Generally, out of the lighting devices installed outdoors, a lighting device such as a ground or a road marker installed on the surface of the ground is a device in which most of the main body is embedded in the ground and all parts except the light- And emits an illumination light toward the light source.

Fig. 1 is an exploded perspective view showing a typical outdoor outdoor light. As shown in Fig. 1, an inner tube 2 is housed inside an outer tube 1, and a lamp L is mounted inside the inner tube 2 An illumination light direction adjusting member 6 for converting the direction of the illumination light emitted from the lamp L and a light source direction adjusting member 6 for converting the light from the light source 4 to the light source 4, And a heat ray 7 for preventing the occurrence of heat generation.

The illumination light emitted from the lamp L is projected onto the transparent plate 5 while being reflected by the capsule lens 4 to emit the illumination light to the upper portion of the outer tube 1, do.

However, there is a problem in that the outdoor light according to the prior art always needs to operate the heat line 7 in order to remove condensation of the transparent plate 5.

In addition, when the sealing on the edge of the transparent plate 5 is not firmly sealed, moisture due to rainfall or snowfall may be inflowed.

Korean Patent Registration No. 10-0849734 discloses that the edges of the transparent plates of the shielding member are sealed by the sealing protrusions of the packing and the heat insulating space is formed between the transparent plates, Which prevents condensation or rainwater from flowing into the inside of the apparatus.

2, the main body 54 is embedded in the ground and has an inward flange 50a facing inwardly on the inner circumferential surface of the upper end and a cylindrical inlet port 50a A housing 50 in which a lamp housing 63 is housed in a lower portion of the housing 50 and a power supply base 65 for power supply is built in and a socket 61 are fixed integrally to light the lamp L and collect the illumination light emitted from the lamp L in a state of surrounding the outer circumferential surface of the lamp L and reflect the light, The lamp unit 60 is installed horizontally on the upper end of the housing 50 located at the upper portion of the lamp unit 60 and includes a lamp cap 60 for blocking direct light emitted from the lamp unit 60, Shielding the upper end thereof so as to be capable of transmitting light, and stacking the spaced- A shielding member 70 having a pair of transparent plates 72 with a heat insulating space formed thereon and a packing for sealing the surface of the transparent plate 72 and a sealing member 70 comprising a top plate 82 and a bottom plate 84 And a case (80).

However, in such a conventional underground lamp, the packing case 80 is provided between the upper part of the main body part 54 and the lamp unit 60 so that foreign substances and moisture can be prevented from being inflow from the outside, There is a problem that it is impossible to prevent condensation or icing that occurs inside the main body 54 due to a change in the external environment of the main body 54. [

The prior art has a problem that the air layer included in the space E1 between the main body 54 and the lamp unit 60 and the space E2 between the lamp unit 60 and the shielding member 70 has a temperature difference Condensation occurs, and the generated condensation causes breakage of the lamp unit L, resulting in a problem that the service life of the lamp is lowered.

Korean Registered Patent Publication No. 10-0849734 (title of invention: underground, etc.)
