1、 Disconnection. For "dead light", we should first determine major Municipal lighting 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 Municipal lighting There are many reasons for dead lights. Dead light may appear in every link from packaging, application to use.
The solar street lamp is composed of six main components: solar panel, lithium battery, controller, LED lamp holder, lamp pole and ground cage; major Municipal lighting It is made of LED lamp holder. It consists of three parts: lamp pole and grounding cage. Since the solar street lamp uses unique solar panel, lithium battery and controller components, it can easily get rid of the tedious wiring process in the building, complete the charging process independently, and automatically turn on and off the sunshine time according to the lighting conditions, or even automatically adjust the brightness of the street lamp according to the brightness in the daytime; However, urban circuit lights cannot get rid of the independent existence of municipal electricity. Cables need to be embedded at an early stage to ensure the subsequent installation of street lights. In order to control the lighting time, major Municipal lighting Power distribution can only be carried out on the mains. Time control can be installed on the box, and the brightness control of lighting can only be completed by adding corresponding only equipment.
1. High purity aluminum reflector, accurate beam and good reflection effect. 2. Symmetrical narrow angle, wide angle and asymmetric light distribution system. 3. The rear open bulb can be replaced, which is easy to maintain. 4. The lamp is equipped with a dial to adjust the lighting angle. major Municipal lighting Controlled by the built-in microchip. In small engineering applications, it can be used without a controller, and can achieve gradual change, jump, color flicker, random flicker. DMX can also control dynamic effects such as gradients to achieve effects such as chasing and scanning. Its main application places may be: single building, exterior wall lighting of historical buildings, interior and exterior lighting of buildings, interior local lighting, green landscape lighting, billboard lighting, medical culture and other professional facilities lighting, bars, dance halls and other entertainment places major Municipal lighting 。
major Municipal lighting Corresponding rules and regulations shall be formulated for construction, and construction personnel shall strictly abide by the rules and regulations. Follow the instructions of the on-site construction personnel and complete the production tasks together. Expressway safety slogans, warning signs, etc. shall be set around the buildings, and shall not be removed or moved at will. Their movement shall be approved by the on-site construction director. The installation height of lamps shall be consistent. Install according to the design requirements. major Municipal lighting The height of should be equal to the width of the road to be lit. Bench drills, toothless saws, cutting machines, etc., as well as electric tools for processing, need to be equipped with leakage protection devices. The elevation angle of the lamp is determined by the street width and light distribution curve of the lamp, and the elevation angle of each lamp needs to be the same. The place where resin glue and paint are stored shall be far away from fire sources, and sufficient fire-fighting equipment shall be placed.
Like the hump of a camel, the battery of a solar street lamp has the function of storing energy. The importance is self-evident. Third generation solar street lamp battery replacement, from lead-acid battery to gel battery to lithium battery. At present, the mainstream major Municipal lighting Battery has gradually developed from gel battery to lithium battery. Relatively speaking, colloidal battery has low price, relatively mature technology and high stability. advantage. The disadvantages are that compared with lithium batteries of the same level, the service life is relatively short, the electric energy storage capacity of the same volume is less, and there are other fatal disadvantages. Although the apparent price is a little expensive, the use cost is very low. Two years of poor use, we major Municipal lighting engineering The battery pack can be used for 8-10 years. Welcome new and old customers to call and write.
The power supply of LED project lights is high-voltage alternating current. During installation, please keep away from the place that is easy to access, and properly ground the lamps to avoid electric shock accidents. When wiring, the installation personnel shall select the appropriate power line according to the power of the bulb actually used, and separate the power supply to avoid affecting the normal use of flood lights. major Municipal lighting It is designed to be waterproof and moisture-proof, and its protection grade can reach IP65. It can withstand the test of rain, but cannot work underwater, and its protection level cannot meet the requirements of underwater work. major Municipal lighting The installation position of shall be able to bear the weight of the projection lamp, and its bearing capacity shall be 10 times greater than the weight of the projection lamp, so that the lamp can be firmly installed and the danger of falling in the future can be avoided.
