Description
Technical field
The present invention relates to the irradiation light of single power 2800W of a kind of led light source
Technical background
Luminous second tube sheet, be called for short LED, have advantages such as the little energy consumption of volume is low, high brightness, long-life, low pressure operation, be widely used in each industrial circle, adopt LED semi-conductor solid-state light source replace incandescent and fluorescent lamp etc. to become trend, but LED is because of being subjected to the restriction of self-characteristic, the operating temperature rising can cause optical attenuation serious, influence service life, and the irradiation light of single power 2800W of a kind of led light source, more must better radiator structure of thermal diffusivity and cooling measure, the heat that is produced when better heat abstractor distributes led chip work.Existing single high-power LED illuminating lamp, usually with being to be bonded on the pedestal with elargol and a plurality of led chip, dispel the heat by substrate conduction heat, because the led chip dense arrangement is more concentrated together, the heat that gathers is difficult to derive, work can make the temperature of led chip surpass its temperature of limitting for a long time, and fluorescent material has influenced the illuminating effect and the service life of led light source at long high temperature.
Summary of the invention
The technical problem that will solve required for the present invention is to overcome the above-mentioned defective of prior art, provide a kind of high heat conductive metal substrate heat sink for the combined light source of single group power 140W, simultaneously 20 groups are installed in the taper gengon LED combined light source that radiator was provided with that the radiator structure performance is provided with vacuum cavity well and arrange on the seat and utilize in the vacuum cavity, add an amount of working solution, can be fast heat be transferred to principle on the diffusing sheet of entire radiator, low-temperature condition when keeping LED work, add and overlap a collector lens again, lens add a reflector outward again, it is good to make luminous intensity distribution, the irradiation light of single the power 2800W of being convenient to maintain of a kind of led light source.
The technical solution adopted in the present invention is, with monochromatic multiple chips array led chip, by series-parallel combination, surface silica gel adds the epoxy glue embedding of fluorescent material, comprise a plurality of led chip metal substrates, reflective groove cup, wiring board, wiring board bears down on one, gold thread, fluorescent material, silica gel and welding material, a plurality of led chips are electrically connected with wiring board, wiring board is electrically connected with constant-current source, metal substrate is made the heat sink combined light source that is packaged into single group power 140W, being combined in the taper polygon LED combined light source that the radiator of establishing vacuum cavity sets with 20 assembly arranges on the seat, there is the plane seat of 5 direction positions at described seat, arrange the combined light source of 4 groups of single group 140W on the plane seat of each direction, add collector lens of cover, the sheathed again outward reflector of collector lens, several constant-current sources are fixed on the radiator by dress simultaneously, radiator is a kind of ad hoc radiator that vacuum cavity is arranged, and being provided with many fin around the vacuum cavity is that led chip dispels the heat fast.Its principle is to utilize to add an amount of working solution in the vacuum cavity, the taper gengon LED combined light source that radiator can be set is arranged the heat on the seat, with transferring to apace in the time on the many fin that are provided with around the whole vacuum cavity, the heat that is produced during the work of the heat sink upward led chip of pedestal looses apace and derives, keep low temperature when making led chip work, solve above many disadvantages.
The irradiation light of single power 2800W of above-mentioned a kind of led light source, the heat sink pedestal of the combined light source of wherein single group power 140W is the metal plate of a cuboid or square, offer on self pedestal some suitable for reading big, young pit tongue limit body serves as the reflection wall of led chip down, the welding led chip is installed at the end, groove hole, the two in described groove hole, tongue shoot off can mounting circuit boards the size of width, the board circuit plate is beared down on one be installed in the two in heat susceptor deep gouge hole just becoming led chip, negative pole, wiring board bears down on one and is located at the wiring board top, by the key screw metal derby, wiring board, wiring board bears down on one fastening, the groove hole that the wiring board at two and wiring board bear down on one and just sealed two, perfect some reflective groove cups have been formed, in the interior every groove cup of described some reflective groove cups, be installed in the described groove cup that is concaved with several led chips series connection welding, the circuit board welded disc is electrically connected with gold thread with chip electrode.
The irradiation light of single power 2800W of above-mentioned a kind of led light source, the irradiation light of single power 2800W of whole LED light source wherein, light source is made up of the combined light source of 20 groups of single group 140W, be installed in the plane seat that taper gengon LED combined light source is arranged on the seat, there are 5 direction positions at described seat that the radiator of establishing vacuum cavity sets, the combined light source that can arrange 4 groups of single group 140W on the plane seat of each direction position is by collector lens, and reflector is finished the irradiation light of single power 2800W of a kind of led light source.
The irradiation light of single power 2800W of above-mentioned a kind of led light source, wherein radiator is that ad hoc system a kind of establishes in the radiator of vacuum cavity and add an amount of working solution, be provided with many fin around the cavity, area of dissipation is not less than 128000 square centimeters, and the height of vacuum cavity equates substantially with the radiator height.Add an amount of working solution in the radiator vacuum cavity, the principle that can shift the conduction heat fast is: a large amount of heat that produces when led light source is worked on set position, when this end points is heated, this heat can be near the working solution fluid vaporization the body wall, start working about 30 degree, this moment, the vapour pressure of heating end can raise, make steam move and produce steam flow toward the lower condensation end of air pressure, steam borrows capillary force to be back to evaporation ends and to have finished a circulation coagulating end cooling release heat and condensing into liquid.Add an amount of working solution by vacuum cavity and conduct heat, still do not alleviate the weight of light fixture self, the more important thing is and to transfer to the big calorimetric that an end points produces fast on cavity many fin all around, its conduction of velocity is 100 times of fine copper, 200 times of fine aluminium will solve the heat radiation difficult problem of the irradiation light of single power 2800W of a kind of led light source with this technology.
After adopting technique scheme, the heat that has solved the irradiation light of single power 2800W of a kind of led light source is concentrated.Difficult problems such as heat radiation difficulty, fluorescent material are easily aging, when making the irradiation light work of single power 2800W of a kind of led light source, led chip for good and all keeps low-temperature condition, and life-time dilatation plays conclusive effect to led chip.Brought into play single LEDs chip array module planar light extracting, advantage such as single light flux is big, and lamp distribution is easy.
