Description

[Detailed description of the invention] [Industrial application field] This invention is used for illuminated signboards, indicator lights, etc.
It concerns LED (light emitting diode) lamps.

[Conventional technology] Conventional LED lamps are made by arranging multiple LED light emitting elements on a circular substrate and mounting them on a stem.This stem is welded to a glass bulb, and the exhaust gas is removed as in the production of incandescent light bulbs. It is then sealed with a predetermined inert gas, tipped off, and fitted with a cap. This LED lamp was powered by screwing the base into a socket connected to a power source.

[Problems that the invention attempts to solve] In conventional LED lamps, the LEDs used
There was a problem in that the same number of sockets as the number of lamps were required, and the sockets had to be prepared to match the shape of the base of the LED lamp. In addition, the connection between the LED lamp and the power supply socket is an indirect electrical connection such as screw-in or spring contact, which causes problems such as poor electrical contact and flickering in the lighting. It was hot.

[Means for Solving the Problems] The present invention provides specific means for solving the above-mentioned problems, including a glass bulb filled with an inert gas, a circular substrate on which a plurality of LED elements are arranged,
In an LED lamp consisting of a base, the base is a mounting part consisting of a lamp fitting and a socket part, and an external lead wire for power supply provided along the stem passes through this mounting part. This product provides LED lamps with special characteristics, which can be easily installed on information boards, etc., and can be easily connected to a power supply unit.

[Example] Next, the LED lamp of the present invention will be described in detail based on the illustrated example.

FIG. 1 shows the LED lamp of the present invention, in which a plurality of LED light emitting elements 1 are arranged at arbitrary intervals on a circular substrate 2, and the circular substrate 2 is mounted on a stem 3. This stem 3 is welded to a glass bulb 4 so that the circular substrate 2 is housed inside, and is evacuated and filled with a predetermined inert gas in the same manner as in the manufacturing process of a general incandescent light bulb, and then chipped off. A lamp part is formed, and an external lead wire 3a for power supply provided along the stem 3 is passed through this lamp part to connect the lamp fitting 5.
The external lead wire 3a is passed through the lamp fitting 5, and the socket part 6 is screwed onto the lamp fitting 5 to form a mounting part.

To explain the mounting part, first, FIG. 2 shows the lamp fitting 5, which has no current-carrying lead wires, contact parts, etc., and has a bottom surface side so that the external lead wire 3a can freely pass through. It is formed in an open manner. 3 and 4 show the socket part 6 that is screwed onto the lamp fitting 5,
The socket portion 6 consists of a socket outer shell 6a made of an insulating material such as plastic or rubber, and a socket metal fitting 6b disposed within the socket outer shell 6a and screwed into the lamp fitting 5.

As is clear from the figure, a lead wire hole 6c is provided in the socket outer shell 6a so that the external lead wire 3a can pass through, and this mounting portion does not serve as an electrical conductor but has the function of supplying electricity to the light emitting element 1. It does not have it at all.

Note that power is obtained by connecting the external lead wires 3a to a connection cord from a power source, and the external lead wires 3a are each insulated to prevent short circuits due to contact with each other or with other parts. It is surrounded by a tube 7 made of material and passes through each of the lamp fitting 5 and the socket part 6.

[Effects of the invention] As explained above, by making the cap part a mounting part consisting of a lamp fitting and a socket part,
After embedding the power supply socket in the information board, the LED
This eliminates the hassle of screwing in the lamps, and simply makes a hole in the information board and inserts the LED lamp into it, making it easy to install. This also has the effect that poor contact at the connection point with the power supply unit, which occurs in the case of electric power, etc., is avoided, and electrolysis and flickering of lighting do not occur.

In addition, the strength of the lamp is the same as that of a general lamp, such as the lamp fittings being baked, so there is no difference.
