JP 2004-60072 (5th page)

  However, since the decorative lighting device described in Patent Document 1 does not have a means for positioning each light source unit, the construction work for positioning each light source unit at a predetermined position is troublesome.

  The present invention has been made in view of the above-described reasons, and an object thereof is to provide a decorative lighting device that can easily position each light source unit at a predetermined position.

The invention of claim 1 includes a plurality of light source units each having a light emitting element provided in a case, and a flexible electric wire for connecting the light source units so that the plurality of light source units are arranged in a row, light source units, each having a pull hanging member formed in hook shape that can protrude other member from the outer peripheral surface of the case, the hooking member, and the axis of symmetry straight line connecting the lead portions to each other of the wire on either side surface of the case Thus, a pair is provided at symmetrical positions.

According to this configuration, since each light source unit has a hooking member, it is not necessary to perform a screw tightening operation as in the case of directly attaching to a construction surface using a screw, and only the hooking member is hooked on another member. Thus, each light source unit can be easily attached to a predetermined position. Moreover, the light source unit can be mounted in various ways. For example, the light source unit can be placed at a predetermined position on the construction surface by hooking a hooking member on another member such as a nail disposed at the predetermined position on the construction surface. It is possible to attach the light source unit so that it swings and moves by hooking a hooking member on another member such as a wire installed between two points. Furthermore, depending on which hook member is hooked to another member, the orientation of the light source unit can be selected in consideration of the routing of the electric wire when positioning the light source unit. In addition, if two hook members are provided for each light source unit in this way, there is an advantage that a plurality of light source units can be mechanically connected by connecting the hook members. . Incidentally, the hooking member, for example, you and the like hooking possible hook-shaped hook and a round ring in the other member such as a nail.

The invention of claim 2 is the invention of claim 1 Symbol placement, the light source unit, and having respectively an exit window for emitting the light from the light emitting element on both sides of the case.

  According to this configuration, since light from the light emitting element is emitted from both sides of the case, for example, the light source unit is attached to a predetermined position by hooking the hooking member on another member such as a nail, and the light source from various directions. When the unit is viewed, the range in which the light from the light emitting element can be seen is wider than the configuration in which the light from the light emitting element is emitted from only one surface of the case. In addition, when viewing the light source unit from one direction, for example, when the light source unit is shaken in a state where the light source unit is suspended and attached, compared to a configuration in which light from the light emitting element is emitted from only one surface of the case, The number of times the light of the light source unit appears blinking within a certain time increases, and the light source unit appears to glitter further.

A third aspect of the invention is characterized in that, in the first or second aspect of the invention, the electric wire comprises a curled cord.

According to this configuration, since the electric wire has elasticity, the interval between the adjacent light source units can be freely changed within a range between the state where the electric wire is contracted and the state where the electric wire is fully extended. On the other hand, if a straight cord is used as the electric wire, the wire hangs when the interval between the adjacent light source units is reduced. Therefore, if the interval between the adjacent light source units is narrow, the portion where the electric wire hangs down. It is necessary to hold the electric wire so as not to overlap the light source unit and block light from the light source unit. In other words, the configuration of claim 3 has an advantage that even if the interval between the adjacent light source units is narrow, the holding of the electric wires is unnecessary and the construction is facilitated.

  Since each light source unit has at least one hook member, the present invention has an advantage that each light source unit can be easily positioned at a predetermined position only by hooking the hook member onto another member. is there.

An exit window 5 for taking out light from the light emitting diode 2 is formed on the upper surface of FIG. The light emitting diode 2 has a light emitting diode chip 6 in the center of the exit window 5. A transparent plate 7 having translucency is disposed in the exit window 5, and the circuit board 3 itself is sealed in the case 4 so that the light source unit A ₁ has a waterproof property that can withstand outdoor use. . Further, the case 4 is made of an elastic material, and thus has impact resistance.

Two electric wires 1 corresponding to each of the anode side and the cathode side of the light emitting diode 2 are connected to the circuit board 3, and these electric wires 1 are arranged in one direction in the case 4 (left and right direction in FIG. 2A). ) Are pulled out from both sides. Protrusions 8 that cover the base end of the electric wire 1 protrude from the sides of the case 4 around the portion from which the electric wire 1 is drawn. Projection 8 is made of an elastic material similarly to the case 4, further on the outer peripheral surface of the protrusion 8 is provided a groove 9 formed over the entire circumference in the circumferential direction are two. As a result, the tip of the protrusion 8 can be inclined with respect to the protruding direction of the protrusion 8, and the electric wire 1 can be pulled out from the case 4 at an angle. Here, between the adjacent light source units A _{1 to} A ₄ , each is connected by one electric wire 1, but the electric wires 1 drawn from each may be connected. The plurality of light source units A _{1 to} A ₄ configured in this way are connected in series between output terminals of a power source (not shown).

Incidentally, the light source unit A ₁ has a hook 10 as hooking member protruding from one surface other than the side surface provided with a projection 8 in the outer peripheral surface of the case 4 (the upper end face in FIG. 2 (a)). The hook 10 is formed in an annular shape having a hooking hole 11 in a plane along the front surface of the case 4, and a notch 12 that opens the hooking hole 11 is formed in a part near the base end as a whole. It is formed into a question mark shape in a plane along the front surface of the case 4. Here, the hook 10 is formed integrally with the case 4, but a hook 10 separate from the case 4 may be provided in the case 4.

That is, the hook 10 is formed in a shape that can be hooked to another member, and the other member (hereinafter referred to as a mating member) to be hooked with the hook 10 is, for example, the same shape as the hook 10 or a notch. It is possible to adopt members such as an annular shape without 12 or a wire or nail formed in a rod shape. Here, by causing the mating member to enter the hooking hole 11 of the hook 10 through the notch 12 of the hook 10, the hook 10 is hooked on the mating member. If these mating members are provided at predetermined positions in the decoration object, the individual light source units A _{1 to} A ₄ are respectively positioned at the predetermined positions simply by hooking the hooks 10 on the mating members. Furthermore, the individual light source units A _{1 to} A ₄ can be suspended and attached by hooking a hook 10 on a wire or string erected between two points, and in this case, a plurality of light sources can be attached. The units A _{1 to} A ₄ are arranged along the extending direction of a wire, a string or the like.

In short, in the decorative lighting device of the present embodiment, if there is a portion where the hook 10 is hooked at a predetermined position in the decoration target such as a Christmas tree, the hook 10 in each of the light source units A _{1 to} A ₄ is hooked on the decoration target. Only the individual light source units A _{1 to} A ₄ can be positioned at predetermined positions. Further, even if there is no portion to hook the hook 10 on the decoration object, if the mating member to hook the hook 10 is attached in advance to a predetermined position of the decoration object before the decorative lighting device is installed, this mating member is used. The individual light source units A _{1 to} A ₄ can be respectively positioned at predetermined positions. Moreover, since the hook 10 is only hooked on the mating member, the hook 10 can be detached from the mating member and hooked on the mating member provided at a different position, and as a result, the light source units A _{1 to} A ₄ The position can be easily changed.

In addition, on the construction surface where the decorative lighting device is installed, a plurality of members such as wires and nails formed in the same shape as the hook 10, an annular shape without the notch 12, a bar shape, etc. are arranged vertically and horizontally. Once you have, can be placed in a desired position a plurality of light source units a ₁ to a ₄ 2-dimensionally on the construction surface, a plurality of light source units a ₁ to a ₄ in the form of characters Can be easily arranged along. Thus, since the plurality of light source units A _{1 to} A ₄ can be easily arranged in the shape of characters or the like, it is also desirable to use the decorative lighting device of this embodiment as a light source for advertising billboards and the like. .

Further, in this embodiment, through holes 13 for inserting the fixing screws for fixing the light source unit A ₁ with respect to the decorative object (not shown), each pair of corner portions facing each other in the front surface of the case 4 Is provided. The light source unit A ₁ is not completely fixed with respect to the decoration object by simply hooking the hook 10 on the mating member and can be moved. However, the light source unit A ₁ is screwed using the through holes 13. it is possible to fix the light source unit a ₁ if stopped. Thus, the light source unit A ₁ even if the screwing, when the hook 10 so as to screw the light source unit A ₁ in temporarily fixed state by hooking the mating member, the work of screwing is facilitated .

Incidentally, in FIG. 1 and FIG. 2, the hook member provided on the light source unit A ₁ but only one, as shown in FIG. 3, the hook member 2 is provided with respect to one light source units A ₁ Also good. In FIG. 3, in addition to the hook 10 protruding from one surface of the case 4 (upper end surface in the figure), a round ring 14 protruding from the other surface of the case 4 (lower end surface in the figure) is provided as a hooking member. The circular ring 14 is formed in an annular shape having a hooking hole 15 in a plane along the front surface of the case 4. According to this shape, when the mating member is inserted into the catching hole 15 of the round ring 14, the round ring 14 is caught by the mating member. However, the combination of the hook members provided in _one light source unit A1 is not limited to the hook 10 and the round ring 14, but may be the hook 10 and the hook 10, or the round ring 14 and the round ring 14.

That is, the glittering feeling of decoration objects such as Christmas trees is improved and the appearance is improved.

(Embodiment 3)
As shown in FIG. 5, the decorative lighting device of the present embodiment is different from the decorative lighting device of the first embodiment in that a curled cord is used as the electric wire 1 ′ that connects the light source units A _{1 to} A _4. To do. Other configurations and functions are the same as those of the first embodiment.

That is, in the present embodiment, adjacent light source units A _{1 to} A ₄ are connected to each other by an electric wire 1 ′ made of a curled cord. Since the curl cord is formed in a spiral shape as is well-known, the curl cord has stretchability in the axial direction thereof. According to this configuration, the electric wire 1 ′ is between the contracted state and the fully extended state. the distance between the light source unit a ₁ to a ₄ adjacent in the range can be changed freely.

By the way, if a wire having no elasticity other than the curled cord is adopted as the electric wire, the electric wire is stretched if the distance between the adjacent light source units A _{1 to} A ₄ is equal to the length of the electric wire. When the interval between the adjacent light source units A _{1 to} A ₄ is narrowed from this state, the length of the electric wire is increased by the amount of the narrowed interval, and a part of the electric wire hangs down. Then, the light from the light source unit A ₁ to A ₄ when the hanging portion of the wire overlaps exit window 5 of the light source unit A ₁ to A ₄ is to be blocked by the wires, in order to prevent this, next When the interval between the matching light source units A _{1 to} A ₄ is narrow, it is necessary to hold the portion where the electric wire hangs down. In contrast, according to the configuration of the present embodiment, 'even if narrowing a distance between the light source unit A ₁ to A ₄ adjacent in the state where the fully extended, the wire 1' wire 1 wire 1 'by contracts Therefore, even if the interval between the adjacent light source units A _{1 to} A ₄ is narrow, it is not necessary to hold the portion where the electric wire hangs down as described above. Consequently, with the degree of freedom of arrangement of the individual light source units A ₁ to A ₄ is high, the holding of the wire 1 'is an advantage to say facilitates construction unnecessary.
