Description

Operating lamp and lighting unit thereof
Technical field
The utility model is relevant a kind of operating lamp, refers to a kind of operating lamp that a plurality of led light source groups can be reflected fast with focusing function that has especially.Especially, the utility model further comprises a kind of lighting unit that is used for operating lamp.
Background technology
Press in the operation, operating lamp is for providing illumination indispensable important instrument.The known structure of at present general operating lamp can generally be divided into single light source simple reflector structure, and multiple light courcess structure, this single light source simple reflector structure is to adopt for example single light source of 150W of high power, Halogen lamp LED or gas discharge type lamp (High Intensity Discharge for example, abbreviate HID as) be that light source is by mirror reflects optically focused, to reach application target.And the multiple light courcess structure to be to use power be a plurality of light sources of 30-50W, for example Halogen lamp LED or gas discharge type lamp form the multiple tracks light beam, via structural adjustment light beam are concentrated on a projection surface optically focused again, to reach application target; When this multiple light courcess structure is implemented, a plurality of light sources can there be device at single lamp body, or after having individual light source of one's own a lampet body, more a plurality of little lamp bodies be assembled a big lamp body.
Along with the continuous research and development of high-brightness LED, existing dealer applies to operating lamp with LED, because the only about 1.5W-3W of indivedual power of LED is little a lot of more than aforementioned Halogen lamp LED or gas discharge type lamp.Therefore, LED only can adopt the multiple light courcess structure, and enough illumination can be provided, this measure will cause LED operating lamp structure will than aforementioned single light source simple reflector structure and multiple light courcess complex structure many.
In fact, the light temperature that LED came out is extremely low, the demand that meets very much the operation illumination, the color rendering of while LED, colour temperature is also increasingly mature, must become the main flow of operation illumination of future generation, but because of operating lamp need can focus in certain distance at any time, focusing (adjustment irradiated area), so can't be as the beam angle of LED street lamp or general illumination adopt fixed, the LED operating lamp needs multidirectional LED to be gathered together in addition, therefore can't use the big light source of aggregation type LED, LED street lamp for example, probe into it because of being to be, can't receive light because of big light source and become a kind of light beam that meets demand, therefore on practice, the LED operating lamp need use many LED small light sources, and this measure will cause on the structure complicated.
Moreover the light temperature that LED comes out is extremely low, but the heat that itself produced must effectively guide away, otherwise accumulation of heat surpasses this LED nominal operation temperature, will cause LED deterioration rapidly, and reduces luminous flux, even burn, and then influence service life.Therefore, how the heat energy that tens of LEDs produced effectively being dispelled the heat, is that the important topic that must solve is gone up in the design of LED operating lamp.
Especially, LED institute throw light is a kind of extremely strong light that points to, and at present it is become efficient beam and is applied on the operating lamp, nothing more than adopting lens to receive light and mirror reflects receipts light dual mode.Wherein, the lens mode is comparatively direct, and structure is comparatively simple, but because of the lens mode is that a kind of point-like high light directly emits, so that medical personnel will be very dazzling when looking at lamp body straight; And reflective receipts light can be incident upon the direct sunshine of LED on the speculum, and via the particular design of reflecting surface, for example make reverberation form one light beam uniformly and cast out as the lattice face, so medical personnel are the light of a reflecting surface when looking at straight, rather than the point-like high light.Therefore, by aforesaid explanation, be appreciated that mirror reflects receipts light mode will be better than lens and receive the light mode, but so much speculum sets up, adjusts problems such as control, and heat dissipation problem, is the difficult problem that relevant dealer demands urgently overcoming.
