Abstract
The utility model discloses a kind of polarisation Projecting Lamp, comprise lamp body, LED lamp bead, rod lens and LED drive power; Described lamp body is arranged on fixed support, and lamp body is equipped with cover, is provided with heat-radiating substrate and power source cavity in lamp body, and described heat-radiating substrate is fixing on a heat sink, and heat-radiating substrate is pasted with LED lamp bead, and LED lamp bead is outside equipped with rod lens; In described power source cavity, LED drive power is installed; The utility model by arrange outside LED lamp bead through design rod lens, according to polarisation refraction principle, make illuminated perpendicular uniform light distribute and range of exposures is extended to required scope, improve the utilization rate of light; Use combined integratedization luminous intensity distribution, assembly technology operation is more simple, and reliability improves greatly; More traditional Projecting Lamp colour rendering index is high, and under similarity condition, in same illumination range, the utility model dissipated power is low, and energy-efficient performance is superior; The utility model adopts LED solid state light emitter, radiationless, pollution-free, environmental protection more.
Description
Technical field
The utility model relates to a kind of light fixture, specifically a kind of polarisation Projecting Lamp.
Background technology
The LED projector lamp of prior art has following shortcoming: the first, and traditional Projecting Lamp power consumption is large, light fixture blanching; The second, traditional Projecting Lamp colour rendering index is low, can not show well image color authenticity; 3rd, existing LED projector lamp bright dipping is direct light, and flood lighting district utilization rate is low; 4th, existing LED projector lamp modular assembly packaging technology is complicated, adjustment angle is complicated; 5th, the existing LED projector lamp irradiation perpendicular uniformity is good not; For these reasons, need to make the Projecting Lamp of prior art to improve to adapt to user demand.
Utility model content
The purpose of this utility model is to provide a kind of polarisation Projecting Lamp, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of polarisation Projecting Lamp, comprises lamp body, LED lamp bead, rod lens, heat-radiating substrate, fin, power source cavity, LED drive power, cover and fixed support; Described lamp body is arranged on fixed support, and lamp body is equipped with cover, is provided with heat-radiating substrate and power source cavity in lamp body, described heat-radiating substrate is fixing on a heat sink, heat-radiating substrate is pasted with LED lamp bead, and LED lamp bead is outside equipped with rod lens, and rod lens is the integrated design; Described power source cavity is arranged on lamp body inner lower, is provided with LED drive power in power source cavity.
As further program of the utility model: described LED lamp bead is at least set to two groups.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, design ingenious, by arranging the rod lens through design outside LED lamp bead, according to polarisation refraction principle, make illuminated perpendicular uniform light distribute and range of exposures is extended to required scope, improve the utilization rate of light; Use combined integratedization luminous intensity distribution, assembly technology operation is more simple, and reliability improves greatly; More traditional Projecting Lamp colour rendering index is high, and under similarity condition, in same illumination range, the utility model dissipated power is low, and energy-efficient performance is superior; The utility model adopts LED solid state light emitter, radiationless, pollution-free, environmental protection more.

Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Refer to Fig. 1-4, a kind of polarisation Projecting Lamp, comprise lamp body 1, LED lamp bead 2, rod lens 3, heat-radiating substrate 4, fin 5, power source cavity 6, LED drive power 7, cover 8 and fixed support 9; Described lamp body 1 is arranged on fixed support 9, cover 8 lamp body 1 is equipped with, heat-radiating substrate 4 and power source cavity 6 is provided with in lamp body 1, described heat-radiating substrate 4 is fixed on fin 5, heat-radiating substrate 4 is pasted with many group LED lamp bead 2, LED lamp bead 2 is outside equipped with rod lens 3, and rod lens 3 is the integrated design; Described power source cavity 6 is arranged on lamp body 1 inner lower, is provided with LED drive power 7 in power source cavity 6.
Operation principle of the present utility model is: power input access rated operational voltage of the present utility model, excite LED lamp bead 2 luminous through LED drive power 7, again by rod lens 3 polarisation refraction principle, uniform light of the present utility model is radiated on plane of illumination 10, because institute's irradiated plane size differs, concrete light distribution angle determines according to required shadow surface size, namely foundation illumination and square distance are inversely, in conjunction with illumination (E), light fixture luminous flux (Φ), illuminated area (W*H) and designed light fixture light efficiency (η), draw best optical profile:
Light fixture general power (Σ P)=P1+P2+P3;
P1:P2:P3=1:（R12/R22）：（R12/R32）；
Φ=ΣP*η；
Average illumination E=Φ * N/ (W*H)=Σ P* η * N/ (W*H);
Wherein, P1, P2, P3 are the power of LED lamp bead 2, and in R1, R2, R3=the utility model, the light source of the 1st, 2,3 groups of LED lamp bead 2 is to the distance of plane of illumination 10; W=billboard width, H=billboard height, N=cloth lamp quantity, η=light fixture light efficiency.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, various change can also be made under the prerequisite not departing from this patent aim.
