Description

[Detailed description of the invention] [Industrial application field] The invention is used for crime prevention and automatic control.
It concerns LED (light emitting diode) lamps.

[Conventional technology] Conventional LED lamps consist of multiple visible light LEDs.
A circular board consisting of an array of is mounted on the stem,
This stem was welded to a glass bulb so that the substrate was housed inside, and the stem was evacuated and filled with a specified inert gas, as in the manufacture of a general incandescent light bulb, and the bulb was tipped off and fitted with a cap.

[Problems that the invention aims to solve] The conventional method of arranging visible light LEDs on a circular board
LED lamps emit visible light that stimulates the human eye when lit, and were primarily used for decoration and display purposes. For this reason, when used as a lamp for infrared light emitting devices for crime prevention or automatic control, conventional red
Even if LEDs are used, the irradiated light has too much visible light, and each LED emit different colors, so the irradiation to the light receiving device etc. is insufficient, and the infrared light emitting device The problem was that it was difficult to use as a system.

[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 the substrate is housed inside and filled with inert gas. In an LED lamp made of a chip-off glass bulb and a cap with a built-in series resistance element attached to the glass bulb by baking, an infrared ray is attached to the circular substrate.
The present invention provides an LED lamp that is characterized by arranging LEDs at arbitrary intervals and allowing the LED located approximately in the center to be used as a general visible light LED, and is mainly used for crime prevention and other purposes. It is suitable for automatic control, etc.

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

Figures 1 and 2 show an embodiment of the present invention, in which a plurality of infrared LEDs 2 are arranged at arbitrary intervals as light sources on a circular substrate 1 forming a series-connected power supply pattern. , the circular substrate 1 is mounted on a 2P stem 3, and this stem 3 is welded to the glass bulb 4 so that the circular substrate 2 is housed inside, similar to the manufacturing process of a general incandescent light bulb. After evacuating, inert gas is filled in, and chipped off, a base 5 containing a series resistor is bonded by baking.

Furthermore, in the LEDs arranged on the circular substrate 1,
LED2a located approximately in the center is a visible light LED.
It is possible to use this visible light
The LED is always on, making it easy to set the direction of irradiation to the light receiving device.

FIG. 3 shows another embodiment of the invention. LED 2 located approximately in the center of the circular board 1
Only a is a general visible light LED, and this visible light LED is arranged on a pattern circuit different from the infrared LED arranged on the power supply pattern of the circular board 1, and this circular board is connected to a 3P stem. 3 and different power supply lead wires 3a, 3 respectively.
The base 5 to be bonded by baking has two contacts and connects to the power supply lead wires 3a, 3b.
A device with a built-in series resistor 6 connected to each is used.

The contact 5a of the base 5 is made of a resilient conductive material, and is connected to the power supply lead wire 3a connected to the infrared LED, and the contact 5b is made of a resilient conductive material.
It is connected to the power supply lead wire 3b connected to the LED, and there is usually a gap between the contacts 5a and 5b, and these two contacts can be in a contact state or a non-contact state depending on how deep and shallow they are screwed into the socket. This switch switches the power supply.

The glass bulb 4 is molded with inner spatter 4a or the outer periphery covered with a black tube to prevent external light, and the shape of the cap 5 is E-26, B22D, etc. depending on the purpose of use. It shall be installed as appropriate.

[Function] The LED lamp of the present invention is mainly used in security devices, automatic control devices, etc., and irradiates infrared light to a light receiving device. LED2a located in the visible light
By using an LED, the light receiving device can be easily set to match the visible light irradiated by the LED.

In addition, by connecting a visible light LED and an infrared LED in parallel and attaching a cap with two contacts, when screwed deeply into the socket, two contacts 5a,
5b are in contact, turn on both the visible light LED and the infrared LED, set the light receiving direction according to the visible light, and after setting, if you do not need visible light, loosen the screws to the socket. By making it shallower, the contacts 5a and 5b of the base that were in contact with each other are separated by the restoring force of the contact 5a, and electricity is applied only from the contact 5a, causing only the infrared LED to light up and the visible light LED to turn off. .

[Effects of the invention] As explained above, the LED lamp of the invention has the following effects:
By using an infrared LED as a light source, it can be easily installed outdoors as an infrared light emitting device and can operate over a wide range of light receiving elements, making it possible to install a power source indoors and conduct long distance wiring, which is useful for crime prevention. It has excellent effects for various purposes.

Furthermore, a visible light LED is placed approximately in the center of the circular board.
By arranging the light-receiving element, the direction of the light-receiving element can be easily determined, and the light can also be turned off after setting by simply loosening the screw onto the socket.
