Embodiment 1

[0013] Such as figure 1 As shown, the lamp tube of this embodiment includes LED 1 , LED lamp board 2 , striped transparent cover 3 and tube base 4 . The LED lamp board 2 is equipped with LEDs, and the LED lamp board 2 and the striped light-transmitting cover 3 are fixed on the tube base 4 respectively. As a result, the point light emitted by a single LED 1 is converted into linear light.

Embodiment 2

[0015] Such as figure 2 As shown, the lamp tube of this embodiment, in addition to including all the components of Embodiment 1, is also covered with a light-transmitting outer cover 5 outside the striped light-transmitting cover 3, and the light-transmitting outer cover 5 is fixed on the tube base. The stripe direction of the light-transmitting outer cover is parallel to the axial direction of the lamp tube. The lamp tube of this embodiment can convert point light emitted by a single LED 1 into planar light.

[0016] In the above two embodiments, on the inner and outer surfaces of the striped light-transmitting cover and the light-transmitting outer cover, the directions of the strip-shaped grooves are parallel to each other. In other embodiments, it can also be designed as a structure in which the slotting directions on their inner and outer surfaces are perpendicular to each other. lamp.

Abstract

The invention relates to an LED light tube which belongs to the technical field of lighting decoration. The LED light tube comprises an LED, a tube support, a light panel and a transparent cover. At least one surface of the inner surface and outer surface of the transparent cover is provided with a strip groove which has notching direction vertical to the direction of a light tube axle. The invention solves the problems of globular-shaped facula and glare of LED, and has the advantages of simple manufacturing technique and low cost.

Description

technical field [0001] The invention belongs to the field of semiconductor lighting, and in particular relates to a lamp tube using LED as a light source. Background technique [0002] LED is a high-efficiency and energy-saving light source with the advantage of long working life, so LED lighting products have become the direction of research and application in the lighting industry. The existing cylindrical or tubular LED lamps have the following typical optical processing technologies: one is to add a transparent cover on the strip LED lamp board, and the lamp tube presents a dot-like spot; the other is A strip light-transmitting cover parallel to the axial direction of the lamp tube is installed on the strip-shaped LED lamp board, and the lamp tube presents a plurality of linear lights perpendicular to the axial direction of the lamp tube. The disadvantage of these two kinds of lamps is that there is a radiation blind area, the brightness on the lamps is uneven, the glar...
