Abstract

The invention discloses an ultra-violet LED face light source for a PCB exposure machine. The ultra-violet LED face light source comprises a plurality of water-cooling type ultra-violet LED lamp box units, wherein each water-cooling type ultra-violet LED lamp box unit comprises M*N ultra-violet LED lamp beads arranged on an element installation face of a copper substrate and arranged into a matrix structure, all the ultra-violet LED lamp beads are in series connection, each ultra-violet LED lamp bead is covered with a reflection cup, all the reflection cups are arranged on a reflection cup installation plate, the reflection cup installation plate is connected with the element installation face of the copper substrate, a unit water tank is arranged on the water passing face, opposite to the element installation face, of the copper substrate, and a temperature controller is arranged on the unit water tank. The ultra-violet LED face light source for the PCB exposure machine is remarkable in energy-saving effect, large in exposure area, far in exposure distance and high in energy uniformity. The light source is stable and reliable, performance is far more superior than a traditional light source, is low in cost and free of pollution and radiation, and can completely replace the traditional light source.

Description

technical field [0001] The invention relates to an ultraviolet (UV) LED surface light source for a PCB (printed circuit board) exposure machine, belonging to the field of ultraviolet LED surface light sources. Background technique [0002] Traditional light sources used on PCB (printed circuit board) exposure machines mainly include capillary lamps, metal halide lamps, high-pressure mercury lamps, etc., and these traditional light sources each have corresponding characteristics. For example: capillary lamps have the advantages of good line exposure quality, but short life and easy to burst; metal halide lamps have the advantages of fast exposure speed, but are difficult to light, low efficiency, high heat, and short life; high-pressure mercury lamps rely on optical circuits It has the advantages of high exposure precision, but its optical circuit structure is complicated, the use cost is high, the maintenance cost is expensive, the service life is short, and it will generate...
