Recently, LED equipment has become quite popular among consumers.
Why LEDs? Because it is:
• environmental safety of the devices, the absence of mercury and heavy metals;
• economically profitable to operate, because with a small amount of electricity consumption they emit enough light;
• warranty period for LED bulbs from 3 to 5 years;
• absence of flicker and ultraviolet radiation;
• LED devices almost do not heat up, so they can be used for stretch ceilings, as well as medical and scientific equipment;
• the service life on average reaches from 35,000 to 100,000 hours, which is much longer than the period of operation of traditional incandescent (halogen) and even energy-saving (fluorescent) bulbs.
Dimmers for LED bulbs
LED equipment includes: bulbs, strips, ceiling panels, spotlights and lamps. Consumers who decide to install such devices also need to buy accessories for LED equipment.
To adjust the brightness of LED lamps, special devices are designed - dimmers. They are slightly different from dimmers for halogen lamps. The brightness of incandescent lamps changes by increasing or decreasing the current passing through the device. This method cannot be used for LEDs, because in this case the efficiency of their operation decreases, as well as the color of their glow changes. Therefore, the brightness of LED lamps is adjusted as follows. Direct current pulses are applied to the LED. The brightness of the LED glow varies depending on the width of these pulses. Flickering will not be visible, because the pulses are applied with a high frequency, and the human eye can only see a uniform glow.
Regulators for LED lamps can be of different designs. For example, dimmers built into the wall and with remote control. Infrared rays and radio signals can be used for remote controls. The advantage of the radio remote control is that it works even without direct visibility. It is so convenient to adjust the brightness of the LED lamps without having to enter the room. The advantage of dimmers is the saving of electrical energy, because the consumer can set the required brightness mode for one or all rooms.
Motion sensors
Motion sensors are designed to save electrical energy. These devices are also used to protect various objects.
Motion sensors come in different types:
1. By location, they can be: internal, peripheral and perimeter;
2. By the principle of operation, motion sensors come in: infrared, ultrasonic, microwave, active and passive.
Connecting such devices is quite simple. To do this, you need to connect the sensor cable to the wiring.
You can install motion sensors in several ways:
• it is easiest to install the sensor in parallel with the switch. In this case, the functioning of each device will not depend on each other. The light will turn on when you press the button and approach the object.
• with a serial connection, one switch and one sensor are connected in a chain, which will respond to movement only when the light is off.
• a combined method is to connect the sensor to the electric current circuit.
Transformers for LED strips
Today, LED strips have become very popular, which are used not only for street and advertising lighting. They can be used in the office and at home to illuminate the necessary objects and create an individual style of the room. For stable and long-term operation of the LED strip, a transformer is required. It is used to connect devices that operate from a power source with a voltage of not 220 volts, but 12 or 24. When choosing a transformer for an LED strip, it is necessary to take into account power, voltage and moisture protection.
For reliable and stable operation of LED equipment, special components are required. It is advisable to take their purchase seriously. The specialists of our online store will help you decide not only on LED devices, but also tell you which devices will make their functioning better and more convenient for consumers.
