Precautions for the use of luminous dice: Put the dice in the sun to get a good luminous effect! The ideal luminous effect can also be achieved under the strong light. Special attention: the luminous effect can be generated repeatedly, that is to say, the luminous function of this dice will never disappear. Generally, the dice can be bright for 2-3 hours under the condition of fully absorbing light energy. The quality of the luminous effect depends on the brightness of the environment. The darker the environment, the better the luminous effect! Friendly reminder: This is a luminous dice, which means that luminous powder is added to the original material. The luminous dice is different from the LED light-emitting principle with batteries. It absorbs light energy by luminous powder and stores it (but it will not store For a long time, like some buyers say that I put it in the sun for a whole day during the day, but it doesn’t shine at night? Actually, the dice absorb and store light energy during the day, but they haven’t waited until night. , But it has been released. The correct use is to absorb light energy before use, and then emit light in the dark). After the dice uses up the stored energy, it needs to absorb light energy before it can emit light again. This way of recycling, I hope everyone I have learned a simple law of conservation of energy. If the dice is not connected to a power source or other energy, how can it emit light? Of course, it means that it needs to absorb a light source to emit light. So, those who buy things by imagination, please ask carefully and consider it. Then place an order, according to your own needs, according to the actual situation, whether this luminous dice is necessary or not, or you can search for the luminous principle of luminous powder on Baidu, please do not give a bad review at will, or complain about the dice after you buy it. Not bright, the effect is not good, the bright time is short, or the added luminous powder is insufficient, cutting corners, etc., such pros, please be optimistic about whether to buy before, we can only do this, please pros Don't make negative comments at will, thank you! !
