选择灯泡都会考虑瓦数，灯泡瓦数越大光线越亮吗？今日就由PChouse为你一一解答。

 

When choosing a light bulb, the wattage is taken into account. Is the greater the wattage, the brighter the light? Today, pchouse will answer for you one by one.

 

 

 

不一定，要视具体情况而定。

 

Not necessarily. It depends on the situation.

 

 

1、在不同种灯泡中，由于做功效率不一样，比如LED节能灯效率远高于白炽灯，6w的LED灯可能比25w白炽灯更亮。

 

1. In different kinds of bulbs, due to the different efficiency, for example, the efficiency of LED energy-saving lamp is much higher than that of incandescent lamp, and 6W LED lamp may be brighter than 25W incandescent lamp.

 

 

 

2、供电电压与灯泡额定电压一致时，灯泡的功率越大灯泡才越亮。

 

2. When the supply voltage is consistent with the rated voltage of the bulb, the greater the power of the bulb, the brighter the bulb will be.

 

 

 

3、如果供电电压不一致时，灯泡的实在功率就不等于灯泡的标称功率了。比如：一个12v10w的灯泡，与一个6v5w的灯泡，用6v供电则后者的亮度更大。

 

3. If the supply voltage is inconsistent, the actual power of the bulb is not equal to the nominal power of the bulb. For example: a 12V10W light bulb and a 6v5w bulb with 6V power supply will have greater brightness.

 

 

 

4、如果有时电压很低，60w的灯泡未能达到额定状态，那么额定状态下的40w的灯泡就有可能更亮。

 

4. If sometimes the voltage is very low and a 60W bulb fails to reach the rated state, then a 40W bulb at rated state may be brighter.
