Description

Technical Field

[0001] The utility model relates to a light-shielding structure, in particular to a light-emitting component of a light source module with a light-shielding function and an LED and fluorescent composite light source. Background Technique

[0002] With the increasing demand for medical light source modules by people, the use of LED and fluorescent composite modules has gradually occupied more market space. In the LED and fluorescent composite module, the two light sources of LED and fluorescent inside are processed by a lens and then converge and emit light at the light-emitting port. In this process, in order to accurately collect the light beam at the focal plane of the LED and fluorescent composite module, a light beam fixing adapter seat must be used to accurately position the light beam.

[0003] Such as Figure 1 and Figure 2 As shown, at the light-emitting port position of the LED and fluorescent composite module, a light beam fixing adapter seat 1 is provided to facilitate the insertion of the light beam 3, which can better receive the light output by the LED and fluorescent composite module. Among them, although the light beam fixing adapter seat plays a partial role in light shielding, since the light beam insertion hole 2 is a straight-through hole, when the light beam 3 is not inserted, the light generated by the LED and fluorescent composite module will still emit energy outward through the light beam insertion hole 2.

[0004] This structure has the following problems: Since the energy of the light output by the LED and fluorescent composite module is relatively high and converges at the focal plane 4 of the LED and fluorescent composite module, when looking directly at the module when the light beam is not inserted into the light beam fixing adapter seat, the light generated by the LED and fluorescent composite module will cause harm to the human eye; and if people stand at the light-emitting port position of the LED and fluorescent composite module for a long time, in the illuminated area, it may burn clothes or cause burns to the skin. Content of the Utility Model

[0005] In view of the above technical problems, the utility model discloses a light-emitting component of a light source module with a light-shielding function and an LED and fluorescent composite light source, which solves the problem of no shielding at the light-emitting port of the LED and fluorescent composite module and causing harm.

[0006] For this, the technical solution of the utility model is as follows:

[0007] A light-emitting component of a light source module with a light-shielding function, which comprises a light-shielding fixing seat, a movable light-shielding sheet and a light beam fixing adapter seat;

[0008] The light-shielding fixed seat is provided with a light guide beam channel. The middle part of the light guide beam fixed adapter seat is provided with a light guide beam fixing groove. The light beam channel and the light guide beam fixing groove are coaxially arranged. The light-shielding fixed seat is connected to the light guide beam fixed adapter seat. The movable light-shielding piece is located between the light-shielding fixed seat and the light guide beam fixed adapter seat and on the optical path between the light guide beam channel and the light guide beam fixing groove. A cavity for the rotation of the movable light-shielding piece is provided between the light guide beam fixed adapter seat and the light-shielding fixed seat. The upper side of the movable light-shielding piece is rotatably connected to the inner side of the light-shielding fixed seat. When the light guide beam is inserted into the light guide beam channel, the movable light-shielding piece is driven to rotate to expose the light beam channel, so that the light guide beam is inserted into the light guide beam fixing groove.

[0009] With this technical solution, when the light guide beam is not inserted, the movable light-shielding piece blocks the light beam channel. When the light guide beam is inserted, the light guide beam pushes the movable light-shielding piece to rotate, and the light beam channel is opened, so that the light guide beam can be smoothly inserted into the light guide beam fixing groove. By using the rotation of the movable light-shielding piece, the shielding or exposure of the light beam channel is realized, and the problem that the light outlet of the LED and fluorescent composite module has no shielding and causes harm to people is solved.

[0010] As a further improvement of the present invention, the inner side of the light-shielding fixed seat is provided with a light-shielding piece mounting seat. The upper side of the movable light-shielding piece is rotatably connected to the light-shielding piece mounting seat. The light-shielding piece mounting seat is provided with an introduction channel coaxially arranged with the light guide beam channel.

[0011] As a further improvement of the present invention, one side of the movable light-shielding piece is rotatably connected to the light-shielding piece mounting seat through a pin.

[0012] As a further improvement of the present invention, the middle part of the light-shielding piece mounting seat is provided with a fixed stop block, and the introduction channel is located in the middle of the fixed stop block.

[0013] As a further improvement of the utility model, the fixed block is provided with a fixed magnet, the movable light shielding sheet is located on the inner side of the fixed block (the inner side is the side facing the light guide fixed adapter), and is provided with a movable magnet, and the magnetic poles of the fixed magnet and the movable magnet are opposite. With this technical solution, by setting a fixed magnet on the fixed block, and correspondingly setting a movable magnet on the movable light shielding sheet, when the light guide is not inserted, the movable light shielding sheet blocks the light beam channel under the magnetic force of the fixed magnet and the movable magnet, so that the light of the LED and fluorescent composite module will not be emitted, and will not cause harm to people. When the light guide is inserted into the light beam channel and contacts the movable light shielding sheet, the light guide pushes the movable light shielding sheet to rotate, thereby opening the light beam channel, and the light guide can be smoothly inserted into the light guide fixed groove. At this time, the movable light shielding sheet is located in the cavity under the obstruction of the light guide. When the light guide is pulled out, the movable light shielding sheet falls down, and under the magnetic force of the fixed magnet and the movable magnet, the light beam channel is blocked again, thereby achieving protection. The entire assembly has a simple structure, low cost and is easy to implement.

[0014] As a further improvement of the present invention, a pin groove is provided on one side of the movable shading sheet, and the pin passes through the pin groove and is connected to the shading sheet mounting seat via a pin fixing screw.

[0015] As a further improvement of the present invention, the movable shading sheet has a U-shaped appearance, and a U-shaped groove for the movable shading sheet to move is provided in the shading sheet mounting seat.

[0016] As a further improvement of the present invention, the fixed magnet is located on the outer surface of the fixed stopper (the outer surface refers to the surface facing the side of the shading fixing seat) and is fixed to the fixed stopper by a fixed magnet cover.

[0017] As a further improvement of the utility model, the movable magnet is located on the movable shading sheet and is fixed to the movable shading sheet by a movable magnet pressure cover. Further, the movable magnet pressure cover is located on the side of the movable shading sheet facing the light guide fixed adapter.

[0018] As a further improvement of the utility model, the fixed magnet cover is fixed to the fixed stopper by screws, and the movable magnet cover is fixed to the movable shading sheet by screws.

[0020] As a further improvement of the present utility model, the light-shielding sheet mounting seat is fixedly connected to the light-shielding fixed seat by screws, and the light-shielding fixed seat is fixedly connected to the light guide beam fixed adapter seat by screws.

[0021] As a further improvement of the present utility model, before the light guide beam is inserted, the movable light-shielding sheet is vertically downwardly arranged to avoid the influence of other installation directions on the magnet polarity.

[0022] As a further improvement of the present utility model, different angles can be adjusted between the light-shielding sheet mounting seat and the light-shielding fixed seat, and the different angles increase in increments of 90°.

[0023] As a further improvement of the present utility model, there are two movable magnets, which are horizontally symmetrically arranged on both sides of the movable light-shielding sheet.

[0024] As a further improvement of the present utility model, there are three fixed magnets, and the three fixed magnets are evenly distributed on the fixed baffle.

[0025] The present utility model discloses an LED and fluorescent composite light source, which includes a light source module light-emitting component with a light-shielding function as described in any one of the above.

[0026] Compared with the prior art, the beneficial effects of the present utility model are as follows:
