Description
Technical field
The utility model relates to the LED lighting field, particularly a kind of LED wick sheet and LED lamp.
Background technology
LED (Light Emitting Diode, light emitting diode) is a kind of solid-state semiconductor devices, and 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 one " P-N knot " between them.When electric current acted on this wafer through 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.And the color of light wavelength decision light, by forming the decision of P-N knot material.
Yet the heat dissipation technology of LED lamp and the structure of lamp are attractive in appearance etc. is the problem that people are studying always, and existing LED lamp radiator heat-dissipation effect is all not so good, and structure is also attractive in appearance inadequately.
Summary of the invention
The main purpose of the utility model provides a kind of LED wick sheet and LED lamp, is intended to realize saving material, reduces cost, and LED lamp radiating effect is better, through the change of LED wick chip architecture, makes outward appearance more attractive in appearance.
The utility model proposes a kind of LED wick sheet, comprises heat-conducting substrate and is arranged on several LED illuminators on the said heat-conducting substrate, and said heat-conducting substrate is a cirque structure.
Preferably, said LED illuminator surrounds at least one circumference successively.
The utility model proposes a kind of LED lamp again; Comprise radiator and at least one led chip; Said led chip comprises the heat-conducting substrate that is connected with said radiator and is arranged on several LED illuminators on the said heat-conducting substrate that said heat-conducting substrate is a cirque structure.
Preferably, said LED illuminator surrounds at least one circumference successively.
Preferably, said led chip is 2 to 5.
The LED wick sheet of the utility model is formed good looking appearance by the heat-conducting substrate of cirque structure with several LED illuminators that are arranged on the said heat-conducting substrate.The light emitting source of the LED lamp of the utility model is made up of the LED wick sheet of a plurality of annulars, is not connected mutually between the annular LED wick sheet, has saved the heat-conducting substrate material, reduces cost, and also makes heat radiation faster, and is also more attractive in appearance.
Description of drawings
Fig. 1 is the example structure sketch map of the utility model LED wick sheet;
Fig. 2 is the example structure sketch map of the utility model LED lamp.
The realization of the utility model purpose, functional characteristics and advantage will combine embodiment, further specify with reference to accompanying drawing.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to Fig. 1, an embodiment of the LED wick sheet of the utility model is proposed, this LED wick sheet 100 comprises heat-conducting substrate 101 and is arranged on several LED illuminators 102 on the said heat-conducting substrate 101.Said heat-conducting substrate 101 be one can heat conduction the PCB substrate, can be connected with power line, driving LED illuminator 102 is luminous.Said heat-conducting substrate 101 is a cirque structure, and is simple in structure, good looking appearance.The LED illuminator 102 that is arranged on the heat-conducting substrate 101 surrounds at least one circumference successively, can increase or reduce the circumference number of turns that LED illuminator 102 surrounds into according to the needs of brightness of illumination.Said LED wick sheet 100 can be connected with the radiator on the LED lamp; The heat accumulation that LED illuminator 102 produces is on said heat-conducting substrate 101; Heat-conducting substrate 101 conducts heat to said radiator, by radiator heat is exhaled, and reduces LED illuminator 102 temperature on every side.
With reference to Fig. 2, an embodiment of the LED lamp of the utility model is proposed again, said LED lamp comprises radiator 200 and at least one led chip.Said led chip comprises the heat-conducting substrate 101 that is connected with said radiator 200 and is arranged on several LED illuminators 102 on the said heat-conducting substrate 101.Said heat-conducting substrate 101 be one can heat conduction the PCB substrate, can be connected with power line, driving LED illuminator 102 is luminous.Said heat-conducting substrate 101 is a cirque structure, and is simple in structure.The LED illuminator 102 that is arranged on the said heat-conducting substrate 101 surrounds at least one circumference successively, can increase or reduce the circumference number of turns that LED illuminator 102 surrounds into according to the needs of brightness of illumination.But said heat-conducting substrate 101 heat conduction, the heat accumulation that LED illuminator 102 produces is on said heat-conducting substrate 101, and heat-conducting substrate 101 conducts heat to said radiator 200, by radiator 200 heat is exhaled, and reduces the temperature around the LED illuminator 102.
In the utility model LED lamp, said led chip is 2 to 5, is not connected mutually between the annular LED wick sheet, has saved heat-conducting substrate 101 materials, reduces cost, and the contact area of LED wick sheet and air is increased, and radiating rate is accelerated, and is also more attractive in appearance.
The above is merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
