Abstract
The utility model belongs to the technical field of automobile light fittings, and particularly relates to a radiating structure of a light-emitting diode (LED) front fog lamp. The radiating structure of the LED front fog lamp is a reflection and refraction system consisting of an LED light source, a radiator, a lens, a reflecting mirror, a shell and heat-conducting glue, wherein the reflecting mirror has an optical reflecting surface formed through free curved surface design; the LED light source is positioned at a focal point, and uses a plurality of LED light-emitting components, so that the heating value of a single piece is small; and the radiator is arranged in the shell and connected with the LED light source through the heat conducting glue. When the LED light source is turned on, light rays are shot out through the reflecting mirror and the lens, and the service life of the LED light source is prolonged while the requirements on F3 type photometric characteristics in national standards GB4660 and ECER19 are met.
Description
Technical field
The utility model belongs to automotive lighting light fixture technical field, is specially a kind of LED front fog lamp-radiator structure.
Background technology
The front fog lamp of automobile of prolonged application adopts filament bulb as light source in the past, and when some bright light source, the temperature in the lamp chamber is higher, power consumption is big.And the LED light source is that light emitting diode is as a kind of cold light source security reliability height; Can accurately control light type and lighting angle; Photochromic soft, free from glare, not mercurous, sodium element etc. maybe health risk material, have anti-vibration, anti-weighing apparatus and advantage such as hit, but former for being applied on the automobile lamp high-brightness LED light; Though the caloric value of low power consuming LED device is wanted much less than based on halogen bulb; But the most of heat of the latter is to result from outside the lamp device, and LED produces heat and concentrates in the small silicon chip, and the rise sharply non-uniform Distribution that causes thermal stress and LED chip light emitting efficient and fluorescent material of LED chip temperature swashs the problem of penetrating decrease in efficiency etc.; When the LED light source was formed automobile-used white lumination system, the dissipation problem of its heat was more serious.Therefore how through high efficiency heat dissipation technology, become the key challenge that the design of LED car light faces.
Summary of the invention
The right deficiency that overcomes prior art, the utility model provide a kind of simple in structure, radiating efficiency is high, response speed is fast, the LED illuminating source automobile front fog lamp of energy-conservation, long service life.
The design of the utility model is following: LED front fog lamp-radiator structure; The reflected refraction system that it is made up of LED light source, radiator, lens, speculum, housing, heat-conducting glue, the optical reflection face that speculum is shaped by the free form surface design, the LED light source is positioned at along; Use a plurality of LED light-emitting components; Make the caloric value of single-piece little, housing is built-in with radiator, is connected with the LED light source through heat-conducting glue.
The utility model is when lighting the LED light source; Penetrate behind light process speculum and the lens, the luminous intensity distribution performance requirement of F3 class in satisfying standard GB 4660 and ECE R19 is in the LED light source igniting; The heat that heat-conducting glue is produced the LED light source fast reaches on the connected radiator equably; Make heat and housing inner air convection, increased substantially the junction temperature that heat transfer rate and area of dissipation are effectively controlled the LED light source, reduce car light chamber temperature inside; Make the LED lamp can normal and stable ground luminous, the service life of improving the LED light source.

The specific embodiment
Below in conjunction with specific embodiment and Figure of description the utility model is described further, specific embodiment described herein is only in order to explaining the utility model, and is not used in and limits the utility model ground.
Embodiment: LED front fog lamp-radiator structure; It is characterized in that the optical reflection face that speculum is shaped by the free form surface design by the reflected refraction system that LED light source, radiator, lens, speculum, housing, heat-conducting glue are formed, and the LED light source is positioned at along; Use a plurality of LED light-emitting components; Make the caloric value of single-piece little, housing is built-in with radiator, is connected with the LED light source through heat-conducting glue.
The utility model is when lighting the LED light source; Penetrate behind light process speculum and the lens, the luminous intensity distribution performance requirement of F3 class in satisfying standard GB 4660 and ECE R19 is in the LED light source igniting; The heat that heat-conducting glue is produced the LED light source fast reaches on the connected radiator equably; Make heat and housing inner air convection, increased substantially the junction temperature that heat transfer rate and area of dissipation are effectively controlled the LED light source, reduce car light lamp chamber temperature inside; Make the LED lamp can normal and stable ground luminous, the service life of improving the LED light source.
