Product Information

Marvin Pipkin (November 18, 1889 – January 7, 1977) was an American chemist, engineer, and scientist. During his time in the United States Army, he worked on gas mask innovations. These masks were used by soldiers as well as the public during World War I for protection against chemical weapons. His innovative improvements were used through the twentieth century. Pipkin in 1947 invented an improved version of the process with silica coating that replaced the internal acid etching process. [22] The 1947 internal silica coating was used for 30 years and had the trade name "Q coat". [23] [24] [25] [2] Pipkin is also credited with perfecting the photo flash bulb with several patents. [5] Besides the frosted light bulb, Pipkin invented or improved many other products during his career with General Electric. One was for a toy light that could be used on a child's toy train or toy car. [26] Pipkin's innovations were noted in articles in Time, Newsweek, and the Saturday Evening Post magazines, as well as in scientific journals.

Unlike frosted bulbs that have an interior coating, clear bulbs just like their name do not have any special coatings. That is why clear bulbs produce light that is brighter than frosted bulbs and is suitable for everyday applications. If the light fixture you have doesn’t have shades, leaving the bulb exposed, then clear bulbs are a clear choice. You can use clear bulbs for different modern lights to enhance the ambiance of your room and serve as a great lighting option. Soft Light Inventor Dies". The Tampa Tribune. Tampa, Florida.

When Pipkin went to work for General Electric he was assigned the supposedly impossible task of finding a way to frost electric light bulbs on the inside without weakening the glass. [8] [ unreliable source?] He was not aware that this assignment was considered a fool's errand, so he went about the task as if it were something that could be done. [9] [ unreliable source?] Pipkin produced an innovative acid etching process for the inside of the globe of an electric lamp so that it did not deteriorate the lamp glass globe. [10] [11] His was a two step acid process that etched the interior of glass with tiny crevasses on the first process like in the normal procedure, but he added a second acid step that caused soft, rounded dimples from the crevasses which gave the bulbs added strength. There was minimal loss of diffusion of light with his innovation. [9] It left the outside of the globe of the glass lamp smooth so that it did not hold dust like those etched on the outside. [12] [13] The first electric light bulb frosted on the inside with sufficient strength for ordinary handling that could be sold to the public was invented by Pipkin in 1925. [14] [15] [16] Patent No. 1,687,510 was issued to Pipkin on October 16, 1928, and by him assigned to his employer, General Electric Co. On November 5, 1945, however, the United States Supreme Court invalidated the patent, on the ground that the claimed invention was not sufficiently original. [17] In his civilian life, Pipkin invented a process for frosting the inside of incandescent light bulbs to cut down on the sharp glare, and to diffuse the light. This process had the side effect of making a stronger constructed glass envelope that held up well with ordinary handling. He went on to make many other inventions and further improvements to the light bulb. His patents were developed into General Electric's popular Soft-White bulb series that were mass-produced. He also had patents for the photo flash bulb.
