Basically there is no color issue in the single LED applications, but the color issues many be obvious when the multiple LEDs are put into use at the same time. Firstly, take a look at a group of lamps and check whether the lights colors are inconsistent, then the quality of the led tube lighting is not in the high level.
The problem of LED insulation
The insulation refers to the heat dissipation substrate to the positive and negative of the LED, and this is the fundamental problem which is unresolved currently, only taking use of the remedial measures, such as taking use of the aluminum substrate to deal with insulation (the initial aluminum plate is not insulated, and now almost all do) and we may find incomprehensible. The single insulated LED has little effect while a large number of LEDs in series are affecting a lot.
The problem of LED anti-pulse
This problem is still controversial in theled tube light manufacturers, but it does exist in the practical application, and the main reaction is on the cold pulse, and a small number of LEDs are breakdown or disconnected in the cold state, instead of the electrical instantaneous nor the electrostatic or high pressure ( boot voltage is within range).
The potentially blinding risks in LED
LED light points are too concentrated to the super brightness of the center point, so it is easy to hurt the eyes of the people. Although some lighting manufacturers have make efforts in this regard, because the lagging of regulatory, it only depends on man's moral.
LED light-emitting angle
Due to the LED lens package of various manufacturers are not the same, even the same emitting angle (nominal angle), the effect is not the same, making the selection of poly mask even more difficult, and still not universal.
LED brightness is insufficient
The insufficient brightness makes the LED light can only play a supporting role in the lighting industry, and is mainly used for decoration.
LED heat problem
In theory, the LED does not give out too much heat, but due to the immaturity of the technology, the LED is well-known for its heating.
LED efficiency is low (light emitting rate)
At present, the LED electric conversion efficiency is too low (because there is no device to test, and the detail information has not been given).
LED light fades and life
The light fades and life of LED produced by the Mainland or Taiwanese is more serious, the matching of LED driver may affect the light fades and life of LED.
www.ervan.cn has a strong engineer team which composed of 16 individuals with perfect designers. Our management system is strictly conducted according to ISO9001-2008 standard. Our led tubes, including t8 tubes and t10 tubes, are qualified with TUV/CE/RoHS/FCC and UL certificate.
