How to choose a freezer light

Posted on

The application of led is more and more extensive, and as the refrigerator lighting is a very large market, the refrigerator lighting has its differences with other lighting, then should the lighting buy LED freezer lights?
Freezer light
There are three factors to consider in refrigerator lighting:
1. Safety, the freezer is generally placed in the mall to sell the products for sale, any purchaser can access, all the electricity used in the freezer, including lighting, need to be insulated.
2. Space, the space of the freezer itself is not large. Due to the high space cost, most places are used. Even the place where the lighting products are installed is very limited, so the volume of the lamp is very important.
3. Waterproof performance, in order to ensure the freshness of the product, the temperature of the freezer is generally around minus 20 degrees. Because the temperature is too low, the moisture is too heavy, and a lot of water droplets will be generated. However, because the space for installing the lamp is too small, there is no way to The lamp tube is covered with a protective layer, so the protection level of the lamp tube must be IP66 at the minimum, in order to achieve the intrusion of the water tube for a long time, and to ensure the normal illumination of the lamp tube.

Zener Diode, the English name Zener diode, also known as Zener diode. By using the reverse breakdown state of the pn junction, the current can be varied over a wide range and the voltage is substantially constant, and the diode that acts as a voltage regulator is fabricated. [1] This diode is a semiconductor device that has a very high resistance until the critical reverse breakdown voltage. At this critical breakdown point, the reverse resistance is reduced to a small value in this low resistance region. The current is increased and the voltage is kept constant. The Zener diode is binned according to the breakdown voltage. Because of this characteristic, the Zener diode is mainly used as a voltage regulator or voltage reference component. Zener diodes can be connected in series for use at higher voltages, resulting in higher regulated voltages in series.
