[function of capacity cell and configuration detailed]
Then, the function and configuration of the capacity cell 16 in light-emitting device 10 are illustrated.First, to capacity cell 16 function illustrates.As previously discussed, capacity cell 16 is smooth as being carried out to the pulsating volage for being supplied to LED element 14 The smoothing capacity device of change plays a role.Fig. 4 is for illustrating that capacity cell 16 carries out the smoothing figure of pulsating volage.
Fig. 4 shows the waveform for the voltage for being supplied to multiple LED elements 14.As previously discussed, power circuit is to LED element 14 luminous is controlled, so that more LED elements 14 is just made to shine during the voltage of pulsating volage is higher.Therefore, During voltage is low, the brightness of light that light-emitting device 10 is sent out can be made to reduce (alternatively, light-emitting device 10 is all turned off the light). The reduction of this brightness can generate flickering to user.
Therefore, capacity cell 16 is electrically connected in series or in parallel with multiple LED elements 14, as shown in figure 4, in voltage waveform The lowest point during T, by discharging come offset voltage value (voltage value is made to increase).In this way, capacity cell 16 can reduce luminous dress Put the flickering of 10 light sent out.
Here, if capacity cell 16 is large capacity, this capacity cell 16 can more effectively reduce light-emitting device 10 The flickering of the light sent out.Large capacity for example refers to that capacity is more than 10 μ F.In addition, the capacity cell 16 of large capacity due to The size of main part 16a is also big, if therefore as shown in figure 5, orthogonal with the interarea of substrate 11 with the length direction of capacity cell 16 Mode is installed, then can lead to the size increase of the thickness direction (Z-direction) of light-emitting device 10.I.e., it is difficult to make light-emitting device 10 slimmings.Fig. 5 shows the installation example of capacity cell 16.
In addition, in the installation example of Fig. 5, explosion-proof valve 16c is located above.In general, match in explosion-proof valve 16c with opposite Between the component (framework 40 in the installation example of Fig. 5) put, it is contemplated that the opening situation of explosion-proof valve 16c, and need setting one Segment space.In this way, by the top installation space in capacity cell 16, therefore, the height of luminaire 2 can further increase Greatly.
Therefore, it is realized as shown in fig. 6, also allowing for by the small multiple capacity cells 18 of each capacity specific capacitance element 16 The equal function with the capacity cell 16 of large capacity.Fig. 6 shows the installation example of the smaller capacity cell 18 of capacity.
However, the problem of installation example shown in fig. 6 is, the mounting area increase of capacity cell 18 shines Size under the plane of device 10 regards increases.Also, there is also due to mounted capacitance member in installation example shown in Fig. 6 The quantity of part 18 increases, and leads to the problem of the increasing of component installation procedure to substrate 11.
Also, for the service life of component, compared with the smaller capacity cell 18 of capacity, large capacity Capacity cell 16 long lifespan.Therefore, the light-emitting device involved by installation example shown in fig. 6 also there is the service life shorter to ask Topic.
Therefore, as shown in Fig. 2, Fig. 3 A and Fig. 3 B, capacity cell 16 is with the length direction of capacity cell 16 in substrate 11 The rectangular mode upwardly extended, was fallen in substrate 11.In addition, the length direction of capacity cell 16 also can be in other words, greatly Cause the lead 16b of the cylinder axis direction, lead 16b of cylindric main part 16a from the direction that main part 16a is protruded or before bending Extending direction etc..
Hereby it is possible to it is thinned light-emitting device 10 (luminaire 2, lighting device 1).Also, in this configuration, by Upwardly extended in the length direction of capacity cell 16 in the rectangular of substrate 11, thus can reduce substrate 11 width (X-direction Length).That is, the miniaturization of light-emitting device 10 can be also realized in the direction of the width.Also, compared with the example of above-mentioned Fig. 6, Light-emitting device 10 has the advantage that in place of service life and number of components.
Also, capacity cell 16 is formed the opposite side of other circuit elements of power circuit with explosion-proof valve 16c directions Mode, fallen in substrate 11.That is, capacity cell 16 is configured towards no in multiple circuit elements 15 with explosion-proof valve 16c The mode in the direction of any one, be configured in the multiple circuit elements 15 for forming power circuit (length direction is most for most end End).
Accordingly, in the case where explosion-proof valve 16c is opened, multiple circuit elements 15 other than capacity cell 16 can be inhibited to go out Existing failure.
But the lead 16b of capacity cell 16 bendings that light-emitting device 10 has.Therefore, light-emitting device 10 is had Capacity cell 16 compared with installation example shown in fig. 5, lead 16b long.In this way, heat is not easy to be transmitted to master via lead 16b Body portion 16a.Therefore, will not easily cause to deteriorate (can realize long lifetime) due to the heat that capacity cell 16 generates.
In addition, the region of the lower section of capacity cell 16 in substrate 11 can than other regions wiring pattern (per single The ratio of the wiring pattern of plane product) it is few.Accordingly, heat is not easy to be transmitted to main part 16a from substrate 11.It in this way, will not be easy Ground causes to deteriorate (can realize long lifetime) due to the heat that capacity cell 16 generates.
Also, in Fig. 3 A and Fig. 3 B, although the main part 16a of capacity cell 16 is abutted with the upper surface of substrate 11, It but, can also there are gaps between the upper surface of main part 16a and substrate 11.In the upper table of main part 16a and substrate 11 Between face, retainer of position of the heat sink materials such as fixed heat dissipation silicon or capacity cell 16 etc. can also be configured to.
