Abstract

PROBLEM TO BE SOLVED: To provide an LED lamp which can use an existing lighting system for a fluorescent lamp, and can emit light in concentration only from a part.SOLUTION: The LED lamp (light-emitting diode) 1 includes a cylindrical cover 2, and bases 4 fitted to either end of the cover 2 and each having a terminal 3 into which a socket of a lighting system is inserted. Inside the cover 2, a substrate 5 with a V-shaped cross section is provided in a length direction of the cover 2. On opposed faces making a V-shape of the substrate 5, a plurality of LED elements 6 are arranged.

Description

本発明は、LED(light−emitting diode)素子を光源とするLEDランプに関する。   The present invention relates to an LED lamp using an LED (light-emitting diode) element as a light source.

現在幅広く利用されているランプである蛍光灯の代わりに、近年LED(light−emitting diode)素子を光源とするLEDランプが使用されるようになってきている。   In recent years, LED lamps using light-emitting diode (LED) elements as light sources have been used in place of fluorescent lamps that are widely used at present.

既存の蛍光灯用の照明装置にそのまま使えるようにした蛍光灯型LEDランプが特許文献1などに示されている。関連技術の一例のLEDランプは、蛍光灯と同じく円筒形状をしたカバーの内部に、矩形状の基板がカバーの長手方向に沿って配置されている。そして、基板には、LED素子が等間隔に複数配置されている。このようなLEDランプと、交流電圧を直流電圧に変換する変換回路を有する変換ユニットとが、蛍光灯用照明装置のソケット同士の間に直列に配置されている。このようにすることで、既存の蛍光灯用照明装置にLEDランプを使用することができる。   Patent Document 1 discloses a fluorescent lamp type LED lamp that can be used as it is in an existing fluorescent lamp illumination device. In the LED lamp as an example of the related art, a rectangular substrate is disposed along the longitudinal direction of the cover inside a cylindrical cover similar to a fluorescent lamp. A plurality of LED elements are arranged at equal intervals on the substrate. Such an LED lamp and a conversion unit having a conversion circuit for converting an AC voltage into a DC voltage are arranged in series between the sockets of the fluorescent lamp illumination device. By doing in this way, an LED lamp can be used for the existing illuminating device for fluorescent lamps.

特開2010−192224号公報JP 2010-192224 A

上述の特許文献1のLEDランプでは、一般的な蛍光灯の代わりにはなるが、蛍光灯全体ではなく、蛍光灯のある一部分から集中して光を放出するようなアパーチュア蛍光灯の代わりにはならない。   In the above-mentioned LED lamp of Patent Document 1, instead of a general fluorescent lamp, instead of an entire fluorescent lamp, instead of an aperture fluorescent lamp that emits light concentratedly from a certain part of the fluorescent lamp, Don't be.

本発明の目的は、光を一部分から集中して放出させることは困難である、といった課題を解決するLEDランプを提供することである。   The objective of this invention is providing the LED lamp which solves the subject that it is difficult to concentrate and discharge light from one part.

本発明のLEDランプ(light−emitting diode)には、円筒状のカバーと、カバーの両端に設けられ、照明装置のソケットに挿入される端子を有する口金とが設けられている。また、カバーの内部には、断面がV字状をした基板がカバーの長手方向に設けられており、V字状をした基板が向き合う面には、複数のLED素子が配置されている。   The LED lamp (light-emitting diode) of the present invention is provided with a cylindrical cover and a base having terminals provided at both ends of the cover and inserted into sockets of the lighting device. Further, a substrate having a V-shaped cross section is provided inside the cover in the longitudinal direction of the cover, and a plurality of LED elements are arranged on the surface where the V-shaped substrate faces.

本発明によれば、既存の蛍光灯用照明装置を使用でき、かつ、光を一部分から集中して放出させることができる。   According to the present invention, an existing fluorescent lamp illumination device can be used, and light can be concentrated and emitted from a part.

本発明に係るLEDランプの一実施形態の概略構成図であり、(a)はLEDランプの断面の概略構成図、(b)は(a)の矢印Aの方向から見た概略構成図である。It is a schematic block diagram of one Embodiment of the LED lamp which concerns on this invention, (a) is a schematic block diagram of the cross section of a LED lamp, (b) is a schematic block diagram seen from the direction of arrow A of (a). .

以下に、添付の図面に基づき、本発明の実施の形態を説明する。なお、同一の機能を有する構成には添付図面中、同一の番号を付与し、その説明を省略することがある。   Embodiments of the present invention will be described below with reference to the accompanying drawings. In addition, the same number is attached | subjected to the structure which has the same function in an accompanying drawing, and the description may be abbreviate | omitted.

図1は、本発明に係るLEDランプの一実施形態の概略構成図であり、(a)はLEDランプの断面の概略構成図、(b)は(a)の矢印Aの方向から見た概略構成図である。なお、図1(b)では、内部構造が分かるように、カバー2や口金4を一部省略している。   FIG. 1 is a schematic configuration diagram of an embodiment of an LED lamp according to the present invention, where (a) is a schematic configuration diagram of a cross section of the LED lamp, and (b) is a schematic diagram viewed from the direction of arrow A in FIG. It is a block diagram. In FIG. 1B, the cover 2 and the base 4 are partially omitted so that the internal structure can be seen.

本発明のLED(light−emitting diode)ランプ1は、円筒状のカバー2の両端に、端子3を有する口金4が設けられている。端子3は、不図示の蛍光灯用照明装置にLEDランプ1が取り付けられたときに、照明装置のソケットに差し込まれ、照明装置からソケットを介して電圧を供給されるとともに、LEDランプ1を照明装置内に保持する役割もある。   The LED (light-emitting diode) lamp 1 of the present invention is provided with a base 4 having terminals 3 at both ends of a cylindrical cover 2. The terminal 3 is inserted into a socket of the lighting device when the LED lamp 1 is attached to a fluorescent lamp lighting device (not shown), and a voltage is supplied from the lighting device through the socket, and the LED lamp 1 is illuminated. There is also a role to hold in the device.

LEDランプ1の内部には、断面がV字状をした基板5がLEDランプ1の長手方向に設けられている。そして、V字状の基板5の内側の面(基板5が向き合う面)に複数のLED素子6が配置されている。このLED素子6を基板5に配置する数を調整することで、LEDランプ1から発せられる光の明るさを調節することができる。   Inside the LED lamp 1, a substrate 5 having a V-shaped cross section is provided in the longitudinal direction of the LED lamp 1. A plurality of LED elements 6 are arranged on the inner surface of the V-shaped substrate 5 (surface on which the substrate 5 faces). The brightness of the light emitted from the LED lamp 1 can be adjusted by adjusting the number of the LED elements 6 arranged on the substrate 5.

また、LEDランプ1の内部には、端子3から供給される交流電圧を直流電圧に変換して基板5に供給する不図示の変換回路が設けられている。なお、この変換回路は、LEDランプ1に設けるのではなく、照明装置に設けても構わず、また、変換回路を有する変換ユニットを構成し、照明装置のソケット同士の間に、LEDランプ1と変換ユニットとを直列に配置し、直流電圧をLEDランプ1に供給するようにしても構わない。   In addition, a conversion circuit (not shown) that converts the AC voltage supplied from the terminal 3 into a DC voltage and supplies it to the substrate 5 is provided inside the LED lamp 1. Note that this conversion circuit may be provided in the lighting device instead of being provided in the LED lamp 1, and constitutes a conversion unit having a conversion circuit, and between the LED lamp 1 and the socket of the lighting device. You may make it arrange | position a conversion unit in series and supply a DC voltage to the LED lamp 1. FIG.

以上のようにして構成されたLEDランプ1は、V字状をした基板5の内側の面にLED素子6を配置することにより、LEDランプ1から広範囲に光が発せられるのではなく、基板5で挟まれた部分からLEDランプ1の外部に光を発することができる。また、LEDランプから広範囲に光を発するためには、特許文献1のように矩形状をした基板にLED素子を配置することが好ましい。しかし、本発明のように、LEDランプ1のある一部分の狭い範囲から集中して光を発したい場合は、光を発したい部分にあわせて矩形状の基板を小さくするよりも、V字状の基板5を用いるほうが、多くのLED素子6を基板5に配置することができるので、LEDランプ1のある一部分(LEDランプ1の基板5で挟まれている部分)から強い光を発することができる。   In the LED lamp 1 configured as described above, by disposing the LED element 6 on the inner surface of the V-shaped substrate 5, light is not emitted from the LED lamp 1 in a wide range, but the substrate 5 Light can be emitted to the outside of the LED lamp 1 from the portion sandwiched between the two. In addition, in order to emit light over a wide range from the LED lamp, it is preferable to dispose the LED element on a rectangular substrate as in Patent Document 1. However, as in the present invention, when it is desired to emit light concentrating from a small range of a part of the LED lamp 1, it is V-shaped rather than making a rectangular substrate smaller in accordance with the portion to emit light. When the substrate 5 is used, more LED elements 6 can be arranged on the substrate 5, so that a strong light can be emitted from a certain part of the LED lamp 1 (a part sandwiched between the substrates 5 of the LED lamp 1). .

また、本発明のLEDランプ1は、既存の蛍光灯用照明装置に使用することが可能なので、蛍光灯から本発明のLEDランプ1への交換が容易であり、LEDランプ用の照明装置を新たに購入したり設置をしたりする必要がない。   Moreover, since the LED lamp 1 of the present invention can be used for an existing fluorescent lamp illumination device, it is easy to replace the fluorescent lamp with the LED lamp 1 of the present invention, and a new LED lamp illumination device is provided. There is no need to purchase or install it.

なお、上述の説明では、いわゆる直管状のLEDランプとして説明したが、本発明はこれに限定されず、環状であっても、それ以外の形状であっても、本発明を利用できれば、いずれであっても構わない。   In the above description, a so-called straight tubular LED lamp has been described. However, the present invention is not limited to this, and any shape can be used as long as the present invention can be used regardless of whether it is annular or other shapes. It does not matter.
