Hvordan identifisere kvaliteten på integrerte LED-panellys i taket
Sammenlignet med andre lamper har LED-lamper enestående fordeler: energisparing, lang levetid og grønn miljøvern. Kvaliteten på LED-lamper varierer imidlertid sterkt, og forbrukerne vet ikke hvordan de skal velge? I lys av den nåværende onde konkurransen i markedsprisen på flatpanellamper, har oppføringen av et stort antall substandard produkter (fagfolk kaller dem (underordnede varer, dårlige varer, dårlige varer) krenket den reelle verdien av LED-energisparing, lenge liv, miljøvern, etc. For å bruke LED-teknologi til feltet for integrerte tak, har det alvorlig påvirket den sunne utviklingen av integrerte LED-panellys i taket. Hvordan skille fordeler og ulemper med LED-lamper og lanterner bør starte fra følgende aspekter:
1. Look at the overall "power factor of the lamp": a low power factor means that the driving power supply and circuit design used are not good, which will greatly reduce the service life of the lamp. .
The power factor level can be detected with the "power factor meter"! Generally, the power factor of exported LED lamps is required to be above {{0}}.85. If the power factor is lower than 0.5, it should be said that unqualified products or waste products not only have a short lifespan, but also the actual power consumption is about twice as high as the nominal value. That is to say, compared with ordinary energy-saving lamps, it does not save electricity at all! So, this is why LED lamps need to be equipped with high-quality, high-efficiency drive power!
For consumers who do not have a "power factor meter", another method is to use an "ammeter" to detect two similar products with the same nominal power. The more you do not save electricity! At the same time, the current is unstable, which is not good for the life of the lamp bead and the life of the overall lamp!
2. Look at "lamp heat dissipation conditions - material and structure": LED lamp heat dissipation is also very important. Lamps with the same power factor and lamp beads of the same quality, if the heat dissipation conditions are not good, the lamp beads work at high temperature, and the light decay will be Very large, the lamp life will be reduced.
For tiden er de viktigste varmeavledningsmaterialene som brukes kobber, aluminium og PC. Platealuminium, bilaluminium (aluminiumsprofil, ekstrudert aluminium) er nummer to, støpt aluminium er det verste, og varmeavledningseffekten til innsatsaluminium er best!
3. Look at "lamp bead quality": lamp bead quality depends on chip quality and packaging technology.
