[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] As Figure 1 and Figure 2As shown, a lamp strip for uniformly refracting light rays comprises a housing 10, one side of the housing 10 is provided with a strip-shaped lampshade 20, the side of the lampshade 20 facing the inside of the housing 10 comprises convex portions 21 and concave portions 22, the convex portions 21 and the concave portions 22 are alternately arranged along the eye direction of the lampshade 20, one light source 30 is arranged below each convex portion 21 in the housing 10, and the light transmittance of the lampshade 20 is 60%-80%. The lamp strip of the present application realizes the refraction of the light source 30 in the lampshade 20 through the structure of the convex portions 21 and the concave portions 22 of the lampshade 20, the arrangement of the light source 30 below the convex portions 21, and the light transmittance of the lampshade 20, and finally makes the distributed light source 30 show a uniform light effect on the lamp strip. Thus, the problem of uneven light effect of the long strip-shaped lamp strip is solved.

[0022] Both sides of the housing 10 are respectively provided with mounting ears 11, and mounting holes 12 are formed in the mounting ears 11. The lamp strip is fixed on an object through the mounting ears 11, and the mounting holes 12 are used for the fixing objects such as screws to pass through to fix the lamp strip.

[0023] The light transmittance of the lampshade 20 is 70%. Through experiments, it is found that the uniformity of light rays is better when the light transmittance of the lampshade 20 is 70%.

[0024] As shown in the figure, Figure 3 The housing 10 is provided with a surrounding wall 13, the surrounding wall 13 surrounds the convex portions 21 and the concave portions 22 of the lampshade 20, and is used for converging the light rays of the light source 30. The surrounding wall 13 converges the light rays of the light source 30 to the convex portions 21 and the concave portions 22, so as to avoid as much as possible the refraction of the light source 30 inside the housing 10, and after the surrounding wall 13 surrounds the convex portions 21 and the concave portions 22, the light rays of the light source 30 are more convergent, so that the light illumination displayed by the lampshade 20 is brighter. The surrounding wall 13 can be a mouth-shaped type, which surrounds the convex portions 21 and the concave portions 22, or can be a C-shaped type, which surrounds the convex portions 21 and the concave portions 22 together with an inner wall of the housing 10.

[0025] The side of the lampshade 20 away from the housing 10 is a plane. The outer surface of the lampshade 20 is a plane, and the light source 30 below is uniformly emitted from the plane after refraction through the convex portions 21 and the concave portions 22. The plane is a certain height away from the housing 10, and the height is between 1-2 cm.

[0026] The distance between the light source 30 and the convex portion 21 is between 1 cm and 2 cm. The cross section of the convex portion 21 and the concave portion 22 is a wave shape, and the wave shape is a sine function. The greater the amplitude of the sine function, the greater the corresponding period, and the smaller the amplitude, the smaller the corresponding period.

[0027] As shown in the figure, Figure 4 The side of the housing 10 away from the lampshade 20 is provided with a wire hole 14. The wire hole 14 is used for the wires of the light source 30 to pass through.

[0028] AsFigures 5-8 As shown, the light path of the ordinary lamp strip with a flat bottom is simulated, and the light display effect of the lampshade 20 under 80% transmittance, 70% transmittance and 60% transmittance is analyzed. Figures 9-12 As shown, the light path of the lamp strip of the present application is simulated, and the light display effect of the lampshade 20 under 80% transmittance, 70% transmittance and 60% transmittance is analyzed, it can be seen that the light of the present application is more uniform, the transmittance should be between 60%-80%, and the transmittance of 70% is preferred.

[0029] The above is only the preferred embodiment of the present application, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical solution belonging to the idea of the present application belongs to the protection scope of the present application. It should be pointed out that for ordinary skilled in the art, some improvements and decorations without departing from the principle of the present application, these improvements and decorations should also be considered as the protection scope of the present application.
