Outdoor LED Lamps, can you cancel the drive?

2022-07-12

Nowadays, LED light source is widely used in outdoor lighting lamps. There is a very important component in the lamps, that is, the driver. There is no doubt about the importance of this driver to LED light source. Without it, outdoor LED lamps cannot be used. However, although the driver is very important, the price of the driver is not cheap, which is a major source of the cost of outdoor LED lampsfixtures; At the same time, the quality of some LED drivers is mixed, which is often an important reason for the unstable quality of lamp products.

Now the question comes, can we open a brain hole: cancel the LED driver? This can not only reduce the cost of outdoor LED lamps and lanterns, but also reduce the source of a major failure of LED lamps and lanterns. 

In fact, Xiaobian can think of this brain hole, which has long been thought of by big players in the industry, and some have been implemented years ago, but why are few manufacturers in the industry using drive free solutions? It turned out that it was found in the process of actual use that the cost of outdoor LED lamps was reduced, but the failure did not decrease, and most of the failures were caused by the direct burning out of the light source. Therefore, although the drive free scheme can effectively reduce the cost, few outdoor lighting manufacturers are willing to adopt the LED drive free scheme because of the high damage rate.

In fact, in the process of normal use, the service life of outdoor LED lamps fixtures is very long. The reason why the failure rate of early outdoor LED lighting fixtures without drivers is high, and the main reason for the direct burning of the light source lamp board is that the withstand voltage of LED light source is very low, and it can only withstand about 500 volts at most, so it can only be used when the voltage fluctuation range is small; However, outdoor lighting fixtures are used outdoors. In nature, an ordinary lightning strike will basically exceed the withstand voltage of the outdoor LED lamps source, so an ordinary lightning strike can directly damage the LED light source!

The above is the direct reason why early drive freeoutdoor LED lampsare easy to be damaged, so the key is to find targeted solutions to solve the problem of high damage rate of drive free solutions. Unfortunately, the technical level of earlier years cannot completely solve this problem; However, it is gratifying that with the progress and development of modern science and technology, the technical conditions for solving the above problems have been fully met.


First of all, the manufacturing technology of the rectifier bridge inside the LED light plate has been able to achieve the maximum withstand voltage of 1000 volts; Secondly, with the progress of lightning protector technology, the lightning protector can output a very low residual voltage after being struck by lightning, even as low as less than 40% of the maximum withstand voltage of the LED light source rectifier bridge, which completely solves the problem of easy damage of outdoor LED lamps fixtures!

Shenzhen greenway Electronics Co., Ltd. has specially developed and produced m998 series special lightning protectors suitable for outdoor drive free LED lighting schemes according to the needs of the drive free outdoor LED lamps schemes in the market. The maximum withstand voltage is divided into 10kV and 20kV products, and has obtained the safety certification of TUV in Europe, ETL in America and CQC in China in Asia.
