Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a pluggable tube lamp. Background Technology

[0002] Plug-in tube lights, as the name suggests, are lighting fixtures that are installed and replaced by inserting and removing them from the lamp holder. They represent a replacement and upgrade for traditional fluorescent tubes. Currently, common plug-in tube lights on the market typically consist of a lamp holder, a power supply compartment containing the driver, a light source assembly, and a light-transmitting tube. The light source assembly is often an aluminum substrate or flexible circuit board with soldered LED chips. Since the aluminum substrate or flexible circuit board is generally opaque, encapsulating it within the light-transmitting tube means that only the side with the LED chips emits light. This results in a concentrated light direction, a small beam angle, uneven light distribution, and the potential for localized dark areas, making it difficult to achieve omnidirectional light emission. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a pluggable tube lamp with a simple structure that can achieve omnidirectional light emission.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A pluggable tube light includes a lamp holder, a light-transmitting tube, a light source assembly, and a power supply compartment with a driving power supply inside. The lamp holder is located at the upper end of the power supply compartment, and the light-transmitting tube is located at the lower end of the power supply compartment. The light source assembly is disposed inside the light-transmitting tube and electrically connected to the driving power supply. The light source assembly is an LED filament.

[0005] The power compartment has an upper opening, and the lamp holder has a lamp holder connector that mates with the upper opening of the power compartment. The lamp holder connector is detachably embedded in the upper opening of the power compartment.

[0006] The inner wall of the upper opening of the power compartment is provided with a mounting protrusion, and the corresponding position of the outer wall of the lamp holder is provided with a mounting groove into which the mounting protrusion can be engaged. The mounting protrusion is engaged in the corresponding mounting groove to realize the detachable connection between the lamp holder and the power compartment.

[0007] The upper surface of the mounting buckle is an inclined surface that slopes downward from the outside to the inside.

[0008] The power compartment has a side opening, and a cover is detachably provided on the side opening.

[0009] The power compartment is provided with two positioning mounting walls, which are arranged opposite each other with a left-right gap. Each positioning mounting wall is provided with a positioning groove. An insertion gap is formed between the outer wall of each positioning mounting wall and the inner wall of the adjacent power compartment. Insertion walls are provided on the left and right sides of the cover, respectively, extending towards the inner cavity of the power compartment. Positioning protrusions are provided on the inner walls of the insertion walls at positions corresponding to the positioning grooves. The insertion walls are inserted into the corresponding insertion gaps, and the positioning protrusions are engaged in the corresponding positioning grooves, thereby realizing a detachable connection between the cover and the power compartment.

[0010] The lower end of the power supply compartment is provided with a mounting cavity for inserting the upper end of the light-transmitting lamp tube. The upper end of the light-transmitting lamp tube is fixedly inserted into the mounting cavity.

[0011] The LED filament is supported and installed inside the light-transmitting tube by a fixing bracket. The main body of the fixing bracket is located inside the light-transmitting tube and at the upper end of the light-transmitting tube.

[0012] The light-transmitting tube is a glass tube.

[0013] Compared with the prior art, the advantages of this utility model are: With a simple structure, the light source component uses a linear and transparent LED filament, which is installed inside the light-transmitting tube to achieve 360° light emission. This allows light to be emitted evenly from the entire circumference of the light-transmitting tube, solving the problem of local dark areas in traditional tube lights and resulting in better lighting effects. Because the whole light source achieves omnidirectional light emission, the beam angle of the entire lamp is significantly increased, allowing the light to be spread more widely and softly into the surrounding space, improving the comfort of lighting and the overall quality of the spatial light environment.

Detailed Implementation

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0016] As shown in the figure, a pluggable tube lamp includes a lamp holder 1, a light-transmitting tube 2, a light source assembly 3, and a power supply compartment 5 with a driving power supply 4 inside. The lamp holder 1 is located at the upper end of the power supply compartment 5, and the light-transmitting tube 2 is located at the lower end of the power supply compartment 5. The light source assembly 3 is located inside the light-transmitting tube 2 and is electrically connected to the driving power supply 4. The light source assembly 3 is an LED filament.

[0017] In this specific embodiment, the power supply compartment 5 has an upper opening, and the lamp holder 1 has a lamp holder connector 11 that mates with the upper opening of the power supply compartment 5. The lamp holder connector 11 is detachably embedded in the upper opening of the power supply compartment 5. This achieves a modular and detachable connection between the lamp holder 1 and the power supply compartment 5. This split structure simplifies the production and assembly process, facilitates subsequent maintenance or component replacement, and improves the maintainability of the product.

[0018] In this specific embodiment, a mounting protrusion 51 is provided on the inner wall of the upper opening of the power compartment 5, and a mounting groove 111 is provided on the corresponding position of the outer wall of the lamp holder connector 11 for the mounting protrusion 51 to engage. The mounting protrusion 51 engages with the corresponding mounting groove 111 to achieve a detachable connection between the lamp holder 1 and the power compartment 5. Through the cooperation of the mounting protrusion 51 and the mounting groove 111, quick installation and locking between the lamp holder 1 and the power compartment 5 are achieved, resulting in a firm connection and high assembly efficiency.

[0019] In this specific embodiment, the upper end face 511 of the mounting protrusion 51 is a sloping end face that slopes downward from the outside to the inside. The design of the sloping end face serves as a guide. When installing the lamp holder 1, the sloping end face can guide the mounting protrusion 51 to slide smoothly into the mounting groove 111, making the installation process smoother and less strenuous, avoiding harsh jamming, and improving the assembly experience and efficiency.

[0020] In this specific embodiment, the power supply compartment 5 has a side opening 52, and a cover 50 is detachably mounted on the side opening 52. The design of the side opening 52 and the cover 50 greatly facilitates the installation, debugging and maintenance of the drive power supply 4. It eliminates the need to operate from the lamp holder 1 or the lamp tube end; the power supply can be accessed directly by opening the side cover 50, which improves production efficiency and the convenience of after-sales maintenance.

[0021] In this specific embodiment, two positioning mounting walls 53 are provided inside the power supply compartment 5, which are arranged opposite each other with a left-right gap. Each positioning mounting wall 53 is provided with a positioning groove 531. An insertion gap 530 is formed between the outer wall of each positioning mounting wall 53 and the inner wall of the adjacent power supply compartment 5. Insertion walls 501 are provided on the left and right ends of the cover 50, respectively, extending towards the inner cavity of the power supply compartment 5. Positioning protrusions 5011 are provided on the inner wall of the insertion wall 501 at the positions corresponding to the positioning grooves 531. The insertion wall 501 is inserted into the corresponding insertion gap 530 and the positioning protrusions 5011 are engaged in the corresponding positioning grooves 531, realizing a detachable connection between the cover 50 and the power supply compartment 5. The initial positioning and fixation are achieved by the cooperation of the insertion wall 501 and the insertion gap 530, and the secondary locking is achieved by the engagement of the positioning protrusions 5011 and the positioning grooves 531, ensuring the accuracy and firmness of the cover 50 installation and effectively preventing it from loosening or falling off.

[0022] In this specific embodiment, the lower end of the power supply compartment 5 is provided with a mounting cavity 54 for inserting the upper end of the light-transmitting tube 2. The upper end of the light-transmitting tube 2 is fixedly inserted into the mounting cavity 54. The structure of the insertion-type mounting cavity 54 achieves a tight and stable connection between the light-transmitting tube 2 and the power supply compartment 5. This structure ensures the coaxiality between the tube and the power supply compartment 5 and the overall structural strength, resulting in a neat product appearance and reliable connection.

[0023] In this specific embodiment, there are two light-transmitting tubes 2 arranged side by side.

[0024] In this specific embodiment, the light-transmitting tube 2 is fixedly installed in the mounting cavity 54 by adhesive. Adhesive fixing is a simple, low-cost, and effective permanent connection method. It can fully fill the gap between the tube and the mounting cavity 54, form a uniform stress distribution, and has good sealing and shock resistance, preventing the tube from loosening.

[0025] In this specific embodiment, the LED filament is supported and installed inside the light-transmitting tube 2 by a fixing bracket 8. The main body of the fixing bracket 8 is located inside the light-transmitting tube 2 and at the upper end of the light-transmitting tube 2. The fixing bracket 8 provides reliable support and positioning for the slender LED filament, ensuring that the filament is in the center of the tube and preventing it from shaking, sagging, or colliding with the tube wall during transportation and use, thus ensuring the structural stability and uniformity of light efficiency of the product.

[0026] In this specific embodiment, the main body of the fixing bracket 8 is hollow, allowing for internal wiring to connect the driver power supply 4 to the LED filament for electrical installation. This hollow wiring design cleverly conceals and protects the wires connecting the driver power supply 4 and the LED filament within the fixing bracket 8. This keeps the inner cavity of the lamp tube clean and free of exposed wires, avoiding the risk of messy wires obstructing light or aging due to high temperatures, thus improving the product's safety and aesthetics.

[0027] In this specific embodiment, the light-transmitting tube 2 is a glass tube. Glass tubes have high light transmittance, excellent optical stability (not prone to yellowing), good heat resistance and environmental friendliness. They can maximize the advantage of LED filaments emitting light from all angles, achieving the best light transmission and light distribution effect, and have a better texture than ordinary plastic tubes.
