Description

Technical Field

[0001] The utility model relates to the technical field of lamp beads, in particular to a focusing SMD lamp bead. Background Art

[0002] LEDs are widely used, with different types of LED products being employed in diverse industries, including signal indicators, displays, backlights, and lighting. SMD lamp beads, with their advantages of high brightness, wide viewing angles, and excellent flatness and consistency, are increasingly being used in LED display screens. Their luminescence principle is to pass current through a compound semiconductor, releasing excess energy as light, thus achieving the desired luminous effect.

[0003] Conventional SMD lamp beads are mainly composed of lamp bead holders and lamp bead chips, and conventional lamp bead chips are welded and fixed on the surface of the lamp bead holder. Although it can meet the lighting needs, the large luminous angle causes light dispersion, making it difficult to achieve centralized lighting, and its focusing effect is poor. In actual application, since the lamp bead chip is on the surface of the lamp bead holder, it is also easy to break, affecting the service life of the SMD lamp beads. Utility Model Content

[0004] In order to solve the technical problem that the current SMD lamp beads have a poor focusing effect due to a large light-emitting angle and scattered light, the utility model proposes a focusing SMD lamp bead.

[0005] The utility model is realized by the following technical solutions:

[0006] A focusing SMD lamp bead comprises a lamp bead holder and a light-emitting chip. The lamp bead holder is provided with a concave cavity for improving the focusing effect. The ratio between the depth of the concave cavity and the height of the lamp bead holder is 0.84-0.89.

[0007] In the above-mentioned focusing SMD lamp bead, the height of the lamp bead bracket is 1.2 mm - 1.7 mm.

[0008] In the above-mentioned focusing SMD lamp bead, the inner wall side of the concave cavity is provided with a reflective surface for increasing the number of light reflections, and the angle between the reflective surface and the bottom wall of the concave cavity is 90°-110°.

[0009] In the above-mentioned focusing SMD lamp bead, the depth of the concave cavity is greater than the thickness of the light-emitting chip, so that the light-emitting angle of the SMD lamp bead light is narrowed.

[0010] In the above-mentioned focusing SMD lamp bead, the concave cavity is in the shape of a truncated cone with a large radius at one end and a small radius at the other end.

[0011] In the above-mentioned focusing SMD lamp bead, a plurality of light-emitting chips are mounted on the bottom wall of the concave cavity.

[0012] In the above-mentioned focusing SMD lamp bead, the cup mouth of the lamp bead bracket is circular.

[0013] In the above-mentioned focusing SMD lamp bead, the reflecting surface is a smooth surface.

[0014] In the above-mentioned focusing SMD lamp bead, the material of the lamp bead bracket is a high-brightness whitening plastic material.

[0015] As described above, in a focusing SMD lamp bead, the lamp bead bracket is provided with a bottom bracket, and oblique arms are provided on both sides of the lamp bead bracket. The bottom bracket and the oblique arms on both sides form the concave cavity.

[0016] Compared with the existing technology, the light-concentrating SMD lamp bead proposed in this utility model has the following beneficial effects:

[0017] 1. The light-concentrating SMD lamp of this utility model includes a lamp holder and a light-emitting chip. The lamp holder has a concave cavity, with the ratio of the cavity's depth to the lamp holder's height being 0.84-0.89. The deeper cavity narrows the beam angle, concentrating the light within the cavity, reducing the beam angle and improving light focusing. The deeper cavity also reduces light scattering, allowing more light to be effectively utilized, improving lighting efficiency. Furthermore, the lamp holder with the concave cavity has a certain degree of pressure resistance, preventing damage to the light-emitting chip and extending the lifespan of the SMD lamp.

[0018] 2. The inner wall of the concave cavity of the present invention is provided with a reflective surface for increasing the number of light reflections. The angle between the reflective surface and the bottom wall of the concave cavity is 90°-110°. Compared with conventional SMD lamp beads, the reflective surface provided on the inner wall of the concave cavity allows light to be reflected more than three times within the concave cavity, which helps to improve the concentration of light. The angle between the reflective surface and the bottom wall is 90°-110°, which helps to reduce light scattering, improve the light reflection effect, and thus improve the light focusing effect.

[0019] 3. The concave cavity of this utility model is truncated in the shape of a cone, with a larger radius at one end and a smaller radius at the other. This cone-shaped cavity helps effectively control the beam angle, achieving a narrower beam angle, directing light more concentratedly forward and improving light-gathering capability. It also helps reduce light scattering during reflection, allowing light to propagate in a predetermined direction, improving lighting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The ratio between the depth of the concave cavity 10 and the height of the lamp holder 1 is 0.84-0.89. The deeper concave cavity 10 of the SMD lamp narrows the beam angle, concentrating the light within the cavity 10, reducing the beam angle and improving the focusing ability. The deeper cavity 10 also reduces light scattering, allowing more light to be effectively utilized and improving lighting efficiency. The lamp holder 1 with the concave cavity 10 also has a certain degree of pressure resistance, which can prevent damage to the SMD lamp and extend its service life.

[0026] Furthermore, as a preferred embodiment of the present invention but not a limitation, the height of the lamp bead bracket 1 is 1.2 mm - 1.7 mm, and the depth of the concave cavity 10 is calculated to be 1 mm - 1.5 mm. Preferably, the depth of the concave cavity is 1.25 mm.

[0027] In this embodiment, the deeper concave cavity can narrow the light beam angle, concentrate the light in the concave cavity, reduce the light-emitting angle, and improve the focusing ability; at the same time, the deeper concave cavity can increase the number of light reflections, so that more light can be effectively utilized, reduce light scattering, and improve lighting efficiency.

[0028] Furthermore, as a preferred embodiment of the present invention but not a limitation, the lamp bead bracket 1 is provided with a bottom bracket 11, oblique arms 12 are provided on both sides of the lamp bead bracket 1, a platform 13 is provided on the top of the oblique arms 12, and the bottom bracket 11 and the oblique arms 12 on both sides enclose the concave cavity 10.

[0029] Furthermore, as a preferred embodiment of the present invention but not a limitation, the inner wall side of the concave cavity 10 is provided with a reflective surface 101 for increasing the number of light reflections, the angle between the reflective surface 101 and the bottom wall of the concave cavity 10 is 90°-110°, the reflective surface 101 is a smooth surface, and the concave cavity 10 is in the shape of a truncated cone with a large radius at one end and a small radius at the other end.

[0030] In this embodiment, the reflective surface provided on the side of the inner wall of the concave cavity enables light to be reflected more than three times in the concave cavity compared to conventional SMD lamp beads, which helps to improve the concentration of light. The angle between the reflective surface and the bottom wall is 90°-110°, which helps to reduce light scattering and improve the light reflection effect, thereby improving the light focusing effect.

[0031] The truncated cone-shaped concave cavity helps to effectively control the beam angle, achieve a narrower beam angle, and direct the light more concentratedly to the front, thereby improving the light-gathering ability; the truncated cone-shaped concave cavity also helps to reduce the scattering of light during the reflection process, allowing the light to propagate in a predetermined direction, thereby improving lighting efficiency.

[0032] Furthermore, as a preferred embodiment of the present invention but not limitation, the cup mouth of the lamp bead holder 1 is circular, and the material of the lamp bead holder 1 is a high-brightness whitening plastic material.

[0033] In this embodiment, the lamp bead holder with a circular cup mouth helps to concentrate the light into the concave cavity, forming a relatively concentrated light beam, further improving the focusing effect; the lamp bead holder with a circular cup mouth also helps to reduce the side scattered light and improve the lighting efficiency; at the same time, the high-brightness and whitening lamp bead holder helps to reduce the absorption of light inside the holder and improve the reflection efficiency of light.

[0034] Furthermore, as a preferred embodiment of the present invention but not a limitation, the light-emitting chip 2 is installed on the bottom wall of the concave cavity 10. A plurality of light-emitting chips 2 can be installed. The light-emitting chip 2 can be a white light wick, a yellow light wick, a red light wick or a wick of other light colors. Preferably, the light-emitting chip 2 is a white light wick.

[0035] In this embodiment, a plurality of lamp beads can be installed on the bottom wall of the concave cavity. The combination of the plurality of lamp beads can improve the lighting brightness of the LED lamp. At the same time, lamp beads of different colors can also be installed in combination to achieve color mixing and a color rendering effect.

[0036] The working principle of this embodiment is as follows:

The lamp bead holder 1 is provided with a concave cavity 10 for improving the focusing effect. A plurality of light-emitting chips 2 are provided on the bottom wall of the concave cavity 10. When the light-emitting chip 2 emits light, since the depth of the concave cavity 10 is greater than the thickness of the light-emitting chip 2, the beam angle of the lamp bead light is narrowed, the light is concentrated in the concave cavity, the light-emitting angle is reduced, and the focusing ability is improved; the light of the light-emitting chip 2 can increase the number of reflections of the light through the reflective surface of the inner wall of the concave cavity, thereby improving the concentration of the light; at the same time, the lamp bead holder 1 with a circular cup mouth and the concave cavity 10 in a truncated cone shape help to reduce the scattering of light during the reflection process, help to improve the concentration of light, and further improve the focusing ability of the SMD lamp bead.
