[main unit]
Then, the structure to the LED illumination utensil 1000 as present embodiment for the Fig. 4 is used
The main unit 200 of key element illustrates.The main unit 200 of main unit 200 and Fig. 1
Identical.
Main unit 200 for example includes main board 210 and a pair leaf-spring-like locking piece 220.
Main board 210 for example has along the recess 200 of long side direction Y extension with along long side direction
The inclined plane linking with recess 200 that Y extends.The section shape of the width of recess 200
For concavity, the section shape of the width of described inclined plane is the cone-shaped expanding upward.
Leaf-spring-like locking piece 220 is respectively arranged in the front of the long side direction Y of main board 210
End side and the end side at rear.Leaf-spring-like locking piece 220 is for example formed as towards front end
The shape turned back in the centre in portion 222, have described in turn back end 221.End 221 of turning back has
Curve shape.And, as it is shown in figure 1, can be by making to turn back end 221 through installation portion
The locking hole 26 of the base portion 23 of part 20 and make leading section 222 pass through the card of each side of sidewall portion 22
Determine hole 25, thus by leaf-spring-like locking piece 220 engaging in installing component 20, by main unit 200
It is installed on installing component 20.
Main board 210 and leaf-spring-like locking piece 220 are for example added by implementing bending to metallic plate
Work simultaneously eliminates unwanted part and is formed.
With regard to main unit 200, the such as bottom surface 213 at the recess 211 of main board 210 sets
Put hole (not shown), make the hanger bolt being arranged at ceiling components pass through described hole, and will
The fixing component such as nut is screwed into described hanger bolt and main unit 200 is fixed on described smallpox
Plate parts.
In main unit 200, as structural element, can also possess terminal substrate.Described
Terminal substrate example is such as disposed in the bottom surface 213 of the recess 211 of main board 210.In order to supply electric power
Give to power supply unit 40, it is also possible to be, be connected with at ceiling components side dew at described terminal substrate
The power line going out, is also associated with the electric wire being electrically connected between power supply unit 40.
Hereinafter, pacify to by the LED light source unit 100 shown in Fig. 2 (a) and Fig. 2 (b)
The method being loaded on the main unit 200 shown in Fig. 4 and the LED illumination utensil 1000 of Fig. 1 being set
Illustrate.As described above, make to be arranged at end and the rear in the front of main unit 200
The end 221 of turning back of each leaf-spring-like locking piece 220 of end pass through the pedestal of installing component 20
The locking hole 26 in portion 23, makes leading section 222 pass through each sidewall 22 locking of installing component 20
Hole 25.Thus, shape in the opening portion 211 being accommodated in main unit 200 for the installing component 20
It is installed on main unit 200 under state.Now, the short side direction of the recess 211 of main unit 200
Pair of openings edge part L on X and the one of the cap assembly 30 relative with pair of openings edge part L
To elongated area 33 respectively in the vertical direction vertical with the fitting surface 12 of LED assembling substrate 10
Z is upper overlapping along long side direction Y.And, pair of openings edge part L and cover portion corresponding thereto
A pair elongated area 33 of part 30 directly or indirectly contacts.In such manner, it is possible to by LED
Light source cell 100 is installed to main unit 200 and arranges the LED illumination utensil shown in Fig. 1
1000。
Additionally, in the present embodiment, it is also possible to it is for example manually to bend leaf-spring-like
Locking piece 220 suitably adjusts so that the one of the recess 211 of main unit 200 is split
A pair elongated area 33 of mouthful edge part L and cap assembly corresponding thereto 30 directly or
Ground connection contact.
Hereinafter, it is installed on sky to by the main unit 200 of the LED illumination utensil 1000 of Fig. 1
One example of the method for card parts illustrates.Make to be arranged at the hanging spiral shell of ceiling components
Bolt is disposed through the hole of the bottom surface 213 of the recess 211 of the main board 210 of main unit 200
(not shown), and the fixing components such as nut are screwed into described hanger bolt and are fixed on described sky
Card parts.In such manner, it is possible to the LED illumination utensil 1000 of Fig. 1 is installed on ceiling components.
In the LED illumination utensil 1000 shown in Fig. 1, as described above, pair of openings edge
Base is being assembled with LED respectively in a pair elongated area 33 of portion L and cap assembly corresponding thereto 30
In vertical vertical direction Z of the fitting surface 12 of plate 10 overlapping along long side direction Y.Further, one
To a pair elongated area 33 of opening edge portion L and cap assembly corresponding thereto 30 directly or
Person contacts indirectly.Thus, the LED illumination utensil 1000 shown in Fig. 1 will not be in when lighting
Striated ground is dimmed so that aesthetics during lighting is preferable.
In common LED illumination utensil, use resin as the formation material of cap assembly, make
With metal as the formation material of described appliance body.That is, described cap assembly and described utensil
Main body is formed by the different material of expansion rate.Therefore, the LED illumination recorded such as patent document 1
Utensil is such, described each extension on described orthogonal direction with described opening ora terminalis gapless
In the case that ground is overlapping, due to temperature change during lighting or when turning off the light, can be at described utensil
The contact surface of main body and described cap assembly produces the sound being caused by friction.
On the other hand, in the LED illumination utensil 1000 shown in Fig. 1, at cap assembly 30
The described relative part of a pair elongated area 33 there is friction minimizing portion 35.And,
In LED illumination utensil 1000, by rubbing, minimizing portion 35 reduces a pair at cap assembly 30
The friction producing between the pair of openings edge part L of elongated area 33 and main unit 200.By
This, the LED illumination utensil 1000 shown in Fig. 1 can suppress due to during lighting or turn off the light when
Temperature is sent out when changing and produce the friction of the ora terminalis of the opening of cap assembly 30 and main unit 200
