LED exposure machine is used for PCB manufacturing, semiconductor production and high-precision fine line exposure. LED exposure machine can also be divided into various types, including precision exposure machine, LED parallel exposure machine, energy-saving exposure machine, etc. The working principle of LED exposure machine is the same. Now let's take a look at the "LED exposure machine manufacturer" to tell you its working principle and characteristics.

1. Power saving, energy saving and cost reduction - When the LED reaches a certain brightness, only about 15 watts of energy will be consumed, while the traditional lamp will consume 1500 watts of energy to achieve the same brightness. Even compared with the UV halogen lamp, 80% of energy can be saved, so the LED lamp is very energy-saving and environmentally friendly.

2. Long service life - LED lamp life exceeds 20000 hours.

3. Wider application range - LED light emission is not infrared heating, and its heat release is low, so it will not affect the transmission of media (such as foam plastic plate, foil film, PVC, etc.) that are easy to be heated and deformed in the printing process. In this way, the application scope of media is more extensive.

4. Fast reaction (switching) time - LED light does not need to be preheated, and can be printed immediately after startup, thus improving productivity.

5. High safety - LED lamp has no UVC rays, no ozone release and is not easy to be damaged.

6. High stability - The printing quality of the UV ink-jet printer is closely related to the UV drying and curing process. The stability of the LED light makes the output energy predictable and stable, so the printing effect is also predictable and stable.

7. LED allows ink to be deeply solidified - LED light emits light with a wavelength of 395nm, which allows ink to be deeply solidified, so it will not occur when the surface of the printed matter is dry but the bottom layer is not. Printing on various media has strong adhesion and scratch resistance.
