The specific embodiment
Fig. 1 represents lamp protective case of the present invention.Protective case 1 integral body is drum, is formed for the opening 2 (2a, 2b) of the insertion of lamp/withdraw from respectively at the two ends of protective case 1.Near the opening of opening 2 (2a, 2b) complete cycle forms a plurality of holes 3 (3a, 3b) respectively.In each hole 3 (3a, 3b), make rope 4 (4a, 4b) with from the external-to-internal of cover, more internally to the mode of outside alternately change direction of insertion with respect to adjacent hole and at the complete cycle of opening by each hole, form the such structure of so-called pocket rope.The adjustment means 5 (5a, 5b) of the size (the degree of tightness situation of pocket rope) of regulating opening is installed at each rope 4 (4a, 4b).Be formed with the heavy section 6 that extends along the total length direction at protective case 1.
Fig. 2 represents the state that the protected cover 1 of discharge lamp L covers.Protective case 1 covers the illuminating part L10 of discharge lamp L fully, and covers about half at the length direction of sealing L11.Under this state, protective case 1 becomes the state of fastening with respect to discharge lamp L, and when keeping, transportation discharge lamp L, the protection luminotron can not stay scar, spot.In addition, in this figure, omit hole and heavy section.
State when Fig. 3 represents to be installed to concave mirror M by the discharge lamp L that protective case 1 covers.
At first, before discharge lamp L is inserted the inside of concave mirror M, unclamp the pocket rope structure so that the upper opening 2a of protective case 1 (installation side end) opens by adjustment means 5a.Lower openings 2b still tightly ties up on the sealing of discharge lamp L.
Next, discharge lamp L is inserted the inside of concave mirror M and is installed to carriage H.During installation, because the lower openings 2b of protective case 1 closes, thereby the situation of undesirable position deviation can not occur coming off, producing from lamp in adorning operation, can avoid contacting of discharge lamp L and concave mirror M.In addition, the structure of light supply apparatus is identical with device shown in Figure 7, further, with Fig. 2 similarly, heavy section omits diagram.
Fig. 4 represents to be installed to by the discharge lamp L that protective case 1 covers the state behind the concave mirror M.At this moment, unclamp the pocket rope structure so that the lower openings 2b of protective case 1 opens by adjustment means 5b.The state that upper opening 2a maintenance has been opened.
At this, because the upper opening 2a of protective case 1 unclamped before concave mirror M that discharge lamp L is packed into, thereby do not need hand is stretched into the operation that the pocket rope structure is unclamped in the gap of discharge lamp L and concave mirror M.Lower openings 2b is near the front openings of concave mirror M, even thereby also can remove the pocket rope structure simply after discharge lamp is installed.
Fig. 5 represents state that protective case 1 is taken off from discharge lamp L.Because upper opening 2a and lower openings 2b all are in the state of opening, therefore only need protective case 1 is extracted out from the below, just can simply protective case 1 be taken off from discharge lamp L.Further, owing to form heavy section 6 at protective case 1, therefore can not produce shape distortion etc. and make and extract operation out and become and be more prone to.Further, because the just simple operation that protective case 1 is extracted out from the below, thereby can not be created in the field-strip of protective case 1 problem that stays scar at mirror mirror, adheres to spot.
Like this; lamp of the present invention covers discharge lamp until discharge lamp is installed to concave mirror with protective case; thereby can protect discharge lamp not stay scar, spot, and in addition, even under the situation of contingency discharge lamp breakage, also can live fragment by the good geosphere of protective case.
Therefore in addition, protective case is installed on the discharge lamp by the pocket rope structure, has that when installation remains on the discharge lamp and can extremely simple advantage during dismounting.
Further, on protective case, form heavy section as pillar performance function in the mode of extending along its length, thereby in field-strip, can prevent the alteration of form of bending or fold.
Heavy section can make by the material that constitutes this protective case partly to be thickeied and forms, and also can add miscellaneous part and thickeies.In a word, need make protective case that the polyurethanes resin has flexibility like this stand up in as shown in Figure 1 mode that Shi Buhui falls down or bending.
Perhaps, also as shown in Figure 6, also a cylindraceous raw-material part that constitutes this protective case can be turned back and overlapping and sew up by heat treatment.
Further, also can the adhesion metal silk etc. hard material.
Consider above-mentioned characteristic, the Young's modulus of preferred protective case 1 is 0.01～0.5GPa, for example can be suitable for polyurethane (Young's modulus is 0.04GPa), polyethylene (Young's modulus is 0.2GPa), (Young's modulus is 0.01～0.1GPa) to rubber.In addition, the value of the thickness of protective case in the scope of 0.2～0.6mm, selecting, the value of heavy section in the scope of 0.8～3.0mm, selecting.Under the situation of the protective case with such numerical value, yield stress is 8N/mm
2, 15N/mm
2, 30N/mm
2The time, can easily shrink by the pocket rope structure, in addition, the situation of bending or fold can not appear when mounted.
The size of protective case is that for example internal diameter is that Φ 78mm, length are 220mm.Above-mentioned size decides according to the size of discharge lamp, is suitable for following size: internal diameter is that value, the length bigger slightly than the maximum outside diameter of the illuminating part of discharge lamp covers fully and further covers about half of sealing for the illuminating part with discharge lamp.In addition, protective case 1 has flexibility, when not using through folding and become tabular.In addition, for example form eight holes that constitute the pocket rope structure at circumferencial direction.
Preferred in the present invention, heavy section does not overlap with the hole of pocket rope structure.Thereby this is may cause obstacle to the movement of rope because make the formation in hole become insufficient easily.
In addition; in the above-described embodiments; used the statement of upper opening, lower openings for protective case; in fact; direction of insertion when discharge lamp is inserted concave mirror determines; as Fig. 3, Fig. 4, shown in Figure 5, be that opening surface (light emission face), below are under the situation at top above concave mirror is configured to, then as embodiment, become the surface of upper opening, lower openings.But, for example concave mirror be configured to opening surface towards below under the situation of (that is, be configured to light and radiate downwards), when discharge lamp is installed to concave mirror, open and the upper opening closing state is carried out with the lower openings of protective case.
Lamp of the present invention not only is applicable to high pressure mercury vapour lamp with protective case, and can be applicable to that xenon lamp, metal halide lamp or filament lamp etc. are installed to all lamps of the structure of concave mirror.
