Philips Infraphil 1945 - 2012
the Infraphil brand
Infraphil is the general brandname for a family of heat lamps for self-medication, manufactured and marketed by Royal Philips Electronics. On the Infraphil products, a Philips wordmark or -logo could always be found on the armatures, the packaging, the user manuals and on the heat lamps itself. Apart from that, the brand name Infraphil was printed on the packaging, the user manual and the heat lamp but it was not until 1980 that the brand name Infraphil was printed on the armatures too.
the Philips logo and -wordmark
The style of the Philips logos on the Infraphil products reflected the development of the Philips logo over the years. At first Infraphil armatures only carried the early circular logo with the three waved lines and the two pairs of stars. This logo had been registered as a Philips trademark in 1934 but since it resembled the logo of the British company ICI (Imperial Chemical Industries) too much, Philips registered in 1948 the now famous shield emblem with the stars, the waves and the wordmark Philips.
Although the new shield emblem was used for the Infraphil products too, the original circular logo was maintained throughout the entire 752-series with exception of the 7525N that from the beginning was equipped with the red and gold shield emblem only. The Philips wordmark was initially used on the packaging and in the user manuals only. It was not until 1960 that this logo was introduced the newer armatures of the KL7500-series.
the Infraphil logo and -wordmark
Apart from the Philips logo and wordmark, Philips also used a dedicated logo or wordmark on their Infraphil products. From 1948 on a logo was used that consisted of a rectangle with rounded corners with the brand name infraphil in it. On the first letter i of infraphil was a star that partly jutted out of the rectangle. There were quite a few variations in style and colour and although the star most commonly had eight points, a variant with five points also had been used.
In 1962 the Infraphil logo was modernised by stretching the rectangle a little in the longitudinal direction and by introducing a sans-serif type of font that differed from that of the Philips wordmark. In the same period an experimental Infraphil wordmark without rectangle and star and with the same font as the Philips wordmark could be found but this lasted only a short period of time. From 1969 on the rectangle disappeared, leaving an Infraphil wordmark with an eight-pointed star on the first letter i.
Around 1975 the font of the Infraphil wordmark was replaced by a serif and italic type. The star disappeared and the first letter became a capital I. Remarkably this font was prominently used for the Philips trademark as well although the standard Philips wordmark and logo remained present on the same Infraphil products.

The serif Infraphil font was used until about 1983 when it was replaced by a red sans-serif italic font. About this time Philips started using an Infraphil wordmark on the armature as well, something that had not been done earlier. The fonts of the Infraphil wordmark on the subsequent armatures changed every few years and surprisingly differed from the fonts used on the belonging packaging and manuals.
Around 1990 the red italic font for the packaging was replaced by a non-italic font and again a new Infraphil wordmark for the armature was introduced. It is this logo that is present on the HP3614, the last Philips heat lamp to be sold under the brandname Infraphil. It had been available in Great Britain until the end of 2009. The logo is also used on the HP3616 that is available in Germany and Austria since 2012.
The Philips wordmark has been modernised in 2008. The characters are a little thicker and somewhat closer together, there is a difference in thickness between the horizontal and the vertical lines added, the P’s and the S are more round and open, the L is skewed at the lower right end and a deeper tint of blue has been used.
The renewal of the Philips wordmark coincided with the removal of the Infraphil brand name. Infraphil heat lamps have been produced since 2008 but without the brand name Infraphil on it.
