As a new type of energy-saving light source, LED wall washer has been widely used in outdoor landscape lighting. It is energy-saving and has a long service life. It has been favored by consumers, but how many consumers really understand LED wall washers. What about buying?
Nowadays, there are many kinds of led wall washers on the market, and the styles are novel. However, customers are getting more and more difficult in choosing. What kind of wall washers are better? How do new people buy LED wall washers and need to pay attention to them? What?
Before buying LED wall washers , first understand which parts of LED wall washers are mainly composed! In fact, we only need to understand some of the elements that LED wall washers pay attention to when purchasing. I believe that when you choose products, you have certain help.
First of all, we must pay careful attention to the power of the LED wall washer, because its power is directly related to the projection distance of the lamp. The power on the market today is mainly 20 watts, 36 watts, 48 ​​watts, etc., but These powers are not absolute. We can adjust the rated power of the wall washer according to our actual situation. If we want to use some high-power wall washers, we need to use single row, and multiple rows are generally Use less power.
The voltage of the LED wall washer is also an aspect that we need to pay attention to. Its power supply can be divided into DC power supply and AC power supply. If it is a built-in power supply, we need to install AC power, and the voltage of the AC power supply is also generally It is within a few tens of volts, and the specific situation depends on the different manufacturers of the wall washers. Because different producers, the voltage produced will be different.
The heat dissipation of the LED wall washer is very important, and the heat dissipation efficiency judgment method.
Generally, there are users or dealers who do not have a thermometer at hand. The energy absorption can be judged by the hand feeling. The ambient temperature varies according to the season. In the same day, the test will have different temperatures. Only the temperature rise of the lamp is almost unchanged. It can test the heat dissipation effect of LED lamps, judge the heat dissipation effect of LED lamps with the temperature rise of the lamps, and illuminate the two LED lamps with the same heat dissipation structure at the same time, which lamp reaches the highest temperature first, then the heat dissipation of the lamp is compared Well, that is, the thermal resistance of the light source and the heat sink is small, and the above three points can basically select the LED lamps of really good quality!
