As the built-in power supply adopts the constant current diode, the built-in soft light LED fluorescent lamp has the advantages of simple circuit, small occupied space and high power supply efficiency; and the light mixing effect can avoid the emergence of light spots of the LED fluorescent lamp, achieve soft and uniform light, and have no glare, so that the performance is more reliable.

Description

Built-in sheen LED fluorescent lamp

Technical field

The utility model relates to the electric light source technology field, particularly a kind of built-in sheen LED fluorescent lamp.

Background technology

Over past ten years, the LED light emitting diode has obtained increasingly extensive application as a kind of green, energy-conservation emerging light source.General LED light fixture has power consumption little, and luminous efficiency height, emission response time are extremely short, and be radiationless, many advantages such as long service life.But existing some problems of LED fluorescent lamp ubiquity, external causing of power supply installed complexity, and light-emitting area has luminous point in addition, dazzles optical issue etc.In general LED fluorescent lamp, 3528 the LED that adopt more, its light-emitting area is little, lighting angle is 120 degree, in the practical application, normal adopt many row's structures, make the easier luminous point that occurs of LED fluorescent lamp, thereby make the light-emitting area of fluorescent lamp even inadequately, many simultaneously row's structures also can reduce the reliability of fluorescent lamp.

The utility model content

The technical problems to be solved in the utility model is: a kind of built-in sheen LED fluorescent lamp is provided, has solved that existing daylight lamp power source is external to cause installing complicated, and light-emitting area has luminous point, dazzles problem such as light.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of built-in sheen LED fluorescent lamp, comprise shell, lamp holder, some LED and aluminium base, shell two ends socket lamp holder, the aluminium base setting in the enclosure, shell is made up of diffusion shell and aluminum pipe, the atomizing diffusion shell of described diffusion shell for being mixed and made into by diffusant and Merlon, and the transmitance of diffusion shell is 85%, LED is three wafer one packaged type LED, and LED becomes single array distribution and is fixed on the aluminium base; Shell is built-in with power supply, is provided with the current regulator diode of doing constant current control in the circuit of power supply, and the circuit connecting relation of LED is some string LED parallel connection, and every string LED is formed by the wafer tandem of equal number.、

LED is 16.8mm to the distance of diffusion shell, helps abundant mixed light.

Distance on the aluminium base between adjacent LED is 9.4mm, can reach good mixed light effect.

The beneficial effects of the utility model are: adopt built-in power, and the power-efficient height, electromagnetism is noiseless, and it is little to take up room; Adopt the single arrangement of LED of 5050 encapsulating structures, and the atomizing diffusion shell of high permeability, can reach good mixed light effect, make the LED fluorescent lamp luminous point no longer occur, light is soft evenly, does not have and dazzles light, and performance is more reliable.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

Shown in Fig. 1,4, a kind of built-in sheen LED fluorescent lamp, comprise shell 1, lamp holder 2, some LED3 and aluminium base 4, shell 1 two ends socket lamp holder 2, aluminium base 4 is arranged in the shell 1, and shell 1 is made up of diffusion shell 11 and aluminum pipe 12, the atomizing diffusion shell of described diffusion shell 11 for being mixed and made into by diffusant and Merlon, the transmitance of diffusion shell 11 is 85%, and LED3 is three wafer one packaged type LED, and LED3 becomes single array distribution and is fixed on the aluminium base 4; Shell 1 is built-in with power supply, is provided with the current regulator diode of doing constant current control in the circuit of power supply, and the circuit connecting relation of LED3 is some string LED3 parallel connection, and every string LED3 is formed by the equal number wafer tandem.

The utility model adopts built-in power, and in order to solve the limitation of design space, circuit mainly adopts current regulator diode to do constant current control, at working voltage is the area of 100VAC, the led circuit annexation be 36 strings 10 also, promptly every string LED3 is formed by 36 wafer tandem, and then by 10 connection in series-parallel; At working voltage is the area of 220V or 230V, the led circuit annexation be 90 strings 4 also, promptly every string LED3 is formed by 90 wafer tandem, and then by 4 connection in series-parallel, this simple in circuits, the reliability height, the power-efficient height, engaged position is little.

As shown in Figure 2, three wafer one packaged type LED3 are that three wafers are encapsulated on the LED, be the LED of model 5050 encapsulating structures, its light-emitting area is bigger as can be seen from Figure, lens above the LED3 can make its lighting angle increase to 120 degree simultaneously, distribution curve flux as shown in Figure 3, these all are beneficial to the mutual mixed light of a plurality of LED3.

From Fig. 1,4, can find out, the overall structure of the utility model LED fluorescent lamp, LED3 adopts single array distribution, and LED3 is bigger to the light mixing distance of diffusion shell 11, can reach 16.8mm.Distance between the adjacent LED 3 must cooperate the structure of whole light fixture and the fogging degree of diffusion shell to determine, the utility model employing transmitance is 85% atomizing diffusion shell, and adjacent LED 3 spacings are 9.4mm, can reach good mixed light effect.
