The lifespan of an LED cleanroom light is a critical factor in lighting planning. Unlike older light sources, which often fail abruptly, LED technology is characterized by high reliability and slow aging.

What affects the lifespan?

• Operating temperature: A lower operating temperature protects the LED chips and significantly extends the lifespan. Good cooling is therefore essential.
• Component quality: High-quality LEDs, drivers, and materials ensure longer life and consistently high light quality.
• Operating conditions: Frequent switching on and off significantly reduces the lifespan of conventional lights. This is no longer the case with LED technology.

How long does a DIANA cleanroom light last?

On average, you can expect a lifespan of 70,000 hours when used at room temperature. That equates to eight years of continuous operation, at the end of which the light still has 80% of its original light output.

Conclusion:

DIANA cleanroom lights are an extremely durable and energy-efficient lighting solution. By selecting the right light for your application, you can ensure a long lifespan and high reliability.

Additional tips:

• Pay attention to the protection rating (IP code): This indicates how well the cleanroom light is protected against dust and moisture.
• Choose the right light color: The color temperature affects the impact of the light and can influence the atmosphere in a space.
• Consider dimmability: Dimmable LED cleanroom lights offer additional flexibility in lighting. Reducing the operation also has a positive effect on the lifespan of LEDs.

No, it is generally not possible to repair the LED light source in a cleanroom light yourself.

Why is that?

• Sealing: To ensure a high protection rating (IP67) and to protect the light from environmental influences, our cleanroom lights are sealed tightly.
• Complex construction: The interior of a cleanroom light is complex and requires specialized tools and expertise for repairs.
• Safety risk: Improper intervention can lead to safety risks and void the warranty.

No, all of our cleanroom lights are specifically designed to provide flicker-free lighting. This is especially important when the lights are used in environments with moving parts, as stroboscopic effects can lead to dangerous situations.

Are there any exceptions?

In our D45-C series, slight flickering can occur in ECO mode under certain conditions. However, this mode is primarily intended for unattended operation, so the risk of injury from stroboscopic effects is generally very low.

Why is flicker-free lighting important?

• Eye strain: Flickering light increases eye strain, leading to fatigue and headaches.
• Safety: In industrial environments, stroboscopic effects can lead to accidents, particularly with rotating or fast-moving machine parts.

Conclusion:

Our cleanroom lights generally provide flicker-free lighting, making them ideal for industrial applications. If you have concerns or specific needs, we are happy to offer personalized advice.

The required power output of a cleanroom light depends on several factors and cannot be answered in general terms.

What factors are crucial?

• Distance from the illuminated surface: The greater the distance, the lower the illumination (lux level). Doubling the distance reduces the illumination on the surface to one-quarter.
• Beam angle: The beam angle of the light determines how wide the light cone is and how intense the light is in the center of the cone.
• Room size and shape: The size and shape of the room affect the distribution of light.
• Reflective surfaces: Bright surfaces reflect light and help achieve the desired illumination level.
• Additional light sources: Natural light and existing light sources in the room can be added to the desired illumination.

How do I find the right light?

• Isolux diagrams: In the datasheets for our cleanroom lights, you will find Isolux diagrams. These show you graphically how light is distributed across a surface and how the illumination level changes depending on the distance from the light.
• Personal consultation: We are happy to assist you in selecting the right light and creating a customized lighting plan. Book your free consultation now >>
• Lighting calculation software: For more complex lighting plans, we use specialized software tools for simulations. We can help you ensure the desired lighting with a simulation.

What else should be considered?

• Rule of thumb: If you double the distance from the light to the illuminated surface, the illumination is reduced to one-quarter.

• Light is additive: The light output of all lights in a room is cumulative.

Conclusion:

Selecting the right cleanroom light is an individual decision. To ensure optimal lighting, we recommend discussing the specific conditions of your project with us.

The maximum length of the connection cable depends on several factors and cannot be answered in general terms.

What factors are crucial?

• Cable cross-section: The larger the cable cross-section, the lower the voltage drop along the cable.
• Power consumption of the light: The higher the light's power, the greater the current flow and the stronger the voltage drop may be.
• Cable material: Different materials have different electrical resistances.
• Supply voltage: At lower voltages, the impact of the voltage drop is more significant than at higher voltages.

Rule of thumb:

For cleanroom lights with power consumption under 50 watts, a standard M12 connection cable up to 10 meters long is usually unproblematic.

Why is voltage drop important?

Too much voltage drop can cause the cleanroom light not to reach its full brightness or even fail.

How can I calculate the voltage drop?

There are special online calculators, like www.spannungsabfall.com, which you can use to calculate the voltage drop for your specific application.

Conclusion:

To ensure optimal functionality of your cleanroom light, it is important to choose the correct length and cross-section of the connection cable. If you are unsure, we recommend calculating the voltage drop or seeking advice from us.
