Abstract
The utility model relates to an explosion-proof lamp which comprises a lamp body, a heat absorption disc, an illuminating part, a lamp panel, a lamp shade and a ballast, wherein, the lamp body and the lamp panel are movably connected, the heat absorption disc is arranged in the lamp body, an inner cavity where the lamp body and the lamp panel are communicated are divided into an upper chamber and a lower chamber, the illuminating part is arranged in a lower cavity chamber at the lower end of the heat absorption disc, the ballast is arranged in an upper cavity chamber at the upper end of the heat absorption disc, the lamp shade is fixed at the lower end of the lamp panel, and a heat insulating plate made of thermal insulating material is arranged between the ballast and the heat absorption disc. The heat generated by the illuminating part is absorbed by the heat absorption disc and is guided out through the adjacent radiating fins, and the redundant upwelling heat is obstructed in the cavity between the heat insulating plate and the heat absorption disc so as to achieve the purpose for protecting the ballast and other parts. Compared with the prior art, the utility model has the advantages that not only the heat radiation effect is good, but also the heat can be isolated for protecting other parts, therefore the service life of the product is prolonged.
Description
Technical field
The utility model relates to a kind of explosion-proof lamp.
Background technology
Existing explosion-proof lamp is made up of lamp body, absorbing heat disk, illuminating part, lamp panel, lampshade, ballast parts such as (or radio-frequency generators), lamp body and lamp panel flexibly connect, absorbing heat disk is arranged in the lamp body, the inner chamber of lamp body and lamp panel connection is separated into upper and lower two chambers, illuminating part is arranged in the chamber of absorbing heat disk lower end, ballast is arranged in the chamber of absorbing heat disk upper end, and lampshade is fixed on the lamp panel lower end.In explosion-proof lamp work, illuminating part can produce a large amount of heats, owing to be airtight between lampshade and the lamp panel, can't dispel the heat, these heats can only up move, though absorbing heat disk can adsorb certain heat, because the contact area of it and lamp body is limited, can't very fast heat radiation, a large amount of heats still can see through absorbing heat disk, reaches the chamber at ballast place, and the time one is long, cause ballast life to descend, influence the operate as normal of explosion-proof lamp.
Summary of the invention
The purpose of this utility model is at deficiency of the prior art, provides a kind of and dispels the heat better, explosion-proof lamp that again can be heat insulation.
For achieving the above object, the utility model adopts a kind of explosion-proof lamp, comprise lamp body, absorbing heat disk, illuminating part, lamp panel, lampshade, ballast, lamp body and lamp panel flexibly connect, and absorbing heat disk is arranged in the lamp body, and the inner chamber that lamp body and lamp panel are communicated with is separated into upper and lower two chambers, illuminating part is arranged on the bottom chamber of absorbing heat disk lower end, ballast is arranged in the upper chamber of absorbing heat disk upper end, and lampshade is fixed on the lamp panel lower end, is provided with the thermal insulation board of being made by heat-barrier material between ballast and absorbing heat disk.
The utility model further is set to thermal insulation board to be made up of upper and lower two layers of plastic, is provided with thermal insulation layer in the cavity between upper and lower two layers of plastic.
In order to increase area of dissipation, the utility model further is set to the corresponding fin that is provided with in position of corresponding absorbing heat disk on the lamp body outer wall.
The utility model further is set to lamp body outer wall upper edge and is radially distributed with a plurality of fin.
The utility model further is set to both sides, thermal insulation board lower surface again fixed support is installed, and the support bracket fastened other end is between the installation screw of installing hole on the lamp body inwall and absorbing heat disk both sides, and the three is fixedly connected.
The utility model is provided with the thermal insulation board of being made by heat-barrier material again between ballast and absorbing heat disk on the structure of original absorbing heat disk, simultaneously the corresponding fin that is provided with in the position of corresponding absorbing heat disk on the lamp body outer wall.The heat that illuminating part produces, except that absorbed by absorbing heat disk and relies on derive with its close neighbour's fin, the heat that gushes on unnecessary is reached the purpose of protecting parts such as ballast by in the cavity of thermal insulation board obstruct between thermal insulation board and absorbing heat disk.Compare with prior art, the utility model not only radiating effect is better, and can completely cut off heat protection miscellaneous part, has prolonged the service life of product.
