Definitions

  • the embodiment of the present invention relates to a flat lamp device having, for example, a GX53 type base.
  • the translucent cover 6 is formed in a substantially donut shape or ring shape by a transparent resin such as polycarbonate or acrylic.
  • the translucent cover 6 is placed on the upper part of the base 2, the outer peripheral edge of the translucent cover 6 is on the upper surface of the side wall 2 c of the base 2, and the inner peripheral edge is on the side wall of the base 2 above the central convex part 2 a.
  • Each is fixed.
  • the translucent cover 6 has covered the light source 4, it is located in the same plane as the protrusion end surface of the center convex part 2a, and is following the protrusion end surface.
  • the surface of the translucent cover 6 is formed with a texture to make it difficult to see wiring and the like through the inside.
  • the central convex portion 2a of the substrate 2 has a truncated cone shape, but is not particularly limited to this shape, and may be a cylindrical shape or a pyramid shape, and may not be a rotationally symmetric shape. Needless to say.
  • the central convex portion 2 a of the main body 10 is constituted by the base 3, not the base material 2. That is, the base 3 includes a ceiling wall 14 having a central convex portion 2a formed of a synthetic resin.
  • the ceiling wall 14 is disposed in the storage recess 12, and the central convex portion 2 a is inserted through the central opening of the base material 2 and protrudes forward.
  • the translucent cover 6 includes a protruding portion 6a protruding from the inner surface, a light intake portion 6b, and a side wall portion 6c, and a cross section of the protruding portion 6a.
  • the shape is the same as that of the third embodiment.
  • the protrusions 6a have a rotationally symmetric shape with the individual light sources 4 as the central axes, whereas in the fifth embodiment, the protrusions 6a have a central axis of the flat lamp device. On the other hand, it is formed in a rotationally symmetric shape.
  • FIG. 6A is a cross-sectional view showing a flat lamp device 1 according to a sixth embodiment.
  • the basic configuration of the lamp device 1 is the same as that of the fourth embodiment, and the configuration of the translucent cover 6 is partially different.
  • the taper angle of the outer peripheral surface of the side wall 6c is different from that of the fourth embodiment, and the opening angle between the inner peripheral surface and the outer peripheral surface is reduced.
  • the translucent cover 6 configured as described above, light emitted from the light source 4 in a relatively lateral direction is not reflected by the outer peripheral surface of the side wall portion 6c, but is bent upward and emitted.
  • FIG. 7C shows the light distribution of the flat lamp device 1.
  • the translucent cover 6 irradiates a considerable amount of light from the side surface to the back side of the lamp device, so that a flat lamp device 1 with a wide light distribution can be realized.
