At present, there are basically two kinds of sensors used for parking lot lighting. One is infrared sensor, which is relatively cheap. However, due to the height of the floor, the limitation of the metal tube and the influence of the radiation angle, the infrared sensor has a certain detection blind spot. The other is a microwave sensor, which can overcome the disadvantage of detecting corner blind areas, but the price is higher. These two sensors and major Smart street lamp Combined, the lighting energy saving of the underground parking lot is effectively realized. When someone moves the car under the light, major Smart street lamp It will run at full speed to meet the lighting demand. When there is no car and no car, the lamp is in a sleep state, and low power lighting of about 3W is maintained to maintain the required safety lighting. Low illumination, realizing energy saving of lighting.

1. Strong anti-static capability: LED with strong anti-static capability has a long service life. 2. Brightness: The price of LED varies with its brightness. 3. Wavelength: LEDs with the same wavelength and color are expensive. 4. Luminescence viewpoint: LEDs for different purposes have different luminescence viewpoints. 5. LED chip: major Smart street lamp The illuminant of is a chip, and the price of different chips varies greatly. 7. Colloid: Generally, the colloid of LED is epoxy resin. LEDs with UV resistance and flame retardancy are more expensive. 8. Chip size: the chip size is represented by the side length. Big chip major Smart street lamp Its quality is better than that of small chips. The price is proportional to the chip size. 9. Radiator: The radiator can see the appearance of the lamp. Temperature will affect the life of LED lamp beads. Counting plays a vital role. 10. Power supply: According to the plan requirements of different manufacturers, it can be divided into two types: constant current power supply and constant voltage power supply.

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 Smart street lamp 。 2. Energy conservation and environmental protection. Zhaoqing major Smart street 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.

LED garden lights are energy-saving and environmentally friendly. The main structure is an electroluminescent semiconductor diode, which has low luminous flux loss and long service life. According to the scientific research results of LED light source, major Smart street lamp Its service life is three times that of the basic light source and 30% that of the energy-saving street lamp. Power saving is equal to saving the investment in electricity costs, and it is also because LED courtyard lamps have their unique advantages, which can meet the requirements of today's society for energy conservation and environmental protection. courtyard major Smart street lamp The advantage of saving more electricity costs has a wide influence on the market. In order to improve people's quality of life, the street lamps that need to be used are energy-saving and environmentally friendly. Both specifications, lighting performance and lighting effect can meet the requirements of street lamp standards. Facing many LED garden lights with complex market environment, it is necessary to choose a good brand LED garden light manufacturer.

Using the integrated technology of LED electro-optic source, according to major Smart street lamp The characteristics of semiconductor luminescence, ingenious circuit design and unique lighting geometric appearance, major Smart street lamp 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.
