Comparison of LED garden lights and traditional street lights (high pressure sodium lights)
With the widespread use of high-power LEDs in lighting decoration and lighting, power-type LED drivers are becoming more and more important. It will be possible to use high-power LED lighting for road lighting. Road lighting is the lamp with the longest use time and the most power consumption. The use of LED lamps in street lamps will greatly reduce the shortage of electricity in cities and save national energy. There are many domestic manufacturers of LED street lights, and the performance of their products varies greatly. Here only take the LED street lamp produced by our company as an example. Compare with the traditional street lamp (high pressure sodium lamp).
Below we will comment on the performance and economy of LED street lamps and traditional street lamps.
- Comparison of start-up performance LED street lights start instantly, and it takes more than 10 minutes for the high-pressure sodium lamp to start to reach normal brightness. During this time, the high-pressure sodium lamp consumes a lot of power, while the LED street light consumes normal power. Through the control circuit (such as Hangzhou Zhonggang Digital), the input voltage of the LED street light can be between 90 volts and 265 volts, which has no effect on the LED lights. The high-pressure sodium lamp cannot start when the input voltage is less than 185V, and the power increases by 12% when the input voltage exceeds 245V. In this way, high-pressure sodium lamps have higher requirements for power supply lines. The LED has no effect.
- Comparison of color rendering The color rendering of high-pressure sodium lamps can only reach 20 to 30, while LED street lamps can reach more than 85. Compared with traditional lamp lighting, the driver can better identify obstacles in the road and the surrounding environment of the road, and reduce the occurrence of traffic accidents. The level of color rendering directly reflects the scotopic difference (S/P) of human eyes to light. Therefore, the luminous flux emitted by the high pressure sodium lamp must be multiplied by a correction value (0.64) to be the light perceived by the human eye. strength. The luminous flux emitted by the LED lamp must be multiplied by a correction value (1.60) to be the intensity perceived by the human eye.
- Color temperature range The color temperature range of high-pressure sodium lamps is 2000 to 2500, while the color temperature range of LED street lamps is 2700k to 9000k. If the color temperature is low, it gives people a warm feeling in winter, but it gives people a hot feeling in summer. If the color temperature is high, it will give people a cold feeling in winter and a cool feeling in summer. Generally, people spend more time in the evening in summer, but less time in the evening in winter, and there are more hot weather than cold weather in the year. Therefore, it is better to use white light with a high color temperature for road lighting.
- Luminous decay The luminous decay of LED street lamps has a lot to do with the radiators of LED lamps. Some manufacturers do better. For example, our company adopts the self-developed "Multi-Layered Heat Dissipation System" technology that has obtained national invention patents. It is independently developed and opened, and the developed radiator makes it fit well with the lamp piece to achieve the best heat dissipation effect. According to the current data, its light decay is less than 3% in 10,000 hours! The light decay of the high pressure sodium lamp is generally greater than 25% in 2000 hours.
- Comparison of lamp efficiency The power efficiency of our company's LED street lamps can reach 88%, while the efficiency of high-pressure sodium lamps can only reach 70%. For example, the power consumption of a 120-watt LED street lamp is 138 watts, while that of a 120-watt high-pressure sodium lamp is 156 watts.
- Comparison of environmental protection LED street lights contain no mercury, no ultraviolet radiation, and low working temperature effectively reduce heat emissions. Because they save electricity, they save coal for power generation and use less coal for power generation, thus saving carbon dioxide emissions! The high-pressure sodium lamp contains mercury and ultraviolet radiation, and it emits a lot of heat during work, consumes electricity, wastes coal and emits a lot of carbon dioxide! The LED power factor is greater than 0.99, and the power factor of the high-pressure sodium lamp is about 0.44. In this way, the pollution of the LED to the power grid is small, and the pollution of the high-pressure sodium lamp to the power grid is great! LED lamps have no stroboscopic and light pollution, while high-pressure sodium lamps have obvious stroboscopic and light pollution.
- Effective light utilization rate Due to the characteristics of LED light source similar to point light source, it emits directional light to the illuminated object. There is basically no waste of light, so it has a very high light utilization rate, which can reach more than 92%. However, because the high pressure sodium lamp emits on all sides, part of the light is blocked by the light source itself and has a large luminous point. It is difficult to make optical design, and the efficiency of the lamp is not high, and the output The light spot will not reconcile with the required effective irradiation surface and waste part of the light source. Therefore, it is projected to the surface of the illuminated object through the reflector of the lamp, and part of the light will be lost in the middle. Therefore, the effective light utilization rate of traditional lamps is 55~60%
Source and development:
Road lighting is an important part of urban lighting. Traditional street lamps are often used. High-pressure sodium lamps emit 360 degrees, and the shortcomings of large light loss have caused a huge waste of energy. At present, the global environment is deteriorating day by day, and all countries are developing clean energy. With the rapid growth of the national economy, the contradiction between my country's energy supply and demand has become increasingly prominent, and there has been a serious shortage of power supply. Energy conservation is an urgent problem to be solved. Therefore, the development of a new type of high-efficiency, energy-saving, long-life, high color rendering index, environmentally friendly LED street lamps is of great significance to the energy saving of urban lighting.
Road lighting is closely related to people’s production and life. With the acceleration of my country’s urbanization process, LED street lights have gradually adopted advantages such as directional lighting, low power consumption, good driving characteristics, fast response speed, high earthquake resistance, long service life, and environmental protection. Into people’s vision, it has become the world's most energy-saving light source of a new generation with the advantage of replacing traditional light sources. Therefore, LED street lights will become the best choice for road lighting energy-saving transformation.
LED street lights refer to street lights made with LED light sources, which have the unique advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response speed, and high color rendering index. They are of great significance to energy saving in urban lighting.
The difference between LED street lights and conventional street lights is that the LED light source adopts low-voltage DC power supply and is a high-efficiency white light synthesized by GaN-based power blue LED and yellow. It has high efficiency, safety, energy saving, environmental protection, long life, fast response speed, high color rendering index, etc. Unique advantages, can be widely used on roads. The outer cover can be made, the high temperature resistance can reach 135 degrees, and the low temperature resistance can reach -45 degrees.
- Its own characteristics-one-way light, no light diffusion, ensuring light efficiency.
- The LED street lamp has a unique secondary optical design, which irradiates the light of the LED street lamp to the area that needs to be illuminated, and further improves the light efficiency to achieve the purpose of energy saving.
- The LED has reached 110-130lm/W, and there is still a lot of room for development, the theoretical value reaches 360lm/W. The luminous efficiency of high-pressure sodium lamps increases with the increase of power. Therefore, the overall luminous efficiency of LED street lamps is stronger than that of high-pressure sodium lamps; (The overall luminous efficiency is theoretical, in fact, the luminous efficiency of high-pressure sodium lamps above 250W is higher than that of LED lamps. ).
- The light 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 is above 75. From the perspective of visual psychology, the same brightness can be achieved. It is more than 20% lower than high pressure sodium lamp.
- The light decay is small, the light decay in a year is less than 3%, and it still meets the road requirements after 10 years of use, while the high-pressure sodium lamp has a large decay, which has dropped by more than 30% in about a year. Therefore, the design of the power of the LED street lamp Can be lower than high-pressure sodium lamps.
- The LED street lamp has an automatic control energy-saving device, which can achieve the greatest possible reduction in power and energy saving under the condition of meeting the lighting requirements at different times. It can realize computer dimming, time period control, light control, temperature control, automatic inspection and other humanized functions.
- Long life: It can be used for more than 50,000 hours and provides three-year quality assurance. The disadvantage is that the life of the power supply cannot be guaranteed.
- High light efficiency: Using chips ≥100LM, it can save more than 75% energy compared with traditional high pressure sodium lamps.
- Easy installation: no need to add buried cables, no rectifiers, etc., directly connect to the lamp pole or nest the light source into the original lamp housing.
- Excellent heat dissipation control: the temperature in summer is controlled below 45 degrees, and passive heat dissipation is adopted, and the heat dissipation in summer is insufficient.
- Reliable quality: All circuit power supplies use high-quality components, and each LED has individual overcurrent protection, so there is no need to worry about damage.
- Uniform light color: No lens is added, and uniform light color is not sacrificed to improve brightness, so as to ensure uniform light color without aperture.
- The LED does not contain harmful metal mercury and will not cause harm to the environment when it is scrapped.
Combining the above principles, the energy-saving effect is remarkable, and it can save more than 60% of electricity instead of high-pressure sodium lamps.
Low maintenance cost: Compared with traditional street lamps, the maintenance cost of LED street lamps is extremely low. After comparison, all input costs can be recovered in less than 6 years.
- A single LED has low power. In order to obtain high power, multiple parallel connections are required.
- Low color rendering. The color displayed under LED illumination is not as true as that of an incandescent lamp. This must be analyzed from the spectral distribution, which is a technical problem.
- Light spot. Due to the defects in the manufacturing process of the white LED itself and the matching error with the reflecting cup or lens, it is easy to cause the "yellow circle" problem.
- LED illumination uniformity problem. If the secondary optical design is not carried out, the illumination of the LED is relatively concentrated, so the secondary optical design must be carried out to make the light intensity distribution chart look like a bat.
- The light decay of LED. Compared with low-power LEDs, high-power LED street lights have much better light decay. However, low-power LEDs emit very little heat. The high-power LED has a problem that cannot be solved by heat dissipation, and the brightness will be significantly reduced after heating, so the power cannot be increased. The largest Spark LED street light sold in the market is 360W.
Technology is becoming more and more mature, and high-power LED light sources can already meet the needs of general street lights. The luminous efficiency of the general high-pressure sodium lamp is 100LM/W, and the commonly used high-power LED is 50-60LM/W. It can reach 80LM/W with foreign LED chips. The higher the luminous efficiency, the better the energy-saving effect. This is also the choice One of the most important indicators of LED street lights. However, there is no clear stipulation in the LED standard, so you must carefully confirm when purchasing LED street lights.
And some businesses, in order to reduce costs, use hundreds of low-power LEDs of 0.5W. However, the light decay of this low-power LED is very serious, and its light decay to 80% has a life span of only 1000 hours. Therefore, as a street lamp that needs to be used for a long time, it is absolutely not allowed to use such low-power LEDs. Using high-power LEDs (generally more than 30W) will have a much better light decay.
Due to the high technical content and complex composition of LED street lamps, the weight of some high-power lamp holders will far exceed that of ordinary high-pressure sodium lamps, so the requirements for corresponding supporting materials are higher. However, some LED street lamp manufacturers have tried their best to reduce the self-weight of the LED lamp holder, from about 30 kg per lamp holder to more than 10 kg, and the weight reduction has a further downward trend.
Because LED is a semiconductor component, when its chip is affected by temperature and reduces to 30% of the initial luminous flux, it will lose its illumination meaning, that is, the end of life. In theory, the life of high-power LED street lights is 30,000 to 50,000 hours, but The important premise is good heat dissipation. It is worth mentioning that domestic manufacturers have adopted the world's leading needle-shaped heat dissipation technology.
The technology is becoming more and more mature, and the efficiency of the light source has reached more than 100lm/W, which makes the energy-saving transformation of urban street lighting possible. LED street lamps, especially high-power LED street lamps, are impacting the traditional street lamp market at a rapid pace.
As the name implies, high-power LED street lights are street lights with a power greater than 30 watts and using a new type of LED semiconductor light source. The standard is generally the uniformity of road illuminance, in line with road illuminance. (The actual 1/2 center spot reaches 25LUX, the 1/4 center light intensity reaches 15LUX, the lowest light intensity at 16 meters is 4LUX, and the overlap light intensity is about 6LUX. It refers to the LED street light that uses solar silicon panels as the power supply.

- The average illuminance of uniformity of road surface illuminance is 0.48, and the spot ratio is 1:2.
- Meet the road illuminance. (The actual 1/2 center spot reaches 25LUX, the 1/4 center light intensity reaches 15LUX, the lowest light intensity at 16 meters away is 4LUX, and the overlapping light intensity is about 6LUX.
- It has very good application prospects in new urban lighting. Dimming depth, and color and other characteristics will not change due to dimming.
- Adapt to humidity: ≤95.
Despite the rapid development of LED street lights, the standard of LED street lights is relatively lagging behind. Globally, there are not all LED street lamp standards, such as European standards for LED street lamps. In fact, the standards for LED street lamps in various regions are not the same in terms of indicators. LED street lamps must meet the requirements of the sales area in terms of standards. Therefore, bidding for LED street lamp projects requires in-depth study of local LED street lamp standards. Only in this way will it be fierce. Occupy a place in the market competition.
MIC A street light is characterized by simplicity, ease of use, light weight, and strong integration. The characteristics of our lamp determine its low price and low freight cost. The greatest benefit to customers.
