What are the spotlights - 5 main types

A serious problem is the issue of lighting a room or a large area. After all, a lighting device should not only illuminate the terrain well, but also reasonably consume electrical energy. In addition, the lamp should work without interruptions, be convenient in operation and maintenance. There is a wide range of similar devices and withchoosing a spotlight it is necessary to take into account the advantages and disadvantages of each. In this article we will consider the existing types of spotlights for outdoor lighting and indoor.

Halogen

Halogen lamps provide a shadowless spotlight with a warm shade. Such types are often used to illuminate billboards or building facades, as well as to illuminate large objects (for example, dams or bridges).

Halogen light source

The principle of operation of the device is similar to the operation of an incandescent lamp, except that halogen is added to the gas, with the help of which a powerful stream of light arises. There are varieties of spotlights that work from a transformer or power supply, as well as directly from a standard network.

What are the advantages and disadvantages of the product? The advantages of this device include low cost, high reliability and compatibility with a dimmer. Thanks to this, the spotlight is easily adjustable and adjustable. Halogen lights last up to 4,000 hours. The disadvantages of this type of lighting include a high degree of heating of the housing, as well as significant energy consumption.

Metal halide

The principle of operation of such a device is as follows: a gas discharge lamp is filled with gas vapor when turned on and emits light. Such a spotlight provides bright lighting with a cold shade. Their luminous flux is powerful and strong. Such types are used in supermarkets, shopping centers, concert halls and exhibitions. In addition, they are used to illuminate construction sites and billboards.

Metal halide lamp

Metal halide floodlights have a long life and work up to 15,000 hours. Another advantage is their reliability and immunity to voltage drops. There is a large selection of models that are well protected from various kinds of damage.

Sodium

This type of spotlight does not have high power and good quality of luminescence. Due to this, they are considered very economical and provide a yellow light with a warm shade. Sodium models are used in places where minimal maintenance and maximum savings are needed. They are used to illuminate highways, roads or streets. Also, such lamps are often used to illuminate landscapes and facades. Sodium lights last up to 30,000 hours.

Sodium lamp

The principle of operation of the device is as follows: electricity is supplied to a sealed flask, inside of which there are sodium vapor. These pairs emit light under the influence of an electric current.What are the advantages of this type of design? Such a product is considered the most protected from various damage.

LED

LEDs are considered the most popular and high-quality light source. The LED spotlight lasts up to 80,000 hours and does not require any maintenance over the entire life cycle.

LED lamp

This type of spotlight is used in almost all areas. Due to the fact that they have a high light flux density, they are used to illuminate a large area. Also, this type of performance has the ability to create all kinds of lighting effects.

What are the advantages and disadvantages of LED models? The main advantages include the fact that they have high efficiency compared to other lighting devices. In addition, the device has good shockproof and protective performance and their characteristics. It works under any conditions. However, the LED spotlight has one, but a significant drawback: high cost. In this case, you can also DIY LED spotlightby solving the problem of overpayment.

Infrared

This type of lighting emits a spectrum of light that the human eye does not see. An infrared spotlight is used in video surveillance systems, as well as in devices that are used at night to illuminate the territory.

If the human eye is not able to detect infrared light, then cameras pick it up easily and the picture is clear and understandable. When choosing a product, it is necessary to pay attention to the angle of radiation, the detection range and the wavelength, as well as the current and voltage that is consumed. The advantages of the product include their efficiency, compactness and low cost. The photo below shows an example of an IR illuminator:
