Description

Technical Field

[0001] The utility model belongs to the technical field of lighting, and particularly relates to an LED explosion-proof fluorescent lamp which is easy to dissipate heat. Background Art

[0002] In high-risk industrial environments such as petrochemical industry, oil depots and high dust content, lighting equipment not only needs to provide sufficient light, but also must have a high degree of safety to prevent explosion accidents caused by electric sparks or high temperatures. These areas usually contain flammable and explosive gases, liquids or dust, so extremely strict requirements are put forward for the explosion-proof performance of lamps.

[0003] Traditional explosion-proof lamps, especially LED explosion-proof fluorescent lamps, often face the balance problem between heat dissipation and cost in design. In order to achieve good explosion-proof performance, the lamp must have good sealing to isolate the internal electrical components from the external dangerous environment. However, this high degree of sealing often limits the heat dissipation inside the lamp, resulting in the LED chip and drive circuit being easily damaged due to overheating during long-term operation, thereby affecting the overall life and stability of the lamp.

[0004] To address this challenge, many explosion-proof lamps adopt complex radiator structures, but these radiators not only increase the manufacturing cost, but also may sacrifice the compactness and aesthetics of the lamp to a certain extent. In addition, the complex heat dissipation design may also lead to increased maintenance difficulty, which is not conducive to long-term stable operation in harsh environments.

[0005] Therefore, there is an urgent need for an LED explosion-proof fluorescent lamp that can effectively dissipate heat, has a reasonable cost and a simple structure. Content of the Utility Model

[0006] The purpose of the utility model is to provide an LED explosion-proof fluorescent lamp that is easy to dissipate heat in view of the deficiencies of the prior art. It not only has a remarkable heat dissipation effect, but also has a reasonable cost and a simple structure, which can ensure that the LED light source and drive circuit maintain an appropriate working temperature during continuous operation, thereby extending the service life of the lamp and improving the overall safety and reliability.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An LED explosion-proof fluorescent lamp that is easy to dissipate heat, comprising:

[0009] A first end cap and a second end cap, the end of the first end cap is provided with a wiring port, and a wiring terminal is arranged inside the first end cap;

[0010] A light-transmitting tube connected between the first end cap and the second end cap and hermetically arranged, and a protective cover and a protective net are arranged outside the light-transmitting tube;

An installation plane is provided on the outer side of the heat dissipation profile, and an LED lamp board is provided on the installation plane. The wiring terminal is connected to a wire that extends into the heat dissipation profile and is electrically connected to the LED lamp board.

[0012] Furthermore, two ends of the first end cap respectively form a wiring cavity and a fixing cavity. The wiring terminal is installed in the wiring cavity, and the fixing cavity is used to connect and fix the light-transmitting tube and the heat dissipation profile.

[0013] Furthermore, a fixing hole communicating with the fixing cavity is provided on the inner end face of the wiring cavity. A screw at one end of the wiring cavity passes through the fixing hole to fix the heat dissipation profile.

[0014] Furthermore, a wiring hole communicating with the fixing cavity is provided on the inner end face of the wiring cavity. The wire connected to the wiring terminal passes through the wiring hole and is connected into the heat dissipation profile.

[0015] Furthermore, a sealing gasket is provided between the edge of the inner side wall of the fixing cavity and the light-transmitting tube.

[0016] Furthermore, the first end cap and the second end cap have the same structure and both are provided with the wiring terminal. The wiring terminal in the first end cap is connected to the wiring terminal in the second end cap through the hollow area inside the heat dissipation profile.

[0017] Furthermore, the first end cap and the second end cap further include a cover plate. The cover plate covers the wiring cavity. The wiring port is located on the cover plate. A sealing ring is also provided between the cover plate and the wiring cavity.

[0018] Furthermore, the cross-section of the heat dissipation profile is polygonal, and a power supply component is installed inside the heat dissipation profile.
