Description
Technical field
The utility model relates to a kind of bus interior ceiling light, especially a kind of tunable light source bus interior ceiling light.
Background technology
The bus interior ceiling light is electronic devices and components very important on the passenger vehicle, and it has the effect of room light, and the power of its light quality comfortableness, security and light is particularly important for passenger behavior activity in the car.Consider in view of economic factor that traditionally the fluorescent lamp of bus interior ceiling light and shell thereof adopt general low-grade material usually, the weak and poor stability of its fluorescent lamp brightness, its casing plastic does not have anti-flammability, has potential safety hazard.Development along with modern society, the raising of quality of the life, the enhancing of awareness of safety, security, hommization and comfort level day by day become people and consider important factor, so a safe and reliable, bus interior ceiling light with human oriented design characteristics is the favor that is vulnerable to the consumer.
The utility model content
The purpose of this utility model provides a kind of tunable light source bus interior ceiling light, it is rational in infrastructure, adopt the high-performance new material, low power consuming, adopted the tunable light source technology, humanization designing has improved security and the comfort level of roof light greatly, can effectively substitute bus interior ceiling light traditional on the market.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of tunable light source bus interior ceiling light comprises roof light body and the power line that is connected with described roof light body.Described roof light body the place ahead is provided with the roof light drain pan, the rear is provided with the roof light lampshade, top, described roof light drain pan inside center position is provided with the roof light fluorescent tube, the bottom, center is provided with electric ballast, roof light drain pan lower left is provided with the power line hole, and described roof light fluorescent tube inside is provided with light sensor and light regulating circuit.
Further, described electric ballast inside is provided with holding circuit.
The beneficial effects of the utility model are: adopt high-quality LED illuminating lamp tube, be characterized in radiationless, without stroboscopic, energy-conservation comfortable, light is adjustable.Its electric ballast increases holding circuit, can prevent effectively that oscillistor from burning or produces high hotly, prolonged service life of voltage-stablizer and fluorescent tube.Shell adopts fire proofing, and components and parts are rationally distributed, are beneficial to dissipation of heat, high safety.Lampshade adopts high thoroughly material, high temperature resistant, anti-collision, difficult distortion, and elegant in appearance, ray refractive index is good.
