Things to Pay Attention to for High-Power LED Street Lights
High-power LED street lamps are the best choice to replace traditional street lamps such as high-pressure sodium lamps and ordinary energy-saving street lamps, and in recent years, high-power LED street lamps have been widely used because of their advantages of environmental protection, energy saving and long life.
High-power LED street lamps have also been built in the process of application development, although the current high-power LED street lamp technology of LED street lamp manufacturers has been discussed, there are not too many quality problems, but we also have some when buying high-power LED street lights
The following problems can be solved:
1. The bottleneck of high-power LED street lamps is heat dissipation, and it is necessary to pay attention to whether the heat dissipation performance of the street lamp is good when purchasing, because this directly affects the service life of the street lamp.
2. The power supply is also one of the most critical factors affecting the service life of the street lamp, and it is necessary to pay attention to the power quality of the high-power LD street lamp, such as the power supply efficiency, how to design the circuit, and whether the power supply has overcurrent, overtemperature, overvoltage, surge, heavy blow and other protection.
High-power LED street lamps should also pay attention to their light distribution curve, light flow, lighting efficiency, stability performance, etc.
How to Choose the Wattage of High Power Led Street Light?
1. LED street light testing area
The test road is 15 meters wide, the street lamp is 10 meters high, the lamp arm is 1 meter at an elevation angle of 10 degrees, and the street lamp is tested on one side; the test area is 15mx30m , considering that the narrower road has low requirements for the lateral light distribution of the street lamp, and provides applications at the same time The data of the area of 12mx30m is for reference and selection of roads of different widths.
2. LED street light test data
The data is the average of three times, and the light decay is calculated according to the results of the first and third times. The time span is 100 days and the lights are normally turned on and off every day.
3. Evaluation of luminous flux, luminous efficiency and illuminance uniformity of LED street lamps
The calculation formula of luminous efficiency is luminous flux divided by input power;
The calculation formula of luminous flux is the average illuminance x area;
The illuminance uniformity is the ratio of the minimum illuminance and the maximum illuminance of the measuring points in the lateral direction of the road.
In the application of street light engineering, how many wattage street lights should be installed on the road should be combined with the actual street light effect. On the same road, the 100W LED street lamps provided by manufacturer A can meet the lighting requirements, while the street lamps provided by manufacturer B may only need 80W or even lower wattage to meet the lighting requirements.
Street lights are important road lighting fixtures. In street light engineering, it is more important to choose a reliable LED street light manufacturer. As a LED street light manufacturer in China, Huapu Yongming obviously pays more attention to the quality and effect of street lights than middlemen.
How to Choose a High Power Led Street Light
Wattage
High power led street light use fewer watts for the same amount of illumination as the traditional high-pressure sodium lamps. For instance, a 100w high-pressure sodium lamp is equivalent to a 36w led lamp. An led lamp of 60w is equivalent to a 150w high-pressure sodium lamp. The commonly used led wattages are 5w, 10w, 15w, 20w, 30w, 40w, 50w, 60w, 80w, 100w, and 120w. Note that 60w or less are commonly used for led ordinary lighting while 60w or more are used for lens or mirror. The height of the pole also influences the wattage of the led street lamp to purchase. For instance, 10w led street lamps are suitable for poles with a height of between 2.5 to 3 meters. 100w and 120w are best suited for poles with heights above 10 to 12 meters. The number of lanes is another factor to consider regarding the wattage of led lamps.
Led driver
Led drivers are critical to high power led street light, they do the heavy lifting of converting ac to dc at a stable rate. Only led drivers with large resistors will last the 10-20+ years of the light. Also needed must be considered before choosing a suitable led driver. One good example is the kind of function you need for your led street light. Examples of these functions include output lumen compensation (olc), timing dimming, thermistor (ntc), d4i, dali, 0-10v, and auxiliary power supply. It is advisable to research more on these functions before choosing a led street light.
Led chips
Led chips majorly determine the quality of an led light. It includes the stability and brightness of led light. Both variables are vital for the performance of led street lights. Several led chips options are available in the market. The most common ones are 3030 and 5050. 3030 led chips are best known for their higher-cost performance. 5050 led chips, on the other hand, are a better option for an energy management contract.
Lens/optics
Led street lights offer a wide variety of optical light distributions. The various optical light distributions are suitable for roadways, architectural, and area lighting for better light uniformity. Fortunately, several manufacturers provide customized products to their customers with special light distribution requirements.
Correlated color temperature (cct)
This is a measurement used to illustrate the relative color appearance of the led illumination source. This measurement indicates whether a light source appears more white, yellow, or bluer. Cct is measured in kelvins. Examples are 5700k denoted as "cool", 4000k as "neutral", and 2700k as "warm."
Color rendering index (cri)
Cri is one of the essential aspects of lighting. In addition to denoting the quality of light, it also represents the ability of light to faithfully (near accurate) reproduce the color of objects. The higher the value of cri, the better. Despite 100 being the ideal cri, for an led street light, a cri of around 70 is sufficient.
Main Differences Between Regular Street Lights and High Power LED Street Lights
Cost
Ordinary street lights use high-pressure sodium lamps, while high-power led street lights are much less expensive to run. Leds require less power but produce more light while consuming less energy. This means that using led systems can save up to 75% on monthly utility bills compared to traditional lighting.
Maintenance
High-power led street lights require much lower maintenance than normal lighting systems. Leds require little to no cleaning and bulb replacement as frequently as possible, which is often cumbersome in traditional lighting systems. In addition, the long lifespan of leds means that you don't have to worry about expensive repairs or frequent bulb replacements.
Brightness
High-power led street lights provide more efficient lighting, better visibility, and brighter light. As a result, they are ideal for areas that require increased lighting, such as parking lots or parks. Leds are capable of producing a much higher lumen output than regular street lights, making it easier to see at night.
Environmental impact
High-power led street lights are more environmentally friendly than traditional lighting systems because they consume less energy. This means that they produce less heat, which reduces the amount of carbon emissions emitted into the atmosphere. In addition, leds emit colder light, which reduces the risk of wildlife being harmed by the high heat of general lighting systems.
Safe
Finally, high-power led street lights provide an extra layer of safety for pedestrians and drivers. The bright light emitted by leds helps reduce the risk of accidents by improving visibility in low-light areas. In addition, many high-power led street lights are equipped with built-in motion sensors or dimming functions to further enhance safety.
Precautions for Using High-Power LED Street Lights
The power supply must have a constant current
The material characteristics of the light source of high-power LED street lamps determine that they are affected by the environment, such as the increase of temperature and voltage, which will lead to the increase of the current of the LED, and if the rated current is exceeded for a long time, the service life of the LED lamp beads will be greatly shortened.
Power supply constant current accuracy
Some power supplies on the market have poor constant current accuracy, the error can reach ±8%, the constant current error is too large, and the general requirement is ± 3%, according to the 3% design scheme, the production power supply needs to be finely tuned to achieve an error of ±3%.
The operating voltage of the power supply
Generally, the recommended working voltage of LEDs is 3.0-3.5V, and after testing, most LEDs work at 3.2V, so the calculation formula of 3.2V is more reasonable. The total voltage of N lamp beads in series = 3.2*N.
The operating current of the power supply
For example, the rated working current of LED is 350 milliamperes, some factories have used all of them at the beginning, designed to be 350 milliamperes, but in reality, the heating of this current is very serious, after many comparative experiments, the design of 320 milliamperes is more ideal, minimize heating, and convert more electrical energy into visible light energy.
The power board is connected in series and parallel, with a wide voltage
To ensure that the high-power LED street lamp power supply works within the wide input voltage range of AC85-265V, the LED series and parallel connection mode of the lamp board is very important, try not to use a wide voltage, and try to divide AC220V and AC110V to ensure the reliability of power supply.
In addition, the number of series connections should not exceed 45, and the number of parallel connections should not be too much, otherwise the working current will be too large and the power supply will be seriously heated.
Isolated/non-isolated
Generally, if the 15W isolation power supply is placed in the high-power LED street lamp power tube, its transformer is very large, it is difficult to stuff it in, mainly depending on the specific situation of the space structure, and the isolation can only be 15W, very few more than 15W, the price is also very expensive, so the cost performance of isolation is not high, in fact, if the safety measures are in place, there is no problem.
Power efficiency
The input power minus the output power parameter is particularly important, the higher this value, the lower the efficiency, which means that a large part of the input power is converted into heat and dissipated; If it is installed inside the luminaire, it will generate a very high temperature, and when combined with the heat emitted by the light efficiency ratio of our LEDs, it will add up to produce a higher temperature. 9. Heat dissipation.
The main factor of the heat dissipation scheme is that the use of high-power LED street lamp beads in the case of non-overheating can greatly extend its life, while aluminum alloy is generally easier to dissipate heat, that is to say, the high-power LED street lamp power lamp beads are attached to the aluminum substrate to maximize the external heat dissipation area as much as possible.
