Detailed Description

(examples)

Fig. 1 to 4 show an embodiment of the present invention, wherein fig. 1 is a schematic structural view of the present invention; FIG. 2 is a schematic view of the left side of the lens plate coinciding with the left side of the light source plate in use according to the present invention; FIG. 3 is a schematic view of the left side of the lens plate coinciding with the right side of the light source plate when the present invention is in use; FIG. 4 is a sectional view of the present invention. In this embodiment, the left isotropic word is only for convenience of description and is not limited.

Referring to fig. 1 to 3, a ceiling lamp lens module of variable light-emitting angle, includes light source board 1, equidistant lamp pearl 2 that is fixed with on the light source board still is provided with lens board 3, evenly be fixed with lens body 4 on the lens board, in this embodiment, lens board and lens body are PMMA or PC structure, and the lens body is the central axis symmetry setting. The utility model discloses a lens, including light source board, buckle hole 5, locating convex column 6, it is downthehole that buckle hole has been seted up on the light source board, the buckle hole is in between the adjacent lamp pearl and is in the left side at the line center of adjacent lamp pearl, the bottom surface integrated into one piece of lens board has locating convex column 6, and it is shown in figure 1, when the left side of lens board and the left side of light source board were unanimously installed, locating convex column card is gone into the buckle is downthehole, and the lens board is attached on the top surface of light source board and the lamp pearl is in lens body this moment, as shown in figure 2. In this case, it is a common usage. In the practical application process, the downward extending length of the peripheral edge of the lens plate is more than or equal to 0.5mm, and the lens plate is wrapped to prevent the lens and the LED plane from deviating.

When the installation is pressed close to on the left side of lens board and the right side of light source board, the location projection supports and presses and makes to have a clearance between lens board and the light source board the top surface of light source board, just the lamp pearl is in under the lens body, as shown in fig. 3, because location projection and buckle hole are in the inclined to left side of the central line of adjacent lamp pearl, so when the lens board trades the direction installation, the location projection has staggered with the position in buckle hole mutually, so after the installation, has a clearance between lens board and the light source board, and the height in clearance is the height of location projection, and the lamp pearl is under the lens body this moment. After the lens plate is installed in the forward direction or the reversing direction, the distance between the lamp beads and the lens body is adjusted, so that the light emitting angle of the lamp beads is changed through the light emitting angle of the lens body, and the adjustment of the light emitting angle is realized.

In the practical application process, the free-form surface refers to a curved surface which has the random characteristics of traditional machining and forming and the surface shape of which cannot be continuously machined. The outer optical surface 41 of the lens body 4 is a free curved surface with a concave center, the inner optical surface 42 of the lens body includes a lower inner optical surface 421 and an upper inner optical surface 422, and the lower inner optical surface is a free curved surface. As shown in fig. 4, in practical application, the upper internal optical surface is a free-form surface or an elliptical surface, a conical surface or a parabolic surface. And in the practical application process, the central axis range of the light of the lamp bead passing through the contact point between the upper inner optical surface and the lower optical surface is 60-80 degrees. Thereby distinguishing the upper internal optical surface and lower optical panel positions by this central axis range,

the structure of the utility model is reasonably arranged, the left side of the lens plate is coincided with the left side of the light source plate, or the left side of the lens plate is coincided with the right side of the light source plate, and the positioning convex column is matched with the buckling hole, so that the lens plate is attached to or a gap is reserved between the lens plate and the light source plate, the light emitting angle of the lamp beads is adjusted through the lens body, the utility model can match the use requirements of ceiling lamp shades with different heights, greatly improves the application range of the lens module, simultaneously can ensure that the lamp shades with different heights can keep consistent lamp shade illumination and light color uniformity when in use, enhances the universality of the lens module, and has strong applicability and good practicability.
