Description
Technical field
The test of optical device is the utility model is related to, it particularly relates to the test of LED light source board.
Background technology
It is well known that as the popularization of LED illumination lamp and permanent use prove that Switching Power Supply quality has become certainly
Determine the key factor of LED life.And the manufacturing cost of Switching Power Supply limits the price of LED illumination lamp.Industry starts to abandon out
Powered-down source has become common recognition.Power LED is gone mainly there are two kinds：1. extraneous drive LED side with linear constant current IC chip
Formula;2. in a manner of CRD drivings LED.Both of which greatly simplifies the structure of LED lamp, and production procedure is simple, installation letter
Just.But a problem is also brought simultaneously:The problem of how substandard products being measured when light source board is produced in batches.Due to being 220 friendships
LED is lighted in stream civil power direct drive, and there has been no special Hi-pot test instrument for industry at present.And PCB light source plate can only lean on single-handedly
The measures such as coordinated insulation gloves are tested, and bring great personal safety to threaten to tester.
Industry is tested using card pin type at present, but card pin type testing jig has the disadvantage that:(1) card pin position is fixed not
Become, regulation inconvenience.And it is suitable for the contact node test of proper alignment, be not suitable for single light source board test.Particularly when repairing
In the case of substandard products, card pin testing jig is not used completely;(2) card pin testing jig is heavy, is unfavorable for moving;(3) connecting test pin
Line is easily damaged after permanent flexible test, is made testing jig conductive, is brought potential safety hazard.
To solve the problems, such as that existing LED light source board test is present, people work out《A kind of test machine of LED light source board》
（Chinese patent application part 201510114626X）, it is to realize LED light source board brightness detection automation to ask purpose；Also push away afterwards
Go out《A kind of LED light source board test device》（Chinese patent 2016209071505）, it includes testboard and positioning group
Part, multiple testing needles is provided with testboard, testing needle is connected to controller by wire, multiple tests are provided with testboard
Pin fixed structure, testing needle are set on testing needle fixed structure at an arbitrary position ....Though above technology can be to LED light source board
Tested, but these technical schemes have the shortcomings that complicated, and not only cost is high, and inconvenient for use.So far
Have no and be born for the special Hi-pot test instrument of LED light source board.
The content of the invention
The utility model aims to provide one kind and removes power supply LED light source board test pen, to overcome existing LED light source board to test
The shortcomings that device, so as to simplify testing process, improve testing efficiency, especially be ensure tester life safety.
What designer provided removes power supply LED light source board test pen, is made up of each one-pen bar in left and right and wire；On penholder
One spherical portion, spherical portion exterior key switch, built-in intelligent control circuit module, intelligent control circuit module difference are arranged at portion bottom
It is connected with wire and key switch；It is human body sensing shell in the middle part of penholder, the shell has wire to connect intelligent control circuit mould
Block；Penholder bottom is the test nib of ambroin parcel, and the testing needle that test nib is made of metal, testing needle one end is in pen
Bar in-core is connected with intelligent control circuit module, and the other end, which exposes, makees probe.
The circuit of above-mentioned intelligent control circuit module is MCU Intelligent control electric PCBs.It is the Master Control Center of test pen,
Mainly there are following functions：1. receiving key switch instruction, the role of this branch pen is determined --- the output of-selection live wire or zero line are defeated
Go out；2. the output of live wire or zero line input as connection nib is selected according to the Role Dilemma relay of this branch pen；3. basis
The capacitance variation of human body sensing shell, determine whether human contact's pen；When there is human body contact pen, relay connects zero line
Or live wire；When human body and penholder depart from, relay disconnects, a no power.
Above-mentioned wire wrapped with insulation, outer layer wrap up a screen layer again, prevent the electric capacity of Hz noise penholder shell
Change.
The internal layer of above-mentioned human body sensing shell is that ito glass, outer layer are resistant polyester films；Internal layer is led with outer layer with ITO
Electrocoat is bonded into one.
The partial-length that above-mentioned test nib exposes is 1mm；Plastic wraps test nib plays a part of fixed nib.
The application method and principle for removing power supply LED light source board test pen be：The pen of left and right two is used simultaneously, and wire is inserted
Head insertion 220V mains power sockets, grasp penholder and are contacted with contact point, open respective key switch, by nib pair
Quasi- contact needs the test point for the LED light source board tested, now because human body electric field, human body are formed with shell inner conductor coating
Inductively electric capacity；Upper and lower ends electric current can flow to contact surface position, and this curent change can have MCU control centres sensor
Detect, MCU judges whether that human body has contact, determines whether nib is powered so as to judge whether LED light source board is working properly.
The utility model possesses advantages below：1. small volume, portability is strong, facilitates simple and direct；It is 2. safe：Due to working as people
Body departs from pen in a flash, automatically powers off, test pen can be put everywhere.In the absence of electric leakage risk；3. power supply can be greatly improved
High-voltage LED light sources plate production efficiency, improve test speed.Suitable for the test to LED light source board, also extend to needs
The energization test of the product of 220V Alternating Current Power Supplies.
