The present invention relates to a lamp used to hang on the ceiling, in particular to reduce the heat transfer rate of emission from the lamp to prevent overheating due to the rise in the surface temperature of the lamp cover.

I. The technical problem the invention is trying to solve.

Normally, a lamp having a high halogen lamp having a high heat emission rate is used as a cover of a lamp, which is made of aluminum, which is heat resistant and can be manufactured at a light weight.

However, in this case, not only is the thickness of the lamp cover due to light weight, but also the heat emitted from the lamp is transferred as it is due to the high heat transfer rate of aluminum, so that the surface temperature of the lamp shade rises rapidly in a short time, resulting in overheating. There is a problem that causes a risk of burns and a change in form.

All. The gist of the solution of the invention.

Therefore, the present invention is to form a double layer structure consisting of the interior and the exterior of the lamp cover to form an air layer for the air-cooling effect between the surfaces to reduce the heat transfer rate to the surface of the cover to prevent overheating.

Description

A lighting preventing an illuminator from being overheated}

The present invention relates to a lamp having an overheat prevention means, and more particularly to prevent overheating caused by excessive temperature rise lost in the process of the heat emitted from the lamp reaches the surface of the lamp cover.

Conventional lamps are made of light and easy to produce acrylic as a cover material for lamps installed around the lamp.However, when a halogen lamp with a high heat dissipation rate is mounted, a metal material with less deformation due to the heat emitted is used. In particular, in consideration of the installation characteristics to be suspended in the ceiling, etc., the use of aluminum as a material capable of producing a hard metal.

However, in this case, not only is the thickness of the lamp shade according to the manufacture of light weight, but also the heat emitted from the lamp is transferred as it is due to the high heat transfer property of aluminum, and the surface temperature of the lamp cover rises rapidly in a short time, resulting in overheating. There is a problem that the risk of wearing is followed, and also because of the change in form due to the heat deformation of the lamp cover that appears when overheating, there is a problem that results in damage to the appearance.

Therefore, the present invention has been made to solve the above-mentioned conventional problems, the object of the present invention is to reduce the heat transfer rate reached from the lamp to the surface of the lamp cover to prevent overheating.

To this end, the present invention is made of a cover of the inner light and the inner body to form an air layer between the inner body and the outer body so that the heat is gradually lost in the process of passing through the inner body and the air layer.

Hereinafter, with reference to the accompanying drawings will be described in detail the most preferred embodiment of the present invention. First, in describing the drawings, the same reference numerals are used to refer to the same elements even though they are shown in different drawings.

As shown in FIG. 1, the present invention is a conventional luminaire, which is a double body structure including a cover of a lamp such as an inner body 10 and an outer body 20, and an air layer 30 between the inner body 10 and the outer body 20. ) To prevent overheating of the lamp cover.

At this time, the inner body 10 and the outer body 20 of the cover are bent so as to correspond to each other to each other bent surface 11, 21 by using a coupling member 40 such as screws to bend the surface 11 The air layer 30 can be naturally formed by the 21, and the larger the thickness of the air layer 30 is, the lower the heat transfer rate to the outer body 20 is, but the proper thickness is formed to prevent excessive overheating of the inner body 10. It is preferable to make it.

In addition, by forming another bent surface (11a) on the upper end of the inner body 10 so that the edge portion of the bent surface (11a) abuts the inner surface center of the outer body 20, the outer body due to the increase in weight due to the inner body 10 formed ( The effect of reinforcement to prevent the shape change of 20) is intended.

In this case, the air layer 30 is separated into upper and lower parts. In particular, the air layer 30a formed on the upper part has an air layer because the heat transfer rate generated from the lamp 50 is high due to the proximity of the lamp 50 to be mounted. The outlet 22 is formed in the outer body 20 in consideration of the increase in volume due to the temperature increase of 30a).

Of course, even when the air layer 3 is not separated, it is possible to form an outlet 22 to cope with an increase in volume due to the internal temperature rise.

In addition, a protective net 60 is further formed on the edge portion between the inner body 10 and the outer body 20 of the cover to prevent access to the lamp 50 housed inside the lampshade, thereby preventing potential risks in advance. It is supposed to be.

Therefore, the luminaire of the present invention configured as described above has a heat loss and an air layer at the time of passing through the solid due to the inner body 1 while the heat generated from the lamp 5 passes through the inner body of the cover 1 and the air layer 3. Due to the heat loss effect of the air cooling method due to (3), the heat transfer rate until reaching the outer body 1 is greatly reduced, thereby lowering the surface temperature of the cover outer body 1 to sufficiently prevent overheating.

As described above, the illumination lamp of the present invention can prevent the risk of burns due to the overheating effect of the surface temperature, as well as prevent the deformation of the lamp shade due to overheating, thereby preserving the appearance.
