The action effect of ligthing paraphernalia 10A is described.
As shown in Figure 1, in the appliance body 20A being installed on ceiling face 11, be provided with the case portion 40 being extruded with top board 42 in the side contrary with ceiling face 11, and there is the cover 30A of the light transmission covering case portion 40.Leaning in the recess 44 of side, ceiling face 11 in case portion 40, accommodates by the power supply unit 48 at the 1st circuit substrate 45 mounting electronic parts 47.
At the top board 42 of the side contrary with power supply unit 48 in case portion 40, the illuminating part 55 by installing LED54 at the 2nd circuit substrate 53 is installed.
1st circuit substrate 45 utilizes connecting line 57 to be connected with the 2nd circuit substrate 53 by being located at the inserting hole 56 of top board 42.
And in the 2nd circuit substrate 53, because the positive back side being provided with the position of LED54 contacts with top board 42, the heat that therefore LED54 sends flows into top board 42 from the 2nd circuit substrate 53, by side plate 41, base plate 22 and to ceiling face, cylinder portion 21 transmits.Thereby, it is possible to the heat sent by LED54 externally dispels the heat from cylinder portion 21, or be delivered to ceiling and dispel the heat, therefore, it is possible to obtain good thermal diffusivity, and can prevent because heat causes the negative effect of the characteristic reduction of LED54 etc.In addition, as described above, be folded with between the 2nd circuit substrate 53 and top board 42 fin material, heat transmission metallic object, resin, good thermal diffusivity can be obtained too.In addition, as the positive back side of position and the structure of top plate contact that are provided with light-emitting component, comprise and be thisly folded with fin material, the metallic object of heat transmission, the situation of resin.
In addition, about the 1st circuit substrate 45 being provided with electronic unit 47 in power supply unit 48, more for caloric value is configured facing to the side contrary with top board 42.
Therefore, the more face of the caloric value of the 1st circuit substrate is positioned at the side, mounted face of ceiling etc., and the heat therefore produced from electronic unit 47 is mainly delivered to the mounted face of close attached portion thus heat radiation.In addition, the top board 42 in the face more due to caloric value and case portion 40 separated by a distance, is therefore difficult to the impact being subject to the heat that electronic unit 47 sends, and the heat that LED54 sends is easy to flow into top board 42 from the 2nd circuit substrate 53 and discharge.That is, can make the 1st circuit substrate different from the path of the respective heat spreader of the 2nd circuit substrate, thereby, it is possible to obtain the good thermal diffusivity of thermal release sent by LED54.In addition, also can prevent the heat of electronic unit 47 and the heat of LED54 from mutually having a negative impact via top board 42.
In addition, in the 1st circuit substrate 45, be configured with the 1st installing component group 501 being provided with multiple electronic unit 47 in the 1st face 451 that caloric value is more, be configured with the 2nd installing component group 502 being provided with multiple electronic unit 47 in the 2nd face 452 of the side contrary with the 1st face 451.
And due to the electronic unit 472 of maximum for size H2 is configured at the 2nd installing component group 502, therefore the 1st circuit substrate 45 leaves the top board 42 in case portion 40.
Thus, space between top board 42 and the 1st circuit substrate 45 plays a role as so-called insulated space, therefore without the need to changing the size of recess 44, just can increase this insulated space than ever, therefore, the top board 42 in case portion 40 is difficult to the impact being subject to the heat that electronic unit 47 sends, therefore, it is possible to reduce the situation producing the negative effect that the heat from electronic unit 47 brings in LED54.
In addition, the heat trnasfer that LED54 sends, to top board 42, side plate 41, such as, from releases such as the cylinder portions 21 of ceiling face 11, appliance body, thus can prevent the characteristic of the luminous efficiency of good thermal diffusivity and LED54 etc. from reducing.
In addition, owing to utilizing this insulated space to make the heat of LED54 be difficult to be delivered to electronic unit 47 via top board 42, therefore, it is possible to the heat of minimizing LED54 gives the negative effect of coming to electronic unit 47.
In addition, because the 1st circuit substrate 45 utilizes hold-down screw 46 to be fixed on case portion 40, therefore, it is possible to reliably the 1st circuit substrate 45 is installed on case portion 40.
And the protuberance 67 being located at the inside of the inner cover 60 of bottom tube-like presses the perimembranous 531 of the LED54 in the 2nd circuit substrate 53, thus the 2nd circuit substrate 53 is pressed on top board 42.Thereby, it is possible to the 2nd circuit substrate 53 is installed in the mode reliably connected with top board 42.
Namely, owing to there is the small-sized inner cover 60 covering LED54, therefore the heat of LED54 is easily closed in the space in inner cover 60, therefore LED54 is easily subject to negative effect because of the heat of LED54 self, but because the positive back side utilizing the protuberance 67 of inner cover 60 to make to be provided with the position of LED54 reliably contacts with top board 42, therefore, it is possible to the heat sent by LED54 is delivered to top board 42, obtain better thermal diffusivity, thus can prevent the characteristic of LED54 from reducing.
