본 발명은 LED(light emitting diode)를 광원으로 하여 각종 상품의 브랜드나 상호 또는 심벌마크 등의 문자나 도안으로 된 광고내용을 확대 투사하여 벽면이나 천정 등의 피투사물체에 조명하므로서 상품 등을 선전광고하기 위한 조명장치에 관한 것으로, 보다 상세하게는 매장의 천정이나 진열장 또는 탁자 등에 간편하게 설치할 수 있도록 소형으로 형성되어 사용자로 하여금 손을 이용하여 안전하게 조명장치의 조명각도를 자유롭게 조절할 수 있도록 LED에서 발생되는 열을 공냉식으로 쉽게 방출시킬 수 있도록 하는 열방출부재를 포함하고 있는 LED 조명장치에 관한 것이다.According to the present invention, an LED (light emitting diode) is used as a light source, and the advertisement contents in the form of letters or designs, such as a brand, a trade mark, or a symbol mark, of various products are enlarged and projected to illuminate a projected object such as a wall or a ceiling, thereby promoting a product or the like. The present invention relates to a lighting device for advertising, and more particularly, it is formed in a small size so that it can be easily installed on a ceiling, a showcase, or a table of a store, and is generated from an LED so that a user can freely adjust the lighting angle of the lighting device safely by using a hand. The present invention relates to an LED lighting device including a heat dissipation member for easily dissipating heat by air cooling.

일반적으로 백화점이나 할인마트점 및 상품판매점 등에서 상품의 브랜드나 로고 등을 매장의 벽면이나 천정 등에 표현하기 위해서는 브랜드나 로고가 인쇄된 광고판이나 플래카드(placard) 등을 벽면이나 천정에 부착시키는 방법과, 페인트로 벽면이나 천정 등에 페인팅하는 방법 등이 있으나, 이러한 방법들은 판매하고자 하는 상품이 바뀔 때마다 교체하여야 하는 관점에 볼 때 매우 비경제적, 비효율적인 문제와 함께 매장의 벽면 및 천정을 훼손시킬 수 있다는 이유로 인하여 각 업소에서는 상기와 같은 방법들을 채택하지 않고 있는 실정이다.In general, in order to express a brand or logo of a product on a wall or a ceiling of a store in a department store, a discount mart store, or a merchandise store, a billboard or a placard on which a brand or logo is printed is attached to a wall or a ceiling; There is a method of painting on the walls or ceilings with paint, but these methods can damage the walls and ceilings of the store with very uneconomical and inefficient problems from the point of view of replacing them every time the product to be sold changes. For these reasons, each business does not adopt the above methods.

따라서 위와 같은 문제를 해결하기 위한 방안으로서, 본 발명의 발명자에 의하여 실용신안등록 제97316호 및 제100706호의 조명장치가 제안된 바 있는데, 이들 선행기술들은 조명장치의 광원을 백열전구를 사용하고 있기 때문에 백열전구에서 발생되는 고열로 인하여 매장 내부의 온도를 상승시키게 되는 문제와 함께 조명장치의 케이스가 손으로는 만질 수 없을 정도로 뜨거워 조명각도의 조절이 용이하지 못하다는 단점이 있어 실용화되지 못하였다.Therefore, as a solution to the above problems, the inventors of the Utility Model Registration Nos. 97316 and 100706 have been proposed by the inventor of the present invention, these prior art uses the incandescent bulb as a light source of the lighting device Due to the high temperature generated in the incandescent bulb to increase the temperature inside the store, the case of the lighting device is so hot that you can not touch by hand, there is a disadvantage that it is not easy to adjust the lighting angle was not practical.

Although it is applied in various ways, in the case of LED that emits strong light, the heat generated during lighting is relatively high. In other words, in the case of LEDs with high light intensity, the heat generated when lighting for a long time is weaker than the heat generated from an incandescent lamp, but it is difficult to apply to a device that is frequently touched by a user because it is too hot to be touched by a person. It was.

본 발명은 수 와트 내지 수십 와트의 전력으로 강한 빛을 발하게 되는 LED를 이용하여 문자나 도안을 투사하여 그 투사된 문자, 도안 등을 피투사물체인 벽면이나 천정 또는 바닥에 선면하게 나타나도록 조명하는 조명장치를 구성함에 있어, 조명장치의 케이스 내부에 장착된 LED에서 발생되는 열을 공냉식으로 방출시킬 수 있도록 구성하므로서 사용자가 조명장치의 조명각도를 조절하고자 할 때 조명장치를 손으로 만지게 되더라도 뜨거움을 느끼지 않도록 하여 사용자로 하여금 안심하고 조명장치를 손으로 만져 조명각도를 조절하는 동작으로 조명장치로부터 투사되는 문자나 도안 등의 투사위치를 수시로 변경하여 상품의 선전효과를 높일 수 있도록 하는데 목적을 두고 발명한 것이다.The present invention is to illuminate a character or pattern by using a LED that emits strong light at a power of several watts to several tens of watts to illuminate the projected characters, patterns, etc. to appear on the wall, ceiling or floor of the projected object. In configuring the device, the heat generated from the LED mounted inside the case of the lighting device can be air-cooled, so that when the user wants to adjust the lighting angle of the lighting device, the user does not feel the heat even when the lighting device is touched by hand. The present invention was designed to enhance the propaganda effect of a product by changing the projection position of a character or a pattern projected from the lighting device at any time by controlling the lighting angle by touching the lighting device with a user's hand in peace. will be.
