[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1-4As shown, a COB light strip structure capable of side-emitting light includes a light strip 1 provided with light beads 11, and also includes a film 3 movable on the light strip 1 and in a raised state, and a rubber strip 2 is fixedly mounted on the film 3;

[0024] A plurality of groups of symmetrically arranged support plates 31 are fixedly mounted on the film 3 , and support holes 311 for the support plates 31 to slide are provided on the light bar 1 .

[0025] Specifically, the light strip 1 and the light beads 11 are both existing technologies and are not described in detail here. The film 3 is specifically made of transparent rubber, and its surface has a reflective effect, while the rubber strip 2 uses the rubber diffuser material in the existing technology and does not have reflective properties.

[0026] Furthermore, the support plate 31 is made of hard transparent plastic, so that the support plate 31 has a light-transmitting effect and also has the effect of increasing the supporting stability of the film 3 and the rubber strip 2 .

[0027] By using the raised rubber strip 2 to leave a cavity section between it and the light strip 1, on the one hand, the amount of glue used can be reduced. On the other hand, when the lamp beads 11 in the cavity are working, the heat generated by them can be transferred and dissipated through the air, reducing the high heat generated by the direct contact between the lamp beads 11 and the rubber strip 2. The light source can still act on the rubber strip 2 after passing through the film 3, so that the rubber strip 2 maintains the luminous effect, and the light source generated by the lamp beads 11 is transferred to the gap between the two sides of the film 3 and the light strip 1, and is matched with a transparent support plate 31, so that both sides of the light strip can emit light normally. At the same time, the reflective effect after the light shines on the surface of the film 3 makes part of the light source reflected into the gap between the film 3 and the light strip 1, and cooperates with the original luminous effect on both sides of the light strip, so that the light effect emitted from both sides of the light strip is stronger, thereby improving the side light display effect of the light strip and improving the luminous efficiency.

[0028] As an embodiment further provided by the present invention, an elastic member 32 is fixedly mounted on the end of the support plate 31 , and a clamping hole 321 for clamping with the elastic member 32 is opened in the support hole 311 .

[0029] Specifically, the elastic member 32 is a triangular elastic metal sheet, and the deformation position is one of the bases of the triangle.

[0030] By manually pressing both sides of the rubber strip 2, the support plate 31 is made to penetrate into the support hole 311, and the elastic member 32 is deformed and sequentially snapped into the snap holes 321 arranged in an array. An obvious sound is emitted in the snap connection state to serve as a warning. On the one hand, the connection between the support plate 31 and the light strip 1 is made more stable. On the other hand, the reflective inclination angle of the film 3 gradually stretched close to the lamp bead 11 is increased, and the reflection of the film 3 is reduced. Gathering on the lamp bead 11 reduces the reflected light source of the film 3, which is irradiated to both sides of the light strip, and the luminous brightness on both sides of the light strip is increased, so that the lighting effect is adjustable.

[0031] As another embodiment further provided by the present invention, a plurality of baffles 33 are fixedly mounted on the light bar 1 , and the baffles 33 are located on the inner side of the adjacent support plates 31 .

[0032] Specifically, the baffle 33 is also made of transparent hard plastic so that it does not interfere with the irradiation of the reflected light, and there is a gap between the baffle 33 on the inner side of the support plate 31 to allow air to flow through the gap, and when the elastic member 32 is engaged with the last card hole 321 in the support hole 311, the length of the baffle 33 is equal to the length of the support plate 31 on the light strip 1.

[0033] By setting the baffle plate 33 between two adjacent support plates 31 on the same side, the light strip can be cut at the position of the baffle plate 33 when being cut for use, thereby ensuring the normal use of the light strip. In addition, the gap between the baffle plate 33 and the support plate 31 can enhance air circulation, thereby providing a good heat dissipation effect on the inside of the light strip.

[0034] As another embodiment further provided by the present invention, a heat conducting plate 34 is fixedly mounted on the end of the support plate 31 , and a storage hole 341 for storing the heat conducting plate 34 is opened on the light bar 1 .

[0035] Specifically, the storage hole 341 is located inside the lamp bead 11 and will not affect the normal power supply of the lamp bead 11 , and the heat conducting plate 34 fills the entire storage hole 341 .

[0036] The heat generated by the lamp beads 11 is transferred to the heat conducting plate 34 through the heat conducting plate 34 located at the position of the lamp beads 11, and is transmitted to the outside air through the support plate 31, so as to increase the heat dissipation efficiency of the lamp beads 11 and improve the working safety of the light strip.

[0037] As another embodiment further provided by the present invention, the heat conducting plates 34 on each group of support plates 31 are mutually in conflict with each other.

[0038] Specifically, the heat conducting plate 34 is made of elastic metal, and the heat conducting plates 34 on the two support plates 31 fit each other in the storage hole 341 .

[0039] The heat conducting plates 34 that fit each other are used to efficiently absorb the temperature generated by the lamp beads 11 during operation, and the heat conducting plates 34 are used to quickly transfer the temperature to the two support plates 31 , so that the outside air preferentially cools the temperature transferred to the support plates 31 .

[0040] As another embodiment further provided by the present invention, the heat conducting plate 34 slides along with the supporting plate 31 and is embedded in the supporting hole 311 .

[0041] When the support plate 31 gradually penetrates into the support hole 311, the heat conducting plate 34 is pulled and slid into the support hole 311 to be embedded, so that the heat conducting plate 34 is additionally fastened to the clamping installation of the support plate 31, so that after gradually pressing the film 3, the support plate 31 becomes more stable, thereby increasing the stability of the light strip during use. At the same time, when the elastic member 32 is clamped with the last clamping hole 321, the two heat conducting plates 34 still remain in contact to ensure the dissipation of heat.

[0042] Working principle: By manually pressing the two sides of the rubber strip 2, the support plate 31 is made to penetrate into the support hole 311, and the elastic member 32 is deformed and sequentially snapped into the snap holes 321 arranged in the array. On the one hand, the connection between the support plate 31 and the light strip 1 is made more stable, and on the other hand, the reflective inclination angle of the film 3 gradually stretched close to the lamp bead 11 is increased, and the reflection of the film 3 is reduced. The situation of gathering on the lamp bead 11 makes more reflected light sources irradiated to both sides of the light strip, increases the luminous brightness on both sides of the light strip, and realizes adjustable lighting effect. The baffle 33 arranged between the two adjacent support plates 31 on the same side enables the gap between the baffle 33 and the support plate 31 to enhance air circulation, so that the inner side of the light strip has a good heat dissipation effect.

[0043] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
