Advantages of LED Lights in Cold Areas

In recent years, LED technology has started to mature. The segmentation of LED lights continues to deepen and evolve.
segmentation; It is a method that aims to create a strategy for the small market selected from these sections by dividing the market in which the brands or companies are concerned. Today, the market demand of LED lights is increasing significantly by individuals and companies.

Compared to incandescent, fluorescent and HID, the electronics of LED lights work much better at normal temperatures. The lighting effect and lighting effects of LEDs perform much better in cities or countries with warm seasons. This is a disadvantage for cities that are cold, but these problems are improved with the R&D studies carried out by lighting product suppliers against them.

LED components have many advantages in cold environments. Factors that affect the illumination output of LED lights include driving power, housing material, airborne fog ratio, strong sunlight, and other comprehensive weather factors. These factors can cause difficulties and problems in the implementation of LED street lights. Solutions can be found for some of these factors, but the durability of the LEDs becomes very important when it comes to rain, snow, storm.

Starting the drive power at low temperatures is a problem. This is mainly because most of the current driving forces are inseparable from the wide application of electrolytic capacitors. In fact, the electrolyte activity of the electrolytic capacitor is significantly reduced, and the capacitor's capacitance is greatly weakened in a low temperature environment such as minus 25, causing the circuit to not work properly. The solution to this is to use a high quality capacitor with a wider operating temperature range and this increases the cost considerably. The second solution is to use drive power without electrolytic capacitor circuit design, including the use of ceramic laminated capacitor, linear drive and other drive schemes.

It is known that the brittleness of plastic and rubber materials increases after a certain degree. These materials are also generally used in the visors, optical lenses, gaskets and other components of outdoor LED lighting. If these materials are used, special attention should be paid to the load-bearing parts and the parts should be as strong as possible. Breakage or damage to LED lights can be prevented at low temperatures, especially in situations such as wind and storm.

LED lights generally adopt the harmonious structure of plastic parts and metal. There is a significant difference in the coefficient of expansion between these two materials when the temperature changes greatly. This is also one of the main reasons why the outdoor LED light waterproof fails. For example, the expansion coefficient of commonly used plastic materials is about 5 times that of commonly used aluminum. Because of this difference, structural components are often prone to voids or even cracking of the plastic material. This results in poor waterproofing and problems with the product. Especially in cold cities, when the luminaires are lit, the temperature in the luminaires suddenly evolves from cold to hot with the heat produced by the lights, which can lead to cracks and waterproofing failure.

In many places the fog gradually increases with the coming of winter. In places where the weather is foggy, not only should the CRI (Color Rendering Index) level be taken into account in the selection and use of LED light, but also the ability of the light to penetrate the fog and the harmony between the light and the environment.

You should choose high quality LED lights that will benefit you for long periods of time in terms of high efficiency, durability and performance.
