When the light source 3 rotates, the first teeth 34 slide the second teeth 441 and the mounting plate 44 toward or away from the guide plate.
When the light source 3 is rotated to adjust the light emitting part 31 to rotate in a direction away from the light guide plate 2, the light emitting part 31 gradually moves in a direction away from the light guide plate 2, the light emitting part 31 emits light to generate heat, and thus the heat between the two baffles 4 gradually increases; at this time, the light source 3 drives the mounting plate 44 to move towards the direction close to the light guide plate 2 through the first convex teeth 34 and the second convex teeth 441, so that the second heat dissipation holes 43 are gradually separated from the mounting plate 44, and the second heat dissipation holes 43 further improve the heat dissipation effect between the two baffles 4.
The baffle 4 with the second heat dissipation holes 43 has a guide groove 45 on one side close to the light source 3, a sliding rod 442 is fixed on one side of the mounting plate 44 close to the guide groove 45, the sliding rod 442 is slidably connected with the guide groove 45, and the guide groove 45 is a dovetail groove. When the mounting plate 44 moves in a direction to approach or move away from the light guide plate 2, the sliding rod 442 slides in the guide groove 45, and the guide groove 45 provides a guide function for the movement of the sliding rod 442 and the mounting plate 44.
Referring to fig. 2 and 4, an air hole 5 is formed in a side wall of the frame 1 away from the panel 11, a receiving groove 51 is formed in a side wall of the air hole 5, a receiving plate 52 for closing the air hole 5 is disposed in the air hole 5, and one end of the receiving plate 52 close to the receiving groove 51 extends into the receiving groove 51. A driving shaft 53 is arranged in the bearing groove 51, two ends of the driving shaft 53 respectively penetrate through the side wall of the frame 1, and one end of the driving shaft 53 close to the lamp source 3 is fixedly connected with a cylindrical elastic block 54. A circular shape joint groove 55 is seted up to a frame 1 inside wall near elastic block 54, and drive shaft 53, elastic block 54, the equal coaxial setting in joint groove 55, elastic block 54 and joint groove 55 joint.
The driving shaft 53 is arranged on the outer side wall of the bearing groove 51 and wound with a driving rope 56, and one end of the driving rope 56 far away from the driving shaft 53 is fixedly connected with one side surface of the bearing plate 52 close to the driving shaft 53. Two mounting grooves 57 are formed in one side wall of the air vent 5 far away from the bearing groove 51, a spring 58 is arranged in each mounting groove 57, one end of each spring 58 is fixedly connected with one side surface of the bearing plate 52 far away from the driving shaft 53, and the other end of each spring is fixedly connected with the bottom wall of the corresponding mounting groove 57. The sum of the elastic forces of the two springs 58 is larger than the frictional force of the elastic block 54 engaging with the engaging groove 55.
When the heat in the frame 1 is too high, the driving shaft 53 is pushed towards the direction in the frame 1, so that the driving shaft 53 drives the elastic block 54 to move towards the direction far away from the clamping groove 55 until the elastic block 54 is separated from the clamping groove 55; then, the driving shaft 53 is rotated to enable the driving shaft 53 to wind the driving rope 56, so that the driving rope 56 pulls the bearing plate 52 to move towards the direction close to the inside of the bearing groove 51, at the moment, the spring 58 is stretched, and then the driving shaft 53 is pulled towards the direction far away from the inside of the frame 1 until the elastic block 54 is clamped with the clamping groove 55; the air holes 5 can play a role in heat dissipation on the frame 1.
Since the elastic force of the spring 58 is greater than the frictional force of the elastic block 54 engaging with the engaging groove 55, the receiving plate 52 gradually moves away from the receiving groove 51 under the action of the spring 58, and in the process, the ventilation area of the ventilation hole 5 gradually decreases until the receiving plate 52 contacts with a side wall of the ventilation hole 5 away from the driving shaft 53. The situation that the staff forget to seal the air holes 5 is reduced, so that the external dust impurities are less and enter the frame 1, and the situation that the dust impurities influence the light-emitting effect of the thin lamp box is reduced.
The implementation principle of the side light-emitting system of the thin lamp box in the embodiment of the application is as follows: when the light intensity of the thin light box needs to be adjusted, the adjusting shaft 33 is rotated, so that the adjusting shaft 33 drives the light emitting part 31 to move towards the direction close to or away from the light guide plate 2, the larger the area of the light emitting part 31 irradiating the light guide plate 2 is, the better the light display effect of the light guide plate 2 is, and the stronger the light intensity of the thin light box is.
When the heat in the frame 1 is too high, the driving shaft 53 is pushed towards the direction in the frame 1 until the elastic block 54 is separated from the clamping groove 55; then, the driving shaft 53 is rotated to enable the driving rope 56 to pull the bearing plate 52 to move towards the direction close to the interior of the bearing groove 51 until the air holes 5 are opened to the required area, and then the driving shaft 53 is pulled towards the direction far away from the interior of the frame 1 until the elastic block 54 is clamped with the clamping groove 55; at this time, the heat dissipation area of the air holes 5 is increased, and air inside and outside the frame 1 circulates, so that heat dissipation is facilitated inside the frame 1.
Because the elastic force of the spring 58 is greater than the frictional force of the elastic block 54 and the clamping groove 55, the bearing plate 52 gradually moves in the direction away from the bearing groove 51 under the action of the spring 58, and at the moment, the elastic block 54 slowly rotates in the clamping groove 55; in the process, the ventilation area of the ventilation holes 5 is gradually reduced until the bearing plate 52 contacts one side wall of the ventilation holes 5 far away from the driving shaft 53, so that the situation that the staff forget to close the ventilation holes 5 is reduced.
Example two:
the embodiment of the application discloses a side light-emitting system of a thin lamp box. Referring to fig. 5, the difference from the first embodiment is that two light sources 3 are disposed between each two baffle plates 4. When the luminous intensity of thin lamp house of needs control weakens, control two lamp sources 3 and rotate in opposite directions, two lamp sources 3 rotate in opposite directions and are convenient for the light that the reduction that two lamp sources 3 are comparatively placed in the middle shines light guide plate 2, so be convenient for thin lamp house comparatively even luminous.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
