Often heard that now the LED lamps and lanterns is short life is mainly the power of life is short, and the power are shorter because electrolytic capacitor
They also have a point.
Inferior because there has been a lot of short life of electrolytic capacitor
s, plus spell the price now, so some factories without regard to the quality of short life of these poor electrolytic capacitor, the result is the conclusion.
At present, has many first-class brand both at home and abroad to achieve long-term, stable relations of cooperation.
Today, let us share a multiple disassembly process LED lights.
LED energy-saving lamps: the characteristics of low cost, high photosynthetic efficiency, luminous area is large, no glare, no ghosting.
LED bulbs is using high brightness white LED light source, high luminous efficiency, less power consumption, long life, easy to control, free maintenance, safety and environmental protection.
Semiconductor chip consists of two parts, one part is a p-type semiconductor, dominated by holes in it, the other end is n-type semiconductor, here is mainly electronic.
When a current flows through a wire to the chip, the electron will be pushed P area, electron and holes in the P zone compound, then will be issued in the form of photon energy, this is the principle of LED.
Because the LED lamp calorific value is not high, the electric energy into light energy as much as possible, and the ordinary lamp by the many electrical energy turns into heat energy, heat wasted.
In contrast, LED lighting is energy saving.
Materials to prepare 1, LED energy-saving lamp 1, 2, 3 screwdriver, soldering iron, etc. Second, the disassembly process to share first open the LED light lamp shade, you can see a large piece of aluminum plate, which has an LED circuit control board, the power input for the spiral mouth 220 v socket: leds luminous surface, three parallel 43 group series, after the above 3 * 43 groups LED lamp bead in concentric circles of uniform distribution, the LED lamp board and control board welding connection, between the two is negative, the other two are aided fixation: LED panel: : the main control chip of 7 pin pin close-up view to the wafer model LED on the back panel, the PCB for single-sided printing electricity board, with electric heating separate control panel with aluminum plate welds: control panel connected to the above four points using straight needle welding: tear open come down to the control panel on the back of: can see clear components: 【
Life index of the electrolytic capacitor has a characteristic, how many degrees is must in the life of the working environment temperature circumstances.
The higher the temperature, the easier it is to electrolyte evaporation.
So the service life of electrolytic capacitor index must indicate what is in the life of the ambient temperature.
,难保不是说一千小时以后这个电解电容就坏了而只是说这个电解电容的容量在1000小时以后小容量减少了分书来是20 uf,目前有10 uf的了。
At present, ShenMao electronics with high temperature resistance (
Shenzhen Shen MaoXin Electronics Co., Ltd. is a gaint manufacturer of electrolytic capacitor, which is one of the most outstanding product produced from us.
Shenzhen Shen MaoXin Electronics Co., Ltd. offers the best products, high-quality services and innovative technology.
Consistency and simplicity go hand in hand. That means aligning Shenmao with the right platforms, speaking to the right customers with the right message, and selling the right idea.
Consumers like these are interested not just in electrolytic capacitor they will spend their money on, but also in the human and environmental impact of the supply chain that produces those goods.
electrolytic capacitor suppliers electrolytic capacitor is characterized by various advantages, such as electrolytic capacitor suppliers, electrolytic capacitor suppliers and electrolytic capacitor suppliers, which is not the case with other electrolytic capacitor.
