Description

Technical Field

[0001] The utility model belongs to the technical field of lamps, in particular to a heat dissipation type high-power landscape lamp. Background Art

[0002] In contemporary urban spaces and natural scenic areas, landscape lighting has become an indispensable element of beautification. It is not only a visual enjoyment, but also a clever display of the integration of art, history and natural environment. Landscape lighting focuses on the harmonious coexistence with the cultural heritage and surrounding environment of the area where it is located. Through the carefully designed light layout and unique lighting design, it greatly enhances the visual charm of the garden or scenic area at night, creating a harmonious and fascinating night view spectacle, and covering the city at night with a mysterious and charming veil.

[0003] The existing authorization announcement number is CN213299827U, which is a new type of angle-adjustable LED lamp, including a lamp holder, a turntable, a bracket, a shell, a bulb, a lampshade, a heat dissipation device, and a rotating shaft. The turntable is movably engaged with the lamp holder. When the LED lamp is turned on, the heat dissipation device starts to operate, and then the motor at the rear end of the insulation block starts to rotate, driving the fan blades to rotate to suck air from the air duct, and driving the air outlet at the upper end of the lampshade to suck air toward the outside. The flowing air passes through the LED lamp board to reduce the heat, and then enters the air duct through the air filter. Then part of the heat dissipated by the air is absorbed by the heat sink and guided to the outside air. The remaining flowing air is discharged toward the heat sink through the support frame by the fan blades to the outside.

[0004] This heat dissipation method is to inhale air from the outside through a fan. When the air enters the shell, it will flow through the LED light board, thereby reducing the heat of the LED light board. However, the heat dissipation effect of this air suction and cooling is not obvious enough. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] Please refer to Figure 1-4 ;

[0027] A heat dissipation type high-power landscape lamp comprises an angle adjustment base 1 for realizing the angle adjustment function of the landscape lamp. The angle adjustment base 1 is connected to a lamp holder 2 for mounting a circuit board. Specifically, a slot is provided on the lamp holder 2. The angle adjustment base 1 and the slot on the lamp holder 2 are installed by sliding insertion, which is convenient for disassembly and installation of the lamp. A heat dissipation component 3 is fixedly installed on the lamp holder 2. A lighting component 4 is fixedly installed on the heat dissipation component 3. The lighting component 4 is cooled by the heat dissipation component 3.

[0028] The heat dissipation component 3 includes a fan 31 and a heat conducting plate 32 attached to the lighting component 4. The fan 31 is used to blow air directly to the heat conducting plate 32 to directly reduce the temperature of the heat conducting plate 32. The heat conducting plate 32 can be made of a material with good thermal conductivity, such as aluminum, copper and other metals. Due to the excellent thermal conductivity and lightweight characteristics of aluminum, the utility model preferably uses an aluminum heat conducting plate 32. The end surface of the heat conducting plate 32 facing away from the lighting component 4 is provided with a plurality of heat dissipating members 33. The heat dissipating members 33 are fixedly connected to the heat conducting plate 32. When the lighting component 4 is powered on and generates heat, the heat conducting plate 32 absorbs the heat of the lighting component 4, and the heat dissipation The heat sink 33 absorbs the heat of the heat conducting plate 32. Several heat sinks 33 extend downward for fixed connection with the lamp holder 2. At the same time, the heat sink 33 extending downward can also increase the range of heat dissipation, further promoting the absorption and release of heat. The heat sinks 33 are arranged in a ring array, and a gap is reserved between every two heat sinks 33 as the inlet and outlet of the air flow to ensure the circulation of air. An air flow channel 34 is provided between the several heat sinks 33 for guiding the air flow into the space enclosed by the several heat sinks 33. The fan 31 is installed near the lower end of the heat sink 33, not at the lowest end, for convenient air intake.

[0029] Specifically, when the landscape light is powered on, the lighting component 4 lights up and generates heat, the heat conducting plate 32 absorbs the heat of the lighting component 4 and transfers it to the heat sink 33. At the same time, the fan 31 starts and draws air from the outside through the gaps left between the heat sinks 33. The inhaled air flows upward under the action of the fan 31, and contacts the heat sink 33 during the upward flow, taking away the heat absorbed by the heat sink 33, and then reaches the top and contacts the heat conducting plate 32, absorbing the heat on the heat conducting plate 32, and finally discharges the air that has absorbed the heat from the gap, absorbs the heat generated by the lighting component 4 through the heat conducting plate 32, improves the heat dissipation effect, avoids the lighting component 4 from being overheated and reducing its service life, and absorbs the heat of the heat conducting plate 32 through the heat sink 33, thereby expanding the heat dissipation range and avoiding heat accumulation, which leads to heat dissipation difficulties.

[0030] In this embodiment, heat dissipation grooves 331 are opened on the inner sides of several heat dissipation elements 33 to shield the gas so that it will not flow out directly from the gaps between the heat dissipation elements 33 when it flows upward. Through holes 332 connected to the heat dissipation grooves 331 are provided on the outer edges of several heat dissipation elements 33. At least one through hole 332 is provided to discharge the gas after absorbing heat to prevent the gas from staying inside the heat dissipation component 3 and causing the temperature to rise.

[0031] Furthermore, in the space enclosed by the plurality of heat sinks 33, a plurality of first heat sinks 35 and second heat sinks 36 fixedly connected to the heat conducting plate 32 are provided. The length of the first heat sink 35 is greater than that of the second heat sink 36. The first heat sink 33 and the second heat sink 33 also absorb the heat of the heat conducting plate 32, and the air is blown away by the fan 31 to further improve the heat dissipation efficiency. The plurality of first heat sinks 35 and the second heat sink 36 extend downward, and their heights are all less than the heat sink 33 to form a cavity, which is used to install the fan 31.

[0032] Furthermore, a plurality of first heat sinks 35 are distributed in a circular array, and a plurality of second heat sinks 36 are distributed in a circular array in a space enclosed by the plurality of first heat sinks. The first heat sinks 35 and the second heat sinks 36 enclose a circular structure, so that the airflow flows in a circular shape.

[0033] Furthermore, a third heat sink 37 is provided between the second heat sinks 36 to enhance the heat dissipation effect. The third heat sink 37 is shorter than the first heat sink 35 and is provided on a side close to the first heat sink 35 to disperse the airflow and make the heat dissipation more uniform.

[0034] In the present embodiment, a plurality of first heat sinks 35, second heat sinks 36 and third heat sinks 37 are arc-shaped heat sinks with the same bending direction, and there is a certain distance between adjacent heat sinks. The arc-shaped first heat sinks 35, second heat sinks 36 and third heat sinks 37 are arranged in a clockwise direction or a counterclockwise direction. There is no limitation here. By setting each heat sink to an arc shape, on the one hand, the heat dissipation area of ​​the inner heat sink can be increased to further improve the heat dissipation efficiency. On the other hand, since the shape of the lamp is round, the arc-shaped heat sink is more in line with the structural shape of the lamp, which is convenient for guiding the airflow of the fan 31 while improving the structural rationality and aesthetics of the interior of the lamp.

[0035] In this embodiment, the lighting assembly 4 includes an outer shell 41, a light-transmitting plate 42 is provided on the top of the outer shell 41, light penetrates to the outside through the light-transmitting plate 42, an inner shell 43 is provided at the lower end of the light-transmitting plate 42, a seal 44 is abutted between the inner shell 43 and the light-transmitting plate 42, and the seal 44 is made of rubber material, which can effectively prevent dust, water, etc. from entering the interior of the lamp housing, and a PCB board 45 is provided inside the inner shell 43 that is in contact with the heat conducting plate 32, and a lamp bead 46 is provided on the PCB.

[0036] In this embodiment, a wiring port 47 is provided on the heat conducting plate 32, and a avoidance port 38 is provided at the lower end of the wiring port 47 located on one side of the first heat sink 35. The wiring port 47 and the avoidance port 38 are connected to the lamp holder 2, and the wires of the PCB board 45 pass through the wiring port 47, the avoidance port 38 and the lamp holder 2 in sequence, and are electrically connected to the circuit board in the lamp holder 2. In addition, the avoidance port 38 is arranged on the outside of the L-shaped baffle 39, and the fan 31 is arranged on the inside of the L-shaped baffle 39. The fan 31 is separated from the wires by the L-shaped baffle to prevent the wires from being interrupted by the fan 31.

[0037] In this embodiment, the angle adjustment base 1 includes a fixing member 11 and a bracket 12. The fixing member 11 and the bracket 12 are fixedly connected by a connecting member. The connecting member can be a pin or a bolt, etc. A plurality of annular array blocks 111 are provided on one side of the fixing member 11, and a block 2 121 staggered and engaged with the block 1 111 is provided on the bracket 12. Specifically, the block 1 111 and the block 2 121 are staggered and engaged, and the fixing member 11 and the bracket 12 are locked by the connecting member, so that the illumination angle of the landscape lamp cannot be adjusted without removing the connecting member. If the illumination angle of the landscape lamp is to be adjusted, the connecting member needs to be removed, the locking of the bracket 12 and the fixing member 11 is released, the angle of the lamp is manually rotated, and then the block 2 121 and the block 1 111 are staggered and engaged with each other, and finally the connecting member is plugged in to lock the lamp.
