LED LAMP is a solid-state semiconductor device. The appearance of it may be oval, square, etc. It is composed of chip, package, metal wire, and bracket; the main light-emitting part is a chip in the package, and the package is made by epoxy, which is used to fix the bracket; a collective lens may be made at the top for more contracted beams. All LEDs are fixed, the long one is the positive electrode, the short one is the negative electrode, and the wavelength of the light is also the color of light, which is determined by the material that forms the p-n junction.
LED LAMP emits light by converting electrical energy into light energy, and the material of the light-emitting chip is a semiconductor with metal electrodes on the top and bottom, the positive electrode is a P-type semiconductor, and the negative electrode is an N-type semiconductor. When it is connected to a battery, electrons flow into the N-type semiconductor from the negative electrode of the battery, the electron hole flows into the P-type semiconductor from the positive electrode of the battery. When the electric current passes, the electron combines with the hole, then the energy emits in the form of light.

There are many advantages for LEDs, small component, long usage life, short response time, and high photoelectric conversion rate. Therefore, the application range is extremely wide, from traffic signal lights, indicator lights, automotive equipment, lighting, etc., LED products are everywhere in life.
LED Lamp is one of the essential component in electronic systems, the LEDs Oasistek produced are diversified, including 3mm, 5mm, round, concave, oval, square and super flux; which are the best choice for applying in all kinds of equipment with high brightness requirements, and we also provide custom-made services.
