The light baffle defines a plurality of through holes. The laser spot light of the invention utilize a motor driving a light baffle to rotate or translate, such that the static light spots generated by the first grating are blocked and unblocked alternately, resulting a lot of twinkling light spots.
Abstract:
The present invention provide a constant current and temperature compensation control device for outdoor spotlights used on laser stages which includes a single chip microcomputer, a triode or an field effect transistor, a laser LED light, a heating piece and a driving triode used for driving the heating piece. The benefits of the present invention include protecting the laser light from damage caused by power surge which results in no light or weakened light intensity, saving the cost of a specialized current limiting chip, making the green laser module work normally in extremely cold outdoor environment thus being more favorable to apply this device to mood creating lights of Christmastime.

Abstract:
The present invention provides a projection light with color film including a light source, a color film which can resist a temperature higher than 80 degrees Celsius without deformation and color fading, a film support configured for retaining the color film, a light guide column configured between the film support and the light source and configured for transmitting light from the light source to the color film, and a lens configured at a side of the color film and for receiving light passing through the color film. By using the PET material, the film base of the color film 40 has the ability to resist a high temperature up to 120 degrees Celsius. By using anti-uv screening inks, the printing layers do not easy to color fade. Therefore, the color film can operate properly without deformation and color fading during its lifetime.

Abstract:
A new class of chemiluminescent acridinium or benzacridinium compounds is disclosed by virtue of forming an intramolecular energy transfer conjugate (ETC) between the acridinium or benzacridinium compound and a luminophore. A method of extending the emission wavelengths of acridinium or benzacridinium esters in order to further reduce or eliminate the emission spectral overlap between the parent polysubstituted aryl Acridinium Esters (DMAE) and Benzacridinium Esters (LEAE) is disclosed. The ETC's retain the unique desired properties of acridinium or benzacridinium compounds including complete light emission in very short period of time, monophasic emission spectrum, simplicity of triggering mechanism, ability of labeling the biological molecules of interest to form a tracer, and good stability. Additionally, the range of the emission spectrum of an acridinium or benzacridinium compound can now be shifted at will and at longer leap through the choice of a luminophore as the integral part of an ETC molecule. Disclosed are chemiluminescent labeled conjugates comprising an acridinium or benzacridinium moiety covalently attached to a luminophore via a spacer, said moiety further conjugated to a biological molecule of interest, wherein said spacer is of an appropriate length to allow the excited species generated from said moiety to transfer energy efficiently to said luminophore, resulting in the emission of light in the spectral region of said luminophore. Also disclosed are binding assays using said conjugates, test kits comprising said conjugates and methods of preparing the conjugates.
Abstract:
An assay method incorporating at least two different chemiluminescent compounds for detection and/or quantitation of at least two substances in a test sample is described. The synthesis of chemiluminescent reagents or conjugates for use in such methods as well as kits incorporating such reagents are also disclosed. The assays have particular application in the field of clinical diagnostics.
