Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic diagram of an overall structure of an embodiment of the present invention.

In one embodiment of the present invention, the refraction device mainly comprises a first light-transmitting body 4 and a second light-transmitting body 5.

The first light-transmitting body 4 is opposite to the indicating lamp 2 and is mainly used for diffusing light emitted by the indicating lamp 2 so as to preliminarily improve the light source light-emitting area and the irradiation angle of the indicating lamp 2.

The second light-transmitting body 5 is connected to the first light-transmitting body 4 and is configured to re-radiate light emitted from the first light-transmitting body 4, so as to further improve the light source light-emitting area and the illumination angle of the indicator light 2.

So, the refraction device that this embodiment provided, through the first translucent body 4 and the second translucent body 5 of interconnect, successively two times diverge the light that pilot lamp 2 launched, compare the straight line in prior art and jet out the light-emitting mode, improved the light source light-emitting area of pilot lamp 2 by a wide margin, extended the angle of illumination of pilot lamp 2 by a wide margin, and then improved the luminous homogeneity of pilot lamp 2 at each angle.

As shown in fig. 2, 3 and 4, fig. 2 is a detailed structural schematic view of the first light-transmitting body 4 and the second light-transmitting body 5 shown in fig. 1, fig. 3 is a front view of fig. 2, and fig. 4 is a longitudinal sectional view of fig. 3.

In addition, in order to extend the optical path of the light emitted from the indicator lamp 2 in the second light-transmitting body 5 as much as possible, a reflector 6 is provided at the contact surface between the first light-transmitting body 4 and the second light-transmitting body 5. Specifically, one end of the reflector 6 is connected with the end face of the first light transmission body 4, the other end of the reflector 6 is connected with the end face of the second light transmission body 5, the reflector is mainly used for reflecting light, the direction of a light path is adjusted, and the light emitted from the end face of the first light transmission body 4 is reflected into the second light transmission body 5, so that the light scattered by the first light transmission body 4 can continuously move in the second light transmission body 5 until the light is emitted from the second light transmission body 5 to the end face of the end portion far away from the position where the light is connected with the first light transmission body 4. So set up, through the effect of reflector 6, will follow the heat dissipation light emission of the terminal surface department outgoing of first printing opacity body 4 to the second printing opacity body 5 in, follow the terminal surface outgoing of second printing opacity body 5 motion to utilize the second printing opacity body 5 to prolong the exit distance of light, and then increased the divergence distance of light, the light path is longer, can make light obtain more fully scattering, the printing opacity is more even, soft.

In general, the reflector 6 may be a flat mirror or the like. Obviously, the first light-transmitting body 4 and the second light-transmitting body 5 are both transparent materials, such as transparent PC, and the refractive indexes of the two are generally equal.

The first light-transmitting body 4 is vertically installed on the surface of the second light-transmitting body 5, and the reflector 6 is disposed obliquely with a reflection angle of 45 ° with respect to the incident light of the indicator lamp 2. With the arrangement, after the light of the indicator lamp 2 is emitted, the light can vertically enter the first light-transmitting body 4 and then horizontally exit the second light-transmitting body 5 after being reflected by the reflector 6, and the exit direction of the light path is adjusted by 90 degrees.

Of course, the specific installation angle of the first light-transmitting body 4 on the surface of the second light-transmitting body 5 is not fixed, for example, the first light-transmitting body 4 may be obliquely installed on the surface of the second light-transmitting body 5. Similarly, the connection angle of the reflector 6 between the first light-transmitting body 4 and the second light-transmitting body 5 is not limited to 45 °, and the other angles, such as 30 ° to 60 °, may be adopted, and the specific requirement is determined according to the actual light emitting direction.

With this arrangement, the concave surface 41 of the first light transmission body 4 forms a concave lens effect for the light emitted from the indicator lamp 2, and similarly, the convex surface 51 of the second light transmission body 5 also forms a concave lens effect for the reflected emergent light of the first light transmission body 4. To ensure uniform scattering of the concave lens and the convex lens, the concave surface 41 and the convex surface 51 have the same curvature, but the concave directions are opposite.

In addition, for the scattering distance of extension pilot lamp 2 as far as possible, improve the scattering effect, in this embodiment, first printing opacity body 4 specifically is the notch cuttype, includes the overlapping structure of two rectangles to concave surface 41 sets up the ladder top surface at first printing opacity body 4, and is convenient just right with pilot lamp 2.

Similarly, the first light-transmitting body 4 can be specifically disposed at the edge region of the second light-transmitting body 5, so as to ensure the maximum scattering distance of light in the second light-transmitting body 5.
