Description

本発明は、広角照明装置に関し、特に広角の照明効果を達成すると同時に、輝度及び光均一効果を高める広角照明装置に係わる。   The present invention relates to a wide-angle illuminating device, and more particularly to a wide-angle illuminating device that achieves a wide-angle illumination effect and at the same time enhances luminance and light uniformity effects.

近年、地球温暖化問題は日ごとに厳しい状況となり、各種の省エネ，ＣＯ２削減のエコ製品は益々重要視されている。電球について言うと、従来は白熱電球を使用していたが、白熱電球は発光過程に於いて、消費エネルギーのうちの９０％が熱エネルギーに転化してしまい、残りの１０％だけが光になり、そのため、発光効率が低く、エネルギーを無駄に消費している。 In recent years, the global warming problem has become more severe every day, and various types of energy-saving and CO 2 -reducing eco-products are becoming more important. Regarding incandescent bulbs, incandescent bulbs have been used in the past, but incandescent bulbs are converted into thermal energy in the light emission process, and only the remaining 10% becomes light. Therefore, the luminous efficiency is low and energy is wasted.

白熱電球の低発光効率から市場では白熱電球に代わる発光ユニットが発展してきている。そのうちの一つである発光ダイオード(Light Emitting Diode；LED)は、高輝度、省エネ、環境保護、使用寿命の長さという長所を備え、且つ製造過程では二酸化炭素の放出量が減り、コストを下げる他に、汚染を減らす目的を達成する。 Due to the low luminous efficiency of incandescent bulbs, light-emitting units that replace incandescent bulbs have been developed in the market. One of them, Light Emitting Diode (LED), has the advantages of high brightness, energy saving, environmental protection, and long service life, and the production process reduces carbon dioxide emissions and lowers costs. Another objective is to reduce pollution.

現在の技術であるLEDを光源とする電球のその主な構造は、ネジプラグ上に順に発光体と照明カバーを設置する。該発光体は平板状の回路基板構造及びその上に設置するLED発光ユニットを備える。 The main structure of a light bulb that uses LED as a light source, which is the current technology, is to install a light emitter and a light cover in order on a screw plug. The light emitter includes a flat circuit board structure and an LED light emitting unit installed thereon.
