The continuous development of the LED lamp strip package technology and cooling technology in recent years, the stability of the LED lamp strip has reached a good level, the occurrence of light attenuation and color drift is mainly some copycat product manufacturers, the main reason is the unreasonable design of heat dissipation. Relatively speaking, LED lamp strip driving power supply problem is much more serious, it is the leading cause of death or flashing lamp main reason, that is to say, LED lamp driving power supply has become a short board of the LED lamp strip quality, according to the theory of barrel, life of LED lamp strip driving power supply is the life of the LED lamp strip.usually failure is a lamp – high pressure sodium,, high pressure sodium lamp, high pressure sodium lamp provisions of national standard warranty period of one year, the street lamp management unit will store a certain amount of sodium lamp, high pressure sodium lamp has mature national standards, the main parameters of its main parts size and power are unified and having interchangeability.current major fault of LED light bar in the power supply, so the main problem is to solve the power supply. But because of the standard is still a lack of LED power supply, power supply their own market, for example there are have a single road, the size is different, it is difficult to replace. With the advent of the market super power COB LED resource lights, LED tunnel lights, L LED drive power failure-prone, and the LED lamp with built-in driving design of power supply, often caused LED lamp power supply maintenance is difficulties, the lack of some manufacturers of after-sales maintenance services, so the owners complained, the influence of LED industry reputation.

Infrared thermal imaging is the industry an increasingly detection technology, general factory inspection application, main To improve the equipment operation reliability, industrial safety and energy saving for the purpose of. Factory equipment composed of electrical and mechanical, and with the application of electrical equipment detection is most to use. Also include rotation, detection of mechanical transmission device, furnace wall And the pipeline fire and heat insulation layer (insulating / cold) state detection.
Application of electrical equipment detection The low-grade damage to equipment harm and stop production, high -grade damage while in the occurrence of electrical fire. At the beginning of the different electrical equipment with electrical equipment detection of IR LED.

Detection work:
Including design, manufacture, installation and operation and maintenance work improperly will cause overheating problems electrical equipment; electric equipment Especially. the bad performance of conductivity, insulation, will bring abnormality detectable. The common causes of overheating
1, the contact resistance is too high: screw loosening or slide fastener, imbedded, oxidation, poor contact or contact area of less than the original to draw resistance is too high.

2, leakage or discharge: due to the equipment insulation is bad, such as along the surface pollution, humidity is too high, the insulation Degradation, lack of insulation from the many other factors, or over voltage.

3, overload: due to incorrect design planning, protection device of arrhythmia, or power supply demand overload and other factors will result is too more. The whole equipment load, high temperature.

4, design and construction: eddy current overheating due to improper, found in the actual detection, overheating due to eddy current should be to high.

5, poor heat dissipation slot: such as cable is too dense, air conditioning is insufficient accumulation of substation, the cabinet body ventilation adverse, equipment environment High temperature factors lead to overheating accumulated heat can not be eliminated, and speed up the insulation aging.

6, other reasons.
Detection of mechanical equipment
The heat source of rotation and drive mechanism from the “friction heat”, due to poor lubrication or component lead to mismatch and other factors, will have a lot of friction heat, causing the temperature rise, resulting in rapid mechanical grinding Loss damage or excessive vibration, the transmission efficiency decline lead to achieve precise control requirements. This kind of detection applications include electric Machine, bearing, coupling, pump, compressor, transmission device (a belt, a gear or chain) and other equipment.
Types of electrical Detection equipment By power plants, electric power transmission and distribution lines, substation, electrical room, control room, slot, distribution box and electrical equipment is Partition places, may include generator, overhead transmission line, transformer, circuit breaker, current transformer, voltage transformer, lightning arrester, the ratio set Tube, bus, reactors, capacitors, cables, wires, and all kinds of switch, switch, relay, or electricity The machine and the power equipment itself, may be the application of test to find out the abnormal issues important equipment.

Infrared thermal imaging using infrared band signal detection object specific heat radiation of photoelectric technology, the signal is converted into available Human can visual resolution images and graphics, and can be used for calculating the temperature value with IR LED. Infrared thermal imaging technology to make human transcendence The visual impairment, thus people can “see” the object surface temperature distribution.The surface temperature of objects if more than absolute zero (0K) will radiate electromagnetic wave, with the change of temperature, the radiation of electromagnetic wave The intensity and wavelength distribution has changed, the wavelength range of 0.75 mu m to 1000 mu m electromagnetic wave between called “infrared”, While the human visual “visible” from 0.4 mu m to 0.75 mu m. Infrared transmission in the surface, will be affected by the composition of the atmosphere Substance (especially H2O, CO2, CH4, N2O, O3 etc.) absorption, strength decreased obviously, only in the short wave 3 mu ~5 mu m and Two bands of long wavelength 8~12 m has better penetration rate (Transmission), commonly known as the atmospheric window (Atmospheric Window), most of the infrared thermal imager is based on these two bands were detected, calculate and display the temperature of the object surface The degree distribution. In addition, because the infrared to great part of the solid and liquid material penetration ability range, so the thermal infrared Imaging detection is based on the infrared radiation energy measurement of the surface of the object oriented.Predictive maintenance test Predictive maintenance detection is the potential failure factors and pre detection diagnostic equipment, have the objective of maintenance work according to the plan. This maintenance test operation not only improve the reliability of equipment operation, and reduce maintenance costs and working time of equipment, reduce equipment Preparation of excessive maintenance problems. Infrared thermography technology also have non destructive detection, non-contact measurement, The intuitive observation, immunity to electromagnetic interference, quick measurement, high sensitivity characteristics, is the most effective predictive maintenance work.Abnormal equipment, usually show some signs, such as vibration, sound, electricity, light, temperature, pressure, different Measurement of other physical quantities, for finding and diagnosing the problem. Many equipment abnormal display may be in the early stage The temperature difference between the perceived, and infrared thermal imaging is a detection method of measuring temperature, thermal image and temperature will be measured Value according to the structure and properties of the device, to discover and diagnose problems, suggestions of improvement scheme.

Infrared LED lighting
The sensor was measured by the physical properties of the infrared. Infrared called infrared light, it has the reflection, refraction, scattering, interference, absorption properties. Any matter, so long as it has a certain temperature (more high than above absolute zero), can the infrared radiation. Infrared sensor measurement is not in direct contact with the measured object, so there is no friction, and has high sensitivity, fast response etc.. Infrared sensor comprises an optical system, a detection element and a conversion circuit. According to the structure of optical system can be divided into transmission type and reflection type two class. The detecting element according to the working principle can be divided into thermal detection device and the photoelectric detection component. The most widely used thermal element is a thermistor. Thermistor increase in temperature. the resistance to change, through the conversion into electrical signal output. Photodetector element commonly used is photosensitive element, usually made of lead sulfide, lead selenide, indium arsenide, arsenic, antimony, mercury cadmium telluride ternary alloys, germanium and silicon doped with other materials.Infrared sensors are commonly used in the non-contact temperature measurement, gas component analysis and nondestructive testing, is widely used in medical, military, space technology and environmental engineering. Such as the use of thermography infrared sensor distance measuring surface temperature of human body, can be found the temperature abnormal locations, timely diagnosis and treatment of diseases (see thermal imager); to monitor the earth clouds using infrared sensors on a satellite weather forecast, can realize large range weather forecast; using infrared sensor can detect the overheat condition when plane running engine。The human eye can see the visible light wavelength from long to short arrangement, followed by red, orange, yellow, green, cyan, blue, purple. The red light in the wavelength range of 0.62 to 0.76μm。 violet wavelength range of 0.38 ~ 0.46μm。 more short than Violet light wavelength is ultraviolet . To broadly speaking more long than red light wavelength is infrared. the sensor components can be a physical or chemical change amount to facilitate use of the electrical signal. infrared sensors is one of them. With the development of modern science and technology, the application of the infrared sensor has been very widely, with some examples below, briefly introduce the application of the infrared sensor. The working principle and characteristics of electric application and infrared sensor is a passive pyroelectric infrared probe of the human body heat released: the general human have a constant body temperature, generally at 37 degrees, so it will send a specific wavelength of 10UM infrared,the Fresnel will detecting and gather source that human body infrared emission around 10UM . Infrared sensors are usually used in pyroelectric element,
this element will be break balance of electric charge when the infrared radiation temperature changes, outward release charge, to generate an alarm signal.

1) the probe to detect human body radiation as the goal. So the pyroelectric element is very sensitive to the wavelength of the infrared radiation of about 10UM.

2) To only sensitive to infrared radiation of the human body, in the face of it and usually covered with Finil filter specia, so that the interference environment controlled by a significant role.

3) passive infrared detector, the sensor includes two mutually connected in series or parallel to the pyroelectric element. And made two electric polarization in opposite directions, environmental background radiation almost has the same effect on two pyroelectric element, make its produce pyroelectric effects offset each other, so no detector signal output.

4) once one intrusion detection area, human infrared radiation through partial mirror focusing, and the pyroelectric element is received, but two pyroelectric element received different heat, pyroelectric different, not offset by the signal processing and alarm.remote sensing as a large scope, high accuracy, quick access to information technology, will get more applications in the future technology development . Visible, sensors play a more and more important role in the field of science and technology, industrial and agricultural production and daily life. infrared sensors. As a part of them also will get larger development.
