Embodiment
Projector of the present invention mainly improves the structure that is bulb cooling device, in order to make icon more cheer and bright, Figure 1A to Fig. 7 mainly illustrates the structure of bulb cooling device, does not show the housing overall picture (shown in Figure 1A) of projector, only illustrates a part of housing as an illustration.In addition, projector is placed on the supporting plane P1, and can rotate an angle [alpha] relative to supporting plane, to change projection angle.
See also Fig. 2 A and Fig. 2 B.The projector 3 that Fig. 2 A illustrates according to first embodiment of the invention is rotated preceding synoptic diagram.Fig. 2 B illustrates the front elevation of the projector 3 among Fig. 2 A.Shown in Fig. 2 A and Fig. 2 B, projector 3 comprises housing 30, bulb 32, lampshade 34, wind-guiding module 35 and fan 36.Wind-guiding module 35 comprises first air guide member 350, second air guide member 352 and web member 354.Air intake vent 340 and air outlet 342 are formed between first air guide member 350 and second air guide member 352.First air guide member 350 sees through web member 354 and is connected in second air guide member 352, but makes air guide member 350 interlocks of winning in second air guide member 354.Fan 36 is fixed on the housing 30, and is blown into air-flow in lampshade 34, with cooling bulb 32.
When the bulb 32 among Fig. 2 A and Fig. 2 B was luminous, the surface of bulb 32 had focus (hot spot) H, no matter the rotational angle of bulb 32 why, must be parallel to gravity direction G1 by focus H to the direction at the center of bulb 32.In addition, because the optical axis of the light that bulb 32 is launched and the optical axis of the light that projector 3 is throwed are mutually perpendicular (consulting opticpath shown in Figure 1), therefore when projector 3 is enhanced projection angle (shown in Fig. 3 A and Fig. 3 B), bulb 32, lampshade 34, wind-guiding module 35 and fan 36 all can rotate an angle [alpha] relative to supporting plane P1.The influence of the 3 pairs of air flow directions of projector after the rotation and the structure of wind-guiding module 35 see also Fig. 3 A to Fig. 4 B to the influence of air flow direction.Fig. 3 A illustrates the synoptic diagram after projector 3 is rotated among Fig. 2 A.Fig. 3 B illustrates the front elevation of the projector 3 among Fig. 3 A.Fig. 4 A illustrates the synoptic diagram of wind-guiding module 35 rotations one angle of Fig. 3 A.Figure four B illustrate the front elevation of the projector 3 among figure four A.
Shown in Fig. 2 A to Fig. 4 B, wind-guiding module 35 is arranged in the lampshade 34 movably, optionally to be positioned at the primary importance and the second place.The position of wind-guiding module 35 can be defined as the rotational angle of wind-guiding module 35 relative lampshades 34.In addition supplementary notes is, can utilize one a slide rail/chute structure or a bearing arrangement to be connected between wind-guiding module 35 and the lampshade 34, allows wind-guiding module 35 lampshade 34 activities relatively.In this embodiment, this activity refers to wind-guiding module 35 and rotates relative to the axis of symmetry A1 of bulb 32.
As Fig. 3 A and Fig. 3 B as can be known, because projector 3 changes projection angle and rotates an angle [alpha] relative to supporting plane P1, and the hot zone of bulb is roughly parallel to gravity direction G1, so the hot zone of bulb 32 is changed to focus H ' from focus H, folder one angle [alpha] between focus H and the focus H '.Shown in Fig. 3 A and Fig. 3 B, when wind-guiding module 35 was positioned at primary importance, air-flow flowed into air intake vent 340 with first direction D1, and blowed to bulb 32 with first direction D1, and then air-flow is flowed out by air outlet 342 again.Shown in Fig. 4 A and Fig. 4 B, when being positioned at the second place after wind-guiding module 35 rotations one angle [alpha], the air-flow that first air guide member 350 and second air guide member 352 will blow to bulb jointly is the second direction D2 that differs from first direction D1 from first direction D1 (shown in Fig. 3 B) guiding, makes air-flow to flow to the best and blow to bulb 32 to take away heat.In this embodiment, second direction D2 is in fact perpendicular to gravity direction G1, but the invention is not restricted to this.
Shown in Fig. 4 A and Fig. 4 B, first air guide member 350 comprises first plane, 3500, the second air guide members 352 and comprises the first surface 3524 that is adjacent to air intake vent 340.First plane 3500 and first surface 3524 form the first crooked air channel, and the first crooked air channel roughly is L shaped, and air intake vent 340 is near an end in the first crooked air channel.After air-flow flows into the first crooked air channel by air intake vent 340, at first stopped and flow, then stopped and flow along first plane 3500 by first plane 3500 of first air guide member 350 along first surface 3524 by the first surface 3524 of second air guide member 352.Because first plane 3500 is perpendicular to gravity direction G1, therefore can flatly blow to bulb (that is blow to bulb with second direction D2) along first plane, 3500 airflow flowing.Moreover second air guide member 352 comprises second plane 3520, and is parallel to first plane 3500 in fact.Second plane 3520 can further stop the air-flow that rebounds from first plane 3500, and forces the air-flow of bounce-back to flow along second direction D2, and then the horizontal flow of strengthening flow, to reach preferable cooling effect.
