Abstract

The utility model relates to an LED automobile daytime driving lamp, which is provided with a circuit board and LED lamp beads arranged on the circuit board; and converging mirrors are arranged above the LED lamp beads, and are solid conical bodies provided with light collecting holes at bottoms and diffusing surfaces at tops. The LED lamp beads are arranged at the bottoms of the converging mirrors, and light rays emitted by the LED are collected by the light collecting holes, so that the light ray direction is changed, the light ray loss is reduced, the focused light is evenly diffused and sent out through divergent mirrors, and the daytime travelling lamp standard is met; the structure is small and simple; the lighting effect is high; the converging mirrors can be arranged and set according to actual requirement; and the applicability is stronger.

Description

LED automobile daytime running lamps

Technical field

The utility model relates to a kind of auto lamp, particularly a kind of LED automobile daytime running lamps.

Background technology

High-brightness LED has numerous advantages such as energy-saving and environmental protection, life-span are long, have a extensive future, so countries in the world has all been dropped into lot of manpower and material resources and carried out correlative study and industrialization.In recent years, along with the continuous breakthrough of great power LED technology, application constantly enlarged, entering part dedicated illumination field in a large number, and automotive lighting is one of them main application fields, in 2003, is used for automobile with regard to 15% high-brightness LED is arranged.Yet high-brightness LED is mainly used in automobile tail light and room light at present, generally is not used for the automobile daytime running lamps, and daytime running lamps are the light fixtures that are identified more easily when instigating vehicle to go by day; Be contained in body forward structure; That is to say that this light fixture is not an illuminating lamp, is not in order to make the driver can see the road surface clearly, but in order to let other people discern; It is the category that belongs to signal lamp; Because the daytime running lamps optical design is complicated, the traditional design method light efficiency is lower, causes the LED daytime running lamps to be difficult to satisfy the requirement of standard.

The utility model content

The purpose of the utility model provides a kind of above-mentioned shortcoming that overcomes, and is simple in structure, can satisfy the LED automobile daytime running lamps of standard.

The technical scheme that realizes the utility model purpose is: a kind of LED automobile daytime running lamps have circuit board and are arranged on the LED lamp pearl on the circuit board; Said LED lamp pearl top is provided with condenser, and condenser is the solid-cone body, and the bottom is provided with the light harvesting hole, and the top is provided with the face of dispersing.

The condenser of above-mentioned LED automobile daytime running lamps is the integral piece that polycarbonate or polymetylmethacrylate or polypropylene PP or the fine ABS of propylene or polyvinylchloride or optical glass are accomplished through injection moulding or Precision Machining manufacturing.

The condenser of above-mentioned LED automobile daytime running lamps has a plurality of, evenly distributed, and the LED lamp pearl quantity on the circuit board is identical with condenser, and the position is corresponding one by one.

The face of dispersing of above-mentioned LED automobile daytime running lamps is the decorative pattern face.

The face of dispersing of above-mentioned LED automobile daytime running lamps is formed for evenly distributed continuously circular arc.

The utlity model has positive effect: LED lamp pearl places the bottom of condenser, and the light that LED sends is collected by the light harvesting hole, thereby changes radiation direction; Reduce the loss of light, make the light of gathering evenly spread ejaculation through divergent mirror again, satisfy the daytime running lamps standard; Structure is small and exquisite simple; Light efficiency is high, and condenser can be arranged setting according to actual needs, and applicability is stronger.

Description of drawings

For the content that makes the utility model is expressly understood more easily,, the utility model is done further detailed explanation, wherein below according to specific embodiment and combine accompanying drawing

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model condenser cutaway view;

Fig. 3 is the partial sectional view of the utility model condenser.

The specific embodiment

See Fig. 1 to Fig. 3; The utlity model has circuit board 1 and be arranged on one group of evenly distributed LED lamp pearl 2 on the circuit board 1; Each LED lamp pearl 2 corresponding position is provided with a condenser 3, the solid-cone body that condenser 3 is accomplished through the Precision Machining manufacturing for optical glass, and the bottom is provided with light harvesting hole 31; The top is provided with the face of dispersing 32, disperses face 32 and forms for evenly distributed continuously arc surface.

Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
