The quality of LED lamps

Since domestic producers did not hurry to withdraw the production and sale of LED bulbs on a fundamentally new level of quality, the only option for consumers is a custom lighting abroad.Especially high demand for LED lamps from China although they have questionable build quality.

advantages and disadvantages of Chinese LED lamps

The main advantage of the Chinese LED lamps from China is their low cost.Shipping from China is cheaper than from any other country.In recent years, Chinese manufacturers of LED equipment particularly close attention to quality.Accordingly, the quality of LED lamps from China often does not yield the same characteristics of the European products.

Modern Chinese technology, which made the development of schemes of action of LED equipment is still far from the limits of their own capabilities.Experts believe that now is involved no more than 10% of the actual building.And this at a time that the LED life is on average 100,000 hours.

LED lamps Build Quality

Large Chinese manufacturers often take care of the quality characteristics of their products:

• use high-quality components for the production of products;
• use research laboratories;
• carry out quality control of each LED lamps separately.

In small companies the situation is different.Smaller Chinese manufacturers of LED equipment and carry out savings on components and labor.As a result, the price of such products is much lower, as the quality of LED lamps.Sellers are assured that the lamp will last for a long time but knowing about the quality of Chinese LED bulbs is not.The juice of life depends on the quality of parts and lamps often are not even a year

To assess the quality of the assembly is sufficient to make out a few Chinese LED lamps.When disassembling particular attention should be paid to the presence of the adhesive on the PCB and soldering quality.On the latter criterion can be judged on the quality of all products.Not superfluous will also make sure the case is LED lamps chips and cracks.Poor assembly similar lighting products often leads to failure of the LED lamp, and as a whole.Thus, the answer to the question why the blinking LED bulbs and LED light bulbs burn out why is obvious.All because of low quality assembly.

addition to substantial savings on the LEDs, the Chinese often try to reduce costs through the use of electrolytic capacitors in the driver circuit, which is completely dry for the year of operation.

As one of the most significant parameters of LED lamps is heating temperature of the diode elements.If enough heat is good, there is overheating and subsequent destruction of the diode chip.This reduces the brightness of the lighting device.

As is known, the life of the LEDs is calculated in hours.So, if the lamp contains the figure of 25 thousand hours, which means that after a specified period of light will shine up to 30% less intensively.However, this standard applies only to branded products.Many Chinese manufacturers indicate the life of 25 thousand hours, forgetting to mention that the quality of the lighting LED lights will fall after that not to the standard 30%, and all 50%:

What problems arise with the Chinese LED lamps

most often with the Chinese LED lamps, the following problems occur:

• power lighting is lower than specified by the manufacturer;
• brightness of lighting is lower than declared by the manufacturer;
• flickering light bulbs;
• not comfortable color lighting
• inability to work with switches operating with the indicator;
• small angle of illumination.

If we take the characteristics and disadvantages of the most common in the world market of LED lamps from China and arrange them in a single summary table, the result will be as follows:

The table clearly shows that none of the examined light bulbs does not ensure that the luminous flux, which is designated by the manufacturer.The best option is not more than 84%, and the worst - about 30%.As for the color index CRI, the norm of this figure should be more than 80. All LED lamps do not reach China until this indicator.This means that if such lighting fixtures to illuminate the room, the colors of all the objects will be greatly distorted in the room.As many as seven lamps generally not suitable for residential use, as they have a high rate flicker.With switches equipped with LEDs according to the table work correctly only three lamps, other burn very poorly because of their electronics includes only two capacitors and a diode bridge.

Some lamps have discussed quite comfortable color lighting.Most of shades is a shade that is simply impossible to confuse with the color of a standard incandescent lamp.

Why blinking LED lights

If LED bulb look through the camera, you may find that it is strong enough to attend.This means that during manufacture unused defective driver.Blinking lights can significantly affect vision.So if you are unlucky enough to purchase lighting equipment of poor quality Chinese, it is better to drive the rooms where not spend a lot of time.For example, the bathroom, the hallway or the common corridor.For living rooms is better to use the best quality lamp with a smaller Getsov fluctuations.

The easiest way to determine the quality of the LED lamp, is to use a camera or camera phone.When the mouse on the screen appear the band if the bands means invisible light is good and has a 100 hertz.

Why burn LED bulb

main cause of burnout LED lamps (as well as their flickering) is the use of low-quality manufacturer of the driver.Often, this problem is associated with the breakdown of the transformer, which is responsible for the voltage drops that receives light.It often happens that burn light elements.Learn the reasons why burn out LED tapes here.

To avoid various problems with Chinese LED lights, pay attention to the specifications.Do not chase cheapness and choose the products of those manufacturers who can provide a guarantee of quality of its products.Correctly made LED lamp will give you a choice for years to come and will not disappoint.
