Abstract
The invention relates to a three-color down lamp. The three-color down lamp comprises a heat sink, a light source, a middle ring, a lens and an outer ring, wherein the light source is connected with the heat sink through a pressure plate; the middle ring is in threaded connection with the heat sink; the lens is arranged between the middle ring and the outer ring; the light source has a circular structure; a circular warm-color light source is arranged in the light source; and an annular cool-color light source is arranged on the outside of the light source. The three-color down lamp is simple in structure and convenient to mount. The circular light source is adopted, the warm-color light source is arranged in the circular light source, the cool-color light source is arranged on the outside of the circular light source, and the problem of poor light spots is solved. When the warm-color light source is turned on, an inner ring is luminous, and the light spots are excellent; when the cool-color light source is turned on, the brightness of the cool-color light source is higher than that of the warm-color light source, and the area of dark space of the inner ring is reduced obviously; and when the warm-color light source and the cool-color light source are turned on simultaneously, the light spots tend to be consistent. Moreover, the outside and the inside of the lens are polished, and the effect of the light spots is improved further.
Description
Technical field
The present invention relates to technical field of lamps, refer to three look Down lamps especially.
Background technology
Three look Down lamps refer to and can send cool colour, warm colour and self-colored light fixture.The lamp source that three current look Down lamps adopt adopts the mode of four point-like light emitting sources, by cool colour and warm colour independent separately, distribute in diagonal angle.Although this arrangement mode is simply clear, after lighting, hot spot is obvious especially.When monochromatic luminescence, the paired linea angulata of hot spot, and also when colour mixture, hot spot is evident as four luminous point-like, there is dark space.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of three look Down lamps that can improve hot spot problem.
For solving the problem, the technical solution used in the present invention is: three look Down lamps, comprise radiator, light source, middle ring, lens and outer shroud, light source is connected with radiator by pressing plate, and middle ring is threaded mutually with radiator, and lens are arranged between middle ring and outer shroud, and the light-emitting area of light source is positioned at the inside of lens, described light source is circular configuration, and its inside is circular warm colour light source, and outside is the cool colour light source of annular.
Preferably, the diameter of the inside warm colour light source of described light source is 0.4 ~ 0.6 of whole source diameter.
Described lens are the horn-like structure of upper and lower difference opening, and its lighting angle is between 30 ~ 45 degree.
Preferably, the outside frosted of described lens.
Preferably, the frosted interior of described lens.
The invention has the beneficial effects as follows: three above-mentioned look Down lamps, its structure is simple, easy for installation, and the light of whole Down lamp is very soft, and hot spot effect is fine.It adopts circular light emitting source, and warm outer cold arrangement mode in adopting, the problem making hot spot bad improves a lot.During warm colour, inner ring is luminous, and hot spot is fine; During cool colour, because brightness itself is higher than warm colour, the dark space of inner ring is obviously reduced a lot; During colour mixture, hot spot reaches unanimity.In addition, owing to adding lens, make under Same Efficieney, the dimension of light source of this three looks Down lamp is less, and by the equal frosted process in the outside of lens and inside, improves the effect of hot spot further.

Detailed description of the invention
Below by specific embodiment, a kind of three look Down lamps of the present invention are described in further detail.
As shown in Figure 1 and Figure 2, three look Down lamps, comprise radiator 1, light source 2, middle ring 3, lens 4 and outer shroud 5, light source 2 is connected with radiator 1 by pressing plate 6, and middle ring 3 is threaded mutually with radiator 1, and lens 4 are arranged between middle ring 3 and outer shroud 5, and the light-emitting area of light source 2 is positioned at the inside of lens 4, described light source 2 is circular configuration, and its inside is circular warm colour light source 21, and outside is the cool colour light source 22 of annular.The diameter of the inside warm colour light source 21 of described light source 2 is 0.4 ~ 0.6 of whole light source 2 diameter.Described lens 4 are the horn-like structure of upper and lower difference opening, and its lighting angle, between 30 ~ 45 degree, after lighting angle refers to that light source 2 adds lens 4, irradiates light angle on the wall.
Preferably, the outside frosted of described lens 4.The frosted interior of described lens 4.
We have done two kinds of experiments, and cool colour warm colour is arranged according to concentrically ringed mode.Be according to the mode shown in Fig. 2, inside is circular warm colour light source 21, and outside is the cool colour light source 22 of annular; Another kind is inner is circular cool colour light source 22, and outside is the warm colour light source 21 of annular.In an experiment, we find, if when adopting cold outer warm arrangement in the second, when independent cool colour, because light source 2 is at center, effect is all right, but separately when warm colour, because inner ring cool colour is not luminous, time outer ring warm colour is lighted, from hot spot, obviously there is dark space in inner ring, equally, due to this situation that cool colour itself is brighter than warm colour, when colour mixture, from hot spot, inner ring becomes clear, and outer ring is partially dark, and effect is very bad.
But if when adopting the first this interior warm outer cold arrangement as shown in Figure 2, the bad problem of hot spot improves a lot.During warm colour, inner ring is luminous, hot spot OK; During cool colour, because brightness itself is higher than warm colour, the dark space of inner ring is obviously reduced a lot; During colour mixture, hot spot reaches unanimity, but center still exists a little dark space.
In addition, with fine sand mulberry paper in the equal frosted in the outside of lens 4 and inside, find that rear effect lighted by light fixture very good.
The above embodiments are the principle of illustrative the invention and effect thereof only, and the embodiment that part is used, but not for limiting the present invention; It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
