Analysis of the causes of common failures of LED clean panel lights by LED purification lamp manufacturers
Analysis of common fault phenomena of led purification lamps
1. After the LED purification panel light is lit, there will be a dark area around the light-emitting surface.
The dark area phenomenon of the LED purification lamp is generally the problem of the light guide plate. LED purification lamp manufacturers can find product material problems during the manufacturing process, so when the product leaves the factory, the LED purification panel lights pass the test. However, during the logistics and transportation, the purification lamps may be damaged. There is also a phenomenon that may lead to the dark area of the LED purification panel light, that is, if the frame of the LED purification panel light is too thin, and the worker tightens the screws too tightly when installing the purification light, the frame may be deformed and pressed against the light guide plate. Then a serious dark area phenomenon is formed in the vicinity.
2. The light of the LED clean panel light turns blue or yellow
The light emitted by the LED clean light is abnormal, which is a structural design defect of the clean light. Purification lamp manufacturers should first adjust the distance between the LED lamp beads and the light guide plate, or change 3T to 4T, because the refractive index of blue light and yellow light is different. If the problem cannot be solved, it may be the problem of the LED lamp beads, and the problem can be solved only by replacing the lamp beads.
3. The aluminum frame of the LED purification panel light has large seams
The frame seam of the LED clean panel light is too large, which not only affects the appearance, but also may cause light leakage. This situation is mostly due to the high defective rate of frame manufacturers, which leads to the problem of excessive frame gaps in some products.
4. The LED purification lamp has problems such as bright edges, bright spots and bright spots.
This problem is most likely caused by a problem with the light guide plate. The light guide points engraved by the light guide plate during production are an important channel for the refraction direction of the LED light, so it is very important to choose a good material supplier.
5. Water ripples appear after the purification LED panel light is lit
The water ripple phenomenon of LED clean lights is caused by current pulsation, and most of them can solve this problem by replacing the power supply.
6. The luminous flux measurement value of the LED purification panel light is too low
Use a distributed photometer to test at multiple points. If the luminous flux is too low, it means that it is a problem of material selection. Replacing the LED lamp beads with high luminous efficiency can improve the luminous flux of the LED purification panel light.
7. Other reasons for the failure of LED purification lights
The light guide plate of the LED purification panel light expands when it is heated, and then presses the lamp bead, and the light may appear bluish, dark area or even dead light.
