    Advantages and disadvantages of Chinese LED lamps

    The main advantage of Chinese LED lamps from China is their low cost. Delivery from China is cheaper than from any other country. In recent years, Chinese manufacturers of LED equipment have paid particular attention to quality. Accordingly, the quality of LED lamps from China is often not inferior to the similar characteristics of European products. types of LED lamps

    Modern Chinese technologies, which are used to design the schemes of the operation of LED equipment, are still far from the limits of their own capabilities. Experts believe that currently no more than 10% of the actual capacity is involved. And this is at the time that the LED resource on average is 100 thousand hours of operation.

    Build quality of LED luminaires

    Large Chinese manufacturers mostly care about the quality characteristics of their products:

    • uses high-quality components for the production of products;
    • use research laboratories;
    • monitor the quality of each LED lamp separately.

    In small companies, the situation looks different. Small Chinese manufacturers of LED equipment are saving on both components and labor. As a result, the price of such products is much lower, like the quality of LED lamps. Sellers assure that the lamp will last long but knowing about the quality of Chinese LED light bulbs is not so. The juice of the service depends on the quality of the parts and often the lamps do not serve even the year

    To assess the quality of the assembly it is enough to disassemble a few Chinese LED lamps. When disassembling, special attention should be paid to the presence of adhesive on the board and the quality of the soldering. By the last criterion one can judge the quality of the whole product. It will not be superfluous to be convinced of absence on a case of an LED lamp of chips and cracks. Poor-quality assembly of such lighting products often leads to the failure of a part of the LEDs and the lamp as a whole. Thus, the answer to the question why the LED bulbs blink and why the LED bulbs burn out is obvious. The fault is poor quality assembly. led-lampa

    In addition to significant savings on LEDs, Chinese are often trying to reduce costs by using electrolytic capacitors in the driver circuit, which dry completely during the year of operation.

    As one of the most significant parameters of LED lamps is the heating temperature of diode elements. If the heat sink is not good enough, overheating and subsequent destruction of the diode crystal occurs. This reduces the brightness of the lighting fixture.

    As you know, the lifetime of the LEDs is calculated in hours. So, if the lamp indicates a figure of 25 thousand hours, it means that after the specified period the lamp will shine 30% less intensively. But this standard applies exclusively to branded products. Many Chinese manufacturers indicate a service life of 25 thousand hours, forgetting to mention that the quality of lighting by LED lamps will fall after that not by the standard 30%, but by as much as 50%:

    What problems arise with Chinese LED lamps

    More oftenall with Chinese LED lamps, the following problems occur:

    • the power of lighting devices is lower than declared by the manufacturer;
    • brightness of lighting devices is lower than declared by the manufacturer;
    • flicker of light bulbs;
    • non-comfortable lighting color
    • inability to work with switches operating with the indicator;
    • small lighting angle.

    If you take the characteristics and disadvantages of the most widely used in the world market of LED lamps from China and formalize them in the form of a single summary table, the result will look like this: lamp

    The table clearly demonstrates that none of the bulbs under consideration does not provide the light flux that is indicated by the company-producer. The best option is not more than 84%, and the worst is about 30%.As for the CRI color rendering index, this indicator should normally be more than 80. All LED lamps from China do not reach this index. This means that if you light up such rooms with lighting, the colors of all objects in the room will be greatly distorted. As many as seven lamps are not suitable for residential use at all, since they have a high flickering index. With switches equipped with indicators, according to the table, only three lamps work correctly, the others are very weak, since their electronics includes only two capacitors and a diode bridge.

    Some of the lamps considered have a completely uncomfortable lighting color. Most shades have a shade that is simply unrealistic to confuse with the color of a standard incandescent lamp.

    Why the LED bulbs blink

    If you look at the LED light bulb through the video camera, you can find that it is pretty much present. This means that a low-quality driver was used to produce it. The blinking of the lamp can significantly affect the vision. Therefore, if you are not lucky enough to get lighting equipment from China of poor quality, twist them better into rooms where you spend not very much time. For example, a toilet, a hallway or a common corridor. For living rooms it is better to use lamps of better quality with lesser fluctuations of the gezets.

    The easiest way to determine the quality of an LED lamp is to use the camera of a camera or phone. When hovering on the screen appear stripes, if the bands are not visible means the lamp is good and has 100 hertz.

    Why LED bulbs

    burn out The main reason for the burnout of LED lamps( as well as their flicker) is the use of a manufacturer of a poor-quality driver. Often, such a problem is associated with a breakdown of the transformer, which is responsible for lowering the voltage that the lamp receives. It often happens that the light elements burn out. Find out the reasons why LED stripes burn out here.

    To avoid any problems with Chinese LED lamps, pay attention to the characteristics. We should not pursue cheapness and choose the products of those manufacturers who can guarantee the quality of their products. Correctly made choice of LED lamp will please you for many years and will not disappoint.
