Abstract

In some aspects, a fan with lighting effect includes a fan blade assembly, a fan frame, a light emitting module, a reflector and a light guide. The fan frame has a periphery structure radially disposed to surround the fan blade assembly, the periphery structure having an inner wall and an outer wall defining a slot therebetween. The light emitting module is disposed in the slot and oriented to emit light along a light path non-parallel with the rotational axis of the fan blade. The reflector is disposed in the slot and in the light path of the light emitting module for reflecting the light emitted by the light emitting module. The light guide is fitted to the slot in a manner to guide light to exit from the slot via the slot opening.

Claims (19)

  1. 1 . A fan with lighting effect, comprising: a fan blade assembly having a plurality of fan blades rotatable about a rotational axis of the fan blade assembly; a fan frame having a periphery structure radially disposed from the rotational axis to surround the fan blade assembly, the periphery structure having an inner wall and an outer wall defining a slot therebetween, the outer wall being radially farther than the inner wall with respect to the rotational axis, wherein an edge of the inner wall and a corresponding edge of the outer wall defines a slot opening; a light emitting module disposed in the slot and oriented to emit light along a light path non-parallel with the rotational axis of the fan blade; a reflector disposed in the slot and in the light path of the light emitting module for reflecting the light emitted by the light emitting module; and a light guide fitted to the slot in a manner to guide light to exit from the slot via the slot opening, wherein the light guide abuts an edge of the reflector and an edge of the light emitting module, respectively.
  2. 2 . The fan of claim 1 , wherein an opposite edge of the inner wall and a corresponding opposite edge of the outer wall defines a further slot opening.
  3. 3 . The fan of claim 2 , comprising a further light guide fitted to the slot in a manner to guide light to exit from the slot via the further slot opening.
  4. 4 . The fan of claim 3 , wherein the light emitting module and the reflector are between the light guide and the further light guide, and within the slot.
  5. 5 . The fan of claim 4 , wherein the further slot opening lies in a plane substantially perpendicular to the rotational axis of the fan blade assembly.
  6. 6 . The fan of claim 4 , wherein the further light guide is fitted to the slot at the further slot opening in a manner so as to form a flushed surface extending between the opposite edge of the inner wall and the corresponding opposite edge of the outer wall.
  7. 7 . The fan of claim 4 , wherein the further light guide is integrally fitted to the further slot via insert molding.
  8. 8 . The fan of claim 1 , wherein the slot is an annular slot.
  9. 9 . The fan of claim 8 , wherein the light emitting module comprises a light reflective substrate having a ring shape, wherein the light reflector has a corresponding ring shape, wherein the light emitting module and the light reflector are disposed in a manner such that the light reflective substrate and the light reflector are substantially concentric with each other.
  10. 10 . The fan of claim 1 , wherein the inner wall is an annular inner wall and the outer wall is an annular outer wall, wherein the annular inner wall and the annular outer wall are arranged in a substantially concentric manner.
  11. 11 . The fan of claim 1 , wherein the light emitting module and the light reflector are disposed in an opposing manner.
  12. 12 . The fan of claim 1 , wherein the slot opening lies in a plane substantially perpendicular to the rotational axis of the fan blade assembly.
  13. 13 . The fan of claim 1 , wherein the light guide is fitted to the slot at the slot opening in a manner so as to form a flushed surface extending between the edge of the inner wall and the corresponding edge of the outer wall.
  14. 14 . The fan of claim 1 , wherein the light guide comprise a Y-shape cross-sectional profile.
  15. 15 . The fan of claim 14 , wherein two branches of the Y-shaped cross-sectional profile are substantially parallel.
  16. 16 . The fan of claim 14 , wherein a bottom part of the Y-shaped cross-sectional profile is tapered.
  17. 17 . The fan of claim 1 , wherein the fan frame comprises four protrusions uniformly distributed around the periphery structure of the fan frame, each protrusion extending radially outwards with respect to the rotational axis of the fan blade assembly.
  18. 18 . The fan of claim 1 , wherein the light emitting module comprises red, blue and green LEDs.
  19. 19 . The fan of claim 1 , wherein the light guide is integrally fitted to the slot via insert molding.

Description

TECHNICAL FIELD The present disclosure generally relates to a fan, in particular, a fan with lighting effect. BACKGROUND Cooling fans with lighting effect are widely available in the market. However, a cooling fan for electronic devices, for example, a computer, not only has to be functionally effective but also to be attractive in its appearance. Therefore, there exists a need for fans that have improved lighting effect and more appealing aesthetics. SUMMARY According to a first aspect of the present disclosure, a fan with lighting effect is provided. The fan may include a fan blade assembly having a plurality of fan blades rotatable about a rotational axis of the fan blade assembly; a fan frame having a periphery structure radially disposed from the rotational axis to surround the fan blade assembly, the periphery structure having an inner wall and an outer wall defining a slot therebetween, the outer wall being radially farther than the inner wall with respect to the rotational axis, wherein an edge of the inner wall and a corresponding edge of the outer wall defines a slot opening; a light emitting module disposed in the slot and oriented to emit light along a light path non-parallel with the rotational axis of the fan blade; a reflector disposed in the slot and in the light path of the light emitting module for reflecting the light emitted by the light emitting module; and a light guide fitted to the slot in a manner to guide light to exit from the slot via the slot opening.
