Embodiment 1

[0034] Such as figure 1 and figure 2 As shown, the embodiment of the present invention provides an LED light aggregation device, including an LED light source, a first lens, a second lens, and a third lens; the first lens, the second lens, and the third lens are arranged in sequence and are located on the same central axis Above, the LED light source faces the first lens, so that the scattered light emitted by the LED light source passes through the first lens, the second lens and the third lens in sequence and becomes uniform parallel light.

[0035]The LED light aggregation device provided by the embodiment of the present invention includes an LED light source and a first lens, a second lens, and a third lens with a light-condensing function; wherein, the first lens, the second lens, and the third lens are arranged at intervals in sequence and Located on the same central axis, the light emitted by the LED light source passes through the first lens, the second lens and the ...

Embodiment 2

[0056] An embodiment of the present invention provides a parallel exposure machine, comprising a plurality of LED light aggregation devices as described above, the plurality of LED light aggregation devices are arranged side by side with each other, and the central axes of the LED light aggregation devices are parallel to each other set up.

[0057] The parallel exposure machine provided by the embodiment of the present invention includes a plurality of LED light aggregation devices described above, wherein the plurality of LED light aggregation devices are closely spaced, and the central axis of each LED light aggregation device is parallel to each other. A parallel light beam can form the total light source of the parallel exposure machine. At this time, projections of different shapes or areas can be formed according to the number and rehearsal method of adjusting the light aggregation devices of LEDs, so as to meet the requirements of exposure machines of different specifi...

Abstract

The invention provides an LED light concentration device and a parallel exposure machine and relates to the technical field of exposure machines. The LED light concentration device comprises an LED light source, a first lens, a second lens and a third lens, wherein the first lens, the second lens and the third lens are arranged sequentially and located on the same central axis; the LED light source faces the first lens, scattered light emitted by the LED light source passes through the first lens, the second lens and the third lens sequentially to become uniform parallel light. The technical problem that an LED cannot be applied to the exposure machine due to the fact that light emitted by the LED is scattered in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of exposure machines, in particular to an LED light polymerization device and a parallel exposure machine. Background technique [0002] The exposure machine is mainly used in PCB circuit board manufacturing, LCD screen exposure, semiconductor production and high-precision fine line exposure. The exposure spectrum of the traditional exposure machine is mainly in the ultraviolet region, such as 365nm or 420nm. The light source used is a mercury lamp, and the ultraviolet spectrum is obtained by filtering. Because the mercury lamp starts slowly and the opening and closing affect the life of the bulb, it must be lit all the time during work. The life of the mercury lamp is 800 to 3000 hours and the power of the mercury lamp is generally several hundred watts to thousands of watts, which not only causes unnecessary power consumption but also The working life of the mercury lamp is shortened. Mercury lamps also ...
