How to change the night light of the watch, what to do if the night light on the watch is gone

If you want to change the luminous glow of the watch, you can only change the dial and hands.

1. The luminous material of the watch generally has a certain radioactivity, such as: radium, tritium, phosphor, etc., it has a half-life, and the luminous effect will slowly weaken with the passage of time. Moreover, these substances are generally applied to the dial and hands.

Therefore, if you want to change the luminous glow of the watch, you can only change the dial and hands.

2. Although the luminous material of the watch is traced, it will also bring some adverse effects to people to a greater or lesser extent. Therefore, it is advisable not to sleep with the watch on.

The watch is coated with a light-storing fluorescent. Radioactive substances need to absorb and reserve sufficient intensity of external light in advance to transition their own electrons from low energy levels to high energy levels and store them. When the surrounding environment is dark, it gradually and slowly releases the absorbed energy, and the electrons transition from high to low energy levels, and the fluorescent agent begins to emit light.

Since the light storage type itself does not carry the ray excitation material, the afterglow durability is temporarily inferior to that of the self-luminous type. (Self-luminous fluorescent agents mostly excite fluorescent agents by releasing rays from trace amounts of radioactive substances carried by themselves).

Dear, hello, I am glad to answer for you that the luminous light of the watch is generally applied to the hand and dial with a phosphor (liquid) and emit luminous light. Regardless of the battery, the watch does not emit luminescence, which may be due to the absence of phosphor or phosphor liquid. Workaround:

1. You can go to a special maintenance center to make up for the night light; 2. You can try to keep the watch illuminated in the sun or light for a period of time, and the glow-in-the-dark effect will be enhanced; 3. If the above methods fail to solve the problem, you can only replace the watch. I hope my answer is helpful to you.

Use your hand to quickly shine a flashlight on the surface to replenish the light source.

There are two types of luminous materials: self-luminous type and phosphorescent type. The basic composition of the self-luminous luminous material is a radioactive material, which does not need to absorb energy from the outside and can continue to emit light.

Phosphorescent luminous materials rarely contain radioactive substances, there is no restriction on use, and it can only emit light by absorbing external light energy, and it is necessary to reserve enough light energy to ensure that it has been emitting light. Another drawback of luminescent luminous materials is insufficient brightness. The luminous glow of most watches is painted with tritium.

Because glow-in-the-dark needs to be seen in a very dark place, when someone asks you "do you want to see my glow-in-the-dark watch", it means "do you want to come to my bed".

Legend has it that this meme first came out of a joke:

A boy calls his girlfriend to come to the house, and the girl shyly prepares everything. As a result, the boy called the girl into the bed and said, "Show you my newly bought glow-in-the-dark watch."

The luminous light of the watch will not be permanently bright, the luminous light of the watch can generally be maintained for 3-5 years, and the main material used for the current luminous is tritium, which is much less harmful to the human body than radium, and can be ignored under normal circumstances.

Tritium (pronounced 'chuān'), English name: tritium, also known as super heavy hydrogen, is one of the isotopes of hydrogen, and the element symbol is t or 3h. Its nucleus is composed of one proton and two neutrons, is radioactive, decays, has a half-life of years, and is atomic weight.
