Description
Technical field:
The present invention relates to a kind of illuminating LED lamp, especially relate to a kind of LED Ceiling light.
Background technology:
In recent years LED lamp development is very rapid, by extensively on the products such as household electrical appliances, vehicle, computer, illumination, and especially illumination aspect, the LED lamp efficiency surpasses incandescent lamp, fluorescent lamp is the thing that points the day and await for it.Because the single chip LED luminosity is not enough, the LED lamp adopts led array formula structure usually, and LED lamp heat is concentrated thus, local temperature is too high.Be installed in Ceiling light on the furred ceiling because being subjected to the restriction of surrounding environment, the heat radiation difficulty is just more outstanding.The technical staff is for addressing this problem, the problem of trying hard to solve from the area of dissipation that increases lamp heating, and effect is also not obvious when area of dissipation increases to a certain degree after, and the heat radiation difficulty of LED lamp has restricted the LED lamp and has further developed.
Summary of the invention:
The objective of the invention is provides a kind of gravity-flow ventilation that utilizes for the prior art weak point, realizes the LED Ceiling light of powerless heat dissipating, cooling.
The objective of the invention is to realize by following measures: a kind of LED Ceiling light, it comprises led light source, wire, binding post, lamp socket, radiator, it is characterized in that: described lamp socket by installing plate, be contraction-like frustum of a cone cavity, the cooling base of frustum of a cone handle dorsal part, the back-up ring that the installing plate dorsal part is provided with some breach and formed, described radiator is comprised of the fin of hollow column, cylinder surface, described column body body is provided with several and connects the passage of bodies under with it, and described lamp socket cooling base and radiator hollow cavity wall are threaded connection; Described led light source is installed in the bottom that lamp socket is contraction-like frustum of a cone cavity, binding post is installed in radiator hollow column free end, hollow columnar body cavity, wire one end that wire is positioned at radiator joins with binding post, wire other end break-through lamp socket cooling base is connected with led light source, and outer intermarginal space, the radiator of described lamp socket back-up ring and breach and radiator fins is connected space between side end face and lamp socket dorsal part, the radiator perforation body passage formation gravity-flow ventilation passage under with it.
Have annular groove on the described radiator hollow cavity wall, annular groove and radiator connect the passage of body under with it, radiator column surface channel and communicate with some fin roots between the passage.
Compared with prior art, the LED Ceiling light that has adopted the present invention to propose, have following advantage: the present invention is in the constant situation of LED lamp fin efficiently radiates heat table, set up the gravity-flow ventilation passage, realize powerless heat dissipating, reduced LED lamp junction temperature, reduce the speed that LED light declines, thereby prolonged its service life.The gravity-flow ventilation passage set up of the present invention can reduce about temperature rise 10 degree after testing, has obtained significant progress and economy and social benefit.
Description of drawings:
Fig. 1 is the example structure schematic diagram that the present invention proposes.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment is elaborated: in one embodiment of the present of invention shown in Figure 1.Among the figure, a kind of LED Ceiling light, it comprises: led light source 4, wire 5, binding post 6, lamp socket 1, radiator 2.The LED Ceiling light is installed on the ceiling 3.Described lamp socket by installing plate 11, be contraction-like frustum of a cone cavity 12, the cooling base 13 of frustum of a cone handle dorsal part, the back-up ring 14 that the installing plate dorsal part is provided with some breach 15 and formed.Described radiator 2 is comprised of the fin 22 of hollow column 21, cylinder surface, and described column 21 body bodies are provided with several and connect bodies lower passage 23 with it, and described lamp socket cooling base 13 and radiator hollow cavity 24 walls are threaded connection.Described led light source 4 is installed in the bottom that lamp socket 1 is contraction-like frustum of a cone cavity 12, the back of led light source 4 is cooling bases 13 of frustum of a cone handle dorsal part, because cooling base is abundant, the large absorbing heat of quality is also large, so the heat that the LED lamp distributes is passed at first rapidly cooling base.Binding post 6 is installed in radiator 2 hollow columns 21 free ends, hollow column 21 chambeies, wire 5 one ends that wire 5 is positioned at radiator 2 join with binding post 6, wire 5 other end break-through lamp socket cooling bases 13 are connected with led light source, the installing plate of lamp socket is fitted on the ceiling during installation, the back-up ring of lamp socket passes ceiling, by the spring that is buckled on the back-up ring lamp socket is fixed on the ceiling.Outer intermarginal space 31, the radiator of described lamp socket back-up ring and breach and radiator fins is connected space 32 between side end face and lamp socket dorsal part, the radiator perforation body passage 23 formation gravity-flow ventilation passages under with it.The present invention is provided with outside traditional fin on radiator column surface, connect in addition the passage of column body under with it, utilize " air duct pulls out wind " principle, connect the column body interior hot air rising of lower channel with it, the outer cold air of the lamp space that intermarginal space, radiator is connected between side end face and lamp socket dorsal part outside lamp socket back-up ring and breach and radiator fins is constantly additional, has effectively reduced the junction temperature of LED lamp.
The present invention further takes following measure: have annular groove 25 on the described radiator hollow cavity wall, annular groove 25 and radiator connect the passage 23 of body under with it, radiator column surface channel and communicate with some fins 22 roots between the passage.From radiator connect body with it the air-flow that comes of lower channel withdrawing fold into the radiator hollow cavity through groove, take away the hot gas of radiator hollow cavity, the heat that promotes the temperature rise of LED lamp to produce dissipates fast.
The above has described embodiments of the present invention by reference to the accompanying drawings, and the structure that embodiment provides is not construed as limiting the invention, and those skilled in the art make within the scope of the appended claims various distortion or revise all in protection domain in this area.
