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 Solar street lamp 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. Dongguan major Solar street lamp Discontinuous and uneven. For drivers of high-speed vehicles, this kind of light dark alternation will cause visual illusion, which is very dangerous.
one major Solar street lamp 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 Solar street lamp The use of crystal oscillator time control can make the time control more accurate.
install major Solar street lamp The construction site shall be provided with safety slogans, warning signs and safety operation instruction boards, which shall not be removed or moved at will. Any movement shall be approved by the person in charge of site construction. When working on site, please pay attention to vehicle access and mechanical lifting. During normal construction, there should be no less than 2 people, and when there is only one person on site, no operation is allowed. Obey the instructions of on-site construction personnel, obey the assignment, unite and complete the production task. Materials on site shall be stacked neatly, and hazardous materials, chemical reagents and flammable materials must be placed separately. It is strictly prohibited to work in flammable and explosive places, open fire, smoking, etc. In operation major Solar street lamp Before that, please check whether the operation site is safe, whether the road is unblocked and whether the protective measures are complete. The tools used should be restored after the work is completed. Please wear safety belt when working at heights, cliffs and steep slopes without protective facilities.
The life of LED mining lamp depends largely on the level of heat dissipation, and the main way to improve the level of heat dissipation is to transfer the excess heat generated by the chip through the radiator and radiator. At the same time, major Solar street lamp The main parameters related to LED heat dissipation are thermal resistance, junction temperature, temperature rise, etc. Thermal resistance is the quotient obtained by dividing the difference between the effective temperature of the equipment and the temperature of the external designated reference point by the steady-state power consumption in the equipment. It is an important parameter indicating the degree of heat dissipation of equipment. Junction temperature refers to the temperature of the semiconductor junction of the main heating part in the LED device. It reflects major Solar street lamp Temperature value that can be withstood under working conditions. Temperature rise refers to the temperature rise of the enclosure environment. It refers to the difference between the temperature of LED equipment shell and the ambient temperature. This is a temperature value that can be directly measured, which can directly reflect the heat dissipation degree around LED devices.
1、 Disconnection. For "dead light", we should first determine major Solar street lamp Is it short circuit or open circuit. 2、 The adhesive layer is peeled off. For some LED energy-saving project lights with vertical chips, the common reasons for dead lights are the peeling off of the bottom of the chip bonding layer and the peeling off of the bracket coating. 3、 The welding spot is burnt. In some cases, the dead light of the bulb may not be caused by the bulb itself, but also by the power supply used. 4、 Chip corrosion. The previous energy-saving floodlights and energy-saving floodlights are open circuit. The following is the condition of short circuit dead light. major Solar street lamp There are many reasons for dead lights. Dead light may appear in every link from packaging, application to use.
