Editor's note: Since the birth of LED lighting, people have paid more attention to its practical value. The author of this article has crossed this limitation and placed the higher value of the longer-term value of art value on LED lighting.
Summary:
As a semiconductor lighting LED, it has developed rapidly since its birth. The improvement of the lighting performance of LED light sources has led to an increase in the discussion of its application value. This paper discusses the value of this kind of lighting in the art field from the characteristics and predictable prospects of the LED light source itself.

introduction
Traditional lighting sources have undergone two leapfrogs. For the first time, people have shifted from using natural light sources to using electric light sources. On the surface, we have replaced the flames with the electric light source that we call incandescent lamps. Leap is the birth of fluorescent lamps, which is the birth of photoluminescence technology. Nowadays, the LEDs that have just been developed since the 1990s are not only close to the performance of the traditional lighting sources of the former two in terms of light color performance, but also have many unique advantages. However, this article does not discuss LED as an advanced lighting technology in the field of lighting alternative to traditional light sources, but on the technical performance of LED itself, to discuss the artistic value of LED lighting, and even more unique advantages.
From today's lighting LEDs, the main products are LED parallel development of RGB hybrid and blue-emitting phosphors. In fact, these two ways of lighting LEDs have their own advantages in different directions, and lighting is not limited to the application of white light, especially in the art field.
Starting from the concept of lighting itself, according to Richard Kelly's theory, we use three basic functions of lighting to explore the characteristics of LED lighting in the field of art. Its three basic functions are introduced as follows:
(1) Ambient light - providing background lighting
(2) focal glow - providing local, focused lighting
(3) Play of brilliance - providing information about the light source itself
Art and lighting
Art itself has existed since the birth of human beings. The images of human beings, emotions, and wills are mutually influenced by expression and contact. Art, as a manifestation of the innate creativity of human beings, is an important medium and way for one to express and influence each other. In the meantime, we know that the conveyance of artistic information is often realized through the senses of sight, hearing, touch, etc., and as an ordinary person, more than 70% of the information received is done visually. Therefore, for the expression of light color information, lighting is particularly important. Here are a few representative art categories to discuss.
The most direct thing is art. There is no need to question the requirements of light and color in the painting class. Whether it is Ambient light or focal glow, it is necessary to have sufficient illumination performance and high color rendering. At this point, sufficient illumination makes the light intensity reflected from the surface of the painting into the eye sufficiently stimulating that it is clearly distinguishable. At the same time, the high color rendering of the light source allows the author to use the color to the maximum extent. Whether in an art gallery or a studio, the needs are the same.
The same is true for sculpture, and the combination of proper light and shadow enables the three-dimensionality of the sculpture to be realized. This requirement for the focal glow will be higher. After all, focal glow provides a unique way of lighting. More than just illuminance and color rendering, the luminaire must provide the proper beam distribution for the purpose.
In the traditional sense, architectural lighting is mainly the use of ambient light Ambient light. Providing an environment that satisfies production and life, ambient light is especially important. However, modern architectural art is no longer limited to just the need for ambient light. It can be said that architectural art and lighting art have been integrated to a considerable extent, or that the latter has been absorbed by the former and become a bright spot in modern architecture. As the night scene of the emerging projects of modern urban construction, it is the partial expression of this art; not only the traditional lineage of ambient light, but also a great play in the two functions of focus light and brilliant performance - from a large area Floodlighting luminaires, to the key lighting fixtures with narrow beam angles, can be seen to highlight the characteristics of the light source information and strip light sources. Whether it is explained that night lighting is the value of lighting technology in architectural art, or that architectural art has produced a new art form due to night lighting, it can be seen that lighting technology is unique in the field of architecture. charm.
In the field of music and drama, the value of lighting is not small. The needs of the concert hall and the room for the background light should satisfy the artist or musician to read and play. However, the lighting in a good auditorium should also create an atmosphere, not just to meet the illumination requirements. Then, in the traditional classical atmosphere, the white light of the appropriate color temperature will determine the tone of the whole scene; in the face of modern or popular music, the role of the light is even greater - the various lights, screens and so on. In this case, the art of lighting is vividly displayed by the play of brilliance, because such an occasion does not require the lighting capability of the luminaire, and the information that the light itself brings out - different The combination of beam angle, hue and direction is an artistic carrier.
In addition, the lamp itself can also be used as a work of art. Because the body of the luminaire is very malleable in appearance. The three-dimensional construction can take the form of sculpture. What is more valuable is that the brilliant performance of lighting greatly increases the imagination of this art form, because such art works not only has physical expression, but also emits various kinds of light - to express the author's thoughts. Then, this kind of artistic entity is not only tangible and qualitative, but also the infinite light.
