Description

The present invention relates to a light bulb type lamp using a light emitting element such as an LED (light emitting diode) as a light source.

A light bulb type lamp using an LED as a light source is known as a product that consumes less power than an incandescent light bulb using a filament as a light source. The bulb-type lamp has the same base as the incandescent bulb, and is structured to be attached to the same socket as the incandescent bulb. In addition to the LED that is the light source, this bulb-type lamp requires a drive circuit that drives the LED, a heat radiating part for reducing the temperature rise of the heat generating part inside the lamp, etc. Compared to the above, the number of parts is large and the structure becomes complicated.

In the light bulb-type lamp of Patent Document 1, wiring holes are formed in the element substrate and the heat radiating body. However, since the holes need to be aligned with each other and are aligned visually, the assembly process is increased by positioning confirmation. Is concerned.

The radiator is made of a metal such as aluminum, and a cup-shaped storage case for storing the lighting device is interposed between the caps located below the heat sink, and the heat is dissipated by the flange portion of the storage case. The body and base are electrically insulated. The flange portion of the storage case protrudes in the radial direction and is continuously formed in the circumferential direction in order to insulate the main body cover and the base, and the storage case is inevitably inserted from the lower side of the main body cover. Therefore, since the storage case of patent document 1 is a shape which covers the upper part and side surface of a lighting device, a lighting device can be accommodated only from the lower side of a heat radiator. And, in order to connect the lighting device to the element substrate mounted on the upper surface of the radiator, the element substrate is previously connected with a long lead wire before the lighting device is stored in the storage case from the lower side of the radiator. Then, the lighting device must be stored in the storage case from the lower side of the radiator. Thus, when it is set as the structure which accommodates a lighting device from the lower side of a heat radiator, it is necessary to connect a lighting device and an element board with the lead wire of the length equivalent to a heat radiator in an attachment stage, and as a result It leads to cost increase. In addition, since the storage case has a cylindrical shape, it is difficult to pass the lead wire through the through hole in order to connect the lighting device and the element substrate. Furthermore, since the element substrate is fixed to the heat radiating body with screws, there is a concern that the assembly process is increased and the manufacturing efficiency is deteriorated.

Moreover, in the light bulb type lamp of Patent Document 2, a wiring groove is formed in the heat radiating portion so as to let the wiring from the LED module pass, and the wire is passed through the wiring through hole provided in the center of the heat radiating portion. It is set as the structure connected to the lighting circuit arrange | positioned in the center part. Further, a metal heat dissipating part is provided below the LED module, and an insulating part is interposed between the bases located below the heat dissipating part, thereby electrically insulating the heat dissipating part and the base.

As a result, the interior of the insulating part that insulates the base and the metal heat dissipating part is hollow, and the LED lighting circuit is built in, so the lighting circuit can be inserted only from the lower side of the radiator. I can't. Therefore, similarly to Patent Document 1, it is necessary to connect the lighting circuit and the LED module with a lead wire having a length corresponding to the heat radiating portion, resulting in an increase in cost. Moreover, in the connection work of the lighting circuit and the LED module, there is a concern that the manufacturing efficiency may be deteriorated due to an increase in the assembly process such as a work of passing the wiring through the through hole or a work of turning the wiring groove.

Patent Document 3 and Patent Document 4 are the same as Patent Document 1 and Patent Document 2, and in Patent Document 3, since the drive circuit component of the light source module is built in the cylindrical heat dissipation portion, the drive circuit component is the heat dissipation portion. Can be inserted only from the lower side, and in the mounting stage of the drive circuit component and the light source module, it is necessary to connect with a lead wire having a length corresponding to the heat radiating portion. When accommodated in a cylindrical accommodating part, since it can only be inserted from the lower side of the accommodating part, it is difficult to insert the lead wire into the through hole and the lead wire becomes long. As a result, both patent documents increase the cost. Connected. Further, it is difficult to connect the drive circuit component and the light source module, which leads to an increase in the assembly process, and there is a concern that the manufacturing efficiency is deteriorated.

In addition, since the lead wire 112 of the wiring is taken out from the through-hole portion 92 of the protrusion 91 formed in the lid portion 9 of the storage portion 12a for storing the drive circuit portion 11, a groove portion is provided on the light emitting element substrate 7 to be formed. Thus, the lead wire 112 required for the connection between the light emitting element substrate 7 and the drive circuit unit 11 can be shortened and the wire processing of the lead wire 112 is facilitated, so that the connection work is improved.

In the light bulb type lamp 1 of the present invention, the shape of the storage portion 12b is applicable not only to a shape such as an incandescent light bulb but also to a shape different from a light bulb such as a cylindrical shape or a reflex type, The present invention is not limited to this embodiment, and may be appropriately selected within a range that does not contradict the gist of the present invention.
