Detailed explanation of the three main heat dissipation methods for LED lights
(1) Plant light fan heat dissipation: The principle of using the fan to output the heat generated by the LED lamp to the air is very simple. Just like the heat dissipation principle of computers and televisions used every day, air convection is generated through a fan to ensure that the air temperature around the heating element is not too high. Simply put, the hot air generated by the LED lamp is sent into the air with a fan, supplemented by room temperature air to achieve the heat dissipation effect.
(2) Natural heat dissipation: Natural heat dissipation refers to working directly inside the LED lamp without external measures. The main principle is to make the whole lamp of the LED lamp have a large contact area with the air, and the components with better thermal conductivity are used. In order to better transfer the heat generated by the lamp to the air, and then through natural convection, that is, hot air rises, cold air is compensated, so as to achieve the purpose of heat dissipation of LED lamps.
(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 membrane cavity to circulate air and achieve the effect of heat dissipation. The technical difficulty is complicated. Some LED products are used. Temperature can change the physical form and chemical structure of an object, some are better, such as steaming and cooking, and some are not, such as scalding and burning. When using LED lights, we don't want it to generate too much heat. In addition to improving the electro-optical conversion efficiency, only heat dissipation measures can be increased.
New Borui GE has finally arrived. The strength he has demonstrated can be said to be particularly strong. Not only that, it also has quite mature configurations. Regardless of which version, Borui GE has a good performance, so overall, the competitiveness of this car is still acceptable, and in terms of price, it is also known as the "people-friendly" new dark horse.
Recently, we obtained the configuration information of the Jetta VS5 model under the FAW Volkswagen Jetta Jetta brand from relevant channels. The new car is positioned as a compact SUV and will launch five models, namely 280TSI Manual Fashion, 280TSI Automatic Fashion, 280TSI Manual Comfort, 280TSI Automatic Comfort, and 280TSI Automatic Luxury. According to the information released this time, in terms of external configuration, the new car will be equipped with LED headlights/tail lights, roof luggage rack, 17 inch wheels, etc. The high-end models will also be equipped with automatic headlights, 18 inch wheels, electric sunroof, and welcome lighting.
Philips Professional Lighting recently successfully provided high-quality LED lighting solutions for the first phase of the National Exhibition and Convention Center (Tianjin). Help build a new generation of green, intelligent and innovative national convention and exhibition complexes. As one of Philips' suppliers, Jin Dingsheng provided 20,755 meters of 15*15 top view switch 4000K extruded silicone IP66 neon in this project. From June 6th to 24th, the new hall of the National Exhibition and Convention Center (Tianjin) ushered in the first exhibition.
