The difference between LED high bay lights and halogen, high bay lights, etc.

　　How energy-saving are LED high bay lights? Let's learn about the comparison between LED high bay lights and high pressure sodium lights.

　　1. Main features of LED high bay light:

　　1) The light source adopts a single high-power LED integrated light source, a unique multi-chip integrated single-module light source design, and imported high-brightness semiconducr chips. It has the characteristics of high thermal conductivity, low light decay, pure light color, no ghosting, etc.;

　　2) The unique integrated design of heat dissipation and lamp housing, perfectly combined with the electrical box, effectively conducts and diffuses the heat, thereby reducing the temperature in the lamp body, and ensuring the life of the LED light source for 50,000 hours. According  the calculation of lighting for 11-12 hours a day, the LED high bay light does not need  be replaced in 12 years.

　　3) The surface of the radiar is treated with anodized anti-corrosion, with compact and beautiful structure, good anti-corrosion, waterproof and dustproof performance;

　　4) The energy-saving effect is obvious. The high-power LED light source is equipped with imported high-efficiency power supply, which can save more than 70% of energy compared with sodium lamps;

　　5) Green and environmentally friendly, no pollution, no lead, mercury and other polluting elements, no pollution  the environment; 7. Good color rendering, more true  the actual color. Various light colors are available, which can meet the needs of different environments, eliminate the depressed mood caused by the high or low color temperature of traditional lamps, make the vision more comfortable, and improve the work efficiency of workers;

　　6) Adopt constant current and constant voltage control, suitable for wide voltage (AC85V-265V)  overcome the power grid, noise pollution and light instability caused by the ballast, and avoid the stimulation and fatigue caused  the eyes during work;

　　7) Excellent decorative effect, special surface treatment technology, various colors for appearance, simple installation, convenient disassembly, and wide application range.

　　The LED high bay light uses ultra-bright LED white light as the light source, the outer shell is made of aluminum alloy (cusmer optional), the outer cover is made of high-efficiency lens (cusmer optional), and the heat dissipation adopts copper sheet heat conduction and aluminum alloy strip for heat dissipation. Natural air circulation makes The heat dissipation is more perfect, combined with the different needs of cusmers, the shape will continue  change. The power of LED high bay lights is only 20% of sodium lamps, which is equivalent  100W LED high bay lights can replace 500W sodium lights, especially in line with the country’s "green and low carbon" .

　　2. Main features of high pressure sodium lamp:

　　The high-pressure sodium lamp emits golden white light when in use, and has the advantages of high luminous efficiency, low power consumption, long life, strong fog penetration and no insect attraction. When the power supply voltage of the high-pressure sodium lamp increases, the lamp power will increase significantly. For example, when the voltage is 110% of the rated value, the lamp power will reach about 128% of the rated value.

　　For road lighting, after midnight, the voltage rises a lot, and the lamp power and output luminous flux are greatly increased. At this time, it is when o high illuminance is needed. Therefore, when SELB or LB is used  increase the power supply voltage, it is still Maintaining the lamp power basically unchanged is of great significance  energy saving, and it also has a significant effect on prolonging the service life of the lamp and ballast.

　　3. Comparison of energy saving between LED high bay lamps and high pressure sodium lamps:

　　1) Power density selection: The power density of traditional lamps is 10-25 watts/m2, the power density of LED lamps can be designed at 3-15 watts/m2, and the general office space LED lamps are 3-10 watts/m2. For occasions requiring high brightness, such as hotels and shopping malls, it can be designed at 10-15 watts/square meter.

　　2) Power selection: The power of LED high bay lamp is considered according  the traditional high pressure sodium lamp power 1/5.

　　3) Power facr: The power facr of LED lamps is above 0.95, while the power facr of traditional high-pressure sodium lamps is around 0.6. , Power efficiency: The power efficiency of LED lamps is above 0.9, while the power efficiency of traditional high-pressure sodium lamps is about 0.6. 5. Life span: LED light source has a life span of 30,000-50,000 hours, while the life span of a traditional high-pressure sodium lamp is 3,000-8,000 hours. 6. The use of LED lighting can reduce the capacity of lighting cables and transformers. Compared with traditional lighting, it can reduce the investment of transformers and cables by at least half.

　　4. Comparison between LED high bay lights and traditional halogen high bay lights

　　Chip selection:

　　At present, the more well-known brands of high-power LED light sources on the market are:

　　CREE, OSRAM, NICHIA, Lumileds (the earliest LED), and Epistar and Addison from Taiwanese manufacturers are also popular brands. In order  ensure product stability, cost performance and practicability, we use the well-known OSRAM chip as the light source for this industrial and mining lamp.

　　Power selection:

　　The characteristics of traditional high bay lights are compared with 400W halogen lamps and new LED high bay lights. There are obvious differences, as shown in the following table:

　　Taking in account the problem of halogen lamp decay and secondary light emission in actual use, the actual luminous efficiency is lower than 30lm/W, which often fails  reach the nominal 70%. Based on this, the power of the LED high bay light we developed for the first time is set  about 150W. Once the lighting effect meets expectations, it will save more than 60% of energy than traditional lamps.

　　Cost and benefit assessment:

　　As we all know, compared with high-pressure sodium lamps or metal halide lamps for plant lighting, the initial investment cost of LED high bay lamps is obviously much higher than that of traditional lamps. However, because the LED light source has the characteristics of high luminous efficiency, and when it is made in a lamp, the advantage of the LED light source's strong directivity is easily reflected. The efficiency of the LED lamp is much higher than that of the traditional lamp, so its energy-saving characteristics can be Obviously manifested.

　　The LED high bay light uses the 4th generation light source. Compared with other light sources, such as incandescent lamps, high pressure sodium lamps, high pressure mercury lamps, and induction lamps, it has the following advantages:

　　Voltage:

　　The LED industrial and mining light source uses a low-voltage power supply, with a single voltage between 1.9-4V, which is a safer power supply than using a high-voltage power supply.

　　efficacy:

　　High luminous efficiency, the highest luminous efficiency in the laborary has reached 161 lm/w (cree), which is currently the highest luminous efficiency lighting product. In theory, the luminous efficiency per watt of the LED is as high as 370 LM/W. In the current chip structure without any changes, the good technology allows the LED  reach 150 LM per watt without any problems. When this brightness is reached, all lighting fields Basically they can be replaced. It is estimated that the LED light source will reach a light efficiency of 300 lumens per watt in the next 1-3 years. At present, the LED in the US laborary has reached a luminous efficiency of 161 lumens per watt, with a tal luminous flux of 175 LM.
