How to choose the square led ceiling light

  How to choose the square led ceiling light mainly from the following three aspects to consider:
   1. Look at the radiator: lamp cooling speed determines the attenuation degree and service life of the whole lamp. Lamp beads work long time under the condition of high temperature, light attenuation soon, life is short, and the brightness is too poor ceiling lamp, not to focus on the effect of illumination. Radiator square led ceiling light, the mainstream with integral type radiator, a single lamp a radiating columns, a fan cooling, with copper as heat sinks. The current user is more acceptable way of single lamp beads a radiating column method. In this way will produce each lamp beads light heat rapidly through the radiating column is emitted out, ensure timely cooling. The integrated radiator is all the heat generated by the lamp beads is conducted to the aluminum substrate, and through the radiator, cooling speed. The size of the radiator, aluminum quality affects the cooling speed, but also affect the whole lamp prices.
   2. See the lamp power supply (i.e. transformer): transformer quality also determines the whole lamp life. Lamp beads used for more than 50000 hours no problem, but the transformer if failed, the whole lamp is bright not up. Electronic components, used in the design of transformer transformer determines the efficiency, power factor, stability, temperature rise, service life.  Users do not understand the elements of knowledge, from the transformer size, weight, and consult the manufacturer of electrolytic capacitors used as preliminary judgment. The difference of LED ceiling light price, transformer quality no small proportion.
   3. Understand the lamp brand and package: lamp beads quality decides LED ceiling light lighting effects, packaging technology, heat dissipation effect quality of key factors such as lamp beads. The chip has America chip beads, Taiwan, domestic chip chip. Different brands, price difference is bigger, the lighting effects are different too. Users can know lamp beads scheme through consulting manufacturers, integrity depends on the manufacturer. LED ceiling light special low price, making a lot of use of chip production line lay the rejected product, color temperature, brightness difference is not consistent, short service life, the user needs to pay attention to.(As shown in the product is: led recessed ceiling light SC-XDB008W01)
