LED street lamp application needs to focus on four big problems

In recent years, the rapid growth of the semiconductor lighting market in China, especially in April 2009, national Ministry of Science and Technology of 'about agreed to carry out the' ten city wan light 'semiconductor lighting application reply of the pilot project' file, but will be LED in the field of road lighting applications to a new climax.
However, industry in rapid development at the same time, the unavoidable appear some problems.
Before Shanghai street lamp management center engineering wang2 xiao3 ming2, director of the ministry of construction is pointed out that there are too many companies keen to lighting, LED lighting technology is applied to both traditional street lamp or unconventional street lamp enterprises, so that in the development and production of LED lights in a series of large and small problems and shortcomings.
If these problems can not be well resolved, in practice, LED lights will encounter more objective resistance and questions, including the maintenance and management from the street lamp units.
to sum up, the enterprise in the r&d and production of LED lights and application, should focus on the following four problems
the first is the appearance of lamps and lanterns structure problem. The appearance of traditional street lamps and lanterns, such as sodium lamp light source, lamps and lanterns, light source and electric is generally divided into two parts, specific to each product may be different, but overall, basic same. But the particularity of the LED light source, the light distribution in different ways, and now the appearance of the LED street lamps and lanterns is varied, including a lot of shape of lamps and lanterns can't meet the requirements of operation, and even some companies based on indoor standard applied to outdoor lamps. In addition, the LED lamps and lanterns and light pole connection there is a problem, almost all of the LED lights are fixed screw positioning, few coupling bolt. Can install link simple, so manufacturers spends little effort on it. But for running unit, safety in production is a foundation, the connection is directly related to the safe operation of lamps and lanterns of lamps and lanterns, so the degree of attention to it.
followed by the weight of the lamps and lanterns. The weight of the lamps and lanterns is very important, but the general LED manufacturers have not this kind of consciousness, or didn't do too much consideration to this aspect. LED lamps and lanterns for the sake of heat dissipation, the shell relative to traditional lamps and lanterns of lamps and lanterns, may be more heavy weight. But too much weight can cause certain influence to the operation maintenance.
the third is the replacement of parts of lamps and lanterns. LED street lamp parts generally have LED chip, the power supply ( Drive) And the shell parts of lamps and lanterns. Easy to bad parts mainly power supply ( Drive) And the chip. In general, the LED lamps and lanterns of chip can't be replaced, power supply ( Drive) Can be replaced, however, some products power supply ( Drive) Easy to change is not enough, or spend too much time in the field replacement. In addition, the LED lamps and lanterns of life now generally is 30000 hours, 50000 hours in the longest. If the LED chip can't change, when only replace the lamps and lanterns, caused great waste.
is the fourth power supply ( Drive) The life of the problem. Power supply ( Drive) Is the LED lamps and lanterns is very critical parts. Because many of the power of the LED lamps and lanterns manufacturers ( Drive) Is not their production, sometimes the quality of LED lamps and lanterns itself is good, often inadvertently fell in the power supply ( Drive) The above problems.
in fact, both LED itself or the quality of life, and power supply ( Drive) Quality of life, is the LED street lamp itself and embodiment of life, LED lamps and lanterns of quality assurance should also include the two aspects of content, which is LED street lamp life 30000 hours, 50000 hours, should include the power supply ( Drive) And quality of life. Can be on the market at present, the general LED lamps and lanterns manufacturer is only guarantee the quality of LED chips, power supply ( Drive) Life is another matter. Manufacturer? General guarantee 2 years, three years of less, 5 years is too little. Now, therefore, the development of LED street lamps and lanterns - power supply (a new bottlenecks Drive) , its quality restricts the development of the LED street lamp. This should be aroused the concern of the production enterprises.
