LED dimmable lamp: a new cost-effective device

The traditional light bulb that shines brightly, but it consumes a lot of energy, came dimmable LED lamp. The products are designed for a special technology that allows you to smoothly adjust the light intensity. This feature not only saves energy, but also has a beneficial effect on human health. The popularity due to the device, described in detail in this article.

How does the LED lamp

LED lamp appearance is no different from the traditional light source. The device design standard socket provided with a conventional thread. Therefore, the lamp can be used for conventional cartridges that eliminates the need for changes in electrical facilities. However, these devices have significant differences on the internal configuration.

The design consists of the contact base, the body that performs the function of the radiator, power board and control board with LEDs and a transparent lid. These devices can not be used for network 220, since they will not work with such voltage and current. To eliminate burnout lamps lamp housing additionally equipped with the power board and control that reduces the voltage and rectifies the current.

The operating principle of the LED lamp is based on physical processes, the essence of which is to occur at the point two contact elements of different materials, the light flux immediately after through these substances was missed electricity. The main paradox of this phenomenon lies in the fact that both elements are semiconductors, capable of flowing an electric current only in one direction, and it is provided that they are connected between themselves.

There is also a transition from one state of matter into another, which is accompanied by release of thermal energy. The electronic device can not only conduct current, but also emit light, called light-emitting diodes. Such elements cover the whole range of light emission. In this connection distinguish LED bulb blue with cold light source and a yellow or red - with the effect of a warm glow.

Dimming LED bulbs: what is it

The main difference from conventional dimming lamps is the presence of the dimmer for LED lamps in the chassis, thanks to which continuous adjustment performed lamp brightness. Output power dimmer parameter is the main device. From its value depends on the maximum number of connected lamps. The dimmer works as a rheostat. It allows you to smoothly adjust the brightness of incandescent lamps.

LED lamp with a dimmer unit is equipped with the function of the pulse-impulse modulation. It is intended for stabilizing control, located in the housing unit, whereby changing the illumination brightness. Adjusting the intensity of the radiation occurs by being supplied to the LED voltage. Used herein sinusoid, wherein the time period energized respectively equal to the value of time without voltage. To increase the brightness necessary to increase the supply voltage, and to reduce it should increase the amount of time without strain.

Important!Through the dimmer you can not connect a standard energy saving lamp. The device is designed for a certain number of cycles, and the constant flashing would facilitate rapid burn bulb.

Changing the frequency of flashing bulb is transparent to the human eye, resulting in illuminance varies in the range of 10-100%.

Types Dimmer for LED bulbs

According to the control method dimmers are distinguished:

• rotary;
• rotary pushbutton;
• keyboards;
• touch.

Rotary dimmer light intensity is carried out by means of a rotary knob. Swing-jacking devices are actuated mechanically by pressing on the knob. During its rotation occurs brightness adjustment bulb. The degree of illumination devices selected keyboards manner repeatedly pressing the button. Select the desired mode on the touch dimmer is carried out by means of a finger touch on the control panel.

Today you can buy a dimmable LED lamp of special design, in which thanks to the light touch of a button, situated in the central part of the panel, the light is turned on, a long touch - decreases or increases brightness lamps.

Depending on the device's location may be:

• monoblock, or patch;
• modular;
• embedded.

In the first embodiment, it is combined with a dimmer switch. Modular units are mounted on DIN-rail in the control cabinet. Such devices are typically mounted in the stairwell. They often choose the owners of private houses. Devices operate basic functions of adjustment and hidden from view. The last type of dimmer is built in a special installation box.

Depending on the functional characteristics distinguish dimmers:

• mechanical;
• electronic;
• remote;
• Acoustic.

The work of mechanical devices is controlled by the wheel button. Device configuration is performed manually. Electronic devices are equipped with sensors, touch panel and automatic. Remote devices are able to receive the signal at a distance, so the adjustment of the degree of illumination can be carried out using the remote control. Acoustic devices triggered from cotton or a voice command.

The most popular are turning devices, which are mounted in podrazetnik. These devices are easy to install, operate and have low cost.

Benefits dimming of LED lamps

Due to the fact that the construction of dimmable LED lamp includes a special driver, you can adjust the light intensity. When there is no need in the lighting unit at full capacity, it is possible to reduce the brightness. This will help reduce the cost of electricity as a result of economical energy consumption. Smooth regulation of the intensity will extend the life of the lamps.

By means of dimmers can be carried out zoning premises, set bright accents or change the atmosphere in the room. Such devices are often used to create a colorful and dramatic effects for presentations or promotions. Using dimmers beneficial effects on human health. After a sharp turn on a bright light there is an unpleasant feeling of light perception pupil of the eye, and dimmable LED lamps can be switched on at once by only 10%, gradually adding intensity that will not lead to injury eye. With the integrated dimmer, LED lamp emits UV rays and IR spectrum.

Dimming the lamp can be combined with a motion sensor, which will signal to automatically turn on illumination. The combination of dimmer and light sensor will automatically adjust the artificial lighting for natural. Current models can have a soft start function or timer.

Useful advice!Using dimmers in an empty room, you can create the effect of presence, when owners of the house are out of town. This may be a good security system, which will automatically turn on and off lights in different rooms.

LED dimmable lamp: Selection Criteria

The first thing you need to pay attention when choosing a dimmable LED bulb, this shape of the device. It depends on the desired lighting effect in the room. Also, the nature of the lighting will affect the state of the protective cap, which can be transparent or opaque. In the first embodiment can be obtained saturated stream glare. The product with frosted glass, which is coated inside a special coating, provides a smooth, pleasant light.

Light the lamp pear shape will be sent down, leaving the ceiling circular shadow. The product has a classical form of the lighting angle to 240 degrees. For open floor lamps and chandeliers, it is advisable to use a dimmable LED lamp e14 in the form of a sphere or a candle light with 240-360 degrees angle.

For illumination of a specific area used reflector type headlight that narrow light beam. For suspended or suspended ceilings used accent lights spotlights. The elements do not emit heat, so they can be mounted in furniture. The angle of illumination of these lamps is 100 degrees.

Another criterion is the degree of light flicker, which is especially important for the dimming of LED lamps e27, which are often used in residential premises. Completely eliminate this phenomenon is impossible. Therefore, you should give preference to products that have a weakly expressed flicker. Can determine it in this way. During operation, the device must be set man look from one object to another. At this time, there is a second slaboskopichesky effect when the human eye can see a few items.

Important!If the luminaire has a strong flicker, it is not suitable for living rooms.

Further attention should be paid to the level of dimming. The minimum value for the dimmable led lamps is 10%. This suggests that at minimum brightness product shines strongly enough. Lamps should choose the lowest limit of the on-off switch.
