The power of line lamps ranges from 6W to 96W, which can be said to have a large span. In fact, 6W 12W 18W 24W 36W, which are commonly used by domestic brands, have a large power but are used less. The power division of foreign products is different from that of domestic products.
2. Light source
The line lamp is a low power light source, and the single power below 1W (5050, 3528, 3014, etc.) is almost covered by several brands. When purchasing, we should not only ask which manufacturer the chip is from, but also which manufacturer it is packaged from. The price of chips from the same brand manufacturers and packaging technologies from different manufacturers will also vary a lot. Generally, the level of well-known brands can meet the application requirements. If you have high requirements for color tolerance and color rendering, that's another matter.
Now the design generally requires that the light source of the line lamp not only has color changes, but also has color temperature changes. The more the light source changes, the richer my performance. At present, the RGB color purity of many line lamps is relatively poor, giving the impression that the color is dirty. Students with high color requirements need to pay attention to this.
When it comes to the angle, it is more complicated. In fact, it is the optical system, which is also the standard to measure the technical level of a manufacturer. For manufacturers without pursuit, they can directly purchase appropriate common mode lenses from lens manufacturers at prices ranging from a few cents to a few cents.
The manufacturer who is a little bit of a pursuer has found a lens factory to open a private model. It is just that the angle is different from the public model on the market, and it can also claim to be a professional manufacturer. The angles are symmetrical 12 °, 24 °, 40 °, and 10 ° X 60 °, 15 °, X30 °, etc. How to evaluate the optical system of the line lamp is in place, and the personal evaluation standard depends on the height and uniformity of the light spot projected from the wall. Unfortunately, few manufacturers can do a good job.
When selecting line lamps, we can only make a reference. Sometimes, the projection distance of line lamps is not high enough, not the power is not enough, but the optical lens is not good enough. Please choose the line lamps based on the projection height of the field test.
In the case of removing the technical deficiencies of its own products, the most likely problem is that the installation distance is too close to the object (surface) to be illuminated. It is easy to cause spot aggregation and uneven transition. (20CM-60CM from the object is an ideal projection distance) If the lens is well designed, this problem will not occur.
