New description: [New technical field] [0001] This creation is about a recessed lamp structure, especially a recessed light structure that can activate the light-emitting unit of the recessed lamp to generate heat quickly. [Prior Art] [0002] According to the arrangement of the lamp, in order to prevent the setting of the cookware from damaging the aesthetics of the assembled object or the wall surface, it is necessary for the manufacturer to preliminarily set an insertion hole in the lamp assembly, and then the lamp It is embedded in the embedded hole so that the luminaire can be integrated into the environment such as the object or the wall surface, so as not to protrude from the object or the surface of the environment, forming a sudden and unsightly feeling. [0003] Referring to the third figure, the existing downlight (5) structure is mainly provided with a bowl-shaped lamp holder (5 1 ), and then the capacity of the lamp holder (5 1 ) (5) 1 1) The bottom surface is fixed to the substrate (52), and the plurality of illuminants (53) are assembled on the substrate (52), and a lamp cover (54) is disposed at one end of the lamp holder (5 1), and the lamp cover is (5 4) A light-transmitting plate (5 5) is provided, whereby when the assembly is completed, the recessed lamp (5) is installed in an embedded hole of an environment preset such as an object or a wall surface, and then, when a light source is required, The illuminant (5 3) is activated to illuminate the surrounding environment. In order to increase the brightness of the illumination, the existing recessed lamp uses a high-power illuminant (5 3), and the power is consumed by the high-power illuminator (53). High, in the process of illuminating illumination, a higher temperature is generated, and the built-in lamp (5) is configured to assemble the illuminant (53), so that the illuminator (53) and the substrate (52) are covered by a The bowl-shaped lamp holder (5 1 ) and the lamp cover (54) and the light-transmitting plate (55) which are covered in the lamp holder (51) are arranged in a nearly closed space, and therefore, the illuminant (53) is in the illumination process. Form No. A0101 produced in the middle page The high temperature of the 16-page M422631 is difficult to dissipate, so that the illuminating body (5 3), the substrate (52), and the electronic components assembled on the substrate (52) are easily burnt and damaged due to high temperature. In some cases, although the manufacturer has developed a number of heat dissipation holes on the bowl-shaped lamp holder (5 1 ), it is found that the arrangement of the heat dissipation holes cannot effectively discharge the heat energy of the illuminating body (5 3 ). In addition, Yuting is the heat that is most easily collected on the substrate (52), and it is difficult to diverge, so that the illuminator (53) and electronic parts assembled on the substrate (52) are burnt due to excessive temperature. The ruin is still frequent, and since the heat is directly transmitted to the lamp holder (5 1 ), the surface temperature of the lamp holder (5 1 ) is extremely high, and it is extremely apt to burn the user's hand when touched. [0004] Since the existing downlight (5) assembly system mounts the substrate (52) having the illuminant (53) and the electronic component in the bowl-shaped lamp holder (5 1 ), when the illuminator (5 3) When the electronic components are damaged, the lamp cover (5 4) and the light-transmitting plate (5 5 ) must be removed one by one, and then the substrate (5 2) disposed in the lamp holder (5 1 ) And the illuminator (5 3) is separated from the lamp holder (51), so it is extremely inconvenient to repair and assemble. [0005] The reason is that the present creator has in view of the fact that the existing downlight design cannot effectively dissipate the high temperature generated by the illuminating body, and the inconvenience of maintenance and assembly is due to its many years of manufacturing and design experience and knowledge in related fields. Auxiliary, and through many ingenuity, to update and research and improve the existing recessed light structure, and to create this creation. [New Content] [〇〇〇6] This creation is related to one type, and its main purpose is to provide a recessed lamp that can be used to activate the light-emitting unit of the recessed lamp to generate heat quickly.

[0012] The recessed lamp structure as described above, wherein the lamp cover is further provided with a through hole at a center thereof, and the light cover is disposed at a through hole thereof to be provided with a light transmitting plate. [0013] The recessed lamp structure as described above, wherein the light transmissive plate of the lamp cover is a diffuser plate. [0014] Thereby, using the heat sink design in contact with the light emitting unit, the high temperature generated by the operation of the light emitting unit can be conducted to the heat sink, and the heat dissipation gap formed between the layer heat dissipation plates can be absorbed by the heat dissipation plate. The heat is in contact with the outside air, and the heat of the heat sink is quickly reduced, thereby achieving the effect of the heat dissipation of the high light-emitting unit of the form number A0101, page 5/16. [0015] Furthermore, the embedded light of the present invention is arranged by the layered heat dissipation plate and the heat dissipation gap, so that the high temperature generated by the operation of the illuminator is discharged layer by layer under the conduction of the layered heat dissipation plate and the heat dissipation gap, and the most In the case of the outer fin, the heat generated by the illuminator is almost completely dissipated, and the user can be prevented from touching the surface of the recessed lamp by the embedded lamp. [0016] In addition, the light structure of the present invention is such that the two ends of the lamp holder are all set to open ends, one end is assembled with the lamp cover and the light-transmitting plate, and the other end is configured to assemble the light-emitting unit and the heat sink. According to this, when the parts such as the illuminating body are damaged due to the long-term use, the illuminating unit can be directly replaced or repaired by the other end of the lamp holder, and the lamp cover and the light-transmitting plate are not required to be separately disassembled. The substantial benefits of maintenance organization. [Embodiment] [0017] In order to make the technical means of the present invention and the effects thereof can be more completely and clearly disclosed, the following is a detailed description, please refer to the disclosed drawings and drawings: [ 0018] First, please refer to the first and second figures.

Parts, etc., and make the illuminator (3 2 Between the reflection portion (i 2) of the chamber (1 1), the illuminator (32) is a light-emitting diode; [0022] the heat sink (4) is disposed on the lamp holder (1) The chamber (worker) includes a plurality of fins (4) stacked one on another, and the fins (4) are formed with a plurality of convex portions (41) so that the heat sinks (4) formed one above the other are formed The heat dissipation gap (42) further causes a heat sink (4) to be attached to the substrate (31) of the light emitting unit (3). [0023] Accordingly, when assembling and using, please refer to the first and second figures as follows: The light-transmitting plate (2 2) and the lamp cover (2) are sequentially arranged at one end of the lamp holder (1), followed by The lamp cover (2) is locked with the lamp holder (1) so that the light transmissive plate (2 2) is sandwiched between the lamp cover (2) and the lamp holder (1), and then the light is assembled. The body (32) and the substrate (31) of the electronic component are disposed in the chamber (χi) of the lamp holder (1), and the illuminant (32) is positioned at the reflection portion of the chamber (11) ( In the second step, in turn, a plurality of fins (4) are sequentially placed in the chamber (1 1 ) of the lamp holder (1), and the first fin (4) and the substrate (3) are placed. Fitted together, with the heat sink (4) and the substrate (3 1 ) of the light-emitting unit (3), the heat sink (4) and the substrate (3 1) are locked with the lamp holder (1). Solid, and the convex portion (4 1 ) provided by the heat sink (4) is used to form a heat dissipation gap between the heat sinks (4) stacked in sequence. Form No. A0101 Page 7 of 16 [0024] M422631 (4 2) According to this, the assembly of the recessed lamp of the present invention is completed. When it is intended to be used, the recessed light of the present invention can be inserted into the wall of the object or the ceiling, and the light-emitting unit (3) can be connected with the conductive line provided in the embedded hole. When the light is illuminated, the power source is turned on to the light-emitting unit (3) of the recessed light to drive the illuminator (32) to illuminate, providing an environment surrounding the light source illumination. [0025] When the illuminant (32) emits light, high temperature is generated at the same time, and the high temperature generated by the illuminant (32) is most easily formed by the substrate (3 1) assembled with the illuminant (32). After being absorbed, the heat sink (4) assembled with the substrate (31) can provide heat conduction on the substrate (31) to effectively lower the temperature of the substrate (3 2 ) and conduct to The heat of the heat sink (4) can convect the external air in the heat dissipation gap (42) formed between the heat sink (4) and the heat sink (4) to smoothly transfer heat to the heat sink (4). Dissipated outside, and the heat is dissipated layer by layer along the heat dissipation gap (4 2 ) between the stacked fins (4). When the outermost fin (4) is discharged, the heat is almost exhausted. In this way, not only can the high temperature generated by the illuminant (32) be effectively dissipated, but also the illuminator (32) and the electronic components assembled on the substrate (3) are not damaged by high temperature, and at the same time, When the user touches the recessed light, since the temperature has been dissipated through the multi-layer heat sink (4) and the heat sink: (4 2), the recessed light is touched at this time.

In addition, when the number of the illuminators (3 2) is small, the number of the heat sinks (4) can be reduced to reduce the manufacturing cost. Accordingly, the creation system can increase or decrease the activity according to the specifications and types of the lamps to be produced. The heat sink (4), according to this, achieves the substantial benefits of assembling various specifications and types of lamps. [0027] Furthermore, when the illuminator (3 2 ) and the electronic components disposed on the substrate (3 1 ) are damaged due to long-term use, the heat sink ( 4 ) and the substrate ( 3 1 ) can be locked. When the lock is removed, the substrate (3 1 ) can be separated from the lamp holder (1 ) for repair or replacement, thereby avoiding the existing downlight for repairing or replacing the illuminator (5 3 ) The lamp cover (5 4) and the through plate (5 5) must be detached from the lamp holder (5 1 ) one by one, and the substrate (52) and the illuminant (the photo substrate (5 2) provided in the lamp holder (5 1 )) 5 3) The inconvenience of leaving the lamp holder (5 1 ), so as to achieve the effect of simple and quick maintenance and assembly.
