With the opening of the famous Italian lighting design and manufacturing brand Flos in Beijing, the concept of customized lamps will soon appear in the Chinese market.
For designers, especially interior designers, choosing lamps is a headache for them. Because there are so many Chinese lighting brands, the quality, style and shape are so different that their understanding of Chinese lighting products is very confusing. When choosing a luminaire, it often encounters a situation where the luminaire product is far from the actual design idea, and thus the market demand for luminaire customization is derived. Then, in the actual design, what is the status of lighting customization requirements? How do designers solve such problems? What are their expectations for lighting manufacturers? How do lighting companies view this problem?
In order to solve the above doubts, several designers exchanged views and opinions with Mr. Zhou Zhaopeng, Foshan Lighting Engineering Project Manager.

Xu Qinghui: There is a big difference between the attitudes of lighting manufacturers and small factories.
When doing the project, some lighting companies provide products that do not fully meet my lighting design needs. This is also the case. Therefore, I often give the lighting manufacturer some opinions and opinions on the lighting fixtures from the perspective of lighting designers according to their own needs. Of course, many times, those big domestic manufacturers usually don't accept my suggestion, and they won't easily change their products. However, other small manufacturers are more willing to accept my opinion, and can quickly make new products based on our opinions. In my opinion, as long as their products are of good quality, especially in terms of light distribution, I will also recognize their products and have confidence in their future good lighting products.
Wang Peixing: Customization issues require designers and lighting companies to trust each other
I have encountered a situation where the product does not match the needs and needs to be re-modified by the enterprise. We do relatively outdoor lighting, and there are many LED lamps used, and most of the LEDs are now fixed products, which often occurs.
The solution depends on the sincerity of both parties. If the manufacturer can take this responsibility and revise it, then continue to cooperate. Or it is our responsibility, we will pay a certain fee appropriately; if the manufacturer is sophistry, then the contract is terminated, and then find another. In order to avoid this situation as much as possible, we will go to the factory to see the structure, and then do small batch samples, then go to the field to test the lights, let the owners approve, and finally mass production. In this way, operating costs and product errors are much lower.
We hope that manufacturers can communicate with engineering companies and designers as much as possible and fully trust each other.
Weng Miaoyan: Customized quantity determines corporate attitude
Sometimes there are situations where special custom luminaires are required during the design process. Under normal circumstances, we are directly communicating with the manufacturer, and we will explain our needs to the manufacturer. In contrast, manufacturers are more willing to accept non-customized product orders. There are many factors limiting customization, such as quantity, effect, and so on. If the number of custom lamps is large, the attitude of the manufacturer is OK, and it is more willing to cooperate. If the designer has very few custom lamps, the manufacturer may simply reject the order.
Chen Haiyan: Domestic manufacturers are generally willing to cooperate with the modification
In the design process, the situation that the lighting products are inconsistent and needs to be re-modified by the enterprise has been encountered. The proportion of luminaires that need to be re-modified varies from project to project type, but as people's demand for individuality increases, this custom-made situation has a growing trend.
In this case, the general solution is to find a production company to cooperate with. In general, domestic manufacturers are very active. When we exchange custom information with manufacturers, we often encounter communication obstacles. This requires manufacturers to improve their own lighting professional skills. Some manufacturers may have a lack of professionalism, and communication is not very technical. Unblocked.
Liu Runze: Lighting business supporting services need to be improved
This situation is more common in design and construction, I think this is normal, because people's needs are constantly changing.
If the manufacturer has the right product, we will directly find the manufacturer to transfer the goods, otherwise we will find another way. The price of customized products is relatively high, and the profits of lighting companies are relatively high. Therefore, the suppliers we cooperate with are more willing to accept custom orders. As a designer, I am satisfied with the customized products made by lighting companies. The fly in the ointment is that sometimes the customized final product does not necessarily meet the requirements of the designer. Some supporting services cannot be kept up in the enterprise. This is also the place where lighting companies should improve in the future.
From the designer's point of view, I hope that manufacturers can seize the market to understand the dynamics, predict in advance, and reserve resources.
Zhang Xuequn: Lighting product customization is not a problem
I have encountered a custom product because the designer sometimes needs some special products after all. Our solution is to look for products directly. In the course of our design and construction, there are many cases where special customized products are needed. The current lighting market products are very comprehensive in appearance and type. There are many products to choose from, and the shape is not a problem at all. Therefore, if you can't find a suitable one at home, you can change one.
Shao Bin: Contract effect is easy to solve custom problems
I have encountered a situation where the product does not meet the needs, but the number is small and is not often encountered. As for the solution, we are all re-delivering or modifying the manufacturer. Under normal circumstances, we signed a contract with the manufacturer, the manufacturers will actively cooperate, but the attitude can only be said in general. If the designer or engineering company does not sign a contract with the manufacturer, it may be more difficult to operate.
Our requirement for the production enterprise is that they can produce the lamps in strict accordance with the requirements of our ordering, and try to avoid the occurrence of the product being inconsistent with the application and then being re-modified.
Shao Tian: Looking for a more suitable product until Party A is satisfied
In the process of design, it is of course possible that the lighting company's products will not meet the lighting design requirements. At this time, we generally continue to look for more suitable products until Party A is satisfied.
Generally speaking, as a lighting designer, to push a lighting product to Party A, it must be a product that you know very well. Under such circumstances, if Party A has seen the product and feels satisfied, the lighting product meets the design requirements, and of course, there is no problem in the final installation and use. If the products we recommend cannot be satisfied by Party A, then according to Party A's price and requirements, help him find lighting products that can meet the relevant conditions. Therefore, the lighting products that were finally decided to be used are selected by everyone and are suitable lighting products that can meet the relevant requirements.
Liu Xiaofeng: Two-way communication between designers and lighting companies to complete customization
In the process of interior design, there were customers who offered to customize lighting products. However, there are not many such cases. Only one or two of the 20 customers have this demand. There are also lighting products that I can't find suitable for the decorative environment, and the appearance needs to be re-modified or even innovative.
Under normal circumstances, if the customer asks for customization, as a designer, after listening to the customer's design requirements, I will present my professional advice and design ideas, and draw the appearance of the lighting after the customer accepts it. Next, on behalf of the customer, I communicate with the lighting supplier. The other party will give professional advice on the lighting process and lighting requirements, and finally combine the design of my appearance to make customized products. In the urban people of Beijing, the lighting supplier we cooperate with is NVC Lighting. We cooperate very well and the channels are mature.
Yu Xiaowei: 70% of the lamps need to be customized
About 70% of the lamps we use are custom-made. Most of the hotel's decorative lighting is that we draw the design according to different design styles and cultural orientations, and then find the manufacturers to customize. Ambient lighting is a combination of mature products.
As for whether the manufacturer is willing to accept customization, it depends on the manufacturer's own business ideas. If the company is not willing to customize, we will find other manufacturers, there is no problem.
Li Shenghui: Whose products are better, who are we looking for?
We generally cooperate with manufacturers. We will tell manufacturers what types of lamps are needed and then let them provide them. Moreover, such manufacturers are not fixed. There will be many manufacturers to apply, just like bidding.
We give specific technical parameters, and whose products meet such requirements, we choose who to cooperate with, provided that the service and quality of the products are guaranteed. Our engineering projects are basically carried out in this way, without a fixed cooperative enterprise.
The structure of the building is different, and the demand for the lamps is different. We definitely hope that there are good lamps with good lighting design. For the cooperation matters, we usually set our own, and then the manufacturers will help us, but for the professional issues of heat dissipation, waterproof, etc., we need the opinions and guidance of the manufacturers. In short, each project has different requirements for lighting, and the requirements of our inspection manufacturers are different.
Enterprise: Safety Customization Reduces Waste Foshan Lighting for Product Customization
Referring to the customization problem, Zhou Zhaopeng, the project manager of Foshan Lighting Project, said that due to the short-term start of domestic lighting, no matter the difference in workmanship, materials, functions, creativity and other foreign lamps, some large-scale engineering projects in China are basically When foreign designers design, they use a large number of foreign lighting styling and light distribution. In this case, the owners require more customization. Zhou Zhaopeng said: Foshan Lighting has more customizations in engineering export lighting products, and engineering, especially in large museums, due to the different characteristics of the exhibited products, the pavilion has different requirements for the light environment, and the lighting also has different requirements for the environment. The temperature has high requirements, so the customization problem is that our lighting products are not rich enough, and there is not enough lighting design and manufacturing for some special lighting.
At the same time, Zhou Zhaopeng also stressed that when a custom problem occurs, Foshan Lighting will strictly follow the principles of safety, practicability and aesthetics, and communicate with Party A on the premise of adhering to this principle, including heat dissipation and light distribution of lamps. . If Party A insists on the unique style of the lamp and neglects the safety of the lamp, Foshan Lighting has to give up the project.
As for the designer's requirements for the style of the lamps, Zhou Zhaopeng pointed out that most designers currently choose the lamps in a general category, and the current types of lamps are only crystal lamps, craft lamps, etc. Other lamps, such as brackets, downlights, and grille lamps, generally have good light distribution effects and exquisite energy saving. However, Zhou Zhaopeng believes that no matter how the shape of the luminaire changes, a luminaire, regardless of its shape and size, has different functional structures, and has the following basic components:
1, the outer shell
It is used to install various parts inside the lamp, and to support and fix the carrier of the lamp itself. The shell material can be made of metal materials such as iron or aluminum or plastic according to requirements and use environment.
2, electrical components
Including ballasts, starters, lamp holders, wires, terminals, etc. For different types of luminaires, the electrical components used vary. The basic requirements for each component are briefly described below:
A) Ballast: A device that combines inductors, capacitors, or resistors, either individually or in combination, between a power source and one or more discharge lamps to limit the lamp current to the desired value. The ballast is a key component of the ignition point of a gas discharge lamp and is also the heart of a lamp.
According to the different light sources, there are fluorescent lamp ballasts, metal halide lamp ballasts, high pressure sodium lamp ballasts, and the like. Fluorescent lamp ballasts are also inductive and electronic. In recent years, some high-intensity gas discharge lamps have also developed electronic ballasts.
B) Lamp holder: It is a component that fixes the light source and conducts current. The lamp holders of fluorescent lamps are generally made of plastic lamp holders. According to the basic safety requirements of national standards, they are flame retardant and heat resistant to 125 °C.
The lamp holder of the high-intensity discharge lamp lamp generally adopts a ceramic lamp holder to adapt to the working environment under high temperature.
C) wire
The wires are divided into internal wiring and external wiring.
Internal wiring refers to the wiring inside the luminaire and attached to the luminaire for connecting the lamp holder, wiring, terminals and ballast; external wiring refers to the wiring outside the luminaire and attached to the luminaire, the external wiring is used to illuminate the luminaire Connect to a power source or an external ballast.
Wire requirements for internal wiring:
When the normal working current of the luminaire is higher than 2A, the nominal cross-sectional area of ​​the electric wire is at least 0.5mm2, and the nominal thickness of the insulating layer is at least 0.6mm.
The normal operating current of the luminaire is less than 2A. In the case of mechanically protected wiring, the nominal cross-sectional area of ​​the electric wire is at least 0.4mm2, and the nominal thickness of the insulating layer is at least 0.5mm.
External wiring: The nominal cross-sectional area of ​​the external wiring conductor of ordinary lamps is not less than 0.75mm2.
D) Terminal block
The components used to make electrical connections to the conductors are available in both threaded and unthreaded terminals. Threaded terminals are commonly used in common luminaires.
Zhou Zhaopeng said that there are two aspects of waste in the customization of lighting fixtures. One is the waste of developing molds due to the excessive pursuit of individualized styles, because many unique styles of molds can not be reused and can only be used for this project. After the project is over, many materials will become a pile of scrap copper scrap, causing a certain amount of waste. Another aspect is the waste of light efficiency due to the lack of attention to the scientific design of the shape. This aspect of waste is more common in the current lighting industry.
Foshan Lighting attaches great importance to custom management two years ago, and has been implementing a strict custom management system to avoid unnecessary waste and loss for the company. As for the future customization plan, Zhou Zhaopeng said that Foshan Lighting will meet the requirements of future personalized products under the premise of safety first, and get rid of the fact that some products of Foshan Lighting are relatively simple and low in technical content, and they will also learn from domestic and foreign. Successful cases are innovated to meet the requirements of different customers.
