Technical field
The present invention relates to automobile lamp field, be specifically related to a kind of front fog lamp by LED array module and PMMA lens luminous intensity distribution.
Background technology
LED light source its have the life-span is long, light efficiency is high, radiationless advantage, LED the theoretical life-span more than 100,000 hours, luminous efficiency is up to 90%, and the energy consumption that identical light leads to is only 30% of Halogen lamp LED, there is the advantage of significant green, low-carbon (LC), worldwide, LED has obtained the extensive application obtained at lighting field.
Because the space requirement of generic halogen bulb to light fixture is larger, and modern lighting fixtures becomes elongated according to the moulding demand of car load, and elongated part adopts traditional halogen light source to be difficult to meet the requirement of luminous intensity distribution.Therefore the front fog lamp of LED light source luminous intensity distribution just creates.
Adopt the temperature in conventional halogen lamp bulb chamber very high, the material that our light fixture uses also must use resistant to elevated temperatures material, only has the heat dissipation problem solution fast and effectively of LED module, adopts ordinary lamp and lantern material also can reach heat resistant requirements, reduce costs.
Summary of the invention
For above-mentioned Problems existing, the invention provides a kind of front fog lamp by LED array module and PMMA lens luminous intensity distribution.
Technical solution of the present invention is: a kind of front fog lamp passing through LED array module and PMMA lens luminous intensity distribution, comprise lamp body, lens, upper decorative circle, lower decorative circle, LED reflection mirror, PMMA lens, pcb board assembly, aluminium alloy cooling stand, the side's of adjustment buckle, O RunddichtringO, adjusting rod and self-tapping screw, wherein descend decorative circle and PMMA lens, LED reflection mirror, aluminium alloy cooling stand and pcb board assembly to form light source assembly; Described light source assembly is fixed in lamp body, is fixed on lamp body by adjusting rod and O RunddichtringO.The present invention utilizes the special construction of convex lens, and the light degree of polymerization that LED is sent is higher, and the penetration capacity of light is stronger; And use the LED module of 5 1W just to reach the light distribution requirements of the GB4660 of front fog lamp, make the heat radiation of front fog lamp ratio be easier to solve, and the moulding of front fog lamp can be made to become more highly diverse, be not limited to conventional bulb class front fog lamp to the requirement in space; Have brightness high, outgoing light type graininess arranges, and uniform light is soft, the feature of long service life.
Further improvement of the present invention is: described pcb board assembly 7 comprises circuit controller and wire harness assembly.
Further improvement of the present invention is: described LED reflection mirror 5 is for vacuum aluminum-coated, and structure is semicircular light distribution surface and the side vertical edge for being in the light.
Further improvement of the present invention is: described front fog lamp is made up of the LED light source that 5 are welded on 1W on pcb board assembly.
Further improvement of the present invention is: speculum luminous intensity distribution region is the ellipsoid of 1/2nd.
The invention has the beneficial effects as follows: the present invention utilizes the image-forming principle of convex lens, the light that LED light source sends obtains the luminous intensity distribution light type of needs again after speculum refraction by PMMA set of lenses.LED array luminous intensity distribution can solve and substitute with the plurality of LEDs of lower-wattage the requirement that single high-power LED reaches luminous intensity distribution, reduces cost, and also can have larger flexibility in appearance and modeling; Cost is low, and not independent bulb is fixed, simple to operate.
