LED tube lights design development processon November 28th, 2011 at 2:02 AM
LED tube lights is now used by Shan Gu-shaped aluminum structure structure. But LED fluorescent beginning of the design is not the case. LED tube lights in the structure to go a lot of detours, the beginning is modeled on the appearance of fluorescent light manufacturing, and later gradually evolved into a fan-shaped bone aluminum design.
The development process of an LED lamp structure: plastic tube
LED tube lights as it is called the structure the appearance of some is fluorescent, and even the length, thickness is the same, even the call is T10, T8, T5, are also the same, there is no discussion of what can be. Therefore, the LED lamp is a replica of the early manufacture of fluorescent lamps. Is also modeled on the basis of a number of changes. Early LED tube lights is used in plastic, because the main use of non-isolated power supply to avoid electric shock problem, so hope that the use of plastic tubes. Which uses a straw hat φ5 tube LED. But soon proved that the fluorescent light decay is very serious, life expectancy is very short, less than 1000 hours on the bad. This discovery, fluorescent design the biggest problem is heat. Because all of the heat sealed in the pipe and can not spread it out, along with the short straw tube had life, naturally fluorescent lifetime shorter.
LED lamp structure of the development process of two: half plastic half-tubes
To improve heat dissipation LED lamp, production house thought of semi-plastic half-aluminum solution. In light of that half of the required plastic, light and need no heat in that half of the aluminum alloy. Power on the aluminum tubes inside. This seems to have light and heat have done it. However, because the power LED lamp usually 20W or so, its heat is still quite large. Half a tube and heat it can not solve the problem.
LED lamp structure of the development process of three: Shan Gu-shaped aluminum
Finally, the production house to the devised LED tube lights-shaped structure of a Shan Gu packaging. Put power into the tube, completely made of the aluminum radiator. Shan Gu-shaped aluminum structure using Shan Gu shape of the heat, greatly increasing the radiator area. Relative to the semi-circular aluminum tubes, it increases the cooling area of at least three times. Coupled power is not on the tube, but also can reduce the heat, which greatly extend the life of the LED lamp.
