Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the process flow diagram of the light fixture method for testing vibration that the preferred embodiment of the present invention provides.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
See Fig. 1, be a kind of light fixture method for testing vibration of preferred embodiment in the present invention, comprise the following steps.
Step S1, provide a light fixture.The lamp power provided in present embodiment is 1000W, and this light fixture is used on harbour, harbour bank bridge, carries out vibration test in the engineering prototype reliability stage of this product.
Step S2, check that described light fixture is whether normal, comprise and check that described light fixture whether can normal luminous work and check whether firm each secure component of described light fixture connects.
First checking that described light fixture whether can normal luminous work, if this light fixture can not normal luminous work, its performance i.e. existing defects itself being described, without the need to carrying out next step test.
If light fixture can normal luminous work, then check that whether each secure component of described light fixture connects firm, avoids namely there is secure component before the test and connect insecure situation, ensure test accurately and reliably.
Step S3, carry out frequency sweep vibration-testing to described light fixture, its vibration frequency back and forth changes between first frequency value and second frequency value, and wherein first frequency value is 5 ± 3Hz, and second frequency value is 30 ± 5Hz.Amplitude is 0.5mm ~ 0.8mm, and the frequency multiplication of sweep velocity is 0.5 ~ 1/oct, and continues a Preset Time.
In this step, for the ease of carrying out frequency sweep vibration-testing, the frequency sweep vibration-testing that a shaking table carries out light fixture can be utilized.Certainly, as other embodiment, frequency sweep vibration table also can be utilized to carry out frequency sweep vibration-testing.
