Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a full-spectrum LED lamp. Background Technology

[0002] Traditional LED lights typically rely on mixing light from specific wavelengths to produce white light, a process usually involving the mixing of blue and yellow light. While this method provides sufficient brightness and is relatively inexpensive, it produces a discrete rather than continuous spectrum. In other words, it doesn't cover the entire visible spectrum like sunlight or high-quality incandescent light.

[0003] Due to the lack of certain wavelengths of light, objects under traditional LED lights may not appear as comfortably or naturally as under natural light or higher-quality artificial light sources. Prolonged exposure to such lighting can cause eye strain or other discomfort. Furthermore, because of the missing portions of their spectrum, particularly the red and other long-wavelength regions, they tend to have lower CRI values. This means they perform poorly in displaying color accuracy, especially in applications requiring precise color recognition, such as art galleries, photography studios, or medical environments.

[0004] For the reasons mentioned above, items illuminated by traditional LED lights may exhibit color deviations. For example, a person's skin tone may appear pale or unhealthy, or the color of clothing may look different from how it was actually purchased. These discrepancies not only affect the user experience but can also negatively impact commercial displays and other similar occasions.

[0005] This utility model is based on the above-mentioned circumstances. Utility Model Content

[0006] This invention overcomes the shortcomings of the prior art and provides a full-spectrum LED lamp that closely resembles natural sunlight, has good lighting effect, and a high color rendering index.

[0007] This utility model is achieved through the following technical solution:

[0008] A full-spectrum LED lamp includes a lamp body with heat dissipation fins and an LED light source. The LED light source includes a substrate connected to the lamp body. The substrate has a light-emitting unit composed of multiple LED chips, including ultraviolet LED chips, purple LED chips, blue LED chips, green LED chips, yellow LED chips, red LED chips, and infrared LED chips. The substrate also has positive and negative pins for connecting the light-emitting unit to a power supply.

[0009] The wavelength range of the ultraviolet LED chip is 300-350 nm, the wavelength range of the violet LED chip is 350-400 nm, the wavelength range of the blue LED chip is 420-470 nm, the wavelength range of the green LED chip is 520-540 nm, the wavelength range of the yellow LED chip is 580-600 nm, the wavelength range of the red LED chip is 620-650 nm, and the wavelength range of the infrared LED chip is 750-1000 nm.

[0010] In the full-spectrum LED lamp described above, the LED chips in the light-emitting unit are distributed in a matrix on a substrate.

[0011] In the full-spectrum LED lamp described above, the spacing between two adjacent LED chips is 0.1-20.0 mm.

[0012] As described above, in a full-spectrum LED luminaire, the spacing between every two adjacent LED chips is equal.

[0013] As described above, in a full-spectrum LED lamp, the substrate is further provided with an optical cover for protecting the light-emitting unit or focusing the light.

[0014] As described above, in a full-spectrum LED lamp, the lamp body and the heat sink fins are an integral structure.

[0015] In the full-spectrum LED lamp described above, the positive and negative pins are connected with wires for connecting to a power source.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] This luminaire utilizes a combination of LED chips with different wavelengths from ultraviolet to infrared, enabling it to produce a nearly continuous spectrum. This means it more closely resembles natural daylight, providing a more realistic lighting effect, meeting the requirements of high-quality lighting applications such as museums, galleries, photography studios, and medical settings. Full-spectrum luminaires typically have a higher Color Rendering Index (CRI), accurately reproducing the true colors of objects. This is highly advantageous for commercial displays, art exhibitions, and any scenario with stringent color accuracy requirements. Compared to traditional LED luminaires, full-spectrum LED luminaires provide softer and more uniform light, reducing the risk of eye fatigue and improving comfort during extended use. Despite incorporating multiple LED chips, LED technology itself is known for its high energy efficiency. Therefore, even with a multi-chip configuration, this luminaire maintains relatively low energy consumption while providing excellent lighting performance. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1 to 3 The illustrated full-spectrum LED lamp includes a lamp body 10, on which heat dissipation fins 11 and an LED light source are provided. The LED light source includes a substrate 1 connected to the lamp body 10. The substrate 1 is provided with a conductive circuit and a light-emitting unit 2 composed of multiple LED chips. The conductive circuit is connected to the light-emitting unit 2. The LED chips include ultraviolet LED chip 21, violet LED chip 22, blue LED chip 23, green LED chip 24, yellow LED chip 25, red LED chip 26, and infrared LED chip 27. The substrate 1 is also provided with positive and negative pins 3 for connecting the light-emitting unit 2 to a power supply. The positive and negative pins 3 are connected with wires 5 for connecting to a power supply 6.

[0024] This luminaire utilizes a combination of LED chips with different wavelengths from ultraviolet to infrared, enabling it to produce a nearly continuous spectrum. This means it more closely resembles natural daylight, providing a more realistic lighting effect, meeting the requirements of high-quality lighting applications such as museums, galleries, photography studios, and medical settings. Full-spectrum luminaires typically have a higher Color Rendering Index (CRI), accurately reproducing the true colors of objects. This is highly advantageous for commercial displays, art exhibitions, and any scenario with stringent color accuracy requirements. Compared to traditional LED luminaires, full-spectrum LED luminaires provide softer and more uniform light, reducing the risk of eye fatigue and improving comfort during extended use. Despite incorporating multiple LED chips, LED technology itself is known for its high energy efficiency. Therefore, even with a multi-chip configuration, this luminaire maintains relatively low energy consumption while providing excellent lighting performance.

[0025] Specifically, the wavelength range of the ultraviolet LED chip 21 is 300-350 nm, the wavelength range of the violet LED chip 22 is 350-400 nm, the wavelength range of the blue LED chip 23 is 420-470 nm, the wavelength range of the green LED chip 24 is 520-540 nm, the wavelength range of the yellow LED chip 25 is 580-600 nm, the wavelength range of the red LED chip 26 is 620-650 nm, and the wavelength range of the infrared LED chip 27 is 750-1000 nm.

[0026] In one embodiment, the LED chips in the light-emitting unit 2 are arranged in a matrix on the substrate 1. This matrix layout ensures that light emitted from each LED chip more evenly covers the target area, reducing potential bright spots or dark areas. This uniformity is particularly important for applications requiring high lighting quality, such as museums, galleries, and professional photography studios. The matrix arrangement allows for the integration of more LED chips within a limited substrate area, thus improving overall space utilization. With a reasonable matrix spacing arrangement, there is sufficient space between each LED chip for heat dissipation, which helps reduce operating temperature, extend LED lifespan, and maintain the stability of its optical performance. Good heat management also reduces the impact of thermal stress on electronic components, improving system reliability. The matrix layout simplifies the design of the driving circuit through row and column addressing. A smaller number of pins are needed to control a large number of LED chips, reducing wiring complexity and manufacturing costs.

[0027] Furthermore, the spacing between two adjacent LED chips is 0.1-20.0 mm.

[0028] Furthermore, the spacing between any two adjacent LED chips is equal. This uniform spacing ensures that the light emitted by each LED chip diffuses and mixes in a similar manner, resulting in a more consistent and smooth light distribution throughout the illuminated area. This helps reduce uneven brightness, shadows, and speckles.

[0029] In one embodiment, LED chips of the same color are arranged alternately, with the chips evenly distributed to ensure that at least one chip of a different color separates any two LED chips of the same color. Of course, to ensure a good mixing effect, some LED chips of the same color can also be arranged adjacent to each other.

[0030] In one embodiment, the substrate 1 is further provided with an optical cover 4 for protecting the light-emitting unit 2 or focusing the light. The optical cover 4 provides a direct physical barrier for the light-emitting unit 2, preventing dust, moisture, particulate matter, and other external contaminants from entering, thereby extending the lifespan of the LED chip and its connecting lines. This is particularly important for lighting fixtures used in outdoor or industrial environments. The protective cover can prevent damage or short-circuit risks caused by accidental contact, especially when used in public places or high-traffic areas, effectively avoiding damage caused by external impacts or improper operation. Furthermore, the optical cover 4 can be configured in a trumpet shape, with a reflective coating applied to the inner wall of the optical cover 4 to achieve a focusing effect.

[0031] In one embodiment, the substrate 1 is connected to the lamp body 10 by threaded fasteners or other connection methods such as glue, and the optical cover 4 is connected to the substrate 1 by other connection methods such as glue or clips.

[0032] In one embodiment, the lamp body 10 and the heat sink fins 11 are an integral structure. This ensures that heat can be transferred more quickly and evenly from the LED light source to the heat sink fins 11, thereby improving the overall heat dissipation efficiency. This helps maintain the operating temperature of the LED chip within the optimal range, extending its lifespan. Compared to a separate design, the integrated structure reduces the contact thermal resistance between different components, allowing heat to dissipate more smoothly and avoiding localized overheating. Reduced production costs: The integrated design reduces the number of parts and assembly steps, lowering manufacturing complexity and labor costs, while also reducing quality problems caused by assembly errors. By combining the lamp body 10 and the heat sink fins 11 into a single unit, the mechanical strength of the lamp is significantly improved, enabling it to better withstand external impacts and vibrations, especially when used in outdoor or industrial environments.
