The housing 100 includes a bottom wall 110 and a plurality of side walls 120 connected to the bottom wall 110, the bottom wall 110 being parallel to the opening on a side facing away from the opening, the plurality of side walls 120 being disposed end to end so as to form a space for accommodating the lighting element 200 inside the housing 100.
Further, referring to fig. 1 and 2, in order to dissipate heat of the lighting device 200 to ensure the service life of the lighting device 200, the lighting device further includes a heat pipe assembly 300 and a heat dissipation assembly 400 disposed in the housing 100. Wherein, heat pipe assembly 300 is laminated with illumination piece 200 deviating from open-ended one side, and heat dissipation assembly 400 is laminated with one side that heat pipe assembly 300 deviates from heat pipe assembly 300 to realize that heat pipe assembly 300 absorbs the heat from illumination piece 200, the effect of heat dissipation assembly 400 quick heat dissipation is favorable to guaranteeing lighting device's radiating efficiency.
Because the working state of the lighting device 200 is usually kept at a certain angle with respect to the horizontal plane for a certain application place, at this time, the hot air is more likely to rise, so that the heat dissipation inside the heat dissipation assembly 400 is uneven, and the phenomenon of upper heat and lower cold easily occurs, so that the heat near the upper portion and the lower portion of the lighting device 200 is uneven, and the service life of the lighting device 200 is further affected. To solve this problem, as shown in fig. 2, the heat dissipation assemblies 400 may be two groups, and the two groups of heat dissipation assemblies 400 are disposed in parallel and spaced apart in the case 100 along the Y direction (first direction). Meanwhile, the bottom wall 110 is provided with a first ventilation hole 111, and the side walls 120 on both sides in the Y direction are provided with second ventilation holes 121, and the lighting device further includes a separation plate 500, wherein the separation plate 500 extends in the Z direction (second direction) and is disposed between the two groups of heat dissipation assemblies 400, so that the air flows entering the two groups of heat dissipation assemblies 400 through the first ventilation holes 111 are respectively discharged from the second ventilation holes 121 on both sides. The heat dissipation channels of the two groups of heat dissipation assemblies 400 are separated by the separation plate 500, the air quantity exhausted through the second ventilation holes 121 positioned above and below is the same, the shortage of the air quantity at the lower part is avoided, the upward circulation air quantity is placed to be larger than the downward circulation air quantity, the phenomenon that the upward and downward air quantities interfere with each other to generate upper heat and lower cold is avoided, the heat dissipation uniformity is improved, and the service life of the lighting part 200 is further prolonged.
Illustratively, the separator plate 500 herein may be of a simple thin plate structure, simple in structure, and low in cost.
The specific structure of the heat sink assembly 400 will now be described with reference to fig. 2.
The heat sink assembly 400 includes a heat sink 410 and a fan 420, and the heat sink 410 and the fan 420 are sequentially disposed in a direction away from the heat pipe assembly 300. The heat dissipation element 410 has the effect of rapid heat conduction and dissipation, and the fan 420 is beneficial to improving the air flow exchange between the inside of the heat dissipation element 410 and the external environment through the first ventilation hole 111 and the second ventilation hole 121, and is beneficial to further improving the heat dissipation effect.
More specifically, the heat sink 410 includes a bottom plate 411 and a plurality of first fins 412. Wherein, the bottom plate 411 is attached to the heat pipe assembly 300, and the plurality of first fins 412 are parallel along the X direction (third direction) and are arranged on the end surface of the bottom plate 411 facing away from the heat pipe assembly 300 at intervals, so that the interval between two adjacent first fins 412 corresponds to the second ventilation holes 121, and therefore, the interval between the first fins 412 is opposite to the first ventilation holes 111 on one hand, and opposite to the second ventilation holes 121 on the other hand, so that the air flow in the interval circulates rapidly, thereby achieving the effect of rapid heat dissipation and being beneficial to improving the heat dissipation efficiency of the heat dissipation assembly 400.
The fans 420 are multiple, the fans 420 are sequentially arranged along the X direction, and the fans 420 can be arranged according to the size of each heat dissipation part 410, so that the area acted by the fans 420 is improved, and the heat dissipation effect is improved.
Optionally, the first ventilation holes 111 are honeycomb holes, which is beneficial to improving the open area of the first ventilation holes 111, thereby improving the heat dissipation effect. Since the interval between the adjacent two first fins 412 extends in the X direction, in order to increase the heat dissipation passage of the second vent holes 121 corresponding to the interval, the second vent holes 121 are stripe-shaped holes extending in the X direction.
For the heat pipe assembly 300, the heat pipes 310 are included, and the heat pipes 310 are parallel and spaced along the Y direction, so that a single heat pipe 310 is penetrated up and down, which is beneficial to improving the uniformity of the upper and lower temperatures and avoiding the phenomenon of upper heat and lower cold. Meanwhile, the single heat pipe 310 is vertically penetrated, so that the ineffective heat conduction length of the two ends of the heat pipe 310 is reduced, and the heat conduction efficiency of the heat pipe 310 is improved.
Optionally, the cross-sectional shape of the heat pipe 310 is square, which is beneficial to increasing the contact area between the heat pipe 310 and the lighting device 200 and the heat dissipation assembly 400, thereby improving the heat conduction effect.
In addition, the lighting device further includes an electronic control assembly 600, wherein the electronic control assembly 600 is disposed in the housing 100, and the electronic control assembly 600 is located below the electronic control assembly 600 along the Y direction. Since the hot air moves upward, it is advantageous to provide the electronic control assembly 600 below to ensure the operating temperature. Meanwhile, the middle partition plate is beneficial to avoiding upward air quantity flowing downwards and beneficial to heat dissipation of the lower electronic control assembly 600.
Further, the electronic control assembly 600 includes a main body 610 and a plurality of second fins 620, where the plurality of second fins 620 are parallel and spaced on an end surface of the main body 610 near the heat pipe assembly 300 along the X direction, so that the second fins 620 can dissipate heat for the main body 610, and meanwhile, the second fins 620 enable the first fins 412 to be communicated with the second ventilation holes 121, so as to avoid shielding of the air duct by the main body 610.
The lighting device can be further provided with the mounting frame 700, and the mounting frame 700 is rotatably connected with two sides of the shell 100, so that the lighting direction of the lighting piece 200 can be adjusted, and the flexibility of the use process of the lighting device can be improved. Preferably, the direction in which the mounting bracket 700 is coupled to the housing 100 is perpendicular to the direction in which the second vent hole 121 is provided, so as to avoid interference between the mounting bracket 700 and the second vent hole 121.
