Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically a heat dissipation LED lamp. Background Technology

[0002] A light-emitting diode, or LED for short, is a commonly used light-emitting device that releases light through the recombination of electrons and holes. It has wide applications in the lighting field. LEDs can efficiently convert electrical energy into light energy and have extensive uses in modern society, such as lighting, flat panel displays, and medical devices.

[0003] Many inexpensive or older LED lights use only a simple aluminum substrate or a few fins for passive heat dissipation, lacking active cooling measures such as fans. This causes the LED chip to accumulate a large amount of heat during long-term operation, resulting in excessively high junction temperatures. This leads to two serious problems: Light decay: The light becomes dimmer and dimmer, and the light emission efficiency decreases; Sharply reduced lifespan: LED chips and packaging materials age faster at high temperatures, and a lamp with a nominal lifespan of 50,000 hours may actually only have 20,000 hours or even less. Many lighting fixtures use an integrated or glued design, making disassembly very difficult. If the LED chips or driver power supply are damaged, the entire fixture often needs to be replaced. This leads to the following problems: High maintenance costs: Even if only a small component fails, the user has to pay for a completely new light.

[0004] Not environmentally friendly: It causes unnecessary waste of resources and electronic waste.

[0005] High barrier to entry for repairs: Even ordinary users and repairmen find it difficult to perform component-level repairs. Utility Model Content

[0006] The purpose of this invention is to provide a heat dissipation LED lamp to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a heat dissipation LED lamp, comprising a protective housing, a back frame fixedly disposed on the rear side of the protective housing, heat dissipation fins snapped onto the rear side of the back frame, a cooling fan fixedly disposed on the rear side of the heat dissipation fins, a cover plate fixedly disposed on the rear side of the back frame, an LED lamp board fixedly connected to the back frame by bolts, and a heat-conducting component fixedly disposed at the middle position of the rear side of the LED lamp board.

[0008] A transparent window is fixedly installed on the rear side of the protective housing.

[0009] Power supply battery compartments are fixedly installed at both ends of the rear side of the LED light panel.

[0010] A cable inlet hole is provided at the bottom center of the back frame.

[0011] The front side of the heat dissipation fins penetrates the cover plate and contacts the heat conduction components.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention employs a combination of heat-conducting components, heat dissipation fins, and a cooling fan. This combination of active and passive heat dissipation is highly efficient, rapidly reducing and maintaining the junction temperature of the LED chip at a low level. This effectively prevents the LED chip from experiencing light decay due to high temperatures, greatly extends the lifespan of the LED board, and maintains stable luminous efficiency output.

[0013] This utility model uses a back frame as the main skeleton, with modular assembly of various parts, such as snap-fit ​​heat dissipation fins, which simplifies production, assembly, and maintenance. If a component (such as a fan or light panel) is damaged, it can be replaced relatively easily, reducing maintenance costs. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0017] Please see Figure 1-4This utility model provides a technical solution: a heat-dissipating LED lamp, including a protective housing 1, a back frame 6 fixedly mounted on the rear side of the protective housing 1, and heat dissipation fins 3 snapped onto the rear side of the back frame 6. The heat dissipation fins 3 are the core component of passive heat dissipation, which increases the contact with air through a large surface area, thereby quickly dissipating heat into the surrounding air. A cooling fan 4 is fixedly mounted on the rear side of the heat dissipation fins 3, and a cover plate 5 is fixedly mounted on the rear side of the back frame 6. The cover plate 5 serves to seal and support, ensuring that the heat dissipation fins can stably contact the heat-conducting components. An LED lamp board 9, the core light-emitting component of the lamp, is fixedly connected to the back frame 6 by bolts. Multiple LED chips are integrated on the back of the LED lamp board 9. A heat-conducting component 8 is fixedly mounted at the middle position of the rear side of the LED lamp board 9, which is the starting point of the heat dissipation system. It is tightly attached to the back of the LED lamp board (the main heat source) and is responsible for quickly absorbing and conducting the heat generated by the chips to the heat dissipation fins behind it.

[0018] A transparent window 2 is fixedly installed on the rear side of the protective housing 1. The protective housing 1 serves as the main structure and protective shell of the LED light, used to install and fix all internal components and protect them from external impacts, dust and moisture. The transparent window 2 is usually made of glass or plastic with high light transmittance. Its function is to allow the light emitted by the LED light panel to be transmitted efficiently, while sealing the front end to provide protection.

[0019] Both ends of the rear side of the LED light panel 9 are fixedly equipped with battery compartments 7 for installing backup batteries. When the main power supply is interrupted, the LED lights can continue to illuminate for a period of time using the batteries.

[0020] A cable inlet hole 10 is provided at the bottom center of the back frame 6, and air inlets are provided on the left and right sides of the back frame 6.

[0021] The front side of the heat dissipation fin 3 penetrates the cover plate 5 and contacts the heat conduction component 8.
