Description

本考案は、光源モジュールに関するもので、特に一種発光ダイオードの光源モジュールに係わる The present invention relates to a light source module, and more particularly to a light source module of a kind of light emitting diode.

発光ダイオード(light emitting diode, LED)は、一種の半導体部品であり、主に半導体化合物によって電気エネルギーを光エネルギーに転換して発光効果を達成する。それにより、寿命が長く安定性が向上し、電気消費量が小さくなる長所を備え、現在では住居、オフィス、室外及び携帯照明に広く応用され、蛍光灯及び白熱電球等従来の非指向性発光源から移行している。 A light emitting diode (LED) is a kind of semiconductor component that achieves a light emitting effect by converting electrical energy into light energy mainly by a semiconductor compound. As a result, it has the advantages of long life, improved stability and reduced electricity consumption, and is now widely applied in residential, office, outdoor and portable lighting, and conventional non-directional light sources such as fluorescent lamps and incandescent lamps Have migrated from.

発光ダイオードは点状光源で且つ高指向性を備えるため、発光ダイオードの照射面は公知の光源と比較して狭くなる。そのため、短距離及び小エリアの照明、例として卓上ライトに適用される。 Since the light emitting diode is a point light source and has high directivity, the irradiation surface of the light emitting diode is narrower than that of a known light source. Therefore, it is applied to short-distance and small-area lighting, for example, table lamps.

発光ダイオードをその他の照明具、例として白熱電球もしくはキャンドルライトに応用するため、多くのメーカーでは複数個の発光ダイオードを組み立てたり配列したりして発光を集中させ照射強度が小さくなりすぎる問題を補強している。 In order to apply light-emitting diodes to other lighting fixtures, such as incandescent bulbs or candlelights, many manufacturers reinforce the problem that the light intensity becomes too low by assembling and arranging multiple light-emitting diodes to concentrate light emission. is doing.
