The strategy of installing lighting fixtures involves selecting and evaluating equipment - an LED spotlight. Now, for every taste, you can pick up a device with a motion sensor for the territory of a private house or automatically turn on the lighting of garage doors. How should I choose a spotlight?

Searchlight fumbles around the hill
Initially, the searchlight, as a light device, concentrating the stream of light in a limited spatial segment with the use of optical instruments, was used in military affairs. Then the searchlight began to be used for flooding light when illuminated by scenery in the theater, buildings and scenes.
Over time, the design and functionality of the searchlight found application in the created LED devices.
Today, LED products have successfully replaced traditional incandescent lamps. The explanation of the replacement is the qualitative indicators of LED lamps, lamps and searchlights. Recall that this is a dense light flux of high efficiency. With minimal consumption of electricity, the light flux is bright.
Therefore, LED lighting models are used everywhere for lighting streets, private houses and public buildings.
LED spotlights (LED) is a practical solution for lighting areas of suburban areas, construction sites and sites.
Certainly, that the model has a worthy application, it is necessary to select it rationally. A variety of assortment of LED devices evokes the idea: "How to choose a LED spotlight".
Enrich your own knowledge of LED spotlights will help evaluate the technical characteristics and working elements of the device.
About technical characteristics of searchlights
When choosing and evaluating the capabilities of the LED device, it is necessary to pay attention to the parameters:
• Operating voltage and angle of dispersion
• luminous flux power
• Energy consumption
• color of glow
• Class of protection.
According to the design, LED floodlights are the owners of voltage from 12V to 110-260V. The angle of dispersion of the luminous flux in practically most of the projector models is 120 °.
According to the power, the LED projectors are divided into the main groups: small, medium and high power. Low power luminaires have a power from 850 to 1100 lm.
For example, the model of the LED sudo-2 projector, with a power consumption of 10 W and 850 Lm is an excellent option for lighting city billboards and architectural lighting of the facades of country houses.
For medium-power devices, the luminous flux is between 1,200 and 1,900 lm.
At floodlights of considerable power the luminous flux can reach 11000 lm. For high-power searchlights, the light source is built-in SOV chips (Chip-on-Board). Naturally, the orientation at the choice of the power of the flow of lighting should pursue the goal of lighting: either it will be a modest illumination of the suburban area, or a total luminous flux for the objects of the protected zone.
Detailed information about the technical parameters of the projector is concentrated in the marking located on the back cover of the device
LED Spotlight Design
The design of the searchlight is simple (the military military past is affected). Therefore, tremendous vibration resistance and reliability of continuous operation of the device up to 90,000 hours can be considered the best qualities of the device.
The components of the construction are:
• metal casing made of die-cast aluminum alloy coated with anticorrosive enamel or powder coating
• Mounting bracket or bracket
• power supply and driver for its supply
• radiator for heat removal
• LED matrix
• supply wire
• protective glass.
Light source - LED matrix is a compact assembly of crystals, sealed with a layer of polymer.
The LED assembly is pressed on a thin copper substrate attached to the body of the device. Assemblies can have a power of up to 100 watts and depend on the number of LEDs.
By the way, you can assemble a simple searchlight from the factory components yourself.
The design of the projector assumes an equally simple connection scheme.
How to connect a spotlight
According to the scheme of connecting the spotlight to the switch box, where the installation is recommended, a three-wire cable is supplied. For the metal case, it is absolutely necessary to ground: the PE wire, the phase for the break and zero to the spotlight or the instrument cluster.
The connection diagram allows you to additionally enter the motion sensor.
For example, the LED floodlight asd with a motion sensor is designed for places where the regular need for lighting is periodic. Manufacturers of floodlights with motion sensor ASD Group provided the maximum convenience when installing the device.
Installation and installation of a high-efficiency spotlight are carried out on the support surface with a clamp.
How to enter a floodlight with a sensor in the circuit, shown in the video.
For outdoor lighting of private houses, landscape elements and pools, it is possible to connect a multicolor LED spotlight RGB. In this case, it is necessary to provide and lay the control panel in the circuit.
The rules for choosing a spotlight on light-emitting diodes
determine the location
Having estimated the technical characteristics of the devices, it is possible to proceed with the selection criteria.
Initially, decide what you want to light and where to place the searchlight. You can place the searchlight on a support, a wall of a house or a building, on a ceiling of a terrace or a gazebo, and also in a fountain or a path. For these purposes, a floodlight housing with dust and waterproof design is justified. If you intend to use the LED device to illuminate tracks and sidewalk, it is recommended to use a searchlight with a motion sensor.
we estimate the level of illumination
In order to understand the significance of the luminous flux, we will suggest that for lighting the car park 75 lux will be required, for working in the evening hours in the workshop of 100 lux, 10 lux will be enough to illuminate the lawn or recreation area. However, these requirements for spotlight illumination are not mandatory.
select a color mode
Depending on the location of the spotlight, it is recommended to choose the color temperature or color mode of the device. We recall that the luminescence temperature is of the following types:
• Warm white (2700K)
• neutral white (4000K)
• Cool white (6000K).
Let's say that for lighting is given preference to warm white light, and for lighting facades, steps and areas - a neutral color scheme. Cool white is the best lighting option when working with a searchlight mounted on a tripod when carrying out work in the evening.
In order to better understand the purpose and location of the luminous flux, it is recommended to make a simple estimate of the value of the searchlight range. The coefficients of use of the light flux, margin and unevenness of illumination are used for the calculation.
For calculation, you can use the calculation program from the Internet. Undoubtedly, the obtained values of the searchlight range will be estimated, and have some deviation from de fasto.
spotlight shape and type of execution
Projectors from the manufacturer, such as the LED jazzway searchlight, can have classic square or round shapes and are mounted permanently, on a tripod and be portable. The square shape of the searchlight became a permanent inhabitant of the street territory.
But a special refined flow of lighting creates round floodlights, used to illuminate the landscape, facades and architectural forms. Collected in small groups, round spotlights create original spot lighting. And the mounting hardware for fixing helps.
fixtures for fastening
The design of any spotlight offers the possibility of their simple installation in place. To do this, use brackets and accessories.
Fixtures and mounting brackets can be wall-mounted (double and single), parapet (rotary) and with adjustable removal.
