How about straw hat LED Lamp Beads and patch lamp beads?
1. From the appearance: straw hat shaped LED lamp beads are straw hat shaped round (hence the name), with long pins; Most SMD LED Lamp Beads are rectangular, with no pins or only very short pins (a kind of manual SMD high-power lamp beads are also round, except those with short leads);
2. From the light emitting point of view: the angle boundary of straw hat lamp bead is obvious, and the patch lamp bead is not obvious;
3. From the perspective of soft light: the light of straw hat lamp beads is more dazzling, and the light of patch lamp beads is softer;
4. From the perspective of packaging lens: the lens of straw hat lamp bead is hard and transparent epoxy resin, and the patch lamp bead is mostly soft and transparent silica gel;
6. From the perspective of power: the power of straw hat lamp beads is small, and the power of more than 0.5W is less (because it is not easy to spread heat). The lamp bead power of the patch can be larger. For example, the 5050 packaged chip lamp beads can achieve a 3W power, but the straw hat shaped lamp beads cannot.
