5 : 자외선차단막 6 : 형광채충5: sunscreen 6: fluorescent insect repellent

본 고안은 전구형 형광등에 관한 것으로써, 특히 외구의 내부표면에 형광체층과 적외선방지층을 형성하여 발광면적을 최대화하는 고효율 전구형 형광등에 관한 것이다.The present invention relates to a bulb-type fluorescent lamp, and more particularly to a high-efficiency bulb-type fluorescent lamp to maximize the emission area by forming a phosphor layer and an infrared ray prevention layer on the inner surface of the outer sphere.

일반적으로 전구형 형광등은 제 1 도에 도시한 바와 같이, 캡(1)과 베이스(2) 및 외구(3) 그리고 발광관(4)로 구성되어지므로 소형화 또는 콤팩트화 할 수 있음과 아울러 전구 소켓에 직접 끼워 사용할 수 있는 간편성등이 있다.In general, the bulb-type fluorescent lamp is composed of a cap (1), a base (2) and the outer opening (3) and the light emitting tube (4), as shown in Figure 1 can be miniaturized or compact as well as bulb socket There is simplicity that can be used directly by plugging in.

그러나 전구형 형광등은 발광관(4)내의 수은원자가 전극에서 방출되는 전자에 의해 여기되어 자외선이 발생되도록 되어 있으나, 외구(3)을 통과할 때 투과손실이 발생하여 환형 또는 직관형 형광등에 비하여 그 효율이 낮은 결점이 있다.However, the bulb-type fluorescent lamp is generated by the mercury atoms in the light emitting tube 4 are excited by the electrons emitted from the electrode to generate ultraviolet light, but the transmission loss occurs when passing through the outer bulb (3), compared to the cyclic or straight fluorescent lamps. There is a drawback of low efficiency.

이러한 결점은 상기한 바와같이 외구를 투과할 때 손실이 크게 발생되나, 발광관의 벌브두께가 보편적으로 두껍고, 그 내면에 적외선 차단막이 코오팅되어 지므로해서 발생되는 광의 손실도 크게 나타난다.Such defects are largely lost when penetrating the outer opening as described above, but the bulb thickness of the light emitting tube is generally thick, and the loss of light generated by coating the infrared blocking film on the inner surface is also large.

본 고안은 상기한 제반 문제점을 감안하여 안출한 것으로써 발광관의 두께를 가급적 얇게하여 발광관내의 형광체를 여기시키고 난 여분의 자외선이 쉽게 방사되도록하고, 형광등 내면에 존재하던 자외선 차단막을 배제하여 자외선 투과를 더욱 용이하게 하며, 외구내면에 반투명의 형광체를 코오팅하여 발광효율을 극대화시킬수 있는 고효율의 전구형 형광등을 제공함에 그 목적이 있다.The present invention has been made in view of the above-mentioned problems, and the thickness of the light emitting tube is made as thin as possible to excite the phosphor in the light emitting tube so that the extra ultraviolet light is easily radiated, and the ultraviolet blocking film existing on the inner surface of the fluorescent lamp is excluded. The purpose of the present invention is to provide a high-efficiency bulb-type fluorescent lamp that can facilitate the transmission and maximize the luminous efficiency by coating a translucent phosphor on the outer surface.

이하 본 고안의 구성을 첨부된 도면에 의하여 좀 더 상세히 기술하면 다음과 같다.Hereinafter, the configuration of the present invention will be described in more detail with reference to the accompanying drawings.

제 2 도에 도시한 바와같이, 캡(1)과 베이스(2) 및 외구(3) 그리고 발광관(4)로 형성되는 통상의 전구형 형광등에 있어서, 전기한 외구(3)의 내측에 자외선 차단막(5)를 코오팅하여 그위에 형광체층(6)을 코오팅하고, 발광관(4)는 진공유지 가능한 최소한의 두께로 하여 그 내면에 형광체층(6')를 코오팅하는 구성이다.As shown in FIG. 2, in a conventional bulb-type fluorescent lamp formed of a cap 1, a base 2, an outer bulb 3, and a light emitting tube 4, ultraviolet rays are formed inside the outer bulb 3 as described above. The barrier film 5 is coated to coat the phosphor layer 6 thereon, and the light emitting tube 4 is coated with the phosphor layer 6 'on its inner surface to a minimum thickness that can be maintained in vacuum.

도면중 미설명부호 7은 증기상태의 수은 원자이다.In the figure, reference numeral 7 denotes a mercury atom in the vapor state.

이와같이 구성되는 본 고안은 발광관(4)의 양단에 설치된 전극(도시생략)에서 전자가 방출되므로써 발광관(4)의 내부에 증기상태로 존재하는 수은원자(7)이 전자에 의해 여기되고 다시 천아상태로 복귀할때 자외선이 방출된다.According to the present invention, the mercury atom 7 existing in the vapor state inside the light emitting tube 4 is excited by electrons by electrons emitted from electrodes (not shown) provided at both ends of the light emitting tube 4. Ultraviolet rays are emitted when returning to the natural state.

이 자외선은 발광관(4)의 내벽에 코오팅된 형광체층(6')를 여기시켜 1차 발광상태에 이르게 되는데, 발광관(4)의 두께가 얇음으로해서, 발광관(4)내의 형광체층(6')를 여기시키고 난 여분의 자외선이 쉽게 발광관(4) 밖으로 방사된다.The ultraviolet light excites the phosphor layer 6 'coated on the inner wall of the light emitting tube 4 to reach the primary light emitting state. The light emitting tube 4 is thin so that the phosphor in the light emitting tube 4 is thin. The extra ultraviolet radiation that excites the layer 6 'is easily emitted out of the light tube 4.

이와같이 방사된 자외선은 외구(3)의 내면에 반투명으로 코오팅된 형광체층(6)을 여기시켜 2차 발광상태에 이르게 된다.The emitted ultraviolet rays excite the phosphor layer 6 coated with translucent coating on the inner surface of the outer sphere 3 to reach the secondary emission state.

이때 외구(3)에 코오팅된 형광체층(6)은 발광관(4)에서 방사된 가시광이 차단되지 않고 방출되도록 가능한 얇게 코오팅 되어지는 것이 바람직하다.At this time, the phosphor layer 6 coated on the outer sphere 3 is preferably coated as thin as possible so that visible light emitted from the light emitting tube 4 is not blocked.

적외선이 외구(3)을 통하여 외부로 방사되면 인체에 해로우므로 자외선 차단막(5)를 외구(3) 내측에 코오팅하여 방지한다.When infrared rays are radiated to the outside through the outer sphere (3) is harmful to the human body to prevent the UV blocking film (5) by coating the inside of the outer sphere (3).

이상과 같이 본 고안의 전구형 형광등은 발광관(4)의 두께를 얇게함과 동시에 자외선 차단막을 배제하여 자외선 투과를 용이하게하고, 발광관(4)와 외구(3)에서 2차 발광을 하게하여 발광면적을 최대로하고 자외선의 이용율을 높여 형광등의 효율을 한층 향상시킬수 있는 고안인 것이다.As described above, the bulb-type fluorescent lamp of the present invention thins the thickness of the light emitting tube 4 and at the same time excludes an ultraviolet ray blocking film to facilitate ultraviolet transmission, and allows the second light emitting tube to emit light from the light emitting tube 4 and the outer opening 3. By maximizing the light emitting area and increasing the utilization rate of ultraviolet rays, it is designed to further improve the efficiency of fluorescent lamps.
