Description

A kind of heat radiation module of ultraviolet light polymerization make-up machine

Technical field

The utility model relates to a kind of heat radiation module of ultraviolet light polymerization make-up machine.

Background technology

LED is little with its volume, and is all solid state, the long-life, and environmental protection, series of advantages such as power saving are used widely in each big field, become one of high-tech sector of tool development prospect of 21 century.Numerous countries such as the U.S., European Union, Japan launch respectively plan, drop into huge fund and quicken its development, to capture the energy strategy commanding elevation.The electro-optical efficiency of existing LED is about 20%～30%, and 70%～80% energy is converted into the heat energy that can't discharge by radiation.If package cooling is bad, chip temperature is raise, cause that stress distribution is uneven, chip light emitting efficient reduces, the fluorescent material conversion efficiency descends.When temperature surpasses certain value, it is soaring that the crash rate of device will be index law.

Ultraviolet light polymerization irradiation apparatus employing LED is that the ultraviolet ray of light source is shone UV resin (ink, sticker, coating), and resin is hardened rapidly, is usually used in industrial trades such as electronics, spraying, printing and dyeing.For example adopt this equipment that the UV resin that spreads upon on small

such as CD, MD, DVD player, lens, notebook computer liquid crystal panels is carried out cover, can realize accurate the combination.

In the ultraviolet light polymerization irradiation apparatus, the LED luminous tube is valuable electronic devices and components, and its changes of properties directly influences the work effect of equipment.Because current technical limitations, the thermal efficiency of the LED luminous tube in this equipment is not high.As be in the unlatching duty for a long time, and the LED luminous tube can be because of the accelerated ageing of being heated, and shorten service life.
