Q:How to distinguish between metal halide lamp and high pressure sodium lamp bulb
Comfort and a white light dark yellow light high-pressure sodium lamp and high-pressure mercury lamp emits blue light emitted by a halogen lamp, the comfort of pure white light favored by the majority of industrial sites and commercial establishments, it can make the darkroom or night scenery as the sun shining like bright colors.
Q:Which is better, a metal halide lamp or a high pressure sodium lamp?
Metal halide lamps are mainly used for indoor lighting, such as ceramic, metal halide lamps are mainly used in shops, etc., where lighting requirements are higher, the common metal halide lamps are generally used in warehouses, factories, and other regional lighting.
Q:What's the color difference between metal halide lamp and high pressure sodium lamp?
Comfort and a white light dark yellow light high-pressure sodium lamp and high-pressure mercury lamp emits blue light emitted by a halogen lamp, the comfort of pure white light favored by the majority of industrial sites and commercial establishments, it can make the darkroom or night scenery as the sun shining like bright colors.
Q:How can the ballast inductance of high voltage sodium lamp reach the high voltage of several thousand volts?
Thereafter, the starter IGN disconnects the B and N terminals and makes the B and LP terminals short circuited. Since the high voltage sodium lamp has not been lighted, it is in the state of shutdown, has no current flow, and because the current on the inductor can not be mutated, the inductance will produce at least a high voltage of over 1000 volts.
Q:Factory lighting why use high-pressure sodium lamp, what are the advantages?
You should be wrong, the factory lighting is generally metal halide lamp, OK?.Sodium light is generally used for street lighting and agricultural lighting.
Q:Relationship between wattage and height of street lamps (high pressure sodium lamps)
There is no rigid height requirement, but the installation height of 250W is best over 8 meters, and the installation height of 400W is better than 10 meters, which is purely personal experience.The utilization coefficient of high pressure sodium lamp is generally between 0.3~0.5. Usually take 0.4
Q:Specific algorithm of high voltage sodium lamp power
Power factor I do not remember, the current is 1.8A, which is in the case of voltage 220V current, 380V current is 1.05263, specifically according to your location in different time periods of different voltage to calculate the actual working current I=W/U
Q:How much compensation capacitor is required for the 250W high pressure sodium lamp?
The transformer efficiency is calculated as 0.8, 315KVA can load capacity of about 252KW, power factor is increased from 0.7 to 0.95 per KW capacity 0.691 kilovar, required capacity: 252 x 0.691 = 174 (kilovar) total current capacitance: I = C/1.732 * U = 174/ (1.732 x 0.45) = 223 (A).
Q:Technical parameters of high pressure sodium lamp
lumen maintenanceThe luminous efficiency is up to 80 lumens / watt, and the highest luminous efficiency is 140 lumens / watt
Q:Can metal halide lamps and high pressure sodium lamps be used indoors? Do I need a single rectifier?
Metal halide lamp (Metal Halide Lamp) is the AC power supply, arc discharge luminous lamp in halide mixed vapor mercury and rare metal, metal halide lamp is made to add a variety of metal halide light source in the third generation based on high pressure mercury lamp. Sodium scandium metal halide lamp by lighting the lamp, has the characteristics of high luminous efficiency, good color, long life performance significantly, is a new energy-saving light source close to daylight, widely used in the stadium, exhibition center, large shopping malls, industrial buildings, street square, station, wharf and other places of indoor lighting.
