Abstract

The utility model discloses an light-focusing structure of a lamp, which comprises a lampshade, an optical unit and a luminophor, wherein, the optical unit is arranged at the open end of the lampshade; an light-focusing part formed by a plurality of adjacently arrayed zigzags is arranged on one surface of the optical unit in a ring shape; and the luminophor is arranged in the lampshade and corresponding to the other surface of the optical unit. Therefore, a divergent light source emitted by the luminophor can use the light-focusing part of the optical unit to conduct total reflection (refraction), so as to achieve the effect of increasing the irradiation brightness.

Description

The concentration structure of light fixture

Technical field

The utility model is about a kind of concentration structure of light fixture, refer to especially a kind of diversity light source that illuminator is sent utilize the light collecting part of optical unit be all-trans (folding) penetrate, and reach the effect that increases irradiation brightness.

Background technology

At present, general habitual light fixture is made of cover body and the illuminator be located in the lampshade usually; Whereby, the light source of illuminator directly or after the cover body reflection is penetrated, carry out required illumination.

Though above-mentioned habitual light fixture can carry out required illumination; But because this light fixture only is made of lampshade and illuminator, and there is no any structural design on this lampshade for light source reflection, optically focused, therefore, when it uses as illumination, regular meeting is because the illumination characteristic of illuminator, concentrate and make light source scattering everywhere can't effectively carry out light source, and a little less than causing emitted light source, and have light source to scatter to carry out the situation of cover; Needs when therefore, general habitual light fixture can't realisticly use.

The utility model content

In view of this, main purpose of the present utility model is to provide a kind of concentration structure of light fixture, the diversity light source that this illuminator is sent utilize the light collecting part of optical unit be all-trans (folding) penetrate, and reach the effect that increases irradiation brightness.

In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of concentration structure of light fixture, and it includes:

Lampshade;

Optical unit, described optical unit is located at the openend of described lampshade, is equipped with the light collecting part that is formed by most the adjacent arrangements of zigzag on the one side of described optical unit; And

Illuminator, described illuminator is located in the described lampshade, and corresponding with described optical unit another side.

Adopt the beneficial effect after the technique scheme to be: the diversity light source that the concentration structure of light fixture of the present utility model can make this illuminator send utilize the light collecting part of optical unit be all-trans (folding) penetrate, and reach the effect that increases irradiation brightness, and then make the utility model can more progressive, more practical, more meet user's demand.

The specific embodiment

Below in conjunction with accompanying drawing specific embodiment in the utility model is described in further detail.

See also Figure 1 and Figure 2, be respectively the profile status schematic diagram of the concentration structure of light fixture in the three-dimensional appearance schematic diagram of concentration structure of light fixture in the utility model and the utility model.As shown in Figure 1, 2, the concentration structure of a kind of light fixture of the present utility model, it is made of lampshade 1, optical unit 2 and illuminator 3 at least.

The inner face of above-mentioned lampshade 1 is provided with reflecting surface 11.

Optical unit 2 is located at the openend of lampshade 1, and this optical unit 2 can be the printing opacity refraction material of bright or cloudy surface, form light collecting part 21 and be equipped with on the one side of this optical unit 2 by most the adjacent arrangements of zigzag, and the angle of light collecting part 21 drift angles is between 90 °-140 °, and is best angle with 120 °.

Illuminator 3 is located in the lampshade 1, and corresponding with optical unit 2 another sides.Illuminator 3 can be helical bulb or LED.Therefore, constitute the concentration structure of brand-new light fixture by said structure.

See also shown in Figure 3ly, be the reflective condition schematic diagram of the concentration structure of light fixture in the utility model.And cooperate Fig. 1, Fig. 2 referring to, shown in each figure: when the utility model in when utilization, launch light source by illuminator 3, directly or by the reflecting surface 11 in the lampshade 1 direction toward optical unit 2 penetrates to make light source, after allowing light source via light collecting part 21 refractions, penetrate optical unit 2 outsides with the total reflection state, therefore, when the light source of illuminator 3 penetrates optical unit 2, the state that can utilize the light collecting part 21 of optical unit 2 to penetrate be all-trans (folding) is assembled light source, and the brightness when making these illuminator 3 irradiations obtains increasing.

The above is a preferred embodiment of the present utility model only, is not to limit claim of the present utility model in order to this; Equivalence that all utilization the utility model claims and description are done changes and modifies, and all should still belong in the scope that the utility model patent contains.
