When purchasing an dental LED light curing machine, you should pay attention to the problem of LED overheating and light intensity decreasing too fast with time. This is actually a heat problem of LED. In order to obtain the large light energy output of the LED, the driving current of the LED must be increased as much as possible, but if the driving current is too large, the LED will generate serious heat, which will greatly shorten the service life of the LED and even burn the LED. When purchasing, it can be tested from two aspects.
First, after working in continuous strong light mode for 10 seconds, touch the shell near the LED of the curing machine for a few seconds, so as not to feel hot. Of course, when testing the machine, you should avoid making the machine emit strong light for a long time in succession, so as to prevent the LED from overheating and being damaged.
Second is to test the change of light intensity over time, let the curing machine work in continuous strong light mode, the light intensity at the beginning of the test work and the light intensity at 10 seconds of work, the less the light intensity decreases, the better, the difference between the two It is appropriate not to exceed 10%.
Dental light curing generally consists of: the light curing lamp is composed of a handle, a charging base, a hood, an isolation sleeve, a test block, an optical lens, a power plug and a power adapter.

In life, people are often exposed to large or small diseases. How do we go to the hospital to infer the diagnosis of the disease? There are no more than two ways: First, the doctor has observed and confirmed the cause of the disease after the patient's description. 2. Find out the cause of the disease through the images obtained by the X-ray film. Whenever some patients hear about taking X-rays, they will not only think "Is there radiation from X-rays?" Let’s find out today whether the radiation dose of X-ray machines will cause harm to the body.
The radiation dose of dental radiographs used in dental clinics is small, the radiation dose is about 5 microsieverts, and the radiation dose of chest radiographs is about 20 microsieverts. After all, how big is this radiation amount? Let's roughly estimate that each of us in this world is in radiation at all times. According to the International Commission on Radiological Protection, the radiation limit of the general population is not more than 5 millisieverts per person per year [(mSv), which is equivalent to 5000 microsieverts (uSv)]. Generally, the radiation dose that a person receives per year is about 4 millisieverts, which is a small dose and a safe dose. About 85% of the radiation comes from the environment in which we live (in nature), and only 15% comes from medical examinations. Even if you sleep in a bed with others, you will be exposed to radiation from the body of others, about 0.05 microsieverts. Even if you prefer independence, the annual radiation dose of potassium in your body is about 390 microsieverts.
In other words, the radiation dose of watching a computer, TV or mobile phone is about 1 microsievert a year. If you eat a banana, the radiation dose is about 0.1 microsievert. If you spend a day in a radiation area that is above the equilibrium level, such as the Qinghai-Tibet Plateau, the radiation dose is about 1.2 microsieverts. Estimated by smoking two packs of cigarettes a day, the radionuclide radiation dose in cigarette tobacco is equivalent to taking a chest X-ray once a day. So we don’t have to worry about the X-ray radiation taken in the hospital.
