Description

TECHNICAL FIELD

[0001] The utility model relates to a lighting device, especially a spotlight. BACKGROUND

[0002] As a common lighting device, the spotlight is widely used in the fields of family, commercial and industrial lighting. In the structure of the existing spotlight, the light source is connected in the lamp shell, and then the lens and other light-out structures are connected in the lamp shell. At this time, the lens and the inner side of the lamp shell form a closed and small space. The heat generated by the light source during operation can only be dissipated outward through the lamp shell, which leads to poor heat dissipation effect of the light source. The insufficient heat dissipation performance easily leads to shortening of the service life of the light source and affects the lighting effect. Therefore, there is an urgent need for a spotlight with better heat dissipation effect. SUMMARY

[0003] The utility model aims at providing a spotlight to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution to the technical problem of the utility model is as follows:

[0005] A spotlight comprises a lamp shell, a lamp cup, a lens and a light source. The lamp shell is arranged to form a downward cavity. The lamp cup is located in the cavity and connected to the bottom side of the lamp shell. The lamp cup is arranged to form a light-out channel in the upward and downward directions. The lens is connected to the top side of the lamp cup and covers the light-out channel. The light source is arranged at the top of the cavity, and a heat dissipation gap is arranged between the light source and the lens.

[0006] The technical solution has at least the following beneficial effects: the light source is used to provide light. When working, the light source transmits light downward through the lens below and emits light into the light-out channel formed by the lamp cup. The light is gathered by the lamp cup and emitted outward. Since the heat dissipation gap is arranged between the light source and the lens, the heat generated by the light source can be quickly dissipated into the cavity and then dissipated outward through the lamp shell. The accumulation of heat near the light source is reduced, the working temperature of the light source is reduced, the stability and reliability of the light source are improved, the efficiency of heat dissipation of the light source is improved by using the heat dissipation gap formed between the light source and the lens, the heat dissipation performance of the spotlight is improved, the service life of the light source is prolonged, the maintenance cost and use cost are reduced, and the lighting effect is improved. In addition, the good heat dissipation performance is also beneficial to prevent the light source from causing brightness reduction and color temperature drift due to overheating, and ensures the lighting quality and effect of the spotlight.

[0007] As a further improvement of the above technical solution, a heat dissipation cup is connected in the lamp shell, the outer surface of the heat dissipation cup is attached to the inner wall of the cavity, and the light source is connected to the inner top surface of the heat dissipation cup. The heat dissipation cup can conduct heat more quickly and uniformly. In actual application, the heat dissipation cup and the lamp shell can be made of different materials, for example, the heat dissipation cup can be made of metal material to obtain better heat dissipation performance. In this way, the heat of the light source can be directly conducted to the heat dissipation cup and effectively dissipated through the heat dissipation cup, further enhancing the heat dissipation performance of the spotlight. Moreover, the outer surface of the heat dissipation cup is attached to the inner wall of the cavity, increasing the heat dissipation area and improving the heat conduction and dissipation efficiency, thereby further reducing the working temperature of the light source, reducing the local accumulation of heat around the light source, prolonging the service life of the light source, and improving the stability and reliability of the spotlight.

[0008] As a further improvement of the above technical solution, a heat dissipation rib is arranged on the top side of the lamp shell, and a plurality of heat dissipation ribs are arranged at intervals along the straight line direction. The arrangement of the heat dissipation rib increases the heat dissipation area of the top of the lamp shell, which helps to improve the heat dissipation efficiency. Especially in the heat concentrated area at the top of the lamp shell, the interval arrangement of the heat dissipation rib also helps to form air convection, enhancing the convective heat dissipation effect, so that the heat can be dissipated to the surrounding environment more quickly, reducing the accumulation of heat at the top of the lamp shell, reducing the temperature of the lamp shell, and further improving the heat dissipation performance of the spotlight.

[0009] As a further improvement of the above technical solution, a light outlet groove is arranged at the position opposite to the light source at the top end of the lens. The arrangement of the light outlet groove enables the lens to be closer to the light source, so that the light can pass through the lens more directly, reducing the loss and scattering of light, improving the brightness and uniformity of light, thereby improving the light outlet efficiency, while providing sufficient heat dissipation gap to ensure good heat dissipation performance, ensuring that the heat of the light source can be dissipated in time, preventing the accumulation of heat around the light source, and reducing the working temperature of the light source.

[0010] As a further improvement of the above technical solution, a connecting ring is arranged on the outer side of the bottom end of the lens, a plurality of first clamping hooks are arranged around the top end of the lamp cup, the bottom end of the lens abuts against the top end of the lamp cup, and the plurality of first clamping hooks are clamped on the outer side of the connecting ring. A plurality of first clamping hooks can surround a space for installing the lens. When installing the lens, the bottom end of the lens can be directly moved into the space to realize quick positioning, and then the lens is further pressed down so that the outer side of the connecting ring passes over the plurality of first clamping hooks, and the plurality of first clamping hooks are clamped on the outer side of the connecting ring, thereby realizing quick connection of the lens and the lamp cup. The connection between the lens and the lamp cup is firm and reliable, reducing the installation time and labor intensity, and improving the production efficiency.

[0011] As a further improvement of the above technical solution, the lamp cup comprises a flat section and an outwardly expanding section connected to the bottom end of the flat section, and the inner side wall of the flat section is provided with a light uniformizing structure, and the inner diameter of the outwardly expanding section gradually increases from top to bottom. After passing through the lens, the light first passes through the light uniformizing structure of the flat section, so that the light is uniformly distributed in the flat section, reducing the difference between the central brightness and the edge brightness of the light spot, and improving the uniformity of the lighting effect, and then the light enters the outwardly expanding section, and since the inner diameter of the outwardly expanding section gradually increases from top to bottom, the light gradually diffuses, and the glare is reduced, and the light emitting range is expanded, so that the light is uniformly emitted outward.

[0012] As a further improvement of the above technical solution, the light uniformizing structure comprises a stripe or a convex particle arranged on the inner side wall of the flat section. When the light passes through the lens and enters the flat section of the lamp cup, the stripe or the convex particle will scatter the light, so that the light is reflected and refracted in multiple directions. This scattering effect effectively disperses the light, reduces the concentration of the light, thereby reducing the difference between the central brightness and the edge brightness of the light spot. In actual application, by adjusting the shape, density and arrangement of the stripe or the convex particle, the scattering angle and intensity of the light can be better controlled, not only improving the uniformity of the light, but also reducing the glare and improving the softness of the lighting effect, thereby further improving the use experience.

[0013] As a further improvement of the above technical solution, the outer side of the outwardly expanding section is provided with a second hook, the bottom of the lamp shell is provided with a buckle hole, and the second hook is connected with the buckle hole. The second hook is arranged on the outer side of the outwardly expanding section, and the buckle hole is arranged on the bottom of the lamp shell. The mutual cooperation between the two enables the lamp cup to be accurately installed into the lamp shell and to maintain a stable position. Therefore, without using additional tools or fasteners to connect the lamp cup and the lamp shell, the assembly efficiency of the spotlight is improved, and the lamp cup will not loosen or fall off during long-term use.

[0014] As further improvement of the above technical scheme, the utility model still includes power cord, the power cord outside is provided with the joint, the joint outside is provided with the joint groove around, the joint is located on the joint groove top and forms the guide section, the guide section outside wall is from below to above to the guide section center close to the inclination, the lamp shell top side is provided with the wire hole, the lamp shell is located in the wire hole and is provided with the joint ring, the joint ring is connected in the joint groove. When connecting the power cord to the wire hole, the guide section is upwards through the wire hole, because the guide section outside wall is inclined design, the guide section top can easily enter the wire hole, and with the top pressure of joint, the guide section bottom position is elastically pressed inwards, so that the joint ring and the joint groove are matched with each other finally, when using the joint ring and the joint groove of each other clamping location, can prevent the power cord to the lamp shell or to the lamp shell inside movement, the power cord is stably positioned on the lamp shell, in addition, through the cooperation of joint ring and joint groove, water vapor can be effectively prevented from invading the lamp shell, thereby improving the overall water vapor performance.

[0015] As further improvement of the above technical scheme, the utility model still includes face ring, the face ring is connected to the bottom outside of lamp shell, the face ring outside is provided with at least two spring buckles. When installing and using the spotlight, the face ring is abutted to the bottom side of the installation surface of external equipment, for example the bottom side of the ceiling, and the spring buckle is elastically pulled upwards to abut on the top side position of the ceiling, so that the face ring is tightly fixed on the bottom side of the ceiling, realizing the installation and fixation of the lamp shell.

[0026] Reference Figures 1 to 4 A spotlight, comprising a lamp shell 100, a lamp cup 200, a lens 300 and a light source 400, wherein the lamp shell 100 is surrounded to form a downward cavity 110; the lamp cup 200 is located in the cavity 110, the lamp cup 200 is connected to the bottom side of the lamp shell 100, and the lamp cup 200 is surrounded to form a light outlet channel arranged in the up-down direction; the lens 300 is connected to the top side of the lamp cup 200, and the lens 300 covers the light outlet channel; the light source 400 is arranged at the top of the cavity 110, and a heat dissipation gap is arranged between the light source 400 and the lens 300.

[0027] As can be seen from the above, the light source 400 is used to provide light, in operation, the light source 400 transmits through the lens 300 located below it and emits light downward into the light-emitting channel formed by the lamp cup 200, and the light is gathered by the lamp cup 200 and then emitted outward, since the heat dissipation gap is provided between the light source 400 and the lens 300, the design of the heat dissipation gap enables the heat generated by the light source 400 to be dissipated more quickly into the cavity 110, and then dissipated outward through the lamp shell 100, reducing the accumulation of heat near the light source 400 and reducing the working temperature of the light source 400, thereby improving the stability and reliability of the light source 400, so as to improve the heat dissipation efficiency of the light source 400 by using the heat dissipation gap formed between the light source 400 and the lens 300, improve the heat dissipation performance of the spotlight, which is conducive to prolonging the service life of the light source 400, reducing maintenance and use costs, and improving lighting effects. In addition, good heat dissipation performance is also conducive to preventing the light source 400 from causing brightness reduction and color temperature drift due to overheating, thereby ensuring the lighting quality and effect of the spotlight.

[0028] The light source 400 can be directly installed on the inner top surface of the lamp shell 100, at this time, the heat generated by the light source 400 is directly conducted to the lamp shell 100, and then the heat is conducted to the air through the lamp shell 100. In actual production, considering the production cost, the lamp shell 100 is usually made of plastic material, and the heat generated at the local position of the light source 400 is difficult to be directly conducted outward through the lamp shell 100 made of plastic material. In order to better improve the overall heat dissipation efficiency, in the embodiment, the heat dissipation cup 120 is connected in the lamp shell 100, the outer surface of the heat dissipation cup 120 is attached to the inner wall of the cavity 110, and the light source 400 is connected to the inner top surface of the heat dissipation cup 120. Of course, the light source 400 is connected to the circuit board, and during installation, that is, the circuit board is installed on the inner top surface of the heat dissipation cup 120. The heat dissipation cup 120 can conduct heat more quickly and uniformly. In actual application, the heat dissipation cup 120 and the lamp shell 100 can be made of different materials, for example, the heat dissipation cup 120 can be made of metal material to obtain better heat dissipation performance, so that the heat of the light source 400 can be directly conducted to the heat dissipation cup 120 and effectively dissipated through the heat dissipation cup 120, further enhancing the heat dissipation performance of the spotlight, and the outer surface of the heat dissipation cup 120 is attached to the inner wall of the cavity 110, increasing the heat dissipation area and improving the heat conduction and dissipation efficiency, thereby further reducing the working temperature of the light source 400, reducing the local accumulation of heat near the light source 400, prolonging the service life of the light source 400, and improving the stability and reliability of the spotlight.

[0029] In order to further improve the heat dissipation effect of the lamp shell 100 position, in the embodiment, the top side of the lamp shell 100 is provided with a heat dissipation rib 130, which is arranged in a straight line direction. The arrangement of the heat dissipation rib 130 increases the heat dissipation area of the top of the lamp shell 100, which helps to improve the heat dissipation efficiency, especially in the heat concentrated area of the top of the lamp shell 100, the heat dissipation rib 130 arranged in the interval also helps to form air convection, enhances the convective heat dissipation effect, so that the heat can be dissipated to the surrounding environment more quickly, reduces the accumulation of heat on the top of the lamp shell 100, reduces the temperature of the lamp shell 100, and further improves the heat dissipation performance of the spotlight.

[0030] When the top end surface of the lens 300 is a plane, part of the light emitted by the light source 400 will not pass through the lens 300 and directly irradiate into the cavity 110. In order to improve the light emission efficiency, in the embodiment, the position of the top end of the lens 300 opposite to the light source 400 is provided with a light emission groove 310. The arrangement of the light emission groove 310 enables the lens 300 to be closer to the light source 400, so that the light can be emitted more directly through the lens 300, reducing the loss and scattering of light, improving the brightness and uniformity of light, thereby improving the light emission efficiency, while providing sufficient heat dissipation gap to ensure good heat dissipation performance, ensuring that the heat of the light source 400 can be dissipated in time, preventing the accumulation of heat near the light source 400, and reducing the working temperature of the light source 400.

[0031] For the connection between the lens 300 and the lamp cup 200, in the embodiment, the bottom end of the lens 300 is provided with a connecting ring 320, and the top end of the lamp cup 200 is surrounded by a plurality of first clamping hooks 220. The bottom end of the lens 300 abuts against the top end of the lamp cup 200, and a plurality of first clamping hooks 220 are clamped outside the connecting ring 320. A plurality of first clamping hooks 220 can surround the space for installing the lens 300. When installing the lens 300, the bottom end of the lens 300 can be directly moved into the space to realize quick positioning, and then the lens 300 is further pressed down, so that the connecting ring 320 outside passes through a plurality of first clamping hooks 220, and a plurality of first clamping hooks 220 are clamped outside the connecting ring 320, thereby realizing the quick connection of the lens 300 and the lamp cup 200. The connection between the lens 300 and the lamp cup 200 is firm and reliable, which reduces the installation time and labor intensity and improves the production efficiency.

[0032] Further, the lamp cup 200 comprises a flat section and an outwardly expanding section connected to the bottom end of the flat section, the inner side wall of the flat section is provided with a light uniformizing structure 210, and the inner diameter of the outwardly expanding section gradually increases from top to bottom. After passing through the lens 300, the light first passes through the light uniformizing structure 210 of the flat section, so that the light is uniformly distributed in the flat section, reducing the difference between the central brightness and the edge brightness of the light spot, and improving the uniformity of the lighting effect, and then the light enters the outwardly expanding section. Since the inner diameter of the outwardly expanding section gradually increases from top to bottom, the light gradually diffuses, reduces glare, and expands the light range, so as to realize uniform light outward.

[0033] The light uniformizing structure 210 is mainly used for scattering light to improve the uniformity of light distribution. In this embodiment, the light uniformizing structure 210 comprises stripes or convex particles arranged on the inner side wall of the flat section. When the light passes through the lens 300 and enters the flat section of the lamp cup 200, the stripes or convex particles will scatter the light, so that the light is reflected and refracted in multiple directions. This scattering effect effectively disperses the light, reduces the concentration of the light, and thus reduces the difference between the central brightness and the edge brightness of the light spot. In actual application, by adjusting the shape, density and arrangement of the stripes or convex particles, the scattering angle and intensity of the light can be better controlled, not only improving the uniformity of the light, but also reducing glare and improving the softness of the lighting effect, thereby further improving the use experience.

[0034] Further, the outer side of the outwardly expanding section is provided with a second hook 230, and the bottom of the lamp shell 100 is provided with a buckle hole, and the second hook 230 is connected with the buckle hole. The second hook 230 is arranged on the outer side of the outwardly expanding section, and the buckle hole is arranged on the bottom of the lamp shell 100. The cooperation between the two enables the lamp cup 200 to be accurately installed into the lamp shell 100 and kept in a stable position. Therefore, without using additional tools or fasteners to connect the lamp cup 200 with the lamp shell 100, the assembly efficiency of the spotlight is improved, and the lamp cup 200 will not loosen or fall off during long-term use.
