Description

TECHNICAL FIELD

[0001] The utility model relates to printing equipment technical field, concretely relates to a cooling constant temperature mechanism based on LED lamp pearl exposure heat dissipation. BACKGROUND

[0002] The present stage soft printing plate mainly is based on the photosensitive resin plate, and the exposure process of the soft printing plate is based on the characteristics of the photopolymerization photosensitive resin: the unexposed resin is in the semi-fluid state, after ultraviolet (UV) irradiation, the photoinitiator decomposes to produce free radicals, initiates the resin molecular crosslinking and curing, forms solid state graphic part, the unexposed part is removed through solvent dissolution, and finally forms the relief structure.

[0003] The exposure of the soft printing plate includes main exposure and back exposure, the main exposure: UV light penetrates the black coating of graphic area, initiates the crosslinking reaction of photosensitive resin, and is cured to form raised graphic, and the non-graphic area is not cured due to the shielding of the black coating, and is removed by subsequent solvent plate washing. Back exposure: the bottom base of the plate material is pre-exposed by the UV lamp, and the bottom layer resin is cured to enhance the relief support force, and the thickness of the bottom base is determined. This process needs to accurately control the energy (exposure time or power) to avoid the bottom base being too thick or too thin.

[0004] And the light source of the exposure of the soft printing plate is mainly derived from the conversion of LED lamp pearl from electric energy to light energy, and the core of the LED lamp pearl is PN junction, when the current passes, the electron and hole recombine to release light energy, but about 60%-70% of the electric energy is converted into heat energy. Although the overall electric-light conversion efficiency of LED is higher than that of incandescent lamp (up to 30%-40%), but the heat density of unit area is higher, especially for high-power LED lamp pearl, the heat released in a short time may cause the chip to overheat.

[0005] The light intensity decreases by about 1% when the temperature of LED junction increases by 1℃. If the temperature exceeds 70℃, it will accelerate the light decay and even burn the chip, affecting the service life of the LED lamp pearl. The exposure process of the soft printing plate needs thousands of lamp pearls to be integrated to irradiate, and a large amount of heat will be generated when the lamp pearls are turned on, which affects the service life of the circuit board and the lamp pearl. The market mainly uses aluminum-based / ceramic composite circuit board and fin heat sink to increase the heat dissipation area, and accelerates the air circulation through the fan or the heat dissipation hole.
