LED modules
LED modules (otherwise - clusters), faced primarily by those who have their own business and faced with the selection of backlighting for the banner. The fact that it is outdoor advertising - the main area where LED-modules are used. Modern LED technology can make the signage expressive and bright. To be a success for the institution began to enjoy, it must be remembered and want to visit. LED clusters do an excellent job with this task. It should be noted, today LED modules have even left far behind their competitors, not only light bulb Illich, but also halogen with fluorescent lamps.
Externally, the module looks like a small board with a few LEDs placed, but the device is functionally designed to control light designs. These products on the market represented myriad, so if necessary to choose from what is needed. LED-modules are sold with different enclosures, LEDs in them occur in varying quantities, and varying degrees of light, and color schemes: there is a monochrome clusters, a color combination. That is. planning in his head all sorts of options, imagination and creativity can not be limited - thanks to a variety of LED modules, all ideas embodied.
Varying on top of everything else and the size of LED clusters. So, for the same number of crystals corresponding to two or three types of size. For example, clusters with identical characteristics, which have three crystals, can go with a short body, with an elongated and with a square. In the first case, the crystals will be set often, in the second case - rarely, in the third one their arrangement will take the form of a triangle. The choice of outlines depends on what your goal is. If you need a modest sign, the light box which is shallow, up to 10 centimeters, you need a short body, because there clusters are packed tightly, if the letters on the sign should be large, from half a meter, you must take an elongated case. The smallest two-chip modules fit perfectly into complex configurations with multiple angles. Large boxes with a depth of more than ten centimeters and letters on wide legs require a square four-chip clusters.
The advantages of LED emitters, compared to other technologies used in advertising illumination, are obvious: due to their compact size they can be hidden anywhere. Thanks to the lightness, maximally simplified mounting work, you need only choose what to take - glue, double-sided adhesive tape, or hardware.
At the same time, deciding to buy LED modules, you can decorate anything with backlighting - and public buildings, and landscape gardening, and even interior details. If we talk about how much or little consumes such a module of electricity, it is worth noting that one-watt cluster takes as much electricity as a regular 10-watt incandescent bulb or 13-watt halogen.
More LED clusters are distinguished sverhdolgoy operational warranty. Thus, the factory rules prescribe all 50 thousand hours of continuous operation. Given this fact, the price for them seems ridiculous. Listing the advantages of LED modules, it is impossible not to mention their safety. This is explained by the ultra-low supply voltage (up to thirty volts).
How to choose LED-modules for signage
During the selection of modules for signs should take into account how bright it should be. For example, the standard banners that we meet on the street, go with numbers from 1200 to 1800 Lux and crystals 3528. Suppose our sign is 13 centimeters deep, the most typical would be to choose a three-crystal module. If the density of clusters will be 96 pieces in a square meter, you get a brightness of 1350 Lux, if the density is increased by about half, the figure will be somewhere around 1850 Lux. If you increase the brightness of the sign by adding a fourth LED 3528, you can achieve a brightness of 1550 lux, with a density of 80 pieces per square meter.
If you want the light box to shine even brighter, take crystals 5050. So, if the cluster will be the same three LEDs at a density of 80 pieces per square meter, we get the brightness at 3700 Lux, if four and a density of 72 pieces per square meter - then at all 4400 Lux.
Do not be afraid to overpay! Cheapness - it is poor quality clusters, it is possible breakages, the cost of repair work. You can not buy good LED modules for pennies. The price difference is, above all:
- The quality of the assembly, which is the key to tightness and even placement of modules on the wire, which is very important during precipitation;
- reliability of fasteners, which affects the speed of installation work;
- And the quality of LED crystals, which prevents premature failure and helps to withstand temperature spikes.
However, it is also worth realizing that regardless of cost and operating conditions, after 2-3 years of continuous operation, all LED signs are slightly dim. However, the loss of brightness is not very significant - no more than 25%.
