How to determine how many watts of LED lamp beads are? The difference between LED lamp beads and SMD part two

The difference between LED lamp beads and LED patch

The core of the LED lamp bead and the LED patch are the same, the angle of the lamp bead can be made very small, (the light is more concentrated, the shot is far, but the irradiation range is limited) The general angle of the patch is relatively large . Supplement: The power of the lamp bead is large, and the power of the patch is small.

1. The power of LED lamp beads is different. High-power 8x8 LED lamps generally use 1W high-power LED lamp beads, 1-3W coexisting high-power LED lamp beads, and COB high-power. The maximum power of a single LED of high-power lamp beads can be more than 200W. Low-power LED lamps generally use SMD lamp beads, mainly including these types: 5050 lamp beads, 0.2W each, 3528 lamp beads, 0.06W each, 3014 lamp beads, 0.1W each, 5630 lamp beads, Each 0.5W, 5730 lamp beads, each 0.5W.

2. The cost is different. From the perspective of product cost, the cost of high-power LED lamp beads is higher than that of low-power. The power can meet the requirements as long as the ordinary circuit board is used and natural heat dissipation is added.

3. The applied LED lamps are different. High-power LEDs are basically used in products that require high light sources per unit area, such as LED ceiling lights, LED flood lights, LED bulbs, street lights, and so on. Low-power LEDs are basically used in products with less patchable area, poor heat dissipation, and low requirements for the light source in a unit area, such as LED ceiling lights, LED fluorescent lights, LED panel lights, and LED strips Wait.

How to judge how many watts of led lamp beads are?

Low power (such as 5mm straw hat, 5mm concentrator, 3528 package, etc.), about 0.06W.

Medium power (such as 8mm straw hat, 10mm straw hat, 5050 package, etc.) 0.2W-0.5W.

High-power ones are 1W, 3W, 5W, 10w...100w
