At present, the application of LED flat lights in indoor lighting is more and more extensive, whether it is a hotel, conference room, factory or office, commercial use, residential or public facilities, schools, hospitals, as long as there is energy saving or need high color rendering most of the places have used LED flat lights to replace traditional fluorescent lamps, on the one hand, LED flat lights have played a role in energy saving and environmental protection, On the other hand, it creates a good lighting atmosphere. That its internal structure in the end is what it looks like, generally speaking from a large aspect, we divided an LED flat light into seven components, below we will understand the seven parts in detail!

1, Aluminum frame: aluminum frame appearance structure composition and LED heat dissipation main structure generally use AL6063, aluminum extrusion die, the early cost investment is low, the surface treatment is beautiful, the heat dissipation effect is good, but if the use of die casting frame, this can not only improve the IP protection level, and the sealing light is better, the overall appearance, but the early investment mold cost is higher.

2, Light guide plate: the side LED light through the dot refraction to change the Angle of light out, light guide plate is the heart of the flat lamp, dot design is very important, dot design is not good, see the overall light efficiency is very poor, generally appear :1.  Light in the middle, dark on both sides;  2.  There is a bright edge in the light, and the middle is dark;  3.  Standing at different angles, the overall brightness is inconsistent;  4.  Local dark areas are obvious.  A large part of the light efficiency of the light guide plate is in the design of the network, followed by the selection of plates, but the blind pursuit of brand plates is not right, because many brand manufacturers like Japan's Mitsubishi, most of its good plates are ordered by people, many of the market out of Mitsubishi plates are more than scrap material, its low light transmittances are not as high as their own plates.  Therefore, the selection of the plate does not necessarily depend on the manufacturer of the plate, as long as the test of high light transmittance is OK.

3. Diffusion plate: the role of diffusion plate is to evenly disperse the light of the light guide plate, and play a role in blocking the dot, diffusion plate generally uses acrylic sheet or PS material, acrylic cost is low and light transmittance is slightly higher than PC, acrylic brittle anti-aging performance is weak, PS price is slightly expensive, but anti-aging performance is strong. After the diffusion plate is installed, the dot cannot be seen, and the transmittance should be about 90%. The light transmittance of acrylic is 92%, and PS is 88%. We can choose the diffusion plate material according to the demand, and acrylic materials are generally used.

4. Reflective paper: Reflective paper mainly reflects the light behind the light guide plate, generally RW250.

5.LED light source: Generally use SMD3528, some people use 5630 and 5050, 5630 and 5050 light efficiency is not high and network design is difficult, poor versatility, but low cost. The SMD3528 has high optical efficiency and strong versatility.

6. Back cover: sealed lamp body - generally AL aluminum, the overall texture is strong, and can play a little heat dissipation role.

7. Drive power supply: At present, LED lights have two power supply modes: 1. Direct use of constant current power supply (this mode has high efficiency, PF value up to 0.95, cost-effective); 2. Constant voltage with constant current mode (stable performance, but low efficiency, high cost). Generally, this mode is designed for customers who require certification, because the lamp is a low-voltage lamp with 24V input, there is no need to do safety regulations, and the direct use of the power supply with safety regulations can be shipped to various countries, with a wide range of use.

LED line light style dazzling, many manufacturers recommend their own line lights made of good quality, low price, long life, etc., there are some expensive "brand goods", in the end how we want to distinguish the quality of line lights.


First, look at aluminum:

Ultra-thin aluminum is changeable, in the aluminum selection of line lights, regular manufacturers will first consider the heat dissipation performance is good, do you think that the thicker the aluminum, the better? Aluminum if you want to do not easy deformation, good heat dissipation, you must choose a moderate thickness, you can not say that you want the thicker the aluminum the better, in addition, if the thinner the aluminum of the line lamp is not the better the heat dissipation? The thinner the aluminum, the worse the heat dissipation, and the easier it is to squeeze and deform during installation, so it is not necessary to cut corners! Another is a cost-effective problem, if you want to be cost-effective, manufacturers must control the material is quite good.

Second, look at the selection of circuit boards:

Is aluminum substrate definitely better than fiberglass? Really good quality line lights, most of the use of aluminum substrate as a light source circuit board. Is fiberglass always labeled as inferior? Glass fiber board is also good or bad, and even better than the quality of aluminum substrate, as long as the stable play, whether it is aluminum substrate or glass fiber board, they are good circuit boards.

Third, look at the glue:

LED line lights in 1 year after the serious yellowing phenomenon is because the glue material is too poor, there are a lot of inferior glue on the market in the name of waterproof PU glue to sell, poor waterproof performance, easy to yellow and dark, the same with the normal waterproof PU glue price is very far apart, basically more than double the price difference.

Four, look at the waterproof plug:

LED market is really large, every year, customers will consult once: "Is there a new price this year", some manufacturers are forced by this pressure, will reduce a little in the material, but there are also some manufacturers to lower the profit to maintain the original customers, waterproof plug is also cheap, but relatively bad conduction, there is poor waterproof performance, easy to water leakage, basically square four-core plug is also very good although its price is high, But the overall stability can reach 99% waterproof, that 1% May not be plugged tightly.

The two main groups of led high voltage lamp belts, namely LED and FPC, are not low temperature resistant products. If the FPC continues to remain cold or beyond its acceptable measurement range, it will tear the covering film of the FPC and indirectly form LED strip fragments. At the same time, leds cannot continuously withstand low temperatures. After working at low temperatures for a long time, her chips will burn out at low temperatures. Therefore, the soldering iron used in wholesale LED lamp strip maintenance must use a temperature-controlled soldering iron to limit the measurement range to one degree and prevent arbitrary changes and adjustments. However, in addition, it must be noted during maintenance that the soldering iron will not stop the LED pen from turning for more than 10 seconds. If more than a certain time, it may burn the LED chip.

led high voltage lamp with the choice of output light color: it should be said that everyone has their own hobbies, and they can not be the same. But I can give you some advice. Usually, ceilings are usually white and other light tones. The living room usually uses yellow and blue light depending on the purpose of the room. Yellow light gives people a warm and natural feeling, especially in the cold winter. To. Blue can make your room look bigger, deeper, and more meaningful. If you want to be festive, red is also a good choice. Other red and blue two-color output light strips, if equipped with a controller, will be more dynamic, you can experience a modern romantic atmosphere, haha, the restaurant should use yellow. Yellow is used in study rooms and children's rooms. A room with a better color.

In order to obtain the national energy saving grant for the led high voltage lamp belt, the company's hardware must first meet the following criteria: Laboratory, high education, product certificate and a number of invention patents. For example, if an energy-saving lamp is tested for mercury, the product must be tested to determine its mercury content. In order to conduct this test, large companies can set up rigorous laboratories to conduct the test. Secondly, it depends on whether the product quality and price are in line with the market. Only companies with high-volume production have a greater chance of reducing product prices, while companies with small-batch production have greater difficulties. At the same time, the degree of modernization of large companies has been significantly improved, there are fewer human factors in product production, and product quality has been greatly guaranteed.

With the continuous development of society, ordinary people are becoming more and more aware of environmental protection and energy saving, so the demand for LED lighting products and quality requirements are becoming higher and higher. With the popularity of LED light strips, LED line lights, LED flat lights and other lighting products, LED light strips, LED light strips have been widely used in furniture, automobiles, advertising, lighting, ships and other industries.

More and more large shopping malls and supermarket buildings are decorated with LED light strips, which emit a gorgeous glow at night, so that we can enjoy the beautiful scenery and feel happy. But sometimes, the LED light belt is used for a long time, and there will be more and more dark or not bright, then the LED light is not bright, what are the reasons? Today I will explain to you:

one Transportation damage: The packaging protection of the LED lamp strip is imperfect, resulting in damage to the internal lamp beads during transportation. Or appear, the welding point of the LED lamp strip has a virtual welding phenomenon, and the vibration during the transportation causes the welding point to fall off, resulting in the lamp strip is not bright.

2. Process defects: LED lamp solder amount is small, the solder joint is easy to fall off. Or the solder quality of the LED lamp strip is not good, and the solder joint of the LED flexible lamp strip is easy to crack and fall off during the bending process. The welding resistance layer of the lamp strip circuit board is too thick, and the solder and the circuit board can not be completely fused together during welding, which is also a virtual welding phenomenon.

3. Lmproper installation: When the LED light strip is installed, the bending Angle is too large, resulting in the separation of the solder joint of the LED flexible light strip and the copper foil. If the product is excessively squeezed during installation, the LED flexible lamp strip chip is damaged or the solder joint is deformed and falls off. Therefore, the user is especially reminded that it can not be twisted during installation, so as to avoid the solder joint falling off and causing no light.

Therefore, the above problems need to be avoided when selecting LED lights, so as to ensure better quality and longer service life of LED lights.

Features of the LED driver power supply: high reliability, especially the LED street light driver power supply installed at a high height, with a waterproof aluminum housing power supply. If the quality is good, it is not easy to damage, and the number of maintenance is reduced. High performance LED is energy saving products, driving power performance is very high. The power supply structure in the lamp is particularly important. Since the light output of the LED decreases with the temperature of the LED, the heat dissipation of the led engineering lamp belt is very important. The performance of the power supply is high, the power consumption is low and the heat generated in the lamp is low, thus reducing the temperature rise of the lamp. Delayed LED light attenuation is advantageous. High power factor The power factor is the load requirement of the grid.

One of the main features of the led engineering strip is the increase of the flexible patch strip from the original 12 V to 220 V, and the need to use a transformer to make the strip unconstrained by the transformer. During installation and use, it can be connected from 10 to 50 meters respectively. This is more advantageous than the original installation of 12 meters long 5 meters of flexible patch lights.

There will always be revolutionary technologies. The self-lighting wall no longer participates in the game of hiding the light source, and countless leds are hidden behind the translucent wall. The promise of this technology is difficult to evaluate because not only can it dynamically change different colors, textures, and brightness to simulate any type of texture, but it can also be combined with audiovisual technology to become an interactive medium. Perhaps lights and walls in buildings in the future will no longer be static units, but will change or contain a lot of information, and even contain a "spatial presence" that can change style as people move. This will completely change people's understanding of architectural space. The iPhone, for example, changed people's understanding of what a mobile phone is.

LED soft light strip has a service life of up to 30,000 to 50,000 hours when it is used normally, so it is favored by mass users. However, any electronic products can not rule out individual cases of poor electrical performance. So sometimes you will hear netizens say that their home LED soft light strip is not bright, after the problem is convenient for everyone to investigate and solve the problem. Here to teach you a few simple maintenance methods of LED soft light strips, so that similar problems can be quickly solved in the future.

Problem 1: The LED soft light bar is not on. LED soft light strip is not bright can be divided into two cases: one is the whole is not bright, the other is part is not bright. The former reason may be caused by the power failure caused by the plug falling off, check that the plug is firmly inserted, if the power failure is excluded, it is necessary to consider replacing the new drive debugging, which can generally be solved.

The second kind of problem is more common, the main reasons for this failure are: 1, in the process of use may be affected by the impact of the LED soft light strip, 2, because the voltage instability or local high voltage overload causes the internal led chip to burn out. After cutting off the power supply, cut off the part that is not bright, and then prepare a two-way interface plug to plug in both ends.

Problem 2: LED light belt in the intelligent dimming system, the luminous color can not be switched at will. With the rapid development of the LED industry, intelligence and dimming have become the main choice at present. Dazzling and romantic lighting into the modern home, but also add to the warm atmosphere. However, in use, occasionally you will find that the LED soft light strip at home can not switch lights, at this time to find the reason is the key, generally may be a problem with the regulator, carefully check to see whether the interface is not strong or the regulator is broken, if it is the interface problem plug some can be, if the regulator is broken, it is necessary to replace.

LED light belt installation precautions:

1. LED soft light strip products are DC DC12V~24V, please connect 12V/24 low voltage or purchase transformer switching power supply;

2, When installing, clean the surface of the object, tear the double-sided adhesive on the back of the product and press tightly;

3, RGB full color series, please purchase matching RGB controller for remote control color (24 keys /44 keys; You can set monochrome/all-white or remote gradient, jump and change the color change speed...) ;

4, When the product is used routinely, it is recommended to parallel; When used in series, the connection length should not exceed 5 meters, so as to avoid uneven luminance caused by lamp strip pressure drop.
