When humans know how to add a cover to a light source, it means starting an attempt to control the light. Therefore, functional lights such as street lights and table lamps with strict directionality appear. With the development of technology, the light source has a smaller volume, and there are lamps that have a better angle of light and better control. That is a spotlight.
Therefore, in functional luminaires, whether the scope of the application of the spotlight or the depth of the technology development is undoubtedly can be called extremely representative.
Therefore, if you want to learn efficiently through the glimpse of the leopard, how to choose a good functional luminaire, it is best to choose a representative to report.
This article tells everyone how to optimistic about LED spotlights:
a look at the spot
Maybe you have a problem when you look at this "look at first": Most of the methods of selecting products are to look at the appearance first, why do you want to put the spot first?
Good question, because for functional luminaires, "function" is always in the first place, the quality of "light" is its "appearance", so even if you make the function luminaire so good, it will come out The quality of the light is not good, this is also a defective product.
The shape of the spot as the light of the spotlight projected on the plane is the first standard line for judging the light quality of the lamp.
The excellent light spot directly improves the excellent visual experience of the item, the point of appeal is clear, and the extension of the light is more natural:
a: The reflector is evenly distributed, the center strength is gradually weakened outward, and the halo is naturally comfortable. This is a practical and comprehensive spot effect;
b: uneven light distribution, serious dark spots in dark spots, low light utilization rate, poor performance of the articles being photographed;
c: multiple shadows on the halo boundary, the spots are rigid, and the ghosts and ghosts are obvious.
Figure: Different types of spots, different angles of illumination. The good spot is sharply focused, the image is even, and the surrounding light naturally spreads, without stray light and dark spots.
Figure: The structure and color of the illuminated surface or object are relatively complicated (for example, the left-hand clothing store hanging plate display), the appearance of the spot is not too clean and not too particular, and can not be seen. However, if the illuminated surface or item is simple and clean (for example, the museum on the right), if the spot is not clean enough, it is easy to expose. Therefore, since the directionality of the light of the spotlight is clear and is mostly used for accent lighting, the different quality of the spot determines the range in which it is used.
