LED semiconductor lighting network news has been so short for 5 months, do you still have a fresh look at the exhibits at the Frankfurt Lighting Fair? After reading the exhibition, is there any harvest of what I want?
Watching the exhibition = learning, watching the lively and watching the doorway, it hasn't been a long time since the exhibition time has passed. This article will take you from the perspective of optics and application, and take a look back at some of the amazing lighting fixtures at the Frankfurt Lighting Fair.
What is the long shot of 100 euros? Why is it so expensive? Look at how these European companies such as XAl, Flos and others are working hard in market segments. Where are their advantages? Why are customers willing to buy a small spotlight of more than 100 euros? After reading this article, you will know where the gap is.
Small spotlights and cabinet display lighting
What is a small spotlight?
Small spotlights refer to spotlights with a size of 50mm or less and a luminous flux between 100-1200lm, which are usually used in local lighting and accent lighting.
â–² As can be seen from the picture, the light of the luminaire is almost completely uniform, and the optical principle is the same as that of the stage light. (Source: Indifferent from the DGA booth in Italy)
â–²The same optical system column lamp, the light intensity is relatively high, even but the light intensity distribution has no transition, it is hard, this kind of light spot is commonly called hard spot. (Source: Indifferent from the DGA booth in Italy)
â–² Compared with the previous lamps, the central light intensity of this luminaire is gradually weakened, and the outer edge of the light spot has a transition, which is more in line with the sensory feeling of the eye. This type of light spot is commonly called soft spot. (Source: Indifferent from the XAL booth in Italy)
Such a lamp is about 100-200 euros, why is it so expensive?
Not only because of the good lighting process, but also because of its core part - excellent light distribution!
Next, this luminaire may be familiar to everyone, that is, Flos Running Magnet.
â–²The light has a transition, the track is embedded, and the lamp is installed with a magnet. It can be seen from the picture that the light is very beautiful and the technology is excellent. Mainly used in local lighting.
The characteristics of this luminaire are: variability, easy and flexible matching, linear embedded guide rail, excellent light efficiency. (Source: Indifferent from the FLOS booth in Italy)

â–² Display effect, such a spotlight can flexibly display the three-dimensionality of the exhibited items, and is often used in advanced display places. (Source: Austria XALN)
ã€€ã€€ Reflective cup-type spotlights have more residual light than lens-mounted lamps, but they also have their advantages. The light color is pure and the light intensity is natural.
â–² From the picture, you can see that the lamps are more super-light, but natural and comfortable. (Source: Indifferent from SWAP booth)
ã€€ã€€ Small note: The selling point of the lamps is the process design and lighting of the lamps, not power or energy saving, and is an excellent light expression effect.
â–²The center is very strong, and the light comes out through a long truncated cone (Source: Indifferent from KREON booth in Italy)
Of course, the foreign moon is not necessarily rounder than the domestic one. The light effect in the picture below is not so good.
â–² As can be seen from the picture, the spot is not evenly transitioned. This is actually a family with the above. One reason for this photo is that it is small angle, it is not suitable for too close to see the effect, and the second may be slightly worse.
Long-distance lamps generally have a strong central light intensity, and the center of the close-range lamps generally has a weak light intensity. (distance and application issues)
Artwork lighting case
â–² Small size lamps are more difficult to control light, and are generally used for local lighting in the atmosphere.
This type of luminaire is characterized by a small diameter and the diameter of the luminaire is generally less than 16 cm. The angle is generally narrow and medium.
Case: Flos's FindMe & The running magnet spot tracking small track, which is characterized by good surface finish of the luminaire and excellent light distribution. In particular, spot tracking is a lamp developed by Flos, which is worthy of learning by manufacturers.
â–² Magnetic linear track, the lamps can be flexibly distributed on the track. The seemingly simple application actually requires high process requirements, and the loss is a thousand miles.
Judging from the situation at the exhibition, foreign manufacturers pay great attention to the atmosphere of light application and the practicality of lamps.
â–²The lighting in the space above is mainly from the surface lights, and then the small spotlights are used as supplementary lighting.
Features: miniaturization, fine craftsmanship, precise light control, popularization, specialization, and diversification;
Application: small range of accent lighting, local lighting
Typical manufacturers: XAL, ERCO, ZUMTOBEL, FLOS, etc.
Major markets: museums, retail displays (watches, bags), art displays, etc.
Typical optics and parameters of classic products
What are the optical angles of small spotlights?
It is important to know what kind of optical parameters are used in different cases and what kind of effects will occur.
SPOT: The beam angle is 16Â°, which is used for long-distance display, generally between 1.5m and 2.5m.
MEDIUM: The beam angle is 24-28Â°, which is used for medium and long distance display, generally between 0.7m and 1.8m.
FLOOD: The beam angle is 28Â°, which is used for short distance display, generally between 0.4m and 0.8m.
FLOS's FindMe luminaire series parameters:
Why do you need special display lighting?
Because the human eye is a horizontal viewing angle of 180Â° & a vertical viewing angle of 150Â°, the visual acuity of the human eye is limited to 1-2Â°. Therefore, how to attract people's attention to the exhibits or shelves is to show the purpose of lighting.
â–² accent lighting can capture people's attention
to sum up:
Small spotlights are often used for accent lighting and local lighting in order to capture the human eye;
The main optical angles are: 15Â°, 25Â°, 35Â°, polarized light;
The main features of the luminaire are: fine workmanship, precise light distribution and pure light color.
Why is Flos's spotlights so expensive to sell? The reason, in addition to excellent process technology, the most important thing is the light distribution of the lamps.
Domestic manufacturers have done a very good job in the level of process technology, but there is still a gap between the optical technology of the lamps and the foreign manufacturers. If you want to improve the optical quality of the lamps, there is still a long way to go.
