Description
Technical field
The utility model relates to LED manufacturing fields, and in particular to a kind of for testing the substrate of LED chip.
Background technique
LED is the english abbreviation of light emitting diode, is a kind of solid semiconductor device, it can directly be converted into electric energy
Light.As the improvement of people's living standards, the development of city lighting engineering and freeway net, to room lighting, road lighting
And the requirement of the floodlighting of building increasingly improves, therefore gets over to the demand of various LED lighting sources and LED lamps and lanterns
Come bigger, it is desirable that it is also continuously improved, while also having pushed the rapid development of LED illuminator industry, it is various efficient, energy-efficient
LED light also continuously emerges.How is the quality of evaluation any one LED lamps and lanterns, it is important to see it in practical application
In which type of illuminating effect and actual service life can be reached, only generate good illumination effect and tool in practical applications
There is the LED lamp of long service life to be only good lamps and lanterns.
LED lamp needs one of detection process before factory, and undesirable LED light is rejected.And previous LED chip electric leakage
In detection, it can only be detected for the drain conditions of multiple LED chips, not can be carried out the detection of single LED chip.
Summary of the invention
The technical problem to be solved by the present invention is to provide it is a kind of it is reasonable in design, can be to more and single
The substrate that the drain conditions of LED chip are detected.
In order to solve the above-mentioned technical problem, the utility model includes base main body, in the front and back point of base main body
Not She You front line layer and back side line layer, overleaf the both ends of line layer be equipped be respectively equipped with positive electrode and negative electrode,
Several electrode portions are equipped between positive electrode and negative electrode, the polarity of two adjacent electrode portions close to positive electrode on the contrary, and set
The polarity for the electrode portion set is cathode, and the polarity close to the electrode portion of negative electrode setting is anode, is corresponded to just in base main body
Via hole is equipped at the position of electrode, negative electrode and electrode portion.
Conducting connector is equipped in the via hole as a further improvement of the utility model,.
The conducting connector is conducting wire as a further improvement of the utility model,.
The conducting connector is that note copper forms conductive column in via hole as a further improvement of the utility model,.
The quantity of the electrode portion is two as a further improvement of the utility model,.
The base main body is ceramic substrate ontology as a further improvement of the utility model,.
The utility model has the beneficial effects that the front route that will need plurality of LEDs chip to be tested that base main body is arranged in
On layer, while being connected with corresponding positive electrode, negative electrode and electrode portion, by test equipment, such as digital display DC regulated power supply,
It is connect with the positive electrode at base main body both ends and negative electrode, to test the drain conditions of plurality of LEDs chip, when test data exists
When abnormal, test equipment electrode portion corresponding with single LED chip can be connected and test the electric leakage feelings of single LED chip
Condition is easy to detect quick.
Detailed description of the invention
It is next with reference to the accompanying drawings and detailed description that the utility model is described in more detail.
Fig. 1 is the front view of the utility model.
Fig. 2 is the rear view of the utility model.
Fig. 3 is that the schematic diagram of base main body is arranged in the LED chip of the utility model.
Specific embodiment
Fig. 1 to Fig. 3 is the embodiments of the present invention:
Including base main body 1, front line layer 2 and back side line layer are respectively equipped in the front and back of base main body 1
3, overleaf the both ends of line layer 3 are equipped with and are respectively equipped with positive electrode 4 and negative electrode 5, are equipped between positive electrode 4 and negative electrode 5
First electrode portion 6 and second electrode portion 7, and the polarity close to the first electrode portion 6 that positive electrode 4 is arranged is cathode, close to negative electricity
The polarity in the second electrode portion 7 that pole 5 is arranged is anode, and positive electrode 4, negative electrode 5, first electrode portion 6 are corresponded in base main body 1
With at the position in second electrode portion 7 be equipped with via hole 8, in via hole 8 be equipped with conducting connector.
According to the structure of the substrate, three LED chip to be tested, respectively the first LED chip 9, the second LED core will be needed
Piece 10 and third LED chip 11, are arranged on the front line layer 2 of base main body 1, the first LED chip 9 respectively with positive electrode 4,
First electrode portion 6 connects, and the second LED chip 10 is connect with first electrode portion 6, second electrode portion 7 respectively, third LED chip 11
It is connect respectively with second electrode portion 7, negative electrode 5, by test equipment, such as digital display DC regulated power supply, with 1 liang of base main body
The positive electrode 4 and negative electrode 5 at end connect, to test the drain conditions of plurality of LEDs chip, when needing to detect the first LED chip 9
When drain conditions, test equipment connection positive electrode 4, first electrode portion 6, test of other LED chips and so on, entirely
Detection process is convenient and efficient.
