Description

LED double-curved-surface reflection bowl high beam and low beam lamp

Technical Field

The utility model relates to an automotive lighting system, concretely relates to LED hyperboloid reflection bowl far and near light.

Background

The high beam and the low beam of the automobile are the most important configurations of the front part thereof. The performance of the high beam and the low beam is an important index of the performance of the whole automobile, and is more and more concerned by consumers and designers. The headlight is the eyes of car, and the market has not only shined far away to the demand of headlight far and near light, shines bright, still has proposed higher requirement to novel structure, brand degree of distinguishing, the dynamic effect of cool dazzling. The common halogen light source realizes the far and near light function, and the defects of illumination uniformity, illumination distance and illumination brightness are basically abandoned by designers or only used for low vehicle distribution types. Under the demands of users on safety, performance and high identification degree, the LED lens and the LED reflection bowl-type high-low beam are more and more widely adopted.

At present, far and near light of an LED light source on the market is realized by an LED lens type or an LED reflection bowl type, but the following problems exist:

(1) distance light and near light are realized through the LED distance light and near light integrated lens: the LED high-beam and low-beam realization scheme is high in cost performance, but the size of the lens is large, the diameter of the round lens is more than 70mm, the requirements of various models of small-size headlamps cannot be met, and in the process of switching high beam and low beam, the electromagnetic valve has clickly noise;

(2) realize distance and near light through the split type lens of LED: high-level high-distance performance can be realized, but the requirements of various models of small-size headlamps cannot be realized when the diameter of the low-distance light lens is more than 70 mm;

(3) distance and near light are realized through an LED + reflection bowl type: the LED far and near light implementation scheme with very high cost performance has a more novel modeling compared with the traditional LED lens type; however, when the high beam is turned on, the high beam area is not turned on, which affects the overall lighting effect, and the reflecting bowl has a dimension of about 70mm in the Z direction and about 300mm in the Y direction, which cannot meet the requirements of various models of small-sized headlamps.
