What are the light sources of outdoor LED floodlights?
2022-02-21
There are roughly four types of light sources for outdoor LED floodlights.
1. A welding type LED high-power light source, each 1 watt, is manually welded with a soldering iron, the light source generates a large amount of heat, and the shell of the floodlight needs to be thick to ensure the quality of the outdoor floodlight; the high-power light source welding process Electrostatic treatment should be done well , Workers should wear an electrostatic wristband to connect to the ground, otherwise the lamp will die easily. The quality stability cannot be ensured during the use of outdoor lamps. The light source often has leakage or false welding.
2. The second type is the integrated type. The packaging machine integrates the chip on an aluminum substrate or a copper substrate. There are two types of integrated light source and cob light source. The power has different levels, ranging from 3W to 50W, and the brightness is also high. There are imported and domestic products. However, due to the integrated heat dissipation, the heat dissipation requirements of the casing are relatively high. If the heat dissipation of the casing is not good, it is easy to cause dead lights.
3. The three types are SMD type, Osram light source, Cree light source and Philips light source. These light sources are imported, ranging from 1W to 3W. In the production process of outdoor floodlights, the light sources are all welded by automatic machines, with low calorific value and high brightness. High quality and stable quality, it is the preferred light source for outdoor engineering lamps.

4.There is also a type of DOB light source, which is an integrated, drive-free solution. All components and wicks are installed on the same aluminum substrate and directly connected to high-voltage AC220V. The heat generation is very large. This kind of safety factor is not high, and the quality and safety are very Hard to guarantee.
