New description: [New technology field] This creation is a telescopic lamp lens structure. In detail, it relates to a design that can accommodate a large area of aluminum substrate and increase the movement space of the lamp body relative to the lamp cover. [Prior Art] According to the telescopic lamp, it is a common lighting object currently on the market, such as a telescopic flashlight, which is a two-light tube that is mutually movable and can be changed between two lamps and one lamp. A lamp body is arranged at the end of the tube, and a convex lens is arranged at the front end of the lamp body, and the distance between the lamp body and the convex lens is changed by the mutual movement between the barrels, thereby obtaining the effect of astigmatism or concentrating, so the related industry has many There is an improvement on the structure of the telescopic lamp; of course, the most important one is the setting pattern of the convex lens and the lamp body, and the conventional telescopic lamp adopts a transparent lamp cover with a convex lens at the center of the front end and a spherical ball at the rear end, through the lamp body. The distance from the spherical portion of the transparent lampshade is changed. When the lamp body is far away from the spherical portion of the transparent lampshade, the light is refracted through the spherical portion of the transparent lampshade, and is reflected by the convex lens and the vicinity thereof through the edge of the lampshade. Out, the concentrating effect is obtained, and when the lamp body is closer to the spherical portion of the transparent lampshade, the result of the refraction and reflection is the astigmatism effect. Although this kind of provincial telescopic luminaire can obtain the effect of astigmatism and concentrating, the heat generated by the illuminating and illuminating of the lamp body is considerable, so the township system __ reduction plate and button set, with the substrate emitting light The heat generated by the body, but because the rounded spherical part of the transparent lampshade can accommodate the space of the lamp body is relatively limited, even if the spherical part is opened - a small hole, only part of the lamp body can be put into the body, so that the wire material Relatively fresh collision, or can only design a small area of silk board to overcome the above problem of insufficient space 'but the small area of the silk plate obviously can not cope with the M409384 thermal set produced by the lamp body, or as the German patent case number DE 20 2008 014 870 U1, the rear end of the lampshade is slightly removed. A small volume groove for the lamp body to enter. It can still only use a small area of the base plate, so its practicality is quite limited, and it is necessary to develop it to accommodate A larger area of the base plate and an enlarged lamp body relative to the lamp cover _ space extension test lens structure. [New content] The main purpose of this creation is to provide a lens structure for telescopic lamps, which can improve the conventional fascia lamps and lanterns, and the lamp cover knots are not designed to be over-sized, so that the title and the woven plate are not enough. In order to achieve the above objects and effects, the lens structure of the telescopic lamp comprises a lamp cover body in which the front end of the lamp cover body is recessed inwardly, and a chamber is formed, and a cone surface is arranged on the peripheral wall of the through-out chamber, and the cone has an inner diameter. Decreasing, and a convex lens is arranged in the inner center of the cone surface, and the outer circumference of the lamp cover is provided with a beveled taper portion. The tapered taper portion is gradually reduced in diameter toward the rear end of the lamp cover body, and the end portion of the inclined taper portion is cut, and the center of the vertical cut surface is set - The nanopore has a thickness of d, the thickness of the lamp body is d, and the maximum length of the nanopore is £ 'the length of the aluminum substrate is L, where dgj), [> £. The hole of the creation is tapered, and its diameter is gradually reduced from the opening. Therefore, the end of the creative and conventional technology is not the same as the shape of the spherical structure. The vertical cutting surface enlarges the space where the lamp body and the is substrate are close to each other, so that the lamp system can enter the hole and make the hole system The larger area of the substrate is close to the nanohole', so that the space where the lamp body can be close to the lamp cover body becomes larger, and the larger area _substrate can be used to provide a larger astigmatism effect, and the larger area of the is substrate is It can effectively dissipate the heat generated by the energization of the lamp body. Therefore, this creation can be said to be a kind of practical and progressive creation, which is quite worthy of promotion by the industry and publicized to the public. M409384

As shown by the first and second circles, the light shield body ι is dish-shaped. 'The front end of the permeation chamber u is recessed inwardly, and the miscellaneous surface (1) of the peripheral wall of the permeation chamber u is in a shape of 7 and exhibits a decreasing diameter from the opening of the permeation chamber η, and is in a tapered surface. And a convex lens 112, thereby forming a region for refracting light at the front end of the lamp cover body, and providing the effect of collecting or astigmatizing light when the light lens is refracted by the convex lens 112 and the tapered surface 111. (4) After the refraction and reflection of the ΐ2, 知u, and then the outer cavity of the illuminating chamber u, the outer circumference of the lampshade body 1 is set to _ oblique taper 12, and the diameter of the slanted taper portion ι2 toward the rear end of the lampshade body 1 is gradually reduced. As shown in the first and second figures, the rear end of the lampshade body 1 is provided with the inclined taper portion 12, and the front end of the lampshade body 1 is recessed and provided through the chamber 11, and the rear end is The tapered portion 12 is formed in a shape, and the tapered portion 12 is gradually reduced in diameter toward the rear end of the shade body 1, so that when the light enters the rear end of the shade body i, the light hits the inner surface of the inclined taper portion 12 to be reflected to the tapered surface 111. Or the convex lens (4), and the tapered cone 12 is tapered to the rear end of the lamp body 1 to reduce the direction of the light reflection, so that the light can be surely reversed, 111, _戦, w The end portion of the inclined taper portion 12 is a central portion 121. The center of the vertical cut surface 121 is provided with a nanohole 122. The thickness of the nanohole 122 is d, the thickness of the lamp body 2 is D, and the maximum length of the nanometer is £ The length of the reduced plate 3 is L, where gamma, L > £, and the shaft hole 122 is tapered, and its diameter is gradually reduced from the opening (this is the optimal ratio of the implementation of the creation, mainly to the lamp body 2 5 M409384 can be surely entered into the nanohole 122, and the aluminum substrate 3 is also allowed to be closer to the nanohole 122). As shown in the first and second figures, the end of the inclined taper 12 is vertically cut out from the vertical cut surface 121. And the nanohole 122 is opened in the center of the vertical cutting surface 121, so it is not the same as the type of the spherical structure in the rear end of the conventional technology, and the vertical cutting surface 121 is added. The lamp body 2 and the substrate 3 are moved closer to each other, so that the lamp body 2 can enter the hole 122 and the larger area of the aluminum substrate 3 is close to the hole 122, so that the lamp body 2 can be close to the lamp body 1. When the size is increased, a large area of the aluminum substrate 3 can be used. In addition to providing a large astigmatism effect, the larger area of the substrate 3 can effectively dissipate the heat generated by the energization of the lamp body 2. As shown in the third figure, the lamp body 2 and the aluminum substrate 3 are away from the lamp body ( (the lamp body 2 of the telescopic lamp is close to the lamp cover 1 and away from the technical system is a conventional structure, and as in the prior art Taking the telescopic flashlight as an example, it can be seen that the structure of the telescopic lamp can be implemented, but it should be noted that this creation can be implemented on other types of telescopic lamps, because the focus of this creation is on the structure of the lamp body to increase the body of the lamp. 2 Relative to the shade body _ space _ space, so the details of the telescopic luminaires will not be described. The lamp body 2 is made up of fresh 丨 魏 Wei people (played inside Nakon 122), the light passes through the slant The reflection on the inner surface of the tapered portion 12 is directed toward the convex surface u (the direction of the convex lens (1). At this time, the reflection of the light and the reflection of the exiting chamber u appear in a concentrated form; (when the light is made of a light-tight medium (the refractive index η is relatively large) When the medium enters the light-dissipating medium (the medium with a relatively small refractive index) (for example, the water is incident on the air), if the incident angle 仏 is equal to a certain angle, the refracted light will follow the tangent of the refractive interface, that is, the angle of refraction. 02=9 degrees, there will be sin (four), then It can be pushed to K = _ but if the incident angle Α is greater than the inverse one value ~, the sine sin~>n2/ni of the incident angle will be pushed to 』2>1. _There is no intention to lie, so this time , there is no refracted light, only 6 M409384

The minimum incident angle 0C at which total internal reflection occurs is called the critical angle, and its value depends on the ratio of the refractive indices of the two media, that is, (9c = sin_1 (in / (1))' and the light emitted by the lamp body 2 is The inner surface of the shade body 1 is applied to the inner surface of the inclined taper portion 12, which is the use of this theory, mainly in the vicinity of total internal reflection. As shown in the fourth figure, the light body 2 and the aluminum substrate 3 are close to the shade body 1. In the embodiment, the lamp body 2 enters the nanohole 122, and the aluminum substrate 3 is relatively close to the nanohole 22, and the light emitted by the lamp body 2 is emitted from the nanohole 122 to the front end of the lamp body, and the light system is Directly hitting the convex lens 112 and exiting through the venting chamber 11, the refracting direction of the light is astigmatic mode, and most importantly, the vertical surface 121 and the nanohole 122 provide the lamp body 2 and the aluminum substrate 3 to move closer to each other. Therefore, the closer the lamp body 2 is to the convex lens 112, the more obvious the astigmatism effect, and since the movable space of the substrate 3 relative to the lamp body i is increased, it is of course possible to use a larger area _ substrate 3 instead of It is necessary to reduce the area of the recording board 3 as required by the technology, so the larger area is Plate 3 can be effectively distribute heat generated by the lamp body 2 'so that the temperature of the rear end of the globe by the body i palliative appropriate, to avoid stretching the high-temperature lamp or affect the normal lighting parts life.
