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 City circuit 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 City circuit 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) 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 City circuit lamp 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 City circuit lamp 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.

At present, there are basically two kinds of sensors used for parking lot lighting. One is infrared sensor, which is relatively cheap. However, due to the height of the floor, the limitation of the metal tube and the influence of the radiation angle, the infrared sensor has a certain detection blind spot. The other is a microwave sensor, which can overcome the disadvantage of detecting corner blind areas, but the price is higher. These two sensors and major City circuit lamp Combined, the lighting energy saving of the underground parking lot is effectively realized. When someone moves the car under the light, major City circuit lamp It will run at full speed to meet the lighting demand. When there is no car and no car, the lamp is in a sleep state, and low power lighting of about 3W is maintained to maintain the required safety lighting. Low illumination, realizing energy saving of lighting.

The bulb shall be firm and upright and shall not be loose or skewed. If the enamel umbrella is corroded or deformed major City circuit lamp 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 City circuit lamp 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.

LED panel light is a point shaped illuminant, which brings creative visual effects through the flexible design of points, lines and surfaces. It is light and thin, and can be installed on the ceiling, wall and the surface of the installation body, and suspended under the ceiling or the installation body. According to customer requirements, we can design light sources with different shapes and particles, which are flexible in design. High brightness major City circuit lamp Light source, quick start, natural and soft light. It belongs to the category of lamps with strong anti vibration ability. The light source is a high hardness resin illuminant rather than tungsten glass, which is not easy to be damaged. Therefore, it has high anti vibration ability and strong adaptability to ambient temperature. major City circuit lamp The uniform luminous reflective plate and sealed internal design are adopted, which are combined with the light guide plate and made of aluminum alloy materials. The effect is uniform and the lighting range is larger.

If there is a problem with the solar street lamp in the countryside, first check whether the photocell is correctly connected, whether the wiring position is in poor contact, and then check whether the battery connection is correct and whether the battery voltage is normal. If the battery is excessively discharged, a fault will occur and it will automatically recover after being fully charged. Among them, major City circuit lamp The stability of the controller is very important for the service life of rural solar street lights, because the role of the solar controller is to control the use major City circuit lamp The battery board charges and discharges the battery. When choosing a solar cell, you must choose a high stability battery to ensure the service life of the battery, because the quality of the battery will also directly affect the service life of the street lamp. It can extend the service life of the whole rural solar street lamp.
