The latest version of high pressure sodium lamp 50-3000 w for road floodlight, high pressure sodium lamp
metal halide light spectrum is mainly for white light output, suitable for germination, stem leaf growth stage.
High pressure sodium lamp spectrum mainly yellow light output, apply to blossom and bear fruit stage can also be used for all plant growth stage
High pressure sodium lamp when using a white gold, have high luminous efficiency, less consumption, long life, light color is good, strong ability to penetrate the fog and trap, the advantages of color temperature 2100 k. Widely used in road, highway, airport, port, dock, station, plaza, street interchange, industrial and mining enterprises, park, garden lighting, and plant cultivation. High color rendering of high pressure sodium lamp is mainly used in the gymnasium, exhibition hall, amusement parks, department stores and hotels and other places lighting.
Start the feature
High pressure sodium lamp starts, in the initial stage is mercury vapor and low-pressure discharge of xenon. At that time, the light bulb working voltage is very low, the current large; To continue with the discharge process, the arc temperature rise, mercury, sodium vapour pressure is decided by the discharge tube cold end temperature, when the discharge tube cold end temperature to achieve stability, discharge will be stable, bulb of luminous flux, work voltage, current and power are in normal working condition. Under normal working conditions, the whole process takes about 10 minutes.
Working circuit system
Working in high pressure sodium lamp circuits in addition to the light bulb, also must be trigger high-pressure sodium lamp inside or outside the trigger high-pressure sodium lamp respectively the corresponding work of circuit, such as light bulbs + electronic ballasts can meet the needs of high pressure sodium lamp to work properly.
