Description

Illuminator for medical examination equipped White LED Lamp}

The present invention relates to a medical luminaire, and in particular, a white light emitting device is mounted on a medical luminaire such as an otoscope or an ophthalmoscope, minimizing power consumption, and bringing the illumination light closer to natural light to provide a more accurate field of view to the user. The present invention relates to a medical lighting device having a light emitting element that can be secured.

Medical lighting equipment is a device that is used by doctors to examine the state of each human body part inserted into the main parts of the human body such as the ear, nose, eyes, and neck of the patient. Generally, each medical lighting device is inserted into a human body part. A light emitting device for illuminating the light emitting device is provided, and a conventional halogen lamp has been adopted as a conventional light emitting device.

1 is a perspective view showing a conventional medical lighting device, Figure 2 is a drive circuit diagram of a halogen lamp, wherein the medical lighting device of Figure 1 shows an otoscope as an example.

Reference numeral 1 is a head, 2 is a main body, 3 is an insert, 4 is a magnifying glass, 5 is an on / off switch, 6 is a halogen lamp, and 7 is a power supply means.

In the conventional medical lighting fixture, the head 1 of the otoscope shown as an example is an insertion portion 3 is inserted into the ear of a person, and through the insertion portion 3 through a magnifying glass that enlarges a certain area of view secured ( 4) and a halogen lamp 6 that emits light for illumination of a predetermined area secured by the insertion part 3. The main body 2 integrally provided with the head 1 includes a power supply means 7 such as a battery or a rechargeable battery therein, and an on / off power source generated from the power supply means 7. On / off switch (5).

That is, in the conventional otoscope, when the user inserts the insertion part 3 into the patient's ear to examine the patient and turns on the on / off switch 5, the power output from the power supply means 7 is halogen lamp 6 Turn on). Therefore, the light emitted from the halogen lamp 6 is irradiated to a certain area of the body directed by the insertion portion 3, so that the user can directly check through the magnifying glass (4).

However, since the halogen lamp applied to such a conventional medical lighting fixture is caught in the user's field of view as the red light due to the heat generated by the filament, it is not easy to accurately observe the user and consumes a lot of power due to high power consumption. The life of rechargeable batteries is short. In addition, since halogen lamps are filled with gases other than filaments, their lifespan is reduced due to heat generation and other environments, so additional costs are paid to the user, and the main body and head are integrally formed. When observing the neck area, there is a problem that you need to purchase a new total of the probate head including the main body.

Therefore, the present invention devised to solve the above problems has a low power consumption, a semi-permanent life by having a white light emitting device, so that the main body and the head can be separated and combined so that only the head can be replaced according to the intended use. An object of the present invention is to provide a medical lighting device having a light emitting device.
