Advantages of Tubular Daylighting Systems over Traditional Lighting

Tubular daylighting systems offer numerous advantages over traditional lighting fixtures. Here are the main benefits:

1. Working Principle

   • Traditional Lighting: Converts electrical energy or other power sources into light energy.
   • Tubular Daylighting: Utilizes natural light sources and conducts light to areas requiring illumination through optical principles.

2. Usage Effects

   • Traditional Lighting: May generate side effects such as heat, noise, and radiation.
   • Tubular Daylighting: Does not produce these side effects and provides even, natural light.

3. Maintenance Costs

   • Traditional Lighting: Requires regular bulb replacement and cleaning of fixtures.
   • Tubular Daylighting: No need for regular light source replacement, and cleaning is relatively straightforward.

4. Installation Difficulty

   • Traditional Lighting: Involves wiring, drilling, and electrical safety considerations.
   • Tubular Daylighting: Easier to install, requiring only the arrangement and securing of the tubes.

5. Applicable Places

   • Traditional Lighting: Suitable for situations requiring high brightness and long usage hours.
   • Tubular Daylighting: Ideal for indoor spaces that need improved lighting but cannot install windows or skylights.

6. Health and Environmental Protection

   • Traditional Lighting: May contain short-wavelength blue light, which can damage the retina.
   • Tubular Daylighting: Uses natural light sources, offering a high-quality lighting experience, reducing blue light harm, and providing full-spectrum, glare-free, flicker-free light.

7. Energy Saving and Economic Benefits

   • Traditional Lighting: Consumes electrical energy, leading to high long-term costs.
   • Tubular Daylighting: Brings natural light indoors, reducing reliance on artificial lighting, thus saving energy and reducing energy costs. A one-time investment with a payback period of 3-5 years, a product lifespan of up to 25 years, no operational costs, and no maintenance required.

8. Green Building Points

   • Traditional Lighting: Does not meet green building assessment standards.
   • Tubular Daylighting: Complies with the updated "Green Building Assessment Standard" GB/T50378-2019, which includes requirements for indoor environmental quality, daylighting, and views. It improves the natural lighting effects within buildings, contributing to green building points.

In summary, tubular daylighting systems outperform traditional lighting in various aspects, particularly in health, environmental protection, energy saving, and economic benefits.
