The beginning of the 21st century, the development of LED, which is a wonderful encounter between nature, humans, and science, will become an innovation in the world of light, a green technology revolution that is indispensable to humans. LED energy-saving lamps are the next generation of lighting sources after compact fluorescent lamps (i.e., ordinary energy-saving lamps), LED energy-saving lamps are environmentally friendly without mercury, recyclable, small power, high light efficiency, long life, turn on and off immediately, small light decay, rich color, adjustable light, and rich variety. Table lamps are a type of lamp, this electrical appliance is mainly placed on the writing desk or dining table for lighting. The light of the table lamp is relatively small and concentrated, so it will not affect the light of the entire room, the role is limited to the surrounding of the table lamp, convenient for reading, learning, working, and saving energy. Table lamps have become an invaluable artwork. Under the concept of light decoration, the decoration function of table lamps is more obvious. Next, let's make a energy-saving table lamp! You need to prepare a soldering iron and solder wire.

Experimental Purpose:
1. Understand the principles of circuitry
2. Applied solder

Principle Application:
A light-emitting diode (LED) is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of an LED is a semiconductor wafer. One end of the wafer is attached to a support, and one end is the negative pole. The other end is connected to the positive pole of the power supply, enclosing the entire wafer in an epoxy resin.

LED, which stands for light-emitting diode, is a solid-state semiconductor device that can directly convert electricity into light. LED energy-saving lamps use high-brightness white light-emitting diode light sources, which have high light efficiency, low power consumption, long life, easy control, no maintenance, and are safe and environmentally friendly. They are the next generation of solid-state cold light sources, with soft, vibrant, rich and colorful light colors, low loss, low energy consumption, green and environmental protection. They are suitable for long-term lighting in public places such as homes, malls, banks, hospitals, hotels, and other restaurants. They do not flash with direct current, which plays a good role in protecting the eyes, making them an ideal choice for desk lamps and flashlights.

The heart of a light-emitting diode (LED) is a semiconductor wafer. One end of the wafer is attached to a support, and one end is the negative pole. The other end is connected to the positive pole of the power supply, enclosing the entire wafer in an epoxy resin. The semiconductor wafer is composed of two parts: one is a P-type semiconductor, where holes dominate, and the other end is an N-type semiconductor, where electrons dominate. When these two types of semiconductors are connected, they form a P-N junction. When an electric current passes through the wire to act on this wafer, electrons are pushed into the P region, where they combine with holes, and then they emit energy in the form of photons, which is the principle of LED light emission. Because LEDs have low heat generation, they convert as much electrical energy as possible into light energy, while ordinary lamps convert a lot of electrical energy into heat due to their high heat generation, wasting it. In contrast, LED lighting is energy-saving.

LED energy-saving lamps, as a category of LED general lighting, derive their name from traditional lighting bulbs and energy-saving lamps. Their appearance is similar to that of traditional energy-saving lamps, which meets the traditional aesthetic preferences of consumers. The characteristics of LED energy-saving lamps include low cost, high light efficiency, large light emission area, no glare, and no double images. [1]

  Before assembling, please check if the circuit is unblocked and all the components are complete. Ensure that all contact points are in good contact. During the assembly process, be careful not to get glue on your clothes or skin. Keep the parts out of reach of younger siblings to prevent them from swallowing them by mistake! Do not play with them on your head, to avoid the model falling and injuring you!
