FAQ:What's your products warranty ?

- Q: Is high pressure sodium lamp the same as metal halide lamp?
- Metal halide lamp is developed on the basis of high pressure mercury lamp. It overcomes the disadvantage of poor color rendering of high-pressure mercury lamp. Some metal halides are added to the high pressure mercury lamp, and the metal arc is continuously supplied to the arc through the cyclic action of the metal halide, and the metal atoms are excited by the arc in the arc to radiate light. It has many advantages, such as good light color, high light efficiency and little influence by voltage, so it is an ideal light source at present. The metal halide lamp with various colors can be made by selecting the appropriate metal halide and controlling the relative proportion.
- Q: Question 1: what is the capacitance of the high pressure sodium lamp? Question two: it's only connected to the light zero line of each lamp. What's the difference between the capacitor and the electric box? Question three: what can happen if there is no capacitive lamp that can be lit?
- This capacitor is used in reactive power compensation, which can reduce the reactive current of high pressure sodium lamp;
- Q: High pressure sodium lamp is a kind of high brightness street lamp. What kind of material is its tube material?
- The glass shell by vacuum, the vacuum degree is only 6.6X10 -2 Pa, can make the oxidation of metal parts, lighting effect and stable work; so the amount of getter placed in a glass bulb, bulb can be increased to 1.4X10 the degree of vacuum in a high vacuum state -4 Pa. At present, high pressure sodium lamp generally uses barium getter, it is the barium titanium alloy in the metal ring, and then fixed on the getter evapotranspiration does not affect the position of the output light. After the lamp is evacuated, the metal ring is heated by high-frequency induction, so that the inner ring of the barium titanium alloy is heated to evapotranspiration, and the residual harmful gas is absorbed during the evaporation process, and a black mirror surface is formed at the neck of the glass bulb. It must be pointed out that the getter placement is very important, the black mirror does not hinder the light output is appropriate; in the use of the process found in the black mirror of all or part of a gray white, indicating the bulb has leak, can not continue to use, must be changed to a new bulb.
- Q: What are the advantages of HPS lamps and what are they used for?
- Color rendering: 70-80, if using three primary color phosphor is higher; high pressure sodium lamp is 25, low pressure sodium lamp is lower, is faint yellow, even if the total brightness is higher than LED, but the visual effect is worse than LED.
- Q: Using high-pressure sodium lamp as a plant growth lamp to promote the growth of plants. How large is the light of a 600W lamp, so that it can achieve the best simulated sunlight effect?
- The light environment is one of the most important physical environmental factors necessary for plant growth and development, through the quality control regulation, plant morphogenesis is an important technology field cultivation facilities. The light spectrum of a direct impact on plant photosynthesis is mainly red and blue light, red light is mainly concentrated in 630~660nm, its role is to help the flowering plants, blue mainly concentrated in 450~470nm, its role is to help plant long stem leaves.
- Q: What is the color temperature of high pressure sodium lamp?
- Can be understood as 1950K-2200K, but in fact the color temperature concept is for the white light system, the sodium lamp is colored light, low color rendering, "color temperature" for sodium lamp is not practical.
- Q: How much compensation capacitor is required for the 250W high pressure sodium lamp?
- Because of the high voltage sodium lamp ballast inductance element, the power factor is very low, generally about 0.5 COS. The general vicinity, energy consumption is about 20% ballast tube near the rated current of high voltage sodium lamp 150 Watt: I = P/U/COS (phi = 15030) /220/0.5 = 1.6 (A) if the capacitance of the power factor increased to 0.95 required: C = (3183 * I * sin) /U: sin = Reagan (0.95 - Phi COS Phi Square) C = (3183 x 1.6 x sqrt (0.95 - 0.5 * 0.5) /220 = 19 (F).
- Q: The number of Duodawa LED street is equivalent to the number of Duodawa high pressure sodium lamp?
- The reason for power saving is the efficiency of the drive circuit and the power factorThe driving force of high pressure sodium lamp is inductive and electronic. The efficiency of inductance is less than 60%, and the efficiency of electronic is less than 80%. It is a thermal light source, which can radiate heat
- Q: Which is better, high pressure sodium lamp and LED lamp?
- Non comparability. The power of high pressure sodium lamp is great and the cost is low. LED lamp has high luminous efficiency, but the power is not big, and the cost is high. Mainly on what occasions.
- Q: What is the basis for deciding that, for example, 21W LED street lights can replace 50W HPS?
- Through the analysis and comparison of the final luminous efficiency value, we can find that the luminous efficiency of 100W LED street lamp is almost 2 times higher than that of 250W high-pressure sodium light. That's why 100W LED street lights can be used instead of 250W high pressure sodium lamps.
