The term "and / or" used in the specification includes any and all combinations of one or more related listed items.

[0028] Example 1:

[0029] As Figure 1 , 2 , 3, 4, 5, 6, a plant lighting lamp based on profile modularization, comprising a main body 1, a lighting assembly 2 and a power supply 3, the two ends of the main body 1 are provided with end covers 4, the power supply 3 is installed on the right side of the main body 1, the main body 1 is provided with a heat dissipation mechanism 5 for dividing heat sources and forming a cold and hot air circulation channel, the lighting assembly 2 comprises a circuit board 21, a first lens 22 and a second lens 23, the first lens 22 and the second lens 23 are symmetrically installed on the circuit board 21, and the circuit board 21 is provided with a first sealing pad 24 between the first lens 22 and the second lens 23.

[0030] As an embodiment, the heat dissipation mechanism 5 comprises a frame 51, a bottom plate 52 and a radiator 53, the frame 51 is arranged on the front and back sides of the bottom plate 52, and the radiators 53 are arranged on the bottom plate 52 in a spaced manner.

[0031] As an implementation form, the heat sink 53 comprises a plurality of heat dissipation modules which are detachably mounted on the frame 51 and the bottom plate 52.

[0032] As an implementation form, the bottom plate 52 is provided with a chimney 521.

[0033] As an implementation form, the circuit board 21 is provided with a notch 211 corresponding to the chimney 521.

[0034] As an implementation form, the first lens 22 and the second lens 23 are both in U-shaped structure.

[0035] As an implementation form, a plurality of openings 511 are arranged transversely on the lower side of the frame 51, and a positioning hole 512 for mounting the heat sink 53 is further arranged at the interval between the openings 511.

[0036] Due to the central tendency and upwardness of heat, the heat in the middle of the lamp is the highest in the whole lamp. In order to improve heat dissipation, the middle is hollowed out (chimney 521) to divide the heat source, and the temperature difference between the upper and lower sides is large. According to the upwardness of heat, hot air rises rapidly, forming a rapid pulling force on the air below the hollowed-out part. The cold air below is pulled to the upper side, and the cycle is repeated, quickly taking away the heat, forming a chimney effect. According to the design needs, if the middle cannot be hollowed out, the two sides can be hollowed out, and the effect is the same.

[0037] Modular assembly: the main body 1 is composed of standard profile units, which are cut according to the required power and length, and are connected by welding or bolts to form a complete shell, realizing "one mold with multiple specifications" production.

[0038] Optimization of heat dissipation: when heat is concentrated in the middle of the main body 1, the middle is hollowed out to divide the heat source, and the air circulation is formed by using the upwardness of hot air. If the middle cannot be hollowed out, the two sides can be hollowed out, and the cold and hot air is exchanged by the temperature difference, continuously taking away the heat.

[0039] The internal channel of the profile cooperates with the external fin to strengthen the diffusion of heat to the environment.

[0040] The side-mounted power supply 3 is integrated in the profile of the main body 1, which is convenient for installation and heat dissipation. The centralized power supply scheme embeds the DC / DC module in the end cavity, optimizing the space utilization.

[0041] Embodiment 2:

[0042] As shown in Figure 7 , 8 , this embodiment is basically the same as embodiment 1, except that the power supply 3 of this embodiment adopts a top-mounted design, and the specific structure is as follows:

[0043] The main body 1 is provided with end covers 4 at both ends for supporting the power supply 3, the end covers 4 are provided with supports 41, the end covers are connected with cross beams through the supports 41, the cross beams span the top of the main body 1, are made of profiles, and are hollow cavity structures inside for accommodating the power supply 3. The cross beam profiles are fixedly connected with the supports 41 through bolts, and the cross beams are provided with heat dissipation fins on both sides, forming a continuous heat dissipation channel with the heat dissipation mechanism 5 of the main body 1.

[0044] The beneficial effects of the embodiment are as follows:

[0045] Space optimization: the top-mounted power supply 3 is integrated in the cross beam profile, reducing the horizontal space occupation, and being suitable for the greenhouse environment with low layer height;

[0046] Heat dissipation cooperation: the cross beam heat dissipation fins and the main body radiator 53 cooperate, expand the heat dissipation area, and enhance the chimney effect due to the vertical channel through;

[0047] Convenient maintenance: the power supply 3 adopts a modular buckle design, and when disassembled, the end cover 4 does not need to be removed, and can be directly taken out from the top, facilitating quick replacement or upgrading.

Furthermore, the above technical features continue to be combined, forming various embodiments not listed above, which are considered to be within the scope of the description; further, for those skilled in the art, the above description can be improved or changed, and all these improvements and changes should belong to the protection scope of the appended claims of the utility model.
