Referring to fig. 1 to 4, an embodiment of the present invention discloses a lamp, which includes a light source module 100, a housing 200, and a cable assembly 300. The lamp can be a spot lamp, a down lamp, a candle lamp, etc., and the embodiment does not limit the specific type of the lamp.

The housing 200 is a basic member of the lamp, and the housing 200 can provide a mounting base and a protection function for other components of the lamp. The light source module 100 is a light emitting component of a lamp, and the light source module 100 generally includes a circuit board and a light emitting body disposed on the circuit board. Under the general condition, the luminous body can be selected as an LED lamp bead, and the LED lamp bead has the advantages of environmental protection, energy conservation, long service life and the like; of course, the present embodiment does not limit the specific type of the light emitter.

It should be understood that the housing 200 is generally provided with a light-transmitting portion, through which light emitted from the light source module 100 can be projected out of the housing 200. When the light source module 100 is used, power needs to be supplied, the cable assembly 300 is electrically connected to the light source module 100 to supply power to the light source module 100, and the cable assembly 300 can be connected to an external power source.

The cable assembly 300 includes a cable body 310 and a connector 320 extending from an outer surface of the cable body 310, wherein the cable body 310 is electrically connected to the light source module 100 to supply power to the light source module 100, and the connector 320 is used to connect the cable body 310 to the housing 200 of the lamp.

In the present embodiment, the housing 200 has a receiving cavity 210 and an opening, the opening is communicated with the receiving cavity 210, and the light source module 100 is disposed in the receiving cavity 210. In a specific installation process, the cable body 310 is inserted into the housing 200 through the opening, that is, the cable body 310 extends into the accommodating cavity 210 through the opening, so that a portion of the cable body 310 located in the accommodating cavity 210 is electrically connected to the light source module 100.

Meanwhile, the cable body 310 is fixedly connected to the housing 200 through the connector 320. Specifically, since the connector 320 extends from the outer surface of the cable body 310 and the connector 320 and the cable body 310 are integrally formed, the connector 320 and the housing 200 are fixedly connected, that is, the entire cable assembly 300 and the housing 200 are assembled, and the cable body 310 is indirectly fixed.

Generally, the cable body 310 can be fixedly connected with the inner surface of the housing 200 through the connecting member 320, and since the cable body 310 is partially located in the accommodating cavity 210, the fixed connection of the connecting member 320 with the inner surface of the housing 200 also facilitates the structural design of the connecting member 320. Of course, the present embodiment does not limit the specific connection position of the connection member 320 and the housing 200, for example, the connection member 320 may also be fixedly connected to the outer surface of the housing 200.

It should be noted that, in order to improve the processing efficiency and the convenience of assembling the lamp, the housing 200 generally includes at least two sub-housings. Specifically, the housing 200 is divided into at least two sub-housings to be processed, so that the internal structure of the housing 200 can be more conveniently molded; meanwhile, in combination with the above, the light source module 100, the cable assembly 300, and the like need to be installed in the accommodating cavity of the housing 200, and the sub-housings are easily disassembled and assembled with each other, thereby facilitating the assembly of the entire lamp.

As can be seen from the above description, in the light fixture disclosed in the embodiment of the present invention, by providing the integrally formed cable assembly 300, that is, the cable assembly 300 includes the cable body 310 and the connecting member 320 extending from the outer surface of the cable body 310, the basic power supply function of the light source module 100 is realized based on the cable body 310, and the connection between the cable body 310 and the housing 200 is realized by the connecting member 320. Compare in prior art and detain the matched stack mode through the line ball and realize the installation of cable on lamps and lanterns, the embodiment of the utility model discloses a lamps and lanterns only need to carry out once to connecting piece 320 install can, simplified installation procedure undoubtedly, promoted work efficiency.

In this embodiment, the connection member 320 and the housing 200 may be in various fitting relationships, and this embodiment is not limited thereto, for example, the two may be assembled by bonding, screwing, or the like. In one embodiment, the connector 320 is snap-fit to the housing 200, i.e., the assembly of the cable assembly 300 to the housing 200 is achieved by the snap-fit relationship of the connector 320 to the housing 200.

More specifically, the end of the connector 320 facing away from the cable body 310 may be provided with a clamping protrusion 322a, the inner surface of the housing 200 is provided with a clamping recess 220, and the clamping protrusion 322a may be clamped in the clamping recess 220. It will be appreciated that when snap-fit projections 322a are snap-fit into snap-fit recesses 220, a snap-fit relationship of connector 320 with housing 200 is achieved. Of course, the present embodiment does not limit the implementation manner of the snap-fit relationship between the connector 320 and the housing 200, and for example, the snap recess may be disposed on the connector 320, and the snap protrusion is correspondingly disposed on the inner surface of the housing 200.

Generally, the latch protrusion 322a is a protrusion, etc., and the latch recess 220 is a groove.

Since the snap-fit relationship between the snap projection 322a and the snap recess 220 is ensured, the two are pressed against each other during the snap-in process, which makes the snap-in difficult. Based on this, in an alternative solution, the side of the clamping protrusion 322a facing away from the cable body 310 may be provided with a guide chamfer for snapping into the clamping recess 220.

As shown in fig. 4, in a specific installation process, after the cable body 310 is connected to the light source module 100, the connector 320 may be pushed into the receiving cavity 210 so that the clamping protrusion 322a moves toward the clamping recess 220 until the clamping protrusion 322a moves and is clamped into the clamping recess 220; in the process, the guide chamfer can certainly reduce the pressing action of the part of the shell 200 where the clamping recess 220 is located on the clamping protrusion 322a, so that the clamping protrusion 322a can be clamped into the clamping recess 220 more easily.

In this embodiment, the specific number of the catching protrusions 322a and the catching recesses 220 is not limited, that is, one or more catching protrusions 322a may be provided on the connector 320, and one or more catching recesses 220 may be provided on the housing 200. Of course, in the embodiment where there are a plurality of catching protrusions 322a and a plurality of catching recesses 220, it is necessary to assemble a plurality of sets of catching protrusions 322a and catching recesses 220 at the time of installation to stably connect the cable assembly 300 with the housing 200.

In the existing lamp, a gap exists at the position where a cable is connected with a light source, so that sundries such as water stain and dust easily enter the light source through the connecting gap, damage is caused to the light source, and the service life of the light source is influenced; in particular, the above problems are more serious when the lamp is used in a specific environment, such as a bathroom spot lamp, where the humidity is high, when the light source is turned on and off, the temperature in the accommodating cavity is reduced from high, a pressure difference is formed between the inside of the accommodating cavity 210 and the outside of the housing 200 (i.e., a negative pressure is formed in the accommodating cavity 210), and external moisture gradually collects in the accommodating cavity and enters the light source through a gap between the cable and the light source, which may damage the light source. Meanwhile, the connection gaps of the lamp are more due to the assembly mode of the existing wire pressing buckle and the end cover plug, so that the probability of water vapor entering the interior of the lamp is greatly increased.

Based on this, in an alternative scheme, the connection member 320 may be circumferentially disposed along the circumference of the cable body 310, and the connection member 320 abuts against the inner surface of the housing 200 in the circumference thereof, and the cable assembly 300 covers the opening. Specifically, the connecting members 320 are provided in the regions between the cable body 310 and the inner surface of the housing 200, and the accommodating chamber 210 is isolated from the outside of the housing 200 by the cable assembly 300 as a whole; meanwhile, the cable body 310 and the connecting piece 320 are integrally formed, so that a connecting gap cannot exist between the cable body and the connecting piece, the number of the connecting gaps on the lamp is reduced, the probability that sundries such as water stains and dust enter the inside of the lamp is reduced, and a certain protection effect is exerted on the light source module 100.

In the present embodiment, the specific structure type of the connection member 320 is not limited, and for example, the connection member 320 may be a disk structure disposed around the cable body 310. As shown in fig. 3 and 4, in a specific embodiment, the connector 320 may include an outer extension 321 extending away from the cable body 310 and a mating portion 322 extending from a distal end of the outer extension 321.

Wherein the outward extension 321 is circumferentially arranged along the circumference of the cable body 310, that is, the outward extension 321 is arranged at a region between the cable body 310 and the inner surface of the housing 200 to isolate the receiving cavity 210 from the outside of the housing 200. The outer surface of the fitting portion 322 abuts against the inner surface of the housing 200 and the fitting portion 322 extends along the cable body 310, so that the contact area between the fitting portion 322 and the inner surface of the housing 200 is larger, and the connection stability between the connection member 320 and the housing 200 is improved. The engaging portion 322 can be provided with the aforementioned engaging protrusion 322a, and normally, the engaging protrusion 322a can be provided at the end of the engaging portion 322, but of course, the engaging protrusion 322a can also be provided at other positions of the engaging portion 322, for example, a middle position of the engaging portion 322 in the extending direction.

In the prior art, in order to improve the sealing performance inside the lamp and prevent sundries from entering the lamp from the connecting gap to damage the light source, the glue is filled at the wire outlet position in the accommodating cavity, but the glue cost is higher, the glue filling consumes more time, and the filled glue structure can also influence the heat radiation performance of the light source. Based on this, in the present embodiment, the lamp may further include a sealing member 400, and the fitting portion 322 is in sealing fit with the inner surface of the housing 200 in the circumferential direction thereof by the sealing member 400.

It is to be understood that, in a specific installation process, the sealing member 400 is installed between the fitting portion 322 and the inner surface of the housing 200 while the sealing member 400 is in a compressed state, thereby sealing a gap between the fitting portion 322 and the inner surface of the housing 200; under such a configuration, no connection gap exists between the entire cable assembly 300 and the housing 200, so that the entry of impurities into the accommodation cavity 210 is avoided; meanwhile, the glue filling by using volatile substances such as glue and the like is avoided, and the risk that the light source module 100 is corroded due to the volatilization of the glue and the like is avoided; moreover, since no glue filling process is required, the heat dissipation space of the outlet area of the light source module 100 is increased, and the heat dissipation performance of the lamp is improved.

In this embodiment, the sealing element 400 may be of various types, and may be generally selected from a silicone gasket, a foam gasket, and the like. Of course, the sealing element 400 may also be shaped other than a ring-like structure, such as a band-like structure.

In a specific embodiment, an outer surface of the fitting portion 322 may be provided with a mounting groove 322b, and the mounting groove 322b is circumferentially disposed along the fitting portion 322, and the sealing member 400 is disposed in the mounting groove 322 b. In a specific installation process, the sealing element 400 is installed in the installation groove 322b, and then the clamping protrusion 322a is clamped into the clamping recess 220, in this process, the sealing element 400 is located in the installation groove 322b and abuts against the inner surface of the housing 200, and the sealing element 400 is pressed by the matching portion 322 and the housing 200 to achieve a sealing function.

In combination with the above, during the process of clamping the clamping protrusion 322a into the clamping recess 220, due to the relative movement between the matching portion 322 and the inner surface of the housing 200, the sealing element 400 is easily out of the mounting groove 322b under the friction action of the inner surface of the housing 200, so that the sealing element 400 cannot be normally mounted. Based on this, in an alternative scheme, the matching portion 322 is provided with a limiting arm 322c at a side of the mounting groove 322b facing away from the light source module 100, the limiting arm 322c is disposed adjacent to the mounting groove 322b, and the sealing element 400 abuts against the limiting arm 322 c.

With such a configuration, when the sealing element 400 tends to run out of the mounting groove 322b under the friction action of the inner surface of the housing 200, the limiting arm 322c can limit and restrict the sealing element 400, so as to prevent the sealing element 400 from running out of the mounting groove 322b, so that the sealing element 400 can be normally mounted, and the sealing between the connecting member 320 and the inner surface of the housing 200 is ensured.

Further, in order to optimize the connection stability of the connection member 320 and the housing 200, a bearing platform 230 may be disposed at a position of the housing 200 adjacent to the opening, and the position-limiting arm 322c may overlap the bearing platform 230. It should be understood that the bearing platform 230 can support the position-limiting arm 322c and thus the connecting member 320 and the cable assembly 300; secondly, the clamping protrusion 322a and the limiting arm 322c can form a clamping structure to clamp the bearing platform 230 therebetween, so as to prevent the cable assembly 300 from being displaced.

In general, the lamp may further include a light distribution assembly 500, the light distribution assembly 500 is disposed in the accommodating cavity 210, and the light distribution assembly 500 is used for distributing light for the light source module 100. In this embodiment, the specific structure and type of the light distribution assembly 500 are not limited, for example, the light distribution assembly 500 may include a light condensing element (e.g., a reflector cup), the light condensing element is disposed corresponding to the light source module 100 and condenses the light emitted from the light source module 100, and the light distribution assembly 500 may also include a light diverging element. The light distribution assembly 500 may include a lens element, which may be used in combination with the aforementioned light collecting element or diverging element, and of course, the light collecting element or diverging element is also selected as a lens element.

In this embodiment, a mounting substrate 250 may be disposed in the receiving cavity 210, the mounting substrate 250 divides the receiving cavity 210 into a first sub-cavity 211 and a second sub-cavity 212 in the extending direction of the cable body 310, the light source module 100 is disposed in the second sub-cavity 212, the light source module 100 is mounted on the mounting substrate 250, and the cable body 310 penetrates through the mounting substrate 250 to be electrically connected to the light source module 100. It should be understood that the mounting substrate 250 undoubtedly effectively increases the usable mounting area in the receiving cavity 210, and improves the space utilization rate inside the receiving cavity 210; typically, first subchamber 211 functions as an outlet chamber, while second subchamber 212 functions as a light source chamber,

when the lamp is used, the light source module 100 generates a large amount of heat, and therefore the heat needs to be conducted to the outside of the housing 200, so as to avoid the light source module 100 from being damaged due to accumulation inside the accommodating cavity 210. Generally, the housing 200 may be provided as a heat conductor, and the heat in the receiving cavity 210 may be conducted to the outside through the housing 200. The present embodiment does not limit the specific material type of the case 200, which may be silver. A metal conductor such as aluminum.

In an alternative, the outer surface of the housing 200 may be provided with a plurality of heat dissipation fins 240. With such a configuration, the heat sink 240 can increase the contact area between the outer surface of the housing 200 and the air, thereby increasing the heat exchange amount between the housing 200 and the air to improve the heat dissipation efficiency. The plurality of heat radiating fins 240 are generally arranged along the circumferential direction of the housing 200, which can increase the number of the heat radiating fins 240.
