Abstract: A versatile head-to-foot wind and raincoat, which includes a coat body, a set of extension portions, pant coverings, fixing devices and retaining units. The pant coverings are respectively made from a soft lining cloth connected between hard waterproof cloths, and assume tubular form. Moreover, the fixing devices are respectively affixed to lower portions of the soft lining cloth, and provide a margin for the pant coverings to displace and extend without affecting free movement of extending and retracting the legs when wearing the pant coverings. Furthermore, when walking along a street, the street surface will not cause damage to the structure of the pant coverings. When the pant coverings are not needed, the extension portions, the pant coverings and the fixing devices can be folded away and retained in a retaining unit. Furthermore, a coat body and hat combination structure of the present invention includes a hat, a retaining portion, a retaining opening and a covering piece. The retaining portion is formed within a collar interlining of the coat body. When the rain hat is not needed, the hat can be folded and placed within the retaining portion without affecting aestheticism of the conventional collar. The covering piece covers the retaining opening, thereby providing functionality to prevent rainwater from seeping into the wind and raincoat. The hat is further configured with a hat brim that can extend over a sports cap worn by the user, thereby preventing the sports cap from getting drenched by rain. Lower portions of the coat body are furnished with transverse juxtaposed units, which form storing spaces after juxtaposing, and after folding the extension portions, the pant coverings and the fixing units, they are stored within the storing space. The original coat body of knee-length forms a jacket of hip length after mutual pairing of the transverse juxtaposed units. When it is not raining, the present invention is able to keep the body warm in cold weather. In addition, a covering unit is attached to an inner side of the coat body corresponding to the back of the user, which can completely cover the coat body after folding, thereby providing easy portability and storing away.

Title: Remote wavelength conversion in an illumination device
Inventor: HARBERS GERARD
IPC: F21V9/40
Filed: 2005-06-01
Abstract: An illumination device uses a wavelength converting element, such as a phosphor layer, that is physically separated from a light source, such as one or more light emitting diodes, a Xenon lamp or a Mercury lamp. The wavelength converting element is optically separated from the light source, so that the converted light emitted by the wavelength converting element is prevented from being incident on the light source. Accordingly, the temperature limitations of the wavelength converting element are removed, thereby permitting the light source to be driven with an increased current to produce a higher radiance. Moreover, by optically separating the wavelength converting element from the light source, the conversion and recycling efficiency of the device is improved, which also increases radiance.
