Description

High usage LED signal lamp

Technical field

The utility model is related to automobile signal light technical field more particularly to a kind of high usage LED signal lamps.

Background technology

LED light source is widely used in automobile signal light, but compared to traditional bulb source, uses The signal lamp function of LED light source may in uniformity advantage, but be then not so good as when needing to illuminate larger light-emitting zone Light bulb, main or cost of tracing it to its cause and single led luminous flux also with caused by traditional light bulb gap, then The raising tried one's best in optical design is to the utilization rate of LED light source, it is possible to not increase LED quantity（Power）On the premise of accomplish Can compare the illumination region of light bulb, while have good uniformity again, and meet the signal lamp function of laws and regulations requirement, because This, solves the problems, such as that this one kind is particularly important.

Utility model content

In view of the deficiencies of the prior art, the utility model provides a kind of high usage LED signal lamp, utilizes multiple reflections Mirror is worked in coordination for LED light emitting angles, the capacity usage ratio to LED light source is significantly improved, so as to use Small number of LED realizes the uniform irradiation effect of larger area.

To solve the above-mentioned problems, the utility model provides a kind of high usage LED signal lamp, includes left side parabolic Line reflection mirror, right side parabolic reflector, hyperbolic reflector, left side ellipsoidal reflector, right side ellipsoidal reflector and first LED and the 2nd LED, the left side parabolic reflector, left side ellipsoidal reflector and right side parabolic reflector, right side ellipsoid are anti- It penetrates that mirror is symmetrical, hyperbolic is connected among the bottom of the left side parabolic reflector and the right side parabolic reflector The bottom of line reflection mirror, the left side ellipsoidal reflector and right side ellipsoidal reflector is respectively arranged with the first LED and the 2nd LED.

Further improvement lies in that：First LED is located in the interior focus of left side ellipsoidal reflector, the first LED's Light emission direction is Y positive directions, and the half energy of the first LED will be converged in the outer focus of ellipsoid by left side ellipsoidal reflector, The outer focus of left side ellipsoidal reflector overlaps again with the outer focus of hyperboloidal mirror simultaneously, by the light finally by hyperbolic Face speculum is reflected, these light are equivalent to the interior focus outgoing from hyperboloidal mirror, while the other half energy of the first LED Amount is then directly got on the parabolic reflector of left side, while the focus of left side parabolic reflector and left side ellipsoidal reflector is interior Focus overlaps, i.e., is overlapped with the first LED, what this some light can be parallel with X-direction is reflected.

Further improvement lies in that：System using the 2nd LED as light source is mirrored into the first LED, and light emission direction is negative Y side To the position of the 2nd LED is overlapped with the focus of the interior focus of right side ellipsoidal reflector and right side parabolic reflector, while right The outer focus of side ellipsoidal reflector is overlapped with the outer focus of hyperboloidal mirror.

The beneficial effects of the utility model are：The utility model is using multiple speculums for the mutual of LED light emitting angles Cooperation, significantly improves the capacity usage ratio to LED light source, so as to use small number of LED larger to realize The uniform irradiation effect of area, and the processing and manufacturing cost of system is reduced, and can also shorten convenient for modularized design Design cycle.

Specific embodiment

In order to deepen the understanding to the utility model, the utility model is further described below in conjunction with embodiment, The present embodiment is only used for explaining the utility model, does not form the restriction to scope of protection of the utility model.

As shown in Figure 1,2,3, 4, a kind of high usage LED signal lamp is present embodiments provided, includes left side parabola Speculum 1, right side parabolic reflector 2, hyperbolic reflector 3, left side ellipsoidal reflector 4, right side ellipsoidal reflector 5 and One LED6 and the 2nd LED7, the left side parabolic reflector 1, left side ellipsoidal reflector 2 and right side parabolic reflector 4, the right side Side ellipsoidal reflector 5 is symmetrical, the bottom of the left side parabolic reflector 1 and the right side parabolic reflector 2 it Between be connected with hyperbolic reflector 3, the bottom of the left side ellipsoidal reflector 4 and right side ellipsoidal reflector 5 is respectively arranged with One LED6 and the 2nd LED7.First LED6 is located in the interior focus of left side ellipsoidal reflector 4, and the first LED6's shines Direction is Y positive directions, and the half energy of the first LED6 will be converged to by left side ellipsoidal reflector 4 in the outer focus of ellipsoid, together When left side ellipsoidal reflector 4 outer focus again overlapped with the outer focus of hyperboloidal mirror 3, by the light finally by hyperbolic Face speculum is reflected, and according to bi-curved characteristic, these light are equivalent to the interior focus outgoing from hyperboloidal mirror, simultaneously The other half energy of first LED6 is then directly got on the parabolic reflector 1 of left side, while the focus of left side parabolic reflector 1 It overlaps, i.e., is overlapped with the first LED with the interior focus of left side ellipsoidal reflector 4, the characteristic of parabolic reflector, this some light It parallel with X-direction can be reflected.System using the 2nd LED7 as light source is mirrored into the first LED6, and light emission direction is negative Y-direction, the position of the 2nd LED7 are overlapped with the focus of the interior focus of right side ellipsoidal reflector 5 and right side parabolic reflector 2, The right side outer focus of ellipsoidal reflector 5 is overlapped with the outer focus of hyperboloidal mirror 3 simultaneously.

Light by parabolic mirror reflection according to embodiment 1 is concentrated mainly in small angle range, is passed through The light of hyperboloidal mirror reflection, which is concentrated mainly on, to be beaten in angular range, then can be according to the method for required design function The functional equation that rule correct speculum either adds specific optical patterns or surface treatment on the reflecting surface（Polishing, addition Scatter dermatoglyph etc.）, light is reflected into the region of specific laws and regulations requirement, so as to which the function of ensureing designed disclosure satisfy that accordingly Laws and regulations requirement.

The utility model working in coordination for LED light emitting angles using multiple speculums, significantly improves to LED light The capacity usage ratio in source so as to realize the uniform irradiation effect of larger area using small number of LED, and drops The low processing and manufacturing cost of system, and can also shorten the design cycle convenient for modularized design.
