Abstract
The utility model discloses an SMD (surface mounted device) LED fluorescent lamp, which comprises a glass tube with two ends open, two end caps, a luminous device and two conductive electrodes, wherein the two end caps are respectively assembled together with the glass tube, the luminous device is arranged inside the glass tube, and the two conductive electrodes are assembled together with the end caps. The SMD LED fluorescent lamp is characterized in that the luminous device is axially arranged in the glass tube, the luminous device comprises a PCB (printed circuit board), a constant-current driver and a plurality of SMD LEDs, wherein the constant-current driver is mounted at one end of the PCB, one end of the PCB is assembled together with the end cap positioned at one end of the glass tube, the other end of the PCB is electrically connected with the conductive electrodes through the constant driver, and the SMD LEDs are arranged on the front side and the rear side of the PCB in a surface mounted manner. The size and weight of the SMD LED fluorescent lamp are only 1/10 to 1/15 of those of a traditional fluorescent lamp, and the SMD LED fluorescent lamp is less in power consumption, long in service life, uniform and soft in luminance, low in lamplight temperature and convenient in mounting.
Description
Technical field:
The utility model relates to the LED lighting technical field, is specifically related to a kind of SMD LED fluorescent lamp.
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 SMD 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 SMD 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, SMDLED 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 SMDLED fluorescent lamp 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 SMD LED fluorescent lamp; 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 SMDLED, 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 SMD LED are mounted on the tow sides of pcb board.
The tow sides of pcb board mount the SMD LED of delegation at least, and double-edged SMDLED is dislocation arrangement.
Beneficial effect: the utility model adopts SMD LED to make fluorescent lamp; Fluorescent lamp contrast with prior art; Its volume and weight has only 1/10～1/15 of traditional fluorescent lamp; Power consumption is few, long service life, luminous evenly soft, the light temperature is low, can be complementary with the fluorescent light bracket of prior art, and is easy for installation.
