DETAILED DESCRIPTION

[0033] The applicant of this case has studied the problem that lamps in the prior art, especially outdoor lamps, are prone to failure, and found that there are contradictory requirements in the structural design of outdoor lamps. Electronic components such as batteries need to be tightly wrapped in the shell to prevent contact with foreign objects such as rainwater or dust, and the environment in which they are located must be ventilated to dissipate heat as quickly as possible. In order to resolve this contradiction, the applicant of this case provides a street lamp with an electric control box, which can use dual fans to allow the airflow to fully exchange heat in the shell to take away heat, and the fan cover is provided with a uniquely structured protection unit, which can reduce the entry of foreign objects such as rainwater and dust into the shell, achieving the purpose of not affecting heat dissipation and protecting electronic components. Its technical solution is described in detail in the following embodiments.

[0034] See also Figure 1 The street lamp with an electric control box provided by the present invention comprises an electric control box 1, a lamp body 2, a solar panel 3 and a support base 4, wherein the electric control box 1, the lamp body 2 and the support base 4 are all installed below the solar panel 3. The support base 4 is located at a side away from the lamp body 2, and the electric control box 1 is located between the support base 4 and the lamp body 2. The support base 4 is used to connect with a support member such as a lamp pole, so that the entire lamp with the electric control box can be set at a high place.

[0035] See also Figures 2 to 5 The electric control box 1 includes an electric component 10 and a heat dissipation box 20 .

[0036] The electrical component 10 includes a substrate 11 and a battery 12, wherein the substrate 11 and the battery 12 are stacked and electrically connected. The lamp body 2 and the solar panel 3 are electrically connected to the substrate 11 respectively, and the solar panel 3 converts light energy into electrical energy through the substrate 11 and supplies power to the lamp body 2, and the excess electrical energy is stored in the battery 12.

[0037] The heat dissipation box 20 includes a shell 21, an end cover 22, an air inlet fan 23, an air outlet fan 24 and a protection unit 25. In this embodiment, the shell 21 extends in the horizontal direction, is hollow inside and has openings at opposite ends in the horizontal direction, and the end cover 22 covers the openings at both ends of the shell 21, thereby forming a storage space, and the electrical component 10 is installed in the storage space. The front side 211 of the shell 21 faces the support seat 4, and two mounting holes 215 are opened on the front side 211 of the shell 21, and the two mounting holes 215 are arranged in the left and right directions and separated by a distance. The air inlet fan 23 and the air outlet fan 24 are respectively close to the two mounting holes 215 and are electrically connected to the substrate 11, so that external air is blown into the storage space and the air in the storage space is extracted from the storage space, wherein the air inlet fan 23 and / or the air outlet fan 24 can be located on the inner side of the front side 211, or pass through the mounting holes 215 so that at least a part of them is located on the outer side of the front side 211. Furthermore, a mounting portion 216 is provided on the top wall of the housing 21, and the mounting portion 213 protrudes toward the accommodation space. The electrical component 10 is fixed to the mounting portion 213 by screws or the like and is separated from the bottom wall of the housing 21 by a distance to prevent the electrical component 10 from being affected by water accumulated inside the housing 21. In this embodiment, the housing 21 includes a front side surface 211 and a rear side surface 212 extending in the up-down direction and arranged opposite to each other, an upper side surface 213 and a lower side surface 214 arranged in the up-down direction and connected between the front side surface 213 and the rear side surface 212, respectively, and the lamp body 2 is located on a side close to the rear side surface 214.

[0038] Please refer to Figures 5 to 8, the protection unit 25 is respectively covered on the outside of the two mounting holes 215, and includes a support frame 251, a protection cover 252, a filter 253, a first seal 254 and a second seal 255. The support frame 251 is arranged outside the front side 211 of the housing 21, and a through hole 2511 communicating with the mounting hole 215 is opened in the middle thereof. In one embodiment, the mounting hole 215 is coaxial with the through hole 2511 and the aperture of the through hole 2511 is greater than or equal to the mounting hole 215, and the through hole 2511 surrounds the outside of the mounting hole 215. The air inlet fan 23 or the air outlet fan 24 is located in the through hole 2511. In this embodiment, projected along the axis of the through hole 2511, the outer contour of the support frame 251 is a rectangle surrounded by the upper side, the lower side, the left side and the right side, and the through hole 2511 is opened in the middle thereof. The filter screen 253 covers the side of the through hole 2511 facing away from the housing 21 to prevent foreign matter from entering the housing 21 through the through hole 2511. The protective cover 252 is a semi-enclosed box body with an opening at one end, the opening of which faces the support frame 251 and covers the side of the support frame 251 facing away from the housing 21. The filter screen 253 is located between the support frame 251 and the protective cover 252. In this embodiment, the protective cover 252 surrounds the upper side, lower side, left side and right side of the support frame 251 and is separated by a certain distance; along the axis of the through hole 2511, the four corners of the support frame 251 are provided with protrusions 2512 protruding toward the protective cover 252, and the protective cover 252 abuts against the protrusions 2512 toward the inner side wall of the support frame 251, so that the inner side wall of the protective cover 252 is separated from the through hole 2511 by a distance, thereby forming a gas channel connected to the through hole 2511. The first sealing member 254 and the second sealing member 255 are sealing rings made of rubber or the like. The first sealing member 254 is arranged between the support frame 251 and the housing 21 to seal the gap between the support frame 251 and the housing 21. The second sealing member 255 is disposed between the filter screen 253 and the support frame 251 and surrounds the through hole 2511 to seal the gap between the filter screen 253 and the support frame 251 .

[0039] In one embodiment, the bottom of the protective cover 252 is provided with a plurality of drainage holes 2521, and rainwater entering the protective cover 252 can flow out of the drainage holes 2521 to prevent rainwater from accumulating in the protective cover 252. In this embodiment, the drainage holes 2521 are provided on the bottom wall surface of the protective cover 252 facing the lower side of the support frame 251 and away from the support frame 251, so that rainwater can quickly leave the protective cover 252. Furthermore, the inner bottom surface of the protective cover 252 is inclined toward the drainage holes 2521 to speed up the outflow of rainwater.

[0040] In one embodiment, connected drainage grooves 2513 are provided on the upper side, left side and right side of the support frame 251. Through the drainage grooves 2513 extending from the top of the support frame 251 to the bottom thereof, part of the rainwater entering the protective cover 252 from the top can be guided to the drainage hole 2521.

[0041] In one embodiment, Fig. 9 As shown, the front side surface 211 of the shell 21 is tilted relative to the vertical direction, so that the distance from the side where the front side surface 211 and the lower side surface 214 are connected to the rear side surface 212 is smaller than the distance from the side where the front side surface 211 and the upper side surface 213 are connected to the rear side surface 212, and the protection unit 25 is tilted accordingly, the outer side surface above the protection cover 252 tends to face away from the shell 21, and the outer side surface below tends to face the shell 21, and the drainage hole 2521 faces the shell 21, so that rainwater is not easy to enter the protection cover 252 when it hits the top of the protection cover 252, while rainwater in the protection cover 252 easily flows out of the protection cover 252.

[0042] In one embodiment, Fig.10 As shown, along the vertical projection, the front side surface 211 of the shell 21 is provided with two relatively inclined mounting portions 216, and the two mounting portions 216 extend from the middle to the left and right end covers 22 respectively, and the distance to the rear side surface 212 gradually increases. The air inlet fan 23, the air outlet fan 24, the protection unit 25 and the two mounting holes 215 are respectively provided on the two mounting portions 216, so that the air inlet fan 23 and the air outlet fan 24 are inclined to each other, and most of the airflow drawn in by the air inlet fan 23 flows to the end cover 22 on one side, then rebounds to the end cover 22 on the other side, and then rebounds to the air outlet fan 24, thereby extending the time that the gas stays in the accommodating space, so that the heat exchange is more sufficient.

[0043] Please refer to Figure 7 and Figure 8, the air flow is shown by the arrows in the figure. When working, the air inlet fan 23 forms a negative air pressure, and the gas flows into the protective cover 252 from the opening of the protective cover 252 covering the outside of the air inlet fan 23 along the upper side, lower side, left side and right side of the support frame 251, reaches the through hole 2511, and then flows into the accommodating space, and flows toward the air outlet fan 24 under the action of the air outlet fan 24. Under the push of the air outlet fan 24, it flows out of the accommodating space from the through hole 2511 of the protective cover 252 covering the air outlet fan 24, and then flows from the protective cover 252 covering the air outlet fan 24 and the support frame 251, until it flows from the protective cover 252 to the external space, thereby taking away the heat in the accommodating space. In this process, since the air inlet fan 23 and the air outlet fan 24 are located on the same side of the shell 21, the incoming gas needs to flow through the interior of the entire shell 21 before flowing out, so as to fully contact the substrate 11 and the battery 12 in the storage space and take away their heat, thereby achieving a good heat dissipation effect. The protective cover 252 and the support frame 251 surround the outside of the air inlet fan 23 and / or the air outlet fan 24, and the gas needs to pass through a circuitous gas channel to enter the storage space, thereby reducing rainwater, dust, etc. from entering the interior of the storage space.

[0044] In addition, the lamp of the present invention is powered by solar energy, but according to needs, the lamp of the present invention can also be powered by other DC or AC external power sources. The heat dissipation box 20 can also have other heating elements to protect and dissipate heat.

[0045] Compared with the prior art, the lamp with an electric control box of the present invention has the following advantages:

[0046] 1. It can not only dissipate heat inside the electric control box, but also reduce the entry of rainwater, dust and other foreign objects into the box;

[0047] 2. It can quickly drain the rainwater accumulated in the protection unit;

[0048] 3. Good sealing;

[0049] 4. Airflow can enter the box from multiple directions, increasing the airflow inside the box.

[0050] 5. The electrical components in the box are not easily exposed to foreign objects such as rainwater.

[0051] 6. Compact structure, small space occupation and little light obstruction.
