Tip 1: Applying LED bulbs
Not so long ago appeared on the market LEDlamps gradually "master" all new fields of application. High performance characteristics led to the use of LED lamps in everyday life, industry and even plant growing. Today, the production of these devices is improving, which leads to cheaper products and even wider distribution.
Most of all LED lightsare in demand wherever much light is needed. Their use is due primarily to high profitability. Even taking into account the considerable cost of the device itself, payback with intensive use occurs quite quickly; while the durability of the LED lamps should be taken into account. And on this indicator for today they do not have worthy competitors.
Street lighting and public utilities
According to experts, the use of LEDlighting in the housing sector can bring savings of up to 200 million rubles. in a year. And these figures apply only to objects where color quality is not required. In particular, it can be lighting in the elevator, highlighting house numbers, staircases. A distinctive feature of LED lamps is their anti-vandal essence; in products there is no glass, and it is not so simple to destroy monolithic polycarbonate. The main zone of use of described fixtures on the street is highways, highways and footpaths. LED lights have a high quality of color rendering, which facilitates the perception of information by the driver and leads to a reduction in the number of accidents. The use of lamps in park areas contributes to the safety of citizens. According to the norms, the illumination of smooth tracks should be at least 1 lux, and the unevenness should be 5 lux. LED lamps fully meet these requirements. Also in the park areas, lamps can play the role of landscape lighting.Advertising and architecture
One of the factors that led to the use ofLEDs in advertising and architecture - "natural" protection of lamps from atmospheric and mechanical effects. In the advertising business, building lighting, LEDs "go in great demand" due to the possibility of using almost everything visible in the human eye range. Various combinations of blue, red, green colors give originality, attractiveness to any advertisement. Architectural lighting is not just a banal lighting of a building at night. This is part of the overall design solution that gives the building an extraordinary look, emphasizing its uniqueness.Greenhouses
In modern crop plantstoday the most common are sodium lamps. However, in them only 1/3 of the radiation "goes into business" (securing photosynthesis). The rest of the energy goes into heat. For example, an economy of only 5 hectares using sodium lamps consumes as much energy as all the lamps of the Moscow Ring Road! LEDs, in addition to saving energy, provide a spectrum of illumination, the most favorable for the flow of photosynthesis. In the western countries (England, Holland, Austria, etc.), LEDs have long superseded sodium lamps.Tip 2: Is the diode lamp the future of lighting?
Widespread use of diode light sourcesmakes us wonder: will this technology provide effective energy saving in the future or high cost of products will not allow them to be used massively?
LED lamps made a breakthrough in the spherelighting technology, providing consumers with universal light sources that have low energy consumption and virtually unlimited lifespan. The principle of the action of light-emitting diodes is based on the ability of certain types of complex semiconductors to emit photons as the electric current passes through the region of the p-n junction. This radically distinguishes the LED from the filament that emits light only at high temperatures and has a limited life. The question concerning the massive use of LEDs for partial resolution of the energy crisis can not be answered unequivocally. On the one hand, almost half of the electricity in the household and administrative spheres of consumption is spent on lighting, so reducing this amount by a factor of ten can seriously ease the work on energy saving measures. On the other hand, the production of LEDs is an extremely complex and resource-intensive technological process.
Advantages of LEDs over conventional lamps
The design of light-emitting diodes assumes high termservice of light sources. The absence of an element that heats up to the radiation threshold in the visible spectrum excludes energy losses for the formation of heat. Also, the LEDs are very compact, which allows you to place several hundred radiators on a single panel, thus providing a high light output. LEDs can work in any climatic conditions, which can not be said about incandescent lamps and fluorescent light sources. In matters of decorative lighting, LEDs also have a noticeable advantage: by changing the amount of applied voltage and current, you can adjust the power and color of the radiation, which is indispensable for light advertising.Disadvantages of LED light sources
In addition to the main shortcoming,high cost of LED lamps, they are inferior to traditional light sources by some parameters. For example, the emission spectrum of LEDs is rather narrow. Light is generated with a high amplitude of oscillations, so the light source itself is visible from a great distance, but only illuminates a limited area. Also for LED lamps, the effective removal of heat is critical, since the conductor under the high temperature slowly decays and loses its qualities.The issue of large-scale use
LEDs, in principle, can replacetraditional light sources, providing significant savings in electricity consumption. Their high cost is not a significant counterargument. The multiply superior working resource makes the cost of such lamps equivalent to a common light source. The only obstacle is the lack of mass production and low popularity among the population, but these problems are resolved over time.Tip 3: What are the advantages of the LED strip
LED light sources produce not onlyin the form of lamps, but also in the version of a flexible printed circuit board covered with a layer of silicone. Such tapes are widely used in the field of light advertising and decoration because of their durability and versatility.
Structurally LED strip representsa printed circuit board, the components of which are printed on a flexible base. The board includes LED crystals coated with a phosphor of different shades, current-limiting resistors and conductive paths. These elements are hidden in the thickness of the silicone, which ensures their complete protection from the effects of the external environment. LED strip appeared after the lamps of the same type and immediately became widely used. Their popularity is due not only to the high performance characteristics of light-emitting conductors, but also to the original form. Due to their compactness and low power consumption, they are indispensable when creating lighting sets and outdoor advertising, and the presence of an adhesive layer on the back side allows them to be mounted on most types of surfaces. There are several types of LED ribbons, each of which has its own positive features.
