With the rapid development of road traffic, the scale and quantity of street lighting facilities are also increasing, and the power consumption of street lighting is rising rapidly. Energy saving for street lighting has become a topic that has received increasing attention. Today, LED street light manufacturer Tianxiang will take you to learn about energy-saving measures for street lighting.
1. Promote green lighting sources
Green lighting is energy-efficient, environmentally friendly, safe, and comfortable. It consumes less electricity to obtain sufficient lighting, thereby significantly reducing the emission of air pollutants and achieving the purpose of environmental protection. The light is clear and soft, does not produce harmful light such as ultraviolet rays and glare, and does not produce light pollution.
2. Hierarchical control
According to the technical requirements of urban lighting, graded control can be carried out according to the color function and brightness requirements. For low-illumination areas including green land and residential areas, it is best to control the brightness within the range of 5-13cd/. For medium-illuminance areas including medical institutions, it is best to control the brightness within the range of 15-25ed/, and for high-illuminance areas including traffic areas, it is best to control the brightness within the range of 27-41ed/ .
3. Reduce road brightness and illumination level in the middle of the night
If there are many vehicles on the same road in the middle of the night and the requirements for contrast are high, but in the middle of the night, the number of vehicles decreases and the requirements for contrast levels are lowered. At this time, some measures can be taken to reduce the illumination of the road surface, so as to achieve the purpose of energy saving. The easiest way is to turn off some street lights at intervals in the middle of the night to reduce the illumination of the road surface. The advantage of this method is that it is simple, practical and low in cost. The disadvantage is that the uniformity of illumination is greatly reduced and cannot meet the requirements of lighting standards. Therefore, it is generally not recommended for large and medium-sized cities. This method, and another method is better than this method of turning off part of the lamps. It is to use dual light source lamps and turn off one light source in the same lamp late at night. The advantage of this method is that the uniformity remains unchanged and the management is simple. convenient.
4. Strengthen the maintenance and management of street lighting facilities
After the street lamp is put into use, due to the long-term exposure to the sun and rain and the accumulation of dust inside and outside the protective cover, the light transmittance of the lamp will decrease, the luminous flux will decrease, and the energy saving efficiency will decrease. Therefore, it should be checked and wiped regularly according to the actual situation. At the same time, it is also possible to improve the luminous flux utilization rate of the light source by wiping the lamps. In this way, it is possible to achieve the purpose of energy saving by selecting a light source with a lower power under the premise of meeting the lighting quantity and quality requirements.
5. Choose high-efficiency and energy-saving lighting systems
The use of high-efficiency energy-saving light sources can greatly reduce energy consumption, and long-life energy-saving lighting products will also reduce future maintenance and replacement costs, reduce maintenance manpower, and thus save costs for enterprises.
6. Formulate scientific control of street light switching time
When designing street light switches, there should be manual control, light control and time control. Different street light switch times can be set according to the characteristics of different roads. The power of the light bulb can be automatically reduced in the middle of the night to reduce the power consumed by the light bulb. Turn off half of the street lights through the all-night and midnight double contactor control in the street light distribution box, effectively reducing power waste and saving energy.
