one major Plant lighting 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 Plant lighting The use of crystal oscillator time control can make the time control more accurate.

1. Be able to monitor the temperature of the light source chip pad of the street lamp itself or the temperature of the lamp shell and conduct fault diagnosis; 2. Remote measurement of electrical parameters such as street lamp current and voltage, remote switching of street lamps, remote viewing of on-site operation of important road sections, etc; 3. According to major Plant lighting The monitoring data of can timely grasp the abnormal position and reason of street lights, and carry out purposeful maintenance without having to go to the whole city for inspection, which speeds up the speed. 4. It has daylight sensor or on-board sensor dimming, energy saving control, time control and even RTC dimming; 5. In some areas with few people and vehicles, it can be controlled at half bright time in the middle of the night, but when people and cars pass by, major Plant lighting They will reach the distance ahead and in a few cases restore the original brightness. Seconds. 6. The lighting standard level of the same road will change with time and traffic flow.

1. Energy saving economy. First, each solar street lamp is a relatively independent system. In the process of installation and construction, there is no need to lay cables or dig roads, thus saving a lot of manpower, material resources and installation costs; In addition, it also consumes electricity, and ordinary street lights are on all day. The lamp lasts about 6 hours, consumes about 2 kWh, and the annual electricity charge is more than 300 yuan. According to 300 street lights in the urban area, the annual cost is nearly 100000 yuan. Can be saved major Plant lighting 。 2. Energy conservation and environmental protection. Texas major Plant lighting It is mainly composed of four departments: photovoltaic module, light-emitting diode, solar cell and controller. Photovoltaic modules absorb light in the daytime, convert solar energy into electric energy, store it in solar cells, and release illumination when it turns dark at night.

major Plant lighting Coordination of color temperature and illuminance. The color temperature of light source is the color expression of light, major Plant lighting 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.

Computer modeling is used to simulate the luminous angle of the reflector light source and the spatial structure of the LED reflector, track the refraction track of light, and adjust the curvature of the reflector to achieve the light intensity distribution of the reflector The functional requirements of the LED light beam angle are greatly improved major Plant lighting The light efficiency of the reflector reduces the possibility of astigmatism and glare. The reflective surface can be plated with orange peel and smooth. It can be more uniform and soft, without black holes, yellow circles. High reflection efficiency, no layering, high temperature resistance. The frosted mirror gently reflects light, which is suitable for occasions with weak light such as supermarkets and shopping centers. major Plant lighting It is not applicable to places with high illumination requirements such as industries and stadiums. If it is used for industrial lighting, it needs a reflector with high refraction and luminous efficiency, and when the light passes through the reflector, it must reduce the light loss.

Reason 1: The cost of installing street lights on expressways is very high, and the installation distance of street lights is generally 30 meters to 40 meters. If the 50 meter street light is regarded as hundreds of kilometers on any expressway in China, the street light will be installed. major Plant lighting The cost is very high. The second reason is that the expressway has a high safety factor. The expressway is a closed road connecting the city and the city. In the absence of pedestrians and non motorized vehicles, urban street lights are designed for the safety and convenience of non motorized vehicles and pedestrians. Third, automobile headlights and road reflective signs are sufficient to meet the lighting needs. Texas major Plant lighting Discontinuous and uneven. For drivers of high-speed vehicles, this kind of light dark alternation will cause visual illusion, which is very dangerous.
