High-pressure sodium lamps compared with LED industrial and mining lamps?|Sunshinelux

January 10, 2023

How energy-efficient are LED high bay lights? Let's understand the comparison between LED industrial and mining lamps and high-pressure sodium lamps.

Main features of LED industrial and mining lights:

1. The light source lamp beads are all domestic famous brand 2835 SMD lamp beads, the internal Xiamen Sanan chip, the lamp bead bracket is made of PCT material, the luminous flux of a single lamp bead is 120-130lm, and the color rendering is above 80. The whole lighting effect is above 100lm/w.

2. Innovative heat dissipation technology: ADC12 aluminum alloy and other two different types of aluminum alloys are integrally formed through gear shaping and high-speed stamping processes, which can realize the heat generated by the light source being conducted to the stretched aluminum heat sink through the heat conduction uniform temperature plate, effectively Reduce the temperature of the LED light source, prolong the service life of the LED light source, and measure the pin position of the LED lamp bead, and the temperature rise is controlled within 40 degrees Celsius.

3. The main body of the radiator has undergone anodic oxidation treatment process and high-temperature spray powder and baking powder treatment, which can be applied to various industrial environments and places with weak corrosive gases. At the same time, the lamp body is made of stainless steel parts, which has strong corrosion resistance and is suitable for long-term use in relatively harsh environments.

4. LED lamps are equipped with Keming self-produced power supply, the circuit board is dipped in paint, and PET lining board is added to strengthen insulation protection. It ensures the safe insulation and stable electrical performance of the lamps, and can work in a wide voltage range (180-265V, 50-60Hz), and the output constant current accuracy is controlled within the range of plus or minus 5%. It can ensure the reliable and stable work of the LED light source.

5. The energy-saving effect is obvious, and it can effectively replace the traditional 75-250W metal halide industrial and mining lamps. Compared with traditional light sources, it can save more than 50% of electricity. It is a new type of industrial and mining lighting that is green, energy-saving, environmentally friendly, and free of heavy metal pollution.

6. Good color rendering, more realistic presentation of the actual color. A variety of light colors are available to meet the needs of different environments, eliminating the depression caused by the high or low color temperature of traditional lamps, making the vision more comfortable and improving the work efficiency of workers;

7. Excellent decorative effect, special surface treatment process, easy installation, easy disassembly, wide application range.

The heat dissipation adopts copper sheet heat conduction and aluminum alloy strip heat dissipation and natural air circulation makes the heat dissipation more perfect. The shape will continue to change according to the different needs of customers. The power of LED high bay lights is only 20% of that of sodium lamps, which is equivalent to 100W LED high bay lights that can replace 500W. Sodium lamps are especially in line with the "green and low carbon" proposed by the country.

Main features of high pressure sodium lamps:

High-pressure sodium lamps emit golden-white light when used, and have the advantages of high luminous efficiency, low power consumption, long life, strong fog penetration ability and no insect trapping. 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 increases a lot, and the lamp power and output luminous flux increase greatly. At this time, too high illumination is not needed, so 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 it also has a significant effect on prolonging the service life of the bulb and the ballast.
