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 have multiple LED lamps on a circular substrate.
LEDs are connected in series and arranged and mounted on a stem.The stem is welded to a glass bulb, evacuated as in the manufacture of incandescent light bulbs, filled with a specified inert gas, chipped off, and fitted with a cap. It is something.

When you turn on such an LED lamp, all
The LEDs emitted light at the same time, and by arranging two types of LEDs of different colors on a circular board, it was possible to light up in mixed colors. It was also possible to blink the light through an external switching device or the like.

[Problems that the invention aims to solve] In conventional LED lamps, each LED was arranged in series, so it was not possible to control the power supply to each individual LED, and the lamp had to be switched in order to turn on or blink in two colors. Since the equipment, etc. had to be installed externally, equipment costs, construction costs, etc. were required. In addition, the color of the light emitted when it is lit is only a fixed color, which is monotonous and does not change, so there are problems such as it is difficult to obtain an eye-catching lighting effect even if it is used for decoration. It was hot.

[Means for Solving the Problems] As a specific means for solving the above-mentioned problems, the present invention provides a circular substrate on which a plurality of LEDs are arranged, and an inert gas in which the circular substrate is housed. In an LED lamp consisting of a glass bulb sealed with a glass bulb and a base baked and bonded to the glass bulb,
Ring each LED arranged on the circular board
The present invention provides an LED lamp that is connected to a blinking controller with a built-in IC, and is an eye-catching LED lamp that blinks or lights up in a mixed color without installing a switching device.

[Function] The LED lamp of the present invention is arranged on a circular substrate.
By connecting the LEDs individually to a blinking controller,
The blinking controller has a built-in ring IC to control individual LEDs.
It lights up by controlling the order of power supply to the
The switching speed of the lighting is adjusted by a volume or a fixed resistor to perform blinking or lighting in mixed colors to enhance the lighting effect.

[Example] Next, the present invention will be explained in detail based on the illustrated example.

1 to 3 show an embodiment of the LED lamp of the present invention, in which a plurality of LEDs 1 are arranged on a circular substrate 2 at appropriate intervals, and
The LEDs are each independently connected to a blinking controller 3, and the circular board 2 is mounted on a stem 4, and the blinking controller 3 is also connected to a power supply lead wire 4a and attached to the stem 4, and the circular board 2 and The stem 4 is welded to the glass bulb 5 so that the blinking controller 3 is housed inside, and the glass bulb is evacuated in the same manner as in the manufacturing process of a general incandescent light bulb, filled with a predetermined inert gas, and then chipped off. 5 and a base 6 bonded by baking.

The blinking controller 3 has a built-in ring IC 3a and a volume 3b, and the ring IC 3a sequentially controls the power supply order to each of the LEDs 1 according to the setting, and the volume 3 controls the power supply switching speed.
b, or is set by a fixed resistor, etc. Further, the blinking controller 3 may be a hybrid IC having a blinking circuit or a device mounted on the circular substrate 2.
It is also possible to configure a control pattern circuit formed by disposing chip parts such as IC chips and provide it integrally with the circular substrate.

FIG. 4 shows another embodiment of the present invention, in which an LED 1 is placed approximately in the center of the circular substrate.
Only the connection line a is directly connected to the power supply lead wire 4a without being connected to the blinking controller 3, and the rest is the same as the embodiment described above. The LED 1a located approximately in the center is always lit, and the LEDs arranged around it are lit in sequence.

Incidentally, the LEDs 1 are arranged to emit light of different colors to enable mixed color lighting or multicolor lighting. Further, the glass bulb 5 may be round, T-shaped, or R-shaped, with or without a reflective surface 5a, depending on the conditions of use.

[Effects of the invention] As explained above, the LED lamp of the invention has the following effects by connecting each LED to a blinking controller.
Individual switching without the use of external switching devices, etc.
Since the LED is lit under the control of a blinking controller, there are many variations in lighting in mixed colors using two types of LEDs of different colors, and since blinking can be easily done, it can be used as a decorative light for display purposes, which was not possible before. It has the excellent effect of It can function in the same way as conventional emergency rotating lights, and can be used in a wide range of fields, not just as a replacement for conventional products.
In addition, like regular incandescent light bulbs, it is filled with inert gas, making it a long-life LED lamp.
