Henan LED street light supply DLD07205

1. The characteristics of LED street lights in Henan - unidirectional light, no light diffusion, ensuring lighting efficiency.
2. Henan LED street lights have a unique secondary optical design that directs the light to the required illumination area, further improving lighting efficiency to achieve energy-saving goals.
3. The luminous efficacy of LEDs has reached 110-130lm/W, with significant room for development, theoretically reaching 360lm/W. In contrast, the luminous efficacy of high-pressure sodium lamps increases only with power, so overall, LED street lights are more efficient than high-pressure sodium lamps; (this overall luminous efficacy is theoretical; in practice, high-pressure sodium lamps above 250W may have higher efficacy than LEDs).
4. The color rendering of Henan LED street lights is much higher than that of high-pressure sodium lamps, which have a color rendering index of around 23, while LED street lights reach above 75. From a visual psychological perspective, to achieve the same brightness, the illuminance of LED street lights can be reduced by more than 20% compared to high-pressure sodium lamps.
5. Low light decay: less than 3% light decay in one year, still meeting road requirements after 10 years, while high-pressure sodium lamps have significant light decay, dropping by over 30% in about a year. Therefore, the power design for LED street lights can be lower than that of high-pressure sodium lamps.
6. Henan LED street lights have an automatic control energy-saving device that can maximize power reduction under different lighting requirements and save electricity. It can achieve computer dimming, time-based control, light control, temperature control, automatic inspection, and other user-friendly functions.
7. Long lifespan: can be used for over 50,000 hours and provides a three-year quality guarantee. The downside is that the lifespan of the power supply cannot be guaranteed.
8. High luminous efficacy: uses chips with ≥100LM, saving more than 75% compared to traditional high-pressure sodium lamps.
9. Easy installation: no need for buried cables or rectifiers; simply connect to the lamp pole or embed the light source into the existing lamp housing.
10. Excellent heat dissipation control: temperature controlled below 45 degrees in summer and uses passive heat dissipation methods; summer heat dissipation may be insufficient.
11. Reliable quality: all circuit power supplies use high-quality components, with each LED having individual overcurrent protection, eliminating concerns about damage.
12. Uniform light color: no lenses added and no sacrifice of uniform light color for increased brightness, ensuring uniform light color without halos.
13. LEDs do not contain harmful metals like mercury and will not harm the environment when disposed of.
The energy-saving effect based on the above principles is significant; replacing high-pressure sodium lamps can save over 60% electricity.
Low maintenance cost: compared to traditional street lights, LED street lights have extremely low maintenance costs; after comparison, all investment costs can be recovered in less than six years.

TECHNICAL PARAMETER

PRODUCT DESCRIPTION

LED street lights refer to street lights made using LED light sources and have unique advantages such as environmental friendliness, long lifespan, fast response speed, and high color rendering index; they are very important for energy saving in urban lighting.

Road lighting is an important component of urban lighting. Traditional street lights often use high-pressure sodium lamps that emit light in a full circle (360 degrees), leading to significant energy waste due to large light loss. Currently, the global environment is deteriorating day by day, and countries are developing clean energy sources. With the rapid growth of the national economy in China, the contradiction between energy supply and demand has become increasingly prominent; there is a serious shortage of electricity supply and energy saving is an urgent issue that needs to be addressed.

Therefore, developing new types of energy-saving LED street lights with long lifespans and high color rendering indices is very important for energy saving in urban lighting. Road lighting is closely related to people's production and life; as urbanization accelerates in China, LED street lights are gradually coming into people's view due to their advantages such as directional lighting, low power consumption, good driving characteristics, fast response speed, high seismic resistance, long lifespan, and environmental friendliness. Thus, LED street lights will become the choice for energy-saving transformation in road lighting.
