Description

A kind of uniform projecting lamp of irradiation

Technical field

The utility model relates to technical fields of lighting fixtures, and in particular to a kind of projecting lamp of maintaining uniform illumination.

Background technique

The profile that projecting lamp is usually used in building decoration, illumination and heavy construction sketches the contours, and is also commonly used for auxiliary manufacture recently Lighting effects.Light that existing projecting lamp is cast out is simultaneously uneven, is upper slanting projection especially for projecting direction Often there is the upper and lower non-uniform situation that lower part light is concentrated, top light disperses in lamp.

Utility model content

In view of the deficiencies of the prior art, the utility model is intended to provide a kind of projecting lamp of maintaining uniform illumination, may be implemented to throw Project uniform light up and down.

To achieve the goals above, the utility model adopts the following technical solution:

A kind of uniform projecting lamp of irradiation, including lamp plate, lens and reflector；Light source and the lens on the lamp plate Lower end light inlet be correspondingly arranged, the upper end light-emitting window of the lens and the lower end light inlet of the reflector are correspondingly arranged；Institute The upper end light-emitting window of the upper end light-emitting window and the reflector of stating lens is tilted toward the opposite direction of projecting direction from the bottom up；Institute It states lens and reflector includes the upper side and lower side, and the upside of the lens and reflector is in the outer of projecting direction extension Convex arc shaped structure, downside is then in the planar structure extended to projecting direction.

Further, the upper end light-emitting window of the reflector is covered with pulverizer plate.

Further, the projecting lamp further includes having shell and glass plate, the lamp plate, lens, reflector and atomization Plate is set in the shell, and the glass plate, the periphery of the glass plate and the shell is arranged in the top of the pulverizer plate It is tightly connected.

Still further, the glass plate is armorplate glass.

The utility model has the beneficial effects that: the utility model specifically for upper oblique projection projecting lamp to lens and The structure of reflector improves, and may be implemented effectively uniformly to guide light emitted by the light source on lamp plate along projecting direction To reflector upper end light-emitting window and projected away according to the projecting direction of setting, the light projected is uniform up and down, light effect Fruit is good.

Detailed description of the invention

Fig. 1 is the projecting lamp schematic cross-section in the utility model embodiment；

Fig. 2 is the projecting lamp decomposition diagram in the utility model embodiment.

Specific embodiment

Below with reference to attached drawing, the utility model will be further described, it should be noted that the present embodiment is with this skill Premised on art scheme, the detailed implementation method and specific operation process are given, but the protection scope of the utility model is not It is limited to the present embodiment.

The present embodiment provides a kind of uniform projecting lamps of irradiation, as shown in Figs. 1-2, including lamp plate 1, lens 2 and reflector 3；The lower end light inlet of light source 4 and the lens 2 on the lamp plate 1 is correspondingly arranged, the upper end light-emitting window of the lens 2 and institute The lower end light inlet for stating reflector 3 is correspondingly arranged；The upper end light-emitting window of the lens 2 and the upper end light-emitting window of the reflector 3 Tilted from the bottom up toward the opposite direction of projecting direction；The lens 2 and reflector 3 include upside (lens 2 as shown in Figure 1 Upside 21 and reflector 3 upside 31) and downside (downside 22 of lens 2 as shown in Figure 1 and the downside 32 of reflector 3), and In the external convex arc shape structure extended to projecting direction, downside 22,32 is in for the upside 21,31 of the lens 2 and reflector 3 The planar structure extended to projecting direction.

In practical applications, the tilt angle of the upper end light-emitting window of the upper end light-emitting window and reflector 3 of the lens 2 Depending on crevice projection angle.

In above-mentioned projecting lamp, by the way that the upper end light-emitting window of the upper end light-emitting window of the lens and the reflector is arranged At from the bottom up toward projecting direction opposite direction tilt, and will be arranged on the upside of lens and reflector in projecting direction extend External convex arc shape structure, downside is arranged in the planar structure that extends to projecting direction, can be effectively by the light source institute on lamp plate The light of injection is uniformly guided to the upper end light-emitting window of reflector along projecting direction and is projected away according to the projecting direction of setting, The light projected is uniform up and down, and lighting effects are good.

Further, the upper end light-emitting window of the reflector 3 is covered with pulverizer plate 5.The pulverizer plate can to project Light out is softer.

Further, the projecting lamp further includes having shell 7 and glass plate 6, the lamp plate 1, lens 2,3 and of reflector Pulverizer plate 5 is set in the shell 7, and the top of the pulverizer plate 5 is arranged the glass plate 6, the periphery of the glass plate 6 and The shell 7 is tightly connected.The glass plate is for playing protective action to the lamp plate of lower section, lens, reflector and pulverizer plate.

Still further, the glass plate 6 is armorplate glass.

For those skilled in the art, it can be provided various corresponding according to above technical solution and design Change and modification, and all these change and modification, should be construed as being included in the utility model claims protection scope it It is interior.
