Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the backlight indoor lighting lamp comprises a bearing plate 1, a lampshade 2, a first light transmission strip 3, a second light transmission strip 4, a third light transmission strip 5, a light emitting component 6, a first light barrier 7, a traction rope 8, a limiting block 9, a reset spring 10, a second light barrier 11, a first through hole 12, a second through hole 13 and a groove 14, wherein the lampshade 2 is installed above the bearing plate 1, the first light transmission strip 3, the second light transmission strip 4 and the third light transmission strip 5 are installed on the surface of the lampshade 2 in an embedded mode, the light emitting component 6 is installed above the bearing plate 1 and is located inside the lampshade 2, the first light barrier 7 is arranged on the front side and the rear side inside the lampshade 2, the second light barrier 11 is arranged on the left side and the right side inside the lampshade 2, the traction rope 8 is connected to one side of the first light barrier 7 and one side of the second light barrier 11, the reset spring 10 is installed on the lower surfaces of the first light barrier 7 and the second, and the lower extreme of reset spring 10 is embedded to be installed in the inside of bearing plate 1, and first through-hole 12 and second through-hole 13 have been seted up to the lower surface of bearing plate 1, and the outside of first through-hole 12 and second through-hole 13 all is provided with recess 14.

The left and right sides of lamp shade 2 all is provided with 1 third printing opacity strip 5, and the upper surface symmetry of lamp shade 2 is provided with 4 first printing opacity strips 3 to the front and back surface of lamp shade 2 all is provided with 2 second printing opacity strips 4, thereby is convenient for light and sees through around lamp shade 2 uniformly, realizes carrying out the light filling to ceiling and side.

First printing opacity strip 3, second printing opacity strip 4 and third printing opacity strip 5 all set up to rectangular form structure, and first printing opacity strip 3 is located the upper surface of lamp shade 2, and second printing opacity strip 4 and third printing opacity strip 5 are located 4 sides of lamp shade 2, and rectangular form structure makes the light transmission area increase, and lamp shade 2 sets up to trapezium structure, makes second printing opacity strip 4 and third printing opacity strip 5 of side beat light to the top, avoids light to shine downwards, improves the effect that light throws.

The lower ends of the first light barrier 7 and the second light barrier 11 are rotatably connected with the lampshade 2, the first light barrier 7 and the second light barrier 11 are respectively located on the outer side of the light emitting component 6, the first light barrier 7 and the second light barrier 11 can rotate in the lampshade 2, and therefore when the first light barrier 7 and the second light barrier are pulled downwards, the second light transmission strip 4 or the third light transmission strip 5 cannot be shielded, and illumination emitted by the light emitting component 6 is emitted outwards.

The outside of haulage rope 8 is fixed with stopper 9, and stopper 9 sets up to "L" type structure to the distance of haulage rope 8 upper end and stopper 9 equals the thickness of layer board 1.

The groove 14 is of a structure shaped like a Chinese character 'kou', the groove is located on the outer sides of the first through opening 12 and the second through opening 13, the first through opening 12 and the second through opening 13 are of structures with equal calibers, the calibers of the first through opening 12 and the second through opening 13 are larger than the length of the limiting block 9, the limiting block 9 can freely move up and down in the first through opening 12 or the second through opening 13, and then the traction rope 8 can be pulled, so that the limiting block 9 can be clamped in the groove 14 at the corresponding position.

The working principle is as follows: when the backlight indoor lighting lamp is used, firstly, the backlight indoor lighting lamp is hoisted and installed through a threaded hole above a lampshade 2, a power supply of a light-emitting component 6 is threaded from the position right below a bearing plate 1, when the backlight indoor lighting lamp needs to be used, firstly, the power supply is turned on, the light-emitting component 6 emits light to irradiate, and light penetrates through a first light-transmitting strip 3, a second light-transmitting strip 4 and a third light-transmitting strip 5, at the moment, the second light-transmitting strip 4 and the third light-transmitting strip 5 are respectively shielded by a first light-shielding plate 7 and a second light-shielding plate 11, so that the light can only be emitted through the first light-transmitting strip 3, the light is incident on a ceiling, the light is prevented from being directly projected underground, dazzled light is avoided, and;

when needs carry out the light filling to the side, 8 pulldowns of haulage rope can be handed, haulage rope 8 drives barn door one 7 and stopper 9 downstream, barn door one 7 rotates downwards promptly, take stopper 9 from the inside of lamp shade 2 downwards, until barn door one 7 is the horizontality completely, reset spring 10 is compressed in the inside of bearing board 1 this moment, stopper 9 is located the below of bearing board 1, with stopper 9 terminal card can in recess 14, thereby barn door one 7 fixes, prevent the bounce-back, can go on down barn door two 11 with the same reason, carry out the light filling to the wall in different position, improve the comfort level of ambient light illumination compensation, whole practicality has been increased.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
