It is mainly related to three factors: 1. False power labeling of lamps. Some inferior LED lamps have inconsistent labeled power with the actual power, and the actual power is higher, which naturally increases power consumption; 2. Low luminous efficiency. High-quality LED lamps can reach a luminous efficiency of 100-150lm/W, while inferior lamps may be lower than 80lm/W. To achieve the same brightness, more electrical energy is required; 3. Low efficiency of the driving power supply. The drivin...
Prioritize troubleshooting three common problems: 1. Power supply problem: check whether the switch and socket are in good contact and whether the voltage is stable. If the voltage fluctuates too much, it will cause the lamp to flicker; 2. Driving power failure: the driving power supply is the "heart" of the LED lamp. Aging or damage will directly cause the lamp to go out or flicker. You can try replacing the driving power supply of the same specification; 3. Loose lamp wiring: open th...
This situation is called "light decay", which is a normal loss phenomenon of LED lamps. There are two main reasons: first, the heat generated by the long-term work of the LED chip accelerates the aging of the chip, leading to a decrease in luminous efficiency; second, the accumulation of dust inside the lamp blocks the light output. High-quality LED lamps have a slow light decay rate, and can still meet daily lighting needs after 5-8 years of normal use. Regular cleaning of lamp dust c...
No, it is not a quality problem. This is the "warm start" phenomenon of LED lamps. The LED chip needs a certain time to reach a stable working temperature, especially in a low-temperature environment. The brightness will be slightly low when starting. After the chip temperature stabilizes, the brightness will return to normal. It is a normal physical characteristic and does not affect the service life and use effect of the lamp.
