Description

Built-in heat dissipation geometric floodlight Technical Field

[0001] This utility model relates to a floodlight, and more specifically, it relates to a geometric floodlight with built-in heat dissipation. Background Technology

[0002] Floodlights are common decorative lighting fixtures, precise lighting devices with narrow beam angles that concentrate light onto specific areas or objects, achieving a decorative effect by focusing light onto designated locations. To address heat dissipation, most floodlights on the market incorporate external heat dissipation fins, affecting their aesthetics and overall appearance. Furthermore, the integrated design of the light source and power supply in these floodlights can lead to cross-heating between the two sources, further increasing the demands on the external heat dissipation fins. In some high-power floodlights, the heat dissipation area of ​​the fins must be increased, further reducing the floodlight's aesthetics and making it unsuitable for surface mounting indoors. Therefore, further research and improvement of the structure of these geometric floodlights are necessary. Summary of the Invention

[0003] One of the objectives of this utility model is to address the aforementioned shortcomings by providing a built-in heat dissipation geometric floodlight. This aims to solve the technical problems of existing floodlights, such as their simple structure, the mutual influence of heat sources between the light source and the power supply, the high requirements for heat dissipation structure, the impact on the aesthetics of the lamp body, and the inability to be used in the open.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model provides a built-in heat dissipation geometric floodlight, including a heat dissipation housing, a light source module installed inside the heat dissipation housing, a light-transmitting cover installed on the upper part of the heat dissipation housing, heat dissipation fins provided on the inner wall of the heat dissipation housing, and an annular gap provided in the middle of the heat dissipation housing, the annular gap communicating with the inner cavity of the heat dissipation housing, and a bottom cover installed at the bottom of the heat dissipation housing; an electrical housing is also provided at the lower part of the heat dissipation housing, a power supply component is installed inside the electrical housing, the power supply component is electrically connected to the light source module, and an electrical cover is installed at the lower part of the electrical housing.

[0006] As a preferred further technical solution, the upper part of the electrical housing is provided with a support arm, a scale cover is installed on the support arm, the scale cover is passed through a rotating shaft, the rotating shaft is also poweredly connected to a rotating wheel, the rotating wheel is movably installed on the support arm, the rotating wheel is also poweredly connected to the lower part of the bottom cover, the rotating shaft is also provided with a pointer for cooperating with the scale cover, and the rotating shaft is used to drive the heat dissipation housing to rotate on the support arm through the rotating wheel.

[0007] A further technical solution is that a sealing ring is provided between the electrical cover and the electrical housing, and the electrical housing is rotatably mounted on the chassis.

[0008] A further technical solution is that the electrical casing is fixed to the chassis with screws.

[0009] A further technical solution is that the light source module is positioned vertically above the annular gap.

[0010] Compared with the prior art, one of the beneficial effects of this utility model is that by separating the light source module and the power supply component, the heat sources of the light source and the power supply are avoided from interfering with each other when the geometric floodlight is in use, and the heat dissipation requirement is significantly reduced. Furthermore, the heat sink of the heat dissipation shell can be set on its inner wall, and air convection heat dissipation can be achieved through the annular gap, eliminating the need for an external heat sink and avoiding the heat sink affecting the aesthetics of the lamp body. This allows the floodlight to be used in surface mounting. At the same time, the built-in heat dissipation geometric floodlight provided by this utility model has a simple structure, is suitable for industrial production, and is easy to promote.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Referring to Figure 1, one embodiment of this utility model is a built-in heat dissipation geometric floodlight. This embodiment designs the geometric floodlight as a split structure, comprising a heat dissipation housing 1 and an electrical housing 6. A light source module 2 is installed inside the heat dissipation housing 1, and a light-transmitting cover 3 is installed on the upper part of the heat dissipation housing 1. More importantly, in this embodiment, heat sinks are designed on the inner wall of the heat dissipation housing 1, and an annular gap 101 is designed in the middle of the heat dissipation housing 1, connecting the annular gap 101 to the inner cavity of the heat dissipation housing 1. Air convection cooling is achieved through the annular gap 101 in conjunction with the heat sinks inside the heat dissipation housing 1. A bottom cover 5 is installed at the bottom of the heat dissipation housing 1 to ensure that the interior of the heat dissipation housing 1 remains sealed. The aforementioned electrical housing 6 is located below the heat dissipation housing 1, and a power supply component is installed inside the electrical housing 6. This power supply component is electrically connected to the light source module 2. An electrical cover 7 is installed at the lower part of the electrical housing 6, thus making the heat dissipation housing 1 and the electrical housing 6 independent of each other, preventing the heat sources of the light source module 2 and the electrical component from interfering with each other. Preferably, for the purpose of facilitating heat dissipation, the aforementioned light source module 2 is positioned vertically above the annular gap 101.

[0016] Furthermore, to facilitate adjustment of the floodlight's illumination angle, a support arm 8 can be installed on the upper part of the electrical housing 6, based on the aforementioned split-type heat dissipation housing 1 and electrical housing 6 structure. To facilitate viewing the adjustment angle, a scale cover 9 is first installed on the support arm 8. Correspondingly, a pointer cooperating with the scale cover 9 is also installed on the rotating shaft 10. The aforementioned scale cover 9 is passed through a rotating shaft 10, which is poweredly connected to a rotating wheel 11. The rotating wheel 11 is movably mounted on the support arm 8 and is also poweredly connected to the lower part of the bottom cover 5 of the heat dissipation housing 1, allowing the rotating shaft 10 to drive the heat dissipation housing 1 to rotate on the support arm 8 via the rotating wheel 11. This facilitates adjustment of the floodlight's vertical illumination angle.

[0017] On the other hand, to ensure the airtightness of the electrical housing 6, a flexible sealing ring 12 can be provided between the electrical cover 7 and the electrical housing 6. At the same time, the electrical housing 6 can be rotatably mounted on the chassis 4 to facilitate the adjustment of the horizontal angle of the floodlight. Through the aforementioned rotatable mounting method, the floodlight can achieve 360-degree angle adjustment on the chassis 4. Furthermore, to facilitate the fixation of the horizontally adjusted angle, the electrical housing 6 can also be fixed to the aforementioned chassis 4 with screws.

[0018] In this embodiment, by separating the light source module 2 and the power supply component, the heat sources of the light source and the power supply are prevented from interfering with each other when the geometric floodlight is used. Furthermore, the heat sink of the heat dissipation housing 1 can be placed on the inner wall, and air convection heat dissipation can be achieved through the annular gap 101, eliminating the need for an external heat sink and avoiding the heat sink affecting the aesthetics of the lamp body, thus allowing the floodlight to be used in an exposed manner.

[0019] It should be noted that the power supply component and light source module 2 used in the above embodiments of this utility model, as well as the electrical connection method between the power supply component and light source module 2, are similar to the structure of similar projection lamps in the prior art. The main purpose of this utility model is to provide a split projection lamp with a built-in heat sink to improve the aesthetics of the projection lamp and facilitate the adjustment of the horizontal and vertical illumination angles. Therefore, the structure and implementation principle of the aforementioned components will not be described in detail. Those skilled in the art can refer to the disclosed projection lamp structure to obtain the structure and principle of the aforementioned components in order to realize this utility model.

[0020] Referring to Figures 1 and 2, in a preferred embodiment of this invention, the base 4 is fixedly installed at the desired installation position of the floodlight. Then, the electrical cover 6 is movably installed on the base 4. The horizontal illumination angle of the floodlight can be adjusted by rotating the base 4. Once the ideal horizontal angle is reached, the electrical cover 6 is fixed to the base 4 with screws to maintain the current horizontal illumination angle. Then, the angle of the heat sink 1 is adjusted by rotating the rotating shaft 10 (generally, the rotating shaft 10 can be parallel to the horizontal plane). During adjustment, the vertical illumination angle can be precisely controlled according to the angle value indicated by the pointer on the rotating shaft 10 on the scale cover 9. After adjusting to the ideal vertical angle, the self-locking function between the rotating wheel and the support arm 8 is used to stop the current position. Then, the electrical components are connected to the power supply for light transmission. The aforementioned self-locking function can take various forms, such as ratchet self-locking or self-locking achieved by the contact friction between the rotating wheel 11 and the support arm 8.

Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this utility model.
