The utility model discloses a LED bulb, including a PC protective cover, a lamp holder, an aluminum heat radiator and an aluminum substrate arranged on the heat radiator, the heat radiator is providedwith a constant-current source assembly which input end is connected with a power supply interface of the lamp holder and which output end is connected with the aluminum substrate; the front face ofthe aluminum substrate is provided with a LED light source array. By means of employing the constant-current source assembly and the LED light source array composed of a plurality of 0.1W SMD LED light sources and emitting the heat generated by the LED light source array through the heat radiator, the utility model is capable of effectively reducing LED light source heat quantity and prolongs LEDlight source longevity, and the brightness of the LED bulb is higher than that of the high-power led bulb of equal power.

Description

The LED bulb
Technical field
The utility model relates to a kind of lighting, particularly a kind of bulb that adopts led light source.
Background technology
At present, the indoor or outdoors lighting that is widely used mostly is incandescent light bulb or fluorescent tube, but the electro-optical efficiency of these two kinds of products is all lower, and caloric value is big, and service life is shorter.
The LED lighting engineering is through years of development and accumulation, shown outstanding energy-saving effect, led light source has advantages such as volume is little, energy consumption is low, caloric value is low, the life-span is long as a kind of emerging semiconductor light-emitting elements, some have therefore also occurred and has adopted the light fixture of led light source.But these light fixtures are for pursuing brightness, most high-power LED light sources that adopt.Though LED is a cold light source, when work, still can produce heat, serious decay appears in the brightness meeting at high temperature of LED lamp.These adopt the lamp light source of high-power LED light source to be in sealing state, and heat is not easy to scatter, and often promptly reaches higher temperature in the short time, causes brightness to decay fast, has a strong impact on light source life.Therefore high-power LED light source is used for the indoor or outdoors lighting and does not obtain good result, the light decay problem that causes in order to reduce heat of some producer simultaneously, and the employing low-power LED, because the brightness of low-power LED is very low, usually need a large amount of LED to carry out assembled arrangement, always caused volume excessive, the problem that power rises.
In addition, because led light source has higher requirement for the stability of power supply,, also be a major reason that influences light source life if the electric power outputting current instability also very easily causes the quick decay of LED brightness.
Summary of the invention
The purpose of this utility model is to solve existing existing the problems referred to above of lighting, and a kind of rational in infrastructure, caloric value is low, the life-span is long LED bulb is provided.
The technical scheme that the utility model adopted is: a kind of LED bulb, comprise Lamp cup, PC protective cover, lamp holder and be installed in aluminium base on the Lamp cup, be provided with a constant-current source assembly in the Lamp cup, the input of this constant-current source assembly is connected with the power interface of lamp holder, its output is connected with aluminium base; The aluminium base front is equiped with the led light source array.
The utility model is provided with the constant-current source assembly in Lamp cup, this constant-current source assembly connects the power interface of aluminium base and lamp holder, like this, when the utility model LED bulb and power connection, the constant-current source assembly can provide stable electric current for the led light source array on the aluminium base, thereby the brightness that guarantees the led light source array can the decay fast owing to the electric current instability.
In addition, the led light source array of the utility model employing is made up of many 0.1w SMD led light sources.The mode of this many 0.1w SMD led light source LED light source consisting arrays, heat is concentrated in use to have solved single high-power LED light source, is difficult for the drawback of heat radiation, has also solved small-power brightness and has reached the drawback that causes volume to increase the power increase inadequately.In the brightness considerably beyond the bulb of forming with the constant power great power LED.
On the other hand, the aluminium radiator on the LED bulb is set up, better the heat that produces for LED distributes fast.Guaranteed the life-span of LED.
The beneficial effects of the utility model are:
1. reasonable in design, stable performance;
2. by adopting the rational technique scheme of constant-current source assembly and many 0.1w SMD led light source LED light source consisting arrays, effectively reduce the led light source heat, improved the brightness of bulb, prolong the led light source life-span.
3. adopt the mode of aluminium radiator and aluminium base, make its heat fast and carry out exchange heat in the air, heat is distributed, guaranteed that the light decay of LED reduces to minimum.
Description of drawings
Figure is a structural representation of the present utility model;
The specific embodiment
The utility model comprises radiator 3, lamp holder 2 and is installed in aluminium base 5 on the radiator 1, and wherein be provided with a constant-current source assembly 4 in the radiator 3, the input of this constant-current source assembly 4 is connected with the power interface 1 of lamp holder 2, and its output is connected with aluminium base 5; Be equiped with SMD led light source 6 arrays in the front of aluminium base 5.
In the present embodiment, described led light source array is made up of 0.1w SMD led light source 6.The mode of this 0.1WSMD led light source 6 LED light source consisting arrays, make spread heat on every 0.1w SMD led light source 6, be transmitted on the radiator 3 by aluminium base 6, radiator 3 carries out exchange heat with air and rapidly the heat that LED 6 produces is distributed again.Heat is concentrated in use to have solved single high-power LED light source, is difficult for the drawback of heat radiation.It is not enough also to have solved low-power LED brightness, the drawback that light decay is big.In the present embodiment, a number of 0.1w SMD led light source 4 is no less than 30.
In use, when the utility model LED bulb and power connection, constant-current source assembly 4 can provide stable electric current for 6 arrays of the led light source on the aluminium base 5, thereby the brightness that guarantees 0.1w SMD led light source array can not decay fast owing to the electric current instability, thereby has prolonged the service life of led light source.
Radiator 3 is provided with PC protective cover 7, and the PC protective cover 7 among the embodiment shown in the figure is spherical, has both improved light efficiency, makes light more even simultaneously.
LED bulb of the present utility model, by adopting the constant-current source assembly, the rational technique scheme of aluminium radiator and 0.1w SMD led light source LED light source consisting array, effectively reduce the led light source heat, prolonged the led light source life-span, improved the brightness of bulb, stable performance simultaneously, extensively adapt to various installation environments, have vast market prospect.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
