The invention discloses fluorescent materials with an aggregation-induced emission effect and circular polarization and a preparation method of the fluorescent materials. The general structural formula of the fluorescent materials is shown in the description, wherein R represents any one of H, phenyl, C1-C2 alkoxy substituted phenyl, C1-C3 alkyl substituted phenyl, trifluoromethyl substituted phenyl, thienyl, C1-C3 alkyl substituted thienyl and triphenylamine. After a ring-locking o-dinaphthol intermediate is synthesized from o-dinaphthol and 1,6-diiodohexane, a coupled product is synthesizedthrough a Suzuki coupling reaction, finally, an aldehyde group and malononitrile are subjected to a reaction, and the fluorescent materials are obtained. The fluorescent materials realize aggregation-induced emission characteristic and chirality in one molecular framework and can prevent quenching of circular dichroism spectrum, namely, the AACD effect, and by use of the two properties, microcrystals with different morphologies are obtained by self-assembly of the synthesized fluorescent materials, so that the compounds realize spectrum-adjustable circularly polarized light.

The invention discloses an LED lamp with the light color adjusting function. The LED lamp comprises a lamp holder, a lamp body and a handle, wherein three LED lamp sets are arranged in the lamp holder and each LED lamp set comprises a high color temperature LED string and a low color temperature LED string. An adjustable drive module, a light color adjusting module and a rechargeable battery are arranged in the handle, and the handle is connected with the lamp body via a multi-shift adjustable rotary knob. The light color adjusting module comprises two brightness adjusting rotary knobs and three dial switches which work together to control the lamp to emit lights with high color temperature, low color temperature and moderate color temperature between the high and low color temperatures, as a result, the adjustment of the color temperature, the spectrum and the brightness can be realized. According to LED lamp disclosed by the invention, the light control signal generation circuit has a simple structure, the linearity of the operation signal is good, the lamp is widely applicable for indoor purposes and outdoor occasions without external power sources and in need of extensive light adjustment of multiple lamps, and further, the modular structure of the lamp brings convenience in installation, maintenance and light emitting angle adjustment.

The invention discloses a light source structure for testing CIS products based on general ATE, including an LED light source box and a controller, an ATE interface board and a fixed structure; LEDs are installed in the LED light source box, and the controller is used to control the LED output to meet the test conditions. Light source; there are control chips and circuits in the controller to realize the function of controlling LEDs, and the ATE interface board is a PCB connecting ATE and chips; the light source structure based on general ATE testing CIS products provided by the present invention, a complete set of external equipment , the installation does not need to change the ATE structure. Even if there is a problem with the light source, it can be replaced in a short time without turning off the ATE. It saves time and cost, is easy to transform, and is suitable for mass production.
