Solar Road Studs is an important part of urban lighting. Traditional
Road Studs often use high-pressure sodium lamps. The low overall light efficiency of high-pressure sodium lamps results in a huge waste of energy. Therefore, the development of new high-efficiency, energy-saving, long-life, color rendering index High and environmentally friendly street lamps are of great significance to urban lighting energy conservation. Here are some of the advantages of
LED Solar Road Studs introduced by Ruichen:
The difference between high-power
LED Solar Road Studs and conventional high-pressure sodium lamp street lamps is that the light source of high-power
LED Solar Road Studs adopts low-voltage DC power supply, high-efficiency white light diodes synthesized by GaN-based power blue LEDs and yellow phosphors. Diode, abbreviated as LED) is a high-efficiency solid-state light source based on a semiconductor PN junction that can emit light with weak electrical energy. Under a certain forward bias voltage and injection current, holes are injected into the P region and electrons are injected into the N region. After diffusing into the active region, it is radiatively recombined to emit photons, which directly convert electrical energy into light energy.
As the light source of
Solar Road Studs, LED has many advantages compared with traditional Road Studs light source.
1. The LED Solar Road Studs itself has the directivity of light, without the diffusion of light, to ensure the light effect;
2. The
LED Road Studs has a unique secondary optical design, which irradiates the light of the LED
Road Studs to the area that needs to be illuminated, that is, the road surface, which further improves the lighting efficiency and achieves the purpose of energy saving;
3. The light source efficiency of LED Road Studs has now reached 100lm/W, and there is still a lot of room for development. The theoretical value can reach 250lm/W. The luminous efficiency of high-pressure sodium lamps increases with the increase of power. Therefore, the overall Light effect LED
Solar Road Studs is stronger than high pressure sodium lamps;
4. The light color rendering of LED Solar Road Studs is 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
Solar Road Studs can reach more than 75. From the perspective of visual psychology, to achieve the same brightness, LED Solar The illuminance of Road Studs can be reduced by more than 20% on average than high pressure sodium lamps (refer to the British road lighting standard); and, at the level of intermediate vision, the human eye is more likely to distinguish things in a high color temperature environment than a low color temperature environment, avoiding certain dangers the occurrence of the state;
5. The light decay of LED
Solar Road Studs is small, the light decay in one year is less than 3%, and the illuminance requirements for road use are still met after 10 years of use. Therefore, the power design of LED Solar Road Studs can be lower than that of high pressure sodium lamps;
6. LED Solar Road Studs can be automatically dimmed, which can meet the lighting requirements at different time periods, reduce power to the greatest extent possible, and save electricity;
7. LED is a low-voltage DC device, and the voltage driving a single LED is a safe voltage, so it is a safer power supply than using a high-voltage power supply, especially suitable for public places. The characteristics of DC make LED especially suitable for combining with solar energy and wind power;
8. Each unit LED die has only a small volume, so it can be prepared into various shapes of devices, and is suitable for variable and shock-prone environments;
9. Long life of
Solar Road Studs: the theoretical life can be used for more than 50,000 hours;
10. LED Solar Road Studs can be switched frequently without worrying about its damage;
11. Easy installation: directly install the
LED Solar Road Studs lamp head on the lamp pole to replace the original sodium lamp head.
