consumption, in the brilliant visual presentation and green operation to find a ‘golden balance’, so that the LED display screen shine and ‘light’ in the era of the stage.

The above is the LCF editorial to put together the LED display power of the relevant knowledge, I hope to help you, and welcome you to add or correct.LCF is a collection of research and development, intellectual property, sales, operation, service in one of the national speciality and speciality of the small giant enterprises, national high-tech enterprises.
