A few days ago, company of Japanese city smooth industry is in exposition of product of 2008 international electron (AT International 2008) on, exhibited the adoption of this company newest research and development the new-style luminous intensity distribution of white LED is alterable type car headlamp (AFS) .
What traditional LED lamp uses is structure of diode of glow of onefold LED chip, and total luminous flux is lower, shed lightness to cannot achieve the use requirement of car headlamp, and fast degree not strong, service life is opposite shorter, need often changes, cannot satisfy the use on the car. Nevertheless, the ceaseless development as electronic technology and perfect, ao Di used auxiliary LED light on headlamp of car of preexistence of Motor Corporation rate.
The new-style headlamp of research and development of company of city smooth industry, broke through the technical corrupt practice of traditional LED lamp likewise, increased updated technique and function at the same time. The component that new-style headlamp odd sidelight secures by two rotates with package is formed, mix in fixed component rotate package all distributes stock lamp of LED of a group of white, these deploy the white LED at each component to all use 4 LED chip. Package respect, fixed component is measuring projector type, and rotate package can be used go forward one by one type motor undertakes gyral. Among them, rotate package uses relatively different new-style construction, undertake twice reflexing to coming from the light of white LED lamp, final illuminate to car ahead.
The advantage of headlamp of alterable type of LED of this kind of new-style white depends on, can go continuously according to car, turn, freeway travel, urban district drives wait for different position, and weather variation undertake changing pattern of luminous intensity distribution. For example, assemble the car of headlamp of alterable type of LED of this kind of white, turning the illuminate control that the point of view that change luminous intensity distribution can adopt when travel has bending ahead, and return when the travel on the freeway but will rotate the smooth axis of package adjusts up slightly, increase the output power of LED lamp, in order to raise car far can inspect a gender. Additional, when travel of car urban district, can rotate the left and right sides package changes one's political stand side severally square, side of satisfy the need undertakes illuminate, or in the illuminate when heavy rain the road shoulder of two side, can inspect a gender in order to raise what to protecting column reachs road side roadblock.
The xenon lamp of HID of total luminous flux of this LED headlamp can reach same level, shed lightness to achieve 12 thousand Lm, and efficiency of LED lamp glow achieved 100lm/W, power comsumption is 35W~40W, section report sex and wear want greatly the HID xenon lamp that excel uses extensively on the car at present. Current, city smooth industry already at this point LED headlamp technology and company of car of much home Japan undertake cooperative, in believing to will appear very quickly in the quantity to produce a model.
