Description
Technical field:
This utility model belongs to lighting field, and particularly to a kind of wide-angle Projecting Lamp, especially three reflective surfaces are all pacified
Projecting Lamp equipped with LED light source.
Background technology:
Application number 201410212923.3, open a kind of LED projector lamp, including shell, mounting bracket, LED light source structure,
Driving means, light transmission piece, shell medial surface is made up of the first inclined plane, light source installed surface, two the second inclined planes, and first tilts
Angle between face and light source installed surface is set to 100 degree to 140 degree.LED light source structure includes being located on light source installed surface
Circuit board, the LED lamp bead being located on circuit board.First inclined plane, light source installed surface, the second inclined plane of both sides are disposed as instead
Bright finish and all towards tilted thus formed and there is the reflecting surface structure of optically focused effect, when the LED lamp bead on light source installed surface is luminous
Time, the light being irradiated in the first inclined plane, the second inclined plane by reflection after all can be towards center position toward external exposure, optically focused
Effective.From luminous and luminous reflectance angle analysis, it is relatively strong still to there is longitudinal axis light in this Projecting Lamp, and the defect that both sides are weak, this
Class Projecting Lamp is theoretically simulated Metal halogen lamp, high light diffusing and wide-angle and is irradiated and design.How to be truly realized wide-angle high
Diffusible Projecting Lamp, becomes the object of this utility model research.
Summary of the invention:
The purpose of this utility model is that three reflective planes designed in a kind of four reflective planes are provided with LED light source,
Make direct projection superposition reflective, go out the wide-angle Projecting Lamp that light is more uniformly distributed.
Technical solutions of the utility model are achieved in that a kind of wide-angle Projecting Lamp, including housing, reflection shield, printing opacity
Sheet and power supply driver and LED light source；Described reflection shield has four reflective planes, including the little trapezoidal faces on axis,
Big trapezoidal faces and monosymmetric triangular facet, be wherein little trapezoidal faces near lamp socket one end, and far-end is big trapezoidal faces, at this little ladder
Shape face is provided with main LED light source；It is characterized in that: on two triangular facets of reflection shield, be respectively arranged with secondary LED light source, described secondary LED
Light source power is less than the power of main LED light source.
Described two triangular facet angles are between 90-120 degree, and big trapezoidal faces and little trapezoidal faces angle are between 110-130 degree；
Main LED light source power is more than secondary LED light source power twice.
The large-power LED light bead that described main LED light source and secondary LED light source refer to, or the combination die of low-power LED lamp bead
Block.
This utility model utilizes the structure of tradition four sides reflection shield, is respectively mounted power on monosymmetric triangular facet
Less than the secondary LED light source of main LED light source, both realized the uniformity of both sides light splitting, solved again high power single lamp bead or Assembled lamp
Pearl module heating is concentrated, and easily the defect of diffusion, kills two birds with one stone, and illuminating area is bigger evenly.
Accompanying drawing illustrates:
Below in conjunction with concrete legend, this utility model is described further:
Fig. 1 Projecting Lamp schematic perspective view
Fig. 2 Projecting Lamp horizontal section schematic diagram
Fig. 3 Projecting Lamp longitudinal profile schematic diagram
Wherein
The 1 big trapezoidal faces of the little trapezoidal faces of housing 2 reflection shield 21 22
The secondary LED light source of the 23 main LED light sources 42 of triangular facet 3 power supply driver 41
A two triangular facet included angle B large and small trapezoidal faces angle
Detailed description of the invention:
With reference to Fig. 1, Fig. 2 and Fig. 3, wide-angle Projecting Lamp, including housing 1, reflection shield 2, light transmission piece and power supply driver
3 and LED light source；LED light source includes main LED light source 41 and secondary LED light source 42, owing to being not related to not shown in light transmission piece figure；
Described reflection shield 2 has four reflective planes, including the little trapezoidal faces 21 on axis, big trapezoidal faces 22 and monosymmetric three
Edged surface 23, is little trapezoidal faces 21 near lamp socket one end, and far-end is big trapezoidal faces 22, is provided with main LED light in little trapezoidal faces 21
Source 41, and on two triangular facets 23, it is respectively arranged with secondary LED light source 42, secondary LED light source 42 power is less than the merit of main LED light source 41
Rate, general main LED light source 41 power is more than secondary LED light source 42 power twice so that left and right sides light intensity and axis side
To quite.And main LED light source 41 and secondary LED light source 42 can be large-power LED light beads, it is also possible to be low-power LED lamp bead
Composite module.Such as the Projecting Lamp of a 50W, main LED light source may be designed to 30W, and two secondary LED light sources are respectively 10W, not only light
There is configuration evenly, and the heat of 50W is separated into three regions, alleviates hot-spot, significantly slow down light decay and Projecting Lamp
Service life.
Described two triangular facet 23 included angle A, between 90-120 degree, are adapted most preferably 100 degree；Big trapezoidal faces 22 and little ladder
Shape face 21 included angle B between 110-130 degree, most preferably 120 degree；The optimum of these angles, with Projecting Lamp irradiated area and
Good irradiation distance is relevant, and different occasions are varied from.
