There are currently two types of low pressure sodium lamps on the market, one is a conventional low pressure sodium lamp and the other is an economical low pressure sodium lamp. In general, the difference between the two types of lamps is that the economy lamps are more efficient and consume less power. But this is not to say that the luminous flux of the economical low-pressure sodium lamp is high. That is to say, in a luminaire device requiring a certain level of illumination, it is not possible to simply replace the conventional low-pressure sodium lamp with a more economical and economical low-pressure sodium lamp. Economical lamps have better thermal insulation properties than conventional lamps. To produce the same light output, an economy lamp requires only a lower input of electrical power, but the overall light flux of the lamp is reduced. Economical low-pressure sodium lamps work well on the working circuits of conventional low-pressure sodium lamps. However, when they work on choke-type ballasts or self-disaster magnetic transformer circuits, the advantages of low energy consumption are not very good. Obvious.

The low-pressure sodium lamp is an electric light source that emits light by using low-pressure sodium vapor discharge, and is coated with an infrared reflecting film in its glass casing, which is an electric light source with less light decay and highest luminous efficiency. The low-pressure sodium lamp emits a monochromatic yellow light for use in places where light color is not required, but its "transparency" performance is excellent, especially suitable for highways, traffic roads, municipal roads, parks, courtyard lighting, It enables people to clearly see objects with small chromatic aberrations. Low-pressure sodium lamps are also a high-efficiency lamp that can save electricity by replacing high-pressure mercury lamps, and the application sites are also expanding.
