Abstract

The utility model relates to a bulb, in particular to a color-changing lamp with a refraction lampshade. A group of luminous bodies or a plurality of groups of luminous bodies are inserted on a connecting plate. The upper surface of the connecting plate is provided with concave-convex parabola-shaped refraction cavities. A refraction cover is covered in a lamp cap, and is sealed and contained with a lamp body which is sealed and contained in the lamp cap. The integral bulb shell realize luminescence by means of the refraction cover in the bulb shell to reflect a light source. A particular lamp cap and a lamp holder are matched with the utility model to lead the utility model to change colors by means of a controller.

Description

Color-changing lamp with refraction lampshade

The utility model relates to a kind of bulb, particularly a kind of allochroic bulb that has the refraction cover.

The application that Chinese patent 92210048.9(proposes, grant patent) disclosed " a kind of allochroic bulb ", be to utilize the principle of three primary colours in the colorimetry, red, blue, green three-color light-emitting body is placed in the glass bulb of frosted reflection, be equipped with specific lamp cap and lamp holder again, make it the same with common bulb convenient when installing and using, by a controller can make its continuously jump or static send various photochromic.Glass bulb the latter half of this bulb is coated with the reflector layer of adularescent, therefore has only in the very little angle in front and can observe its color, does not then observe from the side, so just makes its range of application be restricted the demand that can not satisfy in multiple occasion.

The purpose of this utility model is: the three-color light-emitting body is placed in the refraction cover of cell-shell, by refraction cover in the cell-shell light source is reflected, realize that whole cell-shell is all luminous, be equipped with specific lamp cap and lamp holder again, make its variable color by controller.

The purpose of this utility model realizes by following measure:

It is made up of lamp housing, refraction cover, luminous element, reflection cavity, connecting plate and lamp holder and control circuit, be plugged with one group or array luminous element on the described connecting plate, the upper surface of connecting plate is equipped with concavo-convex parabolic reflection cavity, the refraction cover is buckled in the lamp holder and encapsulates with lamp housing, and lamp housing is encapsulated in the lamp holder; The refraction cover can be designed to triangle, semicircle, cylindrical shape and multiple geometrical body, and its inside and outside surface design is become rough refraction graininess; The metal tap correspondence of luminous element is welded on the contact of lamp holder.

Advantage of the present utility model and effect are:

One, because the three-color light-emitting body is loaded in separately the refraction cover chamber, and put in the lamp housing neck, all light reflections or direct projections are to the lamp housing top, so make its brightness raising; Place because of luminous element in the refraction cover of neck, thus the latter half of lamp housing needn't be coated with the reflector, thereby make lamp housing omnibearing luminous, increased the scope of application.

Two, lamp housing and the adhesion of refraction cover are airtight, thereby prevent that airborne moisture content and dust from entering luminous element, prevent the transparent and brightness reduction of frosted layer of cell-shell, have prolonged the useful life of bulb.Improved the quality of bulb.

Description of drawings is as follows:

Fig. 1 is the utility model overall structure cutaway view;

Fig. 2 is one of the utility model refraction cap assembly figure;

Fig. 3 is two of the utility model refraction cap assembly figure;

Fig. 4 is three of the utility model refraction cap assembly figure;

Below in conjunction with the accompanying drawing illustrated embodiment the utility model is described further:

The utility model comprises lamp housing 1, three-color light-emitting body 3, reflection cavity 4, refraction cover 2, multiconductor lamp holder 6 compositions, three-color light-emitting body 6 triplets or many groups clocklike are arranged in the reflection cavity 4, with the luminous element of same color and be cascaded, be contained on the connecting plate 5, be welded on the multiconductor lamp holder 6, and become air-tight state after lamp housing 1 is bonding.Lamp housing is a mist light, the transparent body of frosted, and shapes such as its shape can the side of being designed to, circle, ellipse, pipe, fan, awl, candle, lamp housing 1 is with the 2 bonding or burn-backs of refraction cover, in case moisture content and dust enter.The refraction cover is to make with glass or plastics, and the surface can be designed to faceted pebble, multiaspect, semi circular surface and irregular curved surface, the transparent cover that one or more mix.Controller circuitry can adopt program control, music control type, also can adopt control modes such as mechanical and touch.

Lamp housing 1 can adopt the ordinary incandescent lamp shell, inner through the frosted processing, refraction cover 2 adopts the transparent bodies such as glass or plastics to make, with 1 airtight connection of lamp housing, refraction cover can be made into shapes such as Fig. 2, Fig. 3, Fig. 4, and reflection cavity 4 is formed by metal stamping or glass, ceramic membrane, and luminous element 3 is placed in the reflection cavity 4, its light is reflexed on the refraction cover, be evenly arranged on the cell-shell 1 through reflection, refraction.Three-color light-emitting body 3 can be selected commercially available colored vesicle or the special three primary colors vesicle of making for use, adopts one or more groups according to the requirement of power, with this line parallel of identical luminous element, be cascaded and connecting plate 5 joins, is welded on the lamp holder 6.Lamp holder 6 is a kind of multiconductor lamp holders, is equipped with specific lamp socket again, realizes the variable color purpose by controller.
