Abstract
The utility model relates to a wall washing lamp with an air pressure balancing device, in particular to a lamp structure which can show the appearance and the outline of a building or the advertisement arranged on the building by projecting the light on the wall surface of the building. The wall washing lamp with the air pressure balancing device comprises a shell with a cooling fin, two end covers are respectively arranged at two ends of the shell, a transparent face mask together with the shell and the two end covers forms a sealing space, and an aluminum-based circuit board is installed on an inner layer of the shell of cooling fin in the sealing space. The wall washing lamp with the air pressure balancing device is characterized in that the transparent face mask and the shell are sealed by a fastener silicon rubber piece, and an air pressure balancing device is arranged in the middles of the two end covers. The wall washing lamp with the air pressure balancing device has the following functions: due to the air pressure balancing device, the device and a lamp body are connected to balance the pressure difference of the inner part and the outer part of an air lamp body, simultaneously, the air pressure in the lamp body can be protected from being stirred by the outside wind, the increasing of the pressure caused by gas expansion due to the increasing of the temperature in the lamp body can be avoided; and the specific pressing buckle design and a high-temperature-resistant waterproof silicon rubber piece are adopted at the connecting position of the lamp body and the face mask, so that the regular mode that a waterproof silicon rubber piece is glued and extruded is broken, and further the good waterproof effect is achieved.
Description
Technical field
The utility model relates to a kind of wall lamp, particularly a kind ofly can light be projected to building wall, uses the fitting structure that highlights building profile and appearance profile or advertisement on it is set.
Background technology
For the profile and the appearance profile that highlight building or the advertisement on it is set; People can use light fixture usually; Its light is projected to the wall or the advertising department of building, and people are able to clearly in dim environment see building or advertisement by this, and this type of light fixture common name wall lamp.Existing wall lamp, it has housing, lighting and circuit board, and housing is provided with the accommodation space of an opening, and lighting and circuit board are installed in the accommodation space of housing, and through the glass that is installed in the accommodation space opening part it are sealed.Because wall lamp is to belong to outdoor lighting lamp; And the junction of glass and shell has certain slit usually; Or glass cement is beaten at the ring place in oral area, but be inconvenient to keep in repair and waterproof effect unreliable, in use water possibly penetrate into from the slit between glass and the shell in the shell; Make the circuit board short circuit of wall lamp, thereby cause the damage of wall lamp.
In addition, also have the glass cement of use to seal now, but like this because gluing is inhomogeneous, both be not easy sealing, also be not easy demolition and maintenance, sealing effectiveness is bad.
But, even good sealing effect, but owing to seal cavity air pressure owing to reasons such as weather, will inevitably between seal cavity and external environment condition, cause draught head, will cause the light fixture explosion even can explode, influence service life or safety.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of water resistance good, easy for installation, and, can regulate lamp interior air pressure balance high-power wall lamp.
The utility model solves the technical scheme that its technical problem adopted:
Wall lamp with air-pressure balancing device; Comprise shell with fin; The shell two ends are provided with two end cap, and transparent face mask and shell and two end cap form seal cavity, aluminum-based circuit board be installed in the seal cavity on the shell internal layer of fin; It is characterized in that: described transparent face mask and described shell seal through the buckle silica gel strip, are provided with air-pressure balancing device at described two end cap middle part.
As the technical scheme of the further optimization of the utility model, described air-pressure balancing device is made up of cylinder and the piston in cylinder, and piston is provided with air valve, and the cylinder two ends are provided with blow vent.
Technical scheme as the further optimization of the utility model; Cylinder one end of described air-pressure balancing device forms opening; Be used to install piston and get into cylinder, and stop piston to come off, have a blow vent in the middle of the piston plate washer through being fixed in cylinder wall upper piston plate washer.
As the technical scheme of the further optimization of the utility model, described transparent face mask is processed by the PMMA material, and its lighting angle is for being equal to or greater than 20 degree.
As the technical scheme of the further optimization of the utility model, described shell with fin, by the section bar of an extrusion modling of aluminum alloy materials, and surperficial anodic oxidation.
Therefore; The beneficial effect of the utility model is: the utility model adopts a kind of novel air-pressure balancing device that utilizes the mechanical engineering technology design to have novel exhaust system; Through being linked to each other with lamp body, this device fetches balance gas lamp inside and outside pressure reduction; Protect the lamp body air pressure inside not receive outside wind speed disturbance simultaneously, rising and gas expanded in assurance lamp body inside not Yin Wendu, and causes pressure to become big; And unique clinching design and resistant to elevated temperatures water-proof silica-gel bar are adopted in the junction of lamp body and face shield, thus off the beaten track usefulness beat the waterproof of glue and cross the extruding silica gel strip and reach the excellent waterproof effect, reach the IP67 classification of waterproof; Adopt aluminium alloy extruded one-body molded lamp body, have efficient, good heat dispersion, surperficial anodic oxidation, Hpdc aluminium alloy plug, 1.6mm high-quality high thermal conductivity coefficient aluminium base, high thermal conductivity 1.59W.m/K heat conductive silica gel, good heat conductivity; The lens of breaking the normal procedure control lighting angle; The high light face shield of processing by a PMMA; Its main function is the light that secondary distribution LED pipe sends, and light loss is little, and illumination is good; This face shield lighting angle narrow (about 20 degree), effective projection distance farthest are 15-20 rice, let light wash metope as water.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the perspective exploded view of the utility model;
Fig. 2 is the end cap of the utility model and the cutaway view of air-pressure balancing device.
The specific embodiment
With reference to Fig. 1, Fig. 2; The disclosed a kind of wall lamp with air-pressure balancing device of the utility model comprises the shell 1 with fin, and shell 1 two ends are provided with two end cap 6; Transparent face mask 4 forms seal cavity with shell 1 and two end cap 6; Aluminum-based circuit board 3 be installed in the seal cavity on shell 1 internal layer of fin, it is characterized in that: described transparent face mask 4 seals through buckle silica gel strip 2 with described shell 1, is provided with air-pressure balancing device at described two end cap 6 middle parts.The clinching design and the resistant to elevated temperatures water-proof silica-gel bar of this uniqueness adopted in the junction of lamp body and face shield, thus off the beaten track usefulness beat the waterproof of glue and cross the extruding silica gel strip and reach the excellent waterproof effect, reach the IP67 classification of waterproof.
