full resolution of LED support knowledge

There are different types of LED lamp beads different types, in fact, different LED caused by stent type according to different applications. Specific categories are: in-line stand, patch bracket, power bracket, flat bracket and cob holder. LED stent due to the need electrical and thermal conductivity, it will be used as the substrate metal. At the same time, some areas need to insulate, which requires use of engineering plastics. Therefore, the general LED support is through the metal stamping and then formed by injection molding. LED as a light emitting diode, the need for metal surface by plating silver as a good light reflecting material, it is generally LED for silver plating surface treatment.

Scaffolds using various power led street light with solar panel is not the same, low-power general use PPA, the power generally use PCT, there are some high-power uses EMC materials. All plastic materials are water-absorbent, so LED lamp production process of the bracket needs to be dehumidified baking.
Processing plating layer is the key point of the stent, the coating thickness and quality of the relationship between the flux, welding performance behind. A good selection of LED actually the first condition is to choose a good stand, the current market there are some pressing iron substrate, and then plating, injection form, which is relatively poor quality. The power is still better to use copper plating layer needs to be controlled in the 80U '' around better, but there are a lot of manufacturers only require plating to 40U '' can be, a thin coating stents to control the welding, can easily lead to false welding. Now stand there most powerful ceramic substrate, if it is to figure out the composition of ceramic materials ceramic coating these key points. Appearing on the market power of the COB lamp beads, copper plating is generally used after the injection formation, CITIZEN of COB lamp beads stent is used to form a laminated aluminum, aluminum CITIZEN course there is a certain selection criteria, the upper BT board material PCB material is employed, the intermediate adhesive is critical.
The following pictures are of various types of LED bracket:

  Integrated high-power stand
High-power integrated bracket, using copper aim is to strengthen the future of thermal conductivity, lower thermal resistance.

led street lighting Manufacturer are some in-line stand not explain the current lighting much.
Currently filament bulb shape and candle lights compare to live, then they stand and what look like? See the following figure:
  Filament support
The sapphire using metal strips wrap that's it! This is why the shape of the stent filament breakage easily one of the reasons.
Highlights bracket selection: a metallic material type. 2, plating quality (thickness, plating methods). 3, the plastic injection molding material.
