360-degree light-emitting t8 fluorescent tube for LED (light-emitting diode) direct plug-in type LED

Abstract

The invention discloses a 360-degree light-emitting T8 fluorescent tube for an LED (Light-emitting Diode) direct plug-in type LED, which comprises two aluminum lamp holders, an acrylic tube, a diffusion film upper part, a diffusion film lower part, a front surface of a circuit board, a back surface of the circuit board and LED lamp beads. The 360-degree light-emitting T8 fluorescent tube is characterized in that the diffusion film lower part is placed and adhered onto the inner wall of the acrylic tube according to the clamping position in the tube; the lamp beads of the LED small-power direct plug-in type LED are placed on the circuit board according to a hole site; the front surface of the circuit board is a lamp bead spherical surface light-emitting part; the back surface of the circuit board adopts the structure that a lamp bead positive supporting frame and a lamp bead negative supporting frame are welded on a circuit of the circuit board; after each lamp bead is installed, the circuit board is installed into the acrylic tube; the two aluminum lamp holders are welded at the two ends of the acrylic tube and are connected with the circuit of the circuit board through power lines; small circular holes for allowing the LED direct plug-in type LED lamp beads to be placed in are arranged on the circuit board; and with the adoption of the whole light emitting principle of the small-power direct plug-in type LED, the rear surface also can emit light rays through the small circular holes to achieve the effect of emitting the light from 360 degrees. The 360-degree light-emitting T8 fluorescent tube is simpler in structure, breaks through the technology that the LED small-power direct plug-in type LED is utilized to manufacture the fluorescent tube and can emit the light from 360 degrees.

Description

technical field

[0001] The utility model relates to a solar tube, in particular to an LED in-line light-emitting diode 360-degree light-emitting T8 solar tube. Background technique

[0002] Conventional fluorescent tubes are mainly composed of glass tubes, ballasts and starters. There is a filament at each end of the lamp tube. The tube is filled with thin argon and trace mercury vapor, and the tube wall is coated with fluorescent powder. The disadvantages are: both ends of the fluorescent tube are easy to black, the lamp tube is fragile and explosive, the filament ages and volatilizes quickly, the life of the luminous efficiency is too short, the service life is 3000-5000 hours, the glass tube contains mercury, and the lamp tube is made of easy Broken glass is used as the shell. Once the glass is broken, the mercury in it will evaporate into the air immediately, and the mercury concentration in the surrounding air can reach 10-20 mg / m3 in an instant, which is 1000-2000 time...
