Description

Technical Field

[0001] This application relates to the field of lighting fixture technology, and specifically discloses a light guide lamp structure with good uniformity. Background Technology

[0002] In automotive lighting, there is a light guide scheme that uses total internal reflection of light within a light guide strip to reflect the light off the side of the light guide strip, thereby illuminating the designated light-emitting area of ​​the lamp.

[0003] In existing technology, the optical principle of light guide strips involves setting a reflective structure on the sidewall, causing light to refract upon contact with the reflective structure, and ultimately the light reaches the human eye from the refracted area. If the light guide strip itself contains other structures besides refraction, these other structures will also refract the light. After continuous refraction, some light may reach the human eye. Because these other structures are inconsistent with the reflective structure, two types of light will be formed: one is the refracted light from the reflective structure, and the other is the refracted light from the other structures. These two types of light will cause uneven light distribution within the field of vision, which is an abrupt defect.

[0004] However, the light guide strip needs to be installed and fixed to prevent it from breaking or making abnormal noises due to vibration during vehicle operation. Therefore, in the existing technology, the light guide strip must have an installation structure. If the light guide strip has other structures, bright spots will inevitably form, causing uneven light within the field of view.

[0005] This invention provides a light guide lamp structure with good uniformity to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that in traditional light guide lamps, the presence of other structures on the light guide strip inevitably creates bright spots, resulting in uneven light distribution within the field of view.

[0007] To achieve the above objectives, the basic solution of this utility model provides a light guide lamp structure with good uniformity, comprising: Light guide strip; The assembly carrier is equipped with a support plate for supporting the bottom of the light guide strip; The bracket is detachably connected to the support plate and is used to press the light guide strip with the support plate. An internal reflector, mounted on the assembly carrier, serves as an auxiliary optical component for the light guide to eliminate stray light. The light source module is mounted on the assembly carrier and is used to guide the light strip to emit light. External decorative parts, located on the assembly carrier, are used to help the assembly carrier wrap the light guide strip, transparent bracket, internal reflector and light source module into a sealed environment. They have light-emitting slots to expose the light-emitting area of ​​the light guide strip separately.

[0008] Furthermore, the bracket is specifically a transparent bracket.

[0009] Furthermore, the bracket and the support plate are connected by screws.

[0010] Furthermore, the bracket has an arc-shaped surface on the side facing the light guide strip that fits against the wall of the light guide strip.

[0011] Furthermore, the bracket is provided with a claw-shaped part for engaging the light guide strip with the support plate, and the claw-shaped part and the arc-shaped surface adopt a smooth transition that fits the wall of the light guide strip.

[0012] Furthermore, the internal space of the bracket is hollowed out.

[0013] Furthermore, the top of the support plate is formed with a guide rib, and the bracket is provided with a groove for accommodating the guide rib.

[0014] The principle and effect of this solution are as follows: 1. Compared with the prior art, this utility model uses a transparent bracket to fix the light guide strip, which effectively avoids the light from hitting the mounting structure due to the long mounting structure of the light guide strip body, and the light hitting the mounting structure is refracted into the human eye, thus causing defects. It solves the problem that the light guide strip of traditional light guide lamps has other structures, which will inevitably form bright spots and cause uneven light in the field of vision.

[0015] 2. Compared with the prior art, the transparent bracket of this utility model serves as an external support and will not affect the normal use of the light guide strip. Furthermore, the transparent bracket will not damage the reflection of light inside the light guide strip, nor will it block the light guide strip. Attached Figure Description

[0020] A light guide lamp structure with good uniformity, implemented as follows: Figure 1 , Figure 2 and Figure 3 As shown: It includes the assembly carrier 1, light guide strip 2, bracket 3, internal reflector, light source module and external decorative parts.

[0021] The external decorative component is secured to the assembly carrier 1 by clips. The assembly carrier 1 and the external decorative component enclose the light guide strip 2, the transparent bracket 3, the internal reflector, and the light source module in a sealed environment. Studs 4 are formed on the assembly carrier 1 to connect to the external structure. A light-emitting groove is opened on the external decorative component to expose the light-emitting area of ​​the light guide strip 2 separately.

[0022] In this embodiment, light source modules are respectively installed at both ends of the assembly carrier 1. The light source modules use LEDs as light sources, and the circuit board controlling the LEDs is fixedly installed with the heat sink. The end of the light guide strip 2 abuts against the circuit board and is illuminated by the LED light.

[0023] A support plate 5 for supporting the bottom of the light guide strip 2 is also formed within the assembly carrier 1. The support plate 5 has a fitting part that helps to adhere to the wall surface of the light guide strip 2. The bracket 3 is connected to the support plate 5 by screws and cooperates with the support plate 5 to press the light guide strip 2. In this embodiment, the bracket 3 is specifically a transparent, purple transparent bracket 3, and the transparent bracket 3 has an arc-shaped surface that adheres to the wall surface of the light guide strip 2 on the side facing the light guide strip 2.
