   Explosion-proof lamps are those lamps like metal halide lamps or high-pressure sodium, because this type of lamps and lanterns are high-pressure and high-temperature nature, there is a certain danger, and this kind of lamps and lanterns will be much safer to make explosion-proof.        But LED luminaires are different, they are cold light sources and there is no danger of breaking or exploding. So why should LED lamps be made explosion-proof? What is the difference between it and ordinary LED lights?      Explosion-proof lamps are mainly used in hazardous places where flammable gases and dusts are present to prevent combustion or explosion caused by arcing, sparks and high temperatures generated inside the luminaire. Avoid the activation of flammable gases and dusts in the surrounding environment due to the combustion or explosion of the lamp, so as to meet the explosion-proof requirements of the lamp. Explosion-proof lamps are also called explosion-proof lamps, explosion-proof lighting street lights, LED explosion-proof lights, and so on. Different flammable substances and gas mixtures have different requirements for the type and grade of explosion-proof lamps.        LED explosion-proof lamps and ordinary lamps can be intuitively seen from the surface, and most of the explosion-proof lamps are yellow in color (not excluding a few other colors). In terms of weight, the explosion-proof lamp is much heavier than the ordinary lamp, because the heat dissipation aluminum used in the explosion-proof lamp is thickened, in order to prevent the internal constant current source from being damaged to the protective shell after the problem. The explosion-proof types of conventional explosion-proof lamps are as follows.   1.Increased safety type e    Under normal operating conditions, the electrical equipment that will not produce arc and spark takes some additional measures to improve its safety, prevents its internal and external parts from having the possibility of dangerous temperature, arc and spark explosion-proof type, and further takes protective measures in the structure to improve the reliability performance and safety performance of the equipment. 2.Positive pressure type p    Electrical equipment protects static positive pressure inside the system or maintains a continuous flow of air or inert gases to limit the entry of flammable mixtures into the enclosure by keeping the pressure of the shielding gas inside the enclosure higher than the ambient explosion-proof atmosphere pressure to safety. Remove the flammable gases that enter the housing when the equipment is not under positive pressure to prevent the formation of flammable mixtures in the housing. 3.Pouring type m    The electrical parts that may produce the spark, arc or dangerous temperature part that ignites the explosion of explosive mixture, are poured in the encapsulant (compound), so that it can not ignite the surrounding explosive mixture, adopt the pouring measures, can prevent the short circuit of electrical components, solidify the electrical insulation, avoid the spark on the circuit and the ignition of arc and dangerous temperature, prevent the invasion of explosive mixture, and control the surface temperature under normal and fault conditions. 4.Oil-filled o    The whole equipment or parts of the equipment are invaded in the oil I protective fluid l, so that it can not be ignited above the fuel level or outside the explosion-proof gas environment outside the shell. 5.Sand filling type Q    The protective type of electrical equipment in which the shell is filled with sand particles or other powder materials with specified characteristics, so that under the specified conditions of use, the arc or high temperature generated in the shell cannot ignite the surrounding explosive gas atmosphere.   Due to the different requirements for explosion-proof lamps in different environments, it is important not to choose explosion-proof lamps casually, but to choose the corresponding model according to specific requirements.

1. Choose LED lighting fixtures with lumens/watt height   Luminous flux, which is the total amount of visible light emitted by a light source per unit of time, in lumens (Lm). Luminous efficiency, i.e., the amount of light energy emitted per watt of electrical power produced by a light source (commonly known as luminous flux), unit: lumens per watt (Lm/w)   The comprehensive luminous effect of LED lighting fixtures refers to the luminous efficiency of a finished LED street lamp. Under the rated voltage, the total luminous flux emitted by the LED lamp is divided by the total power consumption of the LED lamp, that is, the comprehensive luminous efficiency of the LED lamp, expressed in lumens/watt, the higher the value, the better the energy-saving effect of the lamp, the more power saving. Under the same power, the lamps with high luminous efficiency and large luminous flux are brighter and more energy-saving! A 3W LED bulb is taller than an 18W energy-saving lamp. And the ratio is about 8 times that of a 40W incandescent lamp. 2. Choose products with high color rendering index   Color rendering refers to the degree to which the color of an object is close to the true color when illuminated by light. The higher the Ra value of the color rendering index, the closer the color of the object will be to the true color. It is generally believed that 80~100, excellent color rendering; 50~79, general color rendering:

    Solar street light is an environmentally friendly and energy-saving lighting device that uses solar energy to generate electricity, store electrical energy, and illuminate at night. It uses solar panels to absorb daylight, convert it into electricity, and store it in batteries, thus realizing the function of night lighting. Its endurance mainly depends on the photoelectric conversion efficiency of the solar panel, the energy storage capacity of the battery and the stability of the charging system.      1.The photoelectric conversion efficiency of solar panels is one of the key factors affecting the endurance of solar street lights.The higher the photoelectric conversion efficiency, the more efficiently the solar panels can absorb daylight and convert it into electricity, thus providing more sufficient power support for night lighting.At present, the photoelectric conversion efficiency of solar panels on the market has been quite high,which can reach more than 20%, which ensures that the solar street lights can be fully charged during the day and provide continuous lighting for the night.      2.The energy storage capacity of the battery is also one of the important factors affecting the endurance of solar street lights.   It is responsible for storing the electrical energy converted by solar panels during the day and providing it to LED lights at night or when there is low light. The larger the energy storage capacity of the battery, the more electricity can be stored, thus extending the use time of solar street lights. The types of solar street lamps of different models and brands are also different, and the common ones are lead-acid batteries, lithium-ion batteries and lithium cobalt oxide batteries. The power and performance of these batteries also vary, affecting the lifespan and lighting effect of solar street lights.   The battery of the solar street light can be replaced, but it needs to be determined on a case-by-case basis. First and foremost, the life of the battery is a factor to consider. With the increase of use time, the capacity of solar street light batteries will gradually decrease, affecting the lighting effect of the lamp. When the battery capacity drops to a certain extent, it is necessary to consider replacing the battery to ensure the normal operation of the street light. Secondly, the maintenance of the battery needs to be considered. Solar street light batteries need to be checked and maintained regularly, including cleaning the dust and dirt on the surface of the battery, checking the connection and charging and discharging performance of the battery, etc. If the battery is severely aged, damaged, or degraded, it is time to consider replacing the battery to ensure proper operation. Finally, pay attention to the model and specifications of the battery. Different brands and models of solar street lights may use different batteries, so you need to choose the right battery model and specifications when replacing the battery to ensure compatibility and proper operation.    3.The stability of the charging system will also have an impact on the battery life of the solar street lights.    The stable charging system can ensure that the solar cells can fully absorb the sunlight and store the electrical energy into the battery in time, so as to ensure that the solar street lights can work normally. When designing solar street lights, it is necessary to consider the intelligent control functions of the charging system, such as light control,time control, temperature control, etc., to improve the charging efficiency and extend the service life of the battery.     In summary, the endurance of solar street lights is affected by several factors, including the photoelectric conversion efficiency of solar panels, the energy storage capacity of batteries, and the stability of charging systems. Through scientific and reasonable design and material selection, solar street lights can achieve long-term continuous illumination, providing safe, energy-saving and environmentally friendly lighting services for our city at night.

   As an important part of urban lighting, AC LED street lights have many advantages. The following is a specific summary of the advantages of city street lamps:      Stable and reliable power supply: The AC LED street lights are directly connected to the city power grid, and the power supply is stable. Whether it is sunny, cloudy or rainy, they can provide lighting services continuously and stably to ensure the normal operation of street lamps.
