The LED lamps generally used in outdoor lighting projects include LED light strips, LED wall washers, LED projection lights, LED guardrail tubes, and LED line light sources. Among them, LED light strips and LED guardrail tubes are mainly used to describe the outline of the building or form a dynamic display screen, while the outdoor lighting project is mainly to directly illuminate the exterior wall of the building. LED projection lights are used to illuminate the column caps or top parts of buildings. Its direct beam aspect ratio is relatively high, but the lighting width range is very close. LED line light source mainly plays a decorative lighting effect on buildings. Many buildings choose to install a linear light source on each floor for decoration. But there is another function that is used to make a dynamic dot matrix screen.
In the past when our lighting was basically white woven lights, if the color temperature difference between the light sources was 150K, we could judge the color difference between them with our eyes, but the color temperature difference between the current LED era and the previous white woven color temperature Timing makes a big difference.
I believe everyone has a certain understanding of the technical term “color temperature”. Color temperature is actually heating the black body to a temperature point. When the color of the light emitted by it is the same as the color emitted by the light source, the heating temperature of the black body is called the color temperature, usually called: color temperature.
Apparently a color that can be distinguished by the naked eye, how come the data values are somewhat different instead of much? Here is an explanation of this lighting parameter: Correlated Color Temperature.
You should be able to see the data in the test. It’s the relative color temperature, not the color temperature. Is there a difference between them? Of course there is. Color temperature means: at a certain temperature, when the color of the light emitted by the light source is the same as that of the black body, the temperature of the black body is called the color temperature of the light source. In other words, it can only be called color temperature when it falls on the black body radiation line.
The light emitted by outdoor lighting fixtures is not thermal radiation, so its light color may not fall on the black body radiation line, then we can only find points close to the line, and there is a correlation with the color temperature.
When we receive the outdoor lighting project, we must first make a lighting design rendering for the building design plan, and let the customer clarify the design rendering. After the customer is satisfied, we select the appropriate LED lighting lamps according to the design renderings, and then calculate the actual number of lamps according to the CAD engineering drawings of the engineering building, and we select the power transformer and control board according to the actual number. It must be noted that if there are LED projection lights and outdoor lighting projects, you must first look at the actual height of the lamps on the design renderings, and we will select lamps and lanterns based on this. output power size. Due to the degree of myopia of different lenses and different power, the aspect ratio of the direct light is different. Therefore, when you propose to receive a new project, you must choose a professional, experienced and reliable outdoor lighting engineering manufacturer.
