Do LED panel lights, can changing the lamp beads improve the light efficiency?
1. Reducing the use current will linearly increase the luminous efficacy of the lamp beads, and the power will decrease accordingly.
If the current owner is using a 0.2W lamp bead, and replacing the 0.5W lamp bead with a larger chip package, the light efficiency will increase a lot. Costs will also increase.
If the landlord wants to calculate the lighting effect of the panel he designed, he needs to know the current used, the light effect of the lamp beads under the current, and the loss of each component.
If 0.5W is not high enough, and you are worried about the power drop, you can also use two-chip packaged lamp beads. For a design with high light efficiency, the higher the light efficiency, the higher the cost, which is not necessarily proportional.
2. In addition to changing the lamp beads with high luminous efficiency, reduce the driving current of the lamp beads,
It may also improve the overall light efficiency!
3. Consider three aspects:
(1) Lamp beads, it has been explained clearly upstairs. Using high-power lamp beads and reducing the current can increase the light efficiency, but at the same time, the cost will increase accordingly;
(2) Power supply, what is the efficiency of the existing power supply under your test? For the same parameters, if you use a power supply with 85% efficiency and a power supply with 90% efficiency, the light efficiency is naturally the latter higher;
(3) Structural materials, there are two pieces here, one is the light transmittance of your acrylic light guide plate, and the other is the reflectivity of your back reflective paper; the actual operating space that can be improved here is not large, because the panel light kit is a manufacturer’s match, so it can basically be ruled out.
