Description

本発明は、固体照明灯具に関し、特に配光分布を変換できるランプカバーを具備する固体照明灯具に関するものである。   The present invention relates to a solid illumination lamp, and more particularly to a solid illumination lamp including a lamp cover that can change a light distribution.

固体照明光源は、電流を特定波長範囲内の光に転換することができる半導体素子であり、高輝度、低作動電圧、低消費電力、集積回路にマッチングし易く、駆動し易く、長寿命などの利点を有するため、光源として照明領域で広く用いられている（非特許文献１を参照）。   Solid-state illumination light source is a semiconductor element that can convert current into light within a specific wavelength range, such as high brightness, low operating voltage, low power consumption, easy to match with integrated circuits, easy to drive, long life, etc. Since it has an advantage, it is widely used in the illumination area as a light source (see Non-Patent Document 1).

固体照明光源は点光源に近似するため、それを素子に製作する際に、通常一次光学設計を行って、その配光分布を変換する。常用のＬＥＤ素子の配光曲線はランバート（Ｌａｍｂｅｒｔ）分布を呈し、即ち前記ＬＥＤ素子の半値全幅（Ｆｕｌｌ Ｗｉｄｔｈ ａｔ Ｈａｌｆ Ｍａｘｉｍｕｍ，ＦＷＨＭ）は±６０°以内或いは１２０°である。前記ＬＥＤ素子を照明装置に製作する際に、前記照明装置の配光曲線を変換する必要があれば、通常二次光学設計（例えば、光学レンズなどの光学素子を添加すること）によって、前記配光曲線を変換して元のランバート分布と区別する。   Since a solid-state illumination light source approximates a point light source, when it is manufactured as an element, a primary optical design is usually performed to convert the light distribution. The light distribution curve of a normal LED element exhibits a Lambert distribution, that is, the full width at half maximum (FWHM) of the LED element is within ± 60 ° or 120 °. When it is necessary to convert the light distribution curve of the illuminating device when the LED element is manufactured in the illuminating device, the distribution is usually performed by secondary optical design (for example, adding an optical element such as an optical lens). The light curve is transformed to distinguish it from the original Lambertian distribution.

しかし、照明装置の配光曲線は光学レンズの形状によって決めるため、異なる配光曲線を発生させるために、異なる形状の光学レンズを製作しなければならなく、製造コストを増加させる。   However, since the light distribution curve of the illumination device is determined by the shape of the optical lens, it is necessary to manufacture optical lenses having different shapes in order to generate different light distribution curves, which increases the manufacturing cost.

本発明は、従来の問題点に鑑みてなされたものであり、光源の配光分布を変換できるランプカバーを具備する固体照明灯具を提供することを目的とする。   The present invention has been made in view of the conventional problems, and an object of the present invention is to provide a solid state illumination lamp including a lamp cover that can convert the light distribution of a light source.

前記問題を解決するために、本発明に係る固体照明灯具は、キャリアー、前記キャリアーの上に設けられている複数の固体照明光源及び前記固体照明光源を覆うランプカバーを備えてなる。前記固体照明光源が出射する光線は、前記ランプカバーを通過して対象物に照射される。前記ランプカバーはその自体に一体成形される少なくとも１つの光学素子を備え、前記光学素子は前記固体照明光源の上方に設置されて、前記固体照明光源が出射する光線の配光分布を変換し、且つ異物などが前記固体照明灯具の中に入ることを防止する。   In order to solve the above-described problem, a solid-state illumination lamp according to the present invention includes a carrier, a plurality of solid-state illumination light sources provided on the carrier, and a lamp cover that covers the solid-state illumination light source. The light beam emitted from the solid-state illumination light source passes through the lamp cover and is irradiated onto the object. The lamp cover includes at least one optical element integrally formed with the lamp cover, and the optical element is installed above the solid-state illumination light source to convert a light distribution of light emitted from the solid-state illumination light source. In addition, foreign matter or the like is prevented from entering the solid illumination lamp.

従来の技術に比べて、本発明の固体照明灯具において、異なる光学素子を備えるランプカバーを取り換えることにより、環境に応じて異なる配光分布を形成する。即ち、本発明において、あらためて灯具を設計する必要がなく、異なる光学素子を備えるランプカバーを取り換えるだけで、異なる環境の要求に満たすことができる。これにより、特定の配光分布を得るために、あらためて照明装置を設計しなくてもよく、照明装置の製造コストを下げる。 Compared with the prior art, in the solid state lighting fixture of the present invention, a different light distribution is formed according to the environment by replacing the lamp cover provided with different optical elements. That is, in the present invention, it is not necessary to design a lamp again, and it is possible to meet the requirements of different environments by simply replacing the lamp cover having different optical elements. Thereby, in order to obtain a specific light distribution, it is not necessary to design a lighting device again, and the manufacturing cost of the lighting device is reduced.

また、本発明において、溶融したプラスチック材料を射出成形するか或いは熱可塑性プラスチックを熱成形することにより、前記ランプカバー及び前記光学素子を一体成型するので、材料及び製作時間を節約する。   Further, in the present invention, the lamp cover and the optical element are integrally formed by injection molding of a molten plastic material or thermoforming of a thermoplastic plastic, thereby saving material and manufacturing time.

また、本発明のランプカバーは従来の二次光学設計の工程を省略した上で、防塵の効果も達成することができる。   In addition, the lamp cover of the present invention can achieve a dustproof effect while omitting the conventional secondary optical design process.

本発明の実施形態に係るランプカバーは、街路灯、電気スタンド及び展示用灯などの異なる照明装置に応用されることができる。図１に示したように、前記ランプカバー１０は、少なくとも１つの光学素子１０１を備え、前記光学素子１０１は前記ランプカバー１０と一体成形される。好ましくは、前記光学素子１０１を前記ランプカバー１０の上方に設置する。   The lamp cover according to the embodiment of the present invention can be applied to different lighting devices such as street lamps, desk lamps, and exhibition lamps. As shown in FIG. 1, the lamp cover 10 includes at least one optical element 101, and the optical element 101 is integrally formed with the lamp cover 10. Preferably, the optical element 101 is installed above the lamp cover 10.

図２及び図３に示したように、前記光学素子１０１は、入光面１０１１及び出光面１０１２を含む。前記光学素子１０１は、非対称的或いは対称的であることができ、固体照明灯具１の固体照明光源２０が出射する光線の配光分布を調整するために用いられる。前記光学素子１０１が非対称的な光学レンズである場合、前記固体照明光源２０の照射パターン（ｉｌｌｕｍｉｎａｔｉｏｎ ｐａｔｔｅｒｎ）は長方形である。前記光学素子１０１が対称的な光学レンズである場合、前記固体照明光源２０の照射パターンは円形である。   As shown in FIGS. 2 and 3, the optical element 101 includes a light incident surface 1011 and a light output surface 1012. The optical element 101 can be asymmetrical or symmetric and is used to adjust the light distribution of the light rays emitted from the solid-state illumination light source 20 of the solid-state illumination lamp 1. When the optical element 101 is an asymmetric optical lens, the illumination pattern of the solid-state illumination light source 20 is rectangular. When the optical element 101 is a symmetric optical lens, the irradiation pattern of the solid-state illumination light source 20 is circular.

前記固体照明光源２０が出射する光線は、前記ランプカバー１０を通過してから対象物を照射する。前記ランプカバー１０は、塵などの異物が前記固体照明灯具１の中に入ることを防止することができる。   The light beam emitted from the solid-state illumination light source 20 irradiates the object after passing through the lamp cover 10. The lamp cover 10 can prevent foreign matters such as dust from entering the solid state lighting device 1.

もし前記光学素子１０１がレンズであれば、前記レンズは前記固体照明光源２０の出光面に設けられ、前記固体照明光源２０が出射する光線は前記レンズを通過して出射される。前記固体照明光源２０が出射する光線は前記レンズの入光面１０１１及び出光面１０１２を通過した後、その出射角度が変換されるので、配光分布を変換する目的を達成する。   If the optical element 101 is a lens, the lens is provided on the light output surface of the solid-state illumination light source 20, and the light beam emitted from the solid-state illumination light source 20 is emitted through the lens. Since the light emitted from the solid-state illumination light source 20 passes through the light incident surface 1011 and the light output surface 1012 of the lens, and the light emission angle is converted, the object of converting the light distribution is achieved.

本発明の第一実施形態に係るランプカバー１０は、プラスチック射出成形或いはプラスチック熱成形によって、前記光学素子１０１を前記ランプカバー１０とともに一体成形するので、コスト及び製作時間を節約する利点を有する。   The lamp cover 10 according to the first embodiment of the present invention has an advantage of saving cost and manufacturing time because the optical element 101 is integrally formed with the lamp cover 10 by plastic injection molding or plastic thermoforming.

本実施形態が採用する射出成形方法とは、加熱溶融されたプラスチック材料を金型内に射出注入し、冷却・固化させることによって、成形品を得る方法であり、前記成形品の厚みは射出注入時間の増加に従って次第に厚くなる。前記溶融プラスチック材料は、剪断速度が増すとともに粘度が減少する非ニュートン流体であるため、本実施形態において、加熱溶融させたプラスチック材料を超高速度で射出注入し、且つ剪断稀薄（ｓｈｅａｒ ｔｈｉｎｎｉｎｇ）及び剪断二重効果により溶融プラスチック材料の粘度を低減し、溶融プラスチック材料の流動性を高め、射出圧力を下げて、さらに薄型化成型の目的を達成する。即ち、本発明はサイズが精確であり、光学素子を含むランプカバーを製造することができる。   The injection molding method employed in the present embodiment is a method of obtaining a molded product by injecting and injecting a heat-melted plastic material into a mold, and cooling and solidifying, and the thickness of the molded product is injection injected. Thicken gradually as time increases. Since the molten plastic material is a non-Newtonian fluid whose viscosity decreases as the shear rate increases, in this embodiment, the heated and melted plastic material is injected and injected at a very high speed, and shear thinning and The shear double effect reduces the viscosity of the molten plastic material, increases the fluidity of the molten plastic material, lowers the injection pressure, and achieves the purpose of further thinning molding. That is, the present invention is accurate in size and can manufacture a lamp cover including an optical element.

本実施形態が採用する熱成型方法とは、金型内に熱可塑性プラスチックを充填して、この熱可塑性プラスチックが加熱される際に成形される方法である。前記熱成型方法において、前記金型を均一に加熱し且つ保温することを必要とする。しかも、熱可塑性プラスチックを加熱して軟らかい状態で金型に押しつけるので、成形品は永久に硬化される。本発明は、加熱加圧の方式で、サイズが精確であり、光学素子を含むランプカバーを製造することができる。 The thermoforming method employed in the present embodiment is a method in which a thermoplastic resin is filled in a mold and molded when the thermoplastic plastic is heated. In the thermoforming method, the mold needs to be heated uniformly and kept warm. Moreover, since the thermoplastic plastic is heated and pressed against the mold in a soft state, the molded product is permanently cured. The present invention can manufacture a lamp cover including an optical element with a precise size by a heating and pressing method.

図４及び図５に示したように、本発明の実施形態に係る固体照明灯具１は、ランプカバー１０、１つ或いは複数の固体照明光源２０及び１つのキャリアー（ｂｒａｃｋｅｔ）３０を備える。前記ランプカバー１０は、少なくとも１つの光学素子１０１を含む。前記ランプカバー１０は前記キャリアー３０の上方に設けられ、且つ前記ランプカバー１０及び前記キャリアー３０は、複数の係止部材５０を介して一体に固定される。 As shown in FIGS. 4 and 5, the solid state illumination lamp 1 according to the embodiment of the present invention includes a lamp cover 10, one or a plurality of solid state illumination light sources 20, and a single carrier 30. The lamp cover 10 includes at least one optical element 101. The lamp cover 10 is provided above the carrier 30, and the lamp cover 10 and the carrier 30 are integrally fixed via a plurality of locking members 50.

また、前記光学素子１０１の出光面１０１２はサドル（ｓａｄｄｌｅ）状或いは砲弾状であってもよい。前記光学素子１０１の入光面１０１１は、非対称的な曲面或いは砲弾状であってもよい。   The light exit surface 1012 of the optical element 101 may have a saddle shape or a shell shape. The light incident surface 1011 of the optical element 101 may be an asymmetric curved surface or a shell shape.

本発明によれば、異なる光学素子１０１を備えるランプカバー１０を取り換えることにより、環境に応じて異なる配光分布を形成する。即ち、本発明において、あらためて灯具を設計する必要がなく、異なる光学素子を備えるランプカバーを取り換えるだけで、異なる環境の要求に満たすことができる。これにより、特定の配光分布を得るために、あらためて照明装置を設計しなくてもよく、照明装置の製造コストを下げる。 According to the present invention, by changing the lamp cover 10 having different optical elements 101, different light distributions are formed according to the environment. That is, in the present invention, it is not necessary to design a lamp again, and it is possible to meet the requirements of different environments by simply replacing the lamp cover having different optical elements. Thereby, in order to obtain a specific light distribution, it is not necessary to design a lighting device again, and the manufacturing cost of the lighting device is reduced.

以上、本発明の好適な実施形態について詳細に説明したが、本発明は前記実施形態に限定されるものではなく、本発明の範囲内で種々の変形又は改良が可能であり、該変形又は改良も、本発明の特許請求の範囲内に含まれることであるのが、いうまでもない。 The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the above-described embodiments, and various modifications or improvements can be made within the scope of the present invention. However, it goes without saying that it is included in the scope of the claims of the present invention.
