There are more than fifty kinds of LED lamp's raw materials, those materials which may also contain sulfur, chlorine, and bromine. In a sealed, high-temperature environment, such as sulfur, chlorine and bromine may be volatilized into the gas and etching LED light source. Therefore Lighting Factory has the responsibility and obligation to provide a sulfur-free environment to the LED light source.

LED lamps may contain sulfur/chlorine/bromine materials:

1 Power: LED built-in power there are thirty kinds of raw materials, in which the PCB board, sulfur rubber cord, and rubber insulating plastic packaging containing halogen flame retardant plastics, electronic components, may contain sulfur, chlorine, and bromine. When the heating power, the material can be volatilized sulfur \ chloro \ bromine gas and sulfur \ chloro \ bromine vapor in combination with nitrogen-containing gas, corrosive harmful gas is generated, causing corrosion of the LED.

2. PCB board: the production of circuit boards available in the market there is a certain element of residual sulfur content, although PCB circuit board manufacturers in process technology will clean sheet, eliminate residual sulfur-containing chemical solvents, the general production process is more difficult to completely clean.

3 sulfur rubber cord and rubber insulating plastic packaging: vulcanized rubber can be kept at a temperature range of -65 ~ 250 ℃ resilient and has excellent electrical properties and chemical stability, waterproof, resistant to ozone, weather aging, combined with the use of simple technology applicability, it is widely used in the electronics industry, as a coating, potting, packaging materials electronic components.

4 halogen-containing flame retardant material: printed circuit boards, shell, plastic, aluminum plate insulation layer: PBB, PBDE, TBBP-A, PCB, six bromododecane, Tribromophenol, halogen compounds, such as short-chain chlorinated kinds of paraffin often used as a flame retardant, used in printed circuit boards, shell, plastic, and other materials. When these materials are heated to a certain temperature, the halogen-containing gas will evaporate, when a halogen-containing gas is in combination with nitrogen-containing water vapor, corrosive harmful gas is generated, causing corrosion of the LED. Also according to many scientific studies show that the halogen-based flame retardants have become diffused everywhere everyday environmental pollutants in the combustion heating process will release harmful substances, threatening the health of the human body, the environment, and the next generation of children. Contrary to the halogen-based flame retardant used in the LED environmental performance. So Jin Jian detect recommends LED material suppliers try to use non-halogen flame retardant materials. best led headlights http://bestledheadlight.com/

5 Paste flux: flux component in the activator is usually an organic acid containing a halogen or a small number of components, it can quickly eliminate the effect of the oxide film is welded to the metal surface, lowering the surface tension of the solder, the solder is quickly spread on weld metal surface. The halogen is usually bromine/chlorine can become black silver bromide, silver/silver chloride. led grow lights https://www.eneltec-led.com/products/led-grow-lights

6 Ink: Green oil PCB board, white aluminum panel, character, paint lamps, and radiator are likely to sulfur. This is because the oil paint has a sulfide, the composition is very complex, elemental sulfur, hydrogen sulfide, thiols, thioethers, disulfides, and the like. Wherein the active sulfur compounds such as hydrogen sulfide, mercaptans, and elemental sulfur, etc. can be directly chemically reacted with the silver. Water contained in crude oil paint will contain sodium chloride, magnesium chloride, and calcium chloride, and other salts. In crude oil processing, magnesium chloride and calcium chloride is easily heated hydrolyzed to produce hydrogen chloride that has a strong corrosive. So Jin Jian detect recommend LED material supplier selection sulfur-free or low-sulfur crude oil as paint material.
