Abstract
The invention relates to the technology field of flashlight products, in particular to a flashlight with spotlight bulb which can improve spotlighting effect and the filming process of a reflective mirror in the flashlight with spotlight bulb. The reflective mirror of the flashlight main body is in a bowl shape, and the concave surface of the reflective mirror is not smooth, and likes an orange peel. The technical proposal adopted by the filming process of the reflective mirror in the invention is that the filming process includes the following steps: (1) the reflective mirror is subjected to oil removal and dirt removal; (2) a varnish is uniformly coated on the reflective mirror and then is dried to make the orange peel shape formed on the surface film of the reflective mirror; and (3) the dried reflective mirror is subjected to vacuum deposition. Due to the adoption of the structure, firstly the concave of the reflective mirror in the invention still undergoes mirror surface processing, so as not to influence ray reflection; and secondly, after the concave is processed into the non-smooth orange peel shape of the reflective mirror in the invention, diffuse reflection is generated when the light emitted by the miniature bulb passes through the reflective mirror, so that the aureole phenomenon in the bright area is thoroughly eliminated, and the ray reflected by the reflective mirror can not be radiated, thereby improving the spotlighting effect of the product.
Description
Technical field:
The present invention relates to the flashlight product technical field, refer in particular to reflector plating technique in a kind of concentration torch that improves spotlight effect and this concentration torch.
Background technology:
Flashlight is an illuminations commonly used in daily life, the work.Usually, flashlight comprises stack shell, lamp holder and the battery that is positioned at stack shell.Lamp holder comprises a miniature bulb and a reflective concave mirror.This concave mirror is bowl-shape, and its inner surface treatment is smooth minute surface, and miniature bulb is positioned at the center of reflective mirror and is positioned at the focal position of concave mirror.According to optical principle, when miniature bulb begin luminous after, its light that sends will shine out with approximately parallel light through after reflection of concave mirror.As shown in Figure 1, reflective mirror 01 inner surface treatment becomes smooth minute surface, and the part light that miniature bulb 02 sends reflects away through the minute surface of reflective mirror 01, goes out with part light direct irradiation in addition.We can see that the regional center of flashlight irradiation has a brighter lighted region 03 (light by reflection forms).Usually this lighted region 03 can form the ring of light, because the existence of the ring of light has caused the undesirable of spotlight effect.Why produce ring of light effect, this be because, because the inner surface of reflective mirror 01 is treated smooth mirror surface, the minute surface reflection takes place by reflective mirror 01 in the light that miniature bulb 02 produces, reflection angle at the different cross section of reflective mirror (parallel) glazed thread is consistent, so after the reflection of different cross section (parallel) glazed thread, through behind the telecurie irradiation, irradiation area is exaggerated, and has so just formed the ring of light of different-diameter annular.Present flashlight can be regulated the position of miniature bulb, miniature bulb is adjusted to the focal position of reflective mirror by the rotation lamp holder, though but this can improve the spotlight effect of light, but still can't thoroughly eliminate the phenomenon of the ring of light, cause the darker ring of light zone of interior formation, zone of the illumination of flashlight, influence illuminating effect.
In addition, see that Chinese patent application number is 88219028.8 utility application specification, this patent provides a kind of total reflection high concentration torch.What this flashlight reflective mirror adopted is to be made of two different parabolic minute surfaces of radius of curvature.But adopt this structure still can't eliminate the ring of light phenomenon.
Another aspect, in order to improve the reflecting effect of flashlight, reflective mirror need pass through coating film treatment usually.Just because of of the brightness of currently used coating process, so cause the light of flashlight irradiation can form the ring of light just to the raising film.
Summary of the invention:

Traditional flashlight all is one to adopt the reflective mirror smooth, that brightness is high as far as possible, and to improve optically focused, the reflecting effect of light, still, the present invention breaks through the design of traditional flashlight, the concave surface of luminous mirror is processed into the orange peel shape of non-shiny surface.Adopt this structure, the concave surface of reflective mirror at first of the present invention still passes through mirror process, and it can not influence the reflection of light.Secondly, by after concave surface being processed into the orange peel shape of non-shiny surface, the light that miniature bulb produces produces a kind of diffuse reflection through reflective mirror, promptly the reflection angle of Fan She light is inconsistent, uneven mutually, so just thoroughly eliminated the ring of light phenomenon in the lighted region, the light that the while reflective mirror reflects away does not produce to be dispersed, and makes the spotlight effect of product more outstanding.
The technical scheme that reflector plating technique adopted among the present invention is: this coating process may further comprise the steps: one, to reflective mirror oil removing, decontamination; Two, varnish is coated on reflective mirror uniformly, Ran Hou is baked to be done, and makes the mirror surface rete form orange peel shape; Three,, the reflective mirror after baked doing carries out the vacuum coating processing.
The varnish that is adopted in the such scheme is: acrylic lacquer.
Described acrylic lacquer is methacrylate and acrylic copolymer resin.
Be coated on the surface of reflective mirror after methacrylate in the described acrylic lacquer and acrylate and the solvent.Perhaps can adopt the mode of coating respectively, methacrylate in the described acrylic lacquer and acrylate are coated on the surface of reflective mirror respectively, promptly at first at the surface of reflective mirror coating methacrylate, and carry out drying and handle, be coated with acrylate then, and carrying out drying and handle.
With the primary raw material of acrylic lacquer as film forming, the formed film of this varnish has brightness, hardness preferably, and adhesive force is good, and is firm wear-resisting.But acrylic lacquer is easy to generate the tangerine peel phenomenon easily when film forming, just in time satisfy requirement of the present invention, to eliminate the ring of light phenomenon in the flashlight lighting lighted region.
