Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically a floodlight with a toothed process, suitable for indoor and outdoor lighting scenarios such as roads, stadiums, and squares. Background Technology

[0002] In the field of LED lighting, floodlights, as high-power lighting devices, are widely used in scenarios such as roads, stadiums, and squares. In existing technologies, floodlights typically use heat sinks manufactured using die-cast aluminum or cold forging processes, and their core structure includes the following characteristics:

[0003] Radiator structure: Traditional radiators are mostly formed by die casting or cold forging, which requires mold processing, resulting in high production costs and long production cycles. In addition, the radiator is thick to ensure structural strength, which increases the overall weight (usually ≥8kg), making it difficult to meet the requirements of lightweight replacement.

[0004] Insufficient heat dissipation efficiency: Die-cast aluminum material has a low thermal conductivity (approximately 90-120 W / m·K), and the heat sink surface is mostly flat or has a simple fin design, resulting in low air circulation efficiency. This causes the LED chip operating temperature to be higher than 75℃ for a long time, accelerating light decay (measured light decay rate ≥10% / year).

[0005] Limited environmental adaptability: Most floodlights only have lenses on their emitting surface and lack a glass protective structure. The waterproof design relies on an overall seal, which can easily lead to aging of the rubber rings in extreme temperature or high humidity environments, resulting in a decrease in the protection level (usually below IP65).

[0006] Installation structural defects: Traditional mounting brackets are made of steel or die-cast aluminum, which are heavy and have poor corrosion resistance (requiring electroplating or spraying treatment). They are prone to rust when used outdoors for a long time, increasing maintenance costs. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figures 1-5 As shown

[0035] A floodlight based on a toothed heat sink technology, characterized in that it comprises:

[0036] The lamp body assembly 1 includes a toothed heat sink 11; its back is provided with an X-shaped heat dissipation groove 111, and a stainless steel baffle 12 for enhancing structural strength is fixed on its side; it also includes an aluminum substrate, LED chips, a junction box, and a stainless steel baffle. The LED chips are attached to the aluminum substrate, which is fixed to the surface of the toothed heat sink to achieve heat conduction. The LED chips are electrically connected to the connecting wire 42. The depth of the X-shaped heat dissipation groove 111 of the toothed heat sink 11 is 3-5mm, and the groove spacing is 10-15mm.

[0037] The lens assembly 2 is detachably connected to the front end of the lamp body assembly 1 and includes a lens 21 and a cover 22. A waterproof rubber ring 23 is provided between the cover 22 and the lens 21. A glass plate 24 is provided on the inner side of the cover 22. A lens waterproof rubber ring 25 is provided between the lens 21 and the lamp body assembly 1.

[0038] Mounting bracket assembly 3 is fixed to lamp body assembly 1; the shovel-tooth heat sink 11 is made of pure aluminum. Mounting bracket assembly 3 is made of aluminum alloy with powder coating.

[0039] The power supply assembly 4 includes a drive power supply 41 and connecting wires 42, and the power supply assembly 4 is fixed on the mounting bracket assembly 3.

[0040] The lens assembly of this utility model is mainly the optical part of the lamp. It can be composed of a lens or a lens + glass, and different angle lenses are selected according to different venues and application requirements. The lamp body assembly is the core part of the product, mainly composed of an aluminum substrate, LED chips, a heat sink, a junction box, and related accessories. The LED chips are attached to the aluminum substrate, and the aluminum substrate is fixed to the heat sink. The heat dissipation of the entire lamp is conducted to the heat sink through the aluminum substrate, and then the heat sink dissipates the heat into the air, thereby achieving the cooling of the LED chips. The mounting bracket assembly is the mounting part of the entire lamp. Its material is aluminum alloy with a powder-coated surface, which has the characteristics of being lightweight and highly corrosion-resistant. The power supply assembly consists of a driver power supply, related wires, and connectors, and has the characteristics of high efficiency, easy installation, and long life.

[0041] This utility model's heat sink is made of pure aluminum and formed using a toothed process. This process eliminates the need for molds, resulting in fast production speed, stable quality, and low cost. Pure aluminum heat sinks have high thermal conductivity and are lightweight, effectively reducing the temperature of LED chips and the overall weight of the lamp. The X-shaped heat dissipation grooves 111 machined on the back of the heat sink are a unique design feature, effectively increasing airflow and improving heat dissipation efficiency. Because pure aluminum heat sinks have relatively low strength, stainless steel baffles are added to the sides of the toothed heat sink 11 to effectively prevent deformation from impacts during transportation. The faceplate 22 of this utility model can be fitted with glass; by replacing the faceplate 22 and adding a waterproof gasket between the glass and the lens 21, the product becomes waterproof.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
