[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Embodiment 1

[0019] See also Figure 1-2 A new type of light guide strip with uniform light for LED lamps comprises: a mask 1, a rear shell 2, a light guide strip 3, a side cover L4, a side cover R5, a wiring harness sub-assembly 6, a lamp bead board 1 7 and a lamp bead board 2 8. The LED lamp beads are installed in the rear shell 2, and the driving aluminum substrate is installed in the rear shell 2. The light guide strip 3 is aligned with the center of the LED lamp beads and installed on the rear shell 2. The PC lens is installed on the rear shell 2 and the mask 1 is fixed with glue.

[0020] Preferably, the mask 1 adopts a frame printed with black ink to enhance the overall aesthetics of the product, conceal the ugly glue and shield the internal structure of the lamp, solve the problem of glue overflow, reduce the number of assembly steps, and improve production efficiency.

[0021] Preferably, a lamp bead plate 1 7 and a lamp bead plate 2 8 are respectively installed at both ends of the light guide strip 3 .

[0022] Preferably, a side cover R5 and a side cover L4 are respectively installed at both ends of the rear shell 2.

[0023] Preferably, the side cover R5 is electrically connected to a wiring harness sub-assembly 6 at one end away from the rear shell 2 .

[0024] It should be specifically explained that: the side cover L4 and the side cover R5 are arranged at the two ends of the lamp. The wiring method adopts a terminal line from each of the side covers L4 and R5 at both ends to be directly plugged into the driving aluminum substrate, which solves the problem that the connecting line is too long and easily shakes and causes abnormal noise. The product can be equipped with a multi-angle adjustable lamp mounting bracket. The bracket is locked on the back of the lamp, and the bottom is locked to the body to fix it. The lamp is 180° with the lamp body as the center, which is very convenient to use. The design freedom of the new LED lamp light guide strip with uniform light is relatively high, which can make full use of the space, realize unconventional appearance requirements, and reduce the number of LED lamp beads. The light can achieve the effect of uniform light emission at a lower price, and the new L The light guide strip with uniform ED lamp light is uniform, with good luminous effect and high brightness. Many special optical surfaces are used in the design to process the light. Since there are only two LED lamp beads, the light at both ends is guided to the middle. The distance is too long, so some light guide teeth are needed for each small distance, and the light is reflected to the end point one by one. The light emitted by the LED lamp beads enters the light guide strip 3 from the light input head. Some of the light is totally reflected at the optical pattern of the light input head, and then enters the light guide tooth area. Some of the light does not undergo total reflection at the optical pattern of the light input head, but directly enters the light guide tooth area and merges with the light totally reflected by the light input head. The light together emits the required uniform light under the total reflection of the light guide teeth and enters the light guide strip 3, so that the light output of the light guide strip 3 is uniform and not dazzling.

[0025] It should be specially noted that: the LED lamp beads in a new type of LED light guide strip with uniform light emitter collect and gather the divergent light through the light guide strip 3, so that the light is concentrated, the brightness per unit area is greatly improved, the light is uniform and beautiful, and it reminds the rear-end driving at night that there is a car in front at a close distance, which greatly improves the safety of night driving. The new type of LED light guide strip with uniform light emits uniform light, has a simple structure, high operability, easy control, and low cost, and has practical application value.
