3. technical content

3.1 technical principle

By driving high-end electronic ballasts, the electric light source for gas discharge or solid (semiconductor) light emitting is stabilized from 220V AC at 50Hz to 400V DC, and then converted to 350V high-frequency AC (solid (semiconductor) light emitting The electric light source is stabilized to 400V~ 450V DC), and then converted into a high-frequency voltage of 40KHz to 50KHz to drive the light source. This technology overcomes the technical complexity of modern electronic ballasts and improves power conversion rates. After scientific light distribution calculation and design a special model of the principle of diffuse reflection, a rugged reflector was made. The luminescent characteristics of CFL and LED light sources are utilized to uniformly illuminate the uneven reflective material, and the light efficiency is increased through secondary and uniform diffuse reflection. The original high-quality light source can enhance the luminous efficiency, increase the illumination by more than 50% and reduce glare.

3.2 main innovations

(1) Modular technology of high-end electronic ballast for driving power supply. Overcome the technical complexity of modern electronic ballast, realize the fusion of digital and analog technology, ensure the reliability of the system, realize the functions of fault management, overvoltage (current) protection, automatic redundancy, etc., make the working voltage in 80V ~ 300V without being affected, the power factor reaches 99.9%, and solve the key problems of high working energy consumption and unstable voltage.

(2) Secondary diffuse reflection to increase light efficiency technology. Using a special nano-coating material with a high mirror reflectance of 99%, scientific light distribution calculation and design a special model of the principle of diffuse reflection, a reflector with uneven surfaces at 360 ° C was made to enhance the luminous efficiency and reflect the light quality on the back., it increases the illuminance by more than 50%, and the light source is transformed into a diffuse light source through diffuse reflection and solves the problem of glare.

(3) Diffuse light light source technology. The raw materials of the luminophore (light source) are improved, the luminous efficiency is increased, and the three-color green powder (lanthanum cerium terbium phosphate), red powder (yttrium europium oxide), and blue powder (barium magnesium aluminate) are purified to achieve high efficiency. Light emission solves the problem of luminous efficiency, making the luminous efficiency of bare lamp up to 240 lm/W.

(4) Innovation in transparent coating technology. Chemical silica water solvent is used as the coating medium for the rare earth three-color fluorescent powder of the light source part. It is resistant to high temperature of 1800 ° C, has a hardness of 9H +, and is resistant to weather and yellowing. It can make CFL and diode light source emitters play a certain role in slowing down light decay, solving the problem of rapid light decay of the light source.

4. Energy conservation and greenhouse gas emission reduction effects

At present, high-power sodium lamps and metal halide lamps are used in municipal street lights, tunnel lights, high-pole lights, and special lights for sports venues. They are high-energy light sources. The temperature generated during work is high, reaching 200 ° C to 400 ° C. The large current requires more auxiliary consumables (using a square wire). Diffuse lamp technology can replace sodium lamps and metal halide lamps, saving energy by more than 60%. A 100W diffuse light can replace a 250W sodium lamp (metal halide lamp), saving 150W, working 12 hours a day, 365 days a year, saving 657kW·h, reducing carbon dioxide emissions by 374.69kg, and saving energy annually. About 80.75kgce.

This is equivalent to saving 43.02 tons of standard coal every year.

(2) The street lights and tunnels of Cangnan National Highway 104 use diffuse lights. The original 400W sodium lamp, 1600 street lights and 600 tunnel lights, have been transformed into 160W diffuse lights. The annual energy conservation is 2.9434 million kW·h and the annual reduction is 1,678.6 tCO2, equivalent to an annual saving of 361.74 tons of standard coal.
