High pressure sodium lamp and LED high bay light (led factory light)

March 03, 2023

At present, LED industrial and mining lamps have been popularized and applied in the world, but there are still many manufacturers who have not found a good solution for the heat dissipation of high-power LED industrial and mining lamps. With the wide application of LED industrial and mining lamps, the power of LED industrial and mining lamps has also been Higher requirements; this means that the thermal conductivity of LED high bay light is a problem that must be solved; currently the single heat conduction of aluminum has met the heat conduction requirements of LED high bay light. The inefficient conduction of heat will also affect the life of the lamp. Similarly, for enterprises, cost savings can not be achieved very well. LED industrial and mining lamps do not take long to reach the normal lighting needs because of the light attenuation, so they have to change the lights; The company that saves electricity costs and replaces the lights is not to lose.

How much energy is the LED high bay light? Today, the first LED network brings you to understand the comparison between LED high bay light and high pressure sodium lamp:

Main features of LED high bay light:

LED high bay light is made of super bright LED white light as the light source, the shell is made of aluminum alloy (customer optional), the outer cover is made of high efficiency lens (customer optional), the heat dissipation is made of copper sheet heat conduction and aluminum alloy strip heat dissipation natural air circulation The heat dissipation is more perfect, and the shape of the LED will be changed continuously according to the different needs of customers. The power of LED high bay light 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 national “green low carbon” .

Main features of high pressure sodium lamp:

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 fogging ability and no insect attracting. When the power supply voltage of the high-pressure sodium lamp rises, the lamp power will increase greatly. If 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, the lamp power and output light flux increase greatly, and at this time, it is not necessary to have too high illumination, so when SELB or LB is used to increase the power supply voltage, Maintaining the lamp power is basically the same, which makes sense for energy saving, and also has a significant effect on extending the life of the bulb and ballast.
