Description

The LED lamp that drive circuit is built-in
Technical field
The utility model relates to the LED lamp, the LED lamp that particularly a kind of drive circuit is built-in.
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 existing LED lamp includes drive circuit and radiator, and volume is excessive.
Summary of the invention
The utility model technical problem to be solved is: propose the built-in LED lamp of a kind of drive circuit, drive circuit is placed in the radiator, reduced volume, structure is simpler, also reduces cost.
The utility model proposes the built-in LED lamp of a kind of drive circuit; Comprise the lampshade, the aluminium base that cover on light-emitting window, be arranged on LED lamp pearl, drive circuit and radiator on the aluminium base; Said radiator comprises the base plate that a lower surface is connected with said aluminium base and evenly is arranged on some heat sink strips at the edge of said base plate upper surface; Said heat sink strip forms a cavity round said base plate; Said drive circuit places in the said cavity, is connected through a heat insulation structural between said radiator and the said drive circuit to be fixed up.
Preferably, said heat insulation structural is the shell that a plastic material is processed, and said drive circuit places in the said shell.
Preferably, evenly be provided with some air vents on the said base plate, said air vent is round said substrate setting.
Preferably, said lampshade is connected with said radiator, said lampshade comprise an aluminium cover be arranged on the said aluminium cover with the adaptive transmissive mirror of said LED lamp pearl, said transmissive mirror is corresponding one by one with said lamp pearl.
The utility model places drive circuit in the radiator, has reduced volume, and structure is simpler, also reduces cost.
Description of drawings
Fig. 1 is the structural representation before the installing drive circuit among the embodiment of the built-in LED lamp of the utility model drive circuit;
Fig. 2 is the structural representation behind the installing drive circuit among the embodiment of the built-in LED lamp of the utility model drive circuit.
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 built-in LED lamp of the drive circuit 40 of the utility model is proposed, comprise the lampshade, the aluminium base 30 that cover on light-emitting window, be arranged on LED lamp pearl 301, drive circuit 40 and radiator on the aluminium base 30.Said radiator comprises the circular bottom plate 20 that a lower surface is connected with aluminium base 30 and evenly is arranged on some heat sink strips 203 at the edge of circular bottom plate 20 upper surfaces.The center of base plate 20 lower surfaces is provided with a circular groove 201 adaptive with aluminium base 30, and aluminium base 30 places in the groove 201 and is connected with base plate 20.Heat sink strip 203 is vertical with base plate 20 upper surfaces, and heat sink strip 203 forms a circular cavity round base plate 20, and said drive circuit 40 places in the said cavity, is connected through a heat insulation structural between said radiator and the said drive circuit 40 to be fixed up.Said heat insulation structural is the shell 401 that a plastic material is processed, and said drive circuit 40 places in the said shell 401, is wrapped in by shell 401 and places cavity, has reduced volume like this, and structure is simpler.
Evenly be provided with some air vents that are used to dispel the heat 202 on the said base plate 20, air vent 202 forms a circle round substrate 30.The LED lamp pearl 301 luminous great amount of heat that can produce; Heat can distribute from air vent 202; And by aluminium base 30 rapidly with the heat transferred radiator, by the heat sink strip on the radiator 203 heat is distributed, radiating effect is obvious; Can prevent that LED lamp pearl 301 is overheated, prolong the service life of LED lamp.
Said lampshade is connected with said radiator, and said lampshade comprises an aluminium cover 10 and the transmissive mirror 101 adaptive with said LED lamp pearl 301 that is arranged on the said aluminium cover 10, and said transmissive mirror 101 is corresponding one by one with said lamp pearl 301.The light that LED lamp pearl 301 sends forms soft light after transmissive mirror 101; Thereby the light that shines out does not have dazzle property; Can be not dazzling, can effectively improve the drawback of LED lamp pearl luminous solar flare of 301 luminous generations and strong dazzling light, improved the brightness of illumination of LED lamp pearl 301 simultaneously.
The above is merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion 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.
