Abstract
The invention discloses a detection device for an LED luminous chip. The detection device comprises a base, a sample detecting platform, a lighting source, a detection system, an intensity measuring instrument, a camera, an optical splitter and a computer processor. The LED luminous chip is detected by using a coaxial optical detection system, and light correspondingly enters the computer processor for analytic processing after the processing of the coaxial optical detection system; moreover, other image data are transmitted to the computer processor through the camera, corresponding light intensity measuring results can be measured and fed back to the computer processor, and final results are obtained after the analytic processing of the computer processor. The detection device is simple in structure, reasonable in design, convenient to install and use and wide in application range.
Description
Technical field
The present invention relates to LED detection technique field, particularly a kind of LED luminescence chip checkout gear.
Background technology
Led luminescence chip is the core component of LED lamp, the P-N junction namely referred to.Its major function is: be luminous energy electric energy conversion, and the main material of chip is monocrystalline silicon.Semiconductor wafer is made up of two parts, and a part is P type semiconductor, and inside it, occupy an leading position in hole, and the other end is N type semiconductor, at this side mainly electronics.But time these two kinds of semiconductors couple together, between them, just form a P-N junction.When electric current acts on this wafer by wire time, electronics will be pushed to P district, and in P district, electronics is with hole-recombination, then will send energy with the form of photon, the principle of LED luminescence that Here it is.And the wavelength of light i.e. the color of light, be determined by the material forming P-N junction, therefore when production LED, the detection for led luminescence chip is absolutely necessary the quality of production stage, the whole LED product of relation.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of LED luminescence chip checkout gear that can solve the problem.
