Abstract
A vibration damping device of a lamp comprises a base plate, an elastic pad and a butting member. A containing part is formed on the base plate, and a through hole is formed in the bottom surface of the base plate. The elastic pad is contained in the containing part. The butting member comprises a tope plate and a lateral plate, wherein the lateral plate penetrates the through hole to be fixedly connected with the lamp, and the top plate butts against the elastic pad. When the outside vibrates, external force is exerted on the lamp, the integrity composed of the lamp, and the butting member and the elastic pad can move within certain range due to extension and contraction of the elastic pad, so that most energy can be absorbed by the elastic pad, and only a small amount of energy can be transmitted to the lamp. Therefore, the vibration damping device of the lamp can effectively reduce vibration and improves the integral vibration resisting capability.
Description
Technical field
The present invention relates to lighting technical field, particularly relate to the vibration absorber of light fixture.
Background technology
In some special occasions, on harbour, harbour or crane, working environment is unstable, often is attended by violent vibration.General light fixture when using in above-mentioned environment, because damping capacity is poor, is very easy to produce and damages.When therefore using in above-mentioned environment, greatly reduce the service life of light fixture, in use needs to change frequently light fixture, is difficult to satisfy client's requirement.

Fig. 2 is the schematic diagram of base plate of the vibration absorber of light fixture shown in Figure 1.
The specific embodiment
For the ease of understanding the present invention, the below is described more fully the present invention with reference to relevant drawings.Provided preferred embodiment of the present invention in the accompanying drawing.But the present invention can realize with many different forms, be not limited to embodiment described herein.On the contrary, provide the purpose of these embodiment be make the understanding of disclosure of the present invention more comprehensively thorough.
Need to prove, when element is called as " being fixed in " another element, can directly can there be element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be to be directly connected to another element or may to have simultaneously centering elements.
Unless otherwise defined, the employed all technology of this paper are identical with the implication that belongs to the common understanding of those skilled in the art of the present invention with scientific terminology.Employed term is not intended to be restriction the present invention just in order to describe the purpose of specific embodiment in specification of the present invention herein.Term as used herein " and/or " comprise one or more relevant Listed Items arbitrarily with all combinations.
See also Fig. 1 and Fig. 2, the vibration absorber 100 of the light fixture of preferred embodiment of the present invention comprises base plate 110, cushion 120, pressure holding piece 130, shield 140 and keyset 150.Vibration absorber 100 can be applied to the light fixtures such as lamp affixed to the ceiling, wall lamp, in the present embodiment, describes as an example of the vibration damping that is used for lamp affixed to the ceiling example.
Cushion 120 is roughly rectangular build, and is contained in the resettlement section 111.Deformation can occur in cushion 120 under the effect of external force, be used for absorbing energy.In the present embodiment, cushion 120 is rubber blanket, and can increase as required the number of plies of rubber blanket, when the vibration of application scenario is more violent, can increase the number of plies of rubber blanket, thereby increases the endergonic ability of cushion 120; When the vibration less of application scenario, then can reduce the number of plies of rubber blanket.It is pointed out that in other embodiments, but cushion 120 can also be spring pad or other energy storing structures, same, also can according to the difference of application scenario, select the different spring pad of stiffness factor.
In the present embodiment, also be provided with screw thread on the support bar 115, support bar 115 cooperates with nut, can be with cushion 120 and pressure holding piece 130 pressure holdings on the bottom surface of base plate 110.The pre compressed magnitude of cushion 120 can be by the extent control of tightening of nut, it is tighter that nut is twisted, the pre compressed magnitude of cushion 120 is larger, cushion 120 more is not easy to occur flexible, be more suitable for vibrating violent occasion, in vibration when violent, violent rocking can be because not occuring in cushion 120, and lose the effect of vibration damping; It is more loose that nut is twisted, and the pre compressed magnitude of cushion 120 is less, and cushion 120 more easily occurs flexible, is more suitable for vibration than the circlet border, and when small vibration was namely arranged, cushion 120 namely can stretch, and absorbed energy.The mode that it is pointed out that control cushion 120 pre compressed magnitudes is not limited to the mode that screw thread cooperates with nut, can also adopt other modes, as offering jack at support bar 115, utilizes the pre compressed magnitude of controlling cushion 120 that cooperates of latch and jack.
One end of keyset 150 is fixedly connected with the side plate 133 of pressure holding piece 130, and the other end is used for fixedly light fixture.In the present embodiment, light fixture is fixedly connected with by keyset 150 with pressure holding piece 130.In other embodiments, keyset 150 can omit, and directly light fixture is fixed on the side plate 133 of pressure holding piece 130.In addition, keyset 150 is bolted connection with pressure holding piece 130.Bolted connects more firm, when vibrating more violent applications, can prevent effectively that keyset 150 and pressure holding piece 130 from coming off, thereby damage light fixture.In other embodiments, also can be in other modes of employing.Such as the mode of engaging, the hinged fixed transfer plates such as mode 150 and pressure holding piece 130.
During mounted lamp, the installing plate of light fixture is fixed on the keyset 150, and base plate 110 is fixed in the position that needs mounted lamp.When extraneous vibration, the integral body of cushion 120, pressure holding piece 130, keyset 150 and light fixture can along support bar 115, move in the host cavity that shield 140 and base plate 110 form, thereby most energy is absorbed by cushion 120.
The vibration absorber 100 of light fixture comprises base plate 110, cushion 120 and pressure holding piece 130.Be formed with resettlement section 111 on the base plate 110, and on the bottom surface of base plate 110, also offer through hole 113.Cushion 120 is contained in the resettlement section 111.Pressure holding piece 130 comprises top board 131 and side plate 133, and side plate 133 passes through hole 113, and can be fixedly connected with light fixture, and top board 131 pressure holdings are on cushion 120.Work as extraneous vibration, when light fixture is subject to External Force Acting, the integral body that is formed by light fixture, pressure holding piece 130 and cushion 120 since the effect of cushion 120 will move within the specific limits, thereby most of energy is absorbed by cushion 120, only having seldom, a part can pass to light fixture.Therefore, utilize the vibration absorber 100 of above-mentioned light fixture can reach effective vibration damping, improve the purpose of the whole vibration resistance of light fixture.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
