Background

An LED (Light Emitting Diode ) is a semiconductor electronic component that converts electrical energy into light energy. R7S is a commonly used double ended tube, widely used for commercial and outdoor lighting. Common R7S is divided into a halogen double-ended tube and a metal halogen double-ended tube, and the traditional halogen double-ended tube is gradually replaced by the LED R7S due to low light efficiency and short service life. The LED R7S is a double-end lamp tube made of LEDs. For example, the 15W LED R7S can replace a 150W halogen double-ended tube, so that a large amount of electricity can be saved. The LED R7S can be used as warm light, white light, red light, green light and other colored light, which cannot be obtained by a halogen double-ended tube, so that the application of the LED R7S can be wider.

Meanwhile, the driving module is arranged in one of the connecting pieces, and one end of the LED module is electrically connected with the lamp cap electrode through the driving module. The heat emitted by the LED module and the driving module can be rapidly emitted to the air through the connecting piece, so that the heat radiation effect of the LED lamp is improved. In addition, the LED lamp is compact in structure, the purpose of miniaturization is achieved, and the assembly process of the LED lamp is simplified.

The invention is described below in connection with specific embodiments with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of an LED lamp according to an embodiment of the present invention, and fig. 2 is an exploded structural diagram of an LED lamp according to an embodiment of the present invention.

Referring to fig. 1 and 2, an LED lamp 100 according to an embodiment of the present invention includes: the lamp housing 160, the LED module 110 disposed in the lamp housing 160, the two connectors 120, the two cap electrodes 130, and the driving module 140.

The lamp shade 160 protects the LED module, two ends of the LED module 110 are respectively provided with a connecting piece 120, first ends of the two connecting pieces 120 are used for fixing the LED module 110, second ends of the two connecting pieces 120 are respectively provided with a lamp cap electrode 130, and one ends of the two lamp cap electrodes 130 are respectively electrically connected with two ends of the LED module 110.

Specifically, the two connecting pieces 120 are respectively disposed at two ends of the LED module 110, and fix the LED module 110 between the two connecting pieces 120, one ends of the two connecting pieces 120, which are far away from the LED module 110, are respectively provided with a lamp cap electrode 130, the two lamp cap electrodes 130 are respectively electrically connected with two ends of the LED module 110, and the lamp cap electrodes 130 are powered from an external power supply and provided for the LED module 110, so that power supply to the LED module 110 is realized.

Of course, the present invention is not limited thereto, and in the embodiment of the present invention, the driving module 140 is disposed in one of the connecting pieces 120, and one end of the LED module 110 is electrically connected to the lamp cap electrode 130 through the driving module 140. The connection member 120 may further be provided therein with a heat conductive paste (not shown), and the heat conductive paste may be coated on the side wall of the connection member 120.

In this way, the heat emitted by the LED module 110 and the driving module 140 can be rapidly emitted into the air through the connecting piece 120 and the heat-conducting mud, so as to improve the heat dissipation effect of the LED lamp 100. In addition, the connecting piece 120, the driving module 140, the lamp cap electrode 130 and the electrical wires are all disposed at two ends of the LED module 110, so that the LED lamp 100 has a compact structure, the purpose of miniaturization can be achieved, and the assembly process of the LED lamp 100 is simplified.

It should be noted that, the connecting piece 120 may be a cylindrical tube, a rectangular tube, a conical tube or a tube with a central through hole, and in this embodiment, the connecting piece 120 is opened toward one end of the lamp cap electrode 130, the opening section may be a round surface or an oval surface, a receiving cavity formed by the connecting piece 120 is used for placing the driving module 140 and/or the wire feeding, the other end of the connecting piece 120 is a semi-closed surface, and the opening on the semi-closed surface is used for extending the wire feeding to be electrically connected with the LED module 110. The present embodiment does not limit the shape of the connection member 120.

The connecting member 120 may be made of heat dissipating plastic, ceramic or metal, and the material of the connecting member 120 is not limited in this embodiment.

With continued reference to fig. 2, in order to achieve the purpose of fixing the LED module 110 and reducing parts, in some embodiments of the present invention, one end of the connecting member 120 is open, i.e. open towards one end of the lamp cap electrode 130, and the other end of the connecting member 120 has a fixing surface 121, i.e. one end towards the LED module 110 is provided with a fixing surface 121, and two ends of the LED module 110 respectively abut against the fixing surface 121 to achieve fixing, or a mounting position is provided on the fixing surface 121, and the mounting position is used for fixing the LED module 110 to achieve fixing of the LED module 110. By the method of abutting or mounting the position clamping LED module 110, parts for fixing the LED module 110 can be reduced, or some assembly procedures such as welding and the like can be omitted, the cost can be saved, the structure can be further miniaturized, and miniaturization and light weight can be realized.

Fig. 3 is a cross-sectional view of an LED lamp according to an embodiment of the present invention, and referring to fig. 3, in some embodiments of the present invention, an LED module 110 may be a double-sided module, and the double-sided module may include: a substrate 111, an LED chip disposed on the substrate 111, and an encapsulation material covering the LED chip.

One end of the base plate 111 is fixed on one of the mounting positions and is electrically connected to the driving module 140, and the other end of the base plate 111 is fixed on the other mounting position and is electrically connected to the lamp head electrode 130.

It is easy to understand that the LED chips are disposed on both sides of the substrate 111, so that 360 ° light emission can be realized, and the substrate 111 is small in size, so that the LED lamp 100 can be more miniaturized and light-weighted.

The LED module 110 may be loosened due to the instability of the LED module 110 between the two connectors 120, or the LED module 110 may be loosened due to the LED module 110 being unable to be snapped into the mounting position due to the mounting position being smaller than the end of the LED module 110.

In order to solve the above problem, fig. 4 is another exploded schematic view of the LED lamp according to the embodiment of the present invention. Referring to fig. 2 and 4, in some embodiments of the present invention, a single connection member 120 may be divided into two half cylinders, one end of each half cylinder having an inclined surface, the two inclined surfaces of the two half cylinders forming a fixing surface 121, and a gap 122 between the two inclined surfaces, the gap 122 forming an installation site. The two ends of the substrate 111 can be inserted into the slits 122 respectively.

In this way, on the one hand, the problem of loosening of the LED module 110 can be solved, and on the other hand, the installation of the driving module 140 and the like and the wiring of the wires can be facilitated. In addition, the substrate 111 can be abutted between the two fixing surfaces 121 or inserted into the gap 122, so that the LED module 110 can be fixed without using redundant components, thereby reducing the number of parts, saving the cost, and further enabling the LED lamp to be miniaturized and lighter.

For example, the cover 160 may be made of a fully transparent material to facilitate better light emission to the environment.

For example, the lampshade 160 can be made of a semitransparent material or a material with a certain transparency, so that the requirements of different use environments can be met, and in some occasions needing darker light, the material with a lower transparency can be used, so that the luminous flux of the LED light irradiated to the environment can be effectively reduced.

For another example, an incompletely transparent filter paper with a certain color may be disposed on the inner wall or the outer wall of the lampshade 160, so that the primary color light emitted by the LED module 110 can be filtered correspondingly, so as to obtain light with different colors and brightness. For example, the light-transmitting filter paper for filtering blue light is disposed on the inner wall of the lamp housing 160, so that blue light components in the light emitted from the LED module 110 can be effectively removed, and eye fatigue caused by long-time study, work and life of eyes can be reduced by removing blue light.

It should be noted that, in this embodiment, the lampshade 160 may be a cylindrical structure, a square cylindrical structure, a polygonal cylindrical structure, or the like, and may be specifically designed according to practical requirements.

In some embodiments of the present invention, it may further include: the two lamp sockets 170 are respectively arranged at one ends of the two connecting pieces 120 far away from the LED module 110, the lamp cap electrode 130 is arranged in the lamp socket 170, and at least part of the connecting pieces 120 is arranged in the lamp socket 170.

And, at least part of the connecting piece 120 can be sleeved in the lamp holder 170, and at the same time, at least part of the connecting piece 120 can be clamped in the lampshade 160, so that the whole assembly of the LED lamp 100 is realized, no additional parts are needed, and the LED lamp 100 is further miniaturized and lighter. Of course, the connecting pieces 120 may be located in the lamp holders, and the lamp cover 160 and the lamp holder 170 are connected by means of fastening, threads, welding, etc., or the lamp cover 160 is directly sleeved outside the lamp holder 170 or sleeved inside the lamp holder 170, so as to realize the integral assembly.

To make the LED lamp 100 current more stable, in some embodiments of the present invention, it may further include: the electrolytic capacitor 180, the electrolytic capacitor 180 is disposed in another connecting piece 120 except the connecting piece 120 where the driving module 140 is disposed, two ends of the electrolytic capacitor 180 are respectively electrically connected with another lamp cap electrode 130 and the LED module 110, the electrolytic capacitor 180 can absorb current when the voltage is high, reduce the output voltage, discharge when the voltage is low, and improve the output voltage, so that the current of the LED lamp 100 is more stable, and the service life of the LED lamp 100 is prolonged.

The insulating member 190 may also be made into a semi-annular structure, as shown in fig. 2, for example, since the driving module 140 and the electrolytic capacitor 180 are both connected to the lamp holder 170 to achieve fixation, the driving module 140 may be regarded as a suspended state in the connecting member 120 and not contact with the connecting member 120, and only half of the driving module 140 needs to be insulated and isolated, and electrical wires may be arranged in the accommodating cavity formed by the semi-annular insulating member 190 and the driving module 140. The parts can be further reduced, the cost is saved, and the purposes of miniaturization and light weight are achieved.
