The diffused lens part 13 formed concave for diffusing light toward the image is formed with a lens cap 12 formed to be curved on the upper side.

상기 확산렌즈부(13)는 LED(5)에서 조사되는 빛의 확산을 위하여 중심에서 외곽으로 갈수록 두께가 점진적으로 얇아지도록 형성된다.The diffusion lens unit 13 is formed to gradually become thinner from the center to the outside in order to diffuse the light emitted from the LED 5.

한편, 도 2 (b)는 상기 확산렌즈부(13)의 중심부 저면에 볼록부(14)를 하향 돌출시켜 LED(5)에서 조사되는 빛의 중심부 조도가 좀더 향상될 수 있도록 한 것이고, 도 2 (c)는 확산렌즈부(13)의 저면부를 평탄하게 형성한 것으로서, 제 1 실시예와 동일한 효과를 기대할 수 있게된다.On the other hand, Figure 2 (b) is to protrude the convex portion 14 to the bottom surface of the central portion of the diffusion lens portion 13 to improve the central illuminance of the light irradiated from the LED (5), Figure 2 (c) is a flat bottom portion of the diffusion lens portion 13, and the same effect as in the first embodiment can be expected.
