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.
