Abstract

The invention discloses a novel light-emitting diode (LED) automobile side turning lamp. The novel LED automobile side turning lamp comprises a lamp housing body, a lens and a circuit board component and is characterized in that the circuit board component is arranged on the lamp housing body and comprises two LEDs; each LED is slantways fixed through a bracket, so that the optical axis direction of the LED and the X axis of an automobile body form a 30-degree included angle; refractive racks for adjusting a light path and frosted grains are arranged on the inner surface of the lens, so that rays emitted by the LED are uniformly distributed in a range of an included angle which is of 5 to 60 degrees and formed by the rear part of the automobile and the X axis of the automobile body; and the lamp housing body is made of acrylonitrile butadiene styrene (ABS). The novel LED automobile side turning lamp is simple in structure and easy to assemble, utilizes the characteristics of an LED cold light source and completely solves the problem that water spray exists in the automobile side turning lamp with narrow volume, and the lamp housing is made of the low temperature resistance ABS material, so that the cost of the whole lamp is reduced wholly.

Description

A kind of New LED Auto side steering light

Technical field

The present invention relates to a kind of automobile lamp field, especially a kind of New LED Auto side steering light.

Background technology

At present, traditional Auto side steering light, employing be that lamp bulb is as light source, because the volume of lamp is usually very little, the interior heat of lamp is very high during work, so Merlon (Polycarbonate) the PC material that the general employing of lens and lamp housing is heat-resisting, toughness is good.But, greatest problem or the defective of its existence are: when lighting a lamp through after a while, then turn off the light, the interior temperature of lamp this moment is higher, and the outer temperature of lamp is lower, because action of thermal difference causes in the lamp house, external pressure is poor, cold air and moisture thereof that lamp house is outer, will be from such as wire harness, place, the trickle slit such as sealing ring sucks in the lamp house, permanent set is at the lens inner surface, in lamp, form water smoke, in the situation that air humidity is larger, even can form many globule, meeting be thought to leak by certain customers and complain the 4S shop to require to change, more crucial is to have influence on the identification that the proceeds posterolateral vehicle driver turns to front vehicles, and then may produce traffic accidents.

Summary of the invention

The invention provides a kind ofly do not form mist, the New LED Auto side steering light of energy-conserving and environment-protective.

For achieving the above object, technical scheme of the present invention is:

A kind of New LED Auto side steering light comprises lamp housing body, lens and circuit board assemblies, it is characterized in that:

Described lamp housing assembly comprises lamp housing body and copper sheet inserts, and wherein, the copper sheet inserts is located at the bottom of lamp housing body, and the making material of lamp housing body adopts ABS;

Described circuit board assemblies is installed on the lamp housing body, includes 2 LED, and LED fixedly makes the optical axis direction of LED and vehicle body X-axis form 30 ° angle by riding;

Described lens inner surface is provided with refraction tooth bar and the frosted line of adjusting light path, and the light that LED is sent is evenly distributed in 5 ° ~ 60 ° the angular range zone of rear view of vehicle and the formation of vehicle body X-axis.

Be provided with one below the described lamp housing body for detection of the taper fabrication hole of the airtight situation of whole lamp.

Be provided with the sealing ring that fabrication hole is sealed below the described fabrication hole, sealing ring material adopts natural silicon rubber.

Described circuit board assemblies also includes one group of copper sheet docking adapter, and the copper sheet docking adapter inserts the copper sheet inserts, carries out the introducing of power supply by the copper sheet inserts.

The New LED Auto side steering light of above structure, simple in structure, easily assembling; Utilized the characteristic of LED cold light source, so that temperature can almost be consistent with the outer temperature of lamp house in the lamp house, do not form pressure reduction, thereby the problem that the lens inner surface of avoiding action of thermal difference to cause forms mist thoroughly solves the water smoke difficult problem of the narrow side steering indicating light installed existence of volume; And the led light source energy consumption is low, meets the requirement of the energy-conserving and environment-protective that country advocates; In addition, because the reduction of temperature in the lamp house can change the ABS material of selecting heatproof lower into, and then reduce on the whole cost on the making material of lamp housing.
