[0033] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] Please refer to Figures 1 to 3 , which is a floor lamp provided by an embodiment of the present utility model, including a base 100, a support column 200, and a lamp head 300. Among them, the support column 200 is connected to the base 100; the lamp head 300 includes a lamp socket 310, a heat dissipation base 320, and a plurality of first light source plates 330. The lamp socket 310 is connected to the top of the support column 200. The heat dissipation base 320 includes m first inclined plates 321 and n second inclined plates 322. Along the direction away from the support column 200, the first inclined plates 321 and the second inclined plates 322 are alternately connected in sequence and are arranged on the lamp socket 310. Each first inclined plate 321 is provided with a first light source plate 330 on the same side in a fitting manner. The first light source plate 330 is inclined forward relative to the support column 200 to emit light, where m≥2 and n≥1.

[0035] Among them, the first light source plate 330 is inclined forward relative to the support column 200 to emit light. For example, the first light source plate 330 is inclined downward, and the first light source plate 330 emits light downward in the inclined forward direction, so that it can directly hit the target position, such as the center position of the table; or, the first light source plate 330 is inclined upward, and the first light source plate 330 emits light upward in the inclined forward direction, so that it can directly hit the ceiling.

[0036] It can be understood that the heat dissipation base 320 is arranged with the first inclined plates 321 and the second inclined plates 322 alternately in sequence. The structure of the heat dissipation base 320 is simple. The lamp socket 310 can conveniently install the inclined first light source plates 330 in sequence through the heat dissipation base 320, and the second inclined plates 322 are not blocked in the light propagation path. Thus, the first light source plate 330 can emit light inclined forward.

[0037] Moreover, the first light source board 330 is attached to and connected with the first inclined plate 321 of the heat dissipation base 320, and the heat dissipation base 320 is designed with an alternating arrangement of the first inclined plate 321 and the second inclined plate 322, so that the heat dissipation base 320 has a large contact area with the external environment. In this way, the heat dissipation base 320 can preferably dissipate heat from the first light source board 330, thereby ensuring the service life of the first light source board 330.

[0038] In some embodiments, referring to Figure 2 and Figure 3 , the included angle between the first inclined plate 321 and the second inclined plate 322 is set to be greater than 90 degrees. With such a setting, the second inclined plate 322 is not likely to block the light emitting direction of the first light source board 330, thereby avoiding the second inclined plate 322 from interfering with the light emitted by the second light source board 340, and further ensuring the light projection effect of the second light source board 340 outward.

[0039] In some embodiments, a first heat sink 323 is provided on the back surface of the first inclined plate 321. More precisely, the first heat sink 323 is provided on the side of the first inclined plate 321 away from the first light source board 330; and / or, the first heat sink 323 is integrally provided on the back surface of the second inclined plate 322. More precisely, the first heat sink 323 is provided on the side of the second inclined plate 322 facing away from the first light source board 330. It can be understood that by providing the first heat sink 323 on the back surface of the first inclined plate 321 and / or the second inclined plate 322, the first heat sink 323 increases the contact area between the heat dissipation base 320 and the environment, thereby further enhancing the heat dissipation effect of the heat dissipation base 320.

[0040] Furthermore, the edges of the respective first heat sinks 323 away from the first inclined plate 321 or the second inclined plate 322 are set at the same height. Specifically, the lower edges of the respective first heat sinks 323 are flush. With such a setting, when the heat dissipation base 320 is installed on the lamp socket 310, the lower edges of the respective first heat sinks 323 can be attached to the inner wall of the lamp socket 310. Therefore, it is convenient to install the lamp socket 310 inside the lamp socket 310.

[0041] In some embodiments, referring to Figure 3 , the first inclined plate 321 is provided with a strip-shaped recess 3211, and the strip-shaped recess 3211 is recessed in a direction away from the first light source board 330. When fixing the first light source board 330, the fixing bolt passes through the first light source board 330 and is connected to the strip-shaped recess 3211. Thus, the first light source board 330 can be preferably fixedly installed on the inclined surface of the first inclined plate 321.

[0042] Further, a positioning surface 3212 is provided at a position where the first inclined plate 321 is close to the second inclined plate 322, and the lower edge of the first light source plate 330 is arranged in a fitting manner with the positioning surface 3212. It can be understood that during the installation process of the second light source plate 340, the second light source plate 340 is attached to the surface of the second inclined plate 322, and the lower edge of the second light source plate 340 is attached to the positioning surface 3212. In this way, the second light source plate 340 is accurately attached to the surface of the second inclined plate 322, so as to fix the second light source plate 340 with a fastening bolt subsequently.

[0043] In some embodiments, referring to Figure 2 and Figure 3 , the floor lamp includes a plurality of heat dissipation seats 320. Along the direction away from the support column 200, the ends of the heat dissipation seats 320 are spliced and connected in sequence. Thus, more first light source plates 330 can be arranged on the heat dissipation seats 320 in sequence. At the same time, the size of each heat dissipation seat 320 does not need to be set large, and the manufacturing difficulty of the heat dissipation seat 320 is reduced. Of course, the plurality of heat dissipation seats 320 can also be integrally arranged.

[0044] In some embodiments, referring to Figure 4 and Figure 5 , the floor lamp further includes a second light source plate 340. The second light source plate 340 is arranged on a side of the heat dissipation seat 320 away from the first light source plate 330. For example, the first light source plate 330 is arranged on the upper side of the heat dissipation seat 320, and the second light source plate 340 is arranged on the lower side of the heat dissipation seat 320. The heat dissipation seat 320 is equivalent to being arranged between the first light source plate 330 and the second light source plate 340. Therefore, the heat dissipation seat 320 not only helps the first light source plate 330 dissipate heat, but also helps the second light source plate 340 dissipate heat.

[0045] Further, the floor lamp further includes an upper cover plate 350, an upper light-transmitting plate 360 and a lower polarizing lens 370. Among them, the upper cover plate 350 is arranged at the upper opening of the lamp holder 310, and an upper light outlet is reserved on the upper cover plate 350. The first light source plate 330 is arranged inside the lamp holder 310 and emits light obliquely outward through the upper light outlet. The upper light-transmitting plate 360 can be an anti-glare plate, and the upper light-transmitting plate 360 is arranged at the upper light outlet. Thus, the light emitted by the first light source plate 330 passes through the upper light-transmitting plate 360 and emits light obliquely upward, so as to achieve an anti-glare light-emitting effect, and further ensure the comfort of the light.

[0046] At the same time, the second light source plate 340 is arranged inside the lamp holder 310, and the lower polarizing lens 370 is arranged at the lower light outlet of the lamp holder 310. The light emitted by the second light source plate 340 passes through the lower polarizing lens 370 and emits light outward. It can be understood that the lower polarizing lens 370 has a polarizing effect on the received light. Therefore, the light emitted by the second light source plate 340 emits light obliquely downward after passing through the lower polarizing lens 370.

[0047] In some embodiments, with reference to Figure 4 and Figure 5 , along the direction away from the support column 200, the two ends of the second light source board 340 are staggeredly arranged with the two ends of the heat dissipation base 320. For example, the second light source board 340 is arranged at a distance from the support column 200, and the lamp holder 310 is arranged close to the support column 200. That is, the front end portion of the second light source board 340 does not completely cover the area where the heat dissipation base 320 is located, so as to facilitate the heat dissipation of the first light source board 330 through the heat dissipation base 320 to the external environment of the lamp holder 310; similarly, the distance H1 from the end of the second light source board 340 away from the support column 200 to the support column 200, and the distance H2 from the end of the heat dissipation base 320 away from the support column 200 to the support column 200, H1 > H2. That is, the rear end portion of the heat dissipation base 320 does not completely cover the area where the second light source board 340 is located, so as to facilitate the heat dissipation of the second light source board 340 to the external environment of the lamp holder 310.

[0048] Among them, the second light source board 340 is arranged relatively backward with respect to the heat dissipation base 320, and an installation position is reserved on the lower side of the lamp holder 310 close to the support column 200 for arranging the human body detector 380. Among them, the human body detector 380 can be an infrared detector, a camera, etc. When the human body detector 380 detects that a user passes below the lamp head 300, the human body detector 380 detects the user, thereby controlling the floor lamp to automatically start.

[0049] In a specific embodiment, the lamp holder 310 defines a first light source cavity 311 with an upward opening. Along the direction away from the support column 200, the first light source cavity 311 is divided into a first cavity portion 3111 and a second cavity portion 3112. The heat dissipation base 320 is arranged in the first cavity portion 3111, and a second heat dissipation fin 313 is arranged at the bottom of the second cavity portion 3112. At the same time, the bottom of the lamp holder 310 is recessed inward to form a second light source cavity 312 with a downward opening. Along the direction away from the support column 200, a part of the second light source cavity 312 overlaps with a part of the first cavity portion 3111, and another part of the second light source cavity 312 overlaps with the second cavity portion 3112. The second light source board 340 is arranged in the second light source cavity 312. Thus, the two ends of the second light source board 340 are staggeredly arranged with the two ends of the heat dissipation base 320. And, the second heat dissipation fin 313 is equivalent to being arranged on the upper side of the second light source board 340, and the second heat dissipation fin 313 dissipates heat through the bottom of the second light source cavity 312, thereby indirectly facilitating the heat dissipation of the second light source board 340.

It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present utility model.
