Features of LED Spotlights

The spotlight is lighting device, the main purpose of which is to emit light over a certain area... Such models are in demand when arranging sports grounds, parking lots, factory and warehouse complexes.

According to their functions, all types of floodlights are divided into several groups:

• long-range - are used to illuminate objects located at a considerable distance;
• flood light - designed to illuminate theaters, stadiums, car parks and other large areas;
• signaling - are used for data transmission;
• accent - are used for local highlighting of individual areas.

For a long time, mercury and xenon lamps have been used as the basic light source in outdoor floodlights. These days they are giving way to LED and LED matrix luminaires.

Their main advantages are considered economy, reduced power, long service life and low maintenance costs... Therefore, despite the high cost of such lighting devices, in the long term, they turn out to be a more profitable purchase.

Recently, halogen floodlights have appeared on the market, so the question arose about which lamps to prefer. Halogens are considered by many as an alternative to LED. The low cost speaks in their favor - such products are one third cheaper. However, halogens consume 5 times more energy, and their operating time is 10-15 times shorter. Thus, for a year of regular use, the cost of a halogen lamp will many times exceed the cost of maintaining LED lamps.

Due to the design features of any LEDs, such installations demonstrate a narrowed angle of emission of the light flux - it is about 120 degrees, therefore it is difficult to give an unambiguous classification of such light installations.... In this regard, the concept of "LED-spotlight" combines any devices with LEDs, in which the lighting elements are fixed on a single plane.

Such devices are small in size. They are in demand both in everyday life and in industrial production. The benefits include:

• long service life - up to 50 thousand hours;
• performance at temperatures from - 35 to +45;
• reduced power consumption in comparison with traditional lamps - to provide a continuous luminous flux of 80–90 lumens, only 1 W of power is sufficient;
• lack of sensitivity to power surges;
• low heating temperature;
• resistance to mechanical damage and strong vibrations.

There are many different types of LED floodlights. Depending on the scheme of work, there are four main types of installations.

The design of such devices is a linear matrix in which the LEDs are placed in one row. This option is optimal for decorative lighting of window openings, as well as exhibition and cultural and entertainment centers.

This LED mechanism is characterized by the dense arrangement of individual lamps on an aluminum substrate. This ensures efficient heat dissipation. This technique is called COB, in other words - Chip on Board. It helps to significantly reduce the size of the LED module and increase the service life of the crystals. These spotlights give a bright and even glow along their entire length.

Single-color installations that emit radiation exclusively in one spectral shade: yellow, white, as well as blue, red or green. They are distinguished by their structural simplicity and low energy consumption.

Based on the use of basic shades: red, blue and green (in conjunction with the controller). This scheme allows you to get a variety of color combinations. The controller can set the speed at which the colors change, and also provides a wide variety of lighting effects.

The list of the most popular LED floodlight manufacturers includes the following companies:

• D-Energy;
• Novosvet;
• ERA;
• Orbis;
• Globo;
• Falcon Eye;
• Feron;
• Wolta.

They offer the most practical and efficient luminaires in a wide range: diode, explosion-proof, hand-held mini-fixtures and many others. They are in high demand due to their favorable cost / quality ratio. The top of the most popular lamps includes models that can be installed in the yard, in the country or in production halls throughout the year, regardless of the weather. We offer an overview of the best models according to users' opinion.

Medium brightness equipment, gives cold white light... The power corresponds to 30 W. Has a long term of use, can tolerate frosts down to -35-40 degrees.

High quality mini-floodlight, power - 20 W, is in demand for the organization of lighting for summer cottages and the local area. The spectrum is cold white. It is characterized by resistance to adverse weather influences. It is activated both from the electric current network and from the battery.

This LED torch gives white neutral light. It belongs to the group of the most powerful LED floodlights: its power is 40 watts. The design provides side elements, thanks to which the luminaire is fixed to a wide variety of surfaces.

The power of this highly directional luminaire is comparatively low - only 10 watts. However, it is quite enough for highlighting the gazebo or the area near the porch. The color temperature is cold, the spectrum is white. The device is characterized by low power consumption, therefore its operation is quite economical.

A neutral white device, quite bright, with a power rating of 50 W, optimal for organizing the lighting of a spacious courtyard and garden.

Powerful 50 W lighting fixture, bright white lighting. It is offered in a steel case and is resistant to rust. This floodlight is resistant to water, UV rays and temperature fluctuations. It can be installed on any part of the street or industrial complex where there is a need to illuminate large areas. The service life of such a model is 35 thousand hours.

The power of such a floodlight is only 8 watts. Such lamps are placed right next to the house. Operation from a solar battery is provided. There is a sensor that can pick up movements from 5-6 m.

LED device with a neutral glow, suitable for installation near the entrance area or near utility blocks... The power corresponds to 6 W.The advantages of such floodlights include increased resistance to any natural influences.

One of the brightest 100W LED luminaires. Available in a dark durable metal case. It can cope with all assigned tasks in the rain and in polluted environments. Works at temperatures up to +40 gr.

The body of such devices is made of duralumin or aluminum. This ensures high-quality heat dissipation of the module and reliable protection. The internal scheme provides for:

• power supply unit - serves to transform the incoming mains voltage of 220 V into a constant one;
• LED matrix;
• reflector;
• sturdy glass for protection;
• a set of seals preventing the penetration of water into the body;
• terminals for power supply.

When choosing an LED luminaire for street lighting, a number of fundamentally important factors should be taken into account: this lantern must give a bright light, be resistant to adverse influences, and also be economical.

The power of the luminaire directly affects the brightness of the glow. The optimal parameters are selected individually, taking into account the tasks assigned to the floodlight, that is, what area is planned to be illuminated and where exactly it will be installed... On average, a 24-36 W device will be enough to illuminate the entrance area, and if you need to illuminate a significant area, then the power should be 50-70 W. For work in stadiums, models for 150, 300, 400, 500 and even 1000 watts are relevant.

Any outdoor lighting fixtures must be highly resistant to dust and precipitation. Models are considered optimal if their indicator is not less than IP64, and preferably even higher.

To illuminate the territory, the best solution will be lamps, the body of which is made of aluminum. Plastic ones are worse at coping with the assigned tasks, they are more likely to break. Alloys based on aluminum with some other metal have proven themselves well. However, it should be borne in mind that in this case, corrosion processes can begin in the joint zones.

With constant use, even the most economical flashlights will consume a lot of electrical energy, therefore, when purchasing a LED-based floodlight, it is better to give preference to devices with a motion sensor. In this case, the light will light up only when a pedestrian approaches.

Some floodlights are powered by a battery, others are powered exclusively by 220 volts AC. If you intend to illuminate suburban areas where there are frequent power outages, then stand-alone models are a practical solution.

Color rendering parameter - when choosing a spotlight, it is very important that the light does not irritate the organs of vision. In this case, you need to pay attention to the characteristics of the CRI:

• A1 - shopping and warehouse complexes;
• 2A - residential apartments and houses;
• 1B - schools and universities;
• 3 - industrial premises;
• 4 - unsuitable for indoor use.

Color temperature is another fundamental parameter responsible for the shade of the glow:

• bright yellow - for street areas;
• warm white - for a residential building, catering enterprise or hotel;
• neutral white - for residential buildings and apartments;
• cold white - for industries, hospitals and warehouse complexes;
• bright white - for shops and art studios.

If you intend to install an LED floodlight in your country house or local area, the choice must be made taking into account the protection class. The optimal indicator will be IP65. In all other cases, the device will break down very quickly under the influence of wind, dust particles, rain and snow.

When buying street models, attention should be paid to their shape. Round backlights are ideal for illuminating a specific area with directional illumination. If you need to uniformly illuminate a large space, it is better to give preference to devices in a square case: they will give diffused lighting.

If you want to buy a spotlight for a garage, then rectangular or square models will be the best solution. They will evenly illuminate all areas of the room. The color temperature should be neutral, in extreme cases bright white: such shades increase activity and invigorate.

Protection for luminaires in garages is not so fundamental, since here the device is not exposed to precipitation and wind.

According to the use case, there are several types of spotlights:

• for architectural structures and shields;
• for interior lighting in the interior;
• for underwater lighting;
• soil;
• stage;
• automobile.

LED installations are in demand for the organization of highlighting advertising signs and all kinds of buildings. These luminaires can use a wide variety of LED shades, so that even the most intricate design ideas can be realized. The basic criteria for choosing such luminaires are the angle of the light beam, as well as the level of moisture and dust resistance (it must be at least IP 65).

Installations for street lighting used to illuminate small garden areas and paths. The main factors for them will be the slope of the light flux, its power data, as well as protection.

Underwater spotlights make it possible to organize the lighting of pools, artificial ponds and other reservoirs. The main criterion for them will be the level of moisture resistance (it must be at least IPx8).

Soil installations mounted in the soil and fixed in road surfaces. In addition to power, the important factors of choice for them are the security indicator (at least IPx6), the strength of the protective glass and its resistance to mechanical stress.

For the design of special effects, LEDs of basic shades (blue, red and green) are used. They help organize the most complex color schemes.

Luminaires are singled out separately for plants.
