LED lighthouse lights up Ottawa, Yantai upgrade lighting system, Shanghai customize light formula for plants.
LED lighthouse on the Ottawa National Art Center
To celebrate the 150th anniversary of Canada's founding, the National Art Center of Ottawa (NAC) has designed and installed a 50-foot transparent LED Media Wall customized by ClearLED. Its transparency is 80%, the maximum brightness is 8000 nite, allowing natural light to pass through. It can display different contents during the day and night. Four extra 32 foot high transparent LED films can coordinate the display of content and create unique aesthetic digital experience.
Upgrading of Yantai lighting system in Tashan tunnel
Recently, Yantai Tashan Tunnel lighting system upgrade and transformation work has begun, will be on July 7, two-way tunnel at the same time to implement half-enclosed construction.
Previously, the Tashan tunnel has been using the 150W sodium lamp as a light source, which not only has large calorific value and high power consumption, but also has low electro-optic conversion rate and poor illumination. Influenced by long-term heavy load transmission, lighting lines are aging seriously, and often short-circuit, circuit break and other faults, the quality of lighting is deteriorating. This upgrading is mainly to replace the larger load carrying cable to make the transmission more stable; the original lighting source is replaced by a LED light source with energy saving, environmental protection and better illumination, better to serve the vehicle and pedestrian lighting through the tunnel.
It is understood that the project started in June 21st, has completed the distribution box installation and other basic work. The renovation mainly demolishes the old line, lays the cable again 6129 meters, replaces the 120 WLED tunnel lamp 554 sets, is expected to be completed in mid-July.
Shanghai's first "aerosol culture" plant factory customized "light formula" for plants.
Shanghai's first "aerosol plant" plant custom-made "light formula" for plants.
Recently, the first "aerosol culture" plant factory in Shanghai attracted the attention of many participants at the 2008 Shanghai International Indoor Plant Workshop.
Plant plant is an efficient agricultural system for the continuous production of crop annual production through high precision environmental control within the facility. It uses computer to automatically control the temperature, humidity, light, carbon dioxide concentration and nutrient solution of plant growth, so that plants are unaffected by or restricted by natural conditions. Force type production mode.
According to the introduction, the plant plant uses the energy saving LED plant growth lamp as the light source. The light intensity, light quality and photoperiod are completely different for different plants and different growth stages. In vegetable factories, the growth of vegetables is hardly restricted by natural conditions, and the growth cycle will accelerate. The lettuce grown in the plant factory can be harvested about 28 days after transplanting, much faster than ordinary land cultivation.
At present, plant plants are in the initial stage of the world. It has fundamentally changed the concept of agricultural cultivation. It is the way to innovate agricultural cultivation and agricultural modernization. It is also the best scheme for new agricultural production and promotion of agricultural cultivation to manufacturing.
The development of the optical module of the LED headlamp for the MITSUBISHI motor
According to foreign media reports, MITSUBISHI Electric has developed a compact optical module that can provide high light output for LED headlights. The core component developed is a special system, which combines the focus lens and the projection lens to achieve more efficient LED headlights.
Although the new system is only 20 millimeters high, it can reach the same height as a large projection lens with 40 to 60 millimeters. The module has a good light distribution, the car manufacturer has great flexibility in design, increases driving safety and comfort, and reduces energy consumption. The above functions together make the module an ideal solution for the next generation of intelligent mobile travel.
The headlamp optical system collects the light projected from the LED light source, forming a beam, which is suitable for low light with clear and dark cut-off lines. Traditional headlight systems use reflectors with coated mirrors, which are easy to cause reflection loss, low efficiency and occupy more space due to their large size. The MITSUBISHI motor has developed an optical module for LED headlights, which aims to prevent other drivers and pedestrians from dazzling by providing the driver with superior visibility in order to improve the safety of the night driving. The module has compact structure, high luminous efficiency, advanced precise beam control function, and provides flexibility for automobile manufacturers to design.
