Led can save a lot of power to the country and users, saving a lot of man-hours for the contractor. The development of LED application technology has added new vitality to the highly competitive advertising industry. Its unique and different lighting situation is widely used in the production of advertising products. Different specifications of LEDs have different illumination angles and different brightness. So, how to choose the right LED for different products, so that it can maximize the efficiency and minimize the cost? The application and use of LED in luminous characters The three-dimensional luminous characters have the following requirements for the light source:
1. The complexity of the glyphs and the different specifications of different projects require that the light source be versatile without the glyph limitation;
Second, because the installation of the completed luminous word maintenance is extremely inconvenient, in order to reduce the maintenance cost, the light source is required to have a longer life;
Third, to have sufficient brightness, the LED lighting module made for the above requirements has the above functions.
There are two types of LED light sources for three-dimensional luminous characters: piranhas and straw hats. The piranha light module is suitable for luminous characters with a word wall height of 8-10 cm. In general, the piranhas at the heads of ¢3 and ¢5 emit light at angles of 90 degrees and 120 degrees. At this distance, the piranha light module is applied to the blister word, and the light can be completely radiated. Not only saves the number of modules, but also the utilization of light intensity is just right through the screen brightness meter test. For the short, word-shaped blister letters and engraved letters, the flat piranha module and the straw hat lighting module with a luminous angle of about 160 degrees are used. A larger area of light radiation can reduce the amount of module used, while a shorter word wall increases the brightness of the font. The organic combination of the two follows the law of conservation of energy and also reflects the importance of choosing the right LED.
It is worth noting that in the process of using LED lighting modules, we must pay attention to the voltage drop problem. Don't just make a loop, from the first to the end. This will not only cause the brightness to be inconsistent between the first and the last due to the difference in voltage, but also cause a problem that the single circuit current is too large to burn the circuit board. The correct approach is to connect as many circuits as possible to ensure proper voltage and current distribution. In addition, if you need to use anti-corrosion materials inside the word cavity, it is best to use a white primer to increase its reflection coefficient.
The application of LED in ultra-thin signs is based on the use of ultra-thin luminous signs to improve the utilization of business premises. In the past, ultra-thin light-emitting signs and ultra-thin light boxes have a thickness of approximately 1.5-3.0 cm. In 2004, based on this, an ultra-thin sign with a thickness between 0.8 and 1.5 cm was independently developed. The product uses a variety of technologies such as light guide, injection molding, engraving, and backlight. It is characterized by a smooth surface, no engraving and embossing, and uniform illumination without string light. The layout can be made infinitely large, small to the department card, and the road signs for the highway can be made. This ultra-thin signage can be selected according to the thickness of the customer and the size of the layout. Ultra-thin light-emitting sign with thickness less than 8mm and area below 450cm2, optional patch light-emitting module; ultra-thin light-emitting sign with thickness between 8mm-10mm and area between 500cm2-400cm2, pixel tube lighting module For large-scale ultra-thin luminous signs with a thickness of 10mm or more, super-high-lighting modules with a luminous angle of 30 degrees or less should be selected.
In short, when the majority of advertising industry colleagues use LED application technology to make products from led display factory, in addition to considering the stability of LEDs, it is also necessary to determine the LED illumination angle according to the requirements of the product, whether the brightness and the wavelength between the tube and the tube are allowed. Within the scope. Only reasonable choice of LEDs of different specifications can ensure that the product quality is up to standard, and at the same time, the production cost is minimized. Scenario LED overall lighting system and its characteristics Energy conservation and environmental protection are the social issues of universal concern in the world today, and directly affect the sustainable development of human society. For the lighting industry that directly consumes energy, it is more desirable to achieve energy-saving green lighting. The birth of semiconductor green lighting source has been hailed as a revolution in the field of lighting. Its symbol is that semiconductor light-emitting diodes (LEDs) have gradually entered the general lighting market as a new type of light source from the special lighting market, and the market prospect is extremely broad. As a special lighting source, white LEDs have shown tremendous performance advantages, strong growth momentum and rapidly growing market demand. In the next five years, LED lights are likely to become the mainstream of next-generation lighting.
Now LED products are complete, with outdoor full color display P16 (3906 points / square meter), P20 (2500 points / square meter), P22 (2066 points / square meter), P25 (1600 points / square meter); indoor full color display P6 (27700 points / square meter), P7.62 (17200 points / square meter), P8 (15625 points / square meter) P10 (10000 points / square meter) and outdoor, indoor monochrome, dual-primary display and many other models of display. It can also serve as a new carrier of advertising and is indispensable for the development of the advertising industry in the future.
[Edit this paragraph] LED display classification
1, according to the color base color can be divided into:
Single primary color display: single color (red or green).
Dual primary color display: red and green dual primary colors, 256 levels of gray, can display 65,536 colors.
Full color display: red, green, and blue primary colors, 256-level grayscale full-color display can display more than 16 million colors.
2, according to the display device classification:
LED digital display: The display device is a 7-segment digital tube, which is suitable for making clock screens, interest rate screens, etc., and displaying digital electronic displays.
LED dot matrix graphic display: The display device is a dot matrix display module composed of a plurality of uniformly arranged light emitting diodes, which is suitable for playing text and image information.
3. Classified by use occasion:
Indoor display: The light-emitting point is small, generally Φ3mm--Φ8mm, and the display area is generally several to ten square meters.
Outdoor display: The area is generally tens of square meters to several hundred square meters, high brightness, can work in the sun, with wind, rain and water resistance.
4, according to the diameter of the luminous point classification:
Indoor screen: Φ3mm, Φ3.75mm, Φ5mm,
