The specific embodiment
For the ease of those skilled in the art's understanding, the present invention is further illustrated below in conjunction with embodiment and accompanying drawing, and the content that embodiment is mentioned not is limitation of the invention.Referring to Fig. 1 to Fig. 6, below in conjunction with accompanying drawing the present invention is described in detail.
A kind of LED Down lamp in the present embodiment, comprise photo engine module 1 and cover body 2, described photo engine module 1 comprises radiator 3, light source 4, reflection shield 5 and housing 6, described radiator 3 is connected with the upper end of light source 4, described reflection shield 5 is connected with the lower end of light source 4, and light source 4 is installed on the inner chamber of housing 6 with reflection shield 5, fixedly connected with radiator 3 in the upper end of described housing 6, described radiator 3 is provided with the heat radiation through hole 7 that is communicated with the inner chamber of housing 6, and described housing 6 is provided with some air vents 8; The outside of described housing 6 is set with fastening bar 9, and the inboard of described cover body 2 is set with the fastening groove 10 suitable with fastening bar 9, realizes snapping after fastening groove 10 rotations of described photo engine module 1 by fastening bar 9 relative cover bodies 2.
The present invention is mainly constituted by photo engine module 1 and 2 liang of big parts of cover body, and the radiator 3 of photo engine module 1 is provided with the heat radiation through hole 7 that is communicated with the inner chamber of housing 6, and housing 6 is provided with some air vents 8; Employed light source 4 is the COB-LED module in the present embodiment, because the COB-LED module can produce a large amount of heat when luminous, cause the inside and outside pressure difference of housing 6, make housing 6 inside and outside gases produce convection current, therefore a part of heat directly distributes from air vent 8 and heat radiation through hole 7, and air vent 8, inner chamber, heat radiation through hole 7 form a heat dissipation channel, are convenient to air current flow, realize cross-ventilation, good heat dissipation effect.Also have another part heat to distribute by radiator 3.Photo engine module 1 dispels the heat by heat loss through convection between the hole and two kinds of approach of radiator heat-dissipation simultaneously, the heat that can fast the COB-LED module be produced distributes, as seen the present invention has very better heat radiating effect, can prolong the service life of Down lamp effectively.Photo engine module 1 described in the present invention can assemble the light source 4 of different capacity, and can be applicable to the cover body 2 of different size and different size, has good compatibility.
In addition, when photo engine module 1 made up with cover body 2, fastening bar 7 was at first aimed at the insertion mouth of the fastening groove 10 of cover body 2, rotates photo engine module 1 then fastening bar 9 and fastening groove 10 are closely cooperated.The fastening groove 10 relative rotations of the fastening bar 9 of the present invention by the photo engine module and cover body 2 can fixed Combination, do not need to use the screw can be with the Down lamp fixed Combination with respect to prior art the present invention, do not need to closely combine by professional tool yet, combination or maintenance can be installed easily, and it is simple in structure.
In the present embodiment, described radiator 3 comprises some fin 31 and radiating bottom plate 32, one end of described fin 31 is fixedlyed connected with radiating bottom plate 32, form a heat-dissipating space between two adjacent fin 31, described heat radiation through hole 7 is arranged on the corresponding radiating bottom plate 32 of heat-dissipating space.Wherein, described radiator 3 also includes heat radiation newel 34, fixedlys connected with radiating bottom plate 32 in the lower end of described heat radiation newel 34, and described fin 31 is fixedlyed connected with the excircle of heat radiation newel 34.
Wherein, be provided with heat-conducting plate 12 between described light source 4 and the radiator 3, described heat-conducting plate 12 is fixedlyed connected with the back side of light source 4; When light source 4 is fixedlyed connected with radiator 3, described heat-conducting plate 12 and radiating bottom plate 32 butts.
When COB-LED module electrified light emitting, the heat part that it produces distributes by the through hole convection current, also has most heat to distribute by radiator 3.Heat passes to heat-conducting plate 12 from the back side of COB-LED module, and heat-conducting plate 12 is again with heat transferred fin 31, radiating bottom plate 32 and heat radiation newel 34.Because radiator 3 is provided with some fin 31, its area of dissipation is bigger, and heat is distributed rapidly, and radiator 3 can reach a good heat-radiation effect.
Wherein, described radiating bottom plate 32 is provided with some tapped through holes 33, and described housing 6 is provided with the post 11 that is spirally connected corresponding to described tapped through hole 33 places.The radiating bottom plate 32 of radiator 3 is fixedlyed connected with the post 11 that is spirally connected of housing 4 by using screw, connects fastening and is convenient to installation and maintenance.
As shown in Figure 2, be provided with at fastening bar 9 in the left side of fastening bar 9 and buckle into the fixed block that can touch clamping block 15 upper ends to fastening groove 10 processes, the fixed block lower surface touches clamping block 15, wherein clamping block 15 is little bulk, it is less to the frictional force of fixed block lower surface, can allow fastening bar 9 rotate combination smoothly.If four clamping blocks 15 are replaced as a square block, square block can produce bigger resistance to the fixed block lower surface in fastening bar 9 left sides, and especially the size at fastening bar 9 exists under the situation of error, can make fastening bar 9 can't with fastening groove 4 snappings.
Wherein, described fastening bar 9 is provided with raised line 16, and described fastening plate 14 is provided with the groove 17 suitable with raised line 16.When photo engine module 1 relative cover body 2 is done spinning movement, firmly make raised line 16 snap onto in the groove 17, make fastening bar 9 and fastening groove 10 be combined together tightly, raised line 16 stops photo engine module 1 at will not rotate, if photo engine module 1 need be split out from fastening groove 10, must firmly make raised line 16 skid off groove 17, otherwise photo engine module 1 can't split out easily from fastening groove 10.
Wherein, described cover body 2 is symmetrically installed with two spring mountings 18, described spring mountings 18 comprises a few font fixed blocks 19 and spring 20, described cover body 2 is provided with fixing strip 21 and is connected port 22, described a few font fixed block 19 inserts and connects port 22, and fixedlys connected with fixing strip 21 respectively in the left and right sides of a few font fixed blocks 19; The middle part hollow out of described a few font fixed blocks 19 forms installing space, and the both sides of installing space are respectively arranged with the jump ring piece 23 of relative distribution, and described spring 20 is arranged at installing space, and pegs graft with two jump ring pieces 23 respectively in the two ends of spring 20.
As shown in Figure 5, spring mountings 18 of the present invention is the both sides that symmetrical distribution is installed on cover body 2, when installing and using spring mountings 18, at first use tool that a few font fixed blocks 19 of middle part hollow out are one with cover body 2 fixed Combination, and then use tool to be pegged graft with two jump ring pieces 23 respectively in the two ends of spring 20.18 need of spring mountings can be installed to spring 20 combinations on the cover body 2 fast by tool, and assembly process is few, can effectively save production cost.
As shown in Figure 6, the spring of described spring 20 fixedly is provided with protective sleeve 25 in wire frame 24 tops, and the protective sleeve 25 in the present embodiment is a plastic casing; Described protective sleeve 24 is provided with for the fixing draw-in groove of wire frame 24 (not marking in the drawings) of garter spring.
Above content is preferred embodiment of the present invention only, and for those of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, this description should not be construed as limitation of the present invention.
