The LED lamp combines the high-efficiency heat conduction rod of graphite base material with the heat dissipating fins, and heat quantity conducted from the high-efficiency heat conduction rod can be rapidly sent out through the heat dissipating fins, thereby reducing the temperature of the LED lamp body base material, and intensifying the dissipating effect of the LED lamp.
Description
Technical field
The utility model relates to lighting technical field, refers to a kind of LED lamp of high efficiency and heat radiation especially, belongs to lighting engineering structure field.
Background technology
LED (Light Emitting Diode), light emitting diode is a kind of solid-state semiconductor devices, it can directly be converted into light to electricity.The heart of LED is a semi-conductive wafer, and an end of wafer is attached on the support, and an end is a negative pole, and the other end connects the positive pole of power supply, makes entire wafer by epoxy encapsulation.Semiconductor wafer is made up of two parts, and a part is a P-type semiconductor, occupies an leading position in its hole, the inside, and the other end is a N-type semiconductor, mainly is electronics here.But when these two kinds of semiconductors couple together, just form a P-N knot between them.When electric current acted on this wafer by lead, electronics will be pushed to the P district, and electronics will send energy with the form of photon, the luminous principle of LED that Here it is then with hole-recombination in the P district.Led light source have use low-tension supply, power consumption less, strong, the stability height of applicability, response time weak point, environmentally safe, multicolor luminous etc. advantage, though the existing illuminating equipment costliness of price still is considered to it and will inevitably substitutes existing illuminating device.
Heat dissipation problem is the technical barrier of restriction LED lamp development always, LED lamp designers carry out balance between life of product and radiating effect, the radiating mode of LED lamp mainly contains at present: Natural Heat Convection, install fan forced heat radiation, heat pipe and loop heat pipe heat radiation etc. additional.Install fan forced heat radiation mode system complex additional, reliability is low, heat pipe and loop heat pipe radiating mode cost height, Natural Heat Convection is then emphasized the radiating effect of heat abstractor itself.General Natural Heat Convection device is illustrated in figure 1 as the fin heat radiation at present, the structure of heat abstractor changes to some extent according to the power of LED lamp, generally speaking, the higher LED lamp of power requires better radiating effect, therefore, it is very big that radiator structure tends to do, thereby influence the exquisiteness and the volume of entire product itself.Can the better LED lamp of a kind of radiating effect is provided be the technical problem that those skilled in the art press for solution.
The utility model content
The purpose of this utility model provides a kind of LED lamp of high efficiency and heat radiation, this LED lamp is used in combination the high-efficiency heat conduction rod of graphite substrate with radiating fin, the heat of coming from the conduction of high-efficiency heat conduction rod can distribute fast by radiating fin, reduce the temperature of LED lamp body base material, thereby strengthened LED lamp radiating effect.
The technical scheme that the utility model provides is as follows:
A kind of LED lamp of high efficiency and heat radiation, in lamp body substrate one side at least one LED lamp is set, the opposite side center of described lamp body substrate is provided with the high-efficiency heat conduction rod, described high-efficiency heat conduction rod be provided with radiating fin all around, the bottom of described high-efficiency heat conduction rod is provided with power interface.
Further, described LED lamp is matrix form and is arranged on the described lamp body substrate.
Further, described lamp body substrate is provided with an optical lens lampshade.
Further, described high-efficiency heat conduction rod is the graphite heat conducting rod, is provided with heat-conducting glue between described graphite heat conducting rod and the described lamp body substrate.
Further, described radiating fin is fan-shaped distribution around described high-efficiency heat conduction rod, and the length of described radiating fin shortens downwards gradually from the top of described high-efficiency heat conduction rod.
The effect of this patent is: graphite has good heat-conducting effect, heat conduction is fast and uniform and stable, therefore be used in the heat radiation of precision components inside, this patent is incorporated into graphite substrate high-efficiency heat conduction rod in the LED heat radiation, employing comes the enhance heat effect with the mode that graphite substrate high-efficiency heat conduction rod combines with radiating fin, thereby the speed of heat radiation and the uniformity are all dispelled the heat considerably beyond simple fin.Because its better heat radiating effect, so the volume of heat abstractor can be littler, brings great convenience and the space with regard to the design of giving the LED lamp like this.

The specific embodiment
Further specify the technical solution of the utility model below in conjunction with embodiment.
A kind of LED lamp of high efficiency and heat radiation, in lamp body substrate 3 one sides at least one LED lamp 2 is set, LED lamp 2 is matrix form and is arranged on the lamp body substrate 3, and lamp body substrate 3 is provided with an optical lens lampshade 1, and the light that LED lamp 2 sends can see through this optical lens lampshade 1 and throw light on.The opposite side center of lamp body substrate 3 is provided with high-efficiency heat conduction rod 5, and during actual production, the high-efficiency heat conduction rod can adopt the graphite heat conducting rod, is provided with heat-conducting glue between high-efficiency heat conduction rod 5 and the lamp body substrate 3.High-efficiency heat conduction rod 5 be provided with radiating fin 4 all around, radiating fin 4 is fan-shaped distribution around high-efficiency heat conduction rod 5, the length of radiating fin 4 shortens downwards gradually from the top of high-efficiency heat conduction rod 5, this is because the high-efficiency heat conduction rod is many more near the heat that the part of lamp body substrate 3 is conducted more, this dispels the heat with regard to the more large-area radiating fin 4 of needs, and high-efficiency heat conduction rod 5 near the part of bottom because the thermolysis on top, the heat that is transmitted to the bottom is less, only needs the radiating fin of less area just can effectively dispel the heat.The bottom of high-efficiency heat conduction rod 5 is provided with power supply 6 and power interface 7, for the LED lamp provides power supply.
Those skilled in the art will recognize that; the above-mentioned specific embodiment is exemplary; be in order to make those skilled in the art can better understand this patent content; should not be construed as is restriction to this patent protection domain; change or modify so long as disclose spiritual any being equal to of being done, all fall into this patent protection domain according to this patent.
