2024-07-05
Overview of LED application fields
The LED market covers a variety of applications, including LED displays, traffic lights, automotive lights, LCD backlights, mobile phone keyboards, digital camera flashes, decorative lighting, street lights, and general lighting.
In the medium to long term, a new factor driving the growth of the LED industry will be the general lighting market.
In view of the global trend of reducing carbon emissions, the demand for LEDs in the general lighting field will be very strong. LEDs have low power consumption and are environmentally friendly, reducing the pressure on the lighting industry to save energy and reduce emissions.
The application of LED light source in urban landscape lighting
What urban landscape lighting pursues is not brightness, but artistic and creative design. LED products should be able to find its place of use.
LEDs with small luminous angles have strong directionality and can be used for local accent lighting. Adding scattering agents to packaging materials can achieve a 175-degree luminous angle, which is suitable for lighting in a wide range. The problem is that the current construction units in urban nightscape lighting are too pursuing high-end lighting. Brightness makes it difficult to provide designers with a large enough range of choices.
Currently, the main LED light sources commonly used in urban nightscape lighting projects include:
1. Linear luminous lamps
LED linear luminous lamps (tubes, strips, curtain wall lights, etc.): The contour lighting effect produced can replace traditional Neon Lights, magnesium-neon luminous tubes, and colored fluorescent lamps.
LED linear light-emitting lamps have been widely used in the outline lighting of urban buildings and the railing lighting of bridges due to their good weather resistance, extremely low light attenuation during their lifetime, changeable colors, and flowing lighting effects.
Taking the outline light of a building as an example, it uses the principle of combining the three primary colors of red, green and blue LED light sources and can be changed in different modes under the control of a microprocessor, such as water ripple continuous color change, timed color change, gradient, Transients, etc., create various effects of high-rise buildings at night.
2. Decorative lawn lights, landscape lights, bulbs, etc.
In urban streets or green spaces, the luminous parts are designed into various structures such as rings and strips to partially illuminate the lawn; at the same time, they become decorative elements in the daytime environment.
In actual projects, it is often used in conjunction with gas discharge light sources as decorative lighting. LED light sources of various shapes and functions, such as lawn lights, landscape lights, and bulbs, can be combined into colorful light phantoms.
This "multi-color, multi-bright spot, multi-pattern" change reflects the characteristics of LED light sources.
3. Underwater lights
LED underwater lights are placed underwater for lighting of water bodies, and the protection level should reach IP68. Rated working voltage DC12V.
The low-voltage operating characteristics of LEDs make them safer than any previous lamps. The advantages of long life also make maintenance more convenient, and the lighting effects produced are richer than commonly used PAR lamps and gas discharge lamps.
4. Ground lighting: underground lights, luminous floor tiles, stone lamps, etc.
Floor lamps can be miniaturized by using LED light sources. It can be used as ambient lighting on the one hand and as luminous decorative lighting or guiding functional lighting on the other hand.
Depending on the specific floor paving structure, the light outlet area of the lamp can be large or small. Embedded stone lamps and floor tile lamps are trimmed to match the stone pavement, achieving a harmonious and unified effect of environment and light source.
5. LED lamps that use solar cells as energy
The low power consumption of LED makes it possible to use solar cells as energy. The extremely low operating voltage eliminates the need for DC-AC conversion circuits required for traditional light sources, greatly improving energy utilization, expanding the application range of lamps, and saving energy. , conducive to environmental protection.
2. Application of LED dynamic luminous characters in high-rise buildings
Due to the energy-saving characteristics of LED, LED has entered urban lighting projects. Many iconic landscapes, lighting projects, and lighting night scenes have begun to use LED, a colorful and energy-saving new solid light source.
Traditional urban lighting consumes a lot of power. It usually uses passive lighting of buildings, which consumes a lot of power. If LED active lighting is used for lighting, the power consumption is only 1/20 of that of passive lighting.
LED light source dynamic luminous characters are installed on the top or wall of the building in the form of text or logo. LED is used as the light source, high-brightness LED chips are selected, and the control system is used to dynamically video control the text or logo. The unique design makes the traditional Outdoor advertising has new possibilities.
The richness of its colors greatly exceeds the limitations of traditional neon lights. Coupled with the relatively power-saving characteristics and the long life of LEDs, it greatly reduces maintenance costs.
In the future outdoor advertising sign market, LED technology will complement neon lights. LED light sources will play an increasingly important role in outdoor advertising lighting with their significant advantages such as energy saving and long life.
The three-dimensional luminous characters with built-in LED light source have excellent visual appeal, soft colors and rich dynamic effects. At the same time, LEDs operate at low voltage, are safe and reliable, and have incomparable advantages over other light sources such as neon lights in terms of service life and maintenance costs.
Compared with neon lights, LED light source dynamic luminous characters are not composed of light tubes with a strip structure, but are composed of LED light lattice that are independently controlled, so the changes are extremely rich. It is different from the passive light-emitting of light boxes, street signs and magnetic flaps, but adopts single-point active light-emitting, so the display effect is more uniform.
Using advanced communication control technology, the LED light source dynamic luminous character system is all controlled by semiconductor circuits, so there is no possibility of mechanical failure like a magnetic flap. At the same time, the control voltage is between 5 and 12 volts, which is quite safe to use.
Due to the shortcomings of high power consumption, high failure rate and low luminous conversion rate, the current neon signs are no longer acceptable to the majority of customers. LED light source dynamic luminous characters have the characteristics of high luminous brightness, dazzling and changeable display effects, long life and very energy saving, and will be recognized by users in this field.
Simply put, LED light source dynamic luminous characters have the following advantages:
1. High brightness. The brightness of the product exceeds all other current lighting equipment.
2. Windproof, waterproof and dustproof. It can operate around the clock and is not affected by harsh weather conditions.
3. Strong visual impact. Rich colors, fonts, patterns, and animations can be created at will.
4. Replace traditional neon lights and other indoor and outdoor signs and lighting systems in a flexible and changeable way.
5. Energy saving and low operating cost. The power consumption of the product is small, only one-tenth of traditional neon lights.
6. Advertising is effective.
The combination of dynamic and static display methods, rich and changeable display content, low operating costs, high-security design and long service life can greatly improve the return on investment of advertising investors.
This allows advertisers and advertisers to use limited funds to perform unlimited and exciting advertising content, thereby maximizing the advantages of outdoor advertising media and truly achieving a win-win situation for advertising investors and advertising users.
3. Application of Led Lighting in outdoor new media
First, there are two polarizing trends in outdoor new media. One is the popularization trend, and the other is the super-segmentation trend.
Since the emergence of Focus, everyone has completely accepted the concept of segmentation, sometimes even to the point of overflowing. Today's outdoor new media is mainly channel media, mainly derived from the audience's contact points.
Every touchpoint may generate new media. It should be said that excessive segmentation has caused disgust among the audience.
In the past two or three years, there may be a major reshuffle in this industry, and many segmentation trends have reached a certain end.
In addition, there is the trend of popularization, especially in relatively closed public environments. The trend of popularization will be more obvious in the past few years.
In the past two or three years, the large-scale production of segmented new media may lead to relatively large integration. When things go to extremes, there may be a process of integration with each other.
Second, from a subjective point of view, in the next 10 years, in big cities, traditional outdoor media may gradually be replaced by new forms such as outdoor video and outdoor LED.
As we all know, audiences spend more and more time outdoors. Traditional outdoor media is more about the concept of points. In fact, the coverage and audience stay time are relatively small.
At the same time, new technologies in the field of outdoor media are relatively active and developing rapidly, which will further stimulate the growth and maturity of new media.
The growth of outdoor advertising mainly comes from outdoor video and outdoor LED. Mobile TV on public transportation increased by more than 200% in 2007 compared with 2006, and the growth rate of outdoor LED was also astonishing, reaching 148%.
Third, the judgment of new media may be quite different from that of traditional media. Traditional media relies more on the influence of content to achieve rise or continued success.
There are four factors that affect the continued success of outdoor new media, namely channel resources, technology, capital and brand.
