  • Q
    Who is Eastview?
    A

    Beijing Eastview New Energy Technology Co., Ltd. was established in December 2005.It is a A high-tech enterprise that produces Tubular Daylighting System. The company is the national building lighting design standard participating unit and passed the ISO9001 national quality system certification.

    Brought in the foreign advanced technology, and combined with the actual situation in the country, and intensified research and development, we broke through a series of technical bottlenecks of domestic architectural lighting, and independently developed and produced the "SUNTUBE® "Tubular Daylighting System.

  • Q
    What’s “SUNTUBE®” Tubular Daylighting System?How it works?
    A

    There are three main ways to use solar energy: solar thermal utilization (solar water heaters), solar photovoltaic conversion (photovoltaic power generation), and direct sunlight utilization (Tubular Daylighting System). The Tubular Daylighting System is also called tubular skylight system, suntube,skylight tunnel, solar skylight,non-electrical lighting and so on.

    The Tubular Daylighting System capture natural light through the outdoor light collector without electric. After being efficiently reflected and transferred by the tube, the diffuser can evenly deliver natural light into the room where light is needed.

Product
  • Q
    What’s the height from roof to dome(light collector)?
    A

    Cement roof:Reserved hole 250mm higher than roof

    Slope roof:model DS530 225mm higher,DS450mm higher than roof

  • Q
    How’s the strength of the dome(light collector)?
    A

    The dome is made of high quality PC material imported from abroad and added with UV and injection molding. It is safe and has no odor. It can insulate more than 90% of ultraviolet rays, and the yellowing index of the dome is greatly improved due to the addition of UV material, and the yellowing performance is less than 1. In addition, the PC material itself has strong abrasion resistance and impact resistance, can withstand various impacts, and has a firm structure and high toughness.

Installation
  • Q
    How long does it take to install a system?
    A

    The whole structure of the system has been partially fixed in the factory, and it is easy to install.It will take about 2 hours to install with a skilled worker.

  • Q
    What’s the preparation work before install the system for customer?
    A

    The customer needs to provide the general building plan, indicating the selected area to use system and the required illuminance value. Professional designers will select the product and drawing points and reserved hole.
