Technical Field

The invention relates to the technical field of heat dissipation, in particular to a simple shading exhaust device and a stage lamp with the same.

Background

For guaranteeing the normal life of stage lamp light source, need maintain a relatively more stable environment, consequently often arrange the light source in a relatively inclosed microenvironment, the outside is provided with in fan unit blows the light source chamber outside cold wind drum into the light source chamber confined space, light source chamber confined space sets up an air outlet, the steam in the light source intracavity flows through outside this air outlet discharge lamp body, because there is the highlight in the light source intracavity, influence lamps and lanterns effect for avoiding light to spill, need set up the structure of being in the light at the air outlet, the structure of being in the light both does benefit to the exhaust, can effectively be in the light again, and still can conveniently dismantle and change the light source. The traditional scheme is that the louver radiator is arranged on the air outlet, the structure and the production and processing technology of the radiator are usually complex, the frame and the blade surface of the louver radiator are required to be produced independently and then assembled, and the cost is high.

Disclosure of Invention

In order to overcome at least one defect in the prior art, the invention provides the simple shading and exhausting device which is simple in structure, simple in production and processing technology, low in cost and good in shading and ventilating effects.

In order to solve the technical problems, the invention adopts the technical scheme that: the utility model provides a simple and easy shading exhaust apparatus, includes relative setting and the ventilating board and the light screen of mutual interval, be provided with the vent on the ventilating board, the vent by the die-cut formation of ventilating board, the light screen is in vertical projection on the ventilating board covers the vent.

According to the simple shading exhaust device, the vertical projection of the light screen on the ventilation board covers the ventilation opening on the ventilation board, so that the light screen can prevent light from leaking out of the ventilation opening, airflow can flow out of the gap between the light screen and the ventilation board, the light screen and the ventilation board are common flat plates, special design is not needed, direct punching can be achieved, the ventilation opening formed in the ventilation board is also formed in a punching mode, the ventilation opening can be machined simultaneously when the ventilation board is manufactured, compared with the manufacturing of a louver, the simple shading exhaust device is simpler to manufacture, a better shading ventilation effect can be achieved only by two common flat plates fixed to each other, and assembly time and production cost are effectively reduced.

Further, one side of the ventilation plate, which is close to the light shielding plate, is provided with a coaming plate arranged around the light shielding plate. The setting of bounding wall can avoid the hot gas flow certainly gap between ventilating board and the sealed chamber flows out, is installing like this during simple and easy shading exhaust apparatus, even there is arch, unevenness when ventilating board or sealed chamber make, perhaps because the vibrations during the use lead to both can't closely laminate, the ventilating board shifts up or moves down, the bounding wall can all play certain wind-guiding passageway's effect, leads out outside the casing smoothly with the hot gas flow.

Further, the height of the coaming is less than the minimum distance between the base plate and the light shield. The hot air flow is facilitated to enter between the shading plate and the ventilating plate.

Further, the size of the ring shape enclosed by the enclosing plates is larger than that of the enclosing plates. The flow of hot air flow between the shading plate and the ventilation plate is facilitated, and therefore the hot air flow is guided out of the shell.

Further, the pull rod and the shading plate are located on the same side of the ventilating plate. The space occupation of the simple shading exhaust device is smaller, and the installation is more convenient.

Furthermore, the ventilating plate comprises a ventilating plate and a fixed plate which are attached to each other, a first exhaust port is arranged on the ventilating plate, a third exhaust port corresponding to the first exhaust port is arranged on the fixed plate, the base plate is located on one side, close to the light shielding plate, of the ventilating plate, and the pull rod is fixedly connected with the fixed plate. Because the ventilation plate can be provided with the screw hole to fix the ventilation plate, the fixing plate is independently arranged to fix the pull rod, so that the phenomenon that the ventilation plate falls down due to the fact that the fixing screw of the pull rod is mistakenly detached when the ventilation plate is detached can be avoided.

Further, the first exhaust port comprises a plurality of parallel strip-shaped holes. The opening of the first exhaust port is prevented from being too large, so that sundries or rainwater can enter from the opening.

Furthermore, a support column is arranged between the light shielding plate and the ventilating plate, and a screw penetrates through the light shielding plate and the support column and is connected with the ventilating plate. The support column can ensure the distance between the shading plate and the ventilation plate.

The invention also provides a stage lamp which comprises a light source cavity and any one of the simple shading exhaust devices, wherein the light source cavity is provided with an air outlet, the ventilation plate is covered on the air outlet, and the shading plate is positioned in the light source cavity.

The light screen is located the light source intracavity uses earlier the light screen shading, and the rethread lid is established on the air outlet the ventilating board ventilates, and the light that can be better avoids leaks, does not influence simultaneously and ventilates.

Further, the ventilating board is close to light screen one side has the encircleing around the light screen sets up, the lateral wall of bounding wall with the light source chamber forms the annular lateral wall of air outlet is laminated mutually. The arrangement of the coaming can prevent hot air from flowing out of a gap between the ventilating plate and the light source cavity and entering the shell of the stage lamp to cause the rise of the environmental temperature in the shell of the stage lamp; and the lateral wall of bounding wall with the light source chamber forms the annular side wall of air outlet is laminated mutually, is installing like this during simple and easy shading exhaust apparatus, even the ventilating board perhaps there is arch, unevenness when the light source chamber is made, perhaps because the vibrations during the use lead to both can't closely laminate, the ventilating board shifts up or moves down, the bounding wall can all play certain wind-guiding passageway's effect, comes out the water conservancy diversion that does not reveal with the hot gas flow in the light source intracavity, discharges outside the casing of stage lamp.
