The test fixture comprises a pressure plate and a pedestal. The LED power conversion module is installed between the pressure plate and the pedestal. The pedestal is provided with an input thimble which fits with an input contact of the LED power conversion module to be tested and an output thimble which fits with an output contact of the LED power conversion module to be tested. Output of the power supply is electrically connected with the input thimble successively through the voltage regulator and the parameter measuring instrument. The output thimble is electrically connected with a power supply terminal of the LED lamp for the test. The LED power conversion module test system provided by the utility model has advantages of simple test process, high test result accuracy and fast test efficiency.
Description
Technical field
The utility model relates to a kind of LED power transfer module test macro.
Background technology
Light emitting diode, is called for short LED, is a kind of solid-state semiconductor devices that can be visible ray by electric energy conversion, and it can directly be converted into light electricity.It has energy-conservation, long service life, can be operated in the features such as fast state, environmental protection, shock-resistant and wide power voltage supply scope, therefore it is widely used in Building facade lighting, Landscape Lighting, sign and indicative illumination, interior space display lighting, the public place of entertainment place such as stage illumination, lighting, screen screen, automobiles indicator lamp illumination and domestic lighting in one's power.
Because the operating voltage of LED lamp is low, be generally 3V～24V, therefore, when LED lamp is worked, power supply voltage transitions need to be become to LED light working voltage, thus the work of driving LED lamp, LED power transfer module has been exactly the main circuit of voltage transitions.The stability of LED power transfer module and reliability are one of key factors guaranteeing the normal work of LED lamp, before LED lamp is assembled, need first to LED power transfer module, debug, to guarantee that LED power transfer module can normally work.Traditional method of testing, is mainly that after switching on power, whether observation test normally works with LED light fixture by LED power transfer module being connected between power supply and test LED light fixture, as normal work LED power transfer module to be measured can normally work.Traditional method of testing is by the observation test whether normal luminous test realizing LED power transfer module of LED light fixture, can complete to a certain extent the test to LED power transfer module, but, above-mentioned method of testing test result is single, the electrical parameter values such as voltage and current to LED power transfer module detects intuitively, can not reflect intuitively LED power transfer module each electrical parameter values under operating voltage, and traditional testing efficiency is low.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of test process simple, the LED power transfer module test macro that testing efficiency is fast.
The purpose of this utility model is achieved through the following technical solutions: LED power transfer module test macro, it comprises power supply, pressure regulator, parameter measurement instrument, test fixture and test LED light fixture, described test fixture comprises pressing plate and base, LED power transfer module to be measured is installed between pressing plate and base, base is provided with the input thimble matching with LED power transfer module input to be measured contact and the output thimble matching with LED power transfer module output contact to be measured, the output of power supply is electrically connected with input thimble by pressure regulator and parameter measurement instrument successively, output thimble is electrically connected with the power end of LED light fixture with test.
The beneficial effects of the utility model are: by test, use LED light fixture and parameter measurement instrument can reflect intuitively whether LED power transfer module to be measured normally works and the electrical parameter values such as electric current, voltage, power factor and the power of LED power transfer module to be measured while normally working, make test result more accurate; Test process is simple, and test result accuracy is high, and testing efficiency is fast.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, LED power transfer module test macro, it comprises power supply, pressure regulator, parameter measurement instrument, test fixture and test LED light fixture, described test fixture comprises pressing plate and base, LED power transfer module to be measured is installed between pressing plate and base, base is provided with the input thimble matching with LED power transfer module input to be measured contact and the output thimble matching with LED power transfer module output contact to be measured, the output of power supply is electrically connected with input thimble by pressure regulator and parameter measurement instrument successively, output thimble is electrically connected with the power end of LED light fixture with test.
The course of work of the present utility model: tester is placed on LED power transfer module to be measured on the base of test fixture, pressing plate presses down LED power transfer module to be measured, its input contact is contacted with the input thimble on base, output contact contacts with the output thimble on base, if shown electric current I on the display screen of the normal work of LED light fixture and parameter measurement instrument for now test, voltage V, power factor PF and power W value are normal value (being judged according to technical indicator by tester), LED power transfer module to be measured is certified products, otherwise be substandard products.In test process, by regulating pressure regulator parameter, change the magnitude of voltage being input in test macro, thereby record the each electrical parameter values of tested LED modular converter under different input voltages, thereby make measurement result more accurate.
The above is only preferred implementation of the present utility model, be to be understood that the utility model is not limited to disclosed form herein, should not regard the eliminating to other embodiment as, and can be used for various other combinations, modification and environment, and can, in contemplated scope described herein, by technology or the knowledge of above-mentioned instruction or association area, change.And the change that those skilled in the art carry out and variation do not depart from spirit and scope of the present utility model, all should be in the protection domain of the utility model claims.
