Abstract

The utility model discloses a light-emitting diode (LED) motorcycle headlight which comprises a shell body, a mask, an outer radiator, an LED light, an LED support and a pressing ring. The outer radiator is arranged at the bottom of the shell body, the LED support is arranged inside the shell body, and the LED light is arranged on the LED support. A reflector is further arranged inside the shell body, the mask is connected with an edge of the reflector in a buckled mode, and the mask is fixed on the shell body through the pressing ring. A heat pipe is arranged in the middle of the LED support, the upper portion of the heat pipe is arranged inside the shell body, and the lower portion of the heat pipe penetrates out from the bottom of the shell body and is connected with the outer radiator. The heat pipe is an efficient heat exchange element which is filled with working media in a sealed pipe shell and uses phase change of the media to adsorb heat and release the heat to carry out heat exchange. The LED light of the LED motorcycle headlight transmits heat sent out by means of the lighting of the LED light to the LED support, the LED support transmits the heat to the heat pipe, and then the heat pipe rapidly transmits the heat to the outer radiator outside the shell body, so that a good heat dissipation effect is achieved.

Description

A kind of LED motorcycle headlight

Technical field

The utility model belongs to the motorcycle lamp technical field, relates to specifically a kind of LED motorcycle headlight.

Background technology

At present, the light source great majority of motorcycle headlight are to adopt traditional osram lamp, because the power consumption of osram lamp is large, caloric value is large, low, the easy damage of available work efficiency, working life are short, causes easily traffic accident when motorcycle driving, often needs in time more change the bulb.In addition, traditional osram lamp shared space in installation process is larger, is unsuitable for the development trend of motorcycle headlight miniaturization.Some motorcycle headlight adopts LED to replace osram lamp in the prior art, the advantage of LED has: long service life, brightness are high, illuminating area is wide, power is low, power consumption is little etc., and raw material can be recycled, but LED lamp radiating effect of the prior art is not very desirable, there is the large defective of caloric value, how can provides the LED motorcycle headlight that a kind of radiating effect is desirable, effect is high to become the urgent demand of people.

The utility model content

The deficiency that the utility model exists in order to overcome prior art provides the LED motorcycle headlight that a kind of radiating effect is desirable, effect is high.

The utility model is achieved through the following technical solutions: a kind of LED motorcycle headlight, comprise housing, face shield, outer radiator, LED lamp, led support and trim ring, be provided with outer radiator in the bottom of housing, led support is arranged in the housing, the LED lamp is arranged on the led support, in housing, also be provided with speculum, the edge snapping of face shield and speculum, trim ring is fixed on face shield on the housing, middle part at led support is provided with heat pipe, the top of heat pipe is arranged in the housing, and the bottom of heat pipe is passed by the bottom of housing and is connected with outer radiator.

Described LED lamp is dipped beam LED.

The condenser mirror that described speculum is aluminized for the surface.

Described trim ring is the chromium plating trim ring.

Led support is provided with a fixed connection shaft at the middle part of housing.

Described outer radiator is the radiator with the grid fin.

The beneficial effects of the utility model are: heat pipe is a kind ofly to fill with working media and utilize the decalescence of medium and the high efficient heat exchanging element that heat exchange is carried out in heat release in the shell of sealing, it takes full advantage of the Rapid Thermal hereditary property of heat-conduction principle and refrigeration filling, be delivered to rapidly outside the thermal source through the heat of heat pipe with thermal objects, its capacity of heat transmission surpasses the capacity of heat transmission of any known metal.LED motorcycle headlight of the present utility model is provided with outer radiator in the bottom of housing, middle part at the led support with certain thermolysis is provided with heat pipe, the top of heat pipe is arranged in the housing, and the bottom of heat pipe is passed by the bottom of housing and is connected with outer radiator.Because such structure, the LED lamp is with its luminous heat transferred led support that gives out, led support is with the heat transferred heat pipe, heat pipe is delivered to heat on the outer outer radiator of housing more rapidly, thereby reach excellent radiating effect, the utility model is being kept under the advantageous prerequisite of original LED lamp institute, also have radiating effect ideal, advantage that effect is high, more prolonged the service life of LED lamp.
