Explain the correspondence between visible light rate and illumination and power

How should companies connect with designers?

First, you first determine the customer base of your product. (For example, you are an outdoor landscape lighting manufacturer) Your customer base is a landscape lighting designer, or a landscape architect, or a lighting engineer;

Second, after you have decided, you can participate in relevant designer activities, sponsor or engage in some activities (the landscape design industry has activities every year);

Third, emphasize the characteristics of your product, or the core. You have to do the products of others, you have products that others do not have, you must pay attention to the light effect of the products;

Fourth, you have to give the lighting designer a solution to the problems he encountered in the design. For example, what products are used where appropriate, how many distances, and so on. Rather than the designer wants to illuminate the fixtures you provide. You have to guide the lighting designer. For my requirements for lamps, please read some of the requirements for my selection of lamps in the 38 degree lighting forum public platform. The details of this article are written.

How to make the color temperature stable for dimming products?

At present, if the quality of the light source is good, the dimming current has little effect on the color temperature, and is generally in the half step. Light source materials, especially phosphors, require better thermal stability of the silica gel. This ensures that the color temperature change during the dimming process is within the range of the human eye.

In addition, the current popular color temperature source will be an expanding market. This is another topic.

Is there a lot of utility patent litigation? Are most companies gone?

Since most of China's lighting companies have weak innovation capabilities, they mainly apply for utility model patents.

The patent infringement disputes are complicated to handle, the cycle is long, the procedures are complicated, especially the evidence collection is difficult, and the local protection and judicial resources are insufficient. After the enterprise accuses, the economic compensation is limited, so the general enterprises are not very active, and are not willing to This is more energy and money.

This is an important reason for China's lack of innovation capabilities. If the country does not change this situation as soon as possible, China will not have real innovation. If it is said that innovation is the only way to shout slogans.

There are so many exhibitions, which one is the most effective?

For the show, many people like you want to know which one is most effective. In fact, this is a question without an answer. The effect of the exhibition is not only from the exhibition itself, but also related to the positioning of the market, the preparation of the exhibition, the marketing plan, the sales strategy, the design concept and the performance of the on-site salesman.

According to my personal experience and the participation of friends around me, the effect of the Frankfurt Lighting Fair in Germany is quite obvious, but this exhibition is also difficult to participate. In addition to the North American market, LFI (LIGHTFAIR) is also good.

In addition, for the exhibition, I give a few points:

1. Don't blindly exhibit, not the people around you are going to be good exhibitions, which need to be determined according to their own products and market positioning.

2. The exhibition is not necessarily a good result of the hard work of the big booth. Because people's buying psychology is different, large and hard-boiled booths give people the same pressure as a specialty store. Many small customers who are just starting out are afraid to come in.

3. It is necessary to do a good job in the marketing plan and staffing of the exhibition. It is not the participation of all the salesmen of the exhibitors. Avoid good customers to let the general business pick up, but there is no way to convert orders and waste customers.

4. Foreign exhibitions, local exhibitors are relatively high-quality potential customers, who can visit and market during the exhibition. Before the exhibition, you can see the list of exhibitors on the official website of the exhibition, conduct customer analysis and marketing plan before the exhibition.

From industry to trade and investment, what pit?

Life is a process of emptiness. Before Zhou Ming was responsible for the brand, he did not have the professional knowledge of the brand. He had experienced the failure of the media industry to understand the Internet promotion. Later, Lin Dong gave a platform. And because of the participation in the investment of Hanyuan, and then the need for a director to leave the job requires a person to promote the capital market, Lin Dong gave the opportunity to test the qualification certificate of the Secretary, and then very fortunate to participate in many projects of the company.

In the process of growing up, I actually made a lot of mistakes, and I also encountered a lot of hurdles. I fell into a lot of pits. Most of my conclusions were that I didn’t have enough ability, and I was too wise, and I was light and heavy. I am fortunate to be able to reach a large number of entrepreneurs. Every time I see entrepreneurs cherish the time, such as gold, smashing the road, blue and white, scars, and you can feel the distance of power and the power of growth! The thinking of investment banks is a very advanced resource allocation thinking. It is a core competitive thinking. Every position needs these two kinds of thinking. Everyone should be an investor and invest in their own time and future!

Does the speed of visible light have a corresponding relationship with light and power?

At present, most of visible light communication is expected to be a blue light component in white LEDs . However, the bandwidth of blue LEDs is limited. According to Shannon's law of information theory, to increase the communication rate, it is necessary to greatly increase the illumination of the receiving surface. When the rate is increased by 10 times, the illumination needs to be increased by more than 1000 times. This level of illumination (hundreds of thousands of lx) is not allowed from the perspective of energy saving and eye safety. This is also the theoretical and practical basis for my disapproval of high-speed LED lighting communication. However, laser-based visible light communication is not limited to this. In 2006, I used a 7mW visible light laser to achieve visible light communication at 125Mbps between two computer networks at 1Km (2002 Guangzhou Science and Technology Plan Project Research Results).

Is the constant voltage 12v power supply connected in parallel with multiple lumen lamps to damage the lamp beads?

The current-voltage curve of the LED determines that the optimal driving condition of the LED is constant current instead of constant voltage. The voltage of the same batch of LED will have a distribution. The same four chips but the voltage will not be completely 12V, direct constant voltage. When driven, the brightness of the LEDs will be inconsistent and will easily fail due to overcurrent.

Will the Indian LED lighting market recognize the brand? What are the recognized good brands there?

In the city, the country will not.

There are many local brands in India, such as Philip, Osram, SURYA, Crompton, SYSKA, FIEM, Anchor, etc.

What is quantum dot technology? Can it be applied to the LED lighting industry?

　 Quantum dots are named for their nanometer size. It is itself a light-emitting semiconductor material (such as CdSe, InP, etc.). Compared with the traditional rare earth phosphor, the quantum dot has a particle size of about one thousandth. The main feature is that the half width is narrow, the wavelength of the light is adjustable with the size of the particle size, and the quantum efficiency is high.

Therefore, there is better flexibility in color implementation. A higher color gamut than a phosphor converted white backlight can be achieved in a display application. Achieve high color rendering index and color fidelity in lighting applications. For example, using quantum dots with red phosphors to improve lumens and improve R9 index.
