Background

The down lamp is a lighting lamp embedded in a ceiling and emitting light downward, and belongs to a directional lighting lamp. Down lamp on the market uses the luminous down lamp of side to give first place to, as shown in fig. 1, the main luminous core member of the luminous down lamp of side is optics three-piece, promptly: a diffusion plate 100, a light guide plate 200, and a reflective paper 300. The light guide plate is easily yellowed, and the whole light emitting effect is influenced. Secondly, the side luminous tube uses the annular soft lamp strip 400 as a luminous light source, and the side irradiation realizes the illumination function after being refracted and reflected by the optical three-piece set, so that the light transmission efficiency is low, and the requirement on the dimensional tolerance of the optical piece is high. The light emission value may fluctuate within a certain range due to the deviation of the physical dimensions.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a stable down lamp of luminous effect optimizes conventional optics three-piece suit, will incline luminous the luminous of changing into straight following formula, reduces the multiple reflection conduction process of light, realizes stabilizing luminous effect.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model discloses a down lamp that luminous effect is stable, including face ring sum optical assembly, optical assembly sets up in the face intra-annular. The optical assembly comprises an aluminum substrate and a diffusion piece. And the aluminum substrate is provided with a DC connecting line and a plurality of LED lamp beads. The aluminum base plate is fixed on the surface ring, and the diffusion piece is tightly pressed between the aluminum base plate and the surface ring.

Further, the diffusion piece is made of PC plastic.

Further, the diffusion sheet has a downward curved arc.

Further, the supporting pieces are distributed at equal intervals.

Further, the supporting sheet is in an isosceles trapezoid shape.

Furthermore, a gap exists between the outer wall of the supporting sheet and the inner wall of the surface ring, and a space is reserved when the supporting sheet is extruded and deformed by the aluminum substrate and is stretched outwards.

Furthermore, a plurality of threaded columns are arranged on the surface ring, a plurality of through holes matched with the threaded columns are formed in the aluminum substrate, and screws penetrate through the through holes to fix the aluminum substrate on the surface ring.

Further, spring clips for fixing are arranged on two sides of the face ring.

Further, a wire clamp used for fastening the DC connecting wire is further arranged above the aluminum base plate.

The utility model discloses an useful part is:

1. the utility model discloses cancel conventional optics three-piece (diffuser plate, light guide plate, reflection of light paper), trade the optics three-piece parts of diffusion light for more stable diffusion, the diffusion can adopt injection moulding, and the mechanical deviation of physics is less, and is comparatively stable, but also reduces manufacturing cost.

2. The utility model discloses change the luminous scheme of straight following formula into with the luminous scheme of side, the conduction process of light is the light source on the aluminium base board and directly from top to bottom spreads to the outside on penetrating the diffusion sheet, reduces the light loss of reflection diffusion in-process, realizes stabilizing luminous effect.

3. The utility model discloses a diffusion piece supporting part is the backing sheet of a plurality of equidistant and constitutes, has certain elastic deformation's function, and when aluminium base board was fixed in the face and encircles, the diffusion piece can carry out small elastic deformation and come the whole height of automatic adjustment, reduces the manufacturing requirement of diffusion piece.
