Abstract
The utility model relates to a shadowless lamp for operations, which is composed of a lamp cap housing, a light source, a light reflecting mirror, a heat absorbing system, face shield glass and a focusing system, wherein the light source is arranged in the heat absorbing system, the light reflecting mirror is arranged outside the heat absorbing system, and the face shield glass is arranged outside the lamp cap housing. The utility model is characterized in that the light reflecting mirror is formed by overlapping at least 1000 heave light rays formed from at least 1000 mirror surfaces, and a blue coating film is arranged outside the light reflecting mirror. The utility model has the advantages of high shadowless degree, deep illumination and effective color and temperature control, and makes the light rays approximate to natural white light.
Description
Technical field
The utility model relates to a kind of operation shadowless lamp, can be used for belonging to operation shadowless lamp on the operating table of hospital
Technical field.
Background technology
The primary effect of operation shadowless lamp is the shade of eliminating in the operation, the any shade that forms in operating field all will hinder doctor's observation, differentiation and operation to implement, therefore, must guarantee that operating field surface and deep tissue have sufficient illumination, the reflective mirror of 12 traditional hole lamps has 12 heavy light stacks, and common overall reflective shadowless lamp reflective mirror also has only 8～12 heavy light stacks usually.12 hole lamps and common overall reflective shadowless lamp reflective mirror all carry out light stack on same shadow surface, when prolonging shadow surface and move up and down, hot spot can occur not that rounding and stacking fold reduce, and the illumination degree of depth, no shadow degree are undesirable.
The colour temperature of operation shadowless lamp requires generally preferable between 4000K～4500K, light is white in color, light is red partially when being lower than 4000K, capillary not easy to identify and cell tissue, light is blue and green partially partially when being higher than 4500K, can be purple and brown when shining red cell tissue, be easy to generate mistaken diagnosis.
Generally about 3000K, light is red partially for the colour temperature of based on halogen bulb.The method of in the past controlling colour temperature relies on the light blue as the medium of adjusting colour temperature of itself when mainly adopting silicate glass as heat-absorbing material, but this method is a silicate glass is adding the very difficult color of adjusting in man-hour, therefore when the colour temperature of light source not simultaneously, can't adjust photochromic temperature.
Summary of the invention
The purpose of this utility model is a kind of no shadow degree, illumination degree of depth that increases operation shadowless lamp of invention, can control the operation shadowless lamp of photochromic temperature effectively.
For realizing above purpose, the technical solution of the utility model provides a kind of operation shadowless lamp, form by lamp shell, light source, reflective mirror, endothermic system, visor, focusing system, light source is located in the endothermic system, reflective mirror is located at outside the endothermic system, and visor is located at outside the lamp shell, it is characterized in that, described reflective mirror is formed by stacking at least 1000 minute surfaces form 1000 heavy light at least, is provided with blueness and films outside reflective mirror.
Reflective mirror of the present utility model adopts the reflective principle of many minute surfaces, and at least 1000 minute surfaces that utilization CAD/CAM manufactures and designs reflect stack from different perspectives, reach no shadow, and shadow surface forms a light beam up and down, forms the illumination degree of depth thus.The utilization geometric optical theory when light of She Chuing shines the same area from different directions, can be eliminated shade, and the effect that shade is eliminated in the stack of many more light is good more; Under the situation that illumination and no shadow degree can meet the demands, overlap-add region to be extended up and down on same axis, the illumination degree of depth that forms when the illumination depth ratio of Xing Chenging is with layer irradiation operative region thus is dark.
According to using the colorized optical filtering mirror to can be used for adjusting colour temperature in the photography to reach the true reappearance principle of color, coat light blue transparent film in mirror surface, when after light that light source sends arrives reflecting surface by this film, arriving area of illumination by this film again, photochromic temperature can change, can adjust colour temperature by color or thickness, make the method for control colour temperature simple more, effective film.
The utility model has the advantages that no shadow degree height, the illumination degree of depth is dark, can control colour temperature effectively, makes light near natural white light.
Description of drawings
Fig. 1 is a kind of operation shadowless lamp structural representation;
Fig. 2 is the light-source structure schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, be a kind of operation shadowless lamp structural representation, a kind of operation shadowless lamp, form by lamp shell 1, light source 2, reflective mirror 3, endothermic system 4, visor 5, focusing system 6, light source 2 is located in the endothermic system 4, reflective mirror 3 is located at outside the endothermic system 4, and visor 5 is located at outside the lamp shell 1, and described reflective mirror 3 is formed by stacking at least 1000 minute surfaces form 1000 heavy light at least: be provided with blueness and film 7 outside reflective mirror 3.
Elder generation's processing mold, the CAD design data according to light path is input to numerical control machining center, by machining center the minute surface steel is carried out machining, makes mould form polyhedron, then these polyhedrons is carried out grinding and polishing until reaching minute surface.With this mould aluminium sheet is carried out rotary press modelling, form many minute surfaces reflective mirror 3, reflective mirror is carried out plated film or electrochemical polish, to increase reflecting rate.
Film 7 base-material of blueness is a kind of water white coating, dilute with solvent after adding blue pigment according to a certain percentage, be mixed with light blue solution, use spray gun that solution evenly is sprayed on reflective mirror 3 surfaces, through baking oven 150-200 degree baking and curing, form light blue rete 7 in mirror surface.
The utility model adopts on the reflective mirror of operation shadowless lamp, films and adjusts colour temperature, and the depth of the color of filming is related to the index of colour temperature and illumination.The color of filming is blue partially, and colour temperature can be higher, and illumination can weaken thereupon; The color of filming is shallow partially, and colour temperature can be on the low side.The bubble of film coated surface, impurity can influence the index of colour temperature, illumination and presentation quality.
As shown in Figure 2, be the light-source structure schematic diagram, light source is positioned at the axis 8 of many minute surfaces reflective mirror, and light 10 superposes on area of illumination by many minute surfaces reflective mirror 9 reflection backs, its illumination degree of depth area of illumination 11 that is above standard shows and can deepen the degree of depth of throwing light on to the staggered floor design of shadow surface.
