The light reflection device (3) is arranged on a reflector plate on the inner wall of the tube casing (1) via a support or a clamping groove, and the light emitted by an LED chip (4) is uniformly dispersed and flooded out of the tube casing (1). The novel LED tube provided reduces the cost of tubing and the cost of an LED tube, and improves the luminescence utilization rate of LEDs.

Description

A kind of Novel LED lamp tube

Technical field

The utility model relates to the LED light fixture, more particularly, relates to a kind of Novel LED lamp tube.

Background technology

Prior art LED fluorescent tube, direct projection LED light is inhomogeneous not soft, for reaching the luminous scattering floodlight of LED effect, usually adopts the emulsification plastics as fluorescent tube, and its deficiency is that the fluorescent tube cost is high, and simultaneously, the light consumption is large.

The utility model content

Problem to be solved in the utility model is to provide a kind of LED fluorescent tube, guarantees improve the utilization rate of light and reduce the fluorescent tube cost on the soft even basis of light.

The utility model the problems referred to above solve like this, construct a kind of Novel LED lamp tube, comprise shell, be contained in the LED luminous plaque at the end in described shell, and to described LED luminous plaque the luminous light reflecting device that reflects.

In above-mentioned Novel LED lamp tube, described shell is the hollow tube that light transmissive material is made, and its end face has pin.

In above-mentioned Novel LED lamp tube, described LED luminous plaque is a circuit board of axially installing along shell, and a plurality of LED chips are housed on one face, and is relative with described light reflecting device.

In above-mentioned Novel LED lamp tube, described LED luminous plaque is two circuit boards of axially installing along shell, respectively have on a face LED chip is housed, described circuit board has respectively an avris to be contained in inner wall of tube shell, another avris every sky toward each other, the part reflection that described light reflecting device is luminous by described LED chip, the space that the light of reflection passes between described circuit board exhales described shell again.

In above-mentioned Novel LED lamp tube, described smooth reflector element is to be arranged on the reflector on inner wall of tube shell by support or draw-in groove, the luminous quilt of LED chip is evenly dispersed with flood and gone out described shell.

In above-mentioned Novel LED lamp tube, described reflector has a reflective surface.

In above-mentioned Novel LED lamp tube, the reflective surface of described reflector is provided with many make that reverberation disperses concavo-convex.

In above-mentioned Novel LED lamp tube, described light reflecting device be coated in described shell with described LED light-emitting area phase inwall on the reflectorized material coating.

Implement Novel LED lamp tube of the present utility model, its beneficial effect is, owing to having adopted light-transmitting materials, reduced the tubing cost, also improved the luminous utilization rate of LED, because reverberation replaces direct light, improved luminous soften.

The specific embodiment

Referring to figs. 1 through Fig. 4, Fig. 1 is the structural representation of Novel LED lamp tube the first embodiment, and according to this embodiment, this Novel LED lamp tube comprises circular shell 1, at shell 1, LED luminous plaque 2 and light reflecting device 3 is housed.Shell 1 is circular hollow tube, and its end face is provided with pin one 1, and its size conforms has the fluorescent tube standard now, and shell 1 can adopt light transmissive material for example to make glass or transparent plastic is made, and ensures very low cost and good light transmission.The shape of shell 1 can be circular, can be also ellipse or triangle or rectangle etc.

Shell 1 two ends are formed with the first space 12, can be used for installing electronic accessory parts, the another accessory of electronics also can partly or entirely be arranged on LED luminous plaque 2, in shell 1, removing the first zone in addition, space 12 is second space 13, between the first space 12 and second space 13, be provided with dividing plate 14, LED luminous plaque 2 and light reflecting device 3 are housed in second space 12.LED luminous plaque 2 is one and axially installs and with electronic components or pin one 3, the strip circuit board that is electrically connected to arranged along shell 1, the two ends of LED luminous plaque 2 are embedded in respectively in dividing plate 14, LED luminous plaque 2 both sides are transparent zone territory 8, LED luminous plaque 2 face up is light-emitting area 21, be on light-emitting area 21, to be furnished with a plurality of LED chips 4, its LED chip 4 is connected with circuit board.above LED luminous plaque 2, be provided with light reflecting device 3, in the present embodiment, light reflecting device 3 is a rectangular arc platy structure, light reflecting device 3 can be arranged on the inwall of shell 1 by support 6 or draw-in groove, the concave surface of light reflecting device 3 is reflective surface 31, this reflective surface 31 is relative with the light-emitting area 21 that LED forms, on reflective surface 31, be provided with concaveconvex structure 32, for example, evenly or the sags and crests of non-uniform Distribution, equally distributed tongue and groove, the light generation diffuse reflection that the light-emitting area 21 that can make this concaveconvex structure 32 transmits, irreflexive light spreads out of shell 1 by transparent zone territory 8.Reflective surface 31 can adopt reflectorized material to make.
