[0034] In order to reduce the reflection loss of light on the first light exit face 2c, the surface of the first light exit face 2c is treated with skin lines to increase the diffuse reflection effect of light, thereby improving the illumination efficiency and enhancing the uniformity of light, and at the same time, the yellow light spot caused by the light source can be eliminated.

[0035] In the application, the included angle between the mounting surface 2a and the axis of the taper body 22 is greater than or equal to 60 degrees and less than or equal to 70 degrees, which has a large inclination angle and meets the design requirements of large-angle deflection of light and inclined installation of the light source.

[0036] In order to further improve the light exit direction and distribution, a second lens 5 is arranged at the light exit end of the cup lens 2. In the present application, the second lens 5 is arranged at the light exit end of the cup lens 2, and a second light entrance surface 5a and a second light exit surface 5b are arranged on the second lens 5. The second light entrance surface 5a is the light entrance end, which is attached to or parallel to the first light exit surface 2c. The second light exit surface 5b is the light exit end, which is inclined to the second light entrance surface 5a, thereby changing the light exit direction. The included angle between the second light exit surface 5b and the second light entrance surface 5a is greater than or equal to 7 degrees and less than or equal to 10 degrees. In the present application, the second lens 5 is a cuboid, also known as a crystal block lens. The length direction of the second lens 5 is in the same plane as the axis of the cup lens 2. In the present embodiment, the axis of the cup lens 2 is on the median plane of the length direction of the second lens 5. At the same time, the plane on which the second light exit surface 5b is located is parallel to the length direction of the second lens 5.

[0037] Specifically, the second lens 5 (crystal block lens) includes a first lens block 51 and a second lens block 52 arranged at the lower end of the first lens block 51. The first lens block is a cuboid, and its top surface is a plane, forming the second light entrance surface 5a. The bottom surface of the second lens block is a plane, forming the second light exit surface 5b, which is inclined to the second light entrance surface 5a. An included angle is formed between the second light exit surface and the width direction of the second lens 5, and the included angle is 7-10 degrees. The profile size of the second lens block 52 is larger than that of the first lens block 51, and its side wall is in the shape of a gemstone. Specifically, the side wall of the second lens block 52 includes a first inclined surface 521, a second inclined surface 522 and a third inclined surface 523 arranged in sequence from top to bottom. The first inclined surface 521 is connected to the side wall of the first lens block 51, and the first inclined surface is an upwardly inclined surface, i.e. towards the light entrance direction. The third inclined surface 523 is connected to the second light exit surface, and it is a downwardly arranged inclined surface, i.e. towards the light exit direction.

[0038] After adopting the above structure, the cup lens 2 and the second lens 5 are combined and the optical path is simulated. Referring to Figure 12 As can be seen from the figure, the cup lens 2 mainly collects the large-angle light emitted by the light-emitting diode and changes it into small-angle light. The collected exit light is close to the irradiation center, maintaining a certain degree of concentration. In this way, the light on the first light exit surface converges into a roughly circular light spot. At the same time, through the refraction of the second lens 5, the refraction angle is increased, meeting the lighting needs of the driver and the co-driver.

[0039] In the application, the mounting shell includes a first shell 3 for mounting the cup lens 2 and a second shell 4 mounted on the lower end of the first shell by buckling and used for mounting the second lens 5, and an arc surface 41 is arranged on the outer edge of the light outlet end of the second shell 4 to improve the overall aesthetic appearance; buckles are arranged on the side walls of the cup lens 2 and the second lens, and the buckles are fixed in the buckle holes of the first shell or the second shell through the buckles to realize quick connection and assembly; because the angle of light emitted by the light source is too large, part of the light will overflow the lens surface, so the periphery of the cup lens 2 and the second lens 5 is shaded by the above-mentioned shell to block the unnecessary stray light and avoid the light leakage phenomenon.

[0040] After assembly, it includes a horizontally arranged circuit board 1 (base plate), two light sources 11 are arranged on the base plate, the light source 11 is a light emitting diode, the cup lens 2 is mounted on the lower end of the base plate, specifically, the mounting surface 2a of the upper end of the cup lens 2 is also parallel to the circuit board 1 and can be attached to the circuit board, and the light source 11 is located in the recess 20 on the mounting surface 2a, the cup lens is two and is arranged on the two light sources 11 respectively, the two light sources are arranged left and right with the front of the vehicle as the front, and the two cup lenses are also arranged outward, the second lens is arranged on the lower end of the cup lens, the second light inlet surface of the second lens is parallel or attached to the first light outlet surface of the cup lens, at the same time, the length direction of the second lens is parallel to the left-right direction of the vehicle, and the second light outlet surface thereof is inclined forward, and can refract the emitted light to the instrument panel direction.

[0041] The cup lens emits the light path downward and outward (left and right), and after the light path passes through the second lens, the light path is deflected forward while being outward, so that the light source located in the middle of the vehicle can output to the target area on both sides and in front to realize illumination.

[0042] A virtual target area is arranged eccentrically below the lens, and a receiving plate 6 is arranged in the target area, and the illumination distribution after the lens combination is shown in Figure 13 As can be seen from the figure, within the diameter 300mm of the target area, the illumination value is larger and the distribution is more uniform, and the illumination effect is good.

[0043] The double-lens vehicle-mounted ceiling lamp device adopts a cup lens and a crystal block lens combined together, the cup lens mainly collects the large-angle light emitted by the light emitting diode and changes it into small-angle light, collects the emitted light close to the irradiation center and maintains a certain concentration, so that the light on the receiving surface converges into a roughly circular light spot, at the same time, surface skin treatment is performed on the light outlet surface of the cup lens to improve the uniformity of the light and eliminate the yellow light spot caused by the light source, a crystal block lens is arranged outside the light outlet, the crystal block lens collects the stray light and forms a certain lighting effect at the same time, and the overall aesthetic appearance is improved.

[0044] The side wall of the cone of the cup lens 2 is an outward convex arc surface forming a spherical surface, and the center of the spherical surface is eccentric to the geometric center of the lens.

[0045] The utility model discloses a double-lens vehicle-mounted ceiling lamp device, which is provided with a cup lens, an inclined mounting surface and a light-emitting surface, and the cup lens is attached to the circuit board in a horizontal state without the need for an inclined light source, thereby greatly improving the installation convenience, simplifying the installation structure, reducing the installation space and manufacturing cost; the arc-shaped reflecting surface is provided to cooperate with the reflection of the mounting surface, so that the light source can effectively focus the large-angle light to the light-emitting surface to form almost parallel small-angle light, and the directionality and lighting effect are good; the first light-emitting surface is provided with a skin texture treatment to improve the uniformity of the light and eliminate the yellow light spot caused by the light source, thereby enhancing the consistency and aesthetic appearance of the lighting effect; the second lens is used to deflect the direction of the light, and the deflected directions are consistent, and the light is further deflected in a specified direction and emitted to the target area; the second lens collects the stray light and forms a certain lighting effect, and the illumination distribution is uniform, and the lighting effect is good; the utility model discloses a double-lens vehicle-mounted ceiling lamp device, which is compact in structure, easy to install and good in lighting effect.
