Description

Technical Field

[0001] This utility model relates to the field of downlight technology, and in particular to a structure for a downlight light-emitting component. Background Technology

[0002] A downlight is a type of recessed lighting fixture that shines downwards into the ceiling. It has a screw-in lamp holder that can directly mount incandescent or energy-saving bulbs. Downlights are direct light sources, projecting all light downwards. Different reflectors, lenses, blinds, and bulbs can be used to achieve various lighting effects. They are directional lighting fixtures, meaning only the area opposite the light source receives light. The beam angle is focused, resulting in concentrated light and strong contrast between light and shadow.

[0003] Downlight housings typically consist of an upper housing and a lower shade. The housing houses the light panel and power cord, while the shade houses the light guide and other components. However, existing downlight structures suffer from several drawbacks: poorly designed power cord routing for the light panel and difficulties in mounting and securing the light panel. Furthermore, they often cause glare during illumination.

[0004] Therefore, how to design a downlight light-emitting component structure that is simpler in structure, easier in wiring and layout, easier in light panel installation, and has an anti-glare effect has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to design a downlight light-emitting component structure that is simpler in structure, easier in wiring layout, easier in lamp panel installation, and has an anti-glare effect.

[0006] To achieve the above objectives, this utility model provides a downlight light-emitting component structure, including an upper lamp housing and a lamp shade connected to the lower end of the lamp housing; a light-emitting part structure is installed inside the lamp housing, the light-emitting part structure including an optical crystal at the lower end, and a light-guiding part structure is installed inside the lamp shade, the light-guiding part structure including an upper connecting cover and a lower light guide cover, wherein the upper end of the connecting cover is connected to the lower end of the optical crystal, and the lower end of the connecting cover is connected to the upper end of the light guide cover; the lamp housing has a heat-conducting mounting protrusion inside, and the lower end surface of the heat-conducting mounting protrusion forms a heat-conducting mounting surface; the light-emitting part structure also includes a lamp plate attached to the heat-conducting mounting surface, and an LED bead is provided on the lower surface of the lamp plate; the lamp plate is designed as a rectangular plate, and two wiring solder points are provided on the upper surface of one end of the lamp plate and connected to a power line, such that the distal end of the power line passes through a wire hole in the lamp housing to the outside.

[0007] In this device structure, the lamp board is directly mounted on the heat-conducting mounting surface at the lower end of the heat-conducting mounting protrusion, and the lamp board is in contact with the heat-conducting mounting surface. This allows the heat generated by the lamp board to be directly conducted to the heat-conducting mounting protrusion and the lamp housing, thereby increasing the heat dissipation area and improving the heat dissipation effect. Secondly, designing the lamp board into a rectangular structure and arranging the two wiring solder points on the upper surface of one end of the lamp board, compared with the existing structure of designing the lamp board into a square structure and arranging the two wiring solder points at two opposite corners, makes it easier to achieve electrical connection with the power cord and also makes it easier to arrange the positive and negative wires within the power cord.

[0008] As an optimization, a wiring groove is provided on the heat-conducting mounting surface at a position opposite to the wiring solder joint, so that the end of the power cord is inserted into the wiring groove.

[0009] In this way, by designing wiring channels, the ends of the power cords can be constrained and arranged, which can better avoid the impact of the power cords on the installation of the light panel.

[0010] As an optimization, several adhesive storage holes are provided on the thermally conductive mounting surface, and adhesive for bonding circuit boards is provided on the thermally conductive mounting surface to bond the lamp board to the thermally conductive mounting surface.

[0011] In this way, by designing adhesive storage holes, a certain amount of adhesive for bonding circuit boards can be stored, making the bonding of the light board more stable and reliable.

[0012] Furthermore, the adhesive storage hole is a tapered hole structure with a larger diameter at the lower end and a smaller diameter at the upper end.

[0013] This makes the structural design of the adhesive storage hole more reasonable.

[0014] Furthermore, thermally conductive silicone can be used as the adhesive for bonding circuit boards.

[0015] As an optimization, the lamp housing is designed as a rectangular box with an open bottom. A protruding post is provided at one of the corners inside the lamp housing, and the wire hole is provided on the protruding post, so that the wire hole passes through the upper surface of the lamp housing. A wire locking slot is provided on the upper surface of the lamp housing, opposite to the outer end of the wire hole, so that the outer end of the power cord can be locked into the wire locking slot.

[0016] This design simplifies and optimizes the lamp housing's structure. The protruding posts with wire holes allow for greater wire length, providing better control over the power cord. Furthermore, the included wire-clamping slots allow the power cord to be securely inserted, preventing it from interfering with the lamp's installation.

[0017] As an optimization, the heat-conducting mounting protrusion is integrally formed with the lamp housing.

[0018] This improves heat conduction and makes processing and manufacturing easier.

[0019] As an optimization, the lamp panel is made of ceramic circuit board.

[0020] In this way, the lamp board is made of ceramic circuit board, which can save on isolated power supply compared with traditional aluminum substrate, and can better adapt to both isolated and non-isolated power supplies, thereby achieving the goal of saving costs.

[0021] As an optimization, an anti-glare sheet is provided between the optical crystal and the connecting cover.

[0022] In this way, by designing an anti-glare sheet, the light can have an anti-glare effect.

[0023] As an optimization, the optical crystal is designed as a frustum-shaped structure with a smaller diameter at the top and a larger diameter at the bottom. A first light guide cavity with a blind hole structure is set in the middle of the upper surface of the optical crystal. A second light guide cavity with a tapered hole structure is set in the middle of the lower end of the optical crystal. The bottom surface of the second light guide cavity protrudes downward to form a spherical light guide surface. A stepped mounting surface is set on the inner peripheral wall of the lower end of the second light guide cavity, so that the edge of the upper surface of the anti-glare sheet is attached to the mounting stepped surface. The upper end of the connecting cover can be attached to and supported on the edge of the lower surface of the anti-glare sheet.

[0024] In this way, the structural design of the optical crystal is simpler and more reasonable, and it is also easier to install and place the anti-glare sheet.

[0025] As an optimization, the lower end of the optical crystal has a mounting flange that protrudes outwards.

[0026] This makes installation easier by setting mounting flanges on the optical crystal.

[0027] In summary, the above-mentioned device structure has the advantages of simpler structural design, easier wiring layout, easier lamp panel installation, and anti-glare effect. Attached Figure Description
