Abstract
The utility model relates to a bulb adopting an LED light source, which comprises a lamp cup, a lamp head and an aluminium cardinal plate arranged on the lamp cup. A constant current source module is arranged in the lamp cup. The input end of the constant current source module is connected with the power supply interface of the lamp head, and the output end is connected with the aluminum cardinal plate. The front face of the aluminium cardinal plate is provided with an LED light source array. The utility model effectively reduces the quantity of heat of the LED light source and prolongs the service life of the LED light source through adopting the reasonable technical proposal that the constant current source module and a plurality of LED light sources form the LED light source array.
Description
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.
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, 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 low-power LED light sources.The mode of this many low-power 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.
The beneficial effects of the utility model are:
1. reasonable in design, stable performance;
2. by adopting closing of constant-current source assembly and many low-power LED light source LED light source consisting arrays
The reason technical scheme effectively reduces the led light source heat, prolongs the led light source life-span.
Description of drawings
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is overall structure figure of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is the overall structure figure of another embodiment of the utility model.
Among the figure: 1. Lamp cup, 2. lamp holder, 3. aluminium base, 4. low-power LED light source, 5. constant-current source assembly, 6. power interface, 7.PC protective cover.
The specific embodiment
Fig. 1 and Fig. 2 are embodiment of the present utility model.The utility model comprises Lamp cup 1, lamp holder 2 and is installed in aluminium base 3 on the Lamp cup 1, and wherein be provided with a constant-current source assembly 5 in the Lamp cup 1, the input of this constant-current source assembly 5 is connected with the power interface 6 of lamp holder 2, and its output is connected with aluminium base 3; Be equiped with the led light source array in the front of aluminium base 3.
In the present embodiment, described led light source array is made up of many low-power LED light sources 4.The mode of this many low-power LED light source 4 LED light source consisting arrays makes spread heat on every low-power LED light source 4, and heat is concentrated in use to have solved single high-power LED light source, is difficult for the drawback of heat radiation.In the present embodiment, a number of low-power LED light source 4 is no less than 12.
In use, when the utility model LED bulb and power connection, constant-current source assembly 5 can provide stable electric current for the led light source array on the aluminium base 3, thereby the brightness that guarantees the led light source array can not decay fast owing to the electric current instability, thereby has prolonged the service life of led light source.
Lamp cup 1 is provided with PC protective cover 7, and the PC protective cover 7 among the embodiment shown in Figure 3 is spherical, has both improved light efficiency, makes light more even simultaneously.
LED bulb of the present utility model, by adopting the rational technique scheme of constant-current source assembly and many low-power LED light source LED light source consisting arrays, effectively reduce the led light source heat, prolonged the led light source life-span, stable performance simultaneously, extensively adapt to various installation environments, have vast market prospect.
