Example 1
Fig. 1 and fig. 2 respectively show an explosion schematic diagram of the airflow control lamp and a structural schematic diagram of the airflow controller of the present embodiment, and fig. 3 shows an airflow trend schematic diagram of the airflow control lamp of the present embodiment. Referring to fig. 1 to 3, an airflow control lamp comprises a lamp body 1, an airflow controller 2, a reflecting shade 3 and a light source assembly 4, wherein the airflow control lamp forms an airflow control channel through the mutual matching among the airflow controller 2, the reflecting shade 3 and the lamp body 1, and guides external cold air to enter the lamp to realize heat exchange and then to be led out, so that the effect of heat dissipation is realized.
Specifically, the lamp body 1 includes a top case 11 and a power supply assembly 12, the power supply assembly 12 is installed between the top case 11 and the airflow controller 2, and the top case 11 is connected to the reflector 3 through the airflow controller 2. The reflector 3 includes a bottom plate 31 and a cover 32, and the light source assembly 4 and the airflow controller 2 are mounted on the bottom plate 31 of the reflector 3. Besides, the bottom plate 31 is also provided with the light-transmitting cover 5, so that the airflow control lamp has a good light-emitting effect.
The airflow controller 2 includes an airflow inlet 21 and an airflow guide 22. In the present embodiment, the gas inflow opening portion 21 and the gas flow guide portion 22 have a semicircular arc structure, and the gas inflow opening portion 21 and the gas flow guide portion 22 are connected to form the gas flow controller 2 having a circular structure as a whole. Wherein, the air inflow port 21 is circumferentially provided with a plurality of air flow control sheets 211, and an air flow inlet channel 212 is formed between every two air flow control sheets 211. The air flow control plates 211 are inclined from the outer edge of the air flow controller 2 toward the center of the air flow controller 2, i.e., radially distributed from the center of the air flow controller 2, so that the air flow inlet channels 212 are formed in a structure with wide outer edges and narrow inner edges. When the external air flows through the air inlet channel 212, the width of the air inlet channel 212 is gradually reduced to increase the flow speed, thereby increasing the contact between the lamp and the air and accelerating the heat exchange efficiency.
The airflow guiding portion 22 includes a flange 221 connected to the airflow inlet portion 21, and the flange 221 has an arc-shaped structure and forms a semi-surrounding structure with the airflow control piece 211. The outside air is blocked by the ribs 221 after entering from the air inlet channel 212 between the air flow control sheets 211, changes the air flow direction and moves toward the lamp body 1, thereby realizing the control of the air flow direction.
An air outlet 113 is provided at the top shell 11 of the lamp body 1. The top shell 11 is a cylindrical shell adapted to the structure of the airflow controller 2, and includes a bottom wall 111 and a side wall 112 connected to the bottom wall 111. In the present embodiment, the airflow outlet 113 is disposed on the opposite side of the top case 11 from the airflow inlet 21 and directly above the airflow guiding portion 22, so that the airflow is conveniently and rapidly guided out of the airflow outlet 113 after being blocked by the airflow guiding portion 22, and the airflow flowing speed is increased. The airflow outlet portion 113 is provided with a plurality of outlet grooves 114 for guiding out airflow. The airflow outlet groove 114 extends from the bottom wall 111 to the side wall 112 to form an overall structure in the shape of an "L". Wherein, the part of the outlet groove 114 positioned on the top shell 11 is communicated with the inside of the lamp body 1, thereby realizing the guiding out of the gas in the gas flow control lamp. Of course, the location and shape of the outlet slot 114 are not limited specifically, and in some embodiments, the outlet slot 114 is only disposed at the bottom wall 111 of the top shell 11, and in some embodiments, the outlet slot 114 is circular and distributed on the top shell 11. In addition, the relative positions of the airflow outlet 113 and the airflow inlet 21 and the airflow guide 22 are not exclusive.
In the use process of the airflow control lamp, the light source assembly 4 converts electric energy into heat energy and light energy, so that part of heat energy exists in the lighting process of the light source assembly 4 to heat air in the lamp. The air pressure in the air flow control lamp is reduced after being heated, and an air pressure difference is formed between the air pressure in the air flow control lamp and the air outside the air flow control lamp. Accordingly, the outside cool air enters the air flow controller 2 from the air flow inlet portion 21 by the air pressure difference. Air enters the airflow controller 2 from the side and, as it continues to move along the direction in which the airflow inlet passage 212 extends, changes its direction by encountering the airflow guide 22, and is then led out from the airflow outlet 113 at the top case 11. The mode of controlling the air flow to dissipate heat is not influenced by the environmental ventilation condition and the height of the air flow controller 2, and good heat dissipation effect can be realized under the environment with poor ventilation condition. Meanwhile, the air flow controller 2 has a simple structure and a compact structure, and therefore has lower production cost.
It is added that, in the process that the air reaches the air flow guiding portion 22 from the air flow inlet portion 21, the air traverses the whole air flow controller 2, so that the contact area between the air flow controller 2 and the air is increased, the exchange of cold and hot air in the air flow controller 2 is more sufficient, and the heat dissipation efficiency of the lamp is accelerated. In addition, since the light source assembly 4 and the airflow controller 2 are both mounted on the bottom plate 31 of the reflector 3, the air can timely take away the heat generated by the light source assembly 4 during the flowing process of the airflow controller 2, and further plays a role in enhancing the heat dissipation effect. In summary, the air inflow portion 21, the air flow guiding portion 22 and the air flow outlet portion 113 form a first air flow control channel, and air flows into the first air flow control channel due to air pressure difference and exchanges heat with hot air in the air flow controller 2, so that part of heat in the air flow control lamp is taken away, and a heat dissipation effect is achieved.
In particular, in the airflow controller 2, a plurality of heat dissipation fins 222 are further disposed on the outer peripheral wall of the flange 221 at intervals. The outer edges of the heat dissipation fins 222 and the outer edges of the air flow control plates 211 form a complete circle. The external cool air flows along the outer peripheral wall of the reflector 3 and passes between the heat radiation fins 222. The heat dissipation fins 222 have a block structure, so that they have a larger contact area with air. The gas carries away heat on the outer peripheral wall of the airflow controller 2 by heat exchange. In summary, a second air flow control channel is formed between the outside of the reflector 3 and the heat sink fins 222.
According to the airflow control lamp provided by the embodiment, external cold air enters the airflow controller 2 by utilizing the air pressure difference and is led out from the airflow outlet 113 of the lamp body 1 after heat exchange, and meanwhile, the heat in the airflow control lamp and the heat in the outer wall surface are taken away by utilizing the flowing of the cold air between the reflecting cover 3 and the heat dissipation fins 222 on the outer peripheral wall of the airflow controller 2, so that the heat dissipation efficiency and the heat dissipation effect of the airflow control lamp are greatly improved.
Example 2
The embodiment provides an airflow control lamp, which comprises a lamp body 1, an airflow controller 2, a reflecting shade 3 and a light source assembly 4. Wherein the airflow controller 2 includes an airflow inlet portion 21 and an airflow guide portion 22, and the lamp body 1 is provided with an airflow outlet portion 113. The airflow control lamp uses an air pressure difference to allow external cool air to enter the airflow controller 2 from the airflow inlet 21. The air flow traverses the air flow controller 2 in an initial direction and is in full contact with the interior of the lamp and exchanges heat until it encounters the air flow guide 22 and changes direction and is directed out of the air flow outlet 113 of the lamp body 1.
The difference between this embodiment and the airflow control lamp of embodiment 1 is that the back of the outer side of the flange 221 of the airflow guiding portion 22 is not provided with the heat dissipating fins 222. The outermost side of the rib 221 and the outer side of the air flow control plate 211 together form a complete arc-shaped structure.
Example 3
Fig. 4 is an assembly schematic diagram of an airflow control lamp according to the present embodiment, and as shown in fig. 4, the airflow control lamp according to the present embodiment includes a lamp body 1, an airflow controller 2, a reflector 3, and a light source assembly (not shown in fig. 4). Wherein the airflow controller 2 includes an airflow inlet portion 21 and an airflow guide portion 22, and the lamp body 1 is provided with an airflow outlet portion 113. The airflow control lamp uses an air pressure difference to allow external cool air to enter the airflow controller 2 from the airflow inlet 21. The air flow traverses the air flow controller 2 in an initial direction, is in full contact with the interior of the lamp and exchanges heat, changes direction when the air flow encounters the air flow guide 22, and is led out from the air flow outlet 113 of the lamp body 1.
The present embodiment is different from the embodiment in that two air flow outlet portions 113 are provided on the lamp body 1, one of the air flow outlet portions 113 being provided on the opposite side of the top case 11 from the air inflow portion 21 and being located directly above the air flow guide portion 22, and the other air flow outlet portion 113 being located directly above the air inflow portion 21. The airflow outlet 113 is provided with a plurality of outlet grooves 114 at intervals, and the outlet grooves 114 extend from the bottom wall 111 to the side walls 112 to form an overall structure in an L shape. The portion of the outlet groove 114 located in the top case 11 communicates with the inside of the lamp body 1, thereby realizing the discharge of the gas inside the gas flow control lamp.
The foregoing is merely illustrative and explanatory of the utility model as it is described in more detail and is not thereby to be construed as limiting the scope of the utility model. It should be noted that modifications and improvements can be made by those skilled in the art without departing from the spirit of the utility model, and that these obvious alternatives fall within the scope of the utility model.
