Description

Lighting fixture with lampshade module having replaceable optical projection assembly

Technical Field

The invention relates to a lamp shade, in particular to a lamp shade used for being combined in front of a light emitting module of a lamp, and capable of changing the light projection angle through lenses respectively embedded in a lens seat and corresponding to light emitting diodes.

Background Art

Take the current LED projection light as an example. It mainly has a light module. The front side of a substrate of the light module is encapsulated with a number of light emitting diodes (LEDs) in a circular array. In order to set the light projection angle, an optical lampshade is usually assembled in front of the light module. The optical lampshade mainly has a lens seat made of one-piece plastic molding. The back side of the lens seat is integrally molded with several protruding lens parts. The center of the lens part has a light-incoming surface, which directly faces the light-emitting surface of the front side of the lens seat. In this way, the light-emitting diodes of the light module are respectively aligned with the light-incoming surface of the lens part, so as to achieve the effect of setting the light projection angle of the lamp.

However, different light projection angles are required for different applications of projection lamps, so a variety of optical lampshades must be manufactured. The lens structure of each optical lampshade is slightly different, and then the optical lampshade with the required angle is selected and assembled in front of the light-emitting module. For example, the first projection lamp is 30˚, the second projection lamp is 60˚, and so on, so that consumers can choose. However, once the size, shape, light-emitting module structure or position of the light-emitting diode of the lamp is slightly changed, the mold must be re-made to manufacture the corresponding optical lampshade. This will affect the entire system, resulting in an increase in the manufacturing cost of many optical lampshades, and the sales channels have to stock many lamps with different angles, which will cause inventory pressure. In addition, changing the optical lampshade to a replaceable structure will also cause the problem of rainwater seeping into the gap during reassembly. Therefore, how to improve the shortcomings of conventional optical lampshades is the subject that the present invention actively aims to overcome.

Summary of the invention

The purpose of the present invention is to provide a lighting fixture with a lampshade module having a replaceable optical projection component. The lighting fixture can easily provide a variety of different light projection angles through the combination structure of a lens holder and a plurality of lenses. The lens holder and the lenses can be easily replaced, which can reduce manufacturing costs, alleviate inventory pressure on sales channels, and prevent rainwater from seeping in.

In order to achieve the above-mentioned purpose, the lampshade module of the replaceable optical projection assembly of the present invention is used to be combined with a lamp to adjust the light projection angle of a light emitting diode (LED). The preferred technical solution thereof includes:

A lens holder, a front side of which is provided with a plurality of lens holes, the lens holes being holes recessed from the front side toward a bottom side of the lens holder, the rear end of the lens holes being used to correspond to the light emitting diodes of the lamp; a hole wall of the lens holes is provided with a first latching portion, the first latching portion being used to latch a lens pushed into the lens hole; and

The lens embedded in each lens hole is a light-transmitting lens having a light-incoming surface and a light-outgoing surface opposite to the light-incoming surface; the light-incoming surface is a convex arc surface protruding toward the direction of the light-emitting diode, and the convex arc surface is used to generate a light projection angle after the light of the light-emitting diode enters; and a second latch portion is formed around the lens, and the second latch portion is used to latch and fix the first latch portion of the lens hole.

One of the better solutions of the lampshade module of the replaceable optical projection assembly is that a rear end surface of the lens opposite to the light emitting surface forms a groove concave toward the light emitting surface, and the light entering surface is formed at the bottom of the groove.

In one of the better solutions of the lampshade module of the replaceable optical projection assembly, the curvature of the convex arc surface of each lens is different, so as to generate different light projection angles.

In one of the better solutions of the lampshade module with replaceable optical projection assembly, the light projection angle is any angle between 5° and 120°.

In one of the better solutions of the lampshade module of the replaceable optical projection assembly, the bottom surface of the lens seat is a plane, and the bottom surface is used to abut against the light emitting diode.

In one of the better solutions of the lampshade module of the replaceable optical projection assembly, the bottom surface of the lens seat is respectively provided with a receiving hole corresponding to the lens hole, and the receiving hole is used to accommodate the light emitting diode.

In one of the better solutions of the lampshade module of the replaceable optical projection assembly, the plurality of lens holes include a central point formed on the front side of the lens seat, and a plurality of lens holes surrounding the central point.

In one of the better solutions of the lampshade module of the replaceable optical projection assembly, the first latch portion is a protruding portion horizontally protruding from the wall of the lens hole.

In one of the better solutions of the lampshade module of the replaceable optical projection assembly, the second latching portion is a recessed buckle portion horizontally recessed from the periphery of the conical arc surface, and the recessed buckle portion is latched and fixed to the protruding buckle portion.

The lampshade module of the present invention, which can replace the optical projection assembly, can be assembled and applied in front of the light-emitting module of lamps such as projection lamps, track lights, garden lights or wall lamps, so that the light-incoming surface of each lens corresponds to the light-emitting diode (LED) on the light-emitting module, and the light projection angle of the lamp is changed by the different curvatures of the light-incoming surfaces of each lens. When the manufacturer has a specific light projection angle requirement, as long as the lens of the required angle is replaced in the lens holder, a lamp with a specific light projection angle can be immediately provided; and even if the size, shape, light-emitting module structure or position of the light-emitting diode of the lamp is slightly changed, only a new lens holder needs to be remade, and the lens does not need to be remade, and it can be combined with the existing lens for application; furthermore, the lens hole of the lens holder of the present invention is a concave hole, and the lens is provided to be embedded in the concave hole, and rainwater will not penetrate from the lens hole. Therefore, the present invention can easily provide lamps with a variety of different light projection angles, can easily replace the lens holder and the lens, and can reduce manufacturing costs, reduce inventory pressure in sales channels, and prevent water infiltration.
