Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
The first embodiment is as follows:
referring to fig. 1-2, an LED color lamp for building decoration comprises a lamp strip 1 and a lamp housing 2 mounted on the lamp strip 1, LED color lamp beads 3 are mounted in the lamp housing 2, a square cavity 4 is formed in the side wall of the lamp housing 2, and an arc-shaped cover 5 is fixedly connected to the bottom of the square cavity 4.
It should be noted that the lower end of the arc cover 5 is in close contact with the bottom of the square cavity 4, and the square cavity 4 is divided into two cavities which are not communicated with each other, so that the arc cover 5 can deform under the action of air pressure.
The arc-shaped cover 5 is made of piezoelectric ceramic materials, and two ends of the arc-shaped cover 5 are connected in series in a power supply circuit of the LED colored lamp beads 3 through capacitors, it should be noted that the connection mode between the arc-shaped cover 5 and the capacitors and the LED colored lamp beads 3 is a common technical means in the existing power field, and is irrelevant to the design purpose of the scheme, so detailed description is omitted.
The lateral wall of lamp body 2 has been seted up ventilation hole 6, and through negative pressure hole 41 intercommunication between ventilation hole 6 and the square chamber 4, and the circular recess 7 of ventilation hole 6 intercommunication is seted up to the lateral wall of lamp body 2, installs the speed change gear of wind speed in the drop cloth ventilation hole 6 in the circular recess 7.
Speed change gear is including rotating the carousel 8 of connecting in circular slot 7, and a plurality of not equidimension air holes 81 have been seted up to the lateral wall of carousel 8, and the axle center of a plurality of air holes 81 is located same graduated circle, the coaxial fixedly connected with wind wheel 9 of the lateral wall of carousel 8, the flabellum and the air hole 81 dislocation set of wind wheel 9. It should be noted that, by arranging the blades of the wind wheel 9 and the air holes 81 in a staggered manner, the blades can be prevented from interfering with the air flow, and further the use effect of the device is affected. Further, of the plurality of air holes 81 having different sizes, the largest air hole 81 is smaller than the hole diameter of the vent hole 6.
In order to improve the decoration effect of building, the LED colored lamps are often installed outside the building, and outdoor air flows frequently. When wind blows the wind wheel 9, can make the wind wheel 9 and rotate together with the coaxial fixed carousel 8 of wind wheel 9, when carousel 8 rotated, not equidimension gas pocket 81 will communicate with ventilation hole 6 on the carousel 8, can make the total amount of air through ventilation hole 6 constantly change thereupon in the unit interval, and the air velocity through in the ventilation hole 6 constantly changes along with the rotation of carousel 8 promptly.
When air flows in the vent hole 6, the air in the vent hole 6 flows fast and has low pressure, and the air in the square cavity 4 hardly flows and has high pressure, so that pressure difference can be generated in the negative pressure hole 41 communicating the air and the negative pressure hole, partial air below the arc cover 5 in the square cavity 4 is forced to flow into the vent hole 6, and the arc cover 5 is sunken downwards. And the air flow rate in the vent hole 6 is continuously changed along with the rotation of the rotary disc 8, and the pressure difference between the vent hole 6 and the square cavity 4 is also continuously changed.
When the air flow in the vent hole 6 is fast, the pressure difference between the two is large, and the downward sunken part of the arc cover 5 is more; when the air flow in the vent hole 6 is slow, the pressure difference between the two is small, and the downward concave part of the arc cover 5 is small. So can arouse arc cover 5 constantly to vibrate, can make the arc cover 5 that is made by piezoceramics produce the electric current, and transmit for LED color lamp pearl 3 through electric capacity, make the electric current size through in the LED color lamp pearl 3 constantly change thereupon together, finally arouse LED color lamp pearl 3 to send the bright and dark change light and awn of scintillation, change with replacing traditional electron program control light, it is energy-concerving and environment-protective more, need not to install numerous and diverse electronic equipment simultaneously, the construction degree of difficulty is low, it can only to need to overhaul lamps and lanterns also when overhauing. In addition, the electric energy generated by the arc-shaped cover 5 can be used for the LED colored lamp beads 3 to emit light, so that the electric power initially supplied to the lamp body can be set to be lower, and the electric energy loss is further saved.
Example two:
referring to fig. 3, the difference from the first embodiment is that the square cavity 4 is filled with the cooling liquid, the cooling liquid is only located on the upper side of the arc-shaped cover 5, the liquid guide tube 10 is embedded in the lamp housing 2, the liquid guide tube 10 is arranged around the LED colored lamp bead 3, the water inlet end and the water outlet end of the liquid guide tube 10 are both communicated with the inside of the square cavity 4, and the first check valve 101 and the second check valve 102 are respectively installed in the water inlet end and the water outlet end of the liquid guide tube 10.
It should be noted that the first one-way valve 101 only allows the cooling fluid to flow from the square lumen 4 into the catheter 10, and the second one-way valve 102 only allows the cooling fluid to flow from the catheter 10 into the square lumen 4.
Further, the coolant liquid in the square cavity 4 can transmit to the arc cover 5 after having absorbed the heat that LED color lamp pearl 3 gived off, and the below air flow of arc cover 5 is frequent, again with the direct contact of arc cover 5, can give off the heat fast to 2 outsides of lamp body, therefore this device radiating effect is very good.
In this embodiment, the arc cover 5 can dissipate heat from the LED color lamp bead 3 in the up-and-down vibration process. The specific working process comprises the following steps: when the arc cover 5 bulges upwards, the cooling liquid above the arc cover 5 can be squeezed into the liquid guide pipe 10 through the first one-way valve 101, and when the arc cover 5 sinks downwards, the cooling liquid in the liquid guide pipe 10 can be pumped into the square cavity 4 through the second one-way valve 102. So can be at the upper and lower vibration in-process of arc cover 5, force the coolant liquid at catheter 10 inner loop flow to the quick heat with the production of LED color lamp pearl 3 distributes away fast, makes LED color lamp pearl 3 keep lower temperature state, avoids high temperature to cause the harm to LED color lamp pearl 3, prolongs the life of equipment.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
