Abstract

The invention discloses a six-pin 5050 LED lamp welding pad, which comprises a first to a sixth pin welding pad, and a first to a sixth copper sheet in corresponding connection with the first to the sixth welding pad, wherein the first pin welding pad and the second pin welding pad are in a group; the third pin welding pad and the fourth pin welding pad are in a group; the fifth pin welding pad and the sixth pin welding pad are in a group; the three welding pad groups are arranged in sequence; centers of the first pin welding pad, the third pin welding pad and the fifth pin welding pad are located in the same straight line; centers of second pin welding pad, the fourth pin welding pad and the sixth pin welding pad are located in the same straight line; the two straight lines are mutually parallel; and the first to the sixth copper sheet has the same area. The six copper sheets connected with the six pin welding pads have the same areas to enable cooling effects of the six pin welding pads to be the same, thereby avoiding cask effects and improving the cooling efficiency.

Description

technical field [0001] The invention belongs to the field of LED applications, and in particular relates to a welding pad of a six-pin 5050 LED lamp. Background technique [0002] The reason for the junction temperature of the LED is that not all of the added electrical energy is converted into light energy, but part of it is converted into heat energy. The light efficiency of LED is currently only 100lm / W, and its electro-optical conversion efficiency is only about 20~30%. That is to say, about 70% of the electrical energy is turned into heat energy. The generation of LED junction temperature is caused by two factors: 1. The photons generated inside cannot be completely emitted to the outside of the chip and finally converted into heat. This part is the main one, because the current so-called external quantum efficiency is only 30%. Most of it is converted into heat. 2. The internal quantum efficiency is not high, that is, when electrons and holes recombine, photons cann...
