Development of high brightness of the chip facing bottlenecks
Current, the further development of semiconductor lighting market requirements luminous efficiency of the blue LED highbay light to be rising, costs are declining. Cree LED chip based on silicon carbide has been achieved 200lm / w light efficiency production, R & D level of luminous efficiency can reach 276lm / w. LED chip costs down and enhance light efficiency race currently encountered several development bottleneck.
The blue chip exist Droop effect. Under the condition of a large current density, external quantum efficiency of the light emitting diode will decrease, tests showed Droop effect is caused by the Auger effect, including a variety of reasons, this effect limits the blue chip used in a large current density, thus hindering the decline in the cost of lumens.
The second is a green energy gap (Green GAP) and the energy gap in red (Red GAP). Wavelength from blue light into green band, the quantum efficiency of the LED will be decreased, such as 530nm green quantum efficiency drops quickly in a dark red spectrum; terms for red, the internal quantum efficiency can reach 100%, but the ideal white light source in the orange-red light emitting wavelength (e.g., 614nm), and its efficiency is decreased rapidly. These effects limit the green and red chip optical efficiency improvements, delaying a future generation of high-quality white. In addition, the efficiency of the green and yellow LEDs also by the impact of the polarization field, and this effect will become stronger with the higher concentration of indium atoms.
The third is the extension of heterogeneous growth problems. Since the epitaxial growth, crystal defects formed a large dislocation density and defect, resulting in the decline in luminous efficiency and lifetime decreased. Blue chip regardless of silicon carbide, sapphire, silicon substrate technology is heteroepitaxial, in the presence of lattice mismatch between the substrate and the epitaxial crystal dislocation, and also because the difference of the thermal expansion coefficient in the cooling process after epitaxial growth The thermal stress is generated, resulting in the epitaxial layer defects, cracks, wafer bending. Substrate directly affect the quality of the crystal quality of the epitaxial layer, thus affecting the efficiency and life. If for using GaN homogeneous substrate by epitaxial growth, using a non-polar, can minimize the defects of the active layer, so that the current density of the LED chips is 5-10 times higher than conventional chips, significantly improving luminous efficiency. Reportedly Seoul Semiconductor using the homogeneous substrate the development of nPola new products, compared with the current LED brightness in the same area five times higher, but the the GaN the homogeneity substrate for the LED is still too expensive.
Overall, in the future development of the blue LED highbay light, flip chip, high-voltage chips, silicon chips are the future trends. The flip chip good heat dissipation can increase the injection current, do not fight the lines can improve the reliability of the product in the application process; hypertension LED chip can more closely match the supply voltage to improve power conversion efficiency, plus custom IC power most suitable for LED bulb; silicon LED chip can be epitaxially grown on a 6-inch or 8-inch silicon substrate, can greatly reduce the cost of LED to accelerate the advent of the era of the semiconductor lighting applications. For other colors, the red LED chip and green LED chip light efficiency there is still much room for improvement, further enhance light efficiency with the red and green LED chips, white is not necessarily the Blu-ray The form of the LED chip and yellow phosphor RGB or other form of the future white package may change a lot.

Beware of energy-saving lamps become a new sourc e of pollution Promotion of LED lights to be environmentally friendly at the same time
Alternatives as incandescent, Led highbay light can not only for the residents saving, while the energy consumption by reducing fossil fuel power plants to reduce emissions of carbon dioxide and other greenhouse gases, has multiple purposes. However, in the many benefits behind the pressure on the environment, energy saving lights-out and update, but few people are concerned. Recently, some experts have called on the Government to vigorously promote energy-saving lamps, "one step ahead" in the environmentally friendly processing must be done to become a new source of pollution to avoid energy-saving lamps. Synonymous with the energy behind the hidden large in the consciousness of the average person, the energy-saving lamps are often environmental protection, energy saving, etc.. However, few people will know that, if a large area, while at the same time they did not get enough attention in the post-processing if, then, for the already fragile ecological environment, led highbay light is likely to become another huge sources of pollution. And all this, because an ingredient contained in the energy-saving lamps: mercury. Learned from the lighting industry, subject to the limitations of the manufacturing process, energy saving lamp products inevitably with a little mercury, which is commonly known as mercury ingredients. Although an ordinary energy-saving lamps are usually mercury was only 0.5 mg, but this small amount of mercury, pollute the environment, "powerful" but staggering - 1 mg of mercury into the ground, can be caused by about 360 tons of water by pollution, thus calculated, a waste energy-saving lamps, such as improper disposal, and ultimately may pollution to 90 tons to 180 tons of water and the surrounding soil. According to the person in charge of the environmental protection department, while vigorously promote energy-saving lamps, the processing of waste energy-saving lamps, rarely receive attention and publicity. Many people for the waste of energy saving lamp, often like ordinary garbage fling trouble. Can imagine where the mercury enters into the soil and water, over time, will soon become the new "environmental killer.
Since the energy-saving lamps might cause such a huge environmental hazard, then we should abandon the use of energy-saving lamps? The answer is clearly no. From the technology and management of two ways, we are not hard to find the energy-saving lamps energy saving at the same time, an effective way to minimize environmental pollution.
Experts for the recycling of Led highbay light in Western developed countries attach great importance to and has a corresponding specification. The U.S. Environmental Protection Act and the original owner of the waste in the end you want to be responsible for their own waste, which fundamentally curb free to dispose of the emergence of the phenomenon. Seven states in the United States, have legislation to ban the energy-saving fluorescent light bulbs directly on conventional garbage bag, at the same time of the year to require a specific time period to dispose of used compact fluorescent bulbs, to facilitate residents. Our neighbor Japan, land and people, the ambient pressure is made in the fluorescent lamp recycling world's most comprehensive provisions. In addition to the government dedicated collection points set, Japanese folk there are also a large number of energy-saving fluorescent bulbs recovery mechanism. In Hokkaido, waste battery recycling and waste fluorescent lamps, even 93% is collected by a private environmental organization, and the remaining 7% by the manufacturers responsible for collecting. European countries such as Sweden and Germany, also through the sales system recovery and community recovery of two parallel channels to the recycling of waste energy-saving lamps.Antifouling need to grab the source of the the antifouling need to grab the source antifouling needed sources of corruption antifouling needed sources of corruption.

Unlimited potential of intelligent lighting Gradually become the new darling of the LED industry
Intelligent lighting had become the LED highbay light industry trends according to their needs, users can set the scene lighting, so as to control the color and brightness of the LED lights to meet the lighting requirements of different occasions. Not only that, through the installation of sensors, LEDs have a "perception" to self-adjust the brightness according to the surrounding environment.
Force field of intelligent lighting
"Shine light as long as the shine is enough." In the Led highbay light industry view, the only way it will not light pollution and waste. "If the surrounding environment is very bright, or not around, the light emitted will be reduced, in order to achieve the environmental objectives; if the outside world is very black, or when someone passes, especially at midnight when the light will become brighter . "the Fujian Quanzhou an enterprise.
The intelligent lighting unlimited potential had become the new darling of the LED industry
It is understood that the cultural and creative solar crystal clear Hi-Tech, crystal blue photoelectric Quanzhou enterprises have been in R & D was networking applications in the field of LED. Existing manually operated switch lights mode there are certain drawbacks. Instance, is fixed to the time setting of the manual control switch lights, due to seasonal replaced diurnal cycles, cloudy fog, rain, and other factors cause the daily light switch time, dark and bright varying degrees; equipment also prone to tripping, the phenomenon of the lamps loss and large, can not guarantee the timely repair and replacement of damaged lamps. "the crystal responsible person Transtech Urban transportation Creek through smart management platform, only need a computer, the little mouse on The fine control of each street lamp, flexible on and off, dimming, fault warning and ensure the quality of the lighting at the same time, maximize energy savings.
Create new profit growth point
"We often change phones, change is not bad, but the new phone has many features. Therefore a product to capture the market must provide more added value and new functionality is also true in terms of the LED products." In many Quanzhou photoelectric enterprises responsible person seems, the current LED terminal price continued to decline, the profits will shrink, and build intelligent lighting into a new growth point of the industry.
Insiders rough estimate, the next few years, the market size of the LED light source will exceed 100 billion U.S. dollars. Domestic intelligent lighting market penetration is still less than 2% of product application is mainly reflected in the dimmable LED highbay light, adjustable color temperature LED street lamp monitoring and other aspects. intelligent home lighting, intelligent road lighting market will greatly expand even 20% penetration, tens of billions of dollars (a total of one hundred billion yuan) market space waiting to be discovered . "
In addition, the value-added products will also be greatly improved. Philips previously introduced a use iPhone iPad (with built-in application) WiFi control LED bulbs can independently adjust the brightness and color, the entire system priced at $ 199.95, even if a light bulb is purchased separately also need $ 59.95, the price of ordinary LED lamp several times.
According to the survey found, with a power driver chip LED lamps ex-factory price 20-30% higher than ordinary lamps. This alone intelligent configuration can be thought lamps to increase by at least 20% of the gross profits, while some high-end dimmable products can even reach 30%.

The latest classification of the led highbay light
Categories: made by the straw hat type of small power LED LED highbay light, power supply with RC Buck circuit. Extension Strawhat LED indicator LED package, epoxy encapsulated LED chip can not dissipate the heat, the light fades severe, a lot of white LED, in use for some time, the color temperature is high, gradually into a bluish turned dark. Manufacturers committed to developing low-light failure straw hat LED, but because there is no change of the package still did not change much, the light fades. LED energy-saving lamps such products, for a transitional product, low prices, poor quality.
5050 SMD LED energy-saving lamps categories: made in power by 3528 or 5050 SMD LED LED energy-saving lamps, power is also commonly used by RC Buck circuit, some manufacturers using constant current circuit, compared to the straw hat LED stickers piece LED heat a little better, the thermal conductivity of the substrate, with the aluminum plate, can export part of the heat. However, due to the heat of the LED or ignored, many in power SMD LED energy-saving lamps, radiators, still use the plastic shell is still serious, the light fades. Using resistive and capacitive buck low-end power, grid voltage instability, the current fluctuations in brightness fluctuations, affordable, quality slightly better high-power LED energy-saving lamps.c
Three categories: made by the high-power SMD LED LED highbay light, power generally constant current isolated circuit, that is, a constant current of 5W LED, usually five 1-watt LED chips in series, using constant flow 300mA current source power supply, wide voltage power grid fluctuations, the current does not change, the luminous flux that maintain a constant brightness 5 SMD LED welded on top of the aluminum plate, aluminum plate and then bound to the radiator, the use of heat timely quickly dispersed, ensure the LED chip temperature below the LED allowable junction temperature of the LED energy-saving lamps in order to ensure real and effective life. Type of LED lights is the high price, good quality, but also the direction of the development of the LED energy-saving lamps.
A good LED energy-saving lamps, should be composed of four parts: quality LED chip, constant current isolated power, relative lamp power radiator, light diffusion effect is soft but not to the point light shade.

LED lighting drive technical knowledge
The recent LED driver, concerns a high degree of practical application and product design innovations in energy-saving concept popular today, led lighting more and loved by everyone. LED lighting equipment at this stage the main problem is that the price is still relatively expensive, limiting its rapid spread, in order to make LED lighting more cost competitive, in addition to the LED itself is also very important to select the appropriate driver. LED lighting driver problem special compilation of relevant content for reference only.
Q: structural model of the high-power products are closely connected metal casing and aluminum circuit board, housing and circuit board electrical isolation only in the aluminum plate to achieve this?
A: Yes, this non-isolated power LED applications to pay attention to the main points. LED aluminum plate can do general isolation voltage of 4000V.
Q: For small power LED to take power from 220 volts AC mains power using what program?
A: The easiest way is to take power from the AC mains using capacitive current limiting buck, but the disadvantage is that LED charged, insecurity, and low power factor. The best approach is the use of switching power converters, made of isolated constant current power supply, the output current is constant and adjustable design, but also pay attention to the input power factor. The latter has a lot of mature circuit, but designers also point effort in switching power supply technology up and down the job.
Q: In addition to constant current drive, the display screen pulse drive? Pulse drive, how to control? Drive power how calculated?
A: Absolutely. Mirror circuit of the constant current source + PWM modulation, theoretically, the luminous efficiency can be done higher, but in fact the leakage current when the ON-OFF switching loss and OFF into consideration, efficiency is not so ideal and does not apply High-power LED driver. In addition, the LD laser diode is also used pulse drive, will become part of a new development direction is not known.
Q: the size of the high-power LED package and drive voltage ordinary LED What's the difference?
A: The small, high-power LEDs, the same color as forward drive voltage characteristic is the same. Different package because of its different cooling conditions, the difference between the light fades. At small power packaged LED is about the light fades in 1,000 hours to decay to 70% of high-power packaged LED decay to 70% at 10,000 hours. As indicated by the LED because of its small operating current to reduce light decay exponentially.
Q: LED lights work properly or not, the quality is good or bad, with the lamp body heat is crucial. Cooling of high-power LED lights in the market are now using natural cooling effect is not ideal, what recommendations?
A: The temperature protection is a must, which is the need of the product itself, and is also responsible for the customer. That the number of temperature protection is appropriate? If calculated according to the following situation: Suppose the maximum ambient temperature, the summer is 40 ° C in summer sunlight exposure under 50 ° C, 50 ° C ambient temperature is the actual, see generally high power LED specification junction temperature can withstand 120 ℃ , the thermal resistance of the chip to the aluminum plate, specifications generally recommended 10-15 ℃, the LED board to ensure that 120-15 = 105 ℃. Then, to retain temperature difference take 50 - 105 ℃ intermediate value of 77.5 ° C, general electronic components is reliable to the temperature of 85 ℃, 77 ℃ is in line with this principle. 77 ℃ start protection, significantly reduce the current 85 ℃, 90 ℃ thoroughly complete product temperature protection function is recommended. Of course, the actual product application, must surpasses this condition to much more stringent, LED highbay light can not maintain high heat for a long life.
Q: Will the high-power LED thermal standards, and how to choose the heat?
A: LED working temperature T1 = ambient temperature To + Ploss * Thermal Resistance RR = LED package thermal resistance Rled + LED and heat sink contact the thermal resistance Rled-link +? Heat sink thermal resistance? RLink can +? Heat sink and air heat resistance Rlink-air.
Choose the LED, the thermal resistance of the general package after the same heat sink thermal resistance and volume-related, often subject to the limitations of space, often become the focus of the thermal design LED and heat sink contact area and heat sink area in contact with air toothed, fin-shaped, etc., in order to increase the contact area of the heat sink and the air, often the heat sink design. If the heat sink is installed in a small space or a fan (chassis), the need to consider the impact of heat flow, generally based on the modeling of the body parts, the use of fluid dynamics analysis to estimate the heat flow direction and speed, to calculate the air stream can take the heat.
