The characteristics and application scenarios of various Lamp Cap

Lamp Cap refers to the interface of the lamp base or socket, used to connect the bulb or lamp tube, common Lamp Cap is screw Lamp Cap (such as E27, E14, E40, etc.), double foot lamp holder (such as G5, G13, etc.), round tube lamp holder (such as B15, B22, etc.) and so on.

Different Lamp Caps have different uses and scenarios. Common screw lamp holders are generally used for home lighting, such as indoor chandeliers, wall lamps, desk lamps, etc. Two-legged lamp holders are generally used for commercial lighting, such as ground spotlights, billboard light boxes, etc. Round tube lamp holders are mainly used for waterproof lamps in wet places such as kitchens and bathrooms. In addition, there are some special lamp holders, such as GU10, MR16, etc., which are often used for high-end lighting in exhibition halls, shopping malls and other occasions.

There are certain differences in the Lamp Caps of different countries. In Europe, commonly used screw lamp holders are E27, E14, E40, etc., while in the United States and Canada and other regions, commonly used A21, E26, E12 and other lamp holders. In addition, there are also differences in voltage and frequency in different countries, which will affect the electrical performance of the lamp. Therefore, the standardization and standardization of Lamp Caps is very important for the development of international trade and lighting industry.

With the process of global integration, many lamps now adopt international Lamp Cap standards, such as E27, E14, G5, G13, etc. These standard Lamp Caps can be applied to many countries and regions, and are convenient for lamp production, sales and maintenance. At the same time, there are some new lamp holders are gradually popularizing, such as intelligent wireless control lamp holders, which can remotely control the switch, brightness and color temperature of lights through mobile phone APP and other ways, in line with the needs of modern people for smart home and energy conservation and environmental protection.

Lamp Cap is a very important component of lighting products, different Lamp Cap types and standards are suitable for different scenarios and needs, so when purchasing and using lamps, it is necessary to choose the appropriate Lamp Cap according to the actual situation, and strictly abide by the relevant safety standards and regulations.

At the same time, the Lamp Cap is also an important part of the development of the lighting industry. With the continuous development of LED lighting technology, more and more new Lamp Caps are being introduced. For example, LED COB lamp holder, SMD lamp holder, etc., these new lamp holders can achieve higher power density and smaller lamp size, so that the performance and reliability of LED lamps are more optimized.

Lighting standards and technical development levels in different countries and regions will also have different impacts on the Lamp Cap industry. For example, the EU has strict energy efficiency standards for lamps, requiring parameters such as power factor and light efficiency of lamps to meet certain standards. This requires that the design and manufacture of lamp holders need to meet these standards, so as to promote the technological upgrading and innovation of the Lamp Cap industry.

Although the Lamp Cap is only a small component, it is an indispensable part of the lighting industry and consumers, and it is also an important foundation for achieving green energy-saving lighting.
