Abstract
The invention discloses a directional projection lamp. The directional projection lamp comprises a radiator, a side plate, a panel, a glowing component and a reflecting shade, wherein the glowing component and the reflecting shade are arranged in the cavity defined by the radiator, the side plate and the panel; the glowing component is arranged in the bottom opening of the reflecting shade; a light outlet is formed in the panel; the bottom opening of the reflecting shade is a circular opening of which the size is matched with that of the glowing component; a top opening is a trapezoid opening diverging to the circular opening; the side wall of the reflecting shade is transited to the trapezoid opening from the circular opening; a light guide passage is formed between the trapezoid opening and the light outlet of the panel. The directional projection lamp can accurately control the light path of the light emitted by the glowing component; the light of the projection lamp is transmitted just from the light outlet during operation, and does not scatter in the circumferential direction basically, so the projection lamp can just illuminate to the front of the light outlet during operation; special projection effect can be played; the projection lamp can be applied to special occasions of exhibition halls and the like.
Description
Technical field
The present invention relates to a kind of lighting, be specially a kind of projecting lamp.
Background technology
Projecting lamp is a kind of widely used illuminating product.Traditional projecting lamp is all directly be installed on lamp housing by lamp holder, and the light that lamp holder sends directly is penetrated by light-emitting window, and these light are all unmanageable, and this projecting lamp can only meet general occasion and use.In part occasion, user needs projecting lamp to concentrate to project in specific region, and this requirement is that current projecting lamp is implacable.
Summary of the invention
In order to solve above technical problem, the invention provides a kind of directed projecting lamp, its projection illumination region can accurately control, and can meet the instructions for use of special occasions.
The technical scheme that the present invention adopts for technical solution problem is:
A kind of directed projecting lamp, comprise radiator, side plate, panel, luminescence component and reflection shield, radiator is fixed on the bottom side of side plate, panel is fixed on the top side of side plate, radiator is located at by described luminescence component and reflection shield, in the cavity that side plate and panel surround, wherein luminescence component is fixed on radiator, reflection shield is fixed on above luminescence component, luminescence component is positioned at the bottom side openings of reflection shield, described panel is provided with light-emitting window, the bottom side openings of described reflection shield is a circular port mated with luminescence component size, open top is the trapezoidal mouth departed from directly over circular port, the sidewall of reflection shield is transitioned into trapezoidal mouth from circular port, the guide lighting channel surrounded by vertical riser is provided with between trapezoidal mouth and the light-emitting window of panel, the size of light-emitting window is equal with the cross section of guide lighting channel.
As preferred embodiment, described guide lighting channel and light-emitting window are square structure.
As preferred embodiment, be also provided with the cylindrical cap that cross section is greater than described trapezoidal mouth between described reflection shield and panel, described guide lighting channel is wrapped in cylindrical cap.
The invention has the beneficial effects as follows: the present invention accurately controls the light path of luminescence component emitted light by reflection shield, guide lighting channel, light-emitting window etc., during work, the light of projecting lamp can only appear from light-emitting window, what the present invention adopted is the reflection shield of special shape, experiment proves that light can not scatter in peripheral direction substantially under the effect of this reflection shield, therefore only can throw light on towards the front of light-emitting window during shot-light work, thus reach special projection, the special occasions such as exhibition room can be met and use.
Accompanying drawing explanation
Be further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is decomposition chart of the present invention;
Fig. 3 is the overall structure figure of reflection shield.
Symbol description: 1-radiator, 2-side plate, 3-panel, 4-luminescence component, 5-reflection shield, 6-guide lighting channel, 7-cylindrical cap, 31-light-emitting window, 51-bottom side openings, 52-open top.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, projecting lamp of the present invention is primarily of compositions such as radiator 1, side plate 2, panel 3, luminescence component 4, reflection shield 5, guide lighting channels 6.Radiator 1, side plate 2 and panel 3 surround a cavity, wherein radiator 1 is fixed on the bottom side of side plate 2, and panel 3 is fixed on the top side of side plate, and the shape of this cavity in various embodiments can be different, as square, cylindricality etc., it is square structure in the present embodiment.Luminescence component 4 and reflection shield 5 are all arranged in above-mentioned cavity, and wherein luminescence component 4 is fixed on radiator 1, and the heat sent during work is outwards shed by radiator 1, and the light-emitting area of luminescence component 4 is towards panel 3 side.Reflection shield 5 is fixed on above luminescence component 4, and luminescence component 4 is positioned in the bottom side openings 51 of reflection shield 5, and reflection shield 5 extends to the bottom side of panel 3, and namely its open top 52 is near panel 3.
As shown in Figure 3, reflection shield 5 bottom side openings 51 of the present invention is a circular port mated with luminescence component 4 size, and open top 52 is for departing from the trapezoidal mouth directly over circular port, and the sidewall of reflection shield 5 is transitioned into trapezoidal mouth from circular port.The light that this reflection shield 5 makes luminescence component 4 send non-immediate is mapped to open top 52, but carry out light transmission by the mode of reflection, the light penetrated from open top 52 is soft, and experimentally prove, under the reflection shield effect of this shape, light can penetrate towards the front of open top 52 substantially, guarantees that projecting lamp can play the effect of directed projection.
Guide lighting channel 6 is located between trapezoidal mouth and the light-emitting window of panel, and this guide lighting channel 6 is surrounded by vertical riser.Shape due to this guide lighting channel 6 is mated with the light-emitting window 31 be located on panel 3, and the light therefore penetrated from reflection shield 5 only enters in this guide lighting channel and just can penetrate from light-emitting window 31.Therefore, this guide lighting channel 6 and light-emitting window 31 limit injection scope and the region shape of light.In various embodiments, the shape of this guide lighting channel 6 and light-emitting window 31 can be arranged as required, and the shape set by it determines the effect of directed projection.In the present embodiment, guide lighting channel 6 and light-emitting window 31 are all square structures.
As shown in Figure 1, be also provided with the cylindrical cap 7 that cross section is greater than trapezoidal mouth between reflection shield 5 and panel 3, guide lighting channel 6 is wrapped in cylindrical cap 7.Under the effect of this cylindrical cap 7, the light failing to enter guide lighting channel 6 can be tackled by cylindrical cap 7, effectively avoids light fixture to occur the phenomenon of printing opacity.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
