Description

Technical Field

[0001] This utility model belongs to the field of lighting source technology, specifically relating to a combined stepped LED light source. Background Technology

[0002] LED light sources have advantages such as high luminous efficiency, energy saving, and long lifespan, leading to their increasingly widespread application. However, the installation structure of multi-angle LED light sources is typically complex and cannot be easily assembled. For example, existing technology discloses a combined light source for visual inspection, including a support carrier and several luminaires. The support carrier has a through-hole detection hole and a mounting part located at one end of the detection hole; the luminaires emit linear light and are supported on the support carrier by mounting parts that guide the angle adjustment of the luminaires; several luminaires are distributed at intervals around the center of the detection hole. This method of assembling the light source assembly is complex, and after the light source angle is adjusted, it tends to diffuse in all directions, failing to guarantee the uniformity of the light. Utility Model Content

[0003] To address the problems of complex installation structure and uneven light emission in existing LED light sources, this invention provides a combined stepped LED light source. The LED light source includes multiple stepped light sources arranged in a stepped manner, each composed of three sets of stepped LED beads. After illumination, the light source can clearly and effectively present product features under the camera, highlighting the details of the tested parts of the product. It has a good recognition effect on blurred edges and areas where colors are difficult to distinguish, forming good contrast and improving the efficiency and accuracy of the inspection work.

[0004] This utility model is achieved through the following technical solution:

[0005] A combined stepped LED light source includes a light box 3, which is generally shaped like a quadrangular pyramid with a connecting plate 1 at the bottom. Multiple stepped light sources 5 are arranged sequentially along the inner side of the light box 3, with the lengths of the multiple stepped light sources 5 arranged on the same inner side decreasing sequentially. Each stepped light source 5 includes a fixing column 31, a lampshade 32, a stepped lamp holder 33, LED beads 34, and a lamp base 35. The lampshade 32 is connected to the lamp base 35 to form an internal hollow structure for placing the stepped lamp holder 33. The stepped lamp holder 33 is fixedly connected to the lamp base 35. The stepped lamp holder 33 is in the shape of a three-step staircase, with multiple LED beads 34 arranged on each step surface. Each LED bead 34 can be controlled individually. The multiple LED beads 34 that make up the stepped light source 5 are evenly distributed at different heights within the light box 3, thereby achieving illumination at different angles.

[0006] Furthermore, four stepped light sources 5 are provided along each inner side of the light box 3.

[0007] Furthermore, the two ends of the stepped light source 5 are fixed to the inner side of the lamp box 3 by the light source bracket 4.

[0008] Furthermore, the light source bracket 4 is an L-shaped thin sheet with threaded holes on its short side, which is fixedly connected to the inner side of the lamp box 3 by bolts. The long side of the L-shaped thin sheet has holes, which are fixedly connected to both ends of the stepped light source 5 by bolts.

[0009] Furthermore, the center of the contact plate 1 is provided with an adapter hole 2, which is used to connect to the testing equipment.

[0010] Furthermore, one side of the inner side of the contact plate 1 is a reflective surface, on which are respectively opened a lamp box mounting hole 22 for connecting the lamp box and a fixing hole 21 for connecting the detection system.

[0011] Furthermore, the light box 3 is a hollow shell structure with open top and bottom, and its inner sides are reflective surfaces.

[0012] Furthermore, each end face of the lampshade 32 is provided with a fixing post 31, which is used to connect with the light source bracket 4.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] This utility model discloses a combined stepped LED light source. By arranging LED beads in a stepped manner, it achieves different depths of light emission from a single light source. The stepped light source presents a uniform height distribution within the light box, thus achieving illumination at different angles. The combination of these two structures achieves illumination at different angles and depths in a simple way. The interior of the light box is designed with a reflective surface to constrain light divergence, ensuring that the light is emitted uniformly in one direction. This combined stepped LED light source can fix the light source board without the need for other auxiliary fixing parts or complex fixing methods, offering advantages such as high assembly efficiency and simple structure.

The light box 3 is generally pyramidal in shape, with a connecting plate 1 at the bottom. Multiple stepped light sources 5 are sequentially arranged along the inner side of the light box 3, and the lengths of the multiple stepped light sources 5 arranged on the same inner side decrease sequentially. Figure 3As shown, the stepped light source 5 is generally elongated and includes a fixed column 31, a lampshade 32, a stepped lamp holder 33, LED beads 34, and a lamp base 35. The lampshade 32 is connected to the lamp base 35 to form an internal hollow structure for placing the stepped lamp holder 33. The stepped lamp holder 33 is fixedly connected to the lamp base 35. The stepped lamp holder 33 is made of heat dissipation material and contains a control circuit and a power supply module. A power interface is provided at the bottom and connected to a hole on the lamp base 35, from which the light source is powered. The stepped lamp holder 33 is in the shape of a three-step staircase. Multiple LED beads 34 are provided on each step surface. Each LED bead 34 can be controlled individually by the control circuit. The multiple LED beads 34 that make up the stepped light source 5 are evenly distributed at different heights in the lamp box 3, thereby achieving illumination at different angles.

[0025] Four stepped light sources 5 are provided on each inner side of the light box 3.

[0026] The two ends of the stepped light source 5 are fixed to the inner side of the light box 3 by the light source bracket 4.
