A light apparatus for generating a mixed light output. The light apparatus includes multiple LED modules. Each LED module includes multiple LED regions. The multiple LED regions have separate electrodes. The multiple LED regions share the same package housing but at least two LED regions are covered with different fluorescent layers for emitting lights with different optical characteristics.

LED light apparatus

A hybrid light emitting device includes a full-wave bridge rectifier, an AC-to-DC converter, a hybrid illumination module, a luminance control module and a linear constant current circuit. The full-wave bridge rectifier transforms a full sinusoidal wave voltage into a positive half sinusoidal wave voltage. The AC-to-DC converter is electrically coupled to the full-wave bridge rectifier. The AC-to-DC converter transforms the positive wave voltage into a constant DC voltage. The hybrid illumination module includes a plurality of illuminating elements having different or partially same luminance properties. The plurality of illuminating elements are disposed in respective proximities. The luminance control module generates a plurality of control signals that determine the duty cycles of the plurality of illuminating elements. The linear constant current circuit controls duty cycles of the plurality of illuminance elements using the plurality of control signals.

Loop-shaped primer used in nucleic acid amplification is an oligonucleotide with 3-20 bases in both 3' and 5&#x2032; ends which can be combined together to form a double-strand under appropriate conditions, resulting in the primer forming a stem-loop structure. The double-stranded structure is opened and the stem-loop structure dissolves when the primer recognizes and hybridizes with the target sequence. If the target sequence is not present the primer can form a stem-loop structure automatically by self-annealing. The primer can comprise a universal tag sequence or not. Together with universal tag sequence primer the primer comprising the universal tag sequence can be used for a second round of amplification. The primer has high specificity and does not form a primer dimmer. The primer is easy to design and is suitable for measuring gene expression and detecting features of nucleic acids such as SNPs and rare mutations.
