Status LED lighting products and future trends
With LED lighting products market penetration has increased annually, each luminaire manufacturers to locate new product development focused on LED lighting products. LED as a new technology led the development of related peripheral to its various technologies, while developing gradually produce a variety of unexpected problems, but also by the new market participants of their own existing strengths to redefine the market.
Popularity of LED lighting technology, because of its low energy consumption, is seen as the ideal replacement for traditional energy giant lamp products. Coupled with its rich colors, it is widely used in home lighting, commercial lighting, landscape lighting. With the continuous improvement of LED luminous efficiency, cooling technologies mature, drive technological advances in recent years began in the indoor and outdoor lighting force.
Interior products and the people living closer to the huge market potential. Domestic market sales are mainly LED lamp, ceiling lamp, bean pot lights and track lights. Early downlights and spotlights basic selection of single particles of LED, through the design of different circuit boards to accommodate different power and caliber.
Such products are mainly three problems:
First: Because of the variety of techniques to master the LED has a higher failure rate lack of product once the failure of the product needs to be replaced, rather than the traditional product as long as the light source can be replaced, this way, the maintenance costs are very high;
The second is: uniform circular spot of light emitted from the LED is not a designer needs, but the superposition of several spots;
Third: Different LED particulate composition and caliber of product need to re-structure, optical and thermal design, lead to the design costs, tooling costs, warehousing costs and manufacturing costs increase accordingly.
To solve this problem, and now LED products also have some of the trends. For example, the traditional QRCBC, QR111 halogen lamps, using the same specifications of the LED light source, both using the original transformer and lamp body, and can replace traditional lamps as the light source images.
In addition, the use of COB packaging and in line with the trend ZHAGA light engine specification to standardize LED light source, increase the size of the luminous flux in the same circumstances, reduce design and manufacturing costs. For lighting, the ultra-narrow beam angle is reflected in one of the advantages of lighting manufacturers to design and manufacture.
Dimming is the development trend of lighting products. Domestic interior products primarily dimming 0 ~ 10V, is still relatively small in the international application more mature DALI dimming. Because realize LED dimming may cause color drift problems, dimming requirements are no longer simply tune voltage regulator current, and to PWM based. But it also brings EMC problems to be resolved.

In the choice of color temperature, and lower domestic 2700K color temperature tends to bring the warm and comfortable feeling. In addition, the product also of particular concern for indoor light biosecurity, as well as a variety of filters designed to achieve different light effects.
There is the tendency of the flexible circuit board color to yellow to better mixed mainly low color temperature light. Another type of flat light, but the market is more concerned about the date of its light uniformity, general decoration lighting.
LED product actually is the product, the light system light.
This makes it three meanings:
First: the light emitted by the product to meet the owners, designers and stores the request, both qualitatively and quantitatively on must meet. In reality, it is often the sales staff to communicate with the designer as a measure of power based on the amount of light, that increase the amount of light should increase the power, this is actually a serious mistake;
Second: As can be selling products, should meet the requirements of the owners and designers from the appearance, quality, performance;
Third: From the point of view of the system, enterprises should be applied, the products, construction, dimming and services give users systematic support, giving professional users, a full range of applications from the whole package.
Myth lighting:
It appears LED technology, which greatly enriched the lighting products, lighting a lamp a light source is no longer able to conquer the world, smaller, thinner, more functional products in foreign markets rapidly. LED as a need for a variety of knowledge-based products, design of a product and the soul, so to grasp the trend of product design, rather than relying on low-cost marketing, regardless of the quality of the marketing strategy.
