Semiconductor devices, which can be directly converted into light. LED heart is a semiconductor

The end of the chip is attached to one bracket at one end, and one end of the wafer is negative, and the other end is connected with the cathode of the power supply, so the whole chip is encapsulated by epoxy resin.. The semiconductor chip is made up of two parts, a part of which is the P type semiconductor, and the hole occupies the dominant position in it, and the other end is the N type semiconductor, which is mainly electronic. But when these two kinds of semiconductor connect, they form a P-N knot ". When the current through the wire is applied to the wafer, electrons will be pushed the p region, in the p zone electron hole with compound, and then in the form of photon emit energy, this is LED light-emitting principle. And the wavelength of light is the color of the light, which is determined by the material that forms the P-N knot..
