Embodiment
The utility model provides a kind of multifunctional lift cab flat lamp, to make the purpose of this utility model, technical scheme
And effect is clearer, clear and definite, the utility model is further described below.It is it should be appreciated that described herein specific
Embodiment only to explain the utility model, is not used to limit the utility model.
Referring to Fig. 1, a kind of multifunctional lift cab flat lamp, wherein, including light guide plate 23, front plane frame 22, back shroud 26
And light source assembly 21, front plane frame 22 are fixed on the top of light guide plate 23, back shroud 26 is fixed on the bottom of light guide plate 23, light source assembly
21 are arranged at the end of light guide plate 23, and light source assembly 21 also includes emergency light and normal lamp, and normal lamp is by normal lamp control circuit
27 connection controls, emergency light connect control by emergent lamp control circuit 28, meet an urgent need lamp control circuit 28 and normal lamp control circuit
27 is in parallel, and the light that light source assembly 21 is sent sheds after light guide plate 23 reflects and reflects.Light is distributed during to make emergency lighting
Uniformly and emergency light is frequently switched, and emergency light is evenly distributed in light source assembly 21, and in parallel with normal lamp, by power supply group
The co- controlling of part 21, during general lighting, normal lamp and emergency light work simultaneously；During emergency lighting, common circuit for lamp disconnects, and meets an urgent need
Lamp normal work, now the illuminance of ground of emergency light should be not less than 50 luxs.
In practical application, lamp source component 21 is LED.Traditional incandescent lamp, fluorescent lamp and Halogen lamp LED etc. are replaced with into LED
Lamp, make it have the absolute sexual clorminance that power consumption is small, response is fast, light efficiency is high, service life is grown.
In practical application, diffuser plate 24 is provided between light guide plate 23 and front plane frame 22, the diffuser plate 24 of setting, which combines, leads
Tabula rasa 23 acts on, and the light that light source assembly 21 is sent more is homogenized, and optimizes illuminating effect.
Further, reflecting plate 25 is provided between light guide plate 23 and back shroud 26, the reflecting plate 25 of setting combines leaded light
