Lighting type

1, incandescent lamp 1909 American scientist Coolidge invented tungsten filament as filament, which improved the brightness and life of incandescent lamp. The filament in the glass bulb is electrified and heated, so that the filament generates thermal radiation and emits light. Lamp holder is the electrical and mechanical connection part of incandescent lamp, which is mainly divided into screw lamp holder, focusing lamp holder and special lamp holder according to form and use. Commonly used in basic lighting and decorative lighting of residential buildings, it has the advantages of convenient installation, immediate start-up and low cost.

2. It has a wide working voltage range, from a few volts provided by the battery to the mains voltage, with low price and no need for additional circuits. Its main applications are home lighting and places where intensive low-voltage lamps are needed, such as flashlights and console lighting. Only 10% of the input energy is converted into visible light energy, and the typical life span ranges from tens to thousands.

3. The invention of tungsten halogen lamp 1959 brought the technology of incandescent lamp to a new height and prolonged its life. Compared with halogen-free incandescent lamps with the same rated power, tungsten halogen lamps are much smaller in size and allow to be filled with heavier high-pressure gas (more expensive). These changes can prolong its life or improve its light efficiency.

4. Tungsten halogen lamps can also be directly connected to the power supply without the control circuit. The life of ordinary incandescent lamp is 1000, and the life of tungsten halogen lamp is half of it, and the luminous efficiency is improved by 30%. Tungsten halogen lamps are widely used in motor vehicle lighting, projection systems, special spotlights, low-cost floodlighting, stage and studio lighting and other occasions that need to surpass halogen-free incandescent lamps in compactness, convenience and good performance.
