Description

  The present invention relates to a light-emitting device holder for fixing a light-emitting device having a light-emitting element on a substrate surface to an attachment target.

2. Description of the Related Art In recent years, a light emitting diode package (hereinafter referred to as a light emitting device as appropriate) having a structure (chip on board) in which a plurality of light emitting elements are mounted on a substrate surface has been used as a high power LED used in an LED lighting device.
Specifically, this light emitting device has a configuration in which a conductor wiring is formed on a substrate such as ceramic, a plurality of light emitting elements are mounted thereon, and the light emitting elements are sealed with a silicone resin or the like.

The method of directly fixing the light emitting device to the attachment target requires a soldering process when attaching the electric wiring, and thus it takes time and effort to fix the light emitting device. Therefore, this method is not a suitable method in terms of fixing workability because the fixing work efficiency of the light emitting device is poor.
On the other hand, in the method of fixing the light emitting device using the holder, the light emitting device is fixed to the attachment target by the holder while the light emitting device is installed in the holder or the light emitting device is installed in the attachment target. However, it is necessary to fix the light emitting device with a holder so as to cover the light emitting device. That is, when fixing the light-emitting device to the attachment target, it is necessary to simultaneously perform two operations, that is, the operation of maintaining the state where the light-emitting device is installed on the holder or the attachment target and the operation of fixing the holder to the attachment target. Therefore, this method is also not a preferable method in terms of fixing workability because it is difficult to fix the light emitting device.
For example, the following techniques have been proposed for the holder for fixing the light emitting device to the attachment target.

  For example, Patent Document 1 describes a holder (connection element) having a contact element that abuts on an electrode of a light emitting device, and enables connection without soldering of a connection cable by the holder. It is stated that you can.

As shown in FIG. 1, the light emitting device 20 has a plate shape as a whole. The light-emitting device 20 includes a plate-like substrate 21, a plurality of light-emitting elements 22 mounted at the center of the surface of the substrate 21, and a pair of foil-like electrodes 23 electrically connected to the light-emitting elements 22. And.
The light emitting device 20 actually includes a sealing resin that covers the plurality of light emitting elements 22, but is not illustrated here. Here, the light emitting element 22 indicates a single light emitting element or an aggregate (light emitting portion) of a plurality of light emitting elements.

≪Mounting target≫
The attachment target T is a target for fixing the light emitting device 20, and is, for example, a housing of an illumination lamp such as a light bulb, a street light, a downlight, or a spotlight, a heat sink, or the like.
As shown in FIG. 1, the attachment target T has a planar portion to which the light emitting device 20 can be attached, and a positioning hole Ta and an attachment target-side fixing hole Tb are provided in the planar portion.
Here, the positioning hole Ta and the attachment target side fixing hole Tb may be through holes. The attachment target side fixing hole Tb is a screw hole into which a screw member F described later can be screwed.

≪Schematic configuration of light emitting device holder≫
The light emitting device holder 10 (hereinafter, appropriately referred to as the holder 10) is a member that fixes the light emitting device 20 to the attachment target T. The holder 10 is a member that can supply electricity from the outside to the light emitting device 20 while fixing the light emitting device 20 to the attachment target T (see FIG. 1).
As shown in FIGS. 1 and 3, the holder 10 includes a holder main body 11 and a claw portion 12 protruding from the bottom surface of the concave portion 16 on the back surface side of the holder main body 11. Furthermore, the holder body 11 protrudes from the periphery of the recess 16 on the back surface side of the holder body 11 and is adjacent to the claw portion 12, and an elastic energization portion provided on the bottom surface of the recess 16 on the back surface side of the holder body 11. 14.
As shown in FIGS. 3 and 8, four claw portions 12 and four positioning portions 13 are provided on the back side of the holder main body 11, and one claw portion 12 is provided with one claw portion 12. The positioning portions 13 are provided adjacent to each other (specifically, the two members are not in direct contact with each other but are close to each other in a pair while providing a slight gap).

<Holder body>
As shown in FIGS. 1 and 3, the holder body 11 has a plate shape, and a through hole 15 penetrating the front surface and the back surface is formed in the center. A recess 16 having substantially the same shape as the light emitting device 20 is formed on the back side of the holder main body 11 so that the light emitting device 20 can be installed (inserted) as shown in FIG.
When the light emitting device 20 is installed in the concave portion 16 (see FIGS. 4 and 7), the light emitting element 22 mounted on the surface of the substrate 21 of the light emitting device 20 faces the through hole 15 of the holder body 11. It is formed to be a position. That is, the recess 16 and the through hole 15 are formed in the holder body 11 so that the light emitting element 22 is positioned in the through hole 15 of the holder body 11 when viewed from the front surface side when the light emitting device 20 is fitted in the recess 16 ( Has been adjusted).
The recess 16 is provided with an elastic current-carrying portion 14 which will be described later on the bottom surface. When the light emitting device 20 is fitted in the recess 16, the back surface of the substrate 21 of the light emitting device 20 protrudes from the back surface of the holder body 11. It is formed to such a depth (see FIG. 4).

And the fixing hole 17 which penetrates the surface and a back surface is formed in the peripheral part so that the holder main body 11 can be fixed to the attachment object T. FIG.
As shown in FIG. 1, the holder main body 11 is a holder main body in a state where the holder 10 is installed on the mounting target T so that the fixing hole 17 and the mounting target side fixing hole Tb provided in the mounting target T face each other. The light emitting device 20 can be fixed to the attachment target T by allowing the screw member F to communicate with the fixing hole 17 and the attachment target side fixing hole Tb from the surface side of the eleventh surface.

  Note that the periphery of the fixing hole 17 (the relief portion 11 b) on the surface of the holder main body 11 is lower than that of the most protruding portion of the surface of the holder main body 11. The holder main body 11 includes the escape portion 11b. When the holder 10 is fixed to the attachment target T by the screw member F, the head Fa of the screw member F can be stored in the escape portion 11b. It can be avoided that the portion Fa protrudes from the surface of the holder body 11 and obstructs the light emission of the light emitting device 20.

Moreover, the opening part 11a of the through-hole 15 in the surface of the holder main body 11 is exhibiting the shape where an internal diameter becomes large as it goes to the surface side. By providing such an opening 11a, the holder body 11 can emit light emitted from the light emitting element 22 from the opening 11a without being blocked.
In FIG. 1, the opening 11 a has a shape in which the inner diameter is linearly increased in a cross-sectional view. However, the opening 11 a may be any shape as long as it does not block the light emitted from the light emitting element 22 as much as possible. Alternatively, it may have a curved shape with a large inner diameter.

The front surface of the holder main body 11 (including the opening 11a) is formed so as to have a higher reflectance than the back surface of the holder main body 11 (formed to have reflection characteristics). That is, the surface of the holder body 11 is subjected to reflection processing (specular reflection processing, diffusion surface reflection processing).
The holder main body 11 is provided in front of the surface (front side) of the holder main body 11 when the light emitting element 22 emits light with the holder 10 holding the light emitting device 20 by exhibiting such a surface. Even if a part of light is reflected by an optical element such as a lens, the reflected light can be reflected further forward (front side) by the surface of the holder body 11.

The reflectivity of the surface of the holder main body 11 (particularly the surface of the opening 11a) is such that specular reflection processing (aluminum deposition, etc.) or diffusion surface reflection processing (white reflective material) 90% or more is preferable.
Specifically, when light is not desired to be diffused (when applied to a condensing lens or the like), it is preferable to perform aluminum vapor deposition on the surface of the holder body 11 in order to reflect light specularly. When it is desired to diffuse the light, it is preferable to coat the surface of the holder body 11 with a white reflecting material in order to diffusely reflect the light.
And as reflection processing (specular reflection processing, diffusive surface reflection processing), there is also a means of polishing the mold (part forming the surface of the holder body 11) used when manufacturing the holder body 11, By this means, the surface of the holder main body 11 is formed so as to have a higher reflectance than the back surface of the holder main body 11, that is, it is formed smoothly.
In addition, although it does not specifically limit about the reflectance of the back surface of the holder main body 11, For example, it is 85% or less.

As shown in FIG. 5, the holder main body 11 includes a pair of energization wirings 19 that electrically connect the pair of elastic energization portions 14 and the outside to each other. The pair of energization wires 19 are drawn out from two lead-out ports 18 provided adjacent to one side surface of the holder body 11.

The light emitting device 20 is further pressed against the elastic force of the elastic energization part 14, so that the surface of the substrate 21 faces the holding surface S of the flange 12 b and the electrode 23 on the surface of the substrate 21 is elastically energized. It will be in the state contact | abutted to the part 14. FIG.
Incidentally, the left and right distance L ₁₂ of the flange portion 12b at this point, since the narrower than the lateral width L ₂₀ of the light emitting device 20, and the substrate 21 backside of the light emitting device 20 on the holding surface S of the flange portion 12b abuts Become. That is, the surface of the substrate 21 of the light emitting device 20 is urged in the reverse direction by the elastic energization unit 14 and the back surface of the substrate 21 abuts on the holding surface S of the flange portion 12b, whereby the light emitting device 20 (substrate 21) is elastically energized. It will be clamped and fixed by the part 14 and the collar part 12b.

Next, the holder 10 is installed on the attachment target T in a state where the light emitting device 20 is held by the holder main body 11 (FIG. 6D). Specifically, the tip of the claw portion 12 and the positioning portion 13 are inserted into the positioning hole Ta of the attachment target T as a pair.
Here, by placing the holder 10 on the attachment target T while pressing the holder 10 in the reverse direction, the back surface of the outer peripheral portion of the holder main body 11 contacts the attachment target T. At this time, the holding surface S of the flange 12b and the back surface of the substrate 21 of the light emitting device 20 are separated by L _S, but the back surface of the substrate 21 of the light emitting device 20 and the attachment target T are in contact with each other. Thereby, the holder 10 can appropriately radiate the heat generated by the light emitting element 22 to emit light from the substrate 21 of the light emitting device 20 to the attachment target T.
In addition, in the state in which the holder 10 is installed on the attachment target T, as shown in FIG. 6D, it is only necessary that the back surface of the substrate 21 of the light emitting device 20 and the attachment target T are in contact with each other. The holding surface S of the collar portion 12b and the back surface of the substrate 21 of the light emitting device 20 may or may not be separated.

Thereafter, the holder 10 is fixed to the fixing hole 17 of the holder main body 11 and the mounting target side fixing hole Tb of the mounting target T by the screw member F from the surface side of the holder main body 11 in a state where the holder 10 is installed on the mounting target T. .
With the above method, the light emitting device 20 can be fixed to the attachment target T using the holder 10.
In addition, when the light emitting device 20 of the light emitting device 20 emits light with the light emitting device 20 fixed to the attachment target T, the holder 10 forms an inclined surface up to the surface of the holder main body 11. Can be discharged from the opening portion 11a of the through hole 15 without blocking.

As shown in FIG. 9, the shape of the surface of the holder body 110 in plan view is not limited to a rectangular (substantially rectangular) shape, and the fixing hole 17 may be formed so as to protrude outward from the periphery of the rectangle. Good.
The shape of the through hole 15 formed in the center of the holder body 11 is not particularly limited as long as the light emitted from the light emitting element 22 can pass through the through hole 15 without being blocked. Therefore, the through hole 15 may be formed to be the same as or larger than the surface shape of the light emitting element 22 in plan view.

  As shown in FIG. 10, the elastic energization part 140 is not limited to a plate-like spring, and may be a coil-like spring. In addition, the elastic energization part 14 (140) is in contact with the electrode 23 of the light emitting device 20 and energizes, and if the light emitting device 20 is urged away from the back surface of the holder body 11, the structure itself is particularly good. It is not limited.

  As shown in FIG. 11, in a cross-sectional view on the surface of the attachment target T when the holder 10 is fixed to the attachment target T, the shape of the claw portion 120 is not limited to a semicircular shape, and may be a rectangle. In addition, since the nail | claw part 12 (120) should just be inserted in the positioning hole Ta of the attachment object T as a pair with the positioning part 13, it may be another shape.

The number of the claw portions 12 is not particularly limited as long as the number of the light emitting devices 20 can be held, and may be two or more. The installation location of the claw portion 12 is not particularly limited as long as it is a location on the back side of the holder body 11 and can hold the light emitting device 20. For example, the light emitting device having four side surfaces as shown in FIG. When 20 is installed in the recess 16 of the holder body 11, the four claw portions 12 may be installed along the four side surfaces.
The same applies to the positioning unit 13, and the number of installations and installation locations are not particularly limited.

As shown in FIG. 6 (b), the left and right distance L ₁₂ of the flange portion 12b is changed, this change is not intended that caused by columnar body portion 12a of the claw portion 12 is elastically deformed, the columnar body portion 12a It may be caused by elastic deformation of the holder body 11 at the proximal end, or may be caused by elastic deformation of both members (the column body portion 12a and the holder main body 11).

  When the light emitting device 20 is installed in the recess 16 of the holder body 11, the back surface of the substrate 21 of the light emitting device 20 and the back surface of the holder body 11 (the most protruding portion of the back surface) are formed to be flush with each other. May be.

  As a modification, the nail | claw part 12 may not be provided with the collar part 12b, but may be comprised only by the column body part 12a. In this case, the light-emitting device 20 is held by holding the opposing side surfaces of the substrate 21 of the light-emitting device 20 with the column portion 12a.

  As another modification, the substrate 21 of the light emitting device 20 may have a configuration in which a concave portion is provided on the side surface so that the claw portion 12 (the flange portion 12b) is buried. In this case, the light emitting device 20 is held by the concave portion and the surface of the substrate 21, and the contact area between the back surface of the substrate 21 and the attachment target T can be increased. As a result, the heat dissipation of the light emitting device 20 is achieved. Can be improved.
