DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the device according to the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing an assembled state of an embodiment of a lighting element with a cover according to the present invention, and FIG. 2 is a front view thereof, partially cut away to facilitate understanding of an internal structure. FIGS. 3, 4, and 5 are a plan view, an AA sectional view, and a front view of the socket used in the embodiment, respectively. FIG. 6 is a plan view of the substrate of the embodiment.

Referring to FIGS. 3, 4 and 5, the socket will be described first. The socket is a resin molded product, and the base 6 of the socket is for receiving and supporting the electrodes of the wedge-based light emitting element 1. In this embodiment, an incandescent lamp using a tungsten filament is used as the light emitting element 1. A space for receiving and supporting the contact 16 and the wiring connection 18 (see FIG. 1) is provided inside the base 6.

The flange 5 is provided with two divided grooves 4 connected to the base 6 and communicating with the inside. An engagement protrusion 11 is provided on the flange portion 5, and the protrusion 11 is engaged with an engagement groove 22 of the substrate 20, which will be described later, to position the socket with respect to the substrate 20. The four engagement claws 7, 8, 9 and 10 are elastically bent inward and can be restored.

A plurality of engaging claws 7, 8, 9 and 10 divided into four are provided above the flange 5. These claws are arranged so as to be spaced from and surround the outer wall of the light emitting element 1. Grooves are provided on the outer periphery of the claws on the upper surface of the flange 5 of the engaging claws 7, 8, 9, and 10, respectively. The engaging claws 9 and 10 are provided with grooves 9a and 10a. This groove width corresponds to the thickness of the mounting substrate 20 (see FIG. 6) described later. The engaging claws 7 and 8 are provided with grooves 7a and 8a. This groove width corresponds to the sum of the thickness of the mounting substrate 20 described later and the thickness of the thick portion 3 at the lower end of the cover 2.

As shown in FIG. 6, the substrate 20 is provided with a hole 21 for mounting the socket and an engaging groove 22 for engaging with the projection 11 provided on the flange 5 of the socket. It is assumed that the board 20 supports a large number of sockets, but in this embodiment, one of the 16 sockets is shown.

Next, the assembly of the light emitting element will be described.
As shown in FIG. 1, a contact metal plate 1 is provided inside the base of the socket.
The wiring connection portion 18 to which the wiring 6 and the wirings 14 and 15 are connected is mounted and fixed, and the wedge-based incandescent lamp 1 is inserted and fixed. In this state, when inserted into the hole 21 from the back side of the substrate 20, the engaging claws 7, 8, 9 and 10 are bent and inserted inward, and the flange 5 comes into contact with the back surface of the substrate 20, When the projection 11 is made to correspond to the engagement groove 22, the grooves 9a, 10a
Then, the substrate 20 snaps into place. In this state, when the cover 2 is put on the front side of the substrate 20, the thick portion 3 of the cover 2 fits into the outer peripheral groove 8a together with the substrate.

The heat generated by the incandescent lamp 1, which is a light emitting element,
When the temperature of the air around the bulb rises, arrows P and P in FIG.
The air circulation paths indicated by Q and R are formed, and the internal air circulates. Therefore, the temperature of the air in the cover 2 is maintained at a temperature that is not much different from the temperature of the external atmosphere.

Next, a second embodiment of the apparatus according to the present invention will be described with reference to FIGS. FIG. 7 is a view showing an example in which a cover is directly attached to a low-heat-emitting bulb according to an embodiment of the second covered lighting element according to the present invention, and FIG. 8 is an embodiment of the second covered lighting element according to the present invention. It is a side view which shows an assembly state. In the second embodiment, a light-emitting element that generates low heat is used, and a cover is directly placed on the light-emitting element.

As shown in FIG. 7, the low heat generating bulb 31 is directly inserted into the cover 32 and fixed. The cover 32 is made of silicone rubber and contains any of red, green and blue pigments. Low heat generation means that the cover 32
This is a heat generation that does not cause deterioration, discoloration or fading. In the figure, the portion indicated by the numeral 31a is an electrode of the wedge-based low heat generation bulb 31.

As the socket 6, the one described above with reference to FIGS. 3 to 5 can be used as it is. But,
As described above, there is no need to support the cover with the engagement claws 7, 8, 9 and 10. Therefore, the grooves provided on the outer periphery of the upper surface of the flange portion of the engaging claw are grooves 10a, 38a and the like corresponding only to the thickness of the substrate 20. The other parts are not different from the above-mentioned shapes, and thus the description is omitted. The socket 6 is inserted into the socket 20 from below the substrate 20 (FIG. 8), and is coupled to the substrate 20 through the groove.

The embodiments described in detail above can be variously modified within the scope of the present invention. Although an example of a light bulb using a tungsten filament as a light emitting element has been described, an LED or a discharge lamp may be used. It does not prevent accommodating a plurality of light emitting elements.

[0017]

As explained in detail above, in the first embodiment of the light emitting element socket according to the present invention, a base for receiving the electrode of the light emitting element, and one or more divided parts connected to the base and connected to the inside. A flange portion having a groove, a plurality of engaging claws divided into a plurality of portions above the flange portion and arranged so as to be spaced from and surround the outer wall of the light emitting element, and the flange portion of the engaging claw portion A groove corresponding to the thickness of the substrate provided on the outer periphery of the upper surface and a groove corresponding to the thick part of the cover; Therefore, even if the cover is attached, a communication path with the outside air can be secured, so that the temperature rise of the air in the cover can be suppressed.

In the first embodiment, the engaging claw portion is inserted from the lower side of the board 20 (FIG. 2) in a state where the light emitting element is inserted into the socket or not inserted into the socket, and the board is inserted in the groove. The cover is covered on the outer periphery of the engaging claw portion, and the thick portion of the cover is connected to the engaging claw portion. Therefore, assembly is very simple. Also in the second embodiment, as in the first embodiment, assembly is extremely simple. In the second embodiment, an appropriate gap is formed between the light emitting element and the socket, and the light emitting element generates low heat. Therefore, the cover does not discolor.
