Description
Technical field
The utility model relates to a kind of lighting device, particularly relates to a kind of the installation and is located in the vehicle interior roof light tool, and utilize light-emitting diode to produce the lighting device of illuminating effect.
Background technology
As shown in Figure 1, be an existing vehicle interior roof light device 1, comprise a lamp socket 11, one and the lampshade 12, that fits together of lamp socket 11 be arranged on conducting strip 13 in the lamp socket 11, one and the bulb 15 that electrically connects of conducting strip 13, an and switch member 14, utilize switch member 14, the control electric current reaches bulb 15 through conducting strip 13, makes that bulb 15 is luminous.
Yet, because the illuminating ray brightness that at present existing bulb 15 itself is produced is generally not enough, can't reach effective room light purpose really, feel very difficult when the passenger carries out reaching materials and reads in the car.
As shown in Figure 2, for improving the general not enough disappearance of above-mentioned existing vehicle interior roof light device 1 illuminating ray brightness, relevant dealer further develops the interior daylight ceiling light device 2 of car as shown in Figure 2, it comprises one and is locked in the lampshade 22 that lamp socket 21 on the roof, is locked in lamp socket 21, and a fluorescent tube 23 that can exhale light.Utilize can the shed illuminating ray of higher brightness of fluorescent tube 23, can greatly promote room light brightness, yet, daylight ceiling light device 2 obviously is different from overall structure and circuit configuration and above-mentionedly assembles vehicle interior roof light device 1 fully in former in the car, quite loaded down with trivial details and consuming time when reequiping the configuration operation, even can cause negative effect to former car internal structure and Nei Guan.
As shown in Figure 3, therefore, relevant dealer is because the refitting engineer of the interior daylight ceiling light device of above-mentioned car is comparatively complicated, considering too not change under the prerequisite of former car internal structure and interior sight, mainly the bulb 15 of above-mentioned vehicle interior roof light device 1 is changed, cold cathode ceiling light luminaire 3 as shown in Figure 3 comprises a circuit board 34, two and is arranged on the CCFL 36 that joining piece 35, on the circuit board 34 can exhale the high brightness Cold light source, and one is arranged on the circuit board 34 and the control circuit device 37 that is electrically connected with two joining pieces 35 and CCFL 36.
In repacking, only need the bulb 15 of assembling vehicle interior roof light device 1 fully in the former car is pulled down, circuit board 34 with cold cathode ceiling light luminaire 3 is directly installed in the lamp socket 11 again, making two joining pieces 35 on the circuit board 34 touch two conducting strips 13 respectively gets final product, not only the dismounting combination is convenient, and can utilize the high brightness of the CCFL 36 that is arranged on the circuit board 34 to reach the effect that promotes room light brightness.
Yet, even if so, but because CCFL 36 when luminous, the comparatively huge transformer of volume that must possess on the control circuit device 37 can start smoothly, need leave bigger space between fluorescent tube 11 and the lampshade 12, therefore only be applicable to the car type that some is specific.
