Electronic photo lighting is designed to optimize the consumption of electric energy. With the onset of twilight, lighting turns on and regulates the intensity without human participation. At dawn - automatically, using a potentiometer, the decaying mode is turned on until completely disconnected.

When covering large areas, such as parking, warehouse bases, garage cooperatives, etc. It is not uncommon to such a photo and street lighting. The use of phototorsel brings significant energy savings and, accordingly, reduces utility bills. The device has a range of settings modes. In everyday life, it will be useful to summer residents and owners of houses with personal plots.
Principles of street photo
The triggering of the contacts of the photothelele occurs at the moment of sunlight enters the device or with the onset of darkness.
- Sensors responding to the light are located on the case or are remote, depending on the type of photothelele. The photo of the photothelle provides for two time modes: winter - summer. Thus, you can adjust the inclusion and disconnection of light depending on the season.
- Such a device is quite economical and is beneficial when installing not only in the entrance for night lighting or industrial areas, the photothelle has the ability to synchronize with the irrigation and irrigation system. An additional device will regulate watering in the early time and after sunset without your participation.
- Progressive systems programmed to save energy resources are part of the housing equipment called “Smart House”. Such an equipment at the house imitates the presence of the owners in the living room and performs their functions to care for the house during their absence or rest. The equipment of the network with LED bulbs significantly reduces electricity consumption.
- When choosing and acquiring a photothelele of lighting, pay attention to the degree of sensors sensitivity. The higher the sensitivity, the more expensive and economical the device of the photothelele. It is advisable to purchase a photo with a smooth control regulator of the shutdown threshold and a built -in timer.
Technical characteristics of photothelele for lighting
When choosing a photo, attention is drawn to the maximum permissible loads. Depending on the number of connected devices, the most permitted loads range from 1000 to 2300 W, depending on the type and model of the device.
- Some models of the photothelele are equipped with a photocell inside the case. Other models are equipped with a timer and a response threshold regulator. Some models have remote photocell sensors. The choice of model and equipment depends on the specifics of operation of the device and installation conditions.
- The device is designed for the nominal operating voltage from the household network 220 W, and the line of operation of the relay sensors from 2 to 2000 (LC) luxury.
- When choosing a photothelele, keep in mind that a reliable degree of IP44 protection allows you to use the open -air device. The hermetic case is opposed to any vagaries of the weather. In devices with such a threshold of protection, the degree of response of sensors is 5 - 50 lux, and permissible temperature changes - from 25 ° C to +40 ° C.
It is worth remembering that with light saturation of 5 lux, darkness occurs, but the outlines of objects are still distinguishable by the human eye. With saturation of 2 lux, deep twilight occur.
Fotorel connection diagram for street lighting
In the photo lighting, the circuit provides for power from a conventional network of 220 volts of alternating current and the switching voltage in the circuit up to 10 amperes.
The attached scheme of the street photo fotorel shows that at the sensor site, an indicator photodiode is used, which works according to the principle of a photocell (HL-1), resistance (R1 and R2) control the functions of the sensitivity of the photothelele.
Options for connecting a photo to external lighting
On the device itself and in the attached instructions for operation, there is a scheme for connecting a photo to the outdoor lighting network. For the installation of a photothelle, an electrician service is not needed. It is not difficult to connect a photochery on your own. It is only required to make a connection in accordance with the scheme.
- For the convenience of installation and connection, the device is equipped with wiring issues with insulation of different colors. The standard coloring for household appliances is usually the following: black - phase, red insulation - switching phase, and blue or green color - zero.
- The connection of the photo is made in the area of \u200b\u200bthe camshaft. On the wall is fixed on the mounting screws of the fototorle box, and mounting wires are displayed. When installing the box, caution is required so as not to damage the wires hidden under plaster under voltage.
- The load switching is carried out by interrupting the phase voltage and turning off it. The zero wire connected to the blue or green wire is necessary for power supply, the operating voltage of the photothelele is up to 230 V. The mounted device has a nominal maximum load capacity of 10 A (2.2 kW).
- If the switching load has increased power, then more sensitive switches are used to control the device.
