Szczegółowe wyjaśnienie trzech głównych metod rozpraszania ciepła z diod LED

Like all electrical products, LED lights generate heat during use, causing an increase in ambient temperature and temperature. coque iphone 7 stitch bleu cover custodia case iphone 11 B8377 code vein wallpaper 11oZ8 The led light bar is energy efficient. remise nike cover custodia case iphone 11 O1355 razer wallpaper 52mE4 Ultra-bright high-power LED light source, combined with high-efficiency power supply, saves more than 80% of electricity compared with traditional incandescent lamps, and the brightness is 10 times that of incandescent lamps under the same power. coque d’airpods stitch The long life is more than 50,000 godziny, which is more than 50 times that of traditional tungsten lamps. dragon ball super caulifla coque iphone 11 The LED uses a highly reliable and advanced packaging processeutectic soldering to fully guarantee the long life of the LED. coque téléphone huawei y5 2019 stitch amylee custodia iphone x tyui7121 The luminous efficiency can be as high as 80lm/w, and the color temperature of various LED lamps can be selected, the color rendering index is high, and the color rendering property is good. cover iphone 11 sky night Led light string led technology is advancing with each passing day, its luminous efficiency is making amazing breakthroughs, and prices are constantly decreasing. nike air max The era of a white LED entering the home is coming quickly. nike officiel fjallraven kanken classic backpack plum Custodia Cover iphone 11 pro max boruto uzumaki X00047 Case Impact resistant, strong lightning resistance, no ultraviolet (UV) and infrared (IR) radiation. Custodia Cover iphone 11 pro max levi attack on titan Z3646 Case No filament and glass casing, no traditional lamp tube fragmentation problem, no harm to the human body, no radiation. A solar-powered light-emitting diode is a solid-state semiconductor device that converts electrical energy into visible light, which converts electricity directly into light. brick fjallraven kanken backpack mini The heart of the LED is a semiconductor wafer with one end attached to a holder, one end being the negative pole and the other end connected to the positive pole of the power supply, so that the entire wafer is encapsulated by epoxy. cover custodia case iphone 11 Q9352 tanjiro wallpaper 65wC8 If the heat dissipation problem is ignored, it will not only affect the service life of the LED lamp, but also burn the LED lamp. black and ox red fjallraven kanken backpack classic Custodia Cover iphone 11 pro max Dogs like teacher O7442 Case At the same time, it also affects the normal growth of irradiated plants. Custodia Cover iphone 11 pro max no game no life shiro render Z1645 Case W związku z tym, heat dissipation is a very important part in the manufacturing process of LED lamps. LED lamps mainly use the following cooling measures (1) Plant lamp fan heat dissipation: The principle of using a fan to output the heat generated by the LED lamp into the air is very simple. Just like the cooling principle of a computer and a TV set used every day, air convection occurs through a fan to ensure that the temperature of the air around the heating element is not too high. metalocalypse custodia iphone x tyui10413 Simply put, the fan is used to send the hot air generated by the LED lamp to the air, and then supplemented with room temperature air to achieve the heat dissipation effect. (2) Natural heat dissipation: Natural heat dissipation means working directly in the LED lamp without external measures. nike dernières coque samsung s9 plus stitch The main principle is to make the whole lamp of the LED lamp have a large contact area with air, and use components with better thermal conductivity. cover custodia case iphone 11 E0534 umineko wallpaper 66hX8 In order to better transfer the heat generated by the luminaire to the air, and then through natural convection, that is, the hot air rises, the cold air compensates, thereby achieving the purpose of heat dissipation of the LED lamp. coque iphone 6 supreme Led radiator The heat sink mainly uses a heat sink, a lamp shell, a system circuit board, itp., and the cost thereof is relatively low, and the heat dissipation effect is also good, and is widely used in various electrical equipment. ox red and royal blue fjallraven kanken backpack mini (3) Electromagnetic heat dissipation: Electromagnetic heat dissipation is called electromagnetic jet heat dissipation. Instead of using a fan for gas convection, electromagnetic vibration is used to drive the vibration of the film cavity to make the air circulate and flow, achieving the effect of heat dissipation. The technical difficulty is complicated. Some LED products are used. fjallraven kanken kids backpack un blue Temperature can change the physical form and chemical structure of an object, some are better, such as cooking and cooking, while others are not good, such as burns and burning. When using LED lights, we don’t want it to generate so much heat. coque s20 fe stitch black veil brides custodia iphone mini pro max 12 ret11689 Custodia Cover iphone 11 pro max Chicago Cubs X9267 Case In addition to improving the efficiency of electro-optic conversion, only heat dissipation measures can be added.
