Problems solved by technology

Because the light distribution function of the lampshade of the traditional LED lighting tube is one time, its light distribution effect is subject to many restrictions
Therefore, it is not suitable for use in some specific lighting environments. If you want the LED lighting to have some specific light distribution functions, you need to add other components, which will increase the production cost.

Embodiment 1

[0022] see figure 1 and figure 2 , Embodiment 1 of the present invention, an LED integral lighting tube lampshade with a lens light distribution function, including a lampshade body 100, the lampshade body 100 has a tunnel cavity 1, and a long strip is arranged in the middle of the top of the tunnel cavity 1 The lens 2 is provided with a light guide panel 3 on both sides of the strip lens 2, and a light-transmitting cover 4 is arranged above the strip lens 2, and the light-transmitting cover 4 is connected with the strip lens 2 to form a light-transmitting cavity 5 , the elongated lens 2 has an arc-shaped upper surface 6, and a concave groove 7 is arranged in the middle of the bottom of the elongated lens 2. The concave groove 7 is used to accommodate the LED light bar (not shown in the figure), and the light emitted by the LED light bar Refracted by the strip lens 2 and passed through the light-transmitting cavity 5 , it is scattered outward by the light-transmitting cover ...

Embodiment 2

[0032] see figure 1 , figure 2 , image 3 and Figure 4 , the second embodiment of the present invention, most of the structure is the same as the first embodiment, the difference is that: the light transmission cover 4 includes a first light transmission surface 41 and a second light transmission surface 42, wherein the first light transmission surface 41 The upper end is connected to the upper end of the second light-transmitting surface 42, the lower end of the first light-transmitting surface 41 is connected to one side of the strip lens 2, the lower end of the second light-transmitting surface 42 is connected to the other side of the strip lens 2, and the first light-transmitting surface 41 and the second light-transmitting surface 42 form an inverted "V"-shaped structure.

[0033] see Figure 5 , an LED overall lighting tube lampshade with a lens light distribution function according to an embodiment of the present invention is used on an LED lighting tube.

Abstract

The invention provides an LED-lighting-lamp-tube integral lampshade with a lens light distribution function. The lampshade comprises a lampshade body. The lampshade body is provided with a tunnel cavity. A long-strip lens is arranged in the middle of the top of the tunnel cavity. Light guide panels are arranged on the two sides of the long-strip lens correspondingly. A light-transmitting cover isarranged above the long-strip lens. The light-transmitting cover and the long-strip lens are connected to form a light-transmitting cavity. The long-strip lens is provided with an arc-shaped upper surface. A concave groove is formed in the middle of the bottom of the long-strip lens and used for containing an LED light-emitting lamp strip. Light emitted by the LED light-emitting lamp strip is refracted by the long-strip lens, passes through the light-transmitting cavity and then is scattered outwards by the light-transmitting cover. According to the technical scheme, the LED-lighting-lamp-tubeintegral lampshade is integrally formed, assembly is easy, multiple light distribution modes are achieved, the light-transmitting performance is good, the flexibility is high, the requirements of customers can be met, and the lampshade is more convenient for users to use.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED integral lighting tube lampshade with a lens light distribution function. Background technique [0002] LED lighting tubes are developed based on fluorescent tubes, so their specifications are divided into T5, T8, T10, T12, etc. according to diameter, among which T5 and T8 are widely used; according to length, they are divided into 0.3m, 0.6m, 0.9m, 1.2 m, 1.2m, 2.4m, etc., among which 0.6m and 1.2m are widely used. With the development of LED lighting, LED lighting tubes have also developed many specifications, and their structures have also undergone many changes. From the earliest profile lamp body to the plastic lamp body, and then to the glass tube lamp body; the power supply is from the external to the built-in back, and then to the built-in two ends. The development of LED lighting tubes has been varied. However, its development has not changed the method of usi...
