Description
Technical field
The present invention relates to a kind of LED illumination assembly, a kind of integrated many kinds of measures is to reduce caloric value, the ease wind formula LED illumination assembly avoided hot stack in lamp body, all kinds of lamp outer casing can be coordinated to use.
Background technology
At present, all kinds of high-power LED lamps use natural heat-conducting, heat radiation and convection type heat radiation mostly, to ensure that lamp bead operating temperature is less than rated temperature (operating temperature < 75 °), but owing to the requirement irradiated area of outdoor lamp is big, LED power increases the most therewith, general LED lamp power is more than 60W, and even up to 200W, heat radiation contradiction is the most prominent.
At present, most of LED lamp take aluminium radiator, non-intervention formula conduction of heat, heat radiation and heat loss through convection, and no matter how radiator structure changes, and the counterweight of aluminum mass shell body is answered > 100g/W, torrid areas even uses higher standard.The heat exchange amount of thermal convection current mode and area of dissipation and hot temperature difference are directly proportional；The difference of 4 powers of heat loss through radiation and light fixture radiating surface temperature and 4 powers of ambient temperature is directly proportional, so when outside air temperature is higher, conventional lamp radiating mode formula function fall of suddenling change is weak.
It addition, for the thermal capacitance ensureing light fixture, it is necessary to expend substantial amounts of aluminium, the cost of light fixture has virtually been significantly greatly increased, and has strengthened the consuming of natural resources.Further, since the increase of lamp holder weight, body of rod design consequently also needs to become 3 power ratios to increase on steel using amount, thus the derivative cost made new advances and the wasting of resources.Simultaneously, our country's light trade for many years develops, develop substantial amounts of sodium vapor lamp and halogen lamp mould, but all use because heat dissipation problem two is not suitable for LED lamp, need to eliminate, and LED lamp substitute conventional light source trend settled finally, therefore the most therefore and cause mould waste will reach tens billion of meter.
Summary of the invention
The technical problem to be solved is to overcome prior art defect, it is provided that a kind of high efficiency and heat radiation that can realize high-power LED lamp, and greatly reduces use aluminum amount, and the LED illumination assembly of heat radiation cost is greatly lowered.
In order to solve above-mentioned technical problem, a kind of LED illumination assembly that the present invention provides, including LED lamp bead；Described LED illumination assembly also includes fixing the lamp panel heat-dissipating aluminium plate of LED lamp bead, middle level wind guide and heat dispersion aluminium sheet, upper strata wind guide and heat dispersion aluminium sheet, fan, support；Described upper strata wind guide and heat dispersion aluminium sheet is provided with wind guide tank, and described middle level wind guide and heat dispersion aluminium sheet is provided with the heat dissipation channel corresponding with wind guide tank, and described lamp panel heat-dissipating aluminium plate is provided with the ease air port corresponding with heat dissipation channel；Described lamp driving power source includes LED constant current source, fan power supply；Described lamp driving power source, fan are each attached on support, and support is being provided with opening with fan corresponding section.
As improvement, described fan is magnetic suspension bearing radiator fan.
As improvement, between described middle level wind guide and heat dispersion aluminium sheet and upper strata wind guide and heat dispersion aluminium sheet, it is provided with temp control switch and temperature protection switch.
As improvement, described temp control switch and temperature protection switch are dry-reed.
As improvement, described fan is non-contacting with upper strata wind guide and heat dispersion aluminium sheet.
As improvement, the wind guide tank of described upper strata wind guide and heat dispersion aluminium sheet is wedge shape.
As improvement, described middle level wind guide and heat dispersion aluminium sheet heat dissipation channel is bar shaped.
As improvement, described lamp panel heat-dissipating aluminium plate is additionally provided with air inlet.
As improvement, described LED lamp bead uses 20 string N mode also
The beneficial effects of the present invention is: upper strata wind guide and heat dispersion aluminium sheet, middle level wind guide and heat dispersion aluminium sheet and the lamp panel heat-dissipating aluminium plate of (1), the present invention forms three layers of radiator structure by pressing, a part for fan air-out can be strengthened blast and import the bar shaped heat dissipation channel of middle level wind guide and heat dispersion aluminium sheet by the wedge shape wind guide tank of upper strata radiating aluminium sheet, then escape external, thus greatly reducing the hot stack of lamp interior, it is ensured that temperature and the temperature difference of surrounding enviroment within lamp body are less than 10 °；Meanwhile, another part is introduced into the air-flow in air channel to carry out heat exchange by the upper surface of upper strata wind guide and heat dispersion aluminium sheet and carries out partial circulating in lamp body, excretes the most successively when reaching higher temperature, and this is also avoided the dust brought because air is imported and exported on a big scale to pollute；(2), the magnetic suspension bearing radiator fan of the present invention, fan volume is little, power is low, it is possible to achieve according to the proportional arrangement fan of LED power/radiator fan power=50:1, and sufficiently achieve radiating effect；(3), fan and the upper strata wind guide and heat dispersion aluminium sheet of the present invention is contactless, compressed air stream at fan outlet most through radiator interior surface formed internal heat exchange convection current, another fraction escapes external after flowing through radiator inner passage, so the windage of gas channel is substantially reduced, the flow-disturbing effect of radiator fan is greatly enhanced；(4), the air inlet of the lamp panel heat-dissipating aluminium plate of the present invention ensure that lamp interior can enter cool ambient air in real time, thus in ensureing lamp body, inner air pressure does not reduces because of outer heat extraction air, thus lamp body temperature also will not persistently raise；(5), the effect of the tongue tube temp control switch of the present invention is that, when natural heat dissipation mode can not meet radiating requirements, after lamp bead temperature reaches design temperature, control switch is opened, and radiator fan is started working；The effect of temperature protection switch is, when lamp bead temperature rises to protect switch to damage at fan, the temperature of heat-dissipating aluminium plate can steeply rise, and at this moment temperature protection switch plays a role, and closes lamp bead electric current, thus protects lamp bead will not burn because temperature is too high；(6) LED lamp bead of the present invention use 20 string N and mode, thus improving often group lamp bead voltage is original 2 times, on the premise of power is constant, 20 string N and lamp bead electric current compared with 10 string 2N and lamp bead electric current decrease half, so the gross calorific power Q=I of lamp bead2RT reduces to the 1/4 of original caloric value.
