Description

Technical Field

[0001] This invention relates to the field of stage lighting technology, and more particularly to an anti-condensation structure for a stage light source device. Background Technology

[0002] As attached Figure 1 As shown, the existing stage light source device includes a light panel 1', LED beads, and a lens holder 2'. A heat sink 3' is also installed on the light source device. The heat conduction plate 4' of the heat sink 3' can dissipate heat from the light panel 1' during operation to prevent the light panel 1' from burning out due to excessive temperature. Specifically, the light panel 1' is exposed inside the lamp body and is easily in contact with the hot air inside the cavity. When the light panel 1' stops working, the heat sink 3' and the light panel 1' are still exchanging heat. At this time, the temperature of the light panel 1' drops rapidly, resulting in a large temperature difference between the light panel 1' and the hot air inside the lamp body. Therefore, condensation is likely to occur on the light panel 1', producing water droplets. These water droplets can easily cause the light panel 1' to burn out due to short circuits, or even cause dangerous incidents such as fires. Summary of the Invention

A lens holder, covering the LED beads, is fixedly connected to the upper surface of the light panel. A heat-conducting plate is attached to the lower surface of the light panel. A first connecting portion extending outward is fixedly connected to the periphery of the lens holder. A second connecting portion, surrounding the light panel, is fixedly connected to the lower end of the first connecting portion. The first connecting portion is sealed to the heat-conducting plate via the second connecting portion, forming a sealed space within which the light panel is situated.

[0006] Further defined, the anti-condensation structure includes a base plate, the base plate having a hollow cavity through it, the hollow cavity having an upper opening and a lower opening that communicate with each other, the second connecting part including a wall portion of the hollow cavity, one end of the wall portion being sealed to the first connecting part to close the upper opening, and the other end of the wall portion being sealed to the heat-conducting plate to close the lower opening.

[0007] Further limited, the second connecting part includes an upper annular flange part arranged around the upper opening edge, and an end surface of the first connecting part is provided with a groove, and the first connecting part is matched with the upper annular flange part through the groove.

[0008] Further limited, an upper end surface of the upper annular flange part is provided with a first waterproof groove for containing a first sealing strip, and the first waterproof groove is in sealing contact with the groove through the first sealing strip.

[0009] Further limited, the second connecting part includes a lower annular flange part arranged around the lower opening edge, and an end surface of the lower annular flange part is provided with a second waterproof groove for containing a second sealing strip, and the second waterproof groove is in sealing contact with the heat conduction plate through the second sealing strip.

[0010] Further limited, a bottom end of the lens seat is provided with a third waterproof groove for containing a third sealing strip, and the third waterproof groove and the lamp plate are in sealing contact through the third sealing strip.

[0027] The sealed space 10 can effectively isolate the inner cavity of the lamp body from the air, avoiding condensation of the lamp plate 1 and the inner cavity air due to a large temperature difference, and further, the sealed space 10 is as small as possible to reduce the air capacity in the sealed space 10, so that the total amount of water vapor is also small under the condition that the moisture content is unchanged, thereby avoiding the continuous condensation of water vapor on the lamp plate 1.

[0028] Of course, we can also selectively in sealed space 10 into high temperature does not release water vapor desiccant; or filled with inert gas to exclude the original water vapor. In addition, the inert gas (such as helium, neon, argon, krypton, xenon) advantage is that the volume changes less when the temperature changes, to avoid the sealed space 10 pressure changes caused by the leakage of the seal. The above measures can further ensure the dry environment of the sealed space 10, to the greatest extent to prevent the condensation phenomenon of the lamp panel 1.
