LightSources offers innovative low-pressure amalgam lamps custom-engineered for industries seeking efficient and reliable germicidal solutions.

Introduction to Low-Pressure Amalgam Lampslow pressure amalgam lamps

Ultraviolet (UV) germicidal technology harnesses the power of UV light to deactivate the DNA of bacteria, viruses, and other pathogens, preventing them from multiplying and causing disease. This technology is crucial in a variety of applications, ranging from water purification to air and surface disinfection. Within the spectrum of UV germicidal solutions, low pressure amalgam UV lamps represent a significant advancement, enhancing the efficiency and output of traditional UV disinfection methods.

Amalgam UV light technology plays a pivotal role in this advancement by increasing the power density and electrical efficiency of UV lamps. These amalgam UV bulbs utilize an amalgam, an alloy of mercury with other metals, to optimize UV output at a broader range of operating temperatures compared to standard low pressure UV lamps. This makes low pressure amalgam lamps particularly effective in environments where maintaining consistent UV output is challenging due to fluctuating temperatures.

What is Amalgam Lamp Technology?

Amalgam technology refers to the use of an amalgam—a solid solution or alloy of mercury with one or more metals—as the primary means of enhancing UV light output in low pressure UV lamps. This technology is critical in extending the operational stability and efficiency of UV lamps across a broader temperature spectrum. In the context of UV germicidal lamps, amalgam is used to maintain a more consistent vapor pressure of mercury within the lamp, which is crucial for sustaining optimal UV output.

Pellet and Spot Amalgam Technologies

In the realm of amalgam UV lamps, there are primarily two types of technology: pellet and spot amalgam. Pellet amalgam technology, a significant innovation developed and patented by LightSources in the United States and by LightTech in Europe, offers several advantages over the traditional spot amalgam approach.

Low pressure amalgam lamps are designed to produce higher UVC output at full power and under varying power conditions, such as dimming scenarios. This capability allows for more effective germicidal action across a range of environmental conditions and power settings.

low pressure pellet amalgam lampsDifference between Pellet and Spot Amalgam

The primary difference between pellet and spot amalgam technology lies in their configuration and performance under different operational stresses. Pellet amalgam, consisting of small, compact pellets, provides a larger surface area for the mercury amalgam, enhancing the lamp’s efficiency and power stability. In contrast, spot amalgam typically involves a smaller amount of amalgam placed at specific points within the lamp, which can limit performance flexibility and overall UV output efficiency.

By utilizing pellet amalgam technology, LightSources’ lamps achieve greater UV intensity and maintain higher energy efficiency, making them ideal for critical applications in water and air purification systems where reliability and high performance are essential.

LightSources’ Proprietary Pellet Amalgam Technology

Low Pressure Amalgam Lamps 1LightSources and its European partner, LightTech, have developed and patented an advanced form of UV lamp technology known as pellet amalgam. This innovation represents a significant leap forward in UV germicidal efficacy and operational versatility. Pellet amalgam technology utilizes small, compact pellets of amalgam rather than the traditional spot amalgam, which places the amalgam at specific points within the lamp. This method optimizes the distribution and efficiency of the mercury vapor within the lamp, crucial for generating consistent ultraviolet light.

Benefits of Pellet Amalgam Over Spot Amalgam:

  1. Higher UVC Output: Pellet amalgam lamps are capable of producing higher UVC output both at full power and under varied power conditions. This makes them more effective in germicidal applications, especially under dimming conditions where spot amalgam lamps might falter.
  2. Versatile Mounting and Environmental Adaptability: Unlike traditional UV lamps, pellet amalgam lamps maintain high efficiency regardless of their mounting orientation—horizontal, vertical, or diagonal. They are also designed to perform optimally in a wide range of ambient environments, making them ideal for use in diverse operational settings where temperature and mounting flexibility are factors.
