Solar led street lights do not need transmission lines, do not consume grid power, and can be used once and for all to make use of the inexhaustible wind and solar energy to provide stable and reliable lighting. Economic benefits.
1. Energy saving: providing energy by solar photovoltaic conversion, inexhaustible and inexhaustible;
2. Environmental protection: no pollution, no noise, no radiation;
3. Safety: The solar street light system has low voltage and there is no accident such as electric shock or fire;
4. Convenience: The installation is simple, there is no need to wire or “open the belly” to dig the ground construction, and there is no power outage and power limitation;
5. Long service life: The product has high technology content, and the control system and accessories are international brands, intelligent design, and reliable quality;
6. High grade: technology products, green energy, the use of units attaches importance to science and technology, green image improvement, grade upgrade;
7. Less investment: one-time investment and AC equivalent (alternative power investment from substation, power, control box, cable, engineering), one investment, long-term use;
8. Wide application: Solar energy comes from nature, so all places with sunshine can be used, especially suitable for green landscape lighting, high-end residential and outdoor lighting, tourist attractions, coastal landscape lighting and embellishments, industrial development zones, industrial and mining enterprises street lamps , outdoor lighting in major universities.
LED street light advantage
1, the characteristics of the LED street lamp itself - the unidirectional nature of light, no light diffusion, to ensure light efficiency;
2, LED street light has a unique secondary optical design, the light of the LED street light is irradiated to the area of the required illumination, further improving the light efficiency to achieve energy saving purposes;
3, LED light source efficiency has reached 110lm / W, and there is still a lot of room for development, the theoretical value of 250lm / W. The luminous efficiency of the high-pressure sodium lamp also reaches 100LM/W, but the light utilization rate of the lamp is only 60%. Therefore, the overall luminous efficacy LED street lamp is stronger than the high-pressure sodium lamp.
4. The color rendering of LED street lamps is much higher than that of high-pressure sodium lamps. The color rendering index of high-pressure sodium lamps is only about 23, while the color rendering index of LED street lamps reaches 75 or more. From the perspective of visual psychology, the same brightness is achieved, and the illumination of LED street lamps can be averaged. More than 20% lower than high pressure sodium lamps (refer to British road lighting standards);
5, LED street light's light decay is small, the light decay of less than 3% in one year, still meets the road use illumination requirement after 10 years of use, and the high-pressure sodium light decays, which has dropped by more than 30% in a year or so. Therefore, the LED street light is The power used can be designed to be lower than the high pressure sodium lamp;
6. LED street light has automatic control energy-saving device, which can achieve the maximum possible power reduction and energy saving when meeting the lighting requirements of different time periods.
7, LED is a low-voltage device, driving a single LED voltage is a safe voltage, the series of single LED power is 1 watt, so it is a safer than the use of high-voltage power supply, especially suitable for public places (for example: street lights Lighting, factory lighting, automotive lighting, civil lighting, etc.)
8, long life: can use more than 50,000 hours.
9, high light efficiency: the use of chips above ≥ 100LM, compared to the traditional high-pressure sodium lamp can save more than 60%.
10, easy to install: no need to add cables without rectifiers.
11, excellent heat dissipation control: summer temperature control at about 60 degrees, and passive cooling.
12, reliable quality: circuit power supply all use high-quality components, LED has over-current protection, no need to worry about damage.
13. Uniform light color: Sacrifice uniform light color without increasing brightness, thus ensuring no aperture.
Based on the above principle, the energy saving effect of the LED street lamp is remarkable, and the high-pressure sodium lamp can save more than 60% of electricity.
Low maintenance cost: Compared with traditional street lamps, the maintenance cost of LED street lamps is extremely low. After comparison, the total input cost can be recovered in less than 5 years.
