Abstract
The utility model discloses a lamp bulb for operation shadowless lamps. The utility model is characterized in that the surface of the lamp bulb is provided with a composite film; the bottommost layer of the composite film is a silicon dioxide layers; the surface of the silicon dioxide layer is plated with a titanium dioxide layer. The lamp bulb can keep original luminous flux of more than 95 percents; the spectral characteristics are changed after plated with the film; the color temperature is controlled in 4500K positive and negative 200K. the film layer can resist high temperature to more than 500 DEG C.
Description
Technical field:
The utility model relates to the lighting for medical use apparatus technology, a kind of specifically being used for
The bulb of operation shadowless lamp, the particularly coating structure of its tube face.
Background technology:
The bulb of operation shadowless lamp use at present, its colour temperature is generally about 3200K, in order to reduce tissue, the blood color (the sunlight colour temperature is generally at 4000K-5000K) under sunlight, therefore operation needs to add optical filtering equipment in use with shadowless lamp, it is carried out colour temperature correct, this filter is influenced greatly by glass material, and the colour temperature deviation is big, consistency is bad, has also increased the equipment cost expenditure of hospital simultaneously.
Summary of the invention:
The purpose of this utility model is to provide a kind of bulb that is used for operation shadowless lamp, it has plated the composite membrane of silicon dioxide and titanium dioxide with the low pressure halogen tube face in operation, colour temperature 4500K ± 200K can be controlled at through behind the plated film, and former luminous flux more than 95% can be kept.
To achieve these goals, technical scheme of the present invention is: a kind of bulb that is used for operation shadowless lamp, and it mainly comprises bulb, it is characterized in that: described tube face is provided with composite membrane, the bottom of composite membrane is a silicon dioxide layer, and the silicon dioxide laminar surface is coated with titanium dioxide layer.
The utility model discloses a kind of bulb that is used for operation shadowless lamp, its low pressure halogen tube face has plated the composite membrane of multilayer silicon dioxide and titanium dioxide, it can keep the former luminous flux more than 95%, behind plated film, change its spectral signature, colour temperature is controlled at 4500K ± 200K, and this rete is high temperature resistant to be reached more than 500 ℃.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model structure of composite membrane schematic diagram
Embodiment:
With reference to the accompanying drawings, the utility model further is described
The utility model is a kind of bulb that is used for operation shadowless lamp, as Fig. 1 as shown in it, it mainly comprises bulb 1, it is characterized in that: described tube face is provided with composite membrane 4, and the bottom of composite membrane is a silicon dioxide layer 2, and the silicon dioxide laminar surface is coated with titanium dioxide layer 3, tube face can be provided with 4-6 layer composite membrane, the thickness of silicon dioxide layer can be 1.2 μ m-2.4 μ m, and the thickness of titanium dioxide layer can be 1.2 μ m-2.4 μ m, and described bulb can be the low pressure halogen bulb.
In specific embodiment, adopt the low pressure halogen bulb, its tube face is coated with 5 layers of composite membrane of being made up of silicon dioxide layer and titanium dioxide layer, the thickness of silicon dioxide layer and titanium dioxide layer is 1.3 μ m, it can keep the former luminous flux more than 95%, behind plated film, changes its spectral signature, colour temperature is controlled at 4500K ± 200K, and this rete is high temperature resistant to be reached more than 500 ℃.
