This section mainly introduces the core components and assembly process of LED energy-saving lamps and LED corn lamps, and conducts in-depth discussions on the common one-stop LED energy-saving lamps for the RC capacitors.
1. First understand the theoretical working principle of LED energy-saving lamps. There are two kinds of LED energy-saving lamps on the market. The first one is low-power in-line lamp beads. LED light sources (such as LED corn lamps are more common) driven by traditional RC-capacitor circuits are driven. The working principle of the information online a lot, you can find in Baidu search "resistive capacity buck power circuit", this kind of driving is uneven, the advantages and disadvantages are mixed, if 230V input, 2.5W ordinary LED energy-saving lamps , using a reflector lamp with a 3014 lamp bead. It can be certified by CE, and the sales are oriented to Europe. The cost is mainly the cost of the lamp and the shell, and the driving cost is a few cents to 1 yuan. The other is to use the power IC chip, mainly constant current or constant voltage, but most of them are using constant current, easy to do, but as far as I know, constant pressure should be better than constant current. However, it is more difficult to debug. The working principle is to convert the input of the AC and finally output a stable DC output to drive the LED. The other is LED energy-saving lamps designed with wide voltage, using constant current drive, like LED energy-saving lamps, when using aluminum substrates and patch light sources, the market is a penny SNYFQ this brand of LED energy-saving lamps (Suo can produce) It is the production process of aluminum substrate and patch, this article does not go deep, leaving a second time to make a detailed solution. To understand this, we must go deep into the following points.

2, assembly LED energy-saving lamp components: single to say the components, the resistance to the buck of several components: capacitors, resistors, electrolysis, some plus a triode and MOS tube. In the case of the chip, the core is the power IC chip, followed by the transformer, electrolysis, optocoupler feedback circuit, and then according to different chips, the front edge or the output, the feedback part adds some devices, no more than diodes, capacitors, etc.
3, the assembly tool is very simple: the production line of the drive power, is the plug-in, you can also go to the lamp to buy the driver; the whole lamp assembly wire (electric soldering iron, electric batch, etc.), make a small workbench. It is ok to go to the city to purchase the materials. If there are conditions, design the drawings to open the mold, so the cost is more advantageous, but the general amount is only to do so.
4, the process of LED energy-saving lamps is difficult to say bit by bit: in a nutshell, mainly plug-in, immersion tin, cutting feet, testing, assembly, aging, packaging. The homework book can be taken on the line by yourself, mainly indicating the items that need attention and the operation essentials for each process.
5. Cost composition: material cost, labor cost, management cost, auxiliary material cost, and utility cost. Some have to add equipment depreciation, etc., and materials must also consider certain wear and tear.
6, LED is now maturing, there are better solutions for the problem of heat and brightness, these mainly depends on the design of your engineer, if you do not solve the heating problem, then the LED finished lamp is very easy to appear Light decay problem. National policies should also promote the use of LEDs. Otherwise, street lights should be replaced by LED street lights. If you pay attention to them, you can see that many cities have replaced LED street lights.
7, the assembly mode, is the current workshop, the main cost is the initial investment, this depends on your specific ideas, if you only assemble, that is the investment of the workbench, the necessary assembly tools, if you plan to If you develop, design, and produce, there are a lot of instruments and equipment that you need to buy. The investment is big, but I think your plant area is not big. It is recommended to start with assembly. You can create a production model or build your own brand of LED energy-saving lamps.
