A kind of adjustable focal length LED car lamp
Technical field
A kind of LED car lamp is the utility model is related to, more particularly to a kind of adjustable focal length LED car lamp.
Background technology
LED car lamp is exactly the car light by the use of light emitting diode as light source, and traditional car light uses Halogen lamp LED more, luminous efficiency compared with
It is low, compare power consumption, illuminated environment temperature rise, service life it is short, LED light source principle of luminosity, energy-saving and environmental protection aspect on
All it is far superior to traditional lighting light fixture, and the perfection that the luminous one-way of LED is formd to car light luminous intensity distribution is supported, LED car lamp
Due to taking the illumination mode that solid luminescence diode is light source, the life-span depends primarily on solid LED light source and driving radiating part
Point, existing LED is using raffinal reflecting plate, light beam be most accurate, reflecting effect is optimal;The narrow angle of symmetric form, wide angle and non-
It is symmetrical to wait light distributing system, and car light has scale plate, and people can conveniently adjust irradiating angle according to scale, in addition, being
Maintenance is maintained easily, LED throws car light and more changed the bulb using behind open-type, and illumination and decoration effect is first-class, and LED projector lamp can reality
Existing gradual change, saltus step, color flash, random flicker, gradual change alternative and the dynamic effect such as chase, scan.
Under the technical conditions of existing LED car lamp, the convenience that is used in car light and functionally still exist very
More weak points, most of LED car lamp are all fixed focal length, it is impossible to carry out controllable type and focus, and it is more single to be applicable vehicle
One, manufacturer needs to configure different focal LED car lamp for different automobile types, is made troubles to manufacturer, on the other hand in face of more
It cannot be adjusted, be inconvenient during kind road conditions, vision, which can not debug, also easily causes security incident, influences safety of riding.
