Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
As shown in fig. 1 and 2, a lens 100 for a lighting fixture of the present application includes a lens body 101, and a collimating part 1 and a first reflecting surface 2 respectively provided on the lens body 101. The lens body 101 is provided with opposite first and second ends. The collimating part 1 is disposed at a first end of the lens body 101, and receives light emitted from a light source 200 (shown in fig. 3) of the lighting fixture, and directs the light emitted from the light source 200 to the first reflecting surface 2. The first reflecting surface 2 is provided at the second end of the lens body 101, and reflects the light from the collimator 1 to the side wall of the lens body 101.
The collimator 1 serves to convert light emitted from the light source 200 into parallel light so as to control a transmission path of the light. After being collimated by the collimator 1, the light directed to the first reflecting surface 2 is substantially parallel to the axis of the lens body 101.
In the first embodiment, as shown in fig. 1 to 4, the collimator 1 includes an annular light source accommodating groove 11. The light source receiving groove 11 includes a concave surface 12 at an upper end, and a sidewall 13 at a side of the concave surface 12. The light passing through the concave surface 12 becomes parallel light. The concave surface 12 is a rotation surface formed by rotating an arc around the center of the lens body 101 (the center of the lens body 101 is located at the middle of the horizontal cross section of the lens body 101), wherein a space is reserved between the first end of the arc (the end close to the center of the lens body 101) and the center of the lens body 101 along the horizontal direction (the direction perpendicular to the axis of the lens body 101) and away from the center of the lens body 101, i.e. along the horizontal direction. The arc may be a circular arc or an elliptical arc. The spacing between the first end of the arc and the center of the lens body 101 may be set as desired. The length of the arc may be set according to the size of the light source 200.
The light source 200 provided in the light source accommodation groove 11 may be an LED (LIGHT EMITTING Diode) light source 200. A plurality of LED light sources 200 are disposed at intervals in the light source accommodating groove 11, the plurality of LED light sources 200 are annularly arranged around the center of the lens body 101, and the center of each LED light source 200 is located at the center of an arc.
Through the arrangement of the mode, on the basis of ensuring convenience in light control, the light sources 200 can be distributed in a scattered manner, so that the heat dissipation effect is good, and the power of the lighting lamp can be ensured.
The side wall 13 now comprises an inner side wall 131 located inside the concave surface 12 and an outer side wall 132 located outside the concave surface 12. The inner side wall 131 and the outer side wall 132 each surround the center of the lens body 101, and the inner side wall 131 and the outer side wall 132 may each be a light-transmitting side wall. The collimating part 1 now further comprises a second reflecting surface 14. The second reflecting surface 14 includes a second inner reflecting surface 141 located between the light source accommodating groove 11 and the center of the lens body 101, and a second outer reflecting surface 142 located between the light source accommodating groove 11 and the side wall 13 of the lens body 101. The second internal reflection surface 141 reflects the light emitted from the inner sidewall 131 to the first reflection surface 2 as parallel light. The second outer reflecting surface 142 reflects the light emitted from the outer side wall 132 to the first reflecting surface 2 as parallel light. The second inner reflecting surface 141 and the second outer reflecting surface 142 are relatively easily provided with respect to the inner side wall 131 and the outer side wall 132 of the light source accommodating groove 11, so that light emitted from the inner side wall 131 and the outer side wall 132 is converted into parallel light.
The second inner reflecting surface 141 and the second outer reflecting surface 142 may be provided in various ways, and in one example, the second inner reflecting surface 141 and the second outer reflecting surface 142 are total internal reflecting surfaces. Total internal reflection is also known as total reflection ((total internal reflection TIR) when light enters a medium of lower refractive index from a medium of higher refractive index, if the angle of incidence is greater than a certain critical angle, the refracted light will disappear and all incident light will be reflected without entering a medium of lower refractive index.
More specifically, the second internal reflection surface 141 may be a tapered surface opened toward the first end, and is formed by rotating an arc shape around the center of the lens body 101. The second external reflection surface 142 is a frustum surface, and the frustum surface is formed by rotating an arc around the center of the lens body 101, wherein the opening of the frustum surface towards the first end of the lens body 101 is small, and the opening towards the second end of the lens body 101 is large. So arranged, the second inner and outer reflective surfaces 141 and 142 are conveniently machined such that the second inner and outer reflective surfaces 141 and 142 form a total internal reflection surface.
Of course, the second inner reflecting surface 141 and the second outer reflecting surface 142 may not be total internal reflecting surfaces, but reflective materials or the like may be plated on the outer sides of the second inner reflecting surface 141 and the second outer reflecting surface 142.
The first reflective surface 2 may also be a total internal reflection surface. The first reflecting surface 2 is a conical surface with an opening facing the second end of the lens body 101, and is formed by rotating a straight line around the center of the lens body 101, and one end of the straight line is located on the center of the lens body 101 so as to facilitate light control. The light reflected from the first reflecting surface 2 is substantially perpendicular to the axis of the lens body 101.
The light receiving side wall 3 of the lens body 101 (the light receiving side wall 3 is used for receiving the light reflected by the first reflecting surface 2) may be formed by alternately connecting a plurality of refractive surfaces 32 and a plurality of third reflecting surfaces 31 from the second end to the first end of the lens body 101 (or, in other words, along the axial direction of the lens body 101). The light emitted from each refractive surface 32 and each third reflective surface 31 is deflected toward the first end and located in a different region.
By the arrangement, when the lens 100 is used for the illumination lamp, the lens 100 can realize the lower light emission of the illumination lamp; large-angle deflection (deflection towards the first end of the lens body 101) can be realized through the third reflecting surface 31, small-angle deflection can be realized through the refracting surface 32, and the light-emitting area of lower light emission is increased; the shape of each third reflective surface 31 may be set to be the same, and the shape of each refractive surface 32 may be set to be the same, improving the aesthetic appearance, to use the lens 100 as a part of the lighting fixture housing.
Along the axial direction of the lens body 101, the inclination angle of the third reflection surface 31 is large, and the inclination angle of the refraction surface 32 is small, so that the large-angle deflection is realized by the third reflection surface 31, and the small-angle deflection is realized by the refraction surface 32. The refractive surface 32 is recessed toward the inside of the lens body 101 with respect to the third reflective surface 31 to prevent the refractive surface 32 from blocking the light reflected from the third reflective surface 31.
In the second embodiment, as shown in fig. 5 to 7, the collimating part 1 'includes a light source accommodating groove 11'. The light source receiving groove 11' includes a concave surface 12' at an upper end and a sidewall 13' at a side portion. The light passing through the concave surface 12' becomes parallel light. The concave surface 12' is a rotation surface formed by rotating an arc around the center of the arc, and the arc is far away from the center of the lens body 101 in the horizontal direction, i.e., a space is left between the first end of the arc (the end close to the center of the lens body 101) and the center of the lens body 101 in the horizontal direction. The arc may be a circular arc or an elliptical arc. The spacing between the first end of the arc and the center of the lens body 101 may be set as desired. The length of the arc may be set according to the size of the light source 200.
Around the center of the lens body 101, a plurality of light source receiving grooves 11 'are provided at intervals, for example, at least five light source receiving grooves 11'. The shape and size of each light source receiving groove 11' are the same. Each light source receiving groove 11 'is provided with a separate sidewall 13'.
The light source 200 disposed in the light source receiving groove 11' may be an LED light source 200. One LED light source 200 is provided in each light source accommodating groove 11', and each LED light source 200 is provided at the center of the light source accommodating groove 11', respectively.
Through the arrangement of the mode, on the basis of ensuring convenience in light control, the light sources 200 can be distributed in a scattered manner, so that the heat dissipation effect is good, and the power of the lighting lamp can be ensured.
The side wall 13' of the light source receiving groove 11' surrounds the concave surface 12', and the side wall 13' is a light-transmitting side wall 13'. The collimating part 1' now further comprises a second reflecting surface 14' surrounding the concave surface 12 '. The second reflecting surface 14 'reflects the light emitted from the side wall 13' to the first reflecting surface 2 as parallel light.
The second reflective surface 14 'can be provided in a variety of ways, and in one example, the second reflective surface 14' is a total internal reflection surface. More specifically, the second reflecting surface 14' is a conical surface, and the conical surface ' has a small opening toward the first end and a large opening toward the second end, and is formed by rotating an arc around the center of the light source accommodating groove 11 '. This arrangement facilitates processing of the second reflective surface 14 'such that the second reflective surface 14' forms a total internal reflection surface.
Of course, the second reflecting surface 14 'may be a reflecting layer formed of a reflecting material, instead of the total internal reflection surface, by plating a reflecting material on the outer side of the second reflecting surface 14'.
The first reflecting surface 2 and the light receiving side wall 3 are configured in the same manner as the first reflecting surface 2 and the light receiving side wall 3 in the first embodiment, and will not be described here again.
The lens 100 may be a plastic lens 100, either of the first embodiment or the second embodiment, to enable the lens 100 to be exposed as part of the light-emitting mask 400. Of course, the lens 100 may be a glass lens 100 or the like.
The lighting module of the present application includes a lens 100, a light source 200 disposed in a light source accommodating groove 11 of the lens 100, and a substrate 300 for fixing the light source 200, wherein the lens 100 is the lens 100. The lighting module can ensure that the light sources 200 are distributed and dispersed on the basis of conveniently controlling the light, the heat dissipation effect is improved, and the power of the lighting lamp can be ensured.
As shown in fig. 8 and 9, the lighting lamp of the present application may be a candle bulb lamp, and the lighting lamp includes a lighting module, a light-emitting surface cover 400 above the lighting module, a base 500 below the lighting module, a driving light source 600 disposed in the base 500, and a lamp cap 700 disposed below the base 500 and electrically connected to the lighting module, wherein the lighting module is the lighting module, and the lens 100 is respectively disposed between and respectively assembled with the light-emitting surface cover 400 and the base 500. The lighting lamp can ensure that the light sources 200 are distributed in a scattered manner on the basis of ensuring convenience in light control, so that the heat dissipation effect is improved, and the power of the lighting lamp can be ensured.
The foregoing is merely exemplary of the present application and is not intended to limit the present application.
