Description

The optical lens of car light

Technical field

The utility model relates to a kind of optical lens of car light, and espespecially one kind can increase illumination region and light extensively Type, and brightness of illumination effect is improved, so that the optical lens of the car light of traffic safety can be increased.

Background technology

General vehicle can install the car light with difference in functionality in headstock in design, and the light shape and optical track of every kind of car light are all The regulation of regulation must be met, and the light shape of the dipped headlight of general vehicle and fog lamp is all horizontal ellipse, and it is located at a water The lower section of zero diopter axle, although the car light of such a smooth shape can reach the purpose closely illuminated, because light all concentrates on water The lower section of zero diopter axle, therefore, the region above the horizontal optical axis is more dim, and driver is not easy to recognize in night running The article of higher position, such as traffic sign etc., usually require to set up the structure of light filling so planting existing car light.

Recently, in order to improve traffic safety, designed for the illumination light shape of automobile lamp, require to improve pair of illumination gradually Degree of ratio；Traditional type head lamp is gradually projected formula car light and eliminated because being difficult to meet current international norm with requiring, and projection-type car Lamp optical system has lot of advantages, such as：

1. can have relatively low head lamp height, therefore it can be designed using this feature and can adjust answering for various different road conditions Combined lamps, can be in detour, cross road road lighting different from being improved during highway driving, to improve travel safety.

In the presence of 2. projection-type car light coordinates anti-dazzling screen, "cut-off"line more clear than traditional type head lamp can be produced, Driver's eyes of opposite car can be so allowed to feel more comfortable.

3. using transparent lamp case as protection rather than for spreading or deviation light, therefore it can use there is larger inclination The lamp housing at angle so that headstock can be designed to more smooth and rich change with vehicle light shape.

And the optical system of general projection-type car light, as TaiWan, China patent announcement the M451276th " it is adjustable it is far and near Vehicle lamp structure ", TaiWan, China patent announcement No. M470774 " head lamp optical texture ", TaiWan, China patent announcement I 521164 Number " vehicle with throw lamp construct " and TaiWan, China patent announcement the M481848th " lamp for automobile ", it is generally by speculum Face, lamp source, anti-dazzling screen and lens are formed；Using mirror surface by the light-ray condensing that lamp source is sent to a focus point, then move Dynamic projection lens makes lens focus be overlapped with the focus point, and is divided source by an anti-dazzling screen blocking part of given shape, to throw Project the demand light type with "cut-off"line (Cut-off Line).

And actual embodiment uses upper discovery, general light utilizes the curved surface of lens by injecting lens after focusing mirror Reflect illuminating ray, as shown in figure 9, using area of light figure represent irradiate come light range, in "cut-off"line down, Its central part has bright illumination region, is expressed as clear zone (A), and the dark space (B) of light source deficiency is more formed toward both sides, makes The scope that can be irradiated into its light type has limited, and causes it to still suffer from improved space in overall construction design.

Then, designer spy adhere to again the relevant industries for many years it is abundant design and develop and actual fabrication experience, pin once again Improvement is studied actual use, and spy provides a kind of optical lens of car light, has more preferably practical value to reach Purpose.
