[0030] The following is a detailed description of the working principle of this adjustable LEC cold light source.

[0031] like Figure 1-5As shown, when in use, first, fixing holes of the same size as the mounting blocks 96 are opened on the left and right sides of the mounting plate of the mounting height device, and then the two ends of the clamping plate 92 are clamped on the mounting plate respectively, and the rotating knob 94 drives the bidirectional screw 93 to rotate, so that the clamping plates 92 on the left and right sides move toward the middle through the threaded sleeve 95, and in the process of moving, the limiting slider 97 slides along the inner wall of the limiting slide groove 911, thereby limiting the clamping plate 92, so that the mounting blocks 96 are respectively inserted into the fixing holes on the mounting plate for positioning and fixing, thereby improving the stability of the installation. When adjusting the irradiation angle of the LEC cold light source 5, the ball 12 is rotated along the mounting column 11 and the inside of the semicircular groove 201, and the lamp tube 1 is folded to adjust the angle. After the adjustment is completed, the friction between the semicircular groove 201 and the rubber ball 10 and the anti-skid pad 210 in the mounting column 11 and the outer wall of the ball 12 is increased to improve the stability of the lamp tube 1. When adjusting the irradiation range of the LEC cold light source 5, the two push plates 81 on the outer wall of the sleeve 3 are moved to the left along the arc groove 301 and the spring 83 is squeezed, so that the block 82 is separated from the inside of the fixing groove 7, and then the sleeve 3 drives the lampshade 4 to slide up or down along the connecting groove 6 through the slider 31. When the lampshade 4 is moved down, the irradiation range of the LEC cold light source 5 is more concentrated, and when the lampshade 4 is moved up, the irradiation range of the LEC cold light source 5 is more diffused, and when it is adjusted to a suitable position, the block 82 is rebounded and inserted into the inside of the fixing groove 7 by utilizing the elasticity of the spring 83. Thus, the lampshade 4 is positioned and fixed.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
