The difference between LED high bay light and halogen, Gaona high bay light, etc.
How energy efficient are LED high bay lights? Learn about the comparison of LED high bay lamps and high pressure sodium lamps below.
1. Main features of LED high bay light:
1) The light source adopts a single high-power LED integrated light source, uses a unique multi-chip integrated single-module light source design, and selects imported high-brightness semiconductor chips. It has the characteristics of high thermal conductivity, small light decay, pure light color and no ghosting;
2) The unique integrated design of heat dissipation and lamp housing, which is perfectly combined with the electrical box, effectively conducts and diffuses heat, thereby reducing the temperature in the lamp body and ensuring the service life of the LED light source of 50,000 hours. According to the calculation of lighting 11-12 hours a day, the LED high bay light does not need to be replaced in 12 years.
3) The surface of the radiator is anodized and anti-corrosion treatment, the structure is compact and beautiful, and the anti-corrosion, waterproof and dust-proof performance is good;
4) The energy saving effect is obvious. The high-power LED light source is equipped with imported high-efficiency power supply, which can save energy by more than 70% compared with sodium lamps;
5) Green environmental protection and pollution-free, free of lead, mercury and other polluting elements, without any pollution to the environment; 7. Good color rendering, more realistic color rendering. Various light colors are optional, which can meet the needs of different environments, eliminate the depression caused by the high or low color temperature of traditional lamps, make the vision more comfortable, and improve the work efficiency of workers;
6) Using constant current and constant voltage control, the applicable voltage is wide (AC85V-265V), which overcomes the power grid, noise pollution and unstable lighting caused by the ballast, and avoids eye irritation and fatigue during work;
7) The decorative effect is excellent, the special surface treatment process is adopted, the appearance can be selected in a variety of colors, the installation is simple, the disassembly is convenient, and the application range is wide.
The LED high bay light uses ultra-bright LED white light as the light source, the shell is made of aluminum alloy (customer optional), the outer cover uses a high-efficiency lens (customer optional), and the heat dissipation adopts copper sheet heat conduction and aluminum alloy strips to dissipate heat and natural air circulation makes The heat dissipation is more perfect, and the shape will continue to change according to the different needs of customers. The power of LED high bay lamp is only 20% of that of sodium lamp, which is equivalent to 100W LED high bay lamp can replace 500W sodium lamp, especially in line with the "green and low carbon" proposed by the country. .
2. Main features of high pressure sodium lamps:
The high-pressure sodium lamp emits golden-white light when used, and has the advantages of high luminous efficiency, low power consumption, long life, strong fog-penetrating ability, and no insect trapping. When the power supply voltage of the high-pressure sodium lamp increases, the lamp power will increase greatly. 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 increase greatly. At this time, it is the time when too high illumination is not needed. Therefore, when SELB or LB is used to increase the power supply voltage, it is still Keeping the power of the bulb basically unchanged is very meaningful for energy saving, and also has a significant effect on prolonging the service life of the bulb and ballast.
3. Energy saving comparison between LED high bay light and high pressure sodium lamp:
1) Power density selection: the power density of traditional lamps is 10-25 watts/square meter, the power density of LED lamps can be designed at 3-15 watts/square meter, and the general office LED lamps are 3-10 watts/square meter. For occasions requiring high brightness, such as hotels, shopping malls, etc., it can be designed according to 10-15 watts/square meter.
2) Power selection: The power of LED high bay lamp is considered as 1/5 of the power of traditional high pressure sodium lamp.
3) Power factor: The power factor of LED lamps is above 0.95, while the power factor 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. Service life: The life of LED light source is 30,000-50,000 hours, while the life of traditional high-pressure sodium lamps 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 of LED high bay light and traditional halogen high bay light
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 Taiwanese manufacturers Epistar and Addison are also popular brands. In order to ensure the stability, cost performance and practicability of the product, we choose the well-known OSRAM chip as the light source for this high bay light.
Power options:
Compared with the characteristics of the 400W halogen lamp and the new LED high bay light, there are obvious differences between the traditional high bay light and the following table:
Considering the problem of halogen lamp decay and secondary light output in actual use, its actual luminous efficiency is lower than 30lm/W, often unable to reach the nominal 70%. Based on this, the power of the LED high bay light we developed for the first time is set to be about 150W. Once the lighting effect meets expectations, it will save more than 60% of energy compared with traditional lamps.
Cost and benefit assessment:
As we all know, compared with high pressure sodium lamps or metal halide lamps for workshop 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 into a lamp, the advantage of the strong directivity of the LED light source is easily reflected, and the efficiency of the LED lamp is much higher than that of the traditional lamp, so its energy-saving characteristics can be manifested clearly.
LED high bay light uses the 4th generation light source, which has the following advantages over other light sources, such as incandescent lamps, high pressure sodium lamps, high pressure mercury lamps, and electrodeless lamps:
Voltage:
The LED high bay light source uses a low-voltage power supply, and the single voltage is 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 laboratory has reached 161 lm/w (cree), which is the lighting product with the highest luminous efficiency at present. The theoretical luminous efficiency per watt of the LED is as high as 370 LM/W. Under the condition that the current chip structure does not change, a good process makes the LED reach 150 LM per watt without any problem. When this brightness is achieved, all lighting fields Basically it can be replaced. It is expected that in the next 1 to 3 years, the LED light source will reach a light efficiency of 300 lumens per watt. At present, the LED in the US laboratory has reached a light efficiency of 161 lumens per watt, and the total luminous flux is 175 LM.
Shock resistance:
LED is a solid-state light source. Due to its particularity, it has shock resistance unmatched by other light source products.

100,000 hours, the light decay is 70% of the initial
Response time:
The response time of LED lights is in nanoseconds, which is the fastest response time among all light sources at present.
Environmental friendly:
No harmful substances such as metallic mercury.
color:
The band speed of the LED is quite narrow, and the emitted color is pure, without stray light, covering the entire band of visible light, and can be combined into any desired visible light by RGB. Lifespan: The average lifespan of LEDs is 5000-100000 hours, which greatly reduces your maintenance and replacement costs.
