LED luminaire design: from the outer garment to the infiltration of the connotation

[Source: "Engineering LED- lighting market," 12 issue of reporter / Zhou Jianhua]

It is understood that the German iF Design Award was founded in 1954 by the Hannover Industrial Design Forum in Germany, and is one of the most respected annual awards in the industrial design industry. Its evaluation criteria include product attributes such as aesthetics, product quality, material selection, technological innovation, and functionality, as well as clear indicators of user experience attributes such as ergonomics, safety, environmental protection, and durability. In the tube, the LED lighting design has not only stayed in the appearance but also extended to the overall connotation of light efficiency, heat dissipation and system. Tang Shiquan, chairman of Tangshi Lighting, also has unique insights and hopes to share with the industry.

"Lighting Market" : With the continuous improvement of LED manufacturing process, the appearance of LED lighting is more abundant and free. Do you think LED lighting design has become the main performance of domestic and foreign famous brands to form differential competitiveness?

Tang Shiquan : The development of LED technology has made the shape of decorative lamps more varied. Many amazing designs are realized by the characteristics of LEDs. The avant-garde shape really helps the product differentiation competition.

For LED commercial lighting products, the shape of the lamp is actually only an important part of industrial aesthetics. The integration ability hidden in the shape is the real competitive advantage of the product. Similarly, to achieve the goal of brand differentiation competition, you can't just look at the product, but ignore other links beyond the product. Based on the core concept of the brand, it is the most important to find the right direction and the right product to serve the market.

"Lighting Market" : How many LED companies have participated in the German iF Design Award this year? What are the main products to participate in? What are the core strengths of the award-winning DW-409R recessed lamp?

Tang Shiquan : Among the award-winning products this year, the number of products incorporating LED elements in the design is much higher than in previous years. Among them, the products that focus on lighting functions gradually extend the design points from the product shape to the performance direction.

In the cooperation with architects and lighting designers, we have a deeper understanding of the emotional appeal of space. Good design ideas often come from customer needs, and spatial structure is the architect's response to this need. When the customer feels the fit between space and their own needs, it gives the space an emotion, a story, and the excellent light is telling the story for the space.

The DW-409R recessed lamp is diverging around the function of the wall washer. It adheres to the consistent fine aesthetics of Tang Shi, and incorporates the oriental elements of the "black silk cap" into the shape. Although the shape is small, it uses 9 LED lighting chips to achieve super High luminaire efficiency, can be rotated 355 ° in the horizontal direction, and can also swing 45 ° downward, to meet the lighting needs of the wall or painting.

"Lighting Market" : Many people think that lighting design is the design. Do you agree with this view? In addition to the design, what elements do you think the true LED luminaire design should contain?

Tang Shiquan : As far as the lighting industry is concerned, I am not opposed to this point of view. After all, the appearance determines the customer's first impression of product perception, but from the point of view of the market segment, there is room for further discussion on this issue.

Take Tangshi as an example, we focus on the field of commercial lighting. Business is to serve people. This kind of application environment determines that customers and goods are the protagonists in space. Lighting should reflect respect for people and space environment. Similarly, the essence of lighting lies in lighting. Lamps are only the carrier of lights, except for The simple and neat shape keeps the overall appearance of the space. The higher light efficiency, the more beautiful light shape and the more comfortable lighting experience are the most important and most overlooked parts hidden in the design of the luminaire.

"Lighting Market ": Why does the award-winning luminaire have a special meaning in the design of the "Song Dynasty official hat"? In terms of heat dissipation structure, illumination and light efficiency, what are the technical advantages?

Tang Shiquan : For the world, the oriental elements carry an ancient, mysterious temperament. "Humble" in Confucianism is a realm that contains the meaning of respect, and "respect for the environment and respect for the designer" is the core concept of the product design of the soup. As a wall washer, the large-angle swing design is one of the essential elements, and the installation position on the ceiling is usually closer to the wall. The light body after the pull-down is just like the center of the space, just like the ancient minister to the monarch bow. Around this "modest" image, and then through the tempering of industrial aesthetics, the combination of oriental culture and fashion technology has finally produced this series of products.

With its keen market insight, Tangshi has developed LED lamps at the end of 2004, and continues to innovate with the advancement of technology to create an elegant light shape with high luminous efficiency, low energy consumption and long life. Today, the design module used by Tangshi's LED luminaires is already the third generation design of the Tangshi Group. It not only has a more compact structure, but also maintains a higher level of light efficiency and longevity through an integrated design. Taking the DW-409R as an example, the small size accommodates 9 high-efficiency lighting special chips, including the driver's overall energy consumption is only 12W, but the light intensity is comparable to the 50W halogen lamp at the same angle. The excellent temperature control design makes the life of the LED chip still more than 70% of the initial luminous flux after 50,000 hours of use. Not only the color temperature drift is controlled to a very small range, but also the color shift situation is avoided to the utmost extent. Among the products like light efficiency and energy consumption, the DW-409R is the smallest.
