SM2450S

SM2450S application field and working principle

SM2450S is a type of ceramic metal halide lamp. With its excellent color temperature, color rendering index, luminous efficiency, long service life and instant start, it is widely used in public places, such as supermarkets, factories, schools, theaters, stadiums, airports, and other places requiring lighting.

The working principle of SM2450S is as follows: When mains voltage is applied to the electrodes on both ends of the lamp, a surge of current passes through the arc tube and excites the electrode. At this time, the light-emitting particles in the arc tube will emit light source. The dextrose powder contained in the arc tube is very fine white powder mixed with metal compounds, which can strongly absorb ultraviolet light and release visible light, so that the ultraviolet light is transformed into visible light. Thus, the arc tube becomes a light-emitting source. When the white powder is excited to a level of energy exceeding its ionization energy, electrons are released and become free electrons in a plasma state, and the electrons and gas atoms collide with each other to consume their energy and emit visible light. The combination of these processes can generate light.

The SM2450S is the perfect choice for public lighting applications because of its excellent performance. Its color temperature can reach more than 6500K, while its color rendering index can reach more than 80. In addition, its luminous efficiency is up to 140 lm/W, which is very energy-saving and environmentally friendly. Moreover, SM2450S has a super long service life, up to 30000-50000 hours. Moreover, it also has the characteristic of fast start, instantly lighting as soon as power is applied. So, it can be used in places where frequent start-stop is required.

In summary, SM2450S ceramic metal halide lamp is a good choice for public lighting applications. It has excellent color temperature, color rendering index, luminous efficiency, long service life, and instant start. Therefore, it is widely used in commercial, industrial, and public places such as supermarkets, factories, airports, theaters, and stadiums.
