Detailed Description
The lighting device of the present invention will be described in detail with reference to the following embodiments and accompanying drawings.
Referring to fig. 1, in a first embodiment, the illumination lamp of the present invention mainly includes a lamp holder 10 and at least one light source module 20 assembled inside the lamp holder 10. The lighting fixture shown in fig. 1 includes six light source modules, one light source module 20 being removed for easy viewing of the fixture 10. The light source module 20 is modular, and can be arranged between two fixed tubes 11 of the lamp holder 10 in parallel, and lighting lamps with different sizes and different powers can be formed by arranging different numbers of light source modules.
For convenience of description, the light emitting direction side of the lighting fixture is defined as front/front, and the side facing away from the light emitting direction is defined as back/back.
The lamp holder 10 includes a fixing tube 11, a power supply chamber 12 fixed to one end of the fixing tube 11, an end cap 13 fixed to the other end of the fixing tube 11, and a lamp arm 14 connected to the power supply chamber 12.
The power cavity 12 is used for accommodating a power module 30 electrically connected to the light source module 20. The power supply chamber 12 includes a chamber body 121 having an opening 1211 through which the power supply module 30 can pass, and a power supply chamber cover 122 for closing the opening 1211. In this embodiment, referring to fig. 2 to 6, the cavity is made of aluminum alloy, is substantially rectangular and tubular, and includes two sets of outer walls disposed opposite to each other and a first fixing plate 1214 connected between the two sets of outer walls 1212 and 1213. The cavity 121 is formed with openings 1211 at both ends, thus configuring two power supply cavity covers 122. The power supply chamber cover 122 further includes a tube portion extending toward the fixing tube 11, which is inserted into the fixing tube 11 and is fixedly coupled to the fixing tube 11 by a screw.
The first fixing plate 1214 divides the inside of the cavity into two spaces each receiving the power module 30. In this embodiment, a total of three power modules 30 are disposed in the power cavity 12, two of which are fixed on one side of the first fixing plate 1214, and the other is fixed on the other side of the first fixing plate 1214.
A slide groove 12141, 12142 is formed on both surfaces of the first fixing plate 1214 to be recessed downward from the surface thereof, respectively. The slide slots 12141, 12142 extend through the side walls of both ends of the first fastening plate 1214 (i.e., both side walls are first side walls) to form an entrance for inserting the slide slots in each side wall. The slot opening dimensions of the runners 12141, 12142 are smaller than the slot bottom dimensions, i.e. the edges of the runners cover a portion of the slot bottom, the runners being T-shaped as viewed from the opening 1211 into the cavity. The direction in which the sliding groove extends is the same as the direction in which the profile extends, i.e. parallel to the outer walls 1212, 1213, so that the power module 30 is parallel to the outer wall of the cavity after being fixed.
In this embodiment, the power module 30 is also substantially rectangular box-shaped, and one of the outer walls 31 (the first outer wall) is used as a heat conducting plate to be tightly contacted with at least a portion of the first fixing plate 1214 after the power module 30 is fixed in the power cavity 12, so as to conduct the heat generated by the power module 30 to the power cavity 12, and then radiate the heat outwards through the power cavity 12, that is, the power cavity 12 is used as a heat sink and a housing of the power module at the same time.
The power module 30 further includes two second fixing plates 32 respectively extending from two sides of the outer wall 31 to the outside, and the second fixing plates 32 and the outer wall 31 are substantially located in the same plane. It will be appreciated that the outer wall 31 may be integrally formed with the retaining plate 32, and the retaining plate 32 may also be an extension of another outer wall that is connected to the outer wall 31, or a separate component that is secured to an outer wall of the power module. Each second fixing plate 32 has a first through hole 321 formed therein, and two sides of the first through hole 321 respectively form a notch 322 penetrating the edge of the second fixing plate. It will be appreciated that through holes may be used in place of the notches 322.
The bolt 331 and the nut 332 as the fastening member 33 are fixed to the second fixing plate 32 through the first through hole 321. The bolt 331 includes a nut 3311, a polished rod 3312 having a non-threaded outer periphery extending from the center of the back surface of the nut, and a threaded rod 3313 having a threaded outer periphery extending from the end of the polished rod. The nut 332 is fitted to the screw 3313 and has a thread formed on the inner periphery thereof. Wherein the distance between the screw 3313 and the nut 3311 is equal to or slightly greater than the sum of the thicknesses of the second fixing plate 32 and the chute edge covering the bottom of the chute. Thus, when the nut is screwed to the bottom end of the screw 3313, the edge of the chute and the second fixing plate are clamped tightly, so that the outer wall 31 of the power module and the second fixing plate 32 are tightly attached to the first fixing plate 1214 of the power cavity 12, thereby ensuring good thermal conductivity.
In addition, the outer diameter of the polish rod 3312 is larger than the outer diameter of the screw 3313, and is also larger than the diameter of the first through-hole 321. The outer diameter of the screw 3313 is smaller than or equal to the size of the notches of the slide slots 12141, 12142, and the size of the nut 3311 of the bolt is larger than the size of the notches of the slide slots 12141, 12142 but is receivable in the slots of the slide slots.
When the fastening member 33 is fixed to the second fixing plate 32, the nut 3311 faces the first fixing plate 1214, and an end portion (nut) of the fastening member 33 may be regarded as protruding from the first fixing plate 1214. When assembling, the second fixing plate 32 of each power module 30 is first fixed with the fastener 33, so that the nut faces outward. Then, the power module 30 is inserted into the opening 1211 of the power cavity 12, so that the end portion (nut 3311) of the fastener 33 is inserted into the entrance of the sliding slot 12141 (or 12142), the first fixing plate 1214 and the second fixing plate 32 are tightly attached, and the nut 3311 of the bolt 331 can slide in the sliding slot by pushing the power module, and the whole power module is inserted into the opening 1211 at most.
In order to prevent the power module 30 from sliding in the power cavity 12, screws may be driven into the first fixing plate at positions corresponding to the notches 322 of the power module 30, so that the power module 30 cannot slide out of the power cavity through the opening 1211. The notch 322 may be C-shaped, so that the power module 30 can be completely positioned by inserting the screw into the notch 322 after the screw is driven.
Therefore, the power module and the power cavity can be connected in a sliding mode through the sliding groove and the matched clamping piece. At most, one or two screws are needed to realize the fastening and the limiting of the power module and the power cavity, and the assembly and the disassembly are very convenient. In addition, the cavity of the power supply cavity can be a section bar, and the manufacture is simpler and quicker. When the length of the power supply cavity needs to be changed, a die does not need to be additionally manufactured. The size of the power supply cavity cover is smaller than that of the opening arranged on the front or back of the lamp, and the number of positions needing sealing is small. And the power supply cavity cover is disposed at the side of the lamp so as to be integrally formed with the fixing tube for fixing the light source module (referring to the lamp of fig. 9, the power supply cavity cover 42 of the power supply cavity 41 is also used as the fixing tube of the light source module 20').
In addition, in order to increase the heat conductivity and strength of the first fixing plate 1214, the thickness of the first fixing plate 1214 where the slide grooves 12141, 12142 are formed is greater than the thickness of the portion where the slide grooves are not formed, and both surfaces of the first fixing plate 1214 are stepped. A portion of the outer wall 31 and the second fixing plate 32 of the power module 30 are in contact with a higher stepped surface to achieve heat conduction.
In this embodiment, the two sliding grooves 12141, 12142 are disposed opposite to each other. In the second embodiment as shown in fig. 7, the power supply cavity of the lighting fixture is different from the power supply cavity of the first embodiment mainly in that the two sliding grooves 12141 ', 12142 ' on the first fixing plate 1214 ' of the cavity 121 ' are arranged in a staggered manner on two surfaces of the first fixing plate 1214 ', so that the thickness of the portion where the two sliding grooves 12141 ', 12142 ' are arranged can be reduced.
In this embodiment, a first fixing plate 1214 is disposed in the cavity 121 of the power cavity of the lighting fixture, and in the third embodiment shown in fig. 8, the power cavity of the lighting fixture is different from the power cavity of the first embodiment mainly in that two parallel first fixing plates 1214' are disposed in the cavity 121 ", so that more power modules can be fixed.
In other embodiments, the fastening member may include only a bolt, and the first through hole may be formed with an internal thread. The bolt is directly screwed in the first through hole.
In other embodiments, the polish rod on the bolt as the retainer may be omitted, i.e., the bolt includes a threaded rod and a nut.
In other embodiments, the outer diameter of the polished rod of the bolt serving as the clamping piece can be the same as the outer diameter of the screw rod, so that the bolt can protrude from the surface of the first fixing piece as little as possible before assembly, and transportation is facilitated.
In this embodiment, the first fixing plate has two surfaces on which sliding grooves are formed. It is understood that in other embodiments, one or more parallel sliding grooves are formed on one surface of the first fixing plate, and no sliding groove is formed on the other surface.
In a modification of the second embodiment, in the fourth embodiment, as shown in fig. 10, two first through holes 321 ' may be formed in the second fixing plate 32 ' of each power module 30 ', and correspondingly, two sliding grooves 5111, 5112 for fixing the power modules are formed in one surface of the first fixing plate 511 of the power cavity 51. Only one notch 322' may be formed in each second fixing plate.
In other embodiments, the fastening member may be a member integrally formed with the second fixing plate of the power module. For example, a rectangular metal plate is bent substantially vertically from the second fixing plate, and the free end thereof is divided into two parts, which are bent toward both sides of the rectangular metal plate, respectively, so that the metal plate is T-shaped and thus can be inserted into the sliding groove to fix the power module on the first fixing plate in the power cavity.
In this embodiment, the first fixing plate is disposed in the cavity 121, and divides the space in the cavity into two parts. It is understood that in other embodiments, the first fixing plate may be one of the sidewalls of the cavity 121, so that there is only one space in the cavity for fixing the power module.
In this embodiment, the first fixing plate is disposed on the power supply cavity, and the second fixing plate is disposed on the power supply module. It is understood that in a modification of the first embodiment, the fifth embodiment, as shown in fig. 11, the first fixing plate 611 may be disposed on the power module 61, and the second fixing plate 711 may be disposed on the power cavity 71. Thus, the first fixing plate 511 formed with the sliding slot 6111 may be one of the outer walls of the power module 61, and the second fixing plate 711 may also be one of the inner walls of the power cavity 71, and the fastening member (not shown) is fixed on the first through hole 7111 of the second fixing plate 711. The power module and the power cavity can be connected together by the clamping member sliding into the sliding slot 6111 of the power module 61.
It will be appreciated that the bolt fastening above preferably uses spacers or shims, and that the faces of the spacers or shims in contact with the mounting surface preferably conform to the mounting surface, thereby increasing the strength of the connection.
It can be understood that, in the above, a waterproof rubber ring is arranged between the power supply cavity cover and the opening edge of the cavity, and all the wire holes for wiring and the fixing holes for connecting the screws formed on the outer wall of the power supply cavity are sealed by the rubber ring or the rubber plug.
While the invention has been described in conjunction with the specific embodiments set forth above, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications, and variations that fall within the spirit and scope of the appended claims.
