LED patch lamp beads and LED straw hat lamp beads are widely used in the current market.
1. From the appearance, the straw hat type LED lamp beads are straw hat type round (hence the name), with long pins; Most SMDLED lamp beads are rectangular
Heterogeneous, no pins or only very short pins (artificial patch high-power lamp beads are also round, except for short pins).
2. From the perspective of power: the power of straw hat lamp beads is small, and the power above 0.5W is small (because it is not easy to dissipate heat). The power of the SMD lamp beads can be
Make it bigger. For example, a 5050 packaged SMD lamp bead can achieve 3W of power, while a straw hat shaped lamp bead cannot.
3. From the perspective of light emission: the visual angle boundary of straw hat shaped lamp beads is more obvious, and the SMD lamp beads are less obvious.
4. From the perspective of soft light; The light of straw hat shaped lamp beads is more dazzling, and the light of patch lamp beads is softer.
5. From the perspective of packaging lens: the lens of straw hat type lamp beads is hard and transparent epoxy resin, and the patch lamp beads are mostly soft and transparent silicone.
