Pros and cons of LED-type lighting
An LED is a miniature semiconductor device whose task is to convert electricity into rays of artificial light.
This function is performed by specially grown crystals with maximum light output and minimum energy consumption. Diodes serve as both the main and additional light sources.
The ability to shine brightly, eating a minimum of electric current, could not but interest developers of lighting projects for recreational areas, public spaces, industrial and commercial objects.
She was fascinated by the manufacturers of dashboards for various kinds of machines with equipment, manufacturers of home appliances with lighting for convenient operation at night.

The use of LEDs in the organization of lighting provides the ability to implement fundamentally new schemes
LED bulbs consume a minimum of electricity, while emitting the most intense luminous flux compared with incandescent lamps and fluorescent devices
Often, LED light sources are used to create illumination, but can serve as devices for the device main lighting
In the case of installation of large-sized lamps, preference is given to LED options as the most economical and easy-to-use solution.
LED lighting is used in establishments that involve the active use of lighting around the clock
Based on LED lamps, lighting of shopping and sports complexes, hospitals and clinics is arranged.
LED lights illuminate the outdoor pools, areas near cafes, private and public squares, parks, pedestrian streets

It is reasonable to include the advantages of the LED group of devices:
- Practicality. The LED device consumes 10–15 W / h, which is significantly less than the power consumption of a fluorescent light bulb of similar power. Service life is characterized by impressive figures of 30 000 - 100 000 hours.
- Minimum heating. The design of the diode bulb provides regular removal of heat generated during operation of the device. Therefore, the LEDs are in excellent contact with any materials, due to which they are freely used in integrated backlight circuits.
- Variety of sizes and shapes. Presented on the market wide range of LED lightsdesigned to solve various technical problems.
- Ecological advantages. LED-type devices are attracted by safety, because do not contain mercury and other toxic components harmful to the body of users. Disposing them does not dictate safety measures as for fluorescent lamps.
- Strength. The housing and components of the diodes are characterized by high mechanical strength. Their bulbs are significantly safer than incandescent bulbs. In addition, there are no parts suffering from vibration like tungsten filaments.
- Savings during installation. Due to the low power consumption, wiring for a LED lighting device is applied with a cross section that is smaller than the usual dimensions used in incandescent bulbs.
- No flicker. LEDs from the responsible manufacturer do not flicker, therefore, they do not have an extremely harmful effect on the eyes of people in the room.
It should be noted that when turning on the LED bulbs there is no network overload, as it happens when activating lamps with incandescent bulbs. In this case, the luminous flux reaches 95%, while the same competitors have only 60-75%.

For installation in residential areas, it is customary to purchase LED lamps with a predominance of yellow light in the light flux.
Lamps with warm white light are permissible in the device for lighting private houses.
In the lighting of public facilities, production halls, warehouses, LED lamps with white and cold white light are used.
Cold-toned LEDs are rarely used in everyday life; they are more suitable for organizing street lighting and illuminating shop windows.

Ultraviolet radiation is not peculiar to LED devices, but there is still infrared glow in the minimum safe volume.
The list of advantages should include an extensive spectral range, although the characteristics of their luminescence still dominate the cold white rays.
The disadvantages of diode light bulbs are not too many, but it was not without them. The price of lighting devices cannot but surprise, especially those who are not familiar with their specifics. If we take into account the quick payback of LED lighting schemes, then this disadvantage goes into the category of controversial issues.
A similar disadvantage, which can be regarded as advantages in some cases, is the direction of the light flux.
For ordinary lamps, especially for their wall types, this is an obvious minus, for point variants - a clear plus. After all, light is concentrated in a single directional beam.

Most LED lamps are characterized by a limited directivity of the light flux, justified by the specific design of the device.
Because of the features of the device, LED lamps emit light only forward, not illuminating what is located on the side of the base
The ability of LEDs to emit light in only one direction is professionally played up by experienced designers and architects.
A one-way luminous flux perfectly serves to highlight paintings and sculptures in galleries and private collections.
Looks amazing direction of the light flux from the diode lamps in the ceiling, especially if it is a tension and mirror
Due to the fact that the design of LEDs provides for the removal of heat generated during operation, they are used as a backlight for furniture and lamps in suspended ceilings
In non-standard design projects, LED lamps are often very well combined with similar ribbons, neon tubular lamps and filaments.
LED lamps of the new generation can cover 360º, which significantly expanded their capabilities and scope

When connected to the network of industrial frequency LEDs will still flicker, and even stronger fluorescent fellows. Some reasons LED blinking You can figure it out and fix it yourself.
Occasionally, during their work, electrical noise is noted, for example, originating from interference.
For normal operation of the diode bulb requires a clearly rated voltage. To provide the device with a rated operating current, it is supplemented with complex electronic components called current sources.
As a result, the complexity of the scheme increases the cost of construction of LED lighting.
In the most simple cases of the use of diodes, they can be connected to a DC network, but through a resistor.
One of the advantages of LED lamps is their ability to work flawlessly outdoors at low and high temperatures. The main thing is not to turn on the lights on days whose temperature exceeds the limits stated by the manufacturer.
A significant disadvantage of LED devices is considered to be the lack of ability to change the transmission of light. Therefore, they are practically not used in circuits with the ability to adjust the brightness of the lighting.
Only certain types of expensive products can work in tandem with dimmerslowering the flow of light diodes, and then a maximum of 20%.
Overview of LED-products of the brand ASD
Taking into account that the solid amount of advantages unconditionally outweighs the disadvantages of diodes, the demand for them is steadily growing.
Among the devices that are actively in demand in the domestic market, ASD products occupy one of the most significant places. The manufacturer carefully strives to cover the basic needs of the consumer.
Let's look at how to understand the assortment of this brand, what characteristics it is ready to please the future owner, and how to upset.
LED bulbs with the ASD logo attract the buyer with a fairly affordable price and an assortment designed to meet the basic needs of the domestic consumer
Light Bulb Standards
In the designs of all currently known LED devices, almost identical components are used. The difference lies in their size, and sometimes as components.
AT light bulb designs ASD used:
- A group of LED chips. Their total power is the immediate power of the lighting device.
- Control device. Provides on / off light from the network, as well as stabilizes the current supplied to the luminous crystals.
- Body Made in the form of a pear, a ball, a candle flame or a flask tube, equipped with a reflector on the working side and a radiator on the back side to remove heat.
LED chips are mounted on an aluminum board, which plays the role of the base for installing crystals and devices to divert heat flux from the diodes to the radiator zone.
Smooth and regular cooling of the working body significantly extends its working life.
The standard components take part in the construction of the LED from the ASD: a board with diode chips, a control device and a housing with a base and a reflector
Depending on the power, size and purpose of the lamp diodes in the device can be from one to several dozen pieces.
The diodes are connected to the control device either parallel to the “chain” or sequentially, i.e. each separately. The first option is simpler and cheaper, the second is more complicated and much more expensive.
The connection is made through a resistor and a driver, which is responsible for supplying the current values necessary for the device.
In the lamps with diodes connected in parallel, each element is supplied with its own resistor, which explains their complexity and considerable price.
But if one chip fails, the rest will continue to work, and with the parallel version, the entire device will be damaged.
The company produces LED bulbs with standardized bases suitable for installation in operating networks and replacement of incandescent lamps and fluorescent devices.
Variations on the subject of brightness are obtained through the use of optical components differing in properties: scattering and focusing lenses. By this method, light emission is either amplified and concentrated into a beam, or scattered.
LED bulbs for domestic use come with standard caps: threaded and male. Due to this, they can easily replace a burnt-out incandescent lamp in the power supply line with alternating voltage.
ASD LED range
LED devices with the specified logo are produced in flasks made of opaque or transparent light-conducting material.
The assortment has options with pear-shaped, spherical, tubular housings, as well as LEDs made in the form of a candle, a directional light source with a reflector and other types.
In the LED device made by the filament technology, light-emitting crystals are deposited on strips coated with phosphor
According to the type of base for LED chips and fixtures to it, the lamps are divided into models created using the following technologies:
- Svd - work items are attached to a rigid board located in the center of the device in a sequential or parallel order;
- Owl or they LED filament - LED chips in them are fixed on glass, sapphire or metal strips with phosphor coating.
Among the trade offers from the described company there are no light bulbs made in accordance with the technology. Crystal Ceramic MCOB, but it is possible that the range will soon be replenished with such products.
In the new generation of LED devices, instead of a metal plate, a transparent ceramic base is used, to which diode chips are attached on both sides
According to this technology, instead of a metal plate in the center of the device, a transparent ceramic plate with a phosphor coating is placed.
On the plate on both sides fixed chips. This arrangement ensures a uniform flow of light in all directions.
Bulb Selection Guidelines
On the packaging of LED products from ASD are indicated LED lamp specificationsthat you need to learn to make a competent purchase.
In energy efficiency class, all devices offered for sale are marked with letter A, which means that their high performance is combined with moderate power consumption.
The company says that it does not produce devices of a lower class, which are seven in international standardization.
The least effective are the bulbs with the letter G in the marking, which is almost impossible to meet in the characteristics of LEDs of any company.
To determine the power of the LED bulb is better to use a comparative table with the data obtained from practical measurements (+)
The characteristics that require mandatory accounting before purchasing include:
- Power. Diodes shine about 10 times stronger than incandescent bulbs and about 2 times stronger than fluorescent devices. In order to get a real idea of the light flux in watts, the power of the LED light bulb must be multiplied by 9-10.
- Power supply voltage. Its parameters must comply with the characteristics of the network to which the device will be connected. You should not try to use the LED in the line with a different voltage, which can spoil it or cause a circuit.
- Colour temperature. For installation in residential areas it is better to use lamps of a pleasant warm color of 2700 L, diodes of 3000 L are suitable for utility rooms. Devices with a cold radiating spectrum, over 3000 L, are purchased for street lighting and for industrial projectors.
- Transfer color. The higher the color rendering index, the better the lighting conveys the real color. It is indicated in the labeling letters CRI, followed by a numerical expression from 0 to 100 Ra units. Products from this manufacturer are marked 90 Ra.
- Angle of dispersion. It depends on the design features of the bulb, for LED devices it varies from 30º to 360º. Usually for spot wall and ceiling lights, LEDs with a scattering angle of up to 90º are selected, for wall sconces - up to 180º, for table lamps up to 180º.
Among the important indicators that should be considered before buying, also includes a socle. ASD bulbs are produced under standard threaded and pin cartridges, in order to find out this characteristic, just look at the device to be replaced.
Before buying a LED device to replace the old light bulb, you need to see what the base of the previous one was. To simplify the identification, nomenclature numbers (+) are put on the bases.
It is necessary to take into account the period promised by the manufacturer for the perfect operation of the LED. Note that during operation, the lamp will gradually lose its brightness, and when the period is almost exhausted, it will generally dimly shine. This means that the LED light bulb should be replaced.
Contributing to the acceleration of wear can be violations of the rules of use, for example, work in undeclared manufacturer's temperature range or installation in a room that is not intended to organize the LED lighting.
Before buying an LED light bulb, decide on what color and degree of heat light is needed.
Consumer feedback on products
LED bulbs with the ASD logo attract buyers with affordable prices. However, owners of economical lighting devices often attend some disappointment and discontent.
Inexpensive products, unfortunately, are still significantly inferior to offers from Philips or Osram.

The main disadvantages are:
- Real power mismatch declared by the manufacturer parameters. The luminous flux emitted by bulbs is weaker than promised by marking.
- Insufficient color rendering. According to the results of the tests performed, the CRI characteristic averages 70 Ra, which leads to reflections on the use of low-grade diodes.
- Invalid service life, overestimated by the manufacturer approximately one and a half to two times.
However, our unbalanced compatriot is not yet too nagging about the quality of the slightly familiar. he is satisfied with the production of many, which is, in addition, supplemented by a relatively low price.

ASD LED bulbs dim with time. The photo shows on the left a new device, on the right - operated for 4,500 hours
During operation of the device, the phosphor gradually burns out, due to which the luminous flux power drops by about 10%
Real energy consumption is 20-25% lower than that stated in the passport data. Apparently, this is compensation for the increased service life and flow rate declared by the manufacturer.
Can not but rejoice the minimum degree of pulsation, component of 1.32%. By European standards up to 10% is considered the norm.
The luminous flux of the diode lamp under investigation is 20% lower than the 900 lumens promised by the manufacturer, even with the lens removed and in a heated state
While the LED is running, the frosted diffuser heats up to 50º, the heating of the diode chips on the plate reaches 100º. According to the norms, the heating should not exceed 110º
The plastic case of the device is heated to 85º, which absolutely does not affect its strength and shape
With the diffuser mounted on the case, the diode chip system heats up almost twice as strong as without it. Affects poorly designed radiator design

Most consumers recognize that the LEDs of the ASD "work out" the money paid for them. They agree that if a product costs a little, then there is no need to be of high quality.
Such an attitude is a serious mistake that will not stimulate the manufacturer to produce a decent product.
Note that in Europe a completely different approach to the expenditure of own funds. If the light bulb has not fulfilled the period specified by the manufacturer and is out of operation ahead of time, the device seller is obliged to change it.
Similarly, when other shortcomings are detected: a weak luminous flux, an incorrectly indicated color rendition.
It is time for a buyer from the CIS countries that is inexperienced in these matters to become stricter and meticulous in order to get quality products at a reasonable price.
