Definitions

  • the invention relates to a hair styling device for e.g. hair crimping, curling, perming and straightening.
  • EP2861096 discloses a hair shaping device for use for hair shaping comprising a number of radiation sources for hair shaping, and a control device for the emission of radiation.
  • FR 2 939 285 A1 discloses a system for treating a portion of a keratin fiber, said system comprising a light source and a detector informing the system about the characteristic of the fiber to be treated.
  • Embodiments of the invention are based on the following considerations. It is highly desired by the consumer to style hair without heat damage. For prior art hair styling (heating by conduction) the hair temperature is limited by the system. The hot plates are set at a maximum temperature. This is not the case for photo-thermal hair reshaping. Hair can easily be heated above a damaging temperature (> 180 °C). Therefor it is necessary to determine the hair temperature during the process. This needs to be done at local level since hair characteristics will influence the hair temperature. Hair characteristics are various, and different hair characteristics can occur within the same hair tress, e.g. as regards color, thickness, volume, alignment, etc..
  • Embodiments of the invention provide a hair styling device that comprises an optical radiation source for radiating hair, a sensor unit for measuring effects from radiating hair, and a feedforward control device for controlling the optical radiation source in dependence on a signal from the sensor unit.
  • the optical radiation source may produce a first flash having a first energy density that may be lower than required for photo-thermal hair reshaping, the optical radiation source being controlled to produce a subsequent flash in dependence on a sensor signal obtained in response to the first flash, which subsequent flash may have at least the first energy density.
  • the sensor unit may include a sensor arranged before the optical radiation source in a hair flow direction.
  • the hair styling device may comprise, along a direction in which the hair is guided, a first sensor, a first LED unit being controlled in dependence on a signal from the first sensor, a second sensor, and a second LED unit being controlled in dependence on a signal from the second sensor.
  • the direction in which hair is guided through the hair styling device may determine which part of the optical radiation source will act as the first LED unit.
  • the hair styling device may comprise a drive mechanism to move the hair along the optical radiation source at a speed controlled by the feedforward control device in dependence on the signal from the sensor unit.
  • Figs. 1-5 illustrate various embodiments of the invention.
  • Hair damage particularly due to the application of heat, is the biggest concern of consumers. Temperature is a major cause of damage done to the hair. It is therefore highly desired to style hair (hair crimping, curling, perming and straightening) without abundant heat. Abundant heat: a hair temperature higher than 180 °C at a certain treatment time (depending on hair characteristics).
  • Applicant's earlier application EP3216368 describes a photo-thermal hair reshaping, e.g. styling, curling, straightening, by using pulse-driven light emitting diodes (LEDs).
  • LEDs pulse-driven light emitting diodes
  • An embodiment may include an optical feedback system e.g. LED light sensor, positioned in the inner surface of a sliding optical shield or in line with the array of LEDs, to sense light, e.g.
  • a certain range of wavelengths preferably between 400 and 900 nm and more preferably between 400 and 550 nm
  • a short period of time preferably shorter than 300 ms.
  • the LED hair styler regulates the current (amount and time) through the LED regardless of variations in power supply or changes in forward voltage. This driver also ensures that the current does not exceed the maximum current rating of the LED.
  • the hair After the release of a predefined light pulse the hair heats to a certain temperature. The temperature increase depends among others by the absorption rate of the hair. The absorption rate of the hair is on its turn determined by the hair characteristics: color, shape, thickness, melanin content, .... Large variations in hair characteristics can be found.
  • bleached hair has no melanin (a major chromophore contributing to photo-thermal hair reshaping), which makes it challenging to use photo-thermal hair reshaping.
  • blond hair needs a considerably higher light density (J/cm 2 ) than brown hair to heat the hair to a comparable temperature.
  • hair will get thinner because of external factors e.g. chemicals, UV, brushing, etc.
  • the hair characteristics will change during lifetime. For instance, the hair diameter and the chromophore concentrations can change along the hair. From top to tip, the hair diameter may decrease.
  • Embodiments of the invention thus show one or more of the following features: during heating the hair by light irradiation, a feedforward loop is in control of the hair properties to overcome overexposure, and during or in-between light exposure (heating of the hairs) the hair properties are measured by one or more sensors before and/or within the treatment area.
  • multiple sensor locations can be used, as shown in Figs. 5a and 5B , e.g. in a checkerboard configuration as shown in Fig. 5a .
  • LEDs Apart from emitting light when a current is applied to a LED, LEDs also have the property that they generate a current when light is applied to the LED when the LED is not used as a light source. So, if light is absorbed by the diode: an inverse current is generated. So, LEDs that are momentarily not used, can be used as light sensors.
  • a first aspect of the invention to mitigate light-induced heat damage to the hair provides a feedforward control using a double flash, i.e. a double light pulse within a short time interval ( ⁇ 200 ms) with the same light source.
  • the first pulse has a relatively low light intensity, and its reflection spectrum is measured with photoelectric sensors and/or the hair temperature is measured with an IR sensor.
  • the sequential second pulse is adjusted to the reflectance rate of the first pulse (transfer function) and is used to photo-thermally heat the hair for reshaping. In this order each second light pulse will heat the hair without running the risk of over-treating the hair.
  • the first light flash is used to measure the status and the characteristics of the hair. Its intensity is between 0.5 and 7 J/cm 2 , preferably between 0.5 and 2 J/cm 2 .
  • the reflection signal of the hair By the reflection signal of the hair, one can make an estimate about the hair color and thickness. From the signal of the IR sensor one can derive the current hair temperature.
  • the sequential second light pulse (intensity > 2 J/cm 2 ) is adjusted accordingly to the information retrieved from the first light flash.
  • both light flashes are produced by the same LEDs. Because the measurement area and treatment area are at the same location, the system will work independent from the direction the hair is guided through the styler.
  • Embodiments of this first aspect have one or more of the following features:
  • the (same) light source in the hair care device is used for detection as well as for treatment.
  • the hair properties of the hair are measured via a low(er) light exposure (flash 1).
  • flash 1 low(er) light exposure
  • flash 1 a feedforward loop
  • the gathered information from flash 1 reflection, absorption, etc.
  • a sequential second light exposure is calculated (timing and intensity) and delivered to the hair.
  • the system response time is within milliseconds (not noticeable to consumer).
  • a second aspect of the invention to mitigate light-induced heat damage to the hair provides sensing and treatment for a feed forward control.
  • the direction of the hair bundle through the styler is fixed (e.g. as in an auto-curler, like the Philips HPS940), the system can be separated in two sections.
  • the first section serves to determine the optical characteristics of the bundle of hair.
  • the bundle is exposed to a light source with a considerably lower intensity, but it has the same optical characteristics as the light source at the second section for heating and shaping the hairs.
  • Its reflection spectrum is measured with photoelectric sensors and/or the hair temperature is measured with an IR sensor.
  • the information derived from the reflection spectrum and/or the temperature sensor is a direct link to the optical behavior of that particular section of the hair tress exposed to that particular wavelength spectrum. In that way the relation between light intensity and increase in hair temperature for that particular part can be determined and be fed forward to the section in the hair where hair shaping takes place.
  • the second section serves to shape the hair by the described light exposing method. Because the speed of the hair tress in the system is known, also the optical characteristics, determined in the first section, of the tress passing this section are known. By continuously adapting the light intensity of the second section according the calculated values based on the previously determined characteristics, the temperature of the hair can be set to the desired.
  • a preferred execution provides a continuous flow of the hair through the system, but of course the method can also be applied to solutions, in which hair is stopped, exposed and measured in the first section, transported to the second session and exposed again with the final intensity.
  • the same control principle can be used, in which case the active area is preferably separated into three sections.
  • the central section is the treatment section.
  • the outer sections are the measurement sections.
  • the measurement sections contain at least a temperature sensor to determine the direction the hair is fed through the system, as the entrance temperature of a hair bundle is lower than the exit temperature.
  • the feed forward principle is equal to the described method with the first and second section.
  • Embodiments of this second aspect of the invention show one or more of the following features: Measuring the optical hair properties prior to treatment.
  • the sensor section has the same optical characteristics as the treatment section.
  • the light emitting treatment area is divided into more than one section, e.g. by wiring the light sources in clusters.
  • a first light treatment area section is set to a certain intensity while the hair temperature is continuously measured. If the hair temperature exceeds a certain level, the light intensity of the next light emitting treatment area section can be lowered. Or vice versa. This way the speed of the treatment does not have to be adjusted. Differences between the hair (e.g. as regards volume, thickness, color, alignment, etc.) are dealt with by means of different light intensity patterns. This method is suitable for devices with single or dual directional hair transport.
  • the entrance part of the hair in the device is known.
  • the sensors simply need to determine the increase in hair temperature after each treatment area and calculate the intensity for subsequent section.
  • the direction of the hair bundle through the system is not known.
  • the direction of the hair bundle can be determined as the entrance temperature of a hair bundle is lower than the exit temperature.
  • controlling the intensity of separate areas is equal to the method of the single directional solution.
  • Another solution is tuning of the speed (hair intake) of the haircare device.
  • differences between the hairs e.g. as regards volume, thickness, color, alignment, etc.
  • the exposure time for thin black hair will be shorter ( ⁇ 5 s) than for thick blond hair.
  • tuning the light intensity one can also think of varying the exposure timing by adjusting the hair intake speed. This way the light intensity remains the same however the light exposure time is adjusted.
  • This method is particularly useful when the hair bundle is automatically transported through the styler (e.g. as in an auto-curler). As a side effect the overall treatment time of each hair strand will vary (e.g. between 0 and 20 s).
  • Embodiments of this third aspect show one or more of the following features: A first part of the light emitting treatment area (perpendicular to the hair input) is used for detection, and a next part of the same light emitting treatment area is used for treatment. Or vice versa. Furthermore, the treatment area can be gradually divided into multiple sections up to the amount of light sources perpendicular to the hair input. For example, the light emitting treatment area can be divided into 4 sensor sections alternated with 4 treatment sections. Starting with a sensor part or starting with a treatment part. This latter feature may be based on an LED checkerboard configuration as shown in Fig. 5a .
  • Fig. 1A shows a first embodiment of the invention, in a hair curler example.
  • Hair H is wrapped around a cylinder C.
  • the hair H is irradiated by an LED unit L, while a sensor S measures effects of the radiation.
  • the sensor signal is processed by a feedforward controller (not shown) that control the LED unit L.
  • Fig. 1B shows an alternative embodiment, in which the cylinder C is heated to a temperature somewhat less than 100 °C, preferably to a temperature between 70 °C and 90 °C.
  • a heat sink of the LED unit 21 is thermally connected to a heat bridge 22. While LEDs are known to be very energy efficient, e.g. for blue light, using the most energy-efficient LEDs, about 50% of the electrical input will become optical energy. While this is great compared to other light sources, it still means that the other 50% of the input energy becomes waste (heat), and needs to be drained.
  • the LED unit 21 is positioned such that hair H is first exposed to heat from the heat bridge 22 and the cylinder C.
  • the hair H is pre-heated by the heat bridge 22 and by the cylinder C, less optical energy from the LED unit 21 is needed to heat the heat to a temperature sufficiently hot for hair styling.
  • the LED unit 21's waste heat is thus advantageously used, as set out in more detail in co-pending application EP17190265.3 .
  • Fig. 2 shows a second embodiment of the invention, again in a hair curler example.
  • the Fig. 2 embodiment differs from the Fig. 1 embodiment in that multiple LED units L1, L2 and multiple sensors S1, S2 are present. In this way, multiple sensors S1, S2 are used to better control the heating of the hair. Also, reflective areas R1, R2 are present so that no light energy is wasted.
  • Figs. 3a and 3b show a third embodiment of the invention, viz. a straightener having a housing Hs.
  • Fig. 3a illustrates the use case that hair H is guided from left to right
  • Fig. 3b illustrates the opposite use case, e.g. when the straightener is used at the other side of a user's head.
  • a first LED unit L1 provides a first flash at a reduced intensity, and based on the measurement by the sensors S1, S2, the intensity of the second LED unit L2 is controlled.
  • the leftmost LED unit is the first LED unit L1
  • the rightmost LED unit is the first LED unit L1.
  • the rightmost LED unit (the one that acts as the first LED unit L1 in the use case of Fig. 3b ) can be controlled together with the second LED unit L2.
  • the leftmost LED unit (the one that acts as the first LED unit L1 in the use case of Fig. 3a ) can be controlled together with the second LED unit L2.
  • Mirrors are preferably present below the hair H to re-use light that has not yet been absorbed.
  • Fig. 4 shows a fourth embodiment of the invention, in which a drive mechanism D regulates the speed of the hair H along the LED unit L and the reflective area R.
  • the drive mechanism D is controlled by the feedforward controller in dependence on a signal from the sensor S.
  • Figs. 5a and 5b show advantageous layouts of LEDs 21 in upper and lower light units of a hair styling device 20, in a zone between parts of a heat bridge 22 connected to heat sinks of the LEDs 21. Between the LEDs 21 shown by means of black squares / stripes, sensors are present in the white squares / stripes. The positions of the LEDs and sensors in the upper and lower light units of the hair styling device 20 are in anti-phase, so that a LED is facing a sensor.
