Detailed Description
Embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways, which are defined and covered by the claims.
Referring to fig. 1, which is a schematic structural diagram of a solar LED street lamp according to an embodiment, for example, a solar LED street lamp 10 includes: the solar lamp comprises a solar panel 101, a rotating device 102, a lamp post 103, a lamp assembly 104 and a waste recycling device 105. The solar cell panel 101 is disposed on a rotating end of the rotating device 102, a fixed end of the rotating device 102 is disposed at a tail end of the lamp post 103, the lamp assembly 104 is disposed on the lamp post 103, the lamp assembly 104 is adjacent to the rotating device 102, and the waste recycling device 105 is disposed at a bottom end area of the lamp post 103 far away from the rotating device 102.
As shown in fig. 2, the solar cell panel 101 includes a cell assembly 111 and a panel 121, the cell assembly 111 is used for absorbing light energy to generate power, the cell assembly 111 is disposed on the panel 121, and a rotation position 131 is disposed on a side of the panel 121 opposite to the cell assembly 111. It is understood that the cell assembly 111 includes a plurality of cells and a battery pack, and the plurality of cells are arranged in a matrix on the plate body 121. The battery pack is disposed in the plate body 121, and is electrically connected to each battery piece, and the battery pack is used for storing electric energy converted by the plurality of battery pieces for use by the lamp assembly 104. For example, the plate body 121 has a rectangular structure; for another example, the plate body 121 has a circular structure, and for another example, the plate body 121 has an irregular structure. The shape of the plate body 121 can be set according to the specific use environment and the use requirement.
referring to fig. 3, which is a schematic partial structural view of an embodiment of a solar LED street lamp, for example, the rotating device 102 includes a frame 112, a servo motor 122 and a rotating member 132, the frame 112 is fixedly disposed at the end of the lamp post 103, and the servo motor 122 is electrically connected to the battery plate assembly 111, so that the battery plate assembly 111 can supply power to the servo motor 122. For example, a control chip is separately provided in the servo motor 122, and the control chip controls the operation speed and direction of the motor in the servo motor 122. For example, the control chip is a single chip microcomputer. The servo motor 122 is disposed on the frame 112, the rotating member 132 is connected to an output end of the servo motor 122, and the servo motor 122 is configured to drive the rotating member 132 to rotate so that the rotating member 132 rotates along a preset rotating track. The end of the rotating member 132 is fixedly connected to the rotating member 131. For example, the end of the rotating member 132 is riveted to the rotating portion 131.
For example, the output end of the servo motor 122 has a rotation amplitude of 180 degrees, which is a half circle; thus, the preset rotation track is a half circle. For example, the output of the servo motor 122 rotates in a single reciprocating direction, i.e., back and forth in one direction. For example, the operating time of the servo motor 122 is divided into summer time and winter time, that is, summer time and winter time are set in the control chip. For example, in daylight savings, the servo motor 122 is operated during daylight hours, i.e., 6 am to 19 pm, and is stopped during the remaining hours. For another example, in winter season, the operation time of the servo motor 122 is daytime, i.e., from 7 am to 18 pm, and the rest of the time stops. For another example, an included angle is formed between the solar cell panel 101 and the rotating member 132, that is, the solar cell panel 101 is obliquely arranged on the rotating member 132, so that when a user installs the solar LED street lamp, the orientation of the solar cell panel 101 can be adjusted according to the installed longitude and latitude, so that the solar cell panel 101 moves along the amplitude directions of sunrise and sunset, similar to the moving direction of a sunflower, and thus the solar cell panel 101 can absorb more sunlight, and utilize the conversion capability thereof to the maximum extent, and obtain more electric energy.

That is, the annular mounting groove is opened on the lamp post 103, and for example, the lamp post 103 is inwardly recessed by a predetermined depth to form the annular mounting groove. For example, the inner diameter of the annular mounting body 114 is equal to the inner diameter of the annular mounting groove. For example, a plurality of connection sites 1141 are disposed outside the annular mounting body 114, and each heat sink 124 is disposed at a corresponding connection site. That is, the outer side of the annular mounting body 114 is provided with a connection site for connecting the heat sink 124. For example, the connection site is a weld site; in another example, the connection site is an abutment site. For example, the side of the heat dissipation member 124 facing away from the solar panel 101 is provided with a mounting area 106, and each LED wick 134 is correspondingly disposed in the mounting area of one heat dissipation member 124. That is, the mounting area is disposed on the side of the heat sink 124 facing downward toward the ground, so that light emitted from each LED wick 134 is emitted toward the ground.
For example, the heat sink 124 includes a heat sink 144, a two-way memory alloy plate 154 and a plurality of two-way memory alloy strips 164, two through holes 174 are formed at the bottom of the heat sink 144, one side of the two-way memory alloy plate 154 is connected to the top side of the heat sink 144, the LED wick 134 is disposed at the bottom of the heat sink 144 opposite to the two-way memory alloy plate 154 and covers the two through holes 174, and the plurality of two-way memory alloy strips 164 includes two sets of two-way memory alloy strips, each of the two sets of two-way memory alloy strips correspondingly penetrates one through the through hole and is connected to the LED wick. That is, each of the two-way memory alloy strips is correspondingly disposed in a through hole 174, and each of the two-way memory alloy strips correspondingly penetrates through a through hole 174 and is connected to the LED wick 134. Therefore, heat generated by the LED lamp wick 134 can be transferred to the heat dissipation groove 144, the two-way memory alloy strip 164 and the two-way memory alloy plate 154, and then is dissipated to the outside through the heat dissipation groove 144, the two-way memory alloy strip 164 and the two-way memory alloy plate 154, and most of the heat generated on the two-way memory alloy strip 164 can be rapidly dissipated through the two-way memory alloy strip 164 due to the fact that the two-way memory alloy strip 164 is directly contacted with the LED lamp wick 134, and heat dissipation efficiency is high.
for example, the chip circuit board of the LED wick 134 is soldered to the bottom of the heat sink 144 and covers the two through holes 174, for example, the chip circuit board covering the through holes 174 is hermetically connected to the periphery of the through holes 174, so that the through holes 174 form a groove, and the two-way memory alloy strip 164 is soldered directly to the chip circuit board of the LED wick 134, which can improve the heat dissipation efficiency. The chip circuit board of the LED lampwick 134 is electrically connected to the battery piece assembly of the solar cell panel 101 through a cable, and a micro control chip is arranged in the chip circuit board of the LED lampwick 134 to control on and off of the LED lampwick 134, for example, in summer season, the working time of the servo LED lampwick 134 is daytime, i.e., 6 am to 19 pm, and the rest of the time stops working. For another example, in winter, the LED lamp 134 is operated during daytime, i.e., from 7 am to 18 pm, and the rest of the time is stopped. Therefore, unmanned control can be realized, a user only needs to install the solar LED street lamp to a preset road section, the LED lamp core 134 is turned on and off according to a preset program, and manpower investment is saved.
for further improving the heat dissipation efficiency, for example, the heat dissipation groove 144 is covered when the two-way memory alloy plate 154 is cooled, and the two-way memory alloy plate 154 is bent obliquely with respect to the heat dissipation groove 144 when heated. Fig. 4 shows the state of the two-way memory alloy plate 154 against the heat sink 144 when heated. For example, the two-way memory alloy plate is a memory aluminum alloy; for another example, the two-way memory alloy plate is a memory copper alloy; for another example, the two-way memory alloy plate is another memory alloy with good thermal conductivity. For example, the transformation temperature of the two-way memory alloy plate is 70-80 degrees celsius, that is, the two-way memory alloy plate 154 recovers the shape of the high temperature phase when heated to 70-80 degrees celsius, and at this time, the two-way memory alloy plate 154 bends obliquely relative to the heat dissipation groove 144. This means that the two-way memory alloy plate 154 absorbs a large amount of heat from the LED wick 134. Particularly, because the heat dissipation groove 144 is covered by the two-way memory alloy plate 154 when the LED wick 134 is cooled, that is, when the LED wick 134 does not work, the two-way memory alloy plate 154 is in a cooled state, the heat dissipation groove 144 is covered by the two-way memory alloy plate 154 in this state, when the LED wick 134 works, the temperature in the heat dissipation groove 144 rises sharply, the temperature of the two-way memory alloy plate 154 also rises sharply, when the temperature of the two-way memory alloy plate 154 rises to its transformation temperature, the phase transformation occurs in the two-way memory alloy plate 154, the two-way memory alloy plate 154 bends obliquely relative to the heat dissipation groove 144, at this time, the heat dissipation groove 144 is equivalent to an open state, the air flow is accelerated, the heat accumulated in the heat dissipation groove 144 is released to the outside, and the temperatures of the heat dissipation groove 144 and the two-way memory alloy plate 154 also fall correspondingly and maintain balance, so that when the LED wick 134 does not work or the working time is short, the two-way, because the heat dissipation requirement is low at this time, the two-way memory alloy plate 154 can realize the heat dissipation effect without being opened; when the LED wick 134 is in operation or the LED wick 134 is in operation for a long time, the two-way memory alloy plate 154 is bent obliquely relative to the heat dissipation groove 144, because the heat dissipation requirement is large at this time, the LED wick 134 generates a large amount of heat due to the operation, and when the temperature reaches the transformation temperature of the two-way memory alloy plate 154, the two-way memory alloy plate 154 is bent obliquely, so that the heat is released to the outside, and thus, the heat dissipation efficiency can be controlled freely in retraction and release, and the service life of the LED wick 134 is prolonged.
For another example, the area of the two-way memory alloy plate 154 is larger than the opening area of the heat dissipation groove 144, so that when the two-way memory alloy plate 154 is bent obliquely relative to the heat dissipation groove 144, the two-way memory alloy plate 154 blocks the heat dissipation groove 144, thereby preventing rainwater from directly flowing into the heat dissipation groove 144. As another example, the bottom of the heat sink 144 is inclined. For example, the bottom of the heat dissipation groove 144 is inclined outward with respect to the horizontal plane, so that rainwater drifting into the heat dissipation groove 144 can flow out along the inclined plane of the bottom of the heat dissipation groove 144. For another example, the bottom of the heat sink 144 is opened with a water outlet channel 184 communicating with the bottom of the through hole 174. For example, one end of the water outlet passage 184 communicates with the through hole 174, and the other end is located at the front end of the heat dissipation groove 144. For example, the outlet channel 184 is inclined outwardly relative to the horizontal. So that the rainwater introduced into the through-hole 174 can flow out to the outside from the outlet passage 184.
For example, the two-way memory alloy strip 164 is a memory aluminum alloy; for another example, the two-way memory alloy strip 164 is a memory copper alloy; as another example, the two-way memory alloy strip 164 is another memory alloy with good thermal conductivity. The two-way memory alloy strip 164 has a first length when cooled and a second length when heated, the first length being less than the second length. The transformation temperature of the two-way memory alloy strip 164 is 70-120 ℃, that is, the two-way memory alloy strip 164 recovers to a high temperature phase shape when heated to 70-120 ℃, and at this time, the two-way memory alloy strip 164 deforms from the first length to the second length. Preferably, the transformation temperature of the two-way memory alloy strip 164 is 100 degrees Celsius. Like this, the area of contact increase of deformation to the two-way memory alloy strip 164 of second length and air, its radiating efficiency promotes this moment, can continue to absorb the heat that LED wick 134 produced fast to this process can make the heat that LED wick 134 produced distribute away by quick, has improved the radiating efficiency.
In order to further improve the heat dissipation efficiency, for example, the lengths of the two-way memory alloy strips in each two-way memory alloy strip group are different; as another example, the radii of the two-way memory alloy strips within each two-way memory alloy strip set may be different. Therefore, the two-way memory alloy strip can absorb heat in an unbalanced state, the two-way memory alloy strip with smaller radius and shorter length is heated rapidly, the time of the heating block reaching the metamorphosis temperature is shortened, the two-way memory alloy strip deforms from the first length to the second length rapidly after the time is shortened, and the heat dissipation efficiency is higher due to the fact that the contact area of the deformed two-way memory alloy strip and air is increased. For example, the two-way memory alloy strips in each two-way memory alloy strip group have a preset gap between every two-way memory alloy strips, so that air can flow between the two-way memory alloy strips to provide the heat dissipation efficiency of the two-way memory alloy strips.
As shown in fig. 5, for example, the ring-shaped mounting body 114 includes an outer layer 115, a graphene layer 125, an aluminum alloy layer 135, a copper alloy layer 145, and an inner layer 155, which are sequentially stacked, and the inner sides of the outer layer 115, the graphene layer 125, the aluminum alloy layer 135, the copper alloy layer 145, and the inner layer 155 are all clamped in the ring-shaped mounting groove. The annular mounting body 114 further comprises a plurality of positioning pins 165 for connecting the outer layer 115, the graphene layer 125, the aluminum alloy layer 135, the copper alloy layer 145 and the inner layer 155, wherein each positioning pin 165 penetrates through and is connected with the outer layer 115, the graphene layer 125, the aluminum alloy layer 135, the copper alloy layer 145 and the inner layer 155. For example, the outer layer 115 and the inner layer 155 are made of an aluminum-copper alloy material; for another example, the outer layer 115 and the inner layer 155 are made of corrosion-resistant stainless steel material; for another example, the outer layer 115 and the inner layer 155 are made of other heat dissipating plates. For example, graphene layer 125 is made of a stack of several graphene sheets; as another example, graphene layer 125 is made by filling graphene particles in a frame made of graphite. Thus, because the heat dissipation performance of each layer such as the outer tegument 115, the graphene layer 125, the aluminum alloy layer 135, the copper alloy layer 145 and the inner tegument 155 is different, the heat dissipation efficiency is also different, however, when the layer with better heat conductivity is heated up faster, the heat of the layer can be transferred to other layers, so that the overall heat dissipation effect of the annular mounting body 114 is in a dynamic equilibrium state, and because the speed of heat absorption of partial layers is fast, the temperature of the LED lamp wick 134 can be rapidly reduced, the heat dissipation efficiency is fast, and the service life of the LED lamp wick 134 is effectively prolonged.
For example, the outer layer 115 has a first gap 175 with the graphene layer 125, the graphene layer 125 has a second gap 185 with the aluminum alloy layer 135, the aluminum alloy layer 135 has a third gap 195 with the copper alloy layer 145, and the copper alloy layer 145 has a fourth gap 170 with the inner layer 155. For example, the height of the first gap 175, the height of the second gap 185, the height of the third gap 195, and the height of the fourth gap 170 are sequentially and equally spaced. Thus, because of the gaps between the layers, air can circulate in the gaps, and the flowing air can carry away some of the heat, thereby reducing the temperature of the lamp assembly 104.
As shown in fig. 5, for example, the heat dissipation groove 144 includes a groove bottom 1441 and two groove walls 1442, the two groove walls 1442 are respectively disposed on two sides of the groove bottom 1441, one end of the groove bottom 1441 is welded to the inner layer 155, an end of the groove wall 1442 is welded to the outer layer 115, and an end of the groove wall 1442 is further abutted to the graphene layer 125, the aluminum alloy layer 135, and the copper alloy layer 145, respectively, and with reference to fig. 3, it can be understood that the connection location 1141 is a location where an end of the groove wall 1442 is welded to the outer layer 115, and also includes a location where an end of the groove wall 1442 is further abutted to the graphene layer 125, the aluminum alloy. Referring to fig. 4, for example, the mounting area 106 is disposed on the side of the groove bottom 1441 facing away from the groove wall 1442, and the LED wick 134 is soldered on the groove bottom 1441 and is located in the mounting area 106. Thus, the heat generated by the LED wick 134 can be transferred to the inner layer 155 through the groove bottom 1441, and transferred to the outer layer 115, the graphene layer 125, the aluminum alloy layer 135 and the copper alloy layer 145 from the inner layer 155, and meanwhile, the heat generated by the LED wick 134 can also be transferred to the two groove walls 1442 through the groove bottom 1441, and transferred to the outer layer 115, the graphene layer 125, the aluminum alloy layer 135, the copper alloy layer 145 and the like from the two groove walls 1442, thereby reducing the temperature of the LED wick 134 and prolonging the service life thereof.
As shown in fig. 6, for example, a clamping groove 113 is disposed in a bottom end region of the lamp post 103 away from the rotating device 102, the waste recycling device 105 includes a semi-annular body 116 and three waste recycling boxes 126, a hook 123 is disposed on an inner side of the semi-annular body 116, and the hook 123 is engaged with the clamping groove 113. Three waste recovery boxes 126 are uniformly arranged on the semi-annular body 116. For example, the waste recycling box 126 is opened with a waste accommodating groove, and the opening of the waste accommodating groove faces the solar cell panel 101. The waste recycling device 105 can be removed from the light pole 103 at any time to dump the waste in the waste recycling bin 126.
As shown in fig. 7 and 8, for example, the semi-annular body 116 and the three waste recovery boxes 126 are integrally formed; for another example, the waste recovery bin 126 may be removably disposed on the semi-annular body 116. In this embodiment, the semi-annular body 116 is a prismatic semi-annular body, the two end regions and the middle region of the bottom of the semi-annular body 116 are respectively provided with a fastening position 1161, and the fastening position 1161 is a hooking groove. For example, the hooking groove is a half of the opening of the waste recycling bin 126, and a hook 1261 is arranged on one side of the hooking groove, and the hook 1261 is clamped in the hooking groove. For example, a clamping spring 1162 and a push block 1163 fixed at the end of the clamping spring are arranged on one side of the hooking groove, the push block 1163 is elastically abutted to the hook 1261, so that the hook 1261 is clamped in the hooking groove, the waste recycling box 126 is prevented from moving, when the waste recycling box 126 needs to be detached, the waste recycling box 126 only needs to be pushed in the elastic opposite direction, and then the hook 1261 is removed from the opening of the hooking groove, so that the waste recycling box is convenient and practical.
