Sunrise industry to see the broad road of the development of LED lighting industry

Currently, LED lighting technology matures, high-power LED light effect has been achieved 100lm / W or more, while many cities in the past two years, energy-saving street lighting, commercial lighting, indoor and rapid development of the situation, have proven alternative to conventional lighting, semiconductor lighting has become possible. led lighting as a sunrise industry gave birth to the enormous business opportunities Sogou, many lighting companies in order to seize the valuable opportunity to seize more market, create more effective, are trying to develop a variety of led lamps to meet the needs of users, and even some The original does not produce lighting products have also launched the focus of the real estate network of LED lighting, lack of professional knowledge as lighting, lighting, market research is not thorough, lighting business development there is no scientific and rational planning and a lack of foresight on the future development of the industry, resulting in semiconductor lighting products now chaos.

Guangzhou Guangya Exhibition this year's blowout lighting can be proved go2map, similar in most enterprise products, and the lack of new ideas, and the cost price of the problems are exacerbated by limited competition in the market. The development of the phenomenon of industrial chaos, many colleagues are worried. Science and technology in today's scientific contradictions restricting the normal development of industry, 17173, business investment to profitability, customer demand-driven dislocation, Relationship Marketing, Government Executive consciousness and did not properly guide the direction of industrial development, such as the LED market Gall light, more a combination of satellites led light lamp, now some of the LED lamp, incandescent glow from a certain distance from some of the led light bulbs, some non-standard LED lamps, LED tunnel lights. They failed to correctly understand the conventional way of lighting and lighting requirements of the special nature of go2map, but according to the appearance of conventional lighting production, that is, the appearance of the same light, light is light, energy-saving lighting is the light. Interior lighting requirements really are: environmental requirements and different places according to standard illumination, no strings of light, not quite a flash Dragon, soft and comfortable with a certain degree of lighting, we also commonly referred to mood lighting, lighting scenario (It should be upgraded to mood lighting), as the fourth-generation light sources of today's revolution in semiconductor lighting products LED, lighting can not only meet these requirements but also the best choice.

Outdoor lighting of LED products focus more demanding real estate network, there are many outdoor lighting products uncertainties affecting the application, so outdoor lighting is also the most difficult lighting products. Lighting is a complex system, which is composed of many components of the overall electronic components for the demanding work environment, making the working environment must be considered in light of various factors to ensure that is not affected. Meanwhile, heat the need for structural design, reliability of power supply, lighting drag requirements, scientific and rational distribution of light, to have the art of ornamental design, etc. must all have the final led lights manufacturing to meet the requirements of different lighting fixtures.

With the light of scientific rationality, lighting design, etc. There are still some unresolved issues. Some of today's blind road network over ultra-high power led street women, the existence of poles of the load poorly designed lighting maintenance difficulties, (the real modular combinations of requirements: not just for heat, mass production, required level of protection , also consider ease of maintenance), the brightness of the stringent requirements of highway is not enough (just up the road lighting lamps not only have to take into account the effect of light-induced LO), high-power and low power security risk. Some LED street lights installed from the situation, the width of the road (lane) and lighting installed Yang angle (GB not a recommendation to exceed 15 °) issues outstanding. Because some companies focus on the lack of road experience in home decoration lighting network, light fixtures with defective design significantly more than 15 ° of elevation and easy lamp installation exceeding a certain string of light. Some roads in order to achieve wide brightness requirements, installation angle and even the use of cast light installation, the driver of the vehicle to a security risk. Light distribution in the way of lighting, LED is superior to conventional lighting with the light, you can try using symmetric and asymmetric methods of science dealing with lighting brightness demands, particularly the effective use of motorized vehicles and the level of non-motor vehicle road lighting pole , non-motorized vehicles exceeding the brightness of the light distribution using asymmetric means to compensate for the brightness of motor vehicle lanes, Guangdong Real Faith Metalworking Co., Ltd. The successful installation of such cases to prove the scientific and practical way.

Xishan "light" 500 solar led street light

WASHINGTON reporter Yang Guanrong report "when the solar lights will be lit at night, be convenient?" Recently, Xishan "green light project" a leadership group this year to install 568 solar led street light for preliminary acceptance.

"Green light" implementation of the project is the implementation of clean energy strategy Xishan, the concrete embodiment of a low carbon economy, it is not an end to the mountains of rural history of public lighting facilities, to achieve a "low-carbon, green, energy saving, environmental protection" goals. Up to now, more than 300 million investment in Xishan District in Haikou, Biji, united neighborhood offices, installation of 568 solar street light. Technically, this 568 year solar lights can be reduced more than 50 tons of carbon dioxide emissions.

Since 2008, the Xishan mountain village in the rural areas, especially roads, public places and schools to promote use of solar photovoltaic lighting technology. Through the city, district, street (community, village groups) three linkage, integration of resources, integrated planning, to point, and the application of modern scientific and technological achievements to the new socialist countryside construction. "Green light" project goal is, from 2008 to 2013, with six years, invested 24 million yuan in rural street, rural public places, school district more than 3,000 solar led street light installation.

Small solar lights that the community can save much energy?

Even so, such as the 2013 Xishan can be installed using 3000 solar led street lights, annual savings of about 1.3 million kWh of electricity and 460 tons of standard coal and reduce carbon dioxide emissions of 300 tons.

Description AC power LED lighting protection

The current global energy shortage concerns rise again in the context of energy conservation is an important issue facing the future, in the lighting field, led light product applications are attracting the attention of the world, LED light source as a new type of green products, is the future trend of development, will enter the twenty-first centuryLED Represented a new era of lighting.

In the power circuit on the primary side of the circuit, to solve transient inrush current is typically metal oxide varistor (MOV). These devices will clamp the input surge current at a voltage level, the level of the power components can not be affected and work. The main selection criteria including MOV voltage, energy performance, and peak pulse current handling performance.

MOV MOV operating voltage is the breakdown can not work properly (become conductive) and voltage level. The voltage is usually the first to determine the parameters, and simple. To specify the operating voltage, line voltage equipment will have to increase by 20% to allow for growth in the power system voltage. The aim is to ensure MOV transient events in the system to respond, not react to the temporary status. Figure 1.

Integrated device helps reduce component count

Under normal operating conditions, applied to the MOV on the AC line voltage will not exceed the device maximum AC RMS voltage (VAC RMS) rating, and assume that as long as the transient energy does not exceed the maximum rating of the MOV, short time transient events can be clamped in a suitable voltage level. However, sustained abnormal over-voltage / limited current conditions (such as neutral loss) may lead to MOV into thermal runaway state.

Usually placed in series with a thermal cut MOV (TCO) device to protect the MOV from overheating damage. A typical line voltage transient protection scheme can also be integrated an overcurrent protection devices (such as fuses), to protect the system from the over-current exceeds a predetermined level of damage caused by overload.

Over-current conditions and thermal runaway

Tyco Electronics AC 2Pro. Device is a polymer positive temperature coefficient (PPTC) element and an MOV components into a thermal protection device in order to overcurrent or overvoltage condition provides the reset function. This integrated approach can help device manufacturers meet IEC61000-4-5 and IEC60950 industry requirements.

Unprotected standard components are usually limited to MOV 275VAC RMS, in order for the universal input voltage range. Loss in the neutral conditions, they may overheat and negative results, even if the circuit has been used upstream fuse or power resistors.

AC 2Pro device of PPTC devices help prevent thermal runaway, rheostat to maintain the surface temperature to 150 ° C and prevent the device from overvoltage transients to the insecurity caused by the temperature.

Work

Although applied to a MOV on the AC line voltage is generally not exceed the device's maximum continuous operating voltage rating, but may occur beyond these limits over-voltage transients. 2Pro PPTC device will integrate technology with MOV, MOV when a long period of sustained overvoltage condition, it can enhance the over-current and thermal protection.

In the case of overvoltage transients, shown in Figure 2 of the neutral loss events, 2Pro devices in the PPTC element will heat, escape and enter a high impedance state, MOV device to help reduce the risk of failure.

LED bus stop lighting systems are particularly suitable for rural areas?

After nearly two years of the pilot, Hangzhou Xiaoshan region currently has 54 rural bus stop using solar power led lighting system. Xiaoshan passenger transport infrastructure headquarters confirmed that this lighting system is the latest in the next year before the Spring Festival, the region has completed the transformation of the rural bus stop in use.

Lighting system especially suitable for rural areas

It is reported that rural bus stop, no lighting, it is prone to the site to be touched or been touched Yexing Ren and other accidents. To some extent, bus stops lighting lighting even more important than the road. However, due to its location in rural areas, rural bus stop, take more trouble with the municipal people's power, then the cost of electricity is also high.

Back in September 2008, Samick line Xinyi village bus stop on both sides of roads, installation of LED lighting systems, this is my first trial area LED lighting system. This lighting system consists of solar power and low-carbon of LED lights. Main function is to use photovoltaic technology to convert solar energy into electricity. LED is a semiconductor light-emitting diode abbreviation. In the LED lighting systems, photovoltaic electricity will be stored in batteries, then the supply of LED lights, complete with its light emitting characteristics. This system, solar energy is completely clean, light-emitting diode is an environmentally friendly, energy saving, power efficient solid-state light sources. LED lighting is the next generation of new sources of energy and the perfect combination.

Xiaoshan passenger transport infrastructure Jin Wei, head of the command are said to use LED lighting in rural public transportation system not only solved the difficult problem of electrical connection sites, even more gratifying is that this system was originally designed for the 7th consecutive rainy days as usual to generate electricity. Last year, Xiaoshan nine consecutive rainy days, at night, bus stop lighting systems to work as usual.

Stops in each province costs 3000 yuan

Jin Wei calculations are to reporters, the original bus stop site uses the fluorescent lighting. A 8 m bus station, for example, to install fluorescent tubes is 30, each fluorescent lighting 10 hours per night, the bus stops a year in electricity (commercial electricity prices) needs to 4489.5 yuan.

Use of LED lighting systems, using solar power technology, no electricity costs. However, this system was the battery replaced once every three years, and to install security devices, this is a major expense. According to the staff, for this system is 12 volts, will not cause injuries to passengers.

According to reports, the half of the transit site uses LED lighting systems, electric lighting, the other half still received the same time lighting, LED fluorescent lamp night power consumption of only about 30%. Year, the use of LED lights to save electricity bus station is about 3,000 yuan.

It also is not fluorescent tube replacement cost. Fluorescent tube life is generally two to three years, the cost of each lamp to buy $ 8. The LED lamp life of 100,000 hours, according to the design for 20 years without replacement. LED Lights Lamp replacement cost is not generated by the number of pens.

The end of September there are 580 sites, "light"

In the early 54 pilot rural bus stop in New Street and Town have a pilot up to justice, each with 10, Puyang, eight, six Canton Town, temporary Town, Nga town Ning around town all four, wearing the village and town on the river 2.

It is understood that the end of September this year, 580 rural bus stops will be installed on the LED lighting system, until next year before the Spring Festival, the district soared to 600 rural bus stop, the cost savings will be considerable.
