Description

[Technical field] The present invention relates to a heat dissipation structure of a lighting lamp for efficiently dissipating heat emitted from the lighting lamp and preventing light from leaking outside from the heat dissipation hole. is there.

[Background Art] Conventionally, as shown in FIG. 7, there is a lighting lamp 1 which is covered with a lighting cover 2 to illuminate. In this lighting device, heat of the lighting lamp 1 is trapped in the upper part of the lighting cover 2 and the lighting lamp 1 is heated. Of A
The point (the upper part of the lighting cover 2) and the point B (the upper part of the mirror cabinet 5) reach a high temperature of 80 ° to 90 ° C, and the lighting cover 2 made of the acrylic resin sheet and the mirror cabinet made of the polystyrene resin sheet. There is a problem that these are deformed and deteriorated because the temperature exceeds the limit temperature of 5. Therefore, as shown in FIG. 8, it is conceivable to provide a heat dissipation hole 3 on the upper part of the lighting cover 2 to dissipate heat. In this case, the temperature inside the lighting cover 2 decreases, but this heat dissipation hole 3
Therefore, there is a problem that the light of the illumination lamp 1 directly comes out and is reflected on the wall surface 18 and remarkably deteriorates the appearance.

[Object of the Invention] The present invention has been devised in view of the above problems. The object of the present invention is to radiate heat from a heat dissipation hole to lower the temperature in the upper part of the lighting cover and to dissipate the heat dissipation hole. It is an object of the present invention to provide a heat dissipation structure for an illumination lamp in which the light of the illumination lamp is prevented from leaking through the heat dissipation hole even though the heat is dissipated from the inside.

DISCLOSURE OF THE INVENTION According to the present invention, a lower portion of a lighting cover 2 that covers the lighting lamp 1 is opened, and a heat dissipation hole 3 that is directly opened to the outside is provided at an upper end portion of the lighting cover 2. 3, the shield plate 4 for blocking the leakage of the light of the illumination lamp 1 from the heat radiation hole 3 to the outside is lowered from the upper position of the socket 8 to the upper position of the illumination lamp 1 on the socket 8 side. The above-mentioned object of the present invention is achieved by adopting such a configuration. That is, in the present invention, the heat dissipation hole 3 is provided in the upper part of the lighting cover 2 so that the temperature of the upper part inside the lighting cover 2 does not rise, and the light from the illumination lamp 1 is dissipated by the shielding plate 4. The wall 3 is prevented from directly illuminating the outside through the hole 3.

Hereinafter, the present invention will be described in detail with reference to embodiments. The illumination lamp 1 is attached to the mirror cabinet 5. In the embodiment shown in the drawings, the mirror cabinet 5 is constructed by providing a sleeve portion 7 on one side of the mirror attachment portion 6, and a socket 8 is provided on the front surface of the upper portion of the sleeve portion 7 so that the socket 8 is illuminated. The lamp 1 is attached, and the illumination cover 2 is attached to the upper part of the sleeve portion 7 so as to cover the illumination lamp 1. The lighting cover 2 is open at the bottom. Here, the lighting cover 2 is formed of, for example, an acrylic resin sheet, and the mirror cabinet 5 is formed of a polystyrene resin sheet. A mirror 9 is attached to the front surface of the mirror attachment portion 6 of the mirror cabinet 5, and a shelf 10 and the like are provided in the central portion and the lower portion of the sleeve portion 7. A wash basin 11 is provided below the mirror cabinet 5. A heat dissipation hole 3 is formed in the uppermost portion of the lighting cover 2. The shield plate 4 is formed by continuously connecting the shield piece 13 to the upper part of the fixed piece 12 in a diagonally upper front direction. The shield plate 4 is provided above the socket 8 on the upper front surface of the sleeve portion 7.
The fixing piece 12 is fixed by the screw tool 14, the shielding piece 13 of the shielding plate 4 is located between the heat dissipation hole 3 and the illumination lamp 1, and the shielding piece 13 dissipates the light of the illumination lamp 1 for heat dissipation. It is designed so that it cannot be leaked directly to the outside from the hole 3. The above-mentioned illumination lamp 1 is used as the main illumination of the mirror cabinet 5, but the mirror cabinet 5 shown in the drawing is provided with a spot lighting fixture 15 in addition to this. The spot lighting fixture 15 is attached to a decorative pipe 16 attached along the outer peripheral edge of the mirror attachment portion 6 of the mirror cabinet 5. The decoration pipe 16 is further provided with a drier support 17 for detachably mounting the drier, and by supporting the drier on the drier support 17, the wind from the drier is blown to the head. Both hands can be used to dry and condition hair.

[Effect of the Invention] In the present invention, as described above, the lower part of the lighting cover that covers the lighting lamp is opened, and a heat dissipation hole is provided at the upper end of the lighting cover, and the space between the lighting lamp and the heat dissipation hole is provided. In the above, since a shielding plate that is inclined upward is arranged to block the light of the illumination lamp from leaking outside from the heat dissipation hole, when the illumination lamp generates heat, the air near the illumination lamp is warmed. It rises and radiates heat from the heat dissipation hole at the upper end of the lighting cover, but in this case, new air enters the lighting cover while rising from the opening at the bottom of the lighting cover and rises inside the lighting cover to turn on the lighting lamp. While cooling, it rises while being guided by the sloping shield plate above the lighting lamp and radiates heat from the heat dissipation hole, which efficiently cools the lighting lamp and externally collects heat at the upper end of the lighting cover. What Heat can be efficiently dissipated, and because the shield plate is installed obliquely upward from the position above the socket to the position above the illumination lamp so that the socket side becomes lower, hot air stays above the socket side. In addition, when the air from below is guided by the inclined shield plate and flows upward, new external air flows straight to the socket side from the opening at the bottom of the lighting cover to cool the socket part and Guided by the shield plate, it passes above the lighting lamp and is exhausted to the outside from the heat dissipation hole at the upper end of the lighting cover.As a result, the hot air of the lamp does not flow to the socket side and the socket side It is not affected by heat, and it is possible to dissipate heat from the lighting lamp in this way so that the heat of the lighting lamp does not stay inside the lighting cover. In addition, the shielding plate can block the light from the illumination lamp so that it does not go out directly from the heat dissipation hole, and as a result, the light leaked from the heat dissipation hole does not illuminate the wall surface and deteriorate the appearance. Is something
In this way, the single shielding plate has both the function of preventing the heat of the lamp from staying inside and the function of preventing the light from leaking from the heat dissipation hole. It can be simplified.
