Abstract: A blue light leakage-suppressing LED structure for emitting white light includes at least one LED chip, an encapsulation element, a light output lens, and an optical fuse coating formed of a thermosensitive material; or includes at least one LED chip and an encapsulation element formed of a mixture of an encapsulation material and a thermosensitive material; or includes at least one blue LED chip, a fluorescent powder layer, an isolation region, an optical fuse layer, and a light output lens. Thanks to the hue changing property of the thermosensitive material, the LED structure can reduce the intensity of its short-wavelength light component and its overall brightness significantly before reaching the L70 threshold, after passing which the LED structure will emit excessive blue light. Thus, the user is protected from overexposure to blue light and will be reminded to replace the LED structure when the LED structure is about to malfunction.

Abstract: Conjugates of fluorescent labels with specific, selective, and high affinity ligands for receptors have been synthesized and used to directly measure binding to receptors. In the examples, fluorescein conjugates of the high-affinity benzodiazepine receptor ligands Ro 15-1788 and Ro 7-1986 were synthesized. The binding of these fluorescent ligands (BD 621, BD 623 and BD 607) to benzodiazepine receptors was characterized by direct fluorescence measurement. Both the equilibrium dissociation constants (K.sub.D) of BD 621 and BD 607 and the maximum number of binding sites (B.sub.max) estimated by fluorescence monitoring were consistent with values obtained by using radioligand binding techniques. The binding of BD 621 and BD 607 assessed by fluorescence measurement was reversible, abolished by photoaffinity labeling with Ro 15-4513, and unaffected by a variety of substances that do not bind to benzodiazepine receptors.
