Detailed explanation of panel light technology - how to choose cheap and high quality flat panel

A few days ago, I met a customer who asked me a question. She said that the flat lights look similar. How do I know which one is the best? At that time, the situation was quite sudden and I didn't think deeply. Afterwards, I felt that this problem really deserves our deep thought. When customers face the market's dazzling array of products, how can they distinguish which one is the best quality product? How can we let our customers know that our products are the best? Let's take a step-by-step anatomy of the panel light to help you choose a cheap and high quality flat panel light! Then we need to understand the main cost of the flat lamp. In which aspect 1 light guide plate, now there are many kinds of light guide plates, there are silk screen, laser dot, V groove, polymer light plate, thickness is also very variety 3mm, 4mm, 6mm, 8mm, different thickness, different types, different prices of plates are also different, but the flat lamp core is on the light guide plate, then what kind of light guide is good? Personally, the light guide plate is mainly a light guiding function, as long as the light guiding efficiency is high, the uniform illumination is high, and the phenomenon of yellowing and blistering does not occur for a long time of lighting, and the others are floating clouds. At present, the light-guided light guide plate has the highest light guiding efficiency and the best effect, but the price is also the most expensive in these categories! - The price difference varies from 5-15 yuan. The thicker the thickness of the sheet, the higher the illuminance. Now there are more 4mm light guide plates on the market, because the price of 4mm and 6mm plates is about 20-30 yuan. Therefore, on the light guide plate, you must know the type of flat light guide plate and the thickness of the plate material manufacturer and thickness. The light guide plate is relatively high in this piece of water, and the price of the poor light guide plate is about 30 yuan! 2 drive power, this is the main component that directly affects the energy efficiency and life of the flat lamp. The front panel lamps are constant voltage with constant current to drive the panel light. This method has low efficiency, low power factor and high cost. Now it is gradually eliminated. Personally, if you see the tablet driven by this method. The lamp is recommended to be changed to a direct constant current flat panel light! (Individuals are engaged in structure, the cost analysis of the power supply may not be unique enough, you can make a brick for the power hero! But don't pat the face) It is well known that Ming Wei power is the most cattle, the price is also high, but its Stability is also relatively good. For our users, the following points must be considered when looking at the power supply: 1. The efficiency of the power supply (this is directly affecting the energy efficiency of the luminaire, and also whether the power supply is well designed) 2. Whether it has a PF value (with PF and no The power supply price of PF value also varies greatly. 3. Power transformer temperature (this directly affects the life of the power supply. Generally, it is filled with aluminum shell power, the heat dissipation is better, the stability is higher, but the price is quite different) 4, Is there any certification (power supply some electrical parameters we do not understand, there is no instrument testing, mainly to see if there is any certification, so you can understand whether a power supply can pass the safety performance, CE certification is a must, there is UL certification It is relatively expensive, but the quality is better in all aspects.) The price of the power supply is also uneven, and the price difference is also very far. The power supply with low price like Zhongshan is a solution for people to copy, and then paste it. Domestic electronic components, or recycled materials, do a good job and then label them, what certification marks are there, and then the actual certificate is not, Compared with the ordinary power supply price of 20-40 yuan, the quality of after-sales is not guaranteed 3LED lights, now the competition in the lamp market has entered a fever, the price war continues, domestic packaging companies are trying to reduce costs, the materials are It is getting worse and worse. I still recommend using imported lamp beads to ensure that the domestic market is too chaotic. The price of lamp beads is from a few points to 1 hair 2 hairs. The price of lamp beads is too high, and the test time period is relatively long. The loss will not be recovered, and the number of LEDs used in panel lights is relatively large. The price difference is 1 point, 2 points, and the overall cost price is also very different. For 5630, the domestic general price is around 2-3 hair. The price of a Samsung lamp is about 5 hairs. The price of a flat lamp is about 18 yuan. 4 diffused plates. The main materials are PC, PMMA, PS, PP composite materials. Please refer to the current stage for the comparison of materials. Most of the flat-panel lamps use PS materials, and a small amount of other materials are used. The price of PC is relatively expensive. It is PMMA, then PS, and then PP. The price difference here also ranges from 5-20 yuan to 5 frame profiles. Other components, the frame material is generally 6063 or 6061, the price difference is small, mainly depends on the cross-sectional area of ​​the designed frame, the cross-section is small, the material reduction price is relatively low, and the price difference of the frame is generally also 1-3 yuan. Not waiting. Followed by the rear cover, the thickness of the rear cover is not the same, the commonly used is generally 0.8 thickness and 1.0 thickness, and now there is also the use of iron bottom plate, the price difference is also a few dollars or so 6 manufacturers of professionalism, "The Wealth of Nations" tells us that a product can only effectively reduce the cost of a product if it is mass-produced, and the professional level and shipment volume of a manufacturer will save us the cost in disguise. The professional manufacturer In terms of production technology, since employees are repeating a single job, practice makes perfect, and production technology is continuously improved to improve production efficiency, the labor cost of the flat lamp is reduced, and professional manufacturers are purchasing and preparing materials. It is also convenient, the purchase of materials is single, the purchase unit price can be greatly reduced, and the professional manufacturer, the reaction speed is also fast, the product performance is stable, the technical professional, the only way is to focus, so professional! You can also save 20-50 yuan on the price of flat lights! In the end, the price difference between a low-end flat panel light and a mid-to-high-end flat panel light is about 150 yuan, and even if it is a high-end product, the so-called price advantage is actually just a slight change of a certain accessory.
