LED installation
Queendom LED light-emitting diodes have a great effect, and it is known that light-emitting diodes are widely used. In the field of car lights, lighting industry, wall washers, beauty instruments and other fields have played a great role. But what are the installation tips for such a small light-emitting diode.
1. Welding line: The official small chip usually has a driving current of more than 350ma, and the chip size is large. In order to ensure the uniformity and stability of the current injected into the chip, the positive and negative electrodes of the chip and the positive and negative electrodes of the bracket are welded with φ1.-φ1.25mil gold. Wire;
2. Phosphor: The driving current of the formal small chip is generally about 20ma, while the driving current of the inverted power chip is generally about 350ma. Therefore, the calorific value of the two is very different during use. LED installation tips
3. Solid crystal: The small chip is fixed by the insulating and thermally conductive adhesive at the inner point of the in-line bracket reflector cup, and the inverted chip is connected to the bracket base by silver glue or eutectic process with high thermal conductivity. The bracket base is usually the thermal conductivity. high copper;
4. Colloid: Small chips have low heat, and traditional epoxy resin can meet the packaging needs. Inverted power chips have high heat and need to be packaged with silica gel.
5. Glue molding: The chip is usually filled with epoxy resin glue in the particles, and then the bracket is inserted into the high temperature curing; the reverse power chip needs to be slowly filled with silica gel from the air intake hole of the lens. The operation should be improved during the filling process to avoid bubbles and cracks after baking, which will affect the yield.
6. Dispensing: The small chip package usually adopts the traditional method of filling the entire reflector cup to cover the chip.
7. Thermal design: Small chips usually have no additional thermal design. This is the end of today's light-emitting diode tips. If you have more questions or want to know, you can directly consult the online customer service.
