Description

Technical Field

[0001] This utility model relates to an LED lamp bead, specifically a rectangular light spot LED lamp bead. Background Technology

[0002] In the security industry, because camera lenses typically have a 16:9 or other aspect ratio square field of view, using conventional LED chips with a 360-degree conical emission angle necessitates the use of secondary optical lenses to control the beam angle and maximize light utilization in camera lighting. Without these lenses, the circular light emitted by the LEDs contrasts with the rectangular field of view of the lens, resulting in significant light waste. Furthermore, the light transmission of the secondary lens material limits light transmission. To address this issue, the inventors designed a rectangular beam LED chip. This LED chip's horizontal, vertical, and diagonal angles are compatible with most 16:9 4mm lenses on the market, maximizing light utilization. Customers using this chip can eliminate the need for secondary optical lenses. Utility Model Content

[0003] The purpose of this invention is to provide a rectangular light spot LED bead that is simple and reasonably designed. Through optical design, the bulb head of the LED bead is designed to gradually rise from both ends to the middle in a curved shape, so that the refraction angle of the horizontal light of the LED body is between 105° and 125°, and the refraction angle of the vertical light is between 55° and 75°. This meets the field of view of most 16:9 4mm lenses on the market and maximizes the utilization of light, thereby solving the problem that security cameras need to use secondary optical lenses for supplementary lighting.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rectangular light spot LED lamp bead, which includes a base and a light-transmitting cover placed on the base. The upper end face of the base is recessed to form a recessed groove, and an LED lamp body is installed in the recessed groove. The light-transmitting cover is placed on the recessed groove and completely blocks the LED lamp body. The light-transmitting cover includes a cover body and an LED bead ball head and a light-transmitting base integrally formed on the upper and lower end faces of the cover body. The LED bead ball head gradually rises from both ends to the middle in a rectangular curved shape. The light-transmitting base has a light-transmitting groove adapted to the LED lamp body. When the light-transmitting cover is placed on the base, the light-transmitting base abuts against the inner wall of the recessed groove, and the light-transmitting groove covers the LED lamp body and contacts the LED lamp body.

[0005] Preferably, the base is provided with a PCBA board for controlling the operation of the LED lamp body, and the PCBA board is electrically connected to the LED lamp body.

[0006] Preferably, the inner wall of the sinking trough gradually widens from bottom to top, forming a funnel shape.

[0007] Preferably, the light emitted by the LED lamp body is refracted by the lamp bead ball head and refracted to the outside of the lamp bead ball head. The refraction angle of the horizontal light of the LED lamp body is between 105° and 125°, and the refraction angle of the vertical light is between 55° and 75°.

[0008] Preferably, the height of the light-transmitting cover is between 1mm and 5mm, and the light-transmitting cover is made of low-refractive silicone material.

[0009] Preferably, the light-transmitting base forms an angle with the horizontal plane, and the angle value is between 30° and 65°.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a rectangular light spot LED lamp bead, which includes a base and a light-transmitting cover placed on the base. The overall structure is simple and reasonably designed. A recessed groove is formed on the upper end surface of the base, and an LED lamp body is installed in the recessed groove. The light-transmitting cover is placed on the recessed groove and completely blocks the LED lamp body. The light-transmitting cover includes a cover body and LED bead ball heads and light-transmitting bases integrally formed on the upper and lower end surfaces of the cover body. The LED bead ball heads gradually rise from both ends to the middle, forming a rectangular curved surface, so that the refraction angle of the horizontal light of the LED lamp body is between 105° and 125°, and the refraction angle of the vertical light is between 55° and 75°, which meets the field of view of most 16:9 4mm lenses on the market, and at the same time maximizes the light utilization rate, thereby solving the problem that security cameras need to use secondary optical lenses for supplementary lighting.

[0011] 2. This utility model features a recessed groove on the upper surface of the base. The inner wall of the recessed groove gradually widens from bottom to top, forming a funnel shape. The light-transmitting base abuts against the inner wall of the recessed groove, and an angle is formed between the light-transmitting base and the horizontal plane. The angle value of this angle is between 30° and 65°. This design facilitates the assembly of rectangular light spot LED beads. The assembled rectangular light spot LED beads meet the requirements of a horizontal light refraction angle value between 105° and 125° and a vertical light refraction angle value between 55° and 75°, thus meeting the user's needs and demonstrating strong practicality.

[0017] Please see Figures 1 to 4 The present invention provides an embodiment of a rectangular light spot LED bead, which includes a base 1 and a light-transmitting cover 2 covering the base 1. The upper end surface of the base 1 is recessed to form a recessed groove 11. The inner wall of the recessed groove 11 gradually widens from bottom to top, forming a funnel shape. An LED lamp body 12 is installed in the recessed groove 11.

The LED bead ball heads 22 gradually rise from both ends to the middle in a rectangular curved shape. The light-transmitting base 23 has a light-transmitting groove 24 adapted to the LED lamp body 12. When the light-transmitting cover 2 is placed on the base 1, the light-transmitting base 23 abuts against the inner wall of the recessed groove 11, and the light-transmitting groove 24 covers the LED lamp body 12 and contacts the LED lamp body 12.

[0018] Specifically, the base 1 is provided with a PCBA board 13 for controlling the operation of the LED lamp body 12. The PCBA board 13 is electrically connected to the LED lamp body 12. More specifically, the PCBA board 13 is provided with at least a control circuit for controlling the operation of the LED lamp body 12. The control circuit includes a power supply circuit and an LED lamp body 12 brightness control circuit. It should be noted that the power supply circuit and the LED lamp body 12 brightness control circuit are existing technologies and will not be described in detail here. It should be noted that in order to reduce the light spot, the overcurrent capability of the LED lamp body 12 in this utility model is greater than 500mA.

[0019] Specifically, the light emitted by the LED lamp body 12 is refracted by the lamp bead ball head 22 and refracted to the outside of the lamp bead ball head 22.

[0021] Specifically, the light-transmitting base 23 forms an angle with the horizontal plane, and the angle value of the angle is between 30° and 65°. When the light-transmitting base 23 is inserted into the sink 11, it can be integrated with the inner wall of the sink 11 through the angle formed between the light-transmitting base 23 and the horizontal plane, which has good stability and good light transmission of the light emitted by the LED lamp body 12.

[0022] Please see Figure 5 , Figure 5 This is an illuminance distribution diagram of the rectangular spot LED bead of this utility model at a distance of 1 meter. From the diagram, we can see that the rectangular spot LED bead of this utility model diffuses light in a rectangular shape from the inside out, which can maximize the utilization of light. When customers use our rectangular spot LED bead for supplementary lighting, they can eliminate the need for a secondary optical lens, making it highly practical.
