Lampu Jagung LED
Produk ini memiliki ciri kecemerlangan yang cerah, yang dapat ditingkatkan karena tidak adanya diffuser.
One of the shortcomings of "corn" is the high temperature of the incandescent lamp, reaching 4000 K, which negatively affects the work of the visual organs. However, there are several types of such lamps that have greatly reduced heat generation.
Light bulbs are used in homes and offices, shops, salons and public places. For rooms with children, it is recommended to install lights with a color temperature not exceeding 3000 K
There are three types of LED corn lights:
Classic-high-quality diodes with a power of at least 0.15 W are installed;
Small sub-light bulb-bad LED, up to 0.08 W;
The chip on board is a modern design using COB diodes. Low color rendering brings all these products together. Usually, they are produced without capacitors, which is why they flicker and hurt the eyes. By soldering such components into the circuit, you will improve color rendering and eliminate one of the negative effects.

The LEDs of the SMD 5630 or SMD 5730 model are installed in the classic "corn" model. The diode power used by the company that has been producing for many years is about 0.5 W. The physical parameters of the components used by the Chinese manufacturer are much lower, but the installed crystal To be weak. The nominal characteristics of products have improved, but they have not shined better since then
Main advantages Pick up the light in your hand, you can count the number of LEDs and determine its type with proper knowledge. This will allow you to calculate the actual power using the general rules (in the classic "corn", a diode has a power of 0.15 W and a small diode is 0.08 W). High strength-made of plastic. Light weight. Compared with "housekeeper"-no mercury vapor and ultraviolet radiation. The warm-up time is less than one second. The diode is mounted on the entire circumference of the plastic-it cannot be worked at any angle to see all components at once (the lamp will not be dazzling, no protective coating is required). It emits light in all directions without a diffuser. The possibility of repair (classic)-the parts are connected by glue, which is easy to disassemble. In the classic "corn" with COB diodes, heat is dissipated through the metal plate (no need to cool the radiator, thereby reducing product costs). Low power consumption-10 times lower than conventional power consumption and 2 times lower than light-emitting power consumption. Resources exceed 50,000 hours.
Disadvantages of "Corn" The use of a lamp without a frosted bulb violates fire safety regulations. But its presence reduces the brightness by 30-50%. The open circuit arrangement of the contacts is always under voltage (even if it does not matter -12 V). By installation Capacitors can eliminate flicker. At high color temperatures, negative effects on visual equipment are observed.
