one major Cast light The charging circuit adopts a dual MOS series control circuit, which can reduce the voltage loss of the circuit by nearly half compared with the use of diodes. The use of PWM energy-saving control greatly increases the power consumption. 2. The load mode adopts pure light control. When the light is dark, the light sensor system will automatically light up. 3. Scientific battery management method. When over discharge occurs, the battery voltage will promote charging. After maintenance and compensation, it can be used normally. Direct charging and floating charging are used to connect rechargeable batteries. 4. All restrictions of all industrial chips and closed components can operate normally in cold, high temperature and humid environments. At the same time, major Cast light The use of crystal oscillator time control can make the time control more accurate.

Using the integrated technology of LED electro-optic source, according to major Cast light The characteristics of semiconductor luminescence, ingenious circuit design and unique lighting geometric appearance, major Cast light It can save more than 80% of electricity, realizing effective energy saving. The ultra long service life is up to 50000 hours, which can be used well in various special environments (such as low temperature and high temperature conditions). It solves the problems of low power and insufficient brightness of semiconductor electric light source in the lighting field, and shows excellent high brightness characteristics. There is no need for ballast, no starting difficulty, complete overcurrent, overvoltage, short circuit, temperature, surge protection, and its lighting optical performance is brighter and more complete than 75W/400W/1000W metal halide lamp.

major Cast light Coordination of color temperature and illuminance. The color temperature of light source is the color expression of light, major Cast light The psychological effects of light color on people include cooling and heating effects and other expansion effects. The cooling and warming effect is based on the blue-green and red orange as the two extremes of "cold color" and "warm color". It is generally believed that red has a warm feeling, while cyan has a cold and muddy feeling. The color temperature should be selected to achieve the desired lighting effect as to what kind of nightscape environment atmosphere needs to be created. The influence of color temperature on people is not only the feeling of cold and warm, but also the environmental illuminance. At low illumination levels, warm light with low color temperature is more acceptable, while at higher illumination levels, cool light with higher color temperature is more popular.

(1) There are potential safety hazards in municipal lighting: due to the construction quality, garden engineering transformation, aging materials, abnormal power supply, water and electricity pipeline conflict, many potential safety hazards have been brought. (2) Solar street lamps are energy-saving and environment-friendly new energy power generation products. There is no electricity bill. High electricity charge for mains lighting: major Cast light Our jobs have fixed and high electricity bills. Solar lighting is free of electricity charge: solar road lighting is a one-time investment without any maintenance costs, the investment cost can be recovered within three years, and has long-term benefits. （3） major Cast light The installation of the solar street lamp is very simple: when installing the solar street lamp, you don't need to lay complex lines, just make a cement base and fix it with stainless steel screws. The installation of municipal lighting fixtures is very complicated: there are complex operating procedures in the municipal lighting project.
