The result of the bidding for the LED lighting (including light source) procurement project in the southern section of the first phase of Hangzhou Metro Line 4 was recently announced. Hangzhou Hongyan Electric Appliance Co., Ltd. (hereinafter referred to as “Hongyan Electrical Appliancesâ€) successfully won the bid, and the winning products included flat panel lights, downlights, and three. LED lighting products such as anti-lights and special-shaped lamps have a winning bid of 12.45 million yuan.
The first phase of Hangzhou Metro Line 4 is a key construction project in Zhejiang Province. The route is laid along the Puyan Road-Dongxin Avenue-Fuxing Road-Fuchun Road-Qingchun East Road-Xintang Road-Tiandong East Station. The final destination ends at Qibao. The depot has a total length of about 20.8 kilometers. All of them are underground lines, with 18 stations and 1 parking lot (Jubao Parking Lot) with a total investment of about 140.19 billion yuan.
The bidding includes Puyan Station, Yangjiadun Station, University of Traditional Chinese Medicine, Lianzhuang Station, Shuicheng Bridge Station, Fuxing Road Station, Nanxingqiao Station, Qijiang Road Station, Jiangbei Fengjing (Lianzhuang Station Station ~ Shuicheng Bridge Station) Well lighting fixtures and Puyan station - near river station (excluding) section tunnel lighting.
Tunnel lighting fixtures are different from ordinary lighting fixtures, and they are strictly required in terms of materials and technology. According to the relevant technical personnel of Hongyan Electric, the various lighting products used in this bidding adopt aluminum alloy lamp body, anodized aluminum plate reflector and tempered glass as hoods, which achieve the double effect of national A-level fireproof and environmental protection; external electrostatic spraying Or oxidation process, so that the appearance of the lamp looks neat, beautiful, bright, and does not change color and corrosion.
In addition, the luminaire adopts a unique structural heat dissipation, and the heat generated by the light source is quickly transmitted to the lamp body through the high heat conduction aluminum substrate, and then the heat convection and radiation heat dissipation are performed through the outer surface of the lamp, thereby effectively ensuring the heat dissipation path and making the service life of the lamp exceed 50,000 hours, and in the installation of the luminaire, Hongyan adopts a safe and reliable mechanical structure, which meets the vibration and wind pressure requirements of the interval tunnel impedance train to prevent the lamp from accidentally falling off.
Tunnel lighting has special requirements for anti-stun. It is worth mentioning that, from the beginning of the project, Hongyan lighting products will be integrated into the whole product development process as an important indicator for preventing glare. The product adopts a unique wide light distribution curve design, which can avoid eye discomfort caused by front view and squint light source. .
