Description

stage lamp system with electrode heat protection function

Technical Field

The utility model relates to a stage lamp field especially relates to a take stage lamp system of hot protect function of electrode.

Background art;

As shown in fig. 1, when the stage lamp is used, the filter 100 reflects the light that is not passed back to the light source according to the principle of light reflection, because the original light is converged, the reflected light is converged on the end electrode 300 of the bulb wick 200 again, so that the electrode is ablated strongly, the bulb electrode is overheated and broken, the light source is damaged, and the lamp cannot work normally. The usual solution is to place a blower in close proximity to cool the electrodes. However, the effect is not perfect, after all the surface area of the electrodes is too small and the wind speed and the wind volume are limited.

Another approach is to add light reflecting or absorbing means, such as high temperature resistant metal discs, optical reflectors as disclosed in CN208487446U, which are positioned between the green sheet and the bulb by means of corresponding fixtures, which are typically attached to the lamp cup and cannot move. On one hand, the fixing piece can cross the light-emitting direction of the bulb to block light, and on the other hand, after the light source is properly adjusted in the lamp cup, the metal disc and the reflector which cannot move cannot accurately shield light energy and light reflected to the end part of the lamp wick.

Detailed Description

As shown in fig. 2 and fig. 3, the stage lamp system with the electrode thermal protection function includes a bulb 1, a wick 2, a shielding cover 3 and a filter 4 arranged from back to front along an axis of an optical axis, the wick 2 is a columnar glass wick, an electrode 5 is connected to a front end of the wick 2, and the shielding cover 3 blocks light energy and light rays reflected from the filter 4 to a front end of the wick 2. Those constructions described above are prior art and the principles thereof will be understood by those skilled in the art with reference to CN208487446U, embodiments will not be described in detail,

The embodiment of the hiding cover 3 is provided with a connector 6 extending toward the mantle 2, and the hiding cover 3 is positioned on the mantle 2 by the connector 6. From this, it is the linkage to shelter from lid 3 and wick 2, and the illumination in-process is no matter how the adjustment of wick 2 in the light cup, the translation rotates, shelters from lid 3 and wick 2 tip, also promptly and the electrode 5 between the distance all can not change, only need before the assembly to shelter from the distance setting that lid 3 and wick 2 tip be close to and the distance that is close to comparatively reasonable, shelter from lid 3 homoenergetic separation from light filter 4 reflection to electrode 5's light and light energy.

The cover 3 is preferably arranged so that its cross-sectional area in the direction perpendicular to the optical axis is larger than the cross-sectional area of the front end of the wick 2.

The stage lamp is also provided with an active radiator, such as an internal radiator fan, and because the surface area of the shielding cover 3 is much larger than that of the electrode 5 (filament), after the shielding cover 3 generates heat, the radiator fan can easily cool the shielding cover 3, so that the electrode 5 is prevented from being damaged.

Further preferably, the connecting piece 6 is sleeved on the outer wall of the lamp wick 2, and the inner wall of the connecting piece 6 is attached to the outer wall of the lamp wick 2. The sleeving manner can limit the radial freedom degree of the connecting piece 6 and the shielding cover 3, and the connecting piece 6 can be sleeved at different axial positions of the lamp wick 2 according to requirements, so that the shielding cover 3 can not contact the electrode 5, but is close to the electrode 5 as much as possible.

In one embodiment, the connecting member 6 is a thin metal material, which has elasticity and is elastically sleeved on the outer wall of the wick 2, and the connecting member is axially positioned by friction between the two.

In another embodiment, the connecting element 6 is made of a ceramic material, which, because of its lack of elasticity, requires the use of cement at high temperature to bond the connecting element 6 to the wick 2 for axial positioning.

In another embodiment, the connecting member 6 is made of a thin metal material, and has elasticity so as to be sleeved on the outer wall of the wick 2 by the elasticity, so that the friction between the connecting member and the wick is utilized to perform axial positioning, and the connecting member and the wick are bonded and fixed by high-temperature mud, thereby ensuring the firmness and reliability of the connecting member and the wick.

The shielding cover 3 is made of high temperature resistant material, can be integrally formed by the same metal and ceramic as the connecting piece 6, and can also be assembled by different materials.

Further preferably, the part of the connecting piece 6, which is sleeved on the outer wall of the lampwick 2, is a hoop 61, and the hoop 61 is specifically a vertical groove formed in the material of the circular ring, so that the circular ring forms two embracing arms, one ends of the two embracing arms are connected, and the other ends of the two embracing arms are separated. The anchor ear structure is easy to be sleeved in the lamp wick 2, in particular to the anchor ear structure of the elastic metal sheet.

Further preferably, the connecting piece 62 includes a connecting piece 62 for integrally connecting the cover 3 and the hoop 61, in addition to the hoop 61 for receiving the wick 2. The connecting piece 62 is eccentric with respect to the axis of the optical axis and is offset from the electrode 5, but the connecting piece 62 is closer to the outer wall of the wick 2 to reduce the influence on the emergent light of the bulb 1.

Further preferably, the shielding cover 3 is made of a light-tight material, preferably a high-temperature-resistant metal material or a ceramic material.

In one embodiment, the shielding cover 3 is coated with a highly reflective light substance as a light-reflecting layer, such as a surface chrome-plated layer, on the surface facing the optical filter 4, reflecting the highly reflective light from the optical filter.

In another embodiment, the cover 3 is coated with a highly light-absorbing substance as an absorbing layer on the surface facing the filter 4, for example, with a frosted black surface, which absorbs the highly reflected light from the filter 4.

In other embodiments, the cover 3 is coated with both a light-reflecting layer and an absorbing layer on the surface facing the filter 4.

The above description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention.
