Secondly, please also refer to Fig. 1 to Fig. 5, about gas chamber clapboard 184, in the first embodiment, gas chamber clapboard 184 comprises a plate body 1842 and protrudes from the one or more spaced dividing plate 1844 in the one side of plate body 1842.Wherein, the size of plate body 1842 is mated with base 1828 and the second lamp body parts 124 of flow field device 182, and plate body 1842 is covered on the first end 1241 of the second lamp body parts 124.In the time that plate body 1842 is covered on the first end 1241 of the second lamp body parts 124, only expose the part of snap-in structure 1821 of base 1828 using the use as connection; Secondly, the dividing plate 1844 of gas chamber clapboard 184 by backstop on base 1828 and with snap-in structure 1821 side by side.Secondly,, except spaced dividing plate 1844, on plate body 1842, more comprise that some location structures are installed with the groove 1841 of snap-in structure 1821.Be with, gas chamber clapboard 184 goes out one or more the second air port 1848 in first end 1241 construction of the second lamp body parts 124, and the second air port 1848, the second air chamber 1245, the first air port 1248 threes communicate, and the second air chamber 1245 is only with the second air port 1848 and the first air port 1248 and extraneous phase blowing air.Therefore flow field device 182 operate produced forced air flow can using the first air port 1248 and the second air port 1848 both one of as air intlet, another is air outlet slit.Moreover, the second air port 1848 and the first air port 1248 lay respectively at first end 1241 and second end 1243 of the second lamp body parts 124, between the second air port 1848 and the first air port 1248, keep a distance, therefore can form the passage of the flow field device 182 running forced air flow that produce.Therefore, the first air port 1248, flow field device 182 and the second air port 1848 are arranged at same air chamber, and air chamber between light-emitting diode lamp-plate 10 and gas chamber clapboard 184.Be noted that, though the first air port 1248, flow field device 182 and the second air port 1848 are arranged at same air chamber, but the second air port 1848 is obtained by the second lamp body parts 124 and gas chamber clapboard 184 construction, and therefore the first air port 1248 of the present invention and the second air port 1848 are not formed in identity element (referring to the second lamp body parts 124 in the first embodiment).
About the first lamp body parts 122, its first end 1221 is as the first end 121 of lamp body 12, and the power supply lamp holder 14 that is spirally connected, 1223, its second end connects first end 1221 and the second end 1223 in order to 1228, the body wall that connects the second lamp body parts 124, the first lamp body parts 122.In the first embodiment, the second end 1223 of the first lamp body parts 122 is open, and it comprises one or more recess 1222 and protuberance 1224 alternate configurations, and body wall 1228 frames cross the partial interior space of lamp body 12, are called the first air chamber 1225.Moreover, on the body wall 1228 of the first lamp body parts 122, comprise one or more location structure 1228 ', locking hole 1248 ' on corresponding the second lamp body parts 124 of those location structures 1228 ', can fix the first lamp body parts 122 and the second lamp body parts 124 by lock solid structures such as screws (not painting on figure).
Then, in the time forcing air-cooling assembly 18 to be assembled to the second end 1223 of the first lamp body parts 122, gas chamber clapboard 184 can enter in a part 1225 for inner space for the first lamp body parts 122, and the recess 1222 of the second end 1223 of the first lamp body parts 122 can expose the second air port 1848.Secondly, the plate body 1842 of gas chamber clapboard 184 separates the first air chamber 1225 of the first lamp body parts 122 and the second air chamber 1245 of the second lamp body parts 124.Be noted that the size of the plate body 1842 based on gas chamber clapboard 184 and the size of lamp body 12 coupling, except the snap-in structure 1821 of coupling flow field device 182, plate body 1842 is the design without other transmissions or hollow out.Therefore, the first air chamber 1225 and the second air chamber 1245 atmosphere draught-free each other on macroscopic, and the first air chamber 1225 also can not communicate with the second air port 1848 or the first air port 1248.

According to above-mentioned, the heat producing when light-emitting diode lamp-plate 10 operates, forces air-cooling assembly 18, is discharged to the external world by light-emitting diode lamp-plate 10 by configuration.Also be, force the arrange in pairs or groups setting of air port of air-cooling assembly 18, produce forced air flow, and by forced air flow, the heat of light-emitting diode lamp-plate 10 is taken rapidly out of to the external world of lighting device.Secondly, the forced air flow of forcing air-cooling assembly 18 to produce, its cannot through or the first air chamber 1225 that only a small part provides through the first lamp body parts 122, the heat affecting light-emitting diode lamp-plate 10 that so can avoid the power module in the first air chamber 1225 to produce.Secondly, another advantage of separation the first air chamber 1225 and the second air chamber 1245 is that under the situation losing efficacy at flow field device 182, the heat that power module produces can not affect light-emitting diode lamp-plate 10, can avoid the luminous power of light-emitting diode lamp-plate 10 deteriorated.Understandable, the whether normal signal of the running of flow field device 182 also can be used as the use of the luminous power of controlling light-emitting diode lamp-plate 10, in the time that flow field device 182 cannot normal operation, this cannot normal operation signal can be in order to control light-emitting diode lamp-plate 10, reduce the luminous power of light-emitting diode lamp-plate 10 to extend the life-span of light-emitting diode lamp-plate 10.
Again, according to above-mentioned, the first lamp body parts 122, the second lamp body parts 124 and the gas chamber clapboard 184 of assembly type, provide the easy installation of lighting device of the present invention and dismounting mode, the use of convenient making and follow-up replacing internal part.Secondly, be noted that the second air port 1848 in the first embodiment is to be formed by gas chamber clapboard 184 and 124 construction of the second lamp body parts, but the present invention is not limited to this.Again, the first air port 2248 and the second air port 2848 can not be positioned on the upper or same vertical plane of same level (when the power supply lamp holder of lighting device is on vertical line) (when the power supply lamp holder of lighting device is on horizontal line) substantially.
Figure 13 is the combination schematic perspective view of the second embodiment of the present invention.Lamp body 22 comprises the first lamp body parts 222 and the second lamp body parts 224, wherein the first air port 2248 is arranged on the second lamp body parts 224, and the second 2848 of air ports are arranged at and form on the first lamp body parts 222 and by the body wall perforate of the first lamp body parts 222.; flow field device (not painting on figure) is placed in lamp body 22; and between the first air port 2248 and the second air port 2848, now flow field device can be placed on the first lamp body parts 222 and the second lamp body parts 224 both one of or fall between.Secondly, only comprise on the gas chamber clapboard 284(figure of plate body and be represented by dotted lines its position) flow field device be arranged in the first lamp body parts 222, and between the second air port 2848 and power supply lamp holder 24.Thus, the first air port 2248, flow field device and the second air port 2848 are still arranged in same air chamber, and this air chamber is positioned between gas chamber clapboard 284 and light-emitting diode lamp-plate (and first embodiment same position).
Figure 14 is the combination schematic perspective view of the third embodiment of the present invention.Lamp body 32 comprises the first lamp body parts 322 and the second lamp body parts 324 of assembly type.The first end 3241 that the second lamp body parts 324 are provided with the first air port 3248, the second lamp body parts 324 is open end.3223, second end of the first lamp body parts 322 is blind end (can be used as gas chamber clapboard), and multiple pillars 3844 connect the second end 3223 of the first lamp body parts 322 and the first end 3241 of the second lamp body parts 324.Secondly, flow field device (not showing on figure) can be positioned at the second lamp body parts 324, or between the first lamp body parts 322 and the second lamp body parts 324 but be positioned at same air chamber with the first end 3241 of the first air port 3248 and the second lamp body parts 324.Therefore the second air port 3848 in the 3rd embodiment is to separate the first lamp body parts 322 and 324 construction of the second lamp body parts form by pillar 3844.So still meet the present invention's object.Secondly, the lampshade 36 of the 3rd embodiment has an elliptical light sliding surface, still can reach the effect of leaded light.
Figure 15, Figure 16, Figure 17 are combination schematic perspective views of the present invention fourth, fifth, six embodiment.The lamp body of Figure 15, Figure 16, Figure 17 and power supply lamp holder can be with reference to the first to the 3rd embodiment, the light guide structure of the lampshade 46,56 of fourth, fifth embodiment is the baked donut surfaces just like storehouse, 66, the lampshade of the 6th embodiment is spherical lampshade, object has been all the photoconduction that light-emitting diode lamp-plate is sent and has caused in an extraneous angular range, more than gives an example non-in order to limit the present invention.Secondly, in Figure 15 except the first air port 4248 and the second air port 4844, the lighting device of the 4th embodiment still comprises at least one the 3rd air port 4228 that is arranged on the first lamp body parts 422, is close to power supply lamp holder 44 positions, a for example concealed air vent.In the 4th embodiment, the heat of the circuit board in the first lamp body parts 422, the circuit module on circuit board etc. (not painting on figure) can be disengaged by the 3rd air port 4228, but the 3rd air port 4228 does not communicate respectively with the second air port 4844 with the first air port 4248.
According to above-mentioned, in the time that light emitting diode is applied to high-power lighting device, conduction, free convection and radiation mode that if only rely on, thermal gradient tends to act remove the heat that light emitting diode produces, and certainly will cannot make rapidly lighting device be maintained at a lower temperature and operate.Under this kind of situation, hot environment can be obvious and the luminous efficiency of deteriorated light emitting diode promptly, and reduce the service life of light emitting diode.Therefore, for high-power lighting device, the present invention has adopted the design in the lamp body of forcing air-cooling assembly to be arranged at lighting device, produces a forced air flow the light-emitting diode lamp-plate of flowing through in the lamp body of lighting device, and so taking rapidly lighting device out of operates the heat producing.Although except light emitting diode, the thermal source of lighting device still comprises other elements such as power module or circuit board, in comparison, luminous High Power LED produced heat is shifted out rapidly to lamp body outward should be preferentially processed.Therefore, the forced air flow producing when pressure air-cooling assembly running of the present invention can not be arranged at the element that approaches power supply lamp holder through power module etc., so can more effectively process the heat that lumination of light emitting diode produces.In general design, fin, heat sink etc. that conduction, free convection and the radiation mode of tending to act by thermal gradient adopts, the heat disengage other element runnings such as power module during if be applied to only there is single fin or heat sink in the present invention time; If exist can divide multiple fin of being arranged or heat sink time, also to can be applicable to disengage High Power LED luminous for fin or heat sink.Therefore, luminous High Power LED produced heat is brought to rapidly the lamp body external world by also can arrange in pairs or groups general fin or heat sink of pressure air-cooling assembly of the present invention.
The foregoing is only preferred embodiment of the present invention, not in order to limit claim scope of the present invention, therefore all other do not depart from the equivalence change completing under disclosed spirit or modify, and all should be contained in scope of the present invention.
