Definitions

  • the present invention relates to the field of lighting, and in particular to a light-emitting device and a surgical lamp using the light-emitting device.
  • Surgical lamps as special lamps used in an operating room, need to achieve a shadowless effect in addition to meeting the requirements of brightness. Therefore, the surgical lamp is generally large in size, and the size of a lamp head may reach 600-700 mm, and a plurality of light beams converge into a desired light spot to illuminate a surgical fields of surgical operation.
  • a commonly used surgical lamp generally adopts the technical solution of Gypsophila.
  • an LED light source is placed in a reflective shade or lens to form a separate lighting unit.
  • a plurality of lighting units are distributed inside the lamp head and their irradiation directions are directed to a surgical region, and finally an area light source with a certain direction and converging light rays is formed to achieve a shadowless effect.
  • the method of changing the irradiation angle of the lighting unit to change the light intensity distribution of the surgical region or the method of changing the relative intensity of light rays output by the lighting unit that are irradiated at different positions in the surgical region to change the light intensity distribution of the surgical region, is generally used.
  • Gypsophila Another variant of the solution of Gypsophila is to distribute the plurality of above-mentioned lighting units composed of LED light sources and lenses to the periphery of the lamp head, a large reflective shade is placed in the middle of the lamp head, and the light rays emitted by these lighting units are directly or indirectly directed towards the center of the lamp head and are irradiated on the reflective shade, which in turn reflects the light rays to the surgical region.
  • the method of changing the size of the light spot in the surgical region is to use two groups (or more groups) of lighting units, and the positions and irradiation angles of multiple groups of lighting units in the lamp head are different, so that the directions of the light rays after reflected by the reflective shade are also different, forming different light intensity distributions in the surgical region, and the light intensity distribution of the surgical region is changed by changing the relative intensity of output of the two groups of lighting units.
  • US 2012/051063 A1 discloses an apparatus that includes a light source, a first reflector, a lens and a second reflector.
  • the first reflector is positioned to reflect a first portion of light from the light source, wherein the first portion of light is radiated from the light source in a central forward solid angle as defined by an outer edge of the first reflector.

  • an embodiment further provides a surgical lamp using the light-emitting device described above.
  • a lateral light beam emitted by the light source is collected by a profiled optical element that causes light rays to deflect in varying degrees, thereby changing an exit direction of the light beam to cause the light beam to be directed towards the reflective shade disposed on the periphery, then the reflective shade mixes and reflects the light beam, and finally the light rays at different positions of the reflective shade are superimposed at a desired position (e.g. the surgical region) and form a desired light spot.
  • the surgical lamp made by using the light-emitting device of the present invention may increase the light-emitting area of the entire surgical lamp by making larger the transverse dimension of the reflective shade, thereby avoiding a shadow zone caused by obstruction of an object (such as a doctor's head) under the surgical lamp, and thus achieving a good shadowless effect.
  • connection or “couple”, unless otherwise specified, includes both direct and indirect connections (coupling).
  • the light-emitting device disclosed in an example of the present invention no longer adopts the solution of Gypsophila composed of a plurality of small lighting units, but one or more light sources share an optical system, which collects light emitted by the light source, and after reflection, the light will converge into a desired light spot.

Since the optical axis of the light source deviates from the central axis, at this time the light rays cannot be completely converged by the reflective shade, a large light spot is formed in the surgical region. As shown in Fig. 6 , the light rays emitted by the peripheral light source 7 that is off-center are deflected by the light deflection element 2 and then produce light rays in different directions, said light rays are no longer horizontal with respect to the light rays in Fig.
