The status quo, trends and problems of outdoor advertising lighting (fourth)
The artistic design of advertising lighting requires more than just illuminating, but also beautiful, and artistically attractive. An art work with ingenious artistic design and fine processing, only through the scientific and artistic lighting design, the light source with good color rendering and the light with reasonable light distribution are used to determine the lighting scheme according to the optimal brightness level and brightness distribution. Thus artistically presenting the work to the audience. If the lighting uses light, improper color, or glare, the audience feels uncomfortable, even the excellent advertising works will lose their artistic style, and even become bizarre. Regarding the lighting art of neon advertising, the author has not elaborated on the monographs and a large number of papers. It is worth mentioning that the application of color-changing neon lights will have a profound impact on the art of neon lighting. Because a traditional neon lamp can only emit one color, if you want to change the color of the pattern or text on the neon sign, you have to use multiple neon tubes of different colors in front of the same pattern or text, overlapping and combining. The neon tubes are illuminated by the power control device to achieve the purpose of changing colors. The neon tube thus overlapped and assembled not only has complicated equipment installation, but also has many failure points, poor appearance, and strong pulsation when discolored. The same tube of color-changing neon can produce a variety of different colors, which is undoubtedly beneficial to the illumination of neon signs and logos, and is therefore very popular among users. After examining the color-changing neon signs and decorative lighting used in France, Britain, Hong Kong and Beijing, the author deeply feels that its unique artistic effect is wonderful and worthy of promotion and application. Large billboards are a common medium for public places and traffic, and their lighting is not simply illuminated by lights above or below the billboard. The illuminance and illuminance distribution of the card surface, the optical performance, color effect, installation position of the light source luminaire, the appearance and color of the lamp bracket are not only artistic but also scientific. For example, the International Commission on Illumination (CIE) has strict scientific regulations on the maximum brightness value of advertising signs. For example, the American Outdoor Advertising Association has strict regulations on the size, illumination and illumination uniformity of outdoor billboards, and the installation of light sources, lamps and equipment, etc. according to different advertising contents and locations. In addition, for the lighting of the light box advertisement and the logo, in order to achieve the best artistic effect of the advertisement screen, the brightness of the advertisement screen is also standard, and the light source lamp and the installation method in the light box are designed according to the brightness of the screen. The brightness and uniformity of the light box screen are calculated by the following formula: Uniformity = brightness near the light source / brightness away from the light source portion. The uniformity is 1 and the uniformity is 2 is the tolerable maximum. For most advertising light boxes, the uniformity of 1.3-1.5 can produce satisfactory results. Due to the rapid increase in the number of outdoor lighting advertisements, the energy consumption of advertising lighting has attracted people's attention. California has also issued energy standards for restricting advertising lighting in different lighting areas. 3.3 Large-scale advertising lighting scale Taiwan's "China Times" has described the store advertisements in Osaka, Japan, and their development trends, which are summarized into three characteristics: large-scale, entertaining and eye-catching. The first major feature is surprisingly large. Whether it is a Japanese-style lantern, a Western-style signboard or a doll, it must be bigger than what any city can see. It is represented by the signature “advertising†of the pufferfish (advertising). It is swaying in the air from the beginning to the end, and it is fascinating in the sky. It is impressive. The trend of large-scale, entertaining and eye-catching Japanese advertising signs is also quite representative internationally. The author associates with the "2000 countdown card" logo on the Eiffel Tower seen in Paris, the projection advertisement on the high-rise wall around the German square, and the advertising of the entire wall of a 12-story building in Chiba Prefecture, Japan. The floodlights on the exterior of the Panda Hotel (Yuelai Hotel), the neon signs on Nathan Road and the skyscrapers of Hong Kong Island, the Las Vegas Safari Hotel, Caesars Palace, Arthur Goddess, A large-scale lighting advertisement in front of the Circus Hotel, a large-screen display advertisement of hundreds of square meters on the southeast side of Shanghai People's Square, a large lobster advertisement on the wall of the Shunfeng restaurant on the west side of Beijing, and a giant flexible light box on Tiananmen Square in 1997. ... and so on, all of them are huge, and they are very eye-catching and leave a deep impression. The trend of large-scale advertising and advertising lighting is becoming more and more obvious.
