USHIO 100W USH-103D Hg 100W Short Arc Mercury Medical Lamp

USHIO 5001329 100W USH-103D Hg 100W Short Arc Mercury Scientific Medical Lamp

The Ushio 5001329 USH-103D is a high-pressure mercury arc lamp commonly used in projectors, microscopes, and scientific equipment requiring intense and focused light. Known for its high brightness, UV output, and long life, this bulb is typically used in UV curing, fluorescence, and photolithography applications, as well as in specialized optical and imaging systems.

Ushio 5001329 USH-103D, Hg 100W Hg 100W Technical details:

1. Lamp Type: Mercury Short Arc Lamp
   The USH-103D is categorized as a DC mercury short arc lamp, meaning it has a tightly focused arc with a high-pressure mercury vapor inside. This design produces intense UV and visible light and is ideal for applications needing concentrated illumination.

2. Operating Voltage and Current:
   The lamp typically operates at 19 volts and 5.4 amps DC. This consistent voltage and current are essential to maintain stability in brightness and UV output. A constant current DC power supply is recommended to avoid fluctuations that can destabilize the arc.

3. Power Consumption:
   It operates at 103 watts, providing a high level of light intensity relative to its size, which makes it suitable for compact devices like projectors or imaging systems.

4. Color Temperature:
   This bulb has a color temperature of 5,800 K, producing a bright, daylight-like output. This high color temperature is crucial for applications requiring high color accuracy and clarity, like in microscopy and fluorescence imaging.

5. UV Output:
   Due to its high UV output, the USH-103D is particularly effective for UV-sensitive applications like photolithography, fluorescence, and curing processes. It emits substantial energy in the UV-A and UV-B spectrums, critical for processes that require UV reactivity.

6. Lifespan:
   The typical lifespan is 300 hours under optimal conditions. Because of its high intensity and UV output, this is a relatively short lifespan. Proper handling, cooling, and consistent power can help achieve the full lifespan.

7. Operating Position:
   These lamps generally have a specific orientation for optimal operation (often specified in manuals), usually “base down” or horizontal. Using it in the wrong orientation can result in uneven brightness, premature failure, or reduced lifespan.

8. Arc Gap:
   The arc gap is very small, allowing for a focused and intense light source, which is beneficial for precision lighting applications. This short gap contributes to the high luminance and compact, efficient design.

9. Cooling Requirements:
   As a high-pressure lamp, it generates significant heat, necessitating effective cooling to maintain performance and avoid overheating. An active cooling mechanism, such as forced-air ventilation, is often required.

10. Application-Specific Reflector Compatibility:
    In certain configurations, it is paired with custom reflectors or lenses to direct light precisely. The high intensity and focused nature of this bulb make it an ideal candidate for use in systems that require concentrated light in a specific direction or area.

The USH-103D is well-suited for various scientific and industrial uses, especially where accuracy, intense illumination, and UV are essential.
