The present invention will be described in more detail below with reference to specific embodiments thereof.

As shown in fig. 1, a schematic exploded view of an LED spot lamp with an independently adjustable light emitting angle lens module according to a first embodiment of the present invention is shown, schematically showing the constituent modules of the LED spot lamp. The LED spotlight includes a lampshade 100, a lamp body 300, and a lens module 200 installed in the lamp body 300 and between the lampshade 100 and the lamp body 300. According to one or more examples, other modules and components are provided inside the lamp body 300, including, for example, an LED driver module, a light source module having an LED light source and an LED circuit board, and the like; in addition, the lamp body 300 may be further provided with a mounting bracket and a hollow inner structure to facilitate the arrangement and installation of various components therein, as shown in fig. 1, which are known to those skilled in the art and can be implemented without inventive labor, and will not be described herein.

Fig. 2 is an exploded view of the structure of the LED spot light shown in fig. 1, further schematically illustrating the composition and structure of the lens module 200 capable of independently adjusting the light emitting angle shown in fig. 1. As shown in fig. 3A, the lens module 200 can include a first adjustment bracket 210 with a retaining groove 212, a second adjustment bracket 230 with a rib, and an optically focused lens-pin sleeve assembly 220 nested between the first and second adjustment brackets 210 and 230. The first adjusting bracket 210, the lens-pin sleeve assembly 220 and the second adjusting bracket 230 are sequentially sleeved together to assemble the lens module 200 which can independently adjust the light emitting angle, as shown in fig. 1 to 5. The first and second adjusting brackets 210 and 230 are rotatable relative to each other, i.e., a user can screw the first and second adjusting brackets 210 and 230 in two opposite directions with two hands alone, thereby moving the lens-pin sleeve assembly 220 nested therebetween to translate back and forth along the central axis direction (i.e., the illumination direction) of the lamp relative to the first adjusting bracket 210, thereby achieving the effects of focusing and changing the illumination angle, as described in detail below.

Fig. 3A is an enlarged exploded schematic view of the configuration of the LED spotlight shown in fig. 2, further schematically illustrating details of the configuration of the lens module 200 that can independently adjust the light emitting angle shown in fig. 1. Fig. 3B is a schematic enlarged perspective view, taken longitudinally, of the lens module 200 after the components shown in fig. 3A are assembled together, illustrating the principal construction and concept of an embodiment in which relative helical sliding movement causes translational movement in the axial direction.

As shown in fig. 3A to 3B, a pair of limiting grooves 212 extending in the axial length direction are formed on the first adjusting bracket 210 having a hollow cylindrical shape as a whole in the diametrically opposite direction on the cylinder, and only one limiting groove 212 is completely shown in fig. 3A, but another limiting groove 212 is formed on the wall of the cylindrical tube in the diametrically opposite direction. Along the axial extension of the stop groove 212, the groove 212 may conveniently be provided with (e.g. printed) graduated markings 211, for example indicating the angle of illumination of the location, e.g. varying from 20 to 60. One or more (e.g., a pair of diametrically opposed) radially inwardly extending flanges 213 may also optionally be provided on the cylinder of the first adjustment bracket 210, as shown in fig. 3A-3B, to provide a guide and/or stop function when a user is screwing an adjustment, as described in more detail below.

On the second adjusting bracket 230, which may have a hollow cylindrical shape tapered at the same end as the whole, a plurality of spiral ribs protruding radially outward are formed on the cylindrical wall. For example, as shown in fig. 3A, a pair of spiral ribs 231 and 232 protruding radially outward are formed at diametrically opposite positions on the circumferential cylinder wall of the second adjusting bracket 230, and the pair of spiral ribs 231 and 232 have the same spiral direction but preferably have substantially the same extending height on the circumferential wall of the cylinder, that is, are arranged substantially diametrically opposite to each other. The two ribs extend in opposite directions as viewed in a direction perpendicular to fig. 3A, i.e., one rib (spiral rib 231) spirally rises along the cylindrical wall of the second adjusting bracket 230 and the opposite rib (spiral rib 232) spirally falls along the cylindrical wall of the second adjusting bracket 230, but their spiral directions are substantially the same. Between the pair of helical ribs 231 and 232, a coaxial pair of inner cylindrical wall sections 233 and 234 of smaller diameter are provided on the cylindrical wall of the second adjustment bracket 230, forming a wall section configuration similar to the radially inner side wall, as shown.

The lens-pin sleeve assembly 220, which is nested within the first and second adjustment brackets 210 and 230 after assembly, may, for example, be generally hollow frustoconically shaped at its trailing end, which may be slightly tapered, to facilitate nesting and self-assembly, although other shapes suitable for assembly are possible. An optical lens sheet (or a group of optical lens sheets) 223 may be mounted inside, for example, a hollow, generally frustum-shaped lens body 222 of the lens-pin sleeve assembly 220, a pair of pin shafts 221 radially protruding from, for example, a generally square boss 224 are provided (e.g., fixedly mounted or integrally formed) at diametrically opposite positions on the cylinder wall thereof, and a pair of interlocking pin sleeves 240 are fitted over the pair of pin shafts 221 in tight-fitting relation. Of course, it will be understood by those skilled in the art that the lens may be of any suitable configuration, for example, the lens body 222, the optical lens sheet 223 and the pin 221 may be of an integrally formed configuration, or other integrally assembled form, and the overall configuration may be of other configurations and forms other than cylindrical or hollow frustum shape, so long as it is capable of disposing the pin and the linkage member such as the linkage pin sleeve.

The pair of pins 221 and the interlocking pin bushing 240 (described below) are caught in the stopper groove 212 and radially protrude after the optical lens module 200 is assembled, and are movable in the stopper groove 212 along the axial length of the stopper groove 212 when the first and second adjusting brackets 210 and 230 are rotatably adjusted with respect to each other, thereby causing the entire lens-pin bushing assembly 220 to be translationally moved in the axial direction with respect to the first adjusting bracket 210, thereby performing adjustment of the optical angle.

Specifically, a pair of interlocking pin bosses 240 are fittingly mounted (fixedly fitted) on the pair of radially projecting pin shafts 221. The interlocking pin sleeve 240 is preferably a one-piece member including a mating hole 242, which may be polygonal (shown as hexagonal) as shown, for example, in fig. 3A-3B, and a snap groove 243 for snap retention on the angled boss 224. The hexagonal mating holes 242 of the interlocking pin bushings 240 facilitate a tight fit with the pin shaft 221, and the snap slots 243 of the interlocking pin bushings 240 snap over the bosses 224 after assembly to the pin shaft 221, thereby further facilitating a secure assembly of the interlocking pin bushings 240 with the pin shaft 221 and a reliable interlocking with the lens-pin bushing assembly 220.

It is important that the interlocking pin sleeves 240 also have sliding grooves 241, i.e., the pair of interlocking pin sleeves 240 shown in fig. 3A-3B each have an angled sliding groove 241 to receive the respective helical ribs 231 and 232 when the optical lens module 200 is assembled, it is apparent that the sliding grooves 241 are preferably angled grooves as shown in fig. 3A-3B, configured, sized and oriented to match the shape and spatial orientation of the helical ribs, to facilitate a smooth, loose fit and a relatively smooth sliding motion. When an operator screws the adjusting optical lens module 200, the sliding groove 241 may perform a spiral sliding motion with respect to the corresponding spiral ribs 231 and 232, so as to cause the pin shaft 221 fixedly assembled with the linking pin sleeve 240 to move up and down in the axial direction in the limiting groove 212, thereby driving the lens-pin sleeve assembly 220 to move up and down in the axial direction, thereby achieving adjustment of the adjusting optical angle and/or focusing of the lens.

Of course, it will be understood by those skilled in the art that the foregoing description and illustration are merely exemplary and that other configurations and technical means for achieving a secure fit of the linking pin sleeve 240 with the pin shaft 221 and a reliable linking with the lens-pin sleeve assembly 220 will occur to those skilled in the art.

The linking pin sleeve 240 may further carry an arrow mark, and the arrow mark of the linking pin sleeve 240 indicates, for example, a lighting angle at which the lens-pin sleeve assembly 220 is located when the pin shaft 221 of the lens-pin sleeve assembly 220 translates up and down in the limiting groove 212, as shown in fig. 3A-4.

As shown in fig. 3B, in addition to illustrating the sliding movement fitting relationship of the slide groove 241 of the interlocking pin sleeve 240 and the spiral ribs 231 and 232, the fitting between the flange 213 of the first adjusting bracket 210 and the undercut 235 provided at the lower end of the second adjusting bracket 230 and recessed radially inward according to an example is also illustrated. Specifically, when the operator screws and adjusts the optical lens module 200, the flange 213 may move slidably with respect to the undercut 235, serving as a guide and a stopper. Of course, it will be understood by those skilled in the art that this pair of features is optional and can be modified and replaced without affecting the implementation of the basic inventive concept of the present invention.

Fig. 4 is a schematic diagram illustrating how the independently adjustable light emitting angle lens modules 200 shown in fig. 1 to 3 are independently adjusted. As shown in fig. 4, a user, for example, a factory or engineering debugging person, respectively holds the first adjusting bracket 210 and the second adjusting bracket 230 with two hands to perform screwing adjustment actions in opposite directions, so that the spiral ribs 231 and 232 of the second adjusting bracket 230 can loosely fit into the slide grooves 241 of the corresponding interlocking pin sleeves 240 fixedly mounted on the cylinder walls of the lens-pin sleeve assemblies 220 to relatively spirally rotate and slide in the axial direction and be restricted by the limiting grooves 212 to be movable in an up-and-down translational direction, the lens-pin sleeve assemblies 220 nested therebetween are also driven to move in a translational direction relative to the second adjusting bracket 230 together with the interlocking pin sleeves 240, thereby realizing adjustment of focusing and optical angles, and displaying the optical angle values with the scales of the interlocking pin sleeves 240 and the scale marks 211 after being adjusted in position. A pair of inner cylindrical wall sections 233 and 234 provided on the cylindrical wall of the second adjusting bracket 230 can cooperate with the spiral ribs 231 and 232 to circumferentially guide and radially restrain the sliding movement of the slide groove 241 of the interlocking pin sleeve 240 relative to the spiral ribs 231 and 232 when the first adjusting bracket 210 and the second adjusting bracket 230 perform the screwing adjusting movement in opposite directions to each other. In addition, during the above-mentioned screw adjustment, the radially inner side surfaces of the inner cylinder wall sections 233 and 234 may also cooperate with and be constrained by radially outwardly projecting vertically extending ribs on the lens body 222 shown in fig. 3A to ensure a reliable and smooth sliding movement of the sliding groove 241 relative to the spiral ribs 231 and 232. As shown in fig. 3A-3B, the inner cylindrical wall sections 233 and 234 are radially inward of the helical ribs 231 and 232 and have a higher axial height than the inner circumferential wall sections of the helical ribs 231 and 232, and are preferably diametrically opposed to each other for the pin shaft 221 to pass through when assembled in place. Between the inner cylinder wall sections 233 and 234 and the corresponding helical ribs 231 and 232 (and their further circumferentially extending helical ribs) there is a circumferentially extending radial gap which may be large enough to radially accommodate the respective interlocking pin sleeve 240 and ensure smooth and reliable relative movement between the relevant components of the lens module 200 during relative helical movement. The spiral ribs 231 and 232 are located radially inward of the spiral ribs 231 and 232 as shown, and have an axial height higher than that of the spiral ribs 231 and 232. The radial dimensions of the helical ribs 231 and 232 can be designed such that the inner side of their defined cylindrical shape can nest the lens body 222 and the outer side of their defined cylindrical shape can nest the first adjustment bracket 210.

Although the inner cylinder wall segments 233 and 234 are shown as a pair (i.e., two), those skilled in the art will appreciate that the number of inner cylinder wall segments can be one or more than two, and such is within the scope of the present invention.

As shown in fig. 4, since the lens module 200 can independently adjust the light emitting angle and focus independently of the lamp body of the LED lamp, the lens module 200 can be independently adjusted manually in real time before factory, field assembly or on the field, and then mounted on the LED spot lamp and the LED spot lamp is mounted in place without adjusting and focusing the light emitting angle when or after the LED is mounted, which greatly increases the convenience of adjustment and reduces the difficulty and cost of installation, maintenance and replacement.

Fig. 5 shows a schematic view of how the lens module of fig. 4 after the adjustment is completed is assembled into an LED luminaire. As shown in fig. 5, after the adjustment of the lens module 200 is completed, the lens module 200 is mounted on the lamp body 300, and then the lamp cover 100 is mounted, so that the LED spot lamp with the adjusted light emitting angle is assembled. For example, when the light effect of the spotlight needs to be changed, the LED spotlight only needs to be taken down, and the lens modules with different light effects are adjusted or replaced. Therefore, the utility model discloses a LED lamps and lanterns with lens module that can independently adjust luminous angle, for example the LED shot-light, can directly be used for field installation, field maintenance or field replacement, greatly increased user-friendliness, reduced installation and debugging cost, improved the security and the reliability of field installation debugging even.

In the utility model, the light emitting angle of the lens module of the LED lamp (such as the LED spotlight) which can independently adjust the light emitting angle can be adjusted within the range of 10-100 degrees, preferably within the range of 18-60 degrees. For example, more preferably, it can be adjusted within the range of 18 to 36, or within the range of 20 to 46.

The utility model discloses in, applicable LED lamps and lanterns include the LED shot-light, for example, outdoor LED shot-light, especially high-power outdoor LED shot-light, courtyard LED shot-light, view illumination LED shot-light, etc.

The foregoing description of several embodiments of the invention has been presented for the purposes of illustration and description. The foregoing description is not intended to be exhaustive or to limit the invention to the precise steps and/or forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. The scope of the invention and all equivalents are intended to be defined by the appended claims.
