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.
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 Smart street 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 Smart street 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. 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.
The working voltage of a single bulb for LED tunnel lighting is very low, about 3V, so the power consumption of a low-voltage working environment is half of the power required for the same strong light. The tunnel lamp has a long service life and does not need regular maintenance and inspection. After a period of use, the traditional major Smart street lamp The brightness of the tunnel lamp will be greatly reduced, but its attenuation is only 20% of that of the tunnel lamp. Moreover, the tunnel lamp is small in size and can be made into various shapes to adapt to various environments. The shell of the tunnel lamp is of integrated design, which is durable and not easy to be damaged. Each light source inside can be installed and removed separately, which is very convenient in the future maintenance process, and the overall design can ensure good heat dissipation effect. The heat dissipation rack inside the shell, the airflow and the heat emitted by the full contact with the air, effectively reduce the major Smart street lamp And prolongs the service life of the tunnel lamp.
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 Smart street lamp 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 Smart street lamp 。
(1) Material requirements: an excellent energy-saving mining lamp is made of aluminum alloy with high thermal conductivity, and its surface is sprayed with anti-corrosion metal paint to ensure heat dissipation in the future. (2) Brightness requirements: according to different use environments major Smart street lamp There are high requirements for the brightness of. Generally, the power used in normal space and large shopping centers is mostly 50w-100w lumens above 3000, and the brightness of the lights is selected according to the size of the area. (3) Heat dissipation performance: the quality of LED energy-saving mining lamp radiator has a great impact on its quality. We produce major Smart street lamp The thickened and accurate automobile aluminum strong convection radiator is adopted, and the working mode is eddy current heat dissipation. The service life of the light source is largely guaranteed.
