With the emergence of high brightness white LED light source, it is possible to apply it in the lighting field. According to the prediction of international authoritative organizations, the 21st century will enter the era of new light sources represented by LED, that is, the fourth generation of new light sources. major Multi function street lamp Its brightness is the same as that of traditional fluorescent lamps, and its color is gentle and easy to accept. The service life is 50000-80000 hours. When the bulb is started, it will open immediately and can be repaired when it is damaged (the traditional fluorescent lamp has been damaged and cannot be reused). It is not only very energy-saving, but also more environmentally friendly. major Multi function street lamp It is one of the main products promoted by the national green lighting energy-saving project, and is currently the first choice to replace the traditional high-pressure sodium lamp for industrial and mining lamps. At present, LED mining lamp has been used in many industrial enterprises, and its application effect is well received by customers.

one major Multi function 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 Multi function street lamp The use of crystal oscillator time control can make the time control more accurate.

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 Multi function 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 Multi function 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.

Main pole of high pole lamp: major Multi function street lamp When the height of the main pole exceeds 20m, the steel plate with a wall thickness of 5.6mm is usually used as the main material. After the overall welding of the high pole lamp, the internal and external surface layers need to be hot-dip galvanized and qualified galvanized. This process can ensure that the main pole will not rust for 15 years. Lifting system: the lifting system is regarded as the core part of the high pole lamp. The landing action of the light panel depends entirely on the landing system. The landing system of high pole lamp is mainly hoist and wire rope. First, install the elevator on the main rod. Weathering and rain will not cause line aging. Secondly, the hoist seldom starts. If major Multi function street lamp If the light source has not been damaged in ten years, it will not need to be touched in ten years. Lamp cap: Whether it is LED lamp cap or low pressure sodium lamp, the light source is the main symbol of the whole set of high pole lamp. If the light source is broken and the high pole lamp is broken, the selection of light source quality is particularly important.

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 Multi function street lamp 。 2. Energy conservation and environmental protection. Beijing major Multi function street lamp 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.
