For example, referring to fig. 3, the back surface of the lamp body 10 is a smooth arc structure, when the air flows, the hot air is dissipated to the surrounding environment through the back surface of the lamp body 10, the cold air flows downward, the air can flow along the arc structure, thereby reducing air flow disorder, making the air flow smoother, accelerating the convection of the cold air and the hot air to form a heat dissipation channel, and accelerating the heat dissipation of the lamp body 10 to the surrounding environment.

For another example, referring to fig. 4, when the lamp body 10 is used, the back of the lamp body 10 faces upward, that is, the falling direction of the foreign matters such as dust, rain stain, bird droppings, etc. due to its smooth surface, if there are foreign matters such as dust, fallen leaves, and animal excreta, etc., falling on the back of the lamp body 10, the back of the lamp body 10 is a smooth arc structure, so that the foreign matters (dust, fallen leaves, and animal excreta) can slide along the arc surface of the back by the gravity of the foreign matters, and will not be retained on the lamp body 10. Even if a small part of foreign matters are retained on the lamp body 10, the lamp body 10 can be washed clean when encountering wind or rain, thereby ensuring the high-efficiency heat dissipation of the heat dissipation surface of the lamp body 10.

In an implementable embodiment of the present invention, referring to fig. 5 to 7, the light source assembly 20 comprises a substrate 21 and a plurality of light sources 22 disposed on the substrate 21. The lamp body 10 has a plurality of heat sink structures 12 on the front surface thereof, and at least one light source 22 is correspondingly attached to each of the heat sink structures 12.

Through the different installation angle of first arcwall face 61 and second arcwall face 54, can make same bracing piece 60 and lamp body 10, realize two kinds of different mounting means, see fig. 12 and 13, but the level setting can be set up and can set up perpendicularly between bracing piece 60 and the lamp body 10, and bigger satisfying user's demand uses more in a flexible way.

In one implementation, the support rod 60 includes a connecting tube and a first arc surface 61 disposed at one end of the connecting tube. The connection pipe is used to connect the lamp body 10 to the installation position. For example, the connecting pipe is provided with a plurality of fixing screws, and the inner diameter of the connecting pipe can be changed by screwing the fixing screws, so that the connecting pipe is connected to the lamp post. The set screw includes, but is not limited to, an external hex-tooth screw. The first arc surface 61 has a through hole, and the input line 31 of the power supply 30 can extend into the inner cavity of the connecting tube through the through hole, so as to prevent the input line 31 of the power supply 30 from being routed from the outside of the connecting portion 50. The connecting pipe and the first arc surface 61 are integrally formed.

The first arc surface 61 may be an arc convex surface or an arc concave surface facing the connecting portion 50. Accordingly, the second arc-shaped surface 54 on the connecting portion 50 is a concave arc surface matching with the convex arc surface, or a convex arc surface matching with the concave arc surface. The second arc-shaped surface 54 is provided with a notch which is communicated with the through hole on the first arc-shaped surface 61 and is used for arranging a channel for the input line 31 of the power supply 30. The first arc-shaped surface 61 and the second arc-shaped surface 54 are provided with corresponding screw holes, and the first arc-shaped surface 61 and the second arc-shaped surface 54 can be connected through screws. The support rod 60 and the lamp body 10 can be horizontally and vertically arranged by changing different installation angles of the first arc-shaped surface 61 and the second arc-shaped surface 54.

Further, in the embodiment of the present invention, the first arc surface 61 is provided with an adjusting hole 62 extending along the arc surface, and the second arc surface 54 is provided with a fixing hole. The fastener passes through the adjustment hole 62 to connect with the fixing hole. In one achievable manner, the adjustment aperture 62 is kidney-shaped, i.e., extends along an arcuate surface. The fastener can be an adjusting bolt, the adjusting bolt comprises but is not limited to an internal hexagonal machine thread screw, and a gasket and an elastic sheet are further sleeved on the screw. The adjustment bolt passes through the adjustment hole 62 and then is connected with the fixing hole. The rotation angle between the first arc-shaped surface 61 and the second arc-shaped surface 54, i.e., the angle of the lamp body 10 relative to the support rod 60, can be defined according to the span of the adjustment hole 62. In a practical manner, referring to fig. 12 and 13, the lamp body 10 can be adjusted up and down by 15 degrees in the horizontal and vertical directions relative to the supporting rod 60, so as to meet the user's requirements more and the application is more flexible.

During the installation, the lamp body 10 of lamps and lanterns is connected the back with bracing piece 60, and the connecting seat angle between lamp body 10 and the bracing piece 60 is confirmed, and suitable angle between lamp body 10 and the bracing piece 60 can be adjusted to the relative rotation of rethread first arcwall face 61 and second arcwall face 54, and lamps and lanterns have the angle of shining that needs, then pass through adjusting bolt with the angle fixed.

After the installation is accomplished, when needing to adjust lamp body 10 again and shine the angle, only need loosen adjusting bolt soon, then rotate lamp body 10 for lamp body 10 rotates certain angle relative to bracing piece 60, then it can to tighten adjusting bolt again.

To sum up, adopt the utility model provides a lamps and lanterns can produce following technological effect at least:

1. the novel lamp can be applied outdoors, the back surface of the lamp body is of a smooth arc surface structure, foreign matters can be prevented from being accumulated, and therefore efficient heat dissipation of the heat dissipation surface of the lamp body is guaranteed. Meanwhile, airflow disorder is reduced, so that air circulation is smoother, cold and hot air convection is accelerated, and heat of the lamp body is accelerated to be dissipated to the surrounding environment;

2. the light source assembly conducts heat through the heat sink, so that the heat of the light source is conveniently and quickly transferred to the back of the lamp body, the heat conduction efficiency is higher, meanwhile, the heat concentration effect among the light sources is reduced, and the heat conduction and heat dissipation efficiency is improved;

3. different lampshade assemblies can be used interchangeably, so that market requirements are met;

4. the installation angle between the support rod and the lamp body is changed, so that the irradiation requirements of different angles of the lamp body can be realized, and the user requirements can be met;

5. the plurality of ventilation channels are arranged on the heat dissipation ribs in the lamp body, so that the contact area and the contact frequency of heat and the heat dissipation ribs can be effectively increased, the heat generated by the light source is quickly and thoroughly transmitted to the heat dissipation ribs, and is transmitted to the outside air by the lamp body connected with the heat dissipation ribs, and the heat dissipation effect of the lamp is further improved;

6. a section of space is reserved between the heat sink structure and the power supply to resist heat, or the heat-resisting plate is arranged to resist heat, so that heat of each heating body of the lamp is respectively radiated, and the radiating efficiency and the radiating performance of the lamp are improved.
