Description

Technical Field

[0001] The utility model relates to the field of lamps, in particular to a fluorescent straight tube and LED double light source lamp based on a spring-type lamp holder. Background Art

[0002] There are many types of energy-saving lamps. Currently, most energy-saving lamps are fluorescent lamps and LED lamps. Since the two energy-saving lamps have their own advantages, they each occupy a certain market. The same lamp has the functions of fluorescent lamps and light-emitting diode lamps, which can bring out the advantages of both. Among fluorescent lamps, fluorescent straight tubes have high luminous efficiency, good color rendering and light uniformity. Fluorescent straight tubes include lamp tubes and lamp holders for installing both ends of the lamp tubes. The lamp holders of fluorescent straight tubes ensure the stability and safety of fluorescent lamps, and also affect the luminous effect and service life of fluorescent lamps.

[0003] For example, an energy-saving lamp that combines a fluorescent lamp and an LED lamp (announcement number: CN202091860U, publication date: 2011-12-28), includes: a fluorescent lamp tube, an upper cover of a lamp holder, a lower cover of a lamp holder, a circuit board in the upper cover, and a connecting screw. The bottom surface of the lower cover of the lamp holder is provided with a connecting groove for an LED lamp bead board, a LED lamp bead board is provided in the connecting groove of the LED lamp bead board, the LED lamp bead board is fixedly connected to the connecting groove, LED lamp beads are provided on the LED lamp bead board, a fluorescent lamp tube is provided in the middle of the lower cover, and a power switch for controlling the LED lamp beads and the fluorescent lamp tube to light up or turn off is provided on the upper cover of the lamp holder.

[0004] This energy-saving lamp has a fluorescent lamp and an LED lamp on the same lamp, and the energy-saving mode can be selected at will by switching on and off, which is convenient to use. However, this energy-saving lamp does not use a fluorescent straight tube combined with an LED lamp. In contrast, a single-ended compact energy-saving fluorescent lamp cannot be disassembled at one end. If the fluorescent lamp is damaged, it cannot be replaced alone.

[0005] For example, a telescopic bracket lamp holder assembly (announcement number: CN201875657U, publication date: 2011-06-22) includes a bracket end cover, a spring fixing groove, a spring fixing column, and a compression spring. The lamp holder is characterized in that: there is a spring fixing groove in the bracket end cover, a lamp holder, a spring fixing end column and a compression spring on the lamp holder, and the lamp holder can freely telescope and slide in the bracket end cover.

[0006] The telescopic structure can ensure that when the fluorescent lamp tube is installed on the two telescopic lamp holders of the fluorescent lamp bracket, the lamp holder can be tightly attached to the lamp head, eliminating the gap caused by the length tolerance of the lamp tube and the length tolerance between the two lamp holders, so that the fluorescent lamp foot and the copper sheet in the lamp holder are in full and reliable electrical contact, and the contact resistance is reduced to a minimum, eliminating abnormal damage to the system caused by unreliable contact. However, the spring is arranged between the lamp holder and the fluorescent straight tube. If there is no matching limiting structure, the fluorescent straight tube and the spring may rotate, resulting in an unstable connection between the fluorescent straight tube and the lamp holder, causing the light to flicker, and even damaging the circuits and components inside the lamp holder. However, the lamp holder assembly lacks a corresponding limiting structure to limit the rotation of the fluorescent straight tube and the spring. Utility Model Content

[0025] The following is combined with Figures 1 to 5 The implementation methods of the present invention are described with relevant embodiments, but the implementation methods of the present invention are not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as the known technology in this technical field and can be known and mastered by the technicians in this technical field.

[0026] The utility model provides a fluorescent straight tube and LED dual light source lamp based on a spring-type lamp holder, such as Figure 1 and Figure 2As shown, it includes a fluorescent straight tube 1, an LED lamp group 2, a lamp housing 3 and a lamp holder 4. The fluorescent straight tube 1 and the LED lamp group 2 are respectively arranged in the lamp housing 3, and the lamp holder 4 is arranged on both sides of the lamp housing 3 along the length direction. An end cover 11 is provided at the end of the fluorescent straight tube 1, and a limiting block 111 is provided on the outer wall of the end of the end cover 11 away from the fluorescent straight tube 1, and an annular groove 112 is provided inside the end of the end cover 11 away from the fluorescent straight tube 1.

[0027] like Figure 5 As shown, the lamp holder 4 is provided with a spring 41, a cover plate 42 and a tube shell 43 integrally formed with the lamp holder 4, the cover plate 42 is provided between the lamp holder 4 and the lamp shell 3, and the tube shell 43 is provided between the cover plate 42 and the lamp holder 4. Figure 4 As shown, the cover plate 42 is provided with a lamp tube opening 421, and one end of the tube shell 43 close to the inner wall of the lamp holder 4 is provided with a protruding block 432 for fixing the spring 41, the spring 41 is arranged in the tube shell 43, and the end of the spring 41 away from the cover plate 42 is sleeved on the outside of the protruding block 432, and the end of the spring 41 close to the fluorescent straight tube 1 is arranged in the annular groove 112, and the end of the end cover 11 close to the lamp holder 4 passes through the lamp tube opening 421 and is arranged in the tube shell 43, and the tube shell 43 is provided with a limiting groove 431 matching the limiting block 111, and the wiring terminal of the fluorescent straight tube 1 passes through the end cover 11 to connect 31 electrode sheet 44.

[0028] The tube shell 43 of the lamp holder 4 of the utility model is connected 31 to the end cover 11 of the fluorescent straight tube 1 through the spring 41. The elasticity of the spring 41 can adapt to the slight size difference or installation error that may exist between the fluorescent straight tube 1 and the lamp holder 4, ensuring that the lamp tube can be firmly installed on the lamp holder 4; the elastic force of the spring 41 can ensure that the wiring terminal of the fluorescent straight tube 1 and the contact point in the lamp holder 4 always maintain close contact, avoiding poor contact due to looseness or excessive gap; the elasticity of the spring 41 can compensate for this gap change, prevent the lamp tube from loosening or being too tight due to tolerance or thermal expansion and contraction, thereby keeping the force on the lamp tube uniform and stable.

[0029] like Figure 3 As shown, the tube shell 43 and the end cover 11 are provided with matching limiting structures to prevent the fluorescent straight tube 1 from rotating, and the tube shell 43 is provided with a protruding block 432 and the end cover 11 is provided with an annular groove 112 for fixing the spring 41 to prevent the fluorescent straight tube 1 and the spring 41 from rotating, thereby causing the connection 31 between the fluorescent straight tube 1 and the lamp holder 4 to be unstable, causing the light to flicker, and may even damage the circuits and components inside the lamp holder 4.

[0030] The utility model combines a fluorescent straight tube 1 with an LED lamp. The fluorescent straight tube 1 can provide uniform and soft light and has the advantages of high luminous efficiency and low energy consumption, while the LED lamp has excellent color rendering, color reproduction ability and the advantages of high efficiency and energy saving. The advantages of the two are combined together to achieve a more efficient, flexible and energy-saving lighting effect to meet the lighting requirements of different places and needs.

[0031] The lamp holder 4 of the utility model uses a spring 41 to make it easier to insert the fluorescent tube 1 into the lamp holder 4 during installation, reducing the difficulty of installation. At the same time, when the fluorescent tube 1 needs to be replaced, the elastic force of the spring 41 also helps to easily pull out the old tube, which is convenient for maintenance operations. When the fluorescent tube 1 is damaged, it can be directly replaced without replacing the entire dual light source lamp, thereby reducing waste.

[0032] As one of the preferred embodiments of the utility model, two groups of fluorescent straight tubes 1 are provided, and the two groups of fluorescent straight tubes 1 are arranged along the width direction of the lamp housing 3. Each group of fluorescent straight tubes 1 is composed of two fluorescent straight tubes 1 arranged along the length direction. The LED lamp group 2 includes multiple LED lamps, and the multiple LED lamps are arranged between the two groups of fluorescent straight tubes 1 along the length direction of the lamp housing 3.

[0033] LED lamps are small in size, highly malleable, and can be easily designed into various shapes and sizes. In this embodiment, multiple LED lamps are arranged between two groups of fluorescent straight tubes 1 to ensure that the light is evenly distributed in the entire space and prevent the light source from being set too biased, resulting in the light source not being able to diverge evenly and dark or bright areas appearing.

[0034] As one of the preferred embodiments of the present invention, Figure 1 As shown, the end cover 11 is divided into a middle end cover and a side end cover. The end covers 11 of the two fluorescent straight tubes 1 in the same group that are close to each other are middle end covers and are electrically connected 31 through their respective middle end covers, and the end covers 11 that are away from each other are side end covers.

[0035] like Figure 2 As shown, a connection 31 is provided in the middle of the lamp housing 3, and the connection 31 is provided between two middle end covers of the same group. Two fluorescent straight tubes 1 of the same group are connected 31 through the connection 31, and the connection terminals of the two fluorescent straight tubes 1 close to each other pass through the middle end cover and are connected 31 to each other. The middle end covers are connected 31 through the connection 31, so that the fluorescent straight tubes 1 of the same group can be connected 31 together, and the side end covers are connected 31 to the lamp holder 4 through springs 41 respectively. The connection terminals of the fluorescent straight tubes 1 pass through the end covers 11 and are connected 31 to the electrode sheets 44, thereby stabilizing the connection 31 between the connection terminals and the electrode sheets 44.

[0036] As one of the preferred embodiments of the utility model, each lamp holder 4 has two tube shells 43 and each cover plate 42 has two lamp tube ports 421, the two tube shells 43 and the two lamp tube ports 421 are arranged along the width direction of the lamp housing 3, and the edge end cap, spring 41, tube shell 43 and lamp tube port 421 at the same end of the lamp holder 4 are arranged along the same central axis. The same central axis setting can make the installation process simpler and more intuitive. The user only needs to align and fix the various components in sequence according to the guidance of the central axis to quickly complete the assembly of the lamp.

[0037] As one of the preferred embodiments of the present invention, Figure 4 As shown, a side of the cover plate 42 close to the lamp holder 4 is provided with an arc-shaped protrusion 422, which is arranged outside the lamp tube opening 421, and the inner arc shape of the arc-shaped protrusion 422 fits the outer wall of the tube shell 43. The arc-shaped protrusion 422 is used to limit the movement of the tube shell 43, so that the connection 31 between the tube shell 43 and the end cover 11 is more fixed.

[0038] As one of the preferred embodiments of the present invention, Figure 4 As shown, a pair of limit blocks 111 and limit grooves 431 are provided, and the limit blocks 111 and limit grooves 431 are symmetrically distributed along the central axis of the end cover 11, and the limit grooves 431 run through the length direction of the tube shell 43. The limit blocks 111 and limit grooves 431 can limit the rotation between the tube shell 43 and the end cover 11. When disassembly is required, by pulling the fluorescent straight tube 1 toward one end, the end cover 11 of the fluorescent straight tube 1 compresses the spring 41, and the limit block 111 moves in the limit groove 431 until the other end of the fluorescent straight tube 1 leaves the lamp holder 4, and the fluorescent straight tube 1 can be disassembled.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
