Abstract
The utility model provides an LED driver testing system, which can improve the safety of LED driver testing and comprises a test tooling box, a measuring instrument and a signal processing device, wherein the test tooling box is closed and internally provided with an electrical interface and a signal acquisition interface of an LED driver; the signal acquisition interface is electrically connected with the measuring instrument and the signal processing device; when the LED driver testing system is in testing, the LED driver is arranged in the closed test tooling box, thus being capable of avoiding safety accidents such as capacitive elements burns, scalds caused by explosion, explosive wounds and the like; and in the further technical scheme, the test tooling box is provided with a transparent top cover, thus leading a tester to intuitively observe the state of the LED driver to be tested.
Description
Technical field
The utility model relates to the detecting instrument technical field, relates in particular to a kind of led driver test macro.
Background technology
In recent years, along with people are energy-conservation to product, life-span and environmental protection requirement are more and more higher, LED (LightEmitting Diode, light emitting diode) serviceable life of product can be up to 50000 hours, and adopt lead-free and environmental protection materials such as technology, no mercury, thus, the LED product just will be widely applied to illumination market.
Guarantee that LED illumination gives full play to its inherent characteristic, the power-supply system of LED is also different with traditional light source, and the constant-current driving power supply that LED special procured is the important component part of LED illuminator.Simple Switching Power Supply scheme brings damage usually can for the LED device, and therefore, how assessing the led driver performance reliably is an important indicator investigating the LED illumination.
The LC element is the Primary Component that influences the led driver performance parameter.The LC element can get up electrical power storage, but its discharge needs the regular hour and just can finish, therefore, when led driver is tested with production test, if the LC element not rapid discharge finish, then operating personnel's contact will cause Danger Electric shock risk, in addition, led driver is when test, and the LC element burns because of the transient voltage variation produces easily, explosion phenomenon, cause security incidents such as burning, wound, thereby threaten implementer's personal safety.
The utility model content
In view of this,, the utility model proposes a kind of led driver test macro, can improve the security of led driver test in order to address the above problem.
The purpose of this utility model is achieved in that the led driver test macro, comprise test fixture case, measurement instrument and signal processing apparatus, described test fixture case is airtight, be provided with led driver electric interfaces and signals collecting interface in the test fixture case, described signals collecting interface is electrically connected with measurement instrument, signal processing apparatus.
Further, described test fixture case comprises a transparent cap;
Further, described led driver test macro also comprises lifter, and described lifter is fixedlyed connected with transparent cap;
Further, described measurement instrument is a digital measuring instrument;
Further, described signal processing device is changed to computing machine;
Further, described led driver test macro also comprises audible-visual annunciator, described audible-visual annunciator and signal processing apparatus.
The utility model led driver test macro was installed on led driver in the airtight test fixture case in when test, can prevent that the capacitive element initiation of burning, explode from security incident such as burning, wound; In further technical scheme, described test fixture case is provided with transparent cap, can make the tester observe the state of tested led driver intuitively.
Other advantage of the present utility model, target, to set forth in the following description to a certain extent with feature, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantage can be passed through following instructions, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.
