  • Brief Talk about the Difference between UV Lamp and LED Lamp




    To understand the difference between UV lamp and LED lamp, we can compare some phenomena in the process of using them.




    The essential difference between natural way UV lamp and LED lamp.




    So what's the difference between a UV lamp and an LED lamp?




    The following by the UVLED lamp manufacturers for your analysis






    First of all, let's look at some problems and reasons in the use of UV lamps.




    The following problems and reasons often occur in the traditional UV lamp of LED lamp curing machine.




    First, what is the reason for the fog of UV lamp? If there is mist in the tube, it is:




    (1) The problem of quartz pipes is that dehydroxylation is not good.




    (2) or bad exhaust during production.




    (3) The purity of the filled gas is not enough. If there is mist outside the tube, the volatile gas of ink and light oil is attached to the wall of the tube.




    It can be rubbed regularly with alcohol and other solvents.




    Second, the main causes of the deformation of UV lamp, what adverse reactions are there after the deformation?




    The main reason for the deformation of UV lamp is that the temperature is too high, slight deformation does not affect the normal use, but the life will be shortened a lot.




    Serious deformation will make the wall of one side of the lamp tube thinner and crack.




    Check whether the fan is damaged or the exhaust duct is too long, resulting in poor ventilation.




    3. What's the matter with the crystal adsorption in the UV lamp?




    In the process of making UV lamp, quartz pipe is not clean and has impurities.




    4. What happens when the UV lamp deforms into a bubble and bursts?




    If the local temperature is too high or the quartz tube wall is too thin, check whether the exhaust system is smooth.






    5. What is the reason why the metal head of the UV lamp always melts and burns down?




    (a) Metal lamp holder for a long time, copper frame oxidation, poor local contact caused by excessive current, ignition caused melting.




    B) The melting of the new lamp is due to the poor contact between the metal head of the UV lamp and the lamp holder, which results in the melting of the lightning.




    Check whether the copper contacts of the lamp holder are oxidized and whether the spring is elastic.




    6. What's the reason why the UV lamp can't be lit after several hours'use (the lamp is intact)?




    If it is metal halide lamp, it is because the halide ratio is not appropriate, or the output of transformer is too low, or the tube pressure of lamp is too high.




    If it is mercury lamp, it may be the reason of the electrode or the internal quality problem of the lamp, or the lamp has leaked.




    7. What is the problem of blackening at both ends of the UV lamp?




    It is the powders of the electrodes that peel off and adhere to the wall of the pipe, but the service life is normal.




    When it takes one to two hundred hours, this is not normal.




    8. What is the reason for the sudden burst of UV lamp in use?




    A) Excessive current (e.g. short circuit of capacitive lines)




    B) When the wind is sucked, something dirty hits the wall of the pipe.






    C) poor sealing of electrodes such as molybdenum and platinum.






    9. What happens when the UV lamp is always in use because of pressure drop and no recovery?




    A) Excessive exhaust




    B) The temperature of the cold end electrode does not rise.




    C) The electrical parameters of transformer, capacitor and lamp are not matched.




    D) The output voltage of transformer is too low because of the low network voltage. 10. After using the UV lamp for 300 - 00 hours, why do the fingerprints appear on the wall of the tube?




    A) This phenomenon occurs when the lamp wall is touched by hand during installation.




    B) When the inside of the wall is used as a lamp, the quartz tube is not clean enough.




    11. The current and voltage of the UV lamp are normal, but the illumination is abnormal and the dim is green and yellow. What is the reason?




    (1) The lamp power parameters are not correct.




    (2) There is slow leakage in the lamp tube.




    (3) The exhaust of the lamp tube is not clean when it is made.




    (4) The transformer is small.




    12. The first time the UV lamp can be turned on and off normally, but what happens when it can't be turned on again?




    If the capacitor and transformer are in good condition, and the line is smooth, there is no bad contact (there is voltage at both ends of the lamp)




    It is the problem of the lamp itself, usually the electrode problem, or the lamp has leaked.






    These are some of the problems that often occur in UV lamps, and then look at how LED lights are.




    LED advantages




    The inherent characteristics of LED determine that it is the most ideal light source to replace the traditional light source, and it has a wide range of uses.




    I. Small size




    LED is basically a very small chip encapsulated in epoxy resin, so it's very small and very light.




    II. Low Power Consumption




    The power consumption of LED is quite low. Generally speaking, the working voltage of LED is 2 - 3. V.




    The working current is 0.02-0.03 A. That is to say, it consumes no more than 0.1 W of electricity.




    3. Long service life




    Under the appropriate current and voltage, the lifetime of LED can reach 100000 hours.






    4. High brightness and low calorific value




    LED uses cold luminescence technology, and its calorific value is much lower than that of ordinary lighting fixtures.




    Five, environmental protection




    LED is made of non-toxic materials, unlike fluorescent lamps containing silver, which can cause pollution, while LED can also be recycled.




    6. Strong and durable




    LED is fully encapsulated in epoxy resin, which is stronger than light bulbs and fluorescent tubes.




    There is no loose part in the lamp body, which makes the LED not easily damaged.




    High energy-saving LED lamps: energy-saving and pollution-free means environmental protection.




    DC drive, ultra-low power (single transistor 0.03-0.0 watt) electro-optic power conversion is close to 1 100%.




    The same lighting effect saves more than 0% energy than the traditional light source.






    Long life: LED light source is called longevity lamp, which means never-extinguishing lamp.




    Solid cold light source, epoxy resin package, there is no loose part in the lamp body, there are no shortcomings of filament light burning, thermal deposition, light decay and so on.




    The service life can reach 10,000 to 1,000,000 hours, which is more than 10 times longer than that of traditional light sources.




    Shortcomings of LED Lamps: High Price and Light
