In the process of practicing the present invention, the inventor found that at present, the outdoor lamps used still have some deficiencies, for example, the heat dissipation of the lamp body is not good. Foreign matter is easy to stay on the lamp body, such as dust, fallen leaves and animal excrement. The foreign matter covers the surface of the lamp body and affects the heat dissipation effect of the lamp body.

In order to solve the defects in the prior art, an embodiment of the present invention provides a lamp, which can prevent accumulation of foreign objects on the lamp body and improve the heat dissipation efficiency of the lamp body.

The implementation of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings and embodiments, so as to fully understand and implement the implementation process of how to apply technical means to solve technical problems and achieve technical effects in the embodiments of the present invention.

FIG. 1 is a schematic diagram of an exploded structure of a lamp according to an embodiment of the present invention, and FIG. 2 is a schematic diagram of the internal structure of a lamp body 10 according to an embodiment of the present invention, as shown in FIGS. 1 and 2 .

An embodiment of the present invention provides a lamp including: a lamp body 10 , a light source assembly 20 , a power source 30 and a lampshade assembly 40 .

The lamp body 10 includes a front surface and a back surface, the front surface of the lamp body 10 has a accommodating cavity 11 , and the back surface of the lamp body 10 has a smooth arc structure. The light source assembly 20 is disposed in the accommodating cavity 11 and connected to the front surface of the lamp body 10 . The power supply 30 is arranged in the accommodating cavity 11 and is connected to the front of the lamp body 10 ; The lampshade assembly 40 is connected to the lamp body 10 and covers the accommodating cavity 11 ;

It should be noted that what is shown in the dashed box in FIG. 1 is an implementable manner of the lampshade assembly 40 , and the specific implementation manner will be described in detail in the following content, and will not be described in detail here.

According to the technical solutions provided by the embodiments of the present invention, a new lamp is provided. The lamp can be used outdoors. The back of the lamp body 10 has a smooth arc surface structure, which can prevent the accumulation of foreign objects, thereby ensuring the high efficiency of the heat dissipation surface of the lamp body 10. At the same time, the turbulence of the air flow is reduced, the air circulation is smoother, the convection of the cold and hot air is accelerated, and the heat of the lamp body 10 is quickly dissipated to the surrounding environment.

For example, referring to FIG. 3 , the back of the lamp body 10 has a smooth arc surface structure. When the air flows, the hot air is dissipated to the surrounding environment through the back of the lamp body 10 , and the cold air flows downward, and the air can follow the arc surface. The structure is flowing, the airflow disturbance is reduced, the air circulation is smoother, the convection of the cold and hot air is accelerated to form a heat dissipation channel, and the heat of the lamp body 10 is quickly dissipated to the surrounding environment.

For another example, referring to FIG. 4 , the back of the lamp body 10 faces upwards when in use, that is, the falling direction of foreign objects such as dust, rain stains, and bird droppings. The excrement, etc., falls on the back of the lamp body 10. Since the back of the lamp body 10 is a smooth arc surface structure, foreign objects (dust, leaves and animal excrement) can follow the back arc with the help of the gravity of the foreign objects. The shape surface slides off and does not stay on the lamp body 10 . Even if a small amount of foreign matter remains on the lamp body 10 , it will be washed clean when it encounters wind or rain, thereby ensuring the efficient heat dissipation of the heat dissipation surface of the lamp body 10 .

In an implementable embodiment of the present invention, referring to FIGS. 5 to 7 , the light source assembly 20 includes a substrate 21 and a plurality of light sources 22 disposed on the substrate 21 . The front surface of the lamp body 10 has a plurality of heat sink structures 12 , and at least one light source 22 is correspondingly attached to each heat sink structure 12 . In the embodiment of the present invention, the lamp body 10 may be provided with a connecting column, and the connecting column is used to connect the substrate 21 . The base plate 21 can be connected to the connecting column by screws, for example, connected to the connecting column by means of cross recessed pan head screws. In order to avoid damage to the base plate 21 caused by the screw, a spacer is provided on the screw. The heat sink can penetrate through the entire front of the lamp body 10 , so that the heat sink can directly transfer the heat generated by the light source assembly 20 to the entire lamp body 10 . The attachment of the light source 22 to the heat sink facilitates that the heat of the light source 22 can be quickly transferred to the back of the lamp body 10 , and the heat conduction efficiency is higher and the heat dissipation efficiency is higher.

In the embodiment of the present invention, the light source 22 in the light source assembly 20 can be realized by the LED light source 22, and the light source 22 can be arranged in various ways, such as: matrix type, inline type, ring type, star type, etc., the light source 22 The arrangement of the heat sinks matches the arrangement of the heat sinks.

Further, in order to improve the heat dissipation effect of the heat sink, a plurality of heat dissipation ribs are arranged in the circumferential direction of each heat sink structure 12 . Through the heat dissipation ribs, the heat on the heat sink has multiple transfer paths during the transfer process, so that the heat can be transferred to the lamp body 10 faster. In addition, each heat dissipation rib is correspondingly attached with at least one light source 22 . The number of the light sources 22 on the light source assembly 20 can be increased by the heat dissipation ribs. When the number of the light sources 22 is constant, the heat dissipation ribs can make the light sources 22 more dispersed and avoid the heat concentration of the light sources 22 .

Further, in order to make the heat on the heat sink dissipate faster, in the embodiment of the present invention, at least one first ventilation channel (not shown in the figure) is provided on the outer periphery of each heat sink structure 12 . One way of realizing the first ventilation channel is that each heat sink is symmetrically lowered around the circumference. For example, the circumference of each heat sink is symmetrically lowered by 3-5mm, so that the hot air between the heat sinks can be circulated and transferred, and the heat dissipation effect is better. .

In another implementation manner, the first ventilation channel may be formed by a channel between two adjacent heat dissipation ribs, there are multiple channels in the entire heat sink structure, and air can circulate in this channel , in order to take away the heat generated by the light source 22 and fully contact the heat dissipation ribs, so as to quickly and thoroughly transfer the heat generated by the light source 22 to the heat dissipation ribs during operation, and then pass through the heat dissipation ribs. The lamp body 10 is transferred into the air, thereby improving the heat dissipation effect of the lamp.

Further, please refer to FIG. 14 , which is a schematic three-dimensional structure diagram of a lamp body of a lamp provided by an embodiment of the present invention. A second ventilation channel 14 is formed around the outer edge of the front surface.

Specifically, along the length direction of the heat dissipation rib, the heights of the two ends of the heat dissipation rib are lower than the height of the middle position, that is, the height of the two ends of the heat dissipation rib close to the lamp body 10 is lower, and the height of the middle position is lower. It is designed in this way that when the light source assembly 20 is placed on the lamp body 10 , the ventilation channel 14 can be formed on the periphery of the heat sink structure, that is, on the outer edge of the front surface of the lamp body 10 . A ventilation channel is formed around the lower edge of the light source assembly 20, and this design can further strengthen the heat generated by the light source assembly 20 to circulate in the accommodating cavity 11 (in the direction of the arrow in the figure), enhancing the heat The contact area and number of times with the heat dissipation ribs, and then the heat is quickly and completely transferred to the heat dissipation ribs, and is transferred to the outside air by the lamp body 10 connected with the heat dissipation ribs, thereby further improving The heat dissipation effect of the lamp is improved.

In addition, each of the heat dissipation ribs is provided with at least one groove 15, and the positions of the grooves 15 on two adjacent heat dissipation ribs do not correspond, and a plurality of the grooves 15 are connected to the heat sink structure. A third ventilation channel 16 is formed (in the direction of the arrow in the figure).

Specifically, each of the heat dissipation ribs is provided with at least one groove 15 , and these grooves communicate with each other to form the third ventilation channel 16 , and the heat generated by the light source assembly 20 can pass along the third ventilation channel 16 . and fully contact with the heat dissipation ribs during the circulation process, and further transfer heat to the heat dissipation ribs quickly and thoroughly, and the lamp body 10 connected to the heat dissipation ribs It is transmitted to the outside air, thereby further improving the heat dissipation effect of the lamp; here, by setting the positions of the grooves 15 on the two adjacent heat dissipation ribs to be non-corresponding, multiple grooves 15 can be avoided. When the setting positions are corresponding, the heat quickly passes through the channels formed by these grooves 15 without effectively contacting the heat dissipation ribs, which can effectively increase the contact area and number of heat between the heat dissipation ribs and the heat dissipation ribs. The heat-dissipating rib is transferred to the heat-dissipating rib, and is transferred to the outside air by the lamp body 10 connected with the heat-dissipating rib, thereby further improving the heat-dissipating effect of the lamp.

Furthermore, please refer to FIG. 15 , which is a schematic diagram of a side structure of a lamp body of a lamp according to an embodiment of the present invention.

Specifically, the ventilation holes 17 are arranged around the bottom of the lamp body 10 , and the arrangement positions of these ventilation holes 17 correspond to the arrangement positions 14 of the second ventilation passages 14 inside, which can be understood as The second ventilation channel 14 can be communicated with the outside air through the ventilation hole 17, and the structure is designed so that the heat generated inside the lamp can form an effective convection with the outside air, so that the cooler outside air can pass through the outside air. The ventilation holes 17 enter the accommodating cavity 11 to exchange heat with the heat sink structure (the heat dissipation ribs), and take away the heat generated by the light source assembly 20 during operation and transferred to the heat dissipation ribs. The purpose is to quickly dissipate heat for the lamp, improve the heat dissipation performance of the lamp, and prolong the service life of the lamp.

It should be pointed out here that since the lamp needs to meet certain waterproof requirements, special treatment needs to be done on the shape and structure of the ventilation hole 17, such as setting the position of the internal opening of the ventilation hole 17 higher than the ventilation hole The position of the external opening, that is, the ventilation hole 17 is arranged obliquely on the lamp body 10, the internal opening is closer to the arc top of the lamp body 10, and the external opening is close to the opening of the lamp body 10, so as to prevent the Rainwater backflow brings unnecessary waterproof hazards to the lamp, so that the heat dissipation performance of the lamp can be improved and the use quality of the lamp can be improved on the basis of meeting the waterproof requirement of the lamp.
