Description
Technical field
The present invention relates on a kind of ceiling that is arranged on self-propelled vehicle in order to illuminate indoor interior illuminator for automobile.
Background technology
As everyone knows, in the past as illuminating the indoor illumination equipment of self-propelled vehicle, adopt bulb as light source.This illumination equipment is arranged on the ceiling in the car, and except the bus attendant operating switch illuminated in the car, the car door opening state when the night boarding was also to illuminating in the car.Yet, under with the occasion of bulb, for obtaining enough light quantities, must use large-scale bulb, thereby produce the problem bigger in the car that reaches as light source.Therefore, though consider to use a plurality of miniature bulbs also can obtain the light quantity equal with large-scale bulb,, so not only consumption of current is big, and heat radiation is also big, and has the generation hot spot in range of exposures.
On the other hand, well-known, as other illumination equipment, adopted fluorescent lamp as light source (for example opening flat 10-129345 communique) with reference to the spy.Fluorescent lamp is compared the few and hot spot of consumption of current with bulb also few, yet fluorescent lamp is more elongated than bulb, big problem still can occur if wish to get with the same enough light quantities of bulb.And, because need be than relatively large driving circuit for lighting a lamp of driving fluorescent lamp, thus be difficult to the formation miniaturization, thus the ceiling that can produce in the car stretches out bigger problem.In addition, fluorescent lamp is because of the range of exposures non-directive, leaks to driver's seat and mirrors problem on the glass for vehicle window so can produce light.In addition, fluorescent lamp not only begins to the time of lighting a lamp longer from energising, and also bad to the rising of due light quantity from when beginning of lighting a lamp.Thus, when car door opening, also just can't utilize fluorescent lamp to light a lamp, because for bulb also must being set, thereby not only increase number of parts and packing engineering becomes many and cost is improved, but also produce the problem that maximizes with the open interlock of car door to taking one's seat.
For solving the above problems, the objective of the invention is to, provide a kind of light that can prevent to leak to operator's compartment and mirror vehicle window but also can the few enough light quantities of hot spot illuminate the rear portion seat, and consumption of current and dispel the heat less, can form miniaturization and can reduce the interior illuminator for automobile of manufacturing cost again.
Summary of the invention
For achieving the above object, the interior illuminator for automobile that is installed on the self-propelled vehicle indoor canopy of the present invention is characterized in that comprising: the cold-cathode tube with specified length; Drive the cold-cathode tube driving circuit of this cold-cathode tube; The operating switch of lighting a lamp, turning off the light of operation cold-cathode tube; When keeping described cold-cathode tube and operating switch, also receive the housing of adorning described cold-cathode tube driving circuit, this housing is positioned at the rear of driver's seat and is installed in the middle position of overall width direction, the range of exposures of described cold-cathode tube is set in the below of the glass for vehicle window lower edge at driver's seat rear.
According to the present invention, adopt cold-cathode tube as light source, because make the housing that keeps this cold-cathode tube be positioned at the rear of driver's seat and be installed in the middle position of overall width direction, light quantity that therefore can be enough is thrown light on to the rear portion seat.And, because utilize the directive property of the narrow light that cold-cathode tube has, range of exposures is set in the below of the glass for vehicle window lower edge at driver's seat rear, therefore not only leak to the light of driver's seat extremely less and also the reflection of light of mirroring on the glass for vehicle window at the rear portion seat also extremely few, thereby can keep well from outside the looking into the distance of vehicle window.
In addition, because not only power consumption and dispel the heat less of cold-cathode tube, and when can obtaining enough light quantities, can also form miniaturization, if therefore this cold-cathode tube is used as light source, can make illumination equipment form very small-sized (but special thickness thinning size).
