Description

LED recessed light shade

This creation is about an optical lampshade for an LED downlight, especially an optical lampshade structure that is applied to an LED downlight to improve its lighting effect.

The conventional LED recessed lamp is used for embedding a lighting device in a ceiling, and the LED lighting module comprises a substrate and a plurality of LEDs arrayed on the substrate, and the LED has a long service life. The more energy-saving effect has gradually become the mainstream of lighting equipment. However, the light generated by the LED lighting module is excessively concentrated and directional, and the scattering effect is not good, and the irradiation range and the spot are too concentrated. If applied to indoor lighting, the better lighting effect cannot be achieved. To this end, conventional LED lighting devices will try to add an optical component in front of the lighting module to modulate the light emitted by the LED lighting module. However, how to make the light emitted by the LED recessed lamp have better scattering effect and enable uniform illumination, which is the subject to be overcome by the creation. Moreover, the lampshade of the conventional LED recessed lamp is mostly made of glass. If the plastic is used at a lower cost, the refraction and transmission effect of the light will be affected, which is also a problem that needs to be solved in this creation.

The purpose of this creation is to provide an LED recessed light optical lamp The cover is improved by the refractive structure of the optical lamp cover, and the light source of the LED downlight is changed, thereby achieving better scattering effect and uniform spot.

In order to achieve the above object, the preferred technical content of the optical lamp cover of the LED recessed lamp includes: an optical lens having a first side and an opposite second side; the first side has a LED for bonding to the LED a convex ring of the recessed lamp, the first side of the first ring forming a first convex arc surface, the first convex arc surface corresponding to the LED light source; the second side forming a second convex arc surface The second convex arc surface projects the light of the LED light source.

The optical lamp cover of the LED recessed lamp according to the above preferred technical content, wherein the first convex arc surface and the second convex arc surface have an arc of π/4 π π/6.

The optical lampshade of the LED recessed lamp according to the above preferred technical description, wherein the distance between the first convex arc surface and the apex of the second convex arc surface is 1/7~1/ of the radius of curvature of the convex arc surface 9.

The optical lamp cover of the LED recessed lamp according to the above preferred technical description, wherein the periphery of the convex ring forms a ring plane, and the periphery of the second convex arc surface is connected to the outer edge of the ring plane.

The optical lamp cover of the LED recessed lamp according to the above preferred technical content, wherein the convex ring has a joint portion coupled to the LED recessed lamp.

The optical lampshade of the LED recessed lamp according to the above preferred technical content, wherein the convex ring is a ring.

The optical lamp cover of the LED downlight according to the above preferred technical content, wherein the joint protrudes from the outer ring surface of the convex ring.

The optical lamp cover of the LED recessed lamp can be screwed into the body of the LED recessed lamp by the thread of the outer ring surface of the convex ring, and the bottom surface of the LED embedded lamp is covered, and the first convex arc surface of the optical lens corresponds to the LED light emitting mode. Therefore, the light of the LED lighting module is configured by the lenticular lens to obtain a better scattering effect outside the focal length, and the illumination on the floor or the surface of the object can obtain a more uniform spot.

The structural features and other functions and purposes of the present invention are described in detail below with reference to the accompanying drawings: as shown in the first, second and third figures, the present LED The preferred embodiment of the recessed optical lamp cover comprises an optical lens 1 for being integrated into the LED downlight 2, the optical lens 1 being formed by transparent glass or plastic integrally formed or combined, which has a first a side 11 and an opposite second side 12, wherein: as shown in the third to fifth figures, the first side 11 has a convex ring 13 for being coupled to the LED recessed lamp 2, the first side 11 A first convex arc surface 14 is formed at the bottom of the concave hole 131 in the convex ring 13, and the first convex curved surface 14 preferably has a curvature of π/4~π/6. When the optical lens 1 is mounted on the LED recessed lamp 2, The first convex arc surface 14 is corresponding to the LED lighting module 21; the second side 12 is formed with a second convex arc surface 15, and the second convex arc surface 15 preferably has a curvature of π/4~π/6, and the first The distance d (thickness) between the convex surface 15 and the apex of the first convex curved surface 14 is preferably 1/7 to 1/9 of the radius of curvature of the first convex curved surface 14 or the second convex curved surface 15, The best is 1/8, whereby the second convex arc surface 15 can project the light of the LED lighting module 21.

Further, as shown in the third to fifth figures, the periphery of the convex ring 13 of the optical lens 1 is formed with a ring plane 16 , and the periphery of the second convex curved surface 15 is preferably connected outside the ring plane 16 . Thus, the edge of the optical lens 1 (the portion of the ring plane 16) can be used to cover the entire LED downlight 2 (as shown in the second figure), so that the LED downlight installation is more beautiful. Furthermore, the convex ring 13 is preferably a ring having a joint portion 132 coupled to the LED recessed lamp 2 at a selected portion thereof. Preferably, the outer ring surface of the convex ring 13 is provided with a thread to form the joint portion 132. Therefore, it is possible to directly screw the LED downlight 2 with a thread.

As shown in the first and second figures, this creation can select LEDs. The inner surface of the housing 22 of the recessed lamp 2 is provided with two or more engaging portions 23, preferably three engaging portions 23 as shown, and the engaging portion 23 can be formed by the stamping housing 22. The bumps are such that the joint portion 132 of the outer ring surface of the convex ring 13 can be locked to the engaging portion 23, and the joint portion 132 of the convex ring 13 can be changed to another structure, for example, the outer ring of the convex ring 13 The L-shaped groove is formed on the surface, and can be easily coupled to the engaging portion 23 of the LED downlight 2.

As shown in the sixth figure, when the optical cover of the present invention is used, the engaging portion 132 (thread) of the protruding ring 13 is screwed into the engaging portion 23 of the casing 22 of the LED recessed lamp 2, so that the first convex curved surface is formed. 14 corresponds to the LED lighting module 21, and the second convex arc surface 15 and the ring plane 16 portion can cover the entire LED recessed lamp 2. When the LED lighting module 21 emits light, the light can be refracted twice by the first convex arc surface 14 and the second convex arc surface 15, so that the light forms a better scattering angle at a portion other than the focal length f, thereby overcoming the irradiation range. The problem of excessive concentration increases the range of illumination of the LED downlight 2, and the spot that is illuminated on the floor or object is more uniform.

In summary, the optical lampshade of the LED recessed lamp has been practical and creative, and its technical means are also novel and undoubted, and the efficacy and design purpose are in line with the fact that it has been reasonably improved. To this end, a new type of patent application is filed in accordance with the law, but the bureau is requested to give a detailed examination and grant the patent as a prayer.
