Detailed description of the invention
Understand the technical solution of the utility model for the ease of clear, be elaborated below in conjunction with embodiment.
An embodiment of the present utility model provides the LED lamp that a kind of illumination zone is wide, as shown in Figures 1 to 3, comprises multiple light fixtures 1;
Light fixture 1 comprises frame shape substrate 101; The outside of frame shape substrate 101 is evenly distributed with multiple LED lamp pearls 102; The inside of frame shape substrate 101 is respectively arranged with two-layer heat pipe 103; Two-layer heat pipe 103 is along the axial distribution of frame shape substrate 101, and its bearing of trend is mutually vertical;
The two ends of heat pipe 103 are all connected with frame shape substrate 101, conduct to heat pipe 103 for the heat that LED lamp pearl 102 is produced; Every layer of heat pipe 103 is provided with polylith radiating fin 104 away from a side of frame shape substrate 101, and radiating fin 104 axially stretches out frame shape substrate 101 along frame shape substrate 101; The arragement direction of radiating fin 104 and bearing of trend are all perpendicular to arragement direction and the bearing of trend of 103 layers of connected heat pipes; The two ends of radiating fin 104 are all connected with frame shape substrate 101, conduct to radiating fin 104 for the heat that LED lamp pearl 102 is produced;
Multiple light fixtures 1 are along the axial arranging of frame shape substrate 101, and the arrangement mode of the radiating fin 104 of a relative side of adjacent two light fixtures 1 is identical.
LED lamp provided by the utility model, by LED lamp pearl 102 is set on frame shape substrate 101, can make light propagate towards surrounding, and illumination zone is wide.By at interior two-layer orthogonal heat pipe 103 and the radiating fin 104 of arranging of frame shape substrate 101, make each light fixture all can have two cover cooling systems, the heat that LED lamp pearl 102 produces can shift to two cover cooling systems freely by heat pipe 103 or radiating fin 104.Heat on heat pipe 103 also can be transferred on connected radiating fin 104 simultaneously.Because this two covers cooling system is mutually vertical, therefore regardless of air-flow or wind direction, all can ensure at least a set of cooling system high efficiency and heat radiation.And, no matter between heat pipe 103 or between radiating fin 104, all there is gap, therefore between two cover cooling systems, be intercommunication, a set of cooling system that radiating efficiency is lower can, by air by extremely another set of cooling system of transfer of heat, can not cause heat build-up.Therefore, LED light fixture provided by the utility model has illumination zone wide, and the high feature of radiating efficiency.
In order to form complete illuminator, meet lighting demand, conventionally need many group light fixtures 1 to be used in combination, therefore how making easily light fixture 1 link together is a very important problem.Based on this problem, preferred, adjacent two light fixtures 1 are fixedly connected with by radiating fin 104.Independent connector need not be set so again, just can realize the connection of light fixture 1.
