led lamp bead and patch difference

Let's take a look at the characteristics of led beads first. The Angle of LED lamp bead is very small, which belongs to the relatively concentrated light, the range is very far, but the irradiation range is limited; The general Angle of the LED patch is very large, which belongs to the light is relatively scattered, the irradiation range is wide, but the range is relatively close. LED beads are used to discharge light, and LED patches are used in cold luminescence.

What are the advantages of patches in comparison? led patch is also a kind of led lamp beads ah. Common leds have two or four pins, while others have no pins and are welded close to the copper foil on the circuit board. You want to choose the key lamp beads is to consider the color temperature, color index, light effect, light failure, in addition to the quality of power supply, etc., buy these things to buy better quality.

What's the difference? LED beads chip has a lot of forms, mainly considering a variety of power heat dissipation form to formulate. You LOOK FOR THE SALESMAN OF THE FACTORY THAT MAKES LED CHIP ON THE NET, ASK THEM TO WANT A DATA, ASK THEM AGAIN NEXT, CAN UNDERSTAND VERY FULLY.
