LED due to have long service life, brightness large, save the features such as electric energy, environmentally friendly and applied range, the market share that it is occupied in illumination market is increasing.But along with in the use procedure of LED, the heat dissipation problem of LED lamp, and LED light declines, becomes the key factor that a restriction LED service life and LED apply.Especially in high-powered LED lamp, input power only has the electric energy conversion of 15% ~ 20% to be that luminous energy exports, and all the other then convert heat energy to, if these heats fail to discharge the external world in good time, the luminous efficiency of light fixture not only can be made to reduce, and LED chip Yin Wendu may be caused too high and lost efficacy rapidly.
In order to solve the heat dissipation problem of LED illumination device, more common method is in LED lamp, install heat conduction or heat abstractor.Such as, radiator fan, radiating fin are set in LED lamp; Or conducting-heat elements is set in LED-baseplate.But when the heat conduction constantly LED lamp produced along with heat abstractor or heat conducting element is to surrounding environment, the temperature of surrounding environment can constantly raise.And along with the continuous rising of environment temperature, heat radiation or the heat conductivility of heat abstractor or heat conducting element decline gradually.Only have when environment temperature declines naturally, heat conducting element or heat abstractor could continue the heat distributing LED generation.Therefore, this LED lamp being provided with common heat abstractor still exists because local temperature is too high, heat cannot be got rid of, and produces the defect that illumination intensity declines, service life shortens.
Utility model content
In order to overcome existing heat abstractor defect influenced by ambient temperature, the utility model provides a kind of not influenced by ambient temperature and can reduce the LED heat abstractor of environment temperature.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of LED heat abstractor, comprise metal shell, the cooling-cycle device being connected with it and arranging is provided with in described metal shell, described cooling-cycle device comprises cycle condenser, the feed tube of described cycle condenser is all connected with refrigerator with drain pipe, circulating pump is provided with in described refrigerator, the section of tubing of described cycle condenser is arranged at the inside of cold plate, described cold plate is provided with LED light module, and described LED light module is provided with at least one LED light source.
LED heat abstractor described in the utility model, is particularly useful for the large-scale or medium-sized LED illumination device that the comparatively large and needs of power work long hours.
LED heat abstractor described in the utility model, realizes cooling and the circulation of the refrigerating fluid in cycle condenser by being arranged at refrigerator in metal shell and the circulating pump be arranged in refrigerator.In actual use, the refrigerating fluid circulated is while the heat exchanging LED light module generation, and the heat in all right switching part environment, accelerates the heat diffusion of LED light module then further.
As preferably, described cold plate is made up of heat-conducting plate and thermal insulation board, and described LED light module is arranged on heat-conducting plate.Wherein, the setting of heat-conducting plate on cold plate, fast and effeciently can realize the transmission of heat to refrigeration piping in cold plate of LED light module generation.
As preferably, described cycle condenser is provided with flow control valve.In actual use, can according to the power of LED light module, regulating flow control valve.
As preferably, described thermal insulation board is made up of polystyrene plastics.Polystyrene plastics is a kind of heat-barrier material of heat conductivility difference.Wherein, the setting of described dividing plate plate, can reduce the transmission of heat towards periphery in environment that LED light module produces.And then the object that arranges of described thermal insulation board is; The heat production of LED light module is made to realize diffusion by cycle condenser as far as possible.
As preferably, described metal shell is provided with the transparent lamp shade corresponding with LED light source.
The utility model compared with the existing technology has the following advantages and effect:
1, LED heat abstractor described in the utility model is by arranging cycle condenser, refrigerator and circulating pump, while realization reduces LED light module chip temperature, also reduce the temperature of environment, then effectively overcome the defect that the heat dispersion of heat abstractor in existing LED illumination device is influenced by ambient temperature.
2, LED heat abstractor described in the utility model, while the radiating efficiency improving existing large-scale or medium-sized LED illumination device, effectively improves short and luminous efficiency in service life of existing large-scale or medium-sized LED illumination device
