The bulb shall be firm and upright and shall not be loose or skewed. If the enamel umbrella is corroded or deformed major Solar Garden Light It needs to be replaced in time. Before using electric tools, please check whether the wiring, plug, socket, grounding and leakage protection devices are in good condition. Do not use them if they are damaged. Safety slogans, warning signs and safety operation instruction boards shall be set up on the construction site. Materials on the site shall be stacked orderly and stably and handled from top to bottom. When using hand-held electric tools, please wear personal protective equipment and the power cord should be empty. It is forbidden for non operators to use it on site major Solar Garden Light Power switches, wires and various mechanical equipment. Outdoor construction is not allowed in rainy season. Outdoor construction should be carried out after the rain is dry. The Quality Safety Department is responsible for preparing labor protection articles to ensure the safety of construction personnel.

Considering that street lamps are conductors, one way is major Solar Garden Light Combination of external lightning protection and internal lightning protection. As the material of street lamp is conductor, it is equivalent to lightning rod, and downlead and grounding grid need to be installed in the design. These systems constitute the external lightning protection system. After the completion of the external lightning protection system, the fire and personal safety accidents caused by the direct lightning stroke of the street lamp can be avoided. After the completion of external lightning protection, the internal lightning protection system can protect the equipment by grounding and setting voltage protection. major Solar Garden Light The internal lightning protection system is ready to prevent induced lightning and other forms of overvoltage intrusion, which may damage the power supply. This is also beyond the protection of external lightning protection system. Therefore, the built-in internal protection and external protection can complement each other.

There are many types of LED street lights, which can be classified according to the following categories. 1 major Solar Garden Light Height of street lights: high pole street lights, medium pole lights, street lights, garden lights, lawn lights; 2, according to major Solar Garden Light Material of lamp pole: hot-dip galvanized railway lamp, steel street lamp and stainless steel street lamp; 3. Divided by shape: Chinese lamp, antique lamp, landscape lamp, single arm street lamp, double arm street lamp. 4. According to the power supply mode: urban circuit light, solar street light, wind solar complementary street light.

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 Garden Light 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 Garden Light 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) Solar panel: 18v, 30-240wp monocrystalline silicon or polycrystalline silicon; (2) Controller: major Solar Garden Light Intelligent controller; (3) Battery: DC12V, 24V, lead-acid battery or gel battery, maintenance free; (4) Light source type: high-power LED integrated lamp head, die-casting aluminum material; (5) Light source power: 20-60W; (6) Light pole material: steel structure, hot-dip galvanizing, plastic spraying treatment; (7) Height: 6-8m; (8) Working time: 5-12 hours, 4-5 days in rainy days (different sunshine time in different regions); (9) Working temperature: - 35 ℃ - 65 ℃; In addition, major Solar Garden Light For the selection of solar panels and batteries, please refer to the purchase notes of solar street lamps. It can be seen that the selection of proper garden lamps is not only reasonable in price, but also comprehensive. In order to avoid unnecessary troubles.

one major Solar Garden 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 Solar Garden Light The use of crystal oscillator time control can make the time control more accurate.
