New Description: [New Technology Field] This creation is about a power conversion module for a luminaire, especially a power conversion module that allows the luminaire device to be used by the user to replace the lamp. [Prior Art] Since the light-emitting diode (LED) is in the solid-state operation mode, unlike the conventional fluorescent tube or incandescent bulb, it will not be damaged by gas or vacuum tube, and has better vibration resistance, vibration, and wear resistance. The nature of the LEDs can effectively increase the lifespan; the field of high-brightness LEDs is constantly being developed in the light of the value of LED products. In the lighting market, flashlights, searchlights, camping lights, flashlights, Medical instrument lighting, even in outdoor lighting applications, high-brightness LEDs are rapidly eroding the traditional fluorescent tube or incandescent bulb market. As shown in the first figure, it is a light-emitting diode lamp for replacing a conventional incandescent light bulb. Similar conventional light-emitting diode lamps are provided with a lamp head 2 and a light-emitting diode 1 as light-emitting elements. In addition to the power connector 3, in order to be directly screwed to the lamp holder of the conventional bulb, a power converter β 4 is built in, and the power converter 4 supplies the power required for the operation of the lamp cap 2. - However, such a structural design does not allow the user to replace the lamp cap 2 or the power converter 4 in the event of a fault, but must be discarded together with the power converter 4 and the lamp cap 2, which will not only increase the replacement of new products. The cost, invisible, has caused excessive waste of raw materials and increased waste burden. .1 \ [New Content] In view of this, the main purpose of this creation is to provide a power conversion module that enables the light-emitting diode M351981 lighting device to be used by the user to replace the lamp. In order to achieve the above, the power conversion module of the present invention comprises a casing, a power connector disposed at an end of the casing, and a power conversion circuit constructed inside the casing; wherein the casing has an open end For the other lamp holder, the power conversion circuit is provided with a coupling structure at a position facing the open end of the housing, and the overall power conversion module is electrically connected with the light-emitting element inside the lamp cap by the coupling structure, and the power conversion circuit thereof The power supply connector is connected to the external power supply circuit, and the power supply required for the operation of the lamp head is supplied through the coupling structure, thereby obtaining a power conversion module that enables the lamp device to be replaced by the lamp. One of the functions of this creation is that the overall power conversion module and the attached lamp head have pluggable characteristics, which can be used by consumers to match different lamp holders, and the applicability of the power source conversion module is increased. The second effect of this creation is that the overall power conversion module and the connected lamp cap have pluggable characteristics, so when the lamp fails, the consumer only needs to replace the faulty lamp head or the faulty power conversion module, so Reduce the cost of purchasing new products. The third effect of this creation is that the overall power conversion module and the connected lamp head have pluggable characteristics, so when the lamp fails, the consumer only needs to replace the faulty lamp head or the faulty power conversion module. Therefore, it can avoid wasting excessive waste of raw materials and can reduce the burden of garbage. [Embodiment] The characteristics of this creation can be clearly understood by referring to the detailed description of the drawings and the examples. As shown in the second and third figures, the power conversion module 10 of the present invention includes: a housing 11, a power connector 12, and a power conversion circuit 13; 6 M351981 where: the housing u is The whole electric__ group is provided with a power connector 12 and a mechanical structure main body of the electric circuit, which has an open end (1) for being combined with the main body 2, and is provided with a lamp cap at the open end (1). The body structure 112 of the body 2 is fixed, and the fastening structure 112 may be formed by at least one groove provided around the open end in. The power connector 12 is disposed on the housing U corresponding to the open end (1) and is coupled to the lamp socket (not shown); the power conversion circuit 13 is electrically connected to the power connector 12, and is in the opposite direction. The end of the housing 1 is provided with a structure 131 for electrically connecting with a light-emitting π piece 21 (for example, a light-emitting diode) inside the base 2 (). According to the simple plug-in assembly method, another lamp body 2〇 main body is inserted into the open end (1) of the casing u of the power conversion module 1G, and the structure can be constructed. When the whole lamp is used, the power conversion mode is utilized. The switch 12 is connected to the lamp socket, so that the internal circuit 13 of the power conversion module 1 is connected to the external power circuit, and then the power supply circuit and the coupling structure 131 of the power supply circuit 13 are used to supply the power required for the operation of the lamp unit 2 . - 'The power of this (4) _ change module 1G and the characteristics of the plugged and unplugged' so the consumer can as in the fourth and fifth figures == the applicability of the power source conversion module 10; and, when the luminaire fails吏Use Lu = need to replace the faulty lamp head or the faulty power conversion module, so the cost of the new product can be greatly reduced, and the excessive burden of raw materials of the wave can be avoided. From the liberation of the implementation, the shell u in this creation can be made of plastic and insulating materials, and the knees _〗! q收# Tao ^ special 3 is sealed by the sealing US from the power supply inside the open end 111 of the M351981 road 13 body shielding for the coupling structure 131 exposed; the configuration of the coupling structure 131 of the power conversion circuit 13 and the lamp cap The pattern of 20 is correspondingly configured, which may be a positive or negative electrode socket configuration as shown in the fourth figure, or a positive and negative electrode pin configuration as shown in the sixth figure. Similarly, the power connector 12 configuration in this creation is configured corresponding to the type of the lamp socket (not shown), which may be a screw configuration as shown in the fourth figure (eg, E14, E26, E27, etc.) ), or the pin configuration (such as the GU-10 format) as shown in Figure 7, to meet the needs of different common lighting fixtures. I In summary, this creation provides a better and feasible power conversion module for the luminaire, and submits a new patent application according to law; the technical content and technical features of the creation are as disclosed above, but those familiar with the technology may still Based on the disclosure of this creation, various substitutions and modifications are made without departing from the spirit of the creation of the case. Therefore, the scope of protection of this creation should not be limited to those disclosed in the examples, but should include various alternatives and modifications that do not depart from the present invention and are covered by the following claims.
