Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail.
See also Fig. 1, the embodiment of the invention provides a kind of light-emitting diode 10.This light-emitting diode 10 comprises a substrate 102, luminescence chip 104, packaging body 106, a liquid lens group 108 and an operating circuit.
This packaging body 106 comprises a plurality of sidewalls 136,138 and upper and lower two transparent glass plates 140.The substrate 102 of this light-emitting diode 10 can be made by the good material of heat dispersion, as aluminium, and aluminium alloy, copper or copper alloy are used to carry luminescence chip 104 and provide better heat radiating effect for luminescence chip 104.This luminescence chip 104 can be selected from any of red light-emitting chip, green luminescence chip and blue light emitting chip. Liquid lens group 108 and 104 of luminescence chips can add be doped with coupling fluorescent material transparent resin (figure does not show) so that this light-emitting diode 10 sends white light.For example, if this luminescence chip 104 is blue light emitting chips, then the fluorescent material of Jia Ruing is red green mixed fluorescent powder, the blue-light excited red green mixed fluorescent powder that the blue light emitting chip sends, make fluorescent material produce ruddiness and green glow, the blue light of sending with original blue light emitting chip is to produce white light again.This luminescence chip 104 can pass substrate 102 and connects with substrate 102 insulation electrodes in contact lead-in wire 112 and external power (figure does not show) by two.
It is pointed out that this light-emitting diode 10 also can be arranged at red light-emitting chip, green luminescence chip and blue light emitting chip formation multicolour light source in the substrate simultaneously.
This liquid lens group 108 is arranged in luminescence chip 104 bright dipping light paths, and the thickness of this liquid lens group 108 is greater than 0 millimeter, smaller or equal to 10 millimeters.This liquid lens group 108 comprises that one is gone up liquid lens 114 and a following liquid lens 116, and liquid lens 114 contacts with liquid lens 116 and forms a contact-making surface 200 on this.Should go up liquid lens 114 and be made up of deformable first transparent encapsulating body 118 and first liquid 120 that are sealed in first transparent encapsulating body 118, this time liquid lens 116 is by deformable second transparent encapsulating body 122 and be sealed in second transparent encapsulating body, the 122 second interior liquid 124 and form.This first transparent encapsulating body 118 and second transparent encapsulating body 122 can be made by identical or different materials.The plastics of this material selection printing opacity and high ductibility or the material of rubber film.In the present embodiment, this first liquid 120 is water, and this second liquid 124 is optical match oil.
This operating circuit makes the contact-making surface 200 of 116 of liquid lens 114 and following liquid lens that alterations of form take place and makes this liquid lens group 108 realize zooms.This operating circuit comprises ring electrode 126, middle ring electrode 128 respectively, following ring electrode 130, a ZSW 132 and a forward voltage source 134.
This time, in, to go up ring electrode 126,128,130 can be transparent tin indium oxide (ITO) electrode or metal electrode.In the bright dipping light path of luminescence chip 104, this time, in, go up ring electrode 126,128,130 and be arranged in order respectively, and upper and lower ring electrode 126,130 is separately fixed at the two ends of liquid lens group 108 and it is inconsistent with the outer rim of last liquid lens 114 to go up ring electrode 126, and following ring electrode 130 is inconsistent with the outer rim of following liquid lens 116.Should in ring electrode 128 last liquid lens 114 and down between the liquid lens 116 and can make progress liquid lens 114 directions or following liquid lens 116 directions move.Certainly, moving of ring electrode 128 can as slideway (scheming not show) is set in packaging body 106 sidewalls 138, is arranged at ring electrode 128 outer rims and waits realization in the slideway by various means of the prior art in the realization.Should pass through lead ground connection by middle ring electrode 128.
This ZSW 132 is provided with two gear A, B, when ZSW pushes gear A, can connect with forward voltage source 134 going up ring electrode 126; When ZSW pushes gear B, can will descend ring electrode 130 and forward voltage source 134 to connect.
