Description
Technical field
The utility model is about a kind of lighting apparatus, especially about a kind of lighting apparatus that utilizes the mode of not having section to adjust light angle.
Background technology
The headlight that general vehicle is used mainly is to adopt the bulb with two tungsten filaments, perhaps uses two bulbs to be used as the switching of high beam and dipped headlights.The bulb of two tungsten filaments can't be reached the effect of high brightness and low power consumption, and uses the practice of two bulbs to use one group of lampshade more, makes cost effectively to reduce.
Fig. 1 and Fig. 2 show a kind of existing headlight of using magnetic valve to switch high beam and dipped headlights.As shown in Figure 1, existing headlight 100 comprises a pedestal 101, a fluorescent tube 102, a magnetic valve 103, a spring 104 and a speculum 105.Be formed with an open-work 106 on the pedestal 101, pass wherein for fluorescent tube 102.The light that fluorescent tube 102 sends is by speculum 105 reflection outputs.See through to adjust fluorescent tube 102 and inverse time mirror 105 relative position, promptly changeable high beam and dipped headlights.Magnetic valve 103 is adjusted the position of fluorescent tube 102 in two sections mode, relies on the relative position of adjusting fluorescent tube 102 and speculum 105, causes the effect of high beam and dipped headlights switching.Spring 104 provides fluorescent tube 102 elastic restoring force up, relies on not do the time spent at magnetic valve, and fluorescent tube 102 is pushed back original position.Suppose Figure 1 shows that the state of dipped headlights, magnetic valve 103 does not act on, and fluorescent tube 102 then Figure 2 shows that the high beam state relatively away from pedestal 101, and magnetic valve 103 overcomes the strength of spring 104 and fluorescent tube 102 is down attracted, and makes fluorescent tube 102 relatively near pedestal 101.
Fig. 3 shows the schematic diagram of the illumination zone of existing headlight.As shown in Figure 3, the main light spot of the dipped headlights pattern of headlight 100 is at P1, and the main light spot of high beam pattern is at P2.The user only can be adjusted at P1 or P2 with main luminous point, main luminous point can't be adjusted at P1 and P2 other zone in addition.When the speed of a motor vehicle when for example 40km/hr is following, using dipped headlights to throw light on gets final product, and the speed of a motor vehicle uses the scope that dipped headlights threw light on can't reach optimal illumination when not having vehicle in more than the 100km/hr and the place ahead one segment distance for example, and be preferred mode with the high beam illumination this moment then.
When the speed of a motor vehicle there is no vehicle in for example 70km/hr and the place ahead one segment distance, may be to be good to be situated between at high beam and dipped headlights.In addition, when vehicle travelled mountain road, then the user may be the light illumination mode that comes closely than dipped headlights to the lighting demand in headlight.Yet prior art but can't satisfy the demand.The general vehicle instrument provides multistage adjustable rearview mirror, adjusts for the different users, does not but provide multistage adjustable headlight, for the user because of adjusting in different driving situations.
In addition, when vehicle when advancing, use magnetic valve to do the control of far and near lamp, also can be bad and make magnetic valve effect bad (misoperation) along with road conditions.And in above-mentioned conventional example, when needs used high beam for a long time, magnetic valve must be energized always, and this measure then is the waste power supply.
Summary of the invention
