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, Shijiazhuang major City circuit lamp 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， Shijiazhuang major City circuit lamp 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.

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 City circuit lamp 。 2. Energy conservation and environmental protection. Shijiazhuang major City circuit 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.

Computer modeling is used to simulate the luminous angle of the reflector light source and the spatial structure of the LED reflector, track the refraction track of light, and adjust the curvature of the reflector to achieve the light intensity distribution of the reflector The functional requirements of the LED light beam angle are greatly improved major City circuit lamp The light efficiency of the reflector reduces the possibility of astigmatism and glare. The reflective surface can be plated with orange peel and smooth. It can be more uniform and soft, without black holes, yellow circles. High reflection efficiency, no layering, high temperature resistance. The frosted mirror gently reflects light, which is suitable for occasions with weak light such as supermarkets and shopping centers. major City circuit lamp It is not applicable to places with high illumination requirements such as industries and stadiums. If it is used for industrial lighting, it needs a reflector with high refraction and luminous efficiency, and when the light passes through the reflector, it must reduce the light loss.

1、 Disconnection. For "dead light", we should first determine major City circuit lamp Is it short circuit or open circuit. 2、 The adhesive layer is peeled off. For some LED energy-saving project lights with vertical chips, the common reasons for dead lights are the peeling off of the bottom of the chip bonding layer and the peeling off of the bracket coating. 3、 The welding spot is burnt. In some cases, the dead light of the bulb may not be caused by the bulb itself, but also by the power supply used. 4、 Chip corrosion. The previous energy-saving floodlights and energy-saving floodlights are open circuit. The following is the condition of short circuit dead light. major City circuit lamp There are many reasons for dead lights. Dead light may appear in every link from packaging, application to use.

(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.
