Three, summary of the invention
The present invention seeks to develop a kind of high temperature resistant high-power LED illuminating lamp, i.e. the LED illuminating lamp that makes up with the bar shaped heat sink assembly.For better solve the radiator structure complexity, production technology is numerous and diverse and the cost technical problems of high, under particularly can the condition of trouble free service in guaranteeing the high-power LED illuminating lamp hot environment, by changing LED illuminating lamp radiator structure, reach and improve the production efficiency of making the LED illuminating lamp, less operation, reduce material and artificial cost, increase the service life, LED is the purpose of 50,000 hours light decay 30% working lives.The applicant is on the basis of original application relevant patents such as " LED road lighting lamps " simultaneously, through a large amount of tests, optimize the heat sink assembly structure more, simplify production technology, enhance productivity, make LED structure of the lighting lamp advantages of simple more, possess better radiator structure, be convenient to extensive many variety production.
The present invention's said " hot environment " is meant that LED illuminating lamp operating ambient temperature is at 40 ℃-45 ℃.
The technical solution adopted for the present invention to solve the technical problems is (in order to understand conveniently, parts label insertion of brackets among the figure): with the LED illuminating lamp of bar shaped heat sink assembly combination, by bar shaped radiator (3) assembly that has LED arranged side by side with installation component fixedly connected as a whole composition, it is characterized in that: in bar shaped radiator (3) assembly that has LED arranged side by side, each bar shaped radiator (3) is a section bar, radiation tooth is arranged, and its section is the left-right symmetry structure; Bar-shaped LED aluminium base (6) and corresponding lens (5) are adhesively fixed in the long recess below each bar shaped radiator (3).
The technical solution adopted for the present invention to solve the technical problems also comprises:
Described LED illuminating lamp with the combination of bar shaped heat sink assembly, it is characterized in that: LED aluminium base (6) is the bar-shaped LED aluminium base (6) that contains leaded pcb board, bar-shaped LED aluminium base (6) is gone up uniform LED, and each LED and single independently lens (5) are corresponding to be installed.
The described LED illuminating lamp that makes up with the bar shaped heat sink assembly is characterized in that: have bar shaped radiator (3) back arranged side by side of LED or arrange a back bar shaped radiator of installation component fixed combination LED illuminating lamp.
Described LED illuminating lamp with the combination of bar shaped heat sink assembly, it is characterized in that: after having bar shaped radiator (3) back arranged side by side or arrangement of LED, the heat radiation gap is arranged between it, and the bar shaped radiator (3) that has LED is top with the fixing LED illuminating lamp of forming one with the combination of bar shaped heat sink assembly of installation component.
Advantage of the present invention and effect:
1, owing to adopts gapped LED structure of the lighting lamp arranged side by side with the combination of bar shaped heat sink assembly, under the condition that does not reduce radiating effect, original lamp bracket and radiator are combined as an independently integrated bar shaped heat spreader structures, again this LED bar shaped radiator can be formed the assembly that assembles light fixture side by side.So improved manufacturing technology level greatly, reduced the material cost and the manufacturing process of original heat radiation disk, reduced labour intensity, improved production efficiency effectively.
2, not only be suitable for China each department and use, also suitable abroad as using under the regional hot environments such as Saudi Arabia, Arab, process patent applicant test can adapt under 40 ℃-45 ℃ environment to be used.
3, because the bar shaped radiator adopts profile structure, as 8 meters, 6 meters, 4 meters or 2 meters equal lengths is one, its length can be according to user's request or according to the model standard cutting of enterprise, change the different mould of former usefulness and made the lamp bracket of different model, significantly reduced the Mold Making cost, production technology changes and has also alleviated workman's the amount of labour, and the lamp body section bar from making, transportation, blanking, assembling LED to being mounted to road lamp, indoor lamp, Tunnel Lamp or the like illuminating lamp, become all convenient and practical behind the lamp.
Four, description of drawings
Above-mentioned each number in the figure explanation: 1. handle is installed; 2. mounting bracket; 3. radiator; 4. crossed beam trunking; 5. lens; 6.LED aluminium base (pcb board).
Five, the specific embodiment
Referring to accompanying drawing 1-Fig. 3, the present invention with the LED illuminating lamp of bar shaped heat sink assembly combination by bar shaped radiator 3 assemblies that have LED arranged side by side with installation component fixedly connected as a whole composition.Wherein in bar shaped radiator 3 assemblies that have LED arranged side by side, referring to Fig. 3, see on the section as section bar bar shaped radiator 3 that each bar shaped radiator 3 all has radiation tooth up and down, and left-right symmetry, single in other words section bar bar shaped radiator 3 sections are symmetrical structure.Bar-shaped LED aluminium base (pcb board) 6 and corresponding lens 5 are adhesively fixed in the long recess below each bar shaped radiator 3, uniform LED on the bar-shaped LED aluminium base (pcb board) 6, each LED and single independently lens 5 corresponding installations are called bar shaped radiator 3 assemblies that have LED the assembly behind the LED being installed below each bar shaped radiator 3 here.Referring to each figure, bar shaped radiator 3 or to have bar shaped radiator 3 assemblies of LED arranged side by side, between it and certain heat radiation gap arranged, dispelling the heat, the gap is changeable to be determined between the 0.5-20 millimeter according to actual conditions, certainly also can exceed this scope, this bar shaped radiator 3 assemblies that have LED arranged side by side are to be formed a whole by top mounting bracket 2 usefulness bolting, install 1 with bolting on the mounting bracket 2.Installation component is exactly by forming 1 with the bolting installation on the mounting bracket 2.
The light fixture driving power is positioned at mounting bracket 2, and light fixture driving power output connects LED by crossed beam trunking 4, bar-shaped LED aluminium base (pcb board) 6; This pcb board both as lead-in wire usefulness, can be cited approvingly the line pcb board, and simultaneously also as LED aluminium base usefulness, the LED aluminium base here is meant the assembly of even fixed L ED on the bar shaped aluminium base.
