The small desk lamp can be placed on a flat stand. It includes a lamp base, a battery compartment, a switch, LED light beads, wires, and more. Its function is to concentrate the light in a small area, making it convenient for work and study. The colorful desk lamp is equipped with colorful slow-flickering LED light beads that change various colors.
Scientific Insights:
A desk lamp is an essential small household appliance in our lives. It focuses light onto a small area, making it convenient for learning and working. But do you know what components it consists of? How does it provide us with light? Let’s get started and assemble our own desk lamp.
1. Understand the basic structure of circuits
2. Can draw circuit diagrams easily
Experimental Cognition:
The function of electronic components and their notation symbols in circuits;
1 Battery-----Provides electrical energy—
2 Light bulbs-----Converting electrical energy into light
3 wires-----Connection and current conduction <The flow of water in a pipe is called water flow; the flow of electricity in wires is called current. This refers to the regular flow of electrical energy along conductive objects in a specific direction. It is invisible and intangible. The speed of the current is 300,000 kilometers per second.
4 Switch -- Controls the closing and opening of the circuit
5 Battery Case -- Holds batteries. It has + and - symbols on it, representing the positive and negative terminals respectively.
Scientific Expansion
In the early days, the lighting devices commonly used by people were candles, kerosene lamps, or gas lamps. These lamps burned kerosene and gas. As a result, they produced thick black smoke and strong unpleasant odors, and it was necessary to frequently add fuel and clean the lampshades, making them very inconvenient. More seriously, these lamps were prone to fires that could cause major disasters. Over the years, many scientists tried every means to invent a lamp that was both safe and convenient. On October 21, 1879, the American inventor Edison, after long and repeated experiments, finally lit the world’s first practical electric lamp. This lamp is a testament to humanity’s ability to conquer darkness. From then on, the name of this inventor, just like his electric lamp, entered thousands of households. He is the inventor hailed as the “King of Inventions,” Edison.
Safe voltage refers to a voltage that does not cause direct death or disability in people. Under normal environmental conditions, it is allowed for continuous contact and is known as ultra-low safe voltage; it is 36V
Definition of circuit diagram; connecting a power source, switch "Electric Construction", electrical devices, ammeters, voltmeters, etc. together to form a circuit, and representing them using standardized symbols—such a drawing is called a circuit diagram.
Experimental Report
Students can learn more about series and parallel circuits through books and the internet.
Make a desk lamp by yourself—you can draw or write on it. You can give it to friends or classmates. It may not be expensive, but it will definitely be thoughtful. A small desk lamp that warms your heart.
“Paper cup mini table lamp” has an attractive design, is easy to make, and offers success with minimal effort—ideal for younger children. It uses eco-friendly materials, turning discarded water cups into useful items. After simple assembly, these cups transform into various beautiful decorative nightlights, promoting waste recycling and achieving energy-saving and environmental protection goals.
Working principle: This is a typical switch circuit. The battery provides power, and the current flow is controlled by the switch. When connected, current passes through the switch, then through the LED light, where the current is converted into light energy, causing the small table lamp to light up.
