5050 lamp beads refer to lamp beads with a patch -type LED specification of 5.0*5.0mm. To put it bluntly, 2835 lamp beads refer to lamp beads with a patch type specification of 2.8*3.5cm. These two are also the most common in the market in the market. One of the model specifications of LED lamp beads. Many friends are doubtful, which one of 5050 lamp beads and 2835 lamp beads is higher? What are the differences in each? Click on the home page of the product: 5050 lamp bead products homepage. Customized LED color temperature: 1700-25000K365-850Nm can customize stream values: 20-35LM lingering value: 20-35LM/50-70lm/120-160LM working voltage: 3.0-3.4V working voltage: 3.0-3.4V output power: 0.2W output power: 0.2W/0.5W/1W Apart from the specifications of 5050 lamp beads and 2835 lamp beads that everyone mentioned earlier, 5050 lamp beads generally use three 0.02W integrated IC series to be encapsulated. The total output power is 0.2 W. The chroma is 20-26lm. Naturally, you can also choose an integrated IC with a higher nude crystal. The 2835 lamp bead generally uses a single-integrated circuit chip. The output power is 0.2W and it is 0.5W and its 1W. The same is the integrated IC of 0.2W. Select an integrated IC with a higher crystal clearness to ensure many different files such as 26-28lm/28-30lm/30-32lm/32-35LM. 2835 Lighting Display is thinner than 5050 because the support frame is thinner than 5050, and the single -integrated circuit chip is selected. Therefore, the relatively centralized lamp sources are concentrated. Because of the small body shape, the design scheme is more spiritual. For example, LED lamp tube, LED corn lamps, ceiling lights, ceiling lights. 5050 lamp beads are a printed LED with a long history. The key is used for LED light strips, guardrail pipes, touches, door advertisements and other LED products. Because of the characteristics of 5050 lamp beads, they can pack RGB three -color lamp beads. Therefore, 5050 is also a model specification for packaging 5050 wonderful RGB lamp beads. All in all, 5050 lamp beads and 2835 lamp beads are one of the very hot and very hot patch LED lamp beads. They have separate functional characteristics. Under the same output power, the chroma under the same output power condition, the color nature The foundation is similar, but it has different advantages, which integrates different main uses

1. AC -free LED is not the essential change of the device. In other words, there is actually no LED chip that does not have the working mechanism of AC Electric Farm. The AC -free LED that is now available is a specially arranged device in the internal chipset. It is just a change in the internal structure of the LED device. Of course The level of craft is not easy. The introduction of AC -free LED is mostly quoted information published by Seoul Semiconductor. It can be seen that it is a traditional rectifier bridge circuit to solve the problem of communication on the so -called DC LED power supply problem. It seems that the benefit is that the rectifier diode is eliminated, but the reverse resistance of LED is limited. When the grid is in a large peak, it is not necessarily the benefit. Because it is an imitation of the rectifier bridge circuit, only half of the current flows on the four bridge arm, and the DC load flows through the entire current, resulting in the current distribution of the upload of LEDs in each group. And light emitting efficiency, such as overcurrent to cause light decay and affect life. It is simple to solve. Just short -circuit the DC LED is removed. Take a closer look at the circuit, and now it has become positive and reverse LEDs in each group. In fact, you don't have to be too complicated at first. 2. AC -free LED does not avoid the essential constant current control technology. From the introduction, the light effect of AC LED is not higher enough than the usual LED. It is said to be the development stage. The author believes that the foundation of similar LED chips itself is the same. The main thing to restrict the amount of light per tile is the circuit type of the rectifier bridge. Imagine that only one group of LEDs can work normally, giving full play to the light effect, and 80%of the remaining four groups work in the underwriting state with poor light effects. No matter how to develop with it, it is naturally lower than that of ordinary LED's luminous efficiency. The way to improve is to abandon the unreasonable rectification bridge road. There is no constant current protection function in the AC -free LED. When used, it must be connected to the flow resistance. However, when the current at the limit of the power supply voltage is limited, it is necessary to work in the low light effect state of the underlying current when normal or low voltage. The resistance limit is a poor protection method. It not only has defects, but also rely on energy consumption to work, so that the utilization rate of power is reduced. If you want to add a PTC to solve the LED constant current problem, you don't know enough about the performance of the component. PTC is mainly used in overcurrent protection and thermal protection. When the current in the circuit is too large, when the PTC reaches the temperature of the residence after the heat, the resistance value rises sharply to the disconnection. The elimination circuit in the color TV uses it to generate a large current attenuation vapor. Demagnetic. When the PTC resistor is affected by the surrounding heat, the temperature will be opened when the temperature becomes more than the residential point, which can play a role in switching thermal protection. If you want to rely on the positive temperature coefficient characteristics of the PTC resistance to the LED's constant current protection effect: First, the PTC resistance passes the current, there is a heating time process to get hot. The current has already damaged LED. Second, the spontaneous heating temperature of the PTC resistor can really control the constant current. Then the impact of high environmental temperature and low may change dozens of degrees to make this "constant stream value" change meaningless. Is it possible that the common LED devices can also be so simple to flow at the current simple current? Unfortunately. And usually communication constant flow is more troublesome than DC constant current. In fact, there can be all kinds of high quality Product support. Instead of energy, LED manufacturers will be more energetic in terms of circuit technology, and it is better to focus on developing low -cost and high -light LED lighting products.

Many friends see that they are amazed by modern new LED lamps such as crystal chandeliers and such as fashionable LED lamps, so how are these colorful crystal chandeliers who look like fireworks?. Also, in life, we often see the LED lamps on the TV, the owner of the lamp company and the engineering designer cleverly developed design, and through the combination design, these colorful lamps are produced. LED products are more into commercial lighting and home lighting, so when many friends take the full map of these LED lamps with their mobile phones or cameras, I often ask Tianhui. The LED lamp beads form such a stylish lamp. Especially recently, many new LED series crystal lamp series appeared in many home furnishing markets. Small white light LED lamp beads are combined with crystal sequins, which forms silver multi -layer crystal lamps to combine many small LED lamp beads to combine the combination to combine Make us amazing artwork. For example, the bright star -like top lamps, these lighting design is simple, and it looks as bright and gorgeous as traditional crystal lamps. As for the top lights that bloom -like effects of fireworks, it also breaks through the design pattern of traditional LED ceiling lights in the market. Let's be amazed by the creativity of the designer. But, friends, do you know, these exquisite design lamps, its main materials are composed of small LED lamp beads. There is also the coincidental silver multi -layer crystal desk lamp, which is also made of small white lamp beads with crystal sequins. At the same time, in daily life, more exquisite night lights, exquisite table lamps, multi -angle U -shaped lamps, etc. are composed of small LED lamp beads, just choose different lamp beads, different ones, different ones, different ones LED lamp beads are selected and designed, how?

The UVLED tester has been used in all walks of life. The intensity of light is the most important indicator of UVLED. Below we introduce two testers commonly used by Tianhui. 1. The UIT-250 of the USHIO ox tail in Japan is shown in the figure below. The tester is a optical power of the 365nm wavelength. It can test the instant value and peak value. high. 2 LS128 UV tester is shown in the figure below. The wavelength that LS128 can test is relatively wide. 340nm-420nm wavelength can be tested. The back is a light sensor. It also tests 3 parameters, power, energy, and temperature. The accuracy of the test value is not high.

The output power control of the UVLED curing machine is an important parameter of the device. It directly determines the effect of solidification. On different occasions, the intensity of light required is different. Therefore Different power, we use the products of Zhuhai Tianhua Electronic Co., as an example to illustrate how to achieve different power output. First of all, there is an interactive interface to control the software. You can set the external input conditions from 10%to 100%. When an external input is input a certain value, the system will generate a DA signal. Accepting the constant current source of the light source, the power supply will provide the corresponding power to the light source according to the requirements, control the light source, and the operation is simple and convenient.
