The difference between led lamp beads and patches

The LED lamp bead is the same as the wick in the patch, but the angle of the lamp bead can be made very small, and its light is concentrated far away, but the irradiation range is limited.  led bulb components，The angle of the patch is generally larger, the light is scattered, and the shot is relatively close, but the irradiation range is relatively wide.


The power of the lamp bead is large, and the power of the patch is small. High-power LED lights generally use 1W high-power LED lamp beads, and low-power LED lights generally use SMD.


Cooling is different. The patch only needs to use the ordinary circuit board, and the natural heat dissipation can achieve a good heat dissipation effect, while the LED lamp bead needs to be equipped with an aluminum heat sink.

IPX1: stands for vertical dripping, dripping in the vertical direction has no effect, the water flow is 1mm/min, and the test is 10min. IPX2: 15 degrees of water dripping, when the vertical surfaces of the housing are inclined within 15 degrees, the vertical dripping water should have no harmful effect, the water flow is 3mm/min, and each inclined position is 2.5min. IPX3: Each vertical surface is exposed to rain within a range of 60 degrees, without harmful effects, the water flow is 10L/min, and the test time is 10min. IPX4: splashing water, splashing water in all directions of the casing has no effect, each vertical surface is exposed to rain within a range of 180 degrees, the water flow is 10L/min, and the test time is 10min. IPX5: water spray, no effect on the shell in all directions, the water
