Abstract
The utility model discloses an automotive headlamp which comprises a transparent panel and a reflector. A CCFL tube is arranged in the reflector, a PET reflecting film, a light guide plate and a diffusion plate are arranged in the reflector in sequence. The PET reflecting film is attached to the bottom of the reflector, the transparent panel is arranged above the diffusion plate and connected with the reflector, and an optical pattern is arranged in the transparent panel. The automotive headlamp can overcome the shortcomings in the prior art, the PET reflecting film, the light guide plate and the diffusion plate are arranged, the optical pattern is arranged in the transparent panel, and the shape of the light guide plate is designed reasonably according to the lighting characteristics of a CCFL at the same time, so that lighting uniformity of the automotive headlamp is achieved, light-emitting efficiency is increased, and the automotive headlamp has high practical value.
Description
Technical field
The utility model relates to a kind of lighting device, especially a kind of car headlamp.
Background technology
Existing car light adopts LED lamp source mostly, substantially the not appearance for the matured product of vehicle light illumination by CCFL.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of car headlamp, can solve the deficiencies in the prior art, by PET reflective membrane, LGP and diffuser plate are set, optical patterns is set in transparent panel, simultaneously according to the shape of the characteristics of luminescence appropriate design LGP of CCFL, realize car headlamp and sent out uniformity of light, improved light extraction efficiency, there is very strong practical value.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of car headlamp, comprise transparent panel and reflector, in reflector, be provided with CCFL fluorescent tube, in described reflector, be disposed with PET reflective membrane, LGP, diffuser plate, PET reflective membrane pastes the bottom at described reflector, described transparent panel is arranged on diffuser plate top, is connected with described reflector; In described transparent panel, be provided with optical patterns; Described LGP is along the direction parallel with CCFL fluorescent tube length, and the thickness H1 at two ends reduces gradually to middle thickness H2, and described LGP is along the direction vertical with CCFL fluorescent tube length, and from the near-end of distance C CFL fluorescent tube to far-end, thickness H3 increases gradually.
As preferably, described CCFL fluorescent tube is serpentine configuration, and the distance between adjacent fluorescent tube is less than 2 times of fluorescent tube external diameter.
As preferably, the two ends of described CCFL fluorescent tube are fixed with vibration damping sheet, and the below of described CCFL fluorescent tube is provided with several bracing frames.
As preferably, the top of described reflector is provided with shading eaves, and shading eaves closes on the edge of described LGP.
The beneficial effect that adopts technique scheme to bring is: the light that in the utility model, CCFL fluorescent tube sends, through LGP, is eliminated interference, makes line source become area source, vision protection.According to the light intensity of CCFL fluorescent tube diverse location, LGP is designed to the different irregular cube of thickness, reduce the luminance difference of area source.Light forms diffusion during by diffuser plate and evenly diffusion, further improves uniformity.But the light directive property of diffusion is poor, finally refraction and the reflection to light by the optical patterns in transparent panel, the positive briliancy of raising area source.The PET reflective membrane that reflector bottom pastes can not penetrate part light reflection through LGP enters LGP, improves the luminous efficiency of overall light fixture.CCFL fluorescent tube is designed to snakelike, has improved space availability ratio, saved light fixture manufacturing cost, and improved light utilization rate.In CCFL lamp tube ends, vibration damping sheet is set, below arranges bracing frame, can protect CCFL fluorescent tube.Shading eaves on reflector reduces light and overflows, and improves the light extraction efficiency of light fixture.

Detailed description of the invention
With reference to Fig. 1-3, the utility model comprises transparent panel 1 and reflector 2, in reflector 2, be provided with CCFL fluorescent tube 3, in described reflector 2, be disposed with PET reflective membrane 4, LGP 5, diffuser plate 6, PET reflective membrane 4 pastes the bottom at described reflector 2, described transparent panel 1 is arranged on diffuser plate 6 tops, is connected with described reflector 2; In described transparent panel 1, be provided with optical patterns 7; Described LGP 5 is along the direction parallel with CCFL fluorescent tube 3 length, and the thickness H1 at two ends reduces gradually to middle thickness H2, and described LGP 5 is along the direction vertical with CCFL fluorescent tube 3 length, and from the near-end of distance C CFL fluorescent tube 3 to far-end, thickness H3 increases gradually.
It should be noted that described CCFL fluorescent tube 3 is serpentine configuration, the distance between adjacent fluorescent tube is less than 2 times of fluorescent tube external diameter.
Two ends that it should be noted that described CCFL fluorescent tube 3 are fixed with vibration damping sheet 8, and the below of described CCFL fluorescent tube 3 is provided with several bracing frames 9.
In addition, the top of described reflector 2 is provided with shading eaves 10, and shading eaves 10 closes on the edge of described LGP 5.
Operation principle of the present utility model is: the light that CCFL fluorescent tube 3 sends, through LGP 5, is eliminated interference, makes line source become area source, vision protection.According to the light intensity of CCFL fluorescent tube 3 diverse locations, LGP 5 is designed to the different irregular cube of thickness, reduce the luminance difference of area source.Light forms diffusion during by diffuser plate 6 and evenly diffusion, further improves uniformity.But the light directive property of diffusion is poor, finally refraction and the reflection to light by the optical patterns 7 in transparent panel 1, the positive briliancy of raising area source.The PET reflective membrane 4 that reflector 2 bottoms paste can not penetrate part light reflection through LGP 5 enters LGP 5, improves the luminous efficiency of overall light fixture.CCFL fluorescent tube 3 is designed to snakelike, has improved space availability ratio, saved light fixture manufacturing cost, and improved light utilization rate.At CCFL fluorescent tube 3 two ends, vibration damping sheet 8 is set, below arranges bracing frame 9, can protect CCFL fluorescent tube 3.Shading eaves 10 on reflector 2 reduces light and overflows, and improves the light extraction efficiency of light fixture.
More than show and described general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
