Description

Surgical light

The present invention relates to a surgical light, and more particularly to a surgical light using an LED as a light source.

Please refer to Taiwan Patent Application No. 087119103, "Shadowless Mirror Structure of Surgical Lamp", a surgical lamp head having a front lamp housing and a rear lamp housing, wherein the front lamp housing has a large circular opening in the reverse direction of the rear lamp housing. For the light to be emitted, the front surface of the opening is connected with a circular surface which is larger than the opening. The lower edge of the opening of the inverted bowl mirror is fixed at a small distance from the front glass, and the center of the front glass is round. Hollow-shaped, a disc-shaped portion of the grip is attached to the edge of the central opening; a lamp holder is connected to the center of the front glass; the lamp holder is opposite to the grip, and the bulb and the spare bulb are connected thereto; A cylindrical heat absorbing glass is arranged around the bulb, the height of which covers the uppermost edge of the lamp holder until it approaches the top surface of the mirror to ensure that the light emitted by the bulb or the spare bulb passes through the heat absorbing glass before reaching the mirror. A circular opening at the top end of the mirror is approximately equivalent to the inner diameter of the cylindrical heat absorbing glass to facilitate the scattering of heat to the outer side of the surgical lamp head after the aluminum alloy is made of the lamp housing. The mirror emits the received light from the front glass and focuses it about one meter in front of the center of the front glass to form a cylindrical illumination range.

The surgical lamp head is a halogen light bulb as a light source. Since the illumination angle of the halogen bulb is larger than the illumination angle of the LED light source, the depth of the mirror of the surgical lamp head is conventionally known. The degree is deeper to effectively utilize the illumination of the halogen bulb, but since the halogen bulb has low photoelectric conversion efficiency, a large amount of heat is emitted while the halogen bulb emits light, and therefore, the surgical lamp head is provided with the heat absorbing glass to absorb the halogen. The heat emitted by the bulb, and a circular opening is provided at the top end of the mirror to dissipate the heat, and the illumination of the partial halogen bulb is sacrificed, and the energy generated by the halogen bulb is mostly released in the form of heat. Therefore, conventional surgical heads consume considerable power.

The photoelectric conversion efficiency of LED is better than that of halogen bulb. Therefore, replacing the halogen bulb with LED can reduce the power consumption of the surgical lamp head. However, the illumination angle of LED is generally between 120 degrees and 130 degrees. It is impossible to replace the halogen bulb with a single LED. The full-circumference light of a plurality of LED analog halogen bulbs is required as a light source of a conventional surgical lamp head. However, if a halogen bulb of a conventional surgical lamp head is replaced by a plurality of LEDs, a spot shape such as Annex 1 is formed, which is due to The LED has a small illumination angle and strong illuminance directivity. Therefore, the spot reflected by the reflector will generate many bright spots, and it will not be able to present a uniform circular spot, but will exhibit an irregular shape of the spot, and the uniformity of the spot is relatively low. Meets the specifications of international regulations for surgical lights.

The main object of the present invention is to uniformly reflect the illumination of the LED light source by the reflector to form a high uniformity and shadowless circular spot with a diameter of 19 cm on an area other than 1000 mm. The illumination intensity of a single group of LED light sources and reflectors can reach 13,000 lux, so only 8 sets of LED light sources and reflectors are needed to meet the requirements of 100,000 lux required by the international regulations of surgical lamps, which can effectively reduce the consumption of surgical lamps. Electricity.

A surgical lamp of the present invention comprises a reflector and an LED light source, the reflector has a central mirror, a first reflective area and a second reflective area, the central mirror is located at the center of the reflector, the center is reflective The mirror has a central vertical axis, the first reflective area surrounding the central mirror, The second reflective area surrounds the first reflective area, and the first reflective area is located between the central reflective mirror and the second reflective area, the first reflective area has a plurality of first reflective modules, each of the first The reflective module has a first connecting edge, a second connecting edge and a plurality of first mirrors, and the first mirrors are located between the first connecting edge and the second connecting edge, each of the first connections Connecting the central mirrors, each of the first mirrors is a trapezoidal mirror, and each of the first mirrors is inclined at a first angle relative to the central mirror toward the central vertical axis, and the first mirrors are The first angle is increased by each of the first mirrors adjacent to the central mirror toward the first mirrors adjacent to the second reflective area, and the second reflective area has a plurality of second reflective modules, each of which The second reflective module has a third connecting edge, a fourth connecting edge and a plurality of second mirrors, and the second mirrors are located between the third connecting edge and the fourth connecting edge, wherein each of the second reflecting edges The length of the second connecting edge is greater than the length of each of the third connecting edges And the plurality of third connecting edges are connected to a second connecting side, each of the second mirrors is a trapezoidal mirror, and each of the second mirrors is inclined at a second angle with respect to the central mirror toward the central vertical axis, The second angle of the second mirror is increased by each of the second mirrors adjacent to the first reflecting area toward the second mirror adjacent to the fourth connecting side, and each of the second angles is greater than each of the second mirrors In a first angle, the LED light source is disposed below the central mirror.
