Abstract

The utility model relates to a light-emitting diode (LED) ceiling lamp, which comprises an LED light source, a lead, a wiring terminal, a lamp socket and a radiator. The lamp socket is composed of an installation board, a contracted cone frustum cavity, a radiating base on the back side of a small bottom of a cone frustum and a retainer ring which is arranged on the back side of the installation board and provided with a plurality of notches. The radiator is composed of a hollow cylindrical body and fins on the surface of the cylindrical body, a plurality of passages vertically penetrating through the cylindrical body are arranged on the cylindrical body, and a radiating base of the lamp socket is in threaded connection with the wall of a hollow cavity of the radiator. The space between the retainer ring of the lamp socket and the notches and the periphery of the fins of the radiator, the space between a connection lateral end face of the radiator and the back lateral side of the lamp socket and the passages vertically penetrating through the cylindrical body of the radiator form a natural ventilating passage. The LED ceiling lamp has the advantages that the natural ventilating passage is added under the condition that effective radiating surface of the ceiling lamp is not changed, thereby achieving radiation with no power consumption, reducing junction temperature of the LED lamp, prolonging service life and making breakthroughs.

Description

The LED Ceiling light

Technical field:

The present invention relates to a kind of illumination LED lamp, especially relate to a kind of LED Ceiling light.

Background technology:

LED lamp development in recent years is very rapid, by extensively on 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 smallpox furred ceiling because of receiving 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 heating from the area of dissipation that increases lamp, 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 to the prior art weak point, realizes the LED Ceiling light of idle burn-off, cooling.

The objective of the invention is to realize: a kind of LED Ceiling light through following measure; It comprises led light source, lead, binding post, lamp socket, radiator; It is characterized in that: said 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 form; Said radiator is made up of the fin of hollow column, cylinder surface; Said column body body is provided with several and connects the passage of bodies under on one's body, and said lamp socket cooling base and radiator hollow cavity wall are through being threaded; Said 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, lead one end that lead is positioned at radiator joins with binding post, lead other end break-through lamp socket cooling base is connected with led light source, and outer intermarginal space, the radiator of said 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 on one's body.

Have annular groove on the said radiator hollow cavity wall, annular groove and radiator connect the passage of body under on one's body, 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 has set up the gravity-flow ventilation passage under the constant situation of LED lamp fin efficiently radiates heat table, realized idle burn-off, reduced LED lamp junction temperature; Reduce the speed that LED light declines, thereby prolonged its service life.Can reduce about temperature rise 10 degree through the gravity-flow ventilation passage that detection the present invention sets up, obtain obvious improvement and economy and social benefit.

Description of drawings:

Fig. 1 is the example structure sketch map 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, lead 5, binding post 6, lamp socket 1, radiator 2.The LED Ceiling light is installed on the ceiling 3.Said 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, 14 of the back-up rings that the installing plate dorsal part is provided with some breach 15 and form.Said radiator 2 is made up of the fin 22 of hollow column 21, cylinder surface, and said column 21 body bodies are provided with several and connect the passage 23 of bodies under on one's body, and said lamp socket cooling base 13 and radiator hollow cavity 24 walls are through being threaded.Said 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 big absorption heat of quality is also big, so the heat that the LED lamp distributes is passed to cooling base at first rapidly.Binding post 6 is installed in radiator 2 hollow columns 21 free ends; Hollow column 21 chambeies, lead 5 one ends that lead 5 is positioned at radiator 2 join with binding post 6, lead 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, through the spring that is buckled on the back-up ring lamp socket is fixed on the ceiling.Outer intermarginal space 31, the radiator of said 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 on one's body.The present invention is provided with outside traditional fin on radiator column surface; Connect the passage of column body under on one's body in addition; Utilize " air duct pulls out wind " principle; Connect the column body on one's body the hot-air in the lower channel rise, 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 reduced the junction temperature of LED lamp effectively.

The present invention further takes following measure: have annular groove 25 on the said radiator hollow cavity wall, annular groove 25 and radiator connect the passage 23 of body under on one's body, radiator column surface channel and communicate with some fins 22 roots between the passage.From radiator connect body on one's body 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.

Combine accompanying drawing to describe embodiment of the present invention above, the structure that embodiment provides is not construed as limiting the invention, and those skilled in the art make various distortion within the scope of the appended claims or revise all in protection domain in this area.
