본 고안은 전구 외주면의 1/2가량을 수은도층을 형성하여 필라멘트의 발광빛을 반사시키도록한 종래의 것에 있어서, 전구내부의 필라멘트 하방으로 볼록렌즈와 반사구를 장설하여 필라멘트의 발광빛과 수은도층의 반사빛을 볼록렌즈가 반사구에 집조(集照)되게 한다음 집조된 불빛이 전구의 확대부 내면에 의하여 재반사되도록 하므로서 좀더 밝은빛을 비추도록한 조명구를 제공하기 위한 것이다.According to the present invention, about half of the outer circumferential surface of the bulb is formed of a mercury coating layer to reflect the emitted light of the filament. The convex lens and the reflector are installed below the filament inside the bulb to emit the filament's emitted light and mercury. The convex lens is focused on the reflector and then the reflected light is reflected back by the inner surface of the enlarged part of the bulb, thereby providing a brighter light.

종래의 전구외주면에 수은도층을 하여 필라멘트의 발광빛을 반사시켜 밝은빛을 내도록한것은 통상 직접조명방식을 채택한 것이기 때문에 밝은 빛이 넓게확산되지 못하여 조명면적이 한정되는 결점이 있는 것이었다.The conventional mercury coating layer on the outer circumferential surface of the bulb reflects the emitted light of the filament to produce bright light, which is a direct lighting method. Therefore, the bright light cannot be widely spread, and the lighting area is limited.

본 고안은 이와 같은 종래의 결점을 제거하여 전구가 지닌 용량보다는 더 밝은 빛으로 넓게확산시켜 비추도록한 것으로서 이하도면에 따라 상세히 설명하면 다음과 같다. 그로우브(1)의 형상을 위는 좁고 아래는 넓어지도록 협소부(1a)와 확대부(1b)로 형성하여 협소부(1a)내에 돌설된 스템관(2)에 필라멘트(3)를 장설하고 협소부(1a)의 외주면과 확대부(1b)의 상면에 수은도층(4)을 형성하여서 된 것에 있어서, 필라멘트(3)의 하방측이되는 협소부(1a)와 확대부(1b)의 중간부를 볼록렌즈(5)로 차단되게 형성하여 협소부(1a)내부를 진공화하였으며, 볼록렌즈(5) 하방에는 내부에 중공부(6)가 형성되고 외부벽면에 수은반사층(7)이 도착된 반사구(8)를 가는 강철사(9)(9')로 볼록렌즈(5)의 초점에 일치하도록 장설하며, 확대부(1b)의 하단부에는 반호형의 유색유리판(10)을 복착하여서된 것이다.The present invention is to remove the above-mentioned defects and to diffuse the light to a light brighter than the capacity of the light bulb as described in detail below according to the drawings. The filament 3 is formed in the stem tube 2 which is formed in the narrow part 1a and the enlarged part 1b so that the shape of the groove 1 may become narrow upper and wider below. In the mercury-conducting layer 4 formed on the outer circumferential surface of the narrow portion 1a and the upper surface of the enlarged portion 1b, the narrow portion 1a and the enlarged portion 1b which become the lower side of the filament 3 are formed. The intermediate part was formed to be blocked by the convex lens 5 to vacuum the inside of the narrow part 1a. A hollow part 6 was formed below the convex lens 5 and a mercury reflective layer 7 arrived on the outer wall. The reflective reflector 8 is made of thin steel yarns 9 and 9 'so as to coincide with the focus of the convex lens 5, and a half arc-shaped colored glass plate 10 is stacked on the lower end of the enlarged portion 1b. .

이와 같이된 본 고안은 제2도에 표시된 바와 같이 필라멘트(3)의 발광빛과 수은도층(4)에 의하여 협소부(1a)내주면 전체에서 반사되는 반사빛이 볼록렌즈(5)에 조사되고, 볼록렌즈(5)를 굴절투과하면서 반사구(8)의 표면에 집조하게되며, 반사구(8)표면에 조사진 집조광이 다시 확대부(1b)의 내면에 의하여 반사되면서 넓은면적을 밝게 조사(照射)할 수 있게되는 것이다.In the present invention, as shown in FIG. 2, the light emitted from the filament 3 and the reflected light reflected from the entire inner circumferential surface of the narrow portion 1a by the mercury conductive layer 4 are irradiated onto the convex lens 5. When the convex lens 5 is refracted and collected, the light is collected on the surface of the reflector 8, and the reflected light emitted on the surface of the reflector 8 is reflected by the inner surface of the enlarged part 1b, thereby irradiating a large area brightly. It will be able to 照射).

이상과 같이 본 고안은 그로우브(1)내부에 볼록렌즈(5)를 장설하여 필라멘트(3)의 발광빛과 협소부(1a)내면의 반사빛을 볼록렌즈(5)의 초점거리에 맞추어 반사구(8)표면에 조사하도록 되었기 때문에 초점에 모아진 불빛이 매우 밝을 뿐만아니라 이와 같이 밝은빛으로 발광되는 반사구(8)에서 발산되는 빛이 확대부(1b)내면에 의하여 반사시키도록한 종래의 것보다는 그 조명도가 월등히 밝은 장점이 있어 적은용량의 전원으로 주위를 밝게 비추게되는 작용효과를 나타내는 것이다.As described above, the present invention installs the convex lens 5 inside the groove 1 to reflect the light emitted from the filament 3 and the reflected light of the inner surface of the narrow part 1a according to the focal length of the convex lens 5. (8) Since the light focused on the surface is very bright because it is irradiated to the surface, the light emitted from the reflector 8 emitting such bright light is reflected by the inner surface of the enlarged portion 1b rather than the conventional one. Its lighting is very bright, so it shows the effect of brightening the surroundings with a small power supply.
