The present invention relates to an LED bulb used in combination with a socket, and more specifically, a reflector is inserted inside the light bulb of the LED bulb, and the reflector is an inner magnet placed inside the reflector and an outer surface located on the outer surface of the floodlight The present invention relates to an LED light bulb that is attached by mutual attraction between the magnets and allows the user to adjust the desired direction, so that the lighting light of the LED light bulb can be reflected or blocked in various directions.

A socket type light bulb that is generally widely used refers to a lighting device that obtains light by injecting a non-combustible gas into a glass ball in a vacuum state and electrothermally emitting ancestors such as tungsten. Light bulbs are widely used in flash, various lamps in automobiles, and general lighting equipment.

However, such a socket-type light bulb has a structure in which a filament is installed in a glass sphere of a vacuum to supply electricity and emit light, so there is a problem of large power consumption and low illuminance, and the life of the filament itself is short, so that it is long There is a limitation in durability that cannot be used for a while, and if the filament in the bulb is broken and cannot emit light, the entire bulb must be discarded, thereby increasing maintenance and management costs.

Therefore, in the case of the socket-type light bulb as described above, by using a light emitting diode (LED: light emitting diode) as an internal light source, a power saving effect can be obtained by taking advantage of low voltage and small power, and the existing filament type light bulb Compared to this, it has been improved to obtain a significantly increased durability and service life.

Particularly, as disclosed in Patent Publication No. 2001-0029575, a socket coupling portion is provided on the outer upper portion, and a cap engaging groove is formed on the outer periphery of the opening, and the body portion is detachably installed in the light bulb socket while fixing each component. Wow; A plurality of light emitting diodes which are installed toward the reflecting means inside the body portion or on the opening to generate light of a predetermined color when power is supplied; A reflecting means formed in the body portion and reflecting light emitted from each light emitting diode to the front portion through an opening in the body portion; In a conventional light bulb that uses a filament by integrally provided with a hooking hook that is hung in a locking groove of the body portion on an inner circumferential surface and detachably installed on an opening of the body portion to prevent foreign matter from entering the body portion Compared to this, the power saving effect and durability can be greatly improved, and the illuminance can be freely adjusted through adjustment of the power voltage supplied from a control unit installed outside or inside, as well as various colors of lighting can be recycled. A socket-type light-emitting diode light bulb has been devised so that it is easy to greatly improve the merchandise and reliability of the product itself.

Subsequently, as shown in Patent No. 10-1176909, an opening is formed at one end and a base body having a hemispherical shape in which a heat dissipation part is formed at an outer circumference, and is integrally extended from the other end of the base body, and is a socket coupling body to which the socket is coupled. A base made of; An LED substrate fixedly installed on the inner circumference of the base body through the opening, capable of mounting double-sided components, and mounting LEDs; And a hemispherical diffusion cap that is detachably coupled to the opening of the base and diffuses light emitted from the LEDs to the outside. Accordingly, the present invention simplifies the structure of the LED bulb, and the LED bulb is easily installed and registered to prevent the loss of emitted light and to easily attach and detach the diffusion cap. .

In addition, as shown in Patent No. 10-1463353, a socket bolt to which power is connected is provided, a resistor and a Zener diode for controlling voltage are installed inside the socket bolt, and an insulation of a fallopian tube shape is formed around an upper portion of the socket bolt. In the insulator is installed, the LED insulator is installed inside the insulated insulator to be electrically connected to the socket bolt, in the LED light bulb, the LED light-emitting portion, the lower side is fitted on the inner circumferential surface of the socket bolt and the center hole is perforated cylinder An absence of shape; An LED substrate attached to a circular upper surface and an inclined side surface of the cylindrical member; As it is composed of an insulating column inserted in the center hole of the cylindrical member, the LED of the disk-shaped LED substrate illuminates the room vertically downward, and the LED of the strip-shaped LED substrate is lateral upward, that is, the ceiling direction. The LED light bulb has the effect of illuminating the light with the effect of allowing the room to be illuminated more brightly.

However, the existing LED light bulb has a form in which the lighting light of the LED light source located in the circular glass sphere or the transparent sphere is irradiated as it is in the indoor direction, and thus it is impossible to control the irradiation direction or the irradiation angle of the lighting light. will be.

Therefore, in order to adjust or change the irradiation direction or the irradiation angle for the existing LED bulb, the socket device to which the LED bulb is coupled is configured to rotate or additionally configured with a reflector of a separate configuration in the mounting portion of the LED bulb. That is true.

Accordingly, since the expensive lighting device itself is used to adjust the irradiation direction and the irradiation angle for the lighting of the LED bulb, the lighting lamp itself is very expensive, and it is very uneconomical because the ceiling work and fixing work to install it must be accompanied. However, it is necessary to operate the mechanical control device of a complicated device or configuration every time, and the inconvenience in use also has a very large end.

In addition, the adjustment means and device for the irradiation direction and the irradiation angle as described above is made of a very large and complex shape compared to the size of the existing LED bulb, so that the adjustment means and device are exposed from the outside, so it is not suitable for the interior of the room. Of course, it has problems that are not concise in appearance.

At this time, the base 10 is made of an insulator, and the lower socket coupling portion 11 is made of a metal material, and when coupled with a socket, power is supplied to the LED light source body 30 through the socket coupling portion 11. It is to serve as a supply.

In addition, the transparent sphere 20 is made of a transparent or translucent glass or synthetic resin material, and the open lower end of the transparent sphere 20 is fixed to the front end of the base 10 to be a single object. The light bulb is made.

Subsequently, the LED light source body 30 is made by mounting a plurality of light emitting diodes on a circuit board, and when the post 12 made of an insulator protrudes from the upper side of the base 10, the post 12 The LED light source body 30 is secured and fixed to the front end of the LED, and the separately provided translucent cover body 13 is coupled to the front end of the post 12 so that the LED light source body 30 is inside the translucent cover body 13. ) To be accommodated.

At this time, the LED light source body 30 is ideally located at the inner center of the light transmitting sphere 20, and in the case of the translucent cover body 13, the LED light source body 30 is concealed to produce external beauty. At the same time, when the light emitting diode of the LED light source 30 is lit, it serves as a diffusion member that prevents direct glare from the lit light.

In addition, when power is applied to the socket coupling portion 11 like a conventional LED light bulb, it has a structure in which power is applied to the LED light source body 30 through the interior of the post 12, as required. A power supply (SMPS) may be integrated in the interior of the base 10 or post 12.

Subsequently, the reflector 40 inserted into the projection 20 is coupled to the lower end of the projection 20 on the upper side of the base 10, and is fixed through the lower end of the opened projection 20. As it is inserted, preferably, the reflector 40 of the thin synthetic resin in the form of a cowl is bent lightly so that no fold line is generated, and is pushed into the inside of the floodlight 20 through the lower end of the floodlight 20. .

At this time, a circular inner magnet body 50 is positioned at the inner center of the reflector 40, and a guide washer 70 provided separately at the outer center of the reflector 40 corresponding to the inner magnet 50 By inserting the inside of the light-transmitting sphere 20 in a state where they are attached to each other, the inner magnet body 50 generates mutual attraction with the outer magnet body 60 for fixing the reflector 40 to the light-transmitting sphere 20. For the guide washer 70, the ball-shaped inner magnet 50 positioned inside the reflector 40 is attached to the reflector 40 to be inserted into the inside of the light-transmitting sphere 20.
