one major Municipal lighting 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 Municipal lighting The use of crystal oscillator time control can make the time control more accurate.

There are many types of LED street lights, which can be classified according to the following categories. 1 major Municipal lighting Height of street lights: high pole street lights, medium pole lights, street lights, garden lights, lawn lights; 2, according to major Municipal lighting Material of lamp pole: hot-dip galvanized railway lamp, steel street lamp and stainless steel street lamp; 3. Divided by shape: Chinese lamp, antique lamp, landscape lamp, single arm street lamp, double arm street lamp. 4. According to the power supply mode: urban circuit light, solar street light, wind solar complementary street light.

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 Municipal lighting 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 Municipal lighting , high ceiling lamps and other indoor and engineering lighting products and other technical advantages.

First, we need to observe major Municipal lighting 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 Municipal lighting 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.

Using the integrated technology of LED electro-optic source, according to major Municipal lighting The characteristics of semiconductor luminescence, ingenious circuit design and unique lighting geometric appearance, major Municipal lighting It can save more than 80% of electricity, realizing effective energy saving. The ultra long service life is up to 50000 hours, which can be used well in various special environments (such as low temperature and high temperature conditions). It solves the problems of low power and insufficient brightness of semiconductor electric light source in the lighting field, and shows excellent high brightness characteristics. There is no need for ballast, no starting difficulty, complete overcurrent, overvoltage, short circuit, temperature, surge protection, and its lighting optical performance is brighter and more complete than 75W/400W/1000W metal halide lamp.
