(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 Cast light 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 Cast light 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.

The ultraviolet ray of LED energy-saving lamps is not particularly strong. major Cast light It will not appear after using for a period of time. It may feel particularly strong and will not produce ultraviolet light, so it will not fade, will not be disturbed by mosquitoes, and the indoor sanitation can also become clean. major Cast light It can also protect our eyes well. When starting, the time is faster, so it will not flash, so it can protect the eyes. The main advantage is that it can save power and has a longer service life. This is a good and reasonable guarantee. When you use it, you don't have to worry about life problems or abnormalities, nor about the cost of replacing the bulb. Moreover, when you use it, it is relatively robust and does not worry about frequent use. This would be bad.

one major Cast 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 Cast light The use of crystal oscillator time control can make the time control more accurate.

First, we need to observe major Cast light The workmanship of the mask and its luminous effect. This depends on how much light the bulb lamp shade emits to the light source. When viewing the mask, you can view its shape, whether the light transmittance and thickness of the bulb are the same, and check the approximate blur of the mask. We need to see if the material of the bulb is suitable for heat conduction. You can test in the field. After working for several minutes, observe whether there is odor above the bulb when the temperature rises. After that, we will also check the lamp body temperature after the power is turned off. The lower the temperature, the better. ordinary major Cast light It will change due to the change of ambient temperature. When selecting bulb lamp, you need to check its color temperature. Generally speaking, the color temperature should not be too high or too low as long as it can meet the normal household lighting needs.

In order to better serve customers, the two companies will share the following technologies with each other. Shandong Qihang Electric Co., Ltd. will share the advantages of workshop, street lamp production technology, street lamp twelve phase, solar street lamp technology and street lamp cap technology. Shandong Lanyue Photoelectric Technology Co., Ltd major Cast light Six phase and other related technologies of flood lights, tunnel lights and other indoor and landscape lights. In order to safeguard the interests of customers, the two companies will communicate with each other in the market. Qihang Electric will share factory customers, while Lanyue Optoelectronics Co., Ltd. will share municipal users. After communication, Qihang Electric will use its own municipal street lights and solar street lights. Technical advantages such as intelligent lighting equipment provide outdoor lighting technical services for customers of Lanyue Optoelectronics, and Lanyue Optoelectronics provides outdoor lighting technical services for customers of Shandong Qihang Electric Co., Ltd major Cast light , high ceiling lamps and other indoor and engineering lighting products and other technical advantages.

1. Advocate the concept of environmental protection and recycling globally. Traditional lamps contain many harmful substances. If the bulb fails, harmful substances will volatilize into the atmosphere. But, Xiaogan major Cast light It does not contain harmful substances at all and can protect the environment. Shandong LED ceiling lamp is recognized as a green lighting product in the 21st century. 2. Shandong LED mining lamp saves energy, has a long service life and saves maintenance costs. The power consumption of LED industrial and mining lamps in Shandong Province is generally less than one third of that of traditional lamps, and their service life is 10 times that of traditional lamps. It can be used for a long time without replacement, thus reducing the labor cost. 3， Xiaogan major Cast light It can also protect eyesight. Traditional lamps use AC power, but Shandong LED industrial and mining lamps directly convert AC power to DC power without flickering, which can protect the eyes. 4. Shandong LED mining lamp has high efficiency and luminous efficiency.
