Abstract

The utility model discloses a surface-mounted LED lamp tube. The surface-mounted LED lamp comprises a glass lamp tube with two opening ends, two end covers respectively assembled with the glass lamp tube, a light emitting device arranged in the glass lamp tube, and two conductive electrodes assembled with each end cover. The surface-mounted LED lamp tube is characterized in that the light emitting device is arranged along the axial direction in the glass lamp tube, and includes a PCB (printed circuit board), a constant-current driver, and a plurality of surface-mounted LEDs; the constant-current driver is mounted on one end of the PCB; one end of the PCB is assembled together with the end cover on one end of the glass lamp tube, and the other end of the PCB is electrically connected with the conductive electrodes through the constant-current driver; and the plurality of surface-mounted LEDs are mounted on the front and rear sides of the PCB. The surface-mounted LED lamp tube provided by the utility model is reduced in size and weight, which are 1/10 to 1/15 those of the conventional fluorescent lamp, so that the lamp tube is convenient in installation and has the advantages of less power consumption, long service life, uniform and gentle light, and low light temperature.

Description

A kind of paster LED fluorescent tube

Technical field:

The utility model relates to the LED lighting technical field, is specifically related to a kind of paster LED fluorescent tube.

Background technology:

Fluorescent lamp commonly used generally adopts filament heating, excited gas Discharge illuminating, and this fluorescent lamp power consumption is big, service life short, the fluorescent tube volume is big, has been not suitable for continuing to use.Along with the development of LED technology, the LED fluorescent lamp also occurs in succession, has much the trend that replaces traditional fluorescent lamp.Though the direct insertion fluorescent lamp power consumption of prior art is little, brightness is high, because shortcomings such as its heat dispersion is poor, optical attenuation is big, product weak point in service life are not suitable for the modern life yet.SMD LED is a kind of LED that grew up in recent years, and paster LED is exactly the meaning of surface patch light emitting diode, is a kind of solid-state semiconductor devices, and it can directly be converted into light to electricity.Wherein paster LED more is used for display screen and field of light fittings, has advantages such as volume is little, angle of scattering is big, uniformity of luminance is good, reliability is high, speed of production is fast, purposes is wide, and its glow color can be that white light is at interior shades of colour.Therefore, paster LED is applied in also becomes inexorable trend in the fluorescent lamp.

The utility model content:

The purpose of the utility model is exactly the deficiency to prior art, and a kind of paster LED fluorescent tube is provided, and has simple in structure, advantages such as lamp hole temperature is low, power consumption is little, long service life.

In order to achieve the above object, the technological solution of the utility model is following:

A kind of paster LED fluorescent tube; Comprise the glass lamp of both ends open, two end caps that are assembled together with glass lamp respectively, place the inner light-emitting device of glass lamp and two conductive electrodes that are assembled together with each end cap; It is characterized in that: light-emitting device is axial setting in glass lamp; Light-emitting device comprises pcb board, constant-flow driver and several paster LEDs, and constant-flow driver is installed in an end of pcb board, and an end of pcb board is assembled together with the end cap that is positioned at glass lamp one end; The other end of pcb board is electrically connected through constant-flow driver and conductive electrode, and several paster LEDs are mounted on the tow sides of pcb board.

The tow sides of pcb board mount delegation's paster LED at least, and double-edged paster LED is dislocation arrangement.

Beneficial effect: the utility model adopts paster LED to make fluorescent tube; Fluorescent tube contrast with prior art; Its volume and weight has only 1/10～1/15 of traditional fluorescent lamp fluorescent tube; Power consumption is few, long service life, luminous evenly soft, the light temperature is low, can be complementary with the lamp tube socket of prior art, and is easy for installation.
