Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lighting, in particular to a light supplementing lamp. BACKGROUND

[0002] The existing light supplementing lamp has the problems of poor heat dissipation effect, short service life and low luminous efficiency in use. This is mainly because the light source part of the light supplementing lamp generates a large amount of heat, and the heat generated by the high-power light supplementing lamp during operation cannot be dissipated in time, which will affect the luminous efficiency of the lamp and the service life of the components. The existing design usually sets a heat sink on the base of the light source to dissipate heat by conducting heat to the heat sink. The way to improve the heat dissipation efficiency generally includes increasing the volume of the heat sink and increasing the fan heat dissipation, but both ways only increase the volume of the lamp, and do not increase the channel of the heat dissipation airflow, and the heat dissipation airflow can only carry the heat directed to the heat sink. In order to avoid affecting the light efficiency, prevent light leakage and uneven light spot phenomenon, it is not possible to set a heat dissipation airflow channel on the light emitting side of the lamp, especially the light supplementing lamp cup set outside the light emitting body is still prone to a large amount of heat accumulation, which affects the heat dissipation effect of the light supplementing lamp.

[0003] In order to solve at least one of the above problems, it is necessary to design a light supplementing lamp with good heat dissipation performance to improve its service life and luminous efficiency.

[0037] As Figures 1 to 4 Indicated, a light filling lamp, comprising: light source module 1, lampshade assembly 2 and radiator 3;

[0038] Light source module 1 includes base body 12 and the luminescent body 11 set on one side of base body 12, is equipped with the first vent hole 121 on the base body 12 in the periphery of luminescent body 11;

[0039] Radiator 3 is set on the other side of base body 12 opposite luminescent body 11, and the second vent hole 31 in communication with the outside is equipped on radiator 3;

[0040] Lampshade assembly 2 includes reflector cup 21, light transmission plate 22, buffer washer 23 and lamp cap shell 24, and the air vent 231 is equipped on buffer washer 23, buffer washer 23 is arranged between the cup mouth of reflector cup 21 and light transmission plate 22, and the first vent window 241 in communication with the outside is equipped on lamp cap shell 24, and lamp cap shell 24 has hollow cavity and opening side at both ends of cavity for accommodating reflector cup 21, buffer washer 23 and light transmission plate 22, and both opening sides of lamp cap shell 24 are fixed on radiator 3 and light transmission plate 22 respectively, and reflector cup 21 is fixed on base body 12;

[0041] The first vent hole 121 is located in reflector cup 21, and is in communication with the second vent hole 31, the air vent 231 and the first vent window 241 to form the first heat dissipation air duct 5.

[0042] The first heat dissipation air duct 5 is arranged to communicate the heat sink 3, the light source module 1 and the lampshade assembly 2, so that the air in the light cup 21 of the lampshade assembly is communicated with the outside air, the heat generated by the light emitter 11 in the light cup 21 is discharged to the outside, the channel of the heat dissipation air is optimized, and the heat dissipation efficiency is improved. The air vent 231 arranged on the buffer ring 23 between the light-transmitting plate 22 and the light cup 21 avoids the influence of the air flow on the light emitting effect, and simplifies the structure.

[0043] Specifically, the heat sink 3, the light source module 1 and the lamp head shell 24 are fixed to each other by screwing. The heat sink 3 can be made of a metal material with good heat conduction performance, such as copper, aluminum or copper-aluminum alloy. A fan can also be added to accelerate the flow speed of the air flow. The front surface of the light source module 1 faces the lampshade assembly 2, and the back surface faces the heat sink 3. The light emitter 11 is located at the geometric center of the front surface of the base 12, so that other components can be arranged in the area outside the light emitter 11. The base 12 is also made of a material with good heat conduction performance, and the back surface can be coated with a heat-conducting adhesive or other materials to accelerate the conduction of heat to the heat sink.

[0044] As shown in Figure 3 , the light cup 21 and the lamp head shell 24 are both hollow models with open ends. The inner wall surface of the light cup 21 has a reflective film. The upper end of the cup has a large opening, and the lower end has a small opening. The lower end surface can be fixed on the base 11 by gluing, and the light emitter 11 is covered in it, so that the light emitter 11 is located in the projection area of the light cup on the base 12. The first vent hole 121 is arranged adjacent to the edge of the light emitter 11 to ensure that the channel of the first vent hole can communicate with the space in the light cup while not affecting the installation of the light emitter and the required lower end opening diameter is small enough. The light-transmitting plate 22 can be made of plastic, glass or other organic materials that can transmit light. The smoothness and refractive index of the material can be selected according to the needs to achieve different light emitting effects, which are not limited here.

[0045] As shown in Figure 4As shown, the outer edge of the cup mouth of the reflector cup 21 has a certain thickness, or slightly extends outward in the horizontal direction, to increase the contact area with the buffer gasket 23, which is a flexible rubber ring that is not compressed and deformed, and the air vent 231 on the buffer gasket is a notch on the peripheral wall of the buffer gasket from top to bottom. The notch does not separate the buffer gasket, so it is still a whole, that is, the contact between the buffer gasket 23 and the light-transmitting plate 22 is intermittent, and the contact with the reflector cup 21 is continuous, which can ensure the buffering effect and does not affect the light emission of the cup mouth. The air vent 231 is in communication with the first ventilation window 241 on the lamp holder shell, forming an air passage between the buffer gasket 23 and the lamp holder shell 24, and simultaneously communicating the air passage between the heat sink 3 and the light source module 1 formed by the first and second ventilation holes, thereby forming a first heat dissipation air duct 5, so that the air in the reflector cup can exchange with the outside. The arrows shown in the figure are only an example of the direction of air flow, and are not a limitation on the air flow path. The heat dissipation air flow can flow from bottom to top, or from top to bottom, or have bidirectional flow at the same time.

[0046] Further, as shown in Figure 5 , the side of the buffer gasket 23 facing the cup mouth of the reflector cup 21 is the inner side, and the opposite side is the outer side, and the middle section of the inner side is recessed outward to form a clamping groove 232. When the buffer gasket 23 is clamped on the outer edge of the cup mouth of the reflector cup 21 through the clamping groove 232, the inner wall of the clamping groove 232 wraps around the outer edge of the cup mouth, and the upper side of the buffer gasket 23 faces the light-transmitting plate 22 and is tightly attached thereto. The clamping groove is used for precise positioning of the buffer gasket 23, which ensures stable fixation of the buffer gasket 23 on the reflector cup 21 and avoids accidental deviation, thereby simplifying assembly.

[0047] In some embodiments, the shape of the buffer gasket 23 is not limited, and can be flat between the reflector cup 21 and the light-transmitting plate 22, or can be clamped on the cup mouth of the reflector cup 21 by means of the clamping groove 232 structure as described above. Further, the outer diameter of the buffer gasket 23 is greater than the outer diameter of the cup mouth of the reflector cup 21, so that the outer side of the buffer gasket 23 is attached to the inner side of the lamp holder shell 24, as shown in Figures 3 to 5 , so that the buffer gasket 23 forms a buffer between the lamp holder shell 24 and the reflector cup 21, which avoids direct contact between the two and eliminates the gap, making the connection more compact, stable and frictionless.

[0048] As shown in Figures 1 to 8As shown, in some embodiments, the first vent holes 121 are provided in plurality corresponding to the second vent holes 31, or the air vents 231 are provided in plurality corresponding to the first vent windows 241, or the above-mentioned vent holes, air vents and vent windows are provided in one-to-one correspondence, and as shown in the figure, six are provided in one-to-one correspondence. In fact, the number of the above-mentioned vent holes, air vents and vent windows can be more than one as needed, and the "correspondence" refers to the consistency in quantity and position, and does not require complete alignment in shape, as long as it can ensure smooth airflow, so as to further optimize the heat dissipation air duct and ensure the smoothness of multiple heat dissipation air ducts.

[0049] As shown, Figures 1 to 8 in some embodiments, the heat sink 3 includes a heat dissipation substrate 33 and a plurality of heat dissipation fins 34 extending from the heat dissipation substrate 33. The figure only represents one form of fin, and in fact the structure of the heat dissipation fin 34 is not limited and can be arc-shaped, columnar or other. The plurality of heat dissipation fins 34 have fin spacings 35 therebetween, which can be longitudinal and transverse spacings parallel to each other as shown, Figure 6 or can be set as longitudinal / transverse single direction or curve or radial and the like according to other forms of fins. The back surface of the base body 12 is arranged on the heat dissipation substrate 33, and the second vent holes 31 are opened on the heat dissipation substrate 33 and communicate with at least part of the fin spacings 35. In fact, considering the arrangement direction and size of the second vent holes 31, they can be completely opened on the heat dissipation substrate corresponding to the fin spacings, and when the second vent holes 31 are larger or the position interferes with the heat dissipation fins 34, part of the hole openings can be blocked by the heat dissipation fins, but it does not affect the airflow. Thereby, the heat dissipation surface area is increased, and the communication design of the fin spacings 35 and the second vent holes 31 further enhances the heat dissipation capacity.

[0050] As shown, Figure 4 in some embodiments, the heat sink 3 further has third vent holes 32, the hole openings of which communicate with the outside world, similar to the second vent holes 31, which can be completely opened at a position without heat dissipation fins, or can be interfered by the heat dissipation fins. The second vent window 242 is further provided on the lamp cap shell 24, and the air outside the world can enter or leave the cavity between the lamp cap shell 24 and the reflector cup 21 through the third vent holes 32 and the second vent window 242 respectively, forming a second heat dissipation air duct 6 that communicates the inside of the lampshade assembly 2 with the outside world. Combined with the first heat dissipation air duct 5 that communicates the inside of the reflector cup with the outside world, the design of the double channels is more conducive to air convection, and at the same time, the heat inside and outside the reflector cup is taken away, so as to further improve the heat dissipation efficiency.

[0051] Further, as shown, Figures 1 to 4 and Figure 8As shown, the lamp holder shell 24 comprises a first layer shell 243 and a first layer shell 244, the first vent window 241 is located in the first layer shell 243, and the second vent window 242 is located in the first layer shell 244, the projection of the first layer shell 243 on the mounting surface of the heat sink is located in the projection of the first layer shell 244, and the outer side of the buffer gasket 23 is attached to the inner side of the first layer shell 243. Figure 4 As shown, the double-layer shell structure of the lamp holder shell 24 is in a stepped shape, and there is a transition surface between the first layer shell 243 and the first layer shell 244, which is an inclined surface inclined to the direction of the second vent window 242, which can guide the airflow, and the second vent window 242 is located on the first layer shell 244, so that the airflow flowing from below cannot directly flow out of the second vent window 242 in a straight line, and vice versa, so as to avoid flowing out too fast and not carrying enough heat. Of course, the transition surface can also be a horizontal surface, or the first layer shell 244 can also not have a transition surface, that is, the lower edge of the first layer shell 243 to the lower edge of the first layer shell 244 is a slope with a uniform slope, and the second vent window 242 is opened on the slope, which can be staggered in the longitudinal direction with the first and second vent holes below. In short, the double-layer lamp holder shell structure isolated by the buffer gasket 23 can optimize the airflow path, and the buffer gasket 23 isolates the airflow of the first and second heat dissipation air ducts 5 and 6 in the space between the reflector and the lamp holder shell, avoiding interference between the heat dissipation air ducts.

[0052] As shown in Figure 2 , Figure 8 As shown, in some embodiments, the light supplement lamp further comprises a bayonet structure 4, which is mounted on the heat sink 3 by a threaded member and is used to connect light supplement lamp accessories such as a soft cover, thereby increasing the light efficiency of the light supplement lamp.

[0053] Further, the bayonet structure 4 comprises a plurality of clamping bodies arranged at equal intervals around the outside of the lamp holder shell 24, such as Figure 2 As shown, 3 standard soft cover bayonet clamping bodies, the bayonet structure 4 and the lamp holder shell 24 have a ventilation gap. Thus, the light supplement lamp accessory can be quickly installed, and the ventilation gap design avoids the bayonet structure from blocking the heat dissipation air duct, ensuring that the heat dissipation performance is not affected.

[0054] In summary, the light supplement lamp of the present application has a more optimal airflow channel, which can improve air flow and improve the heat dissipation performance of existing light supplement lamps. In particular, the first heat dissipation air duct improves the heat accumulation environment in the reflector, improving the heat dissipation efficiency. The structure of the air vent on the buffer gasket and the arrangement of other ventilation structures all achieve structural optimization of the light supplement lamp heat dissipation system, avoiding the influence of airflow on the light output effect, reducing parts redundancy and assembly difficulty, and the design of the double air duct further enhances heat dissipation, especially improving heat dissipation on one side of the light output surface of the lamp, which is conducive to cost reduction and efficiency improvement of such products.
