How to choose a line light? Look at these 4 is enough!

In this issue, talk about the line lights , then talk about ten dollars.

The definition of line lights is quite broad, as long as the line-type lamps seem to be called line lights. Just like Guangdong, it is a girl who can call a prostitute. A man can call a boss, even if you come to eat bowls! There were a few times when someone called me a cicada. I just didn’t respond. I was calling me. When I reacted and called me, I was stunned in my heart, and then I was very serious about telling myself that this was awkward. . .

Why do you want to tune the line lights, because the line lights are the most widely used and most widely used products in lighting design, which is very representative. But how to distinguish the advantages and disadvantages of the line lights, this needs to be a little learned.

Below I will give you a brief introduction from the perspective of power source and application. Clear mind, industry veterans bypass.

power

Line lamp power from 6W —96W can be said that the span is relatively large, in fact, domestic brands are generally used 6W 12W 18W 24W 36W power is large but relatively small. There is still a difference between the power distribution of foreign products and the domestic ones.

▲Germany traxon RGBW 85W IP66

▲Germany traxon Nano Liner Allegro AC XB 50W IP66 

▲ Philips colorkinetics iW series from 28W IP66

▲ Philips colorkinetics ColorGraze MX4 series 74W IP66

▲Italy iguzzini Led Tube 10W IP67

▲Italy iguzzini Linealuce surface 32W IP66

I will not let go of the products of domestic manufacturers, and the appearance is similar. Anyway, I haven’t seen the line lights of the domestic manufacturer that can make my eyes shine. They are all standing on the pigs. Nobody can say who is ugly.

light source

The line lamp is a low-power light source. The single power below 1W (5050 3528 3014, etc.) is almost monopolized by the domestic brand. The foreigner simply does not match the domestic light source brand, but simply does not focus on the small power chip. . In addition to asking which manufacturer’s chip is in the procurement, it is also necessary to ask which factory is packaged. The chip of the same brand manufacturer, the packaging technology of different manufacturers, the price will be quite different. Generally, the level of domestic famous brands can meet the application requirements. If you have high requirements on color tolerance and color rendering, then it is another matter.

The high-power light source foreign brands are still dominant. Since the introduction of Osram’s 3030 single 1W lines, the market for line lights has been quickly occupied. The price of big brands is still cheap, it is simply the price of cabbage. Other foreign brands can only follow the trend. RGBW chips will slowly become mainstream. In the near future, it is possible that the six-in-one chip will also extend from the stage light application to the line light field.

I now design to generally require the line light source to change color temperature in addition to color changes. The more the light source changes, the more my performance is. At present, the color purity of domestic line lights RGB is relatively poor, giving people a feeling that the color is dirty. Students who have high color requirements need to pay attention to this.

angle

Speaking of the angle is more complicated, in fact, is the optical system, which is also a standard to measure the technical level of a manufacturer.Manufacturers who have not pursued, buy a suitable male model lens directly from the lens factory, the price varies from a few points to a few degrees.

A little sought after manufacturers, looking for a lens factory to open a private model, nothing more than the market is different from the public model, but also can claim to be a professional manufacturer. The angle is symmetrical 12 degrees 24 degrees 40 degrees, etc., and the asymmetric elliptical spot is 10 ° X 60 ° 15 ° X 30 ° and so on. How to evaluate the optical system of the line lamp in place, personal evaluation criteria, it depends on the height and uniformity of the spot projected by the wall. It is a pity that there are very few manufacturers that can do well in China.

▲ 5050 line light 120 ° wide angle, it is recommended to project a distance of 1 meter high

▲Narrow-angle high-power line lights, there are not many domestic manufacturers that can project such high distances.

▲ Medium-angle high-power line lights, the wall washing range is indicated.

▲ Ellipse mid-angle high-power line lights, the wall washing range is indicated.

The above four projection distance diagrams are the standard diagrams of a foreign manufacturer. When selecting a line fixture, it can only be used as a reference. Sometimes the distance of the line fixture is not high enough, not the power is not enough, and the optical lens is often not done well. When you choose a line fixture, please refer to the projection height of the field test.

▲The ideal line lamp washes the wall.

▲ Unsatisfactory wall washers, the light is almost impossible. Such lamps have a high market share.

application

In the case of the lack of technical skills of the line lamp, the most common problem is that the installation distance is too close to the object being illuminated. It is easy to cause spot gathering and uneven transition. (The distance from the object is 20CM-60CM is the ideal projection distance.) If the lens is designed well, this problem will not occur.

▲The reverse case, the photo comes from Baidu pictures, in fact, I want to know who these golden products are sold to. . .

The following photo of the wall washer case is worthy of promotion.

The above picture of architectural lighting is the perfect example of the combination of line lights and spotlights I have seen.

I have written so much without my mind, I can’t write it anymore. Just want to say, your perfect lighting design, don’t destroy the online light, not every linear light can be called line wall washer.
