LED lighting into the track cost and technical difficulties have yet to be overcome

LED lighting seems to be on track, but there are still many problems to be solved. From the hardware, for the average consumer, the price is often the key consideration, but the current cost of LED lighting is still high, in addition to the LED's own yield problem, the structure is too complicated and the main reason for the current high cost of LED lighting. A bulb-type LED lighting product that replaces an incandescent lamp needs a substrate, an LED, an ACDC converter, a voltage regulator IC, and a large-area heat sink. In particular, a large-area heat sink has long been an unavoidable bottleneck for LED lighting. The emitted infrared light emitted by the light is less, and the temperature rise is slower than the incandescent light and the fluorescent light. However, the LED itself generates a temperature when it is in operation, and due to the characteristics of the package, it is difficult to dissipate, and the high temperature needs to be dissipated through the passive heat sink. Keeping the LED temperature at a permissible level can reduce the heat exhaustion of the LED and prolong its product life. At present, aluminum products are still the main material. The larger the area, the higher the cost.

Thermal design varies

The design of the thermal module is also closely related to the quality of the lamp. Under a good thermal design, the light emitted by the product is stable and has a long lifespan; this is already the case for indoor lighting modules, not to mention outdoor harsh environments. Street lights and street lamp modules, especially in the desert or the equator, are subject to rapid changes in temperature, which is a major challenge for LED lighting. After a long period of development, traditional lighting products have become quite mature and have fewer changes than LED lighting. They have long been able to operate in a complex environment. However, LED lighting has just begun to develop. Although the same as LED lighting products, but the final product design has been a far cry from afar, there are only a few different interpretations of the thermal module.

In addition, at present, the LED lighting hardware is still in a transitional design. Current products, especially home appliances, adopt alternative products. It is LED lighting to adapt to the existing home lighting architecture instead of changing the existing structure to adapt to the LED. illumination. The main reason is that the existing lighting architecture has developed for many years. To meet the LED lighting that has not yet fully matured, the current equipment has not been completely replaced. Especially the replacement of fluorescent lamps is the most troublesome, especially since most consumers are already accustomed to using relays. However, LED lighting does not require high pressure to start up, but it will cause product damage, knowing that consumers should be advised to remove relays. However, it is still necessary to install a buffer device that prevents the relay from generating an instantaneous high voltage to avoid inconvenience, but it also increases the cost.

Policy norms can make the industry track

In terms of software, due to the high cost of LED lighting, consumers are also not easy to accept the power-saving advantages that they have to bring for a long time. Only the use of the public sector and the provision of reasonable subsidies can accelerate the operation of the entire industry chain. In addition to the promotion of the unit, it is also necessary to carry out relevant specifications for the existing LED lighting equipment, especially for product life, safety, and product reliability, etc., all of which require comprehensive specifications. Street lights, in particular, require rigorous specifications, ranging from life, recession to light, and evenness of light. These are different from street lights. Street lights have a function of landscaping and lighting. It is only one of the additional features that can also allow light to be unequal. However, street lights affect traffic safety. This does not create the danger of driving on the road. If it causes glare or does not cover the road surface, etc. There are guidelines that can be followed.

There are also industry sources that LED applications in the LED lighting market is still relatively small, but the development potential is encouraging. LEDs have established themselves in markets such as decorative lighting, design and signage. LED has made breakthrough growth in the home lighting and office lighting markets in recent years, covering all areas from the end-consumer market to professional applications, where the professional application market share has grown rapidly, and the end-consumer market is expected to Large-scale breakthrough growth occurred around 2010/2011. LED lighting applications in retail stores and restaurants are also growing.

However, LED lamps are not meant to completely replace traditional indoor lighting sources. In addition to the price, the reasons for the popularity of LED lighting include the improvement of the light quality of LEDs, the increase in lumen efficiency, and the decrease in manufacturing costs. In other words, a balance must be found between light output (lumens) and purchasing and operating costs and between light output and energy consumption.

Creating LED Lighting Blue Ocean

Looking at the LED lighting market, it is still not mature, but the market size is expected to be on the horizon. After all, LED lighting is a trend in terms of cost and characteristics. The future market still needs to start from the public domain, such as Japan and Europe directly through regulations. The direct effect on the market, the industry will thus fully develop LED lighting equipment, the cost is also more likely to reduce, and manufacturers can not thus sacrifice product quality, quality control, depends on manufacturers and the official for product life, safety Sex conducts complete specifications. For example, in Japan, LED lighting is mostly dominated by traditional electronics companies. Naturally, product safety and quality are required. For example, OSRAM and Philips have begun to introduce products, but in addition to general lighting applications, they have introduced many products. For ambient lighting products, situational lighting is also LED lighting advantages over traditional lighting, and only need to maintain safety, for the lumens and uniformity requirements are not as strict for lighting.

However, the biggest bottleneck is still in the general lighting architecture. In particular, the current general lighting power is still based on AC power. After the switch to solid state, it is bound to need to be converted. In particular, the power supply structure adopted by large-scale lighting equipment is similar to PC, but the current conversion. The efficiency is still 85%. The energy consumption caused by the conversion is still unsatisfactory. It will inevitably need to be converted to a DC power platform in order to take advantage of LED lighting. With the conversion of micro DC power, it will be easier to combine with alternative power generation facilities to make use of its environmental protection and energy saving. Advantage. Taiwan LED lighting manufacturers also need to separate from the simple assembly concept as soon as possible, re-examine each link of LED lighting, in order to jointly create LED lighting blue sea; especially LED lighting market is still sprouting and groping, we must lay a good foundation for the product, only have the opportunity Deepen consumer's good impression on LED lighting. Otherwise, with most of the current assembled products, it is not only impossible to provide reasonable warranty, but also the situation of unstable light and light uniformity, coupled with high prices, it is difficult to gain consumers' favor.
