[0002] Luminaires are lighting devices widely used in homes, businesses, and public spaces. They can be categorized into various types based on their function, design, and installation method. To dissipate heat, a heat sink is installed on one side of the lamp. This is a crucial component for dissipating heat generated within the lamp, thereby protecting the lamp components, extending its lifespan, and maintaining its normal operating temperature. With the increasing popularity of LED lamps, the importance of heat sinks in lamp design has become increasingly prominent.

[0003] However, the existing lamp radiators have the following disadvantages: the heat sinks on most lamp radiators are fixed on the heat dissipation base. Different lamps have different power and heat dissipation requirements, so lamp radiators with different heat sink spacing are required, and the distribution of higher heat positions in the lamps may be uneven, so heat sinks with the same spacing are not conducive to rapid heat dissipation, which will reduce the practicality of the lamp radiator. Therefore, the current lamp radiators need to be improved. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 5 and Figure 7 The utility model provides a technical solution: a lamp radiator with adjustable heat sink spacing, comprising a heat sink 1 and a limiting plate 4, a heat sink 1 is provided with a heat sink 2 below, a round rod 10 is connected to one side of the heat sink 1, the limiting plate 4 is arranged on the side of the heat sink 1 close to the round rod 10, and the limiting blocks 7 are fixed to the two ends of the limiting plate 4 close to the heat sink 1, a limiting groove 8 is provided on the inner side of the heat sink 1 close to the limiting block 7, a limiting mechanism 6 is provided in the built-in groove of the heat sink 1 close to the limiting groove 8, one side of the limiting mechanism 6 is connected to the limiting block 7, and the limiting mechanism 6 includes a support spring 601, a slide groove 602, a handle 603, an insertion rod 604 and a slot 60 5. A sliding groove 602 is provided inside the heat sink 1 near the limit groove 8, and a plug rod 604 is slidably connected inside the sliding groove 602. The plug rod 604 is connected to a handle 603 at one end near the outside of the heat sink 1. A support spring 601 is provided inside the sliding groove 602 near the top of the plug rod 604. A slot 605 is provided on the side of the limit block 7 near the plug rod 604. The heat sink 1 is provided with equally spaced adjustment grooves 5 below the heat sink 2. The limiting plate 4 is provided with equally spaced through holes 11 on the inner side near the round rod 10. The cross-sectional shape of one end of the heat sink 2 and the adjustment groove 5 is "T"-shaped, and the cross-sectional shape of the plug rod 604 is "L"-shaped.

[0025] In specific implementation, the heat sink on the existing lamp radiator is fixed on the heat sink base. Different lamps have different power and heat dissipation requirements, so lamp radiators with different heat sink spacing are required, and the position where the heat of the lamp is higher may be unevenly distributed. Heat sinks with the same spacing are not convenient for rapid heat dissipation, which will reduce the practicality of the lamp radiator. The spacing of the heat sink 2 can be adjusted according to the heat dissipation requirements of the lamp. Through the adjustment slots 5 distributed at equal intervals, the heat sink 2 can be inserted into the adjustment slots 5 with different spacings, and the heat sink can be placed at the position where the heat dissipation requirement is higher. 2 is installed closer, and then the handle 603 is pulled upward to make the handle 603 slide in the slide groove 602 and squeeze the support spring 601, and then the limit blocks 7 at both ends of the limit plate 4 are inserted into the limit groove 8, and at the same time the through hole 11 is sleeved on the outside of the round rod 10, and then the handle 603 is released to make the support spring 601 rebound and drive the insertion rod 604 to insert into the slot 605, limiting the position of the limit block 7. The limit plate 4 can make the heat dissipating fins 2 stably installed under the heat dissipating seat 1, and it is convenient to adjust the spacing of the heat dissipating fins 2, thereby improving the practicality of the lamp radiator.

[0026] See also Figures 1-6 The lamp board 3 is installed above the heat sink 1 by bolts, and a positioning mechanism 9 is installed above the heat sink 1 near the lamp board 3. The positioning mechanism 9 includes a positioning block 901, a connecting rod 902 and a return spring 903. The heat sink 1 is provided with a positioning block 901 above the lamp board 3, and a connecting rod 902 is connected to the bottom of the positioning block 901. The outer side of the connecting rod 902 is sleeved with a return spring 903. The connecting rod 902 is slidably connected to the built-in groove of the heat sink 1, and the cross-sectional shape of the positioning block 901 is "7" shaped.

[0027] During specific implementation, since the lamp is usually installed on the heat dissipation base of the radiator by bolts, before installation, it is necessary to manually press the lamp board 3 of the lamp to prevent the lamp board 3 from shifting, but this is more troublesome. The positioning block 901 can be pulled up and drive the connecting rod 902 to move upward, while squeezing the reset spring 903, and then the lamp board 3 is placed on the heat dissipation base 1 from left to right, and then the positioning block 901 is released, so that the reset spring 903 rebounds and drives the connecting rod 902 to pull the positioning block 901 downward, so that the positioning block 901 is against the top of the lamp board 3, which can limit the lamp board 3 once, facilitate the subsequent bolt installation, and improve the convenience of the lamp radiator.

[0028] Working principle: When using the lamp radiator with adjustable heat sink spacing, first, with the assistance of the positioning mechanism 9, the lamp board 3 can be quickly installed on the heat sink 1, and then the spacing of the heat sink fins 2 can be adjusted through the adjustment slot 5 according to the heat dissipation requirements of the lamp, and the heat sink fins 2 are limited and installed through the limiting mechanism 6 and the limiting plate 4. Then, when the lamp is working, heat is conducted through the heat sink 1 and introduced into several heat sinks 2, which is convenient and fast for heat dissipation. The setting of the limiting mechanism 6 and the positioning mechanism 9 improves the practicality and convenience of the lamp radiator.
