Description

本考案はLED式発光ユニット及び照明装置に関する。   The present invention relates to an LED type light emitting unit and a lighting device.

LED等を用いた蛍光灯型の照明装置における従来の点灯方式は、AC−DCコンバータを用いた、いわゆるスイッチング方式(定電流型)のものが広く知られている。   As a conventional lighting method in a fluorescent lamp type lighting device using an LED or the like, a so-called switching method (constant current type) using an AC-DC converter is widely known.

従来の方式によれば、最大定格での使用が前提となるため、発熱量も必然時に多くなり、また電源設備の定格分しか電流を流せないため非効率的であった。
また、LEDを並列に接続するため、LEDの増加にあわせて、回路全体に流す電流も増加させる必要が生じる。
According to the conventional method, since it is assumed to be used at the maximum rating, the amount of heat generation is inevitably increased, and current can only be supplied for the rated power supply facilities, which is inefficient.
Further, since the LEDs are connected in parallel, it is necessary to increase the current flowing through the entire circuit as the number of LEDs increases.

また、従来市場に出ているLED蛍光管並びにLED電球はLEDの発熱を抑えるためヒートシンクや放熱口を設けてあることが一般的である。
したがって、LEDの発熱を抑えることができれば、ヒートシンクの設置分だけスペースを節約したり、前記放熱口を設けないことで埃の侵入等による故障を回避することが期待できる。
Further, LED fluorescent tubes and LED bulbs on the market are generally provided with a heat sink and a heat radiation port in order to suppress the heat generation of the LED.
Therefore, if the heat generation of the LED can be suppressed, it can be expected that a space is saved by the amount of heat sink installed, or failure due to dust intrusion is avoided by not providing the heat radiation port.

上記課題を解決すべくなされた本願の第1考案は、LEDを用いた発光ユニットであって、複数のLEDが直列接続してなる発光手段と、前記発光手段に応じた電圧及び電流を供給するチャージ/ディスチャージ式の供給回路と、からなることを特徴とする、発光ユニットを提供するものである。
また、本願の第2考案は、前記供給回路を長尺状の基板に形成し、前記発光手段を構成するLEDを、前記基板上に間隔を設けて配置してなる、前記第1考案に記載の発光ユニットを提供するものである。
また、本願の第3考案は、前記第2考案に記載の発光ユニットを蛍光管と同形状の管材に収納して、該管材の内部を完全に閉塞してなる、照明装置を提供するものである。
また、本願の第4考案は、前記第2考案に記載の発光ユニットを、筒材に収納し、前記筒材の両端を絶縁材で被覆することで筒材内部を閉塞してなる、照明装置を提供するものである。
The first device of the present application to solve the above problems is a light emitting unit using LEDs, and a light emitting means in which a plurality of LEDs are connected in series, and a voltage and a current according to the light emitting means are supplied. The present invention provides a light emitting unit comprising a charge / discharge type supply circuit.
The second device of the present application is the first device, wherein the supply circuit is formed on a long substrate, and the LEDs constituting the light emitting means are arranged on the substrate with a space therebetween. The light emitting unit is provided.
Further, the third device of the present application provides an illumination device in which the light emitting unit described in the second device is housed in a tube material having the same shape as a fluorescent tube, and the inside of the tube material is completely closed. is there.
A fourth device of the present application is a lighting device in which the light emitting unit according to the second device is housed in a cylindrical material, and both ends of the cylindrical material are covered with an insulating material to block the inside of the cylindrical material. Is to provide.

本発明によれば、以下の効果のうち、少なくとも何れか一つを奏する。
(1)LEDの点灯に必要な分だけ、電圧及び電流を供給できる。
(2)LEDの数に応じて無理のない電圧及び電流供給が可能であるため、発熱を極力抑えることが出来る。
(3)発熱対策としてヒートシンクを設ける必要が無い為、装置全体の容量を抑え、低コスト化に寄与する。
(4)発熱対策として放熱口を設ける必要が無い為、埃の侵入等を避け、安全性の向上に寄与する。
According to the present invention, at least one of the following effects is achieved.
(1) Voltage and current can be supplied as much as necessary for lighting the LED.
(2) Since a reasonable voltage and current can be supplied according to the number of LEDs, heat generation can be suppressed as much as possible.
(3) Since it is not necessary to provide a heat sink as a countermeasure against heat generation, the capacity of the entire apparatus is suppressed, contributing to cost reduction.
(4) Since it is not necessary to provide a heat radiating port as a countermeasure against heat generation, it prevents dust from entering and contributes to improving safety.
