Since the 21st century, LED technology, developed through remarkable interactions between nature, humans, and science, has become an innovative element of the light world and a vital green technology revolution for humanity. LED energy-saving lights represent a new generation of lighting sources following compact fluorescent lights (i.e., conventional energy-saving lights). These lights are environmentally friendly, contain no mercury, can be recycled, have low power consumption, high luminous efficiency, long lifespan, turn on immediately upon activation, resist frequent switching, show minimal light decay, offer rich colors, and allow dimming. A desk lamp is a type of light source primarily placed on desks or dining tables for illumination. The light emitted by a desk lamp is relatively limited in range and focused, thus not affecting the overall room lighting; its effect is confined to the area around the lamp, making it convenient for reading, learning, and working while saving energy. Desk lamps have become rare artworks. Under the concept of emphasizing minimal decoration and emphasizing decorative elements, the decorative function of desk lamps becomes even more evident. Let’s get started and create an energy-saving desk lamp! You will need an electric soldering iron and solder wire.

Experimental Objectives:
1. Understand the principles of circuits
2. Applying solder

Principle Application:
Light-emitting diodes are solid-state semiconductor devices that convert electrical energy into visible light; they can directly transform electricity into light. The core component of an LED is a semiconductor chip. One end of the chip is attached to a support, with the negative terminal at one end and the positive terminal connected to the power source at the other end. The entire chip is then encapsulated in epoxy resin.

LED is a solid-state semiconductor light-emitting diode, a solid-state semiconductor device that can directly convert electricity into light. LED energy-saving lights use high-brightness white LED light sources. They offer high luminous efficiency, low power consumption, long lifespan, easy control, no maintenance required, and are safe and environmentally friendly. They are a new generation of solid-state cold light sources with soft, vibrant, and diverse colors, low loss, low energy consumption, and green environmental benefits. They are suitable for long-term lighting in homes, shopping malls, banks, hospitals, hotels, restaurants, and other public places. With DC power without flickering, they provide excellent protection for the eyes and are the best choice for table lamps and flashlights.

The heart of an LED is a semiconductor chip. One end of the chip is attached to a holder; one end is the negative terminal, and the other end connects to the positive terminal of the power source, with the entire chip encapsulated in epoxy resin. The semiconductor chip consists of two parts: one is P-type semiconductor, where holes predominate, and the other is N-type semiconductor, where electrons dominate. When these two types of semiconductors are connected, a P-N junction is formed between them. When current passes through the chip via a wire, electrons are pushed into the P region, where they recombine with holes, and then energy is emitted in the form of photons—this is the principle behind LED lighting. Since LEDs generate little heat, they convert electrical energy into light energy as much as possible, whereas ordinary lights generate significant heat, converting much of the electrical energy into thermal energy and wasting it. In comparison, LED lighting is more energy-efficient.

As a category within the LED general lighting sector, LED energy-saving lights derive their name from traditional bulb lights and energy-saving lamps. The appearance of LED energy-saving lights is similar to that of traditional energy-saving lights, which meets consumers' traditional aesthetic preferences. Characteristics of LED energy-saving lights include: low cost, high light efficiency, large light output, no glare, and no double images.[1]

Please check that the circuit is unobstructed and all components are intact before assembly, as well as ensure all contact points are properly aligned. During assembly, be careful not to let glue get on your clothes or skin. Keep the components out of reach for younger siblings to prevent them from accidentally swallowing them! Do not play with them on your head, as the model may fall and hurt you!
