Abstract
The invention relates to a fireproof LED down lamp. The fireproof LED down lamp comprises a fireproof down lamp body and an LED. An installing hole is formed in the rear end of the fireproof down lamp. A fireproof heat conduction plate provided with the LED covers the installing hole and is in sealed connection with the fireproof down lamp body, and semi-closed space with the front end opened is formed in the fireproof down lamp body. The fireproof heat conduction plate is utilized for being in sealed connection to the rear end of the fireproof down lamp body and covering the installing hole, so that the semi-closed space is formed in the fireproof down lamp body, flames cannot continue to flee upwards after entering the semi-closed space, precious time is saved for user escape, and meanwhile the fireproof performance is effectively improved. Meanwhile, due to the fact that only the fireproof down lamp body and the fireproof heat conduction plate are used, the effect of delayed fire fleeing is achieved; fireproof cotton and other mass accessory structures occupying the space are abandoned, and accordingly, the lamp body structure is simplified, and the producing and manufacturing cost is saved. The fireproof LED down lamp can be applied to fireproof lighting.
Description
Technical field
The present invention relates to lighting field of preventing fires, more particularly to a kind of fire prevention LED down lamp.
Background technology
LED spotlight, Down lamp are generally installation by adhering in the mounting hole that ceiling is opened up, with the development of LED technology, its hotel, meeting room, office of factory, business negotiation place, house, mechanism, school, hospital etc. need energy-conservation and high color rendering index (CRI) building and place in be widely used.In order to extend the escape time of above-mentioned occasion personnel when there is fire, various types of fire prevention Down lamps are developed on the market, its main thought is that lamp body insertion is arranged on fire prevention furred ceiling lamp body is fitted close with fire prevention furred ceiling, and expansible fireproof cotton is pre-installed in lamp body, so as to meet the gap blocked after fire is heated in lamp body.
The content of the invention
In order to overcome above-mentioned technical problem, it is an object of the invention to provide a kind of light fire prevention LED down lamp, fire protecting performance is effectively improved by cleverly structure.
The technical solution adopted in the present invention is：
One kind fire prevention LED down lamp, including fireproof lamp cylinder and LED, the rear end of the fireproof lamp cylinder is provided with mounting hole, and the fire prevention heat-conducting plate covering mounting hole equipped with LED is simultaneously tightly connected with fireproof lamp cylinder (1), makes to form the semi-enclosed space of front opening in fireproof lamp cylinder.With fireproof lamp cylinder as flame isolation layer, the flare above altered is difficult to burn fire proofing material fire prevention heat-conducting plate after the semi-enclosed space for entering fireproof lamp cylinder, improves fire protecting performance, protects the line construction above ceiling, is the time that key is won in user's escape.
Used as the further improvement of above-mentioned technical proposal, the fire prevention heat-conducting plate is sealedly connected on fireproof lamp tube rear end face, and the LED is contained in mounting hole.
Used as the further improvement of above-mentioned technical proposal, the fire prevention heat-conducting plate is located in fireproof lamp cylinder and is tightly connected fireproof lamp cylinder front end face, and the mounting hole is the aperture passed through for the current supply line of LED.
Used as the further improvement of above-mentioned technical proposal, described being tightly connected at the connection hole for the fire prevention heat-conducting plate with fireproof lamp cylinder fills fire proofing.
As the further improvement of above-mentioned technical proposal, the fire proofing is fire-proof mud and/or fire prevention glue, is used to replace the anti-guncotton in conventional art to play sealing fire retardation, greatly reduces the volume of lamp body, the manufacturing cost of lamp is reduced, stronger effect is also functioned to for environmental protection.
Used as the further improvement of above-mentioned technical proposal, the fireproof lamp cylinder is made up of metal fireproof material, such as carbon steel.
Used as the further improvement of above-mentioned technical proposal, the fire prevention heat-conducting plate is made up of metal fireproof material, such as brass, had both kept off fire or had helped LED heat transfer radiatings.Combination is collocated with each other by two kinds of resistant to elevated temperatures melting point properties of material of carbon steel and copper, so as to improve the fire protecting performance of lamp body.
Used as the further improvement of above-mentioned technical proposal, fireproof lamp cylinder is hat shape, and its front end is provided with the shade for inlay card ceiling face, and the rear end face of the shade is provided with flame retardant silica gel.During assembling, flame retardant silica gel is pressed in centre by shade and ceiling, prevents flame from entering ceiling top from side.
As the further improvement of above-mentioned technical proposal, optical lens is provided with the hemi-closure space of the fireproof lamp cylinder, the optical lens is socketed on light cover, and the light cover is located at fireproof lamp cylinder front and is screwed on fireproof lamp cylinder inwall, and optical lens is compressed into fixation using light cover.
As the further improvement of above-mentioned technical proposal, water proof ring is provided between the front end face and light cover of the shade.
The beneficial effects of the invention are as follows：The present invention is sealedly connected in fireproof lamp tube rear end and is covered mounting hole using heat-conducting plate of preventing fires, so that forming a hemi-closure space in fireproof lamp cylinder, flare is altered on cannot continue after hemi-closure space, it is not only that user's escape tries to gain time precious to one, it is also effective to improve fire protecting performance, simultaneously because being to realize postponing the fiery effect that leaps up using only fireproof lamp tin and fire prevention heat-conducting plate, a large amount of accessory structures for taking up room such as anti-guncotton are abandoned, so as to simplify lamp body structure, manufacturing cost has been saved.
