Abstract

The utility model relates to a car light, in particular to an antidazzle light of car. The utility model comprises a light cover body, a light source positioned in the light cover body and a reflection mirror. The focus of the lower part of the reflection mirror is closer to the front than the focus of the upper part of the reflection mirror. The light source is positioned between the two focuses, and the axial dimension of the light source is less than or equal to the distance between the two focuses. The focus on the lower part of the reflecting mirror dislocates forwardly, enabling the two focuses of the upper and the lower two parts of the reflection mirror be provided with a certain distance. A light emitting filament is arranged between the two focuses, and the cut-off line of the antidazzle light of car is guaranteed by the cut-off line of the upper and lower parts of the reflecting mirror. In this way, the shielded light irradiation by adopting conventional method is fully used, which guarantees the antidazzle effect, saves energy and improves the quality of light distribution and the qualified rate of products.

Description

The automotive anti-glare lamp
Technical field
The utility model relates to a kind of vehicle lamp, particularly a kind of automotive anti-glare lamp.
Background technology
The direct light that sends by bulb that existing car light in use exists, the light direct irradiation that the front upper place of automobile is sent by the bulb of car light.Therefore, when automobile during at night running, two cars are met will have dazzling light to enter the driver in the eyes, influences two side drivers' sight line, is easy to occur dangerous; When automobile travelled in the greasy weather, the light of direct projection in the automobile front upper place impinged upon on the mist pearl and forms diffuse reflection, makes the driver not see the road surface, and it is very difficult to travel.
Present known dipped beam non-dazzling light, be provided with difform filament shield below the general bulb that uses H4 or R2 classification, its dip filament, to form the basis of "cut-off"line, means realize luminous intensity distribution on speculum or lens routinely again, to reach related standards.Though another kind of form is not have filament shield on the bulb, and the sheet metal of similar filament shield is housed on the light fixture, works the effect of blocking, principle is basic identical.Like this, both lost illumination, and, made this class light fixture be in the critical condition of " up to standard " and " not up to standard " for a long time again owing to the first-class multiple reason of technology.
Summary of the invention
The utility model provides a kind of can effectively utilize illumination, and both energy savings promotes the automotive anti-glare lamp of luminous intensity distribution quality again.
The technical solution of the utility model is: comprise lampshade, be positioned at the light source and the reflective mirror of lampshade, described reflective mirror bottom focus is more forward than focal position, reflective mirror top, light source is between bifocal, and the axial dimension of light source is less than or equal to the bifocal distance.The utility model can adopt the known various light sources of car light that are used at present.
Employing misplaces the focus of the following part of speculum forward, makes the focus of two parts up and down of speculum leave certain distance, and light-emitting filament is placed between these 2, makes the "cut-off"line of anti-glare light be guaranteed by the cut-off rule of speculum top and the bottom.Like this, will use the be blocked illumination of part of conventional method all to utilize effectively, and both guarantee anti-dazzle effect, energy savings has again promoted the qualification rate of luminous intensity distribution quality and product.
Front portion at lampshade is equipped with lens.
The dead ahead that is positioned at light source can be equipped with the direct light anti-dazzling screen.The direct light that goes bulb to launch forward in order to retaining.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment;
Fig. 2 is that the utility model embodiment light projects the basic optical track figure on the screen.
Among the figure: 1. speculum, 2. speculum top part, the 3. following part of speculum, 4. direct light anti-dazzling screen, 5. lens, 6. lampshade, 7. light source, 8. focus one, and 9. focus two.
The specific embodiment
As shown in Figure 1, the anti-glare lamp of this automobile comprises lampshade 6, is positioned at the light source 7 and the reflective mirror 1 of lampshade 6, speculum 1 is made up of two parts: top part 2 and following part 3, upper and lower two-part focal position separately is respectively focus 1 and focus 29, distance between two focuses is H, and the dip filament 1 of bulb just is placed between these two focuses.The optical axis direction size of filament is less than or equal to two distance H between the focus, the optical track that the light of top part 2 reflection forms on the screen at 25 meters of distance light fixture is as shown in Figure 2 195 ° annular clear zone roughly, and the optical track that the light of following part 3 reflections forms on this screen is roughly in 165 ° of districts of former direction.Grid among Fig. 2 represents that partly the light of two parts mirror reflects has produced stack in this scope up and down.
After forming above-mentioned base light type as Fig. 2, add by the synthetic speculum of two parts up and down or by the conventional luminous intensity distribution means of lens 5, thereby easier reach related standard requirements, reach the purpose of lifting light quality.
Direct light anti-dazzling screen 4 is installed in by on the speculum that up and down two parts form, the direct light that goes bulb to launch forward in order to retaining.
Because this sharp light fixture has effectively utilized that a part of light that conventional method is blocked, thereby the utilization rate of light is greatly promoted keeping "cut-off"line clearly under the prerequisite.
