[0002] LED light strips are lamps that use multiple light-emitting diodes arranged side by side as light sources. Generally, silver glue or white glue is used to solidify the semiconductor LED onto the bracket, and then the chip and circuit board are connected with silver wire or gold wire. The surrounding area is sealed with epoxy resin to protect the internal core wire, and finally the shell is installed. Because LED light strips generate heat when emitting light, heat dissipation is required to ensure the service life of the LED light strip. Existing equipment only dissipates heat by setting through holes between each adjacent LED light. The through holes are single-oriented and the heat dissipation effect is poor.

[0003] For example (publication number CN108534000A) an assembled LED light bar with good heat dissipation effect includes an LED light bar bracket, a first LED light bar, a second LED light bar and a power supply component, the first LED light bar is fixedly arranged on the LED light bar bracket, the second LED light bar is fixedly arranged on the LED light bar bracket, the first LED light bar and the second LED light bar are connected, the shape formed by the connection between the first LED light bar and the second LED light bar is the same as the shape of the LED light bar bracket, and the power supply component is connected to the first LED light bar. This device solves the problem that the existing LED light bar cannot dissipate heat when used, but the light bar only dissipates heat by setting through holes, and the single guide makes the heat dissipation efficiency low and the effect is not good.

[0024] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0025] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0026] The connection method can be bonding, welding, bolt connection and other existing methods, depending on actual needs. Example

[0027] like Figures 1 to 5 As shown, this embodiment includes:

[0028] The fixing plate 1 is easy to install. The shape of the bottom of the fixing plate 1 can be changed according to the usage or environment of the LED light strip body 2, so that the combined LED light strip body 2 is easier to fix. The fixing plate 1 shown in the figure is only one of the states. The bottom of the fixing plate 1 can be set in an arc shape to make it easier to fix with the cylindrical structure.

[0029] A rectangular pipe 6 is embedded inside the fixed plate 1 for ventilation and heat dissipation. Both ends of the pipe 6 are provided with funnel-shaped inclined grooves. The port of the funnel-shaped pipe 6 is intended to increase the air flow rate inside the pipe 6 by suddenly reducing the cross-sectional area of ​​air circulation, thereby forming a relative airflow to cool down the heat generated by the LED lamp source.

[0030] A plurality of circular tubes 3 are arranged at equal intervals, and the plurality of circular tubes 3 are embedded in the side wall of the fixed plate 1 perpendicular to the pipe 6. The circular tubes 3 penetrate the fixed plate 1 and are connected with the pipe 6. A connecting block for guiding is provided between each circular tube 3. The overall structure of the connecting block is an isosceles trapezoid. A plurality of connecting blocks with isosceles trapezoidal structures are evenly arranged at equal intervals inside the pipe 6, which can always keep the change of the internal cross-section of the pipe 6, thereby regulating the air flow rate inside the pipe 6. Moreover, because the circular tubes 3 vertically penetrate the pipe 6 but are not connected with the pipe 6, they will not affect the airflow inside the pipe 6, and are easy to use.

[0031] The LED light strip body 2 is assembled and fixed on the top of the fixing plate 1. Each light source inside the LED light strip body 2 is connected to a high-efficiency metal heat-conducting rod. The metal heat-conducting rod passes through the pipe 6 and extends to the inside thereof, and is connected to a heat-conducting rod 13 made of a high-efficiency heat-conducting metal. The other end of the heat-conducting rod 13 is fixed to the sleeve 12, and the sleeve 12 is sleeved on the outer peripheral side of the heat dissipation pipe 11. The heat dissipation pipe 11, the sleeve 12 and the heat-conducting rod 13 are all made of the same material as the heat-conducting rod to facilitate heat dissipation.

[0032] Connecting pipes 10 are fixed at both ends of the heat dissipation pipe 11, and the connecting pipe 10 is connected to the trumpet-shaped circular pipe 3 that penetrates the pipeline 6. The longitudinal airflow passes through the connected heat dissipation pipe 11 through the circular pipe 3, and cooperates with the airflow inside the pipeline 6 to accelerate the dissipation of the heat transferred to the surface of the heat dissipation pipe 11, thereby improving the heat dissipation efficiency of the LED light strip body 2.

[0033] In order to facilitate assembly and installation, fixing blocks 4 and fixing ears 5 are respectively arranged at the ends of the fixing plates 1. The fixing blocks 4 are grouped in pairs, and a through-type circular hole 7 is arranged in the middle of the fixing blocks 4 and the fixing ears 5. The circular hole 7 is penetrated by a fastener 8 to connect the fixing block 4 and the fixing ear 5. A fixing cap 9 is arranged at the bottom of the fastener 8 to complete the connection between different fixing plates 1. Through the symmetrically arranged fixing blocks 4, the connection tendency can be selected according to the actual usage situation, which is convenient for use.

[0034] The LED light strip body 2 is a conventional instrument, and its working principle, size and model are irrelevant to the function of the present application, so no further description will be given. The control method of the present invention is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0035] How it works

[0036] The assembled LED light bar with good heat dissipation effect is used. When using the device, different fixing plates 1 are combined and fixed by fasteners 8 and fixing caps 9, and then the power lines of the LED light bar body 2 assembled on the fixing plates 1 are connected in series. After completing the connection of the fixing plates 1, the power lines are connected to the power supply, and the light is emitted under the control of the switch.
