[embodiment]

A kind of light-emitting device comprises: a projector and a Control Component.Projector has a light source with throw light, and light source can comprise projecting subassembly.Control Component makes the light of projecting subassembly projection can be a projection ray or an illuminating ray in order to the projecting subassembly of control projector.Controlling light when Control Component is a projection ray, and projector is in order to the projection image.Wherein when Control Component control light be an illuminating ray, projector is in order to as illumination light.

First embodiment

Please refer to Figure 1A, Figure 1A illustrates the light-emitting device stereographic map of the 1st embodiment.Light-emitting device 100 comprises a projector 101, a Control Component 103 and an adjustment rack 105.Please refer to Figure 1B, Figure 1B illustrates the projector architecture synoptic diagram.Projector 101 for example is liquid crystal projector or penetration projector.Projector 101 comprises a projecting subassembly 107, a colour disk 109 (Color wheel), one first catoptron 111, one second catoptron 113, one the 3rd catoptron 115, lens 117, a digital micro-mirror device 119 (DMD) and a camera lens 121.The high directivity light that produces with projecting subassembly 107 is as projection ray, earlier via 111 reflections of first catoptron, then produce color (red, green and blue) by colour disk 109 beam split, projection ray again via second catoptron, 113 leaded lights to lens 117 optically focused, then projection ray adjusts the light and shade of light by the 3rd catoptron 115 leaded lights to DMD, at last by camera lens 121 amplification imagings on screen.We can utilize Control Component 103 for example to can be wired or or the wireless controller control direction of adjusting first catoptron 111 be illuminating ray to adjust projection ray.In the present embodiment, first catoptron 111 has the function of optically focused, utilizes the position of control first catoptron 111 and the light path of direction adjustable light bright dipping.

Please be simultaneously with reference to Figure 1B and Fig. 1 C, Fig. 1 C illustrates the structural representation of postrotational first catoptron and projector.Utilize the direction that changes first catoptron 111, light can be by original light path bright dipping to camera lens 121, and directly bright dipping and can cooperate the mixed light sheet 123 (as cloudy surface eyeglass) of utilization shown in Fig. 1 C to make the light of the high directivity of projecting subassembly 107 become the light of low directive property, and with the light of low directive property as illuminating ray.

Please refer to Fig. 1 D and Fig. 1 E.The light that Fig. 1 D illustrates projector penetrates synoptic diagram by camera lens.The projecting subassembly 107 that Fig. 1 E illustrates projector penetrates synoptic diagram by side.In user's desire with light-emitting device 100 during as projector's 101 purposes, by changing the sense of rotation of first catoptron 111, whole light that first projection light source 107 is launched just can be by camera lens 121 direct bright dippings, and carry out bright dipping shown in Fig. 1 E by the side of projector.Certainly also can change other catoptron sense of rotation,, also can make light change path and can't help the camera lens bright dipping as second catoptron or the 3rd catoptron.

Please refer to Fig. 2 A, Fig. 2 A illustrates light-emitting device side diagrammatic sketch.In adjustment rack 105, have pedestal 131, carrier 133 and adjustment part 135.And the hinge portion 137 that has in the projector 101 couples carrier 133, and the weight of projector 101 is sent to pedestal 131 via hinge portion 137, carrier 133 and adjustment part 135.

Please be simultaneously with reference to Fig. 2 A and Fig. 2 B, Fig. 2 B illustrates projector's rotation synoptic diagram.See through the hinge portion 137 that is disposed at projector 101 bottoms, projector 101 can 137 rotations around the hinge portion.Simultaneously, height can be adjusted according to user's height and hobby in adjustment part 135.Adjustment part 135 for example can be rotary or push type, and carrier 133 1 ends couple the hinge portion 137 of projector 101, and the other end is embedded in the pedestal 131 by adjustment part 135.On the other hand, have several thermovent 139 neighbor configuration in projector 101 bottoms, reducing the temperature of projector 101, to avoid too high and the electronic package that infringement is inner of projector's 101 temperature in projecting subassembly 107.

Second embodiment

Please refer to Fig. 3, Fig. 3 illustrates the light-emitting device vertical view of second embodiment.Different with first embodiment is, utilizes configuration projecting subassembly 107 and luminescence component 307 to form light sources in a second embodiment.Projecting subassembly 107 and luminescence component 307 are to can be various luminescence components, for example projecting subassembly 107 can be light emitting diode, Halogen lamp LED, metal halide lamp (Metal Halide), ultrahigh pressure mercury lamp (UHP/UHE) or xenon lamp (Xenon arc), and light fixture 307 can be general illumination lamp source such as light emitting diode, incandescent lamp, gas-discharge lamp (Discharge lamp) etc.Projecting subassembly produces the high projection ray that points to, and luminescence component produces the low illuminating ray that points to.Control Component can be luminous by projecting subassembly 107 or luminescence component 307 by control, decides the function of light-emitting device as illumination or projection projection.For example with Control Component control when projecting subassembly 107 emits beam, luminescence component 307 is to close, the projection ray of the height sensing that projecting subassembly 107 is sent can be used as the light of projector's projection.If open light fixture 307, and close projecting subassembly 107, this moment, light fixture 307 can send the low even light that points to and around being dissipated into, and became illuminating ray.And can cooperate adjustment rack 105, and adjust the height of projector 101 so that the user can be according to hobby and height adjustment height, and collocation hinge portion 137, whether adjust upwards projection of image, user even can look at ceiling and see a film with light or projection.

The disclosed light-emitting device of the above embodiment of the present invention, in first embodiment, the direction by changing reflector plate is so that single light source is reached the function of switching illumination and projector.And in a second embodiment, utilizing increases another luminescence component, makes two different luminescence components do switching, respectively the light source of conduct illumination and projection.Can utilize simultaneously adjustment rack to adjust the height of projector, make the user can control the position of projector's projection, and then increase delight of life according to hobby height, and the surcharge of product.

In sum; though the present invention discloses as above with a preferred embodiment; right its is not in order to limit the present invention; anyly have the knack of this skill person; without departing from the spirit and scope of the present invention; when can being used for a variety of modifications and variations, so protection scope of the present invention is as the criterion when looking accompanying the claim person of defining.
