LED floodlights for street lighting: a safe life in bright light

LEDs are a new generation of lighting. In a relatively short period of time, they have gained wide popularity due to their high illumination rates with low energy costs. The advantages are provided by the design features and the principle of operation based on light-emitting diodes. To learn more about how they are arranged, where they are used and how to choose LED floodlights for street lighting, this article will help.

LED street floodlights: features and benefits

LED lamps are characterized by high quality, economical power consumption, reliability and long service life. It is the efficiency and durability that are the main features of LED floodlights, thanks to which they differ from conventional lamps.

Diode floodlights have a number of advantages, among which the following stand out:

• low level of electricity consumption;
• high illumination;
• safety for the environment;
• wide range of applications.

The main disadvantage of LED floodlights is their high cost, which has become the reason for limiting the widespread use of lamps in various fields. They still remain leaders in the list of the most expensive lighting methods. The high price of LED floodlights is due to the significant costs that are required for the manufacture of devices. At the same time, long lamp life and low power consumption guarantee a 100% return on investment.

The minimum service life of LED devices is 50,000 hours. This figure is twice the warranty period for energy-saving lamps, which regularly serve 25,000 hours.

LED devices are successfully used in almost all areas where efficient and economical outdoor lighting is required. Provided the right choice is made, the versatility of the product will provide good, high-quality backlighting for a long period of time.

Scope of application of outdoor diode floodlights

Ice floodlights are widely used in public utilities as street lighting of roads, courtyards of apartment buildings, squares, parks, territories of various enterprises, organizations, institutions. Attaching the device to the base at an angle of 100-110 ° allows you to achieve maximum diffusion of the light flux. It is in this way that the illumination of the streets of megalopolises is provided. Lamps of this type are also used to illuminate office buildings, which gives them grandeur.

Useful advice! LED floodlights in their device have a set of diode lamps. If one of the diodes fails, then the other mini-lamps continue to operate with minimal loss of efficiency. This advantage is uncommon for other lighting fixtures besides LED lights.                                                              

Recently, LED lamps have been very popular among residents of private country houses and summer cottages. Thanks to just one spotlight, you can achieve effective illumination of the entire local area, including outbuildings and garden beds. Even a pair of incandescent lamps will not provide such an effect. At the same time, electricity will be consumed less than when using an ordinary lamp.

Lamps are used at night as decorative illumination of monuments, works of art, fountains, plants, objects of architecture and sculptures. As a very convenient type of backlighting, LED lamps are used in billboards, signboards and billboards. In manufacturing plants, floodlights are used to illuminate vehicle fleets, parking lots, gas stations, open workshops and warehouses. Moreover, one LED spotlight works several times more efficiently than several other types of lighting fixtures.

LED floodlights for street lighting: technical parameters and device

When choosing an LED-type lighting device, you need to know its functional features. Such spotlights are usually equipped with a set of diodes.

Power is one of the main indicators of a LED floodlight that consumes a minimum amount of electricity. Therefore, the device requires a minimum mains power to operate. The luminaire requires a minimum of 5 watts to function. The amount of energy consumed depends on the intended purpose of the device. The most widely used LED floodlights are 50W. Such a device, despite its low power consumption, gives a light of 4000 lumens, which provides effective illumination of an area of ​​100 m².

The following technical parameters are characteristic of an LED luminaire:

1. Long-term operation, which means that the device works for a long time without requiring repair and replacement of lamps. One diode in continuous operation mode can last 100 (or more) thousand hours.
2. High efficiency, which reaches 98%. Thus, the luminaires consume energy exclusively for their intended purpose - to create a light flux. They practically do not heat up.
3. The level of protection corresponding to the quality, which must be at least IP65. Thus, the device is protected from dust and moisture. Luminaires with less protection (IP44) are installed in closed places.
4. Safety for people. LED lamps do not pose a threat to health and do not require special disposal, unlike energy-saving mercury lamps.
5. Elementary assembly of the device and ease of maintenance. The luminaire is mounted on special brackets, which allows you to adjust the direction of the light.

Additional technical parameters of lamps for floodlights, depending on their purpose

The size and weight of a spotlight depend on its functional purpose, that is, on the number of diodes and the power of the lamp.

Useful advice! If one LED lamp is out of order, it is very easy to replace it. To do this, simply open the cover of the spotlight and replace it. In this case, you can not be afraid to drop the light bulb, since the diodes do not break under mechanical stress due to the lack of a glass bulb.

For example, in order to provide street lighting with 500 W incandescent lamps, you will need to install a large-sized lamp - from 60x60 cm.In turn, a 50 W LED street floodlight has dimensions of 20x20 cm.

LED street light bulbs come in various configurations. They can be made in the form of a square, rectangle, circle, oval or ruler. These lamps are characterized by additional technical parameters:

1. Wide power supply range - from 100 to 240 volts. If the voltage drops, the LED floodlight continues to work normally.
2. Work with both AC and DC current.
3. A certain number of diodes.
4. Different color of light - hot or cold, different temperature.
5. The ability to change the angle of light scattering. Most often, the angle of installation of floodlights for outdoor lighting is 50 ° or more.

It should be noted that frequent voltage fluctuations adversely affect the life of the luminaire, shortening it. At the same time, the starting block of the searchlight breaks down very quickly.

The choice of lamps depending on the purpose: floodlights of 12 volts and above

When choosing a floodlight for street lighting, there are a number of factors to consider. Often people are guided by the low cost of the product, although the low price does not guarantee the quality and compliance of the lamp with all the necessary technical parameters. An important point in choosing a spotlight is its location.

To illuminate the area around the cottage or near the entrance, the minimum lamp indicators must correspond to 12 volts. An LED floodlight for this purpose should provide a luminous flux of 600-1200 lm. Basically, this is a rectangle-shaped structure that is attached with a bracket to any base. If the area of ​​the local area is extensive, then it is better to opt for a 20 W LED street spotlight.

It is important to consider the degree of IP protection. Outdoor lighting devices must have IP65, which will ensure reliable protection of the product.

More massive and powerful floodlights are used to illuminate parks, squares and sidewalks. Most often these are matrix lamps. The LED array in the device ensures uniform light distribution. The lighting level depends on the height of the luminaire, and the power consumption ranges from 15 to 50 W. The most popular category is 30W outdoor LED floodlight. The light flux at this power ranges from 1000 to 6000 lumens. High wattage luminaires must be placed on tall poles.

For decorative lighting, less powerful lamps are used - from 5 to 20 W with a scattering angle of up to 90 °. Searchlights with multi-colored LEDs look original.

100W LED Spotlights and higher for lighting streets, roads and highways

Floodlights with a power of over 80 W are used for outdoor lighting of large areas, for example, open warehouses, roadways within the city and highways outside of it.

Useful advice! When choosing a floodlight for street lighting, you should pay special attention to the power and luminous flux of the lamp, and only then to other parameters.

For example, the illumination of 1 km of a 7 m wide roadway can be provided by a 100 W LED street floodlight with a total power of 2 625 W (taking into account the idle speed of the drivers). In this case, it is necessary that the luminaire be installed at a height of 9 m, removed from the curb by 1 m, the distance between the supports should be 40 m. Installation of LED lamps, in comparison with fluorescent lamps, saves energy consumption up to 30%.

If the distance between the supports is reduced by 15%, that is, to 34 m, then, accordingly, the level of savings will increase to 34%. This type of lighting using 100W LED floodlights is suitable for illuminating roads in the city, especially in places where pedestrian crossings are located.

150W LED floodlights are used for both outdoor and indoor lighting. They are installed in business and office buildings with a large area, as well as on trading floors and warehouses. They are used to illuminate large shop windows, gyms and advertising banners.

Additional functions of LED lamps: LED floodlight with motion sensor

LED floodlights are subdivided not only according to power, but also by purpose. In accordance with this classification, the lamps are of the following types: for street lighting, industrial and sealed for use in water. The latter are used as lighting inside swimming pools. Therefore, before making a choice in favor of this or that model, it is necessary to determine the purpose of the lamp, its optimal power, size - and only then focus on the price of the device.

LED floodlights can in their design contain such additional equipment as motion sensors, lighting indicators and photo relay... Such functions are very popular, as they not only automate the operation of luminaires, but also reduce energy consumption, providing tremendous savings.

A street floodlight with a motion sensor is very common among the owners of private cottages and houses in summer cottages. This is due to the fact that this device works as needed, while performing not only the lighting function, but also the signaling function: the response to movement helps to determine the presence of strangers on the territory of the estate.

Depending on the location of the device, the outdoor motion sensor can be:

• mounted in the middle of the lighting fixture;
• installed in a separate part of the device, mainly at the bottom;
• placed in a special box,
• produced as a separate add-on for the floodlight.

Useful advice! The use of street LED floodlights on construction sites, where work is carried out around the clock, is especially effective.It is the lamps of this type that provide high levels of illumination of the workplace.

LED floodlight with motion and light sensor: features and benefits

Luminaires with sensors and indicators, in addition to the characteristic advantages of such devices, have a number of additional advantages, including the following:

1. Profitability. Devices with motion indication function provide savings of up to 70%. For example, incandescent bulbs require a power consumption of 300 to 1000 W to provide bright lighting, while LED floodlights will consume 20-150 W and operate when needed.
2. Durability. The outdoor LED floodlight with high quality motion sensor can work properly for up to 100 thousand hours. It is noteworthy that the service time is not affected by the number of on and off operations.
3. Almost all lamps with motion sensors additionally equipped with light sensors, which is the response of the device to the degree of daylight.
4. Operation in different climatic and temperature conditions. Luminaires with sensors can last a long time at temperatures ranging from -40 to +50 ° C.

It is necessary to take into account the following feature: in hot summer, the difference in temperature between the air and the human body may be small, therefore the indicator of the distance of the moving object and the speed of the sensor's reaction may weaken slightly. The LED floodlight with motion sensor for the street achieves the highest degree of sensitivity during the perpendicular movement of the object in relation to the sensor indicator.

How to connect a motion sensor to an LED spotlight

Basically, LED devices have a built-in motion sensor, which does not pose any problems in the process of connecting them to the network. It is enough to thread the cable into the terminal box, then it is necessary to gradually connect the phase (L), zero (N) and ground wires to the terminal (icon with three perpendicular dashes and a stick at the top).

Important! Work on installation in the mains and replacement of LED lamps for the floodlight should be carried out only if the power supply is completely disconnected.

How to connect a motion sensor to a floodlight if it is not part of the main structure? In this case, proceed according to the following connection diagram:

• the phase wire is connected to the sensor;
• the zero contour is divided and directed to the lamp and the movement indicator;
• an additional wire connects the lamp and the sensor.

Before connecting an LED spotlight, you need to familiarize yourself with the structure of the infrared indicator. This is an electronic device that assumes a luminaire with a set time interval after fixing an action from a thermal object. The device is equipped with three adjusting knobs necessary for flexible adjustment of operating parameters:

• SENS is a sensitivity adjuster. The maximum range is 12 meters;
• TIME - setting the time period during which the spotlight works;

• DAY LIGHT - adjustment of the light threshold, upon reaching which the sensor is triggered.

Setting the SENS, TIME and DAY LIGHT controls to an intermediate value will help you select the conditions that are optimal for the luminaire to function.
