The camera’s service life is more than 10 years, whether the infrared lamp life can reach this level(10 years)? Get the correct answer before. First you must understand the infrared lamp manufacturing principle At present, there are mainly three kinds of infrared lamp manufacturing model:1, halogen lamp: 2, multi chip LED, 3, Single chip LED. Halogen lamp is a traditional technology, high energy consumption, high quantity of heat, short service life, because of its low efficiency, evaluation Meter will gradually fade out of the IR LED market.Multi chip LED also has two kinds of forms, one kind is contains 4 to 8 LED chips; another is the array type light-emitting chip, containing 10 to 30 LED chips Why do the chip? Some theory from manufacturers: infrared lamp irradiation distance is not enough because the energy is not enough, more chip set Together, of course, energy is high, the farther the distance requires more energy,But the camera not can receive all infrared lighting.Multi chip LED due to inherent shortcomings of structure that does not light focus, emitting optical system is not reasonable, useful optical efficiency is relatively low (However, several times stronger than halogen lamps), its advantage is not effectively play out. For example, the array type LED, current up to 1000mA above, basically only A penny coin size, heat dissipation becomes a problem. LED is most afraid of fever, At the same time, multi chip LED Production requirements are very strict, each chip can have a little difference in performance, or a chip broken will be draw all finished Overall,compared with the single chip LED, multi chip LED service life is not enough Single chip LED has the advantages of simple production process, quality easy to guarantee, low heat, light emitting optical system is reasonable, In theory Single chip LED is the ideal device as the infrared lamp, the service life can reach more than 100000 hours. So, Is it right? All single chip LED lamp life is very good?

In fact, the answer is inaccurate. Are there were many reasons for this, such as some LED chip level is very low, high impurity; some production Technology doesn’t pass, leakage phenomenon; some super power use, rated at 20mA, but the use of 50mA or above; have no protection circuit, or the circuit design unreasonable, all these will lead to single chip LED of infrared light fast broken.

If you want to ensure that the infrared lamp service life,
First to choice the LED chip of high grade，High grade chips with high power and good consistency, luminous efficiency High heat is very small, a higher level quality of LED is 10 times than normal LED quality，of course, the price is very expensive.
Secondly, the optical system design Meter should be reasonable, luminous uniformity, higher utilization rate, heat dissipation is faster.

Third, we must strictly control the working voltage. LED is very sensitive to voltage, LED tube core will be burned when Voltage slightly higher; and the voltage slightly low luminous quantity will be greatly reduced. The best matching switch power supply of high quality, AC transmission Into the best voltage from 170 Volts to 270 volts can do better regulated power supply, suitable for harsh environment.

Fourth, the input power supply line selection of resistant high / low temperature is Good, and super soft bending. There is a manufacturer of infrared lamp and input power line can be work at 60 degrees below zero and high Temperature 250 degrees above, this product is worthy of trust.

  The putting forward of the problem
In general, at least in the 1W above call high-power LED power。The 1W, 3W, 5W, 8W and 10W is common on currently，Which is known as the “green light”, is moved to new development direction that a large current (300mA ~ 1.4A), high efficiency (60 ~ 120lm / W), adjustable brightness。However, the LED current is determined the luminous intensity of high power LED。LED current is too strong will cause the LED lighting is too weak, the current is too weak will affect LED luminous intensity,and therefore need to provide constant current LED driver power to ensure power safety LED use, but also need to meet the expectations brightness requirements, and ensure that each the LED brightness, color consistency. So, traditionally used to drive the bulb (tungsten wire), power fluorescent lamps, energy saving lamps, sodium lamps and other light sources are not suitable for direct drive high power LED. LED Driven by mains power supply also need to address the buck, isolation, PFC (power factor correction) and constant current problem, need a higher conversion efficiency. Currently, there are thousands of models dedicated high-power LED constant current driver chip on the market, Most adopt a dedicated hysteretic converters of chip, low voltage input range, boost, buck can, PWM control, power switch can be internal or external, the output current can reach 1.5A, the built-in overvoltage, undervoltage, open / short and temperature protection circuit.

Herein head light heat is too high, heat dissipation requirements are quite high, operation process a lot of problems.so many users are very headache. Another problem is light failure (lighting loose)，large power consumption and high cost of replacing the light source, resulting in the technical requirements are also high up for manufacturers in the production. with low-cost to induced ignorance customer of manufacturers that production of substandard products and no technical force。Appears in engineering problems frequently。
Here would like to thank The LED manufacturers in domestic, The LED manufacturers created a precedent in this LED industry, make high power head light with single LED COB. If we do not error in our memory, the first head light with 3PCS 3W lamp is the so-called 15W LED small head. In the conditions of superiority, soon other LED manufacturers imitation of that product is perfect. So many LED manufacturers will benefit from this product, so this is not only our domestic lamp pride, we have to thank the very visionary boss of LED manufacturers。LED single chip high power head light now has 27W lamp, 50W lamp beads 3 prism effect,
80W 100W 5 lamp beads 5 prism effect. The 100W lamp can be ultra conventional 250, compared with the conventional 575. But the color temperature of LED and conventional lamp everybody should know, if the color temperature requirements is demanding we suggest that still continue to choose the regular lamp。Because this is fundamentally different.At present, many of our customers in some places slow shark bar using our LED head spotlight 30W and 50W, the time has been more than half a year, Giving satisfaction sufficient to meet a demand form the customer at present。Because the main purpose is to help them solve the problem after service。 The need to replace the light source, power of temperature is small, the failure rate is very low. But these customers also reflects some problems, long life, light a long time can be used, their business may be affected. Because this lamp has the advantages of low cost, long service life at present, use a year without a problem, maintenance costs can buy a conventional head light. The use of time longer, in this way ，work not easily for retail business.

LED light source products will become the substitute of green energy, the continuous innovation of product development, and has the advantages of smaller volume, higher efficiency, the greater the wattage, the lower the price will become the future trend of LED development。And can meet the requirements above。In recent years, due to the global energy consumption and environmental deterioration, countries rising awareness of environmental protection, have been putting forward proposals to ban incandescent bulbs and other policies. LED lighting products become the alternative green energy, in constant innovation in product development, while smaller, more efficient, the greater the wattage, the lower the price will become the future trend LED. Some of the limitations of the traditional materials development, but in recent years the ceramic substrate package, launched a broader advantage, making the development of LED, can meet the above requirements.

A 、What are the application advantage of ceramic substrate?

On white lighting models, available now 110lm / w of the products, other plane of the light source can also provide international companies with comparable products in the series the.

B, High-Brightness LED Future Trends Beginning in 2009, beginning of concern that LED lighting source products。due to energy saving, high efficiency, mercury-free, long life … and other characteristics, and gradually began to flourish, and various concerns, so in 2010，some manufacturers have added lighting the ranks of the application of LED。Looking to 2013, in the world, including the United States, China, Korea, Taiwan … etc., are committed to accelerate national and industry standards, making poor physical LED manufacturers will face the fate of the closure and consolidation, which will increase the relative consumer confidence (including governments, businesses and consumers in general), after 2014, LED lighting will be price, quality and efficiency reaches a certain level,
so that the demand of LED will be quickly grow up.

LED packaging form divide of separation and integration。LED separation device belongs to the traditional form of packaging, widely used in various related fields, after nearly forty years of development, has formed a series of mainstream product form. The LED COB module  belongs to the personalized packaging forms, mainly for the application of some cases and personalized product design and production, has not formed the mainstream form ofproducts.Semiconductor lighting to enter the general lighting field, the cost of production is the first major constraints. To reduce the cost of semiconductor lighting, we must first consider how to reduce the cost of the LED package. The traditional approach is LED lighting: LED light source module separation devices → MCPCB lighting module→ LED lamps, mainly based on the core source components do not apply and the approach is not only time-consuming work, and high costs. In fact, we can be “LED light source module separation devices → MCPCB lighting module” combined the MCPCB lighting module and LED chips together to make COB light source module direct, take the “COB light source module → LED lamps” route, not only can save time, but it will save the cost of the device package. The cost, compared with the separation light source device, COB light source module can save device packaging costs in lighting product applications。light engine module production cost and the secondary light distribution costs.In the same function lighting system, the overall cost can be reduced about 30%, which is for the promotion of semiconductor lighting applications has great significance. In performance, through rational design and molding microlenses, COB light source module can be effectively avoided discrete light source device present in combination in the light, glare and other disadvantages, but also by adding an appropriate red-chip combination, without reducing the light efficiency and life under the premise of effectively improving the color of the light source (now can do 90 or more).
