Description

Light direction changeable conventional light bulb compatible LED lamp}

The present invention is to adjust the direction of illumination, such as downward and sideways of the high-brightness LED bulb that can be inserted into the existing incandescent lamp socket, and to be free to select the heat dissipation problem and the screw stop position of the socket.

Conventional incandescent light bulbs emit light from the filament spreading in all directions, such as up, down, left, and right, so that a reflector is installed on the opposite side to illuminate the light together with the reflected light, but the light emitting diode bulb is a semiconductor chip and an ITO electrode It was forced to produce by fixing the direction of back lighting downward or sideways.

The present invention is to implement a light emitting diode illumination direction in a certain angle range direction, such as from downward to side direction, and to be competitive by selectively using a variety of advantages, such as low power long life wavelength selection than conventional fluorescent lamps built-in ballasts. .

Since Edison invented the filament bulb, the world incandescent bulbs and bulb sockets have been well standardized for over 100 years, and de facto and international standards have been established.

Following the long history of incandescent lamps, fluorescent lamps with built-in ballasts, which are compatible with incandescent lamp sockets, have been commercialized. Rather larger.

Recently, due to mass production of high-brightness LEDs (LEDs), light-emitting diode bulbs have been commercialized in various ways, resulting in perceptual fluctuations in the lighting market, but they are compatible with existing fluorescent and incandescent bulbs. Due to some different characteristics from the existing lighting such as overheating, there are great obstacles in the production and supply of the product, and countermeasures are required.

In order to use the light emitting diode bulb with a conventional incandescent lamp and a ballast integrated fluorescent lamp, it is preferable to adjust the illumination direction of the light emitting diode from top to bottom.

However, the problem of heat dissipation of light emitting diodes and the nut structure of conventional socket sockets must be solved simultaneously. That is, there is no problem even if the incandescent light bulb is radiated in all directions by 360 degrees and the bolt structure of the incandescent light bulb is fixed at an arbitrary position. However, it is free to select the lighting direction of the light emitting diode and the position where the light bulb is rotated and fixed to the socket. need.

While satisfying these conditions, there is a need for a heat dissipation structure capable of dissipating heat generated when the light emitting diode is operated.

The bolt structure of the bulb coincides with the nut structure groove of the standard incandescent lamp standard socket, and when the groove is turned to the right, the electrode of the bulb and the electrode of the socket come into contact with each other so that electricity is supplied.The nut of the socket and the bolt structure of the bulb are different. Illuminating the incandescent bulb and the fluorescent lamp built in the ballast by the role of the contact of the electrode, since the direction of light emission is all directions, there was no problem even if the bulb is rotated at any position.

However, unlike the filament of the incandescent bulb, the light emitting diode bulb is a single semiconductor chip and cannot have a light quantity corresponding to 100 W of the incandescent bulb. Therefore, it is necessary to fix several semiconductor chips to the PCB and flow current to the transparent electrode (ITO) or the electrode. A structure having is inevitable.

Therefore, it is inevitable to produce LED bulbs in a predetermined direction, such as top-down or side-by-side, while top-down tops have no problem in producing the bolt structure of an existing bulb, but in the case of side-by-side, it is impossible to match the fixed position and the side lighting direction. there is a problem.

In order to solve this problem, it is possible to rotate the light emitting surface of the light emitting diode printed circuit board from the lower side to the side, but the heat dissipation of the second heat sink by the first heat dissipation and heat pipe heat conduction that can stably dissipate heat generated by the light emitting diode. As a result, the light emitting diode bulb can be used like a conventional incandescent lamp at room temperature. Particularly, when the light emitting diode bulb is used as a side view, if the bolt structure of the existing incandescent bulb is adopted, it is inserted into the socket and rotated to the right, so it is impossible to match the fixed position and the direction of orientation. If the three electrodes are pressed by pressing a button without releasing the pressed button, the uneven grooves of the three electrodes are positioned in the nut groove of the socket to fix the light emitting diode bulb in an arbitrary position and the light emitting direction.

In order to use LED bulbs with compatibility with existing bulbs, downlight and directional bulbs must be produced and supplied separately. The bolt structure of the existing incandescent bulb can be applied only in the top-down case, and in the case of the lateral type, the bolt structure bulb is in the direction of illumination. There are many different factors from existing bulbs, such as the problem of not being able to select in the desired direction, which can solve the inefficient problem that the supplier or user must suffer. In particular, in parallel with solving the heat problem of the light emitting diode bulb, the direction of illumination can be adjusted laterally and downwardly, and if the bulb can be fixed beyond the nut position of the socket, it can be completely compatible with any existing lighting fixtures. It will be able to revitalize the light emitting diode market such as lighting and reflector lamp lighting.
