Description

[Technical field]

[0001] The present invention relates to a lighting device, and more particularly to a lighting device having a blue light blocking function. [Background technology]

[0002] Some applications, such as semiconductor factories, clean rooms, and biological laboratories, require lighting devices with blue light blocking capabilities. The above applications require lighting devices to have blue light blocking capabilities that filter out light with wavelengths less than 500 nm. In addition, some applications, such as printed circuit board development laboratories and plasma LCD panel factories, require lighting devices to have blue light blocking capabilities that filter out light with wavelengths less than 480 nm.

[0003] However, some existing lighting devices with blue light blocking function need to absorb blue light through inorganic rare earth powder, which reduces the light efficiency of the lighting device and leads to energy waste. In addition, the price of rare earths is relatively high, which increases the cost of lighting equipment.

[0004] In addition, some conventional lighting devices with blue light blocking function need to use filtering gloves to block blue light, which reduces the light efficiency of the lighting device by more than 50%, not only resulting in energy waste but also lowering the color temperature of the lighting device (below 2200K), making it easy for users to feel uncomfortable in their eyes.

[0005] Although China Patent Application Publication No. 107151361, China Patent Application Publication No. 103803795 and US Patent Application Publication No. 20140233243 all disclose technical content related to the components of glove materials, they still fail to effectively solve the problems of the prior art.

For ease of understanding, the same members in the following embodiments will be described with the same reference numerals.

[0022] FIG. 1 is an exploded view of a lighting device with a blue light blocking function according to an embodiment of the present invention. As shown in the figure, the lighting device 1 includes a heat dissipating lamp body 11, a globe 12, a light source substrate 13, and two lamp holders 14. The lighting device 1 may be a portable lighting device such as a flashlight or a handheld searchlight. The lighting device 1 may also be a non-portable lighting device such as a lamp tube or a flat panel lamp.

[0023] The globe 12 may be translucent. The globe 12 is connected to the heat-dissipating lamp body 11, and forms a receiving space between the heat-dissipating lamp body 11 and the globe 12. In one embodiment, the heat-dissipating lamp body 11 is made of a metal material such as iron, copper, aluminum, stainless steel, etc.

[0024] The light source board 13 is disposed on the heat-dissipating lamp body 11 and is located in the receiving space between the globe 12 and the heat-dissipating lamp body 11. The light source board 13 includes a circuit board 131 and a plurality of light sources 132 disposed on the circuit board 131. In this embodiment, the plurality of light sources 132 are (white light) light-emitting diodes (LEDs). In another embodiment, the plurality of light sources 132 are (white light) light-emitting diode arrays or other conventional light sources.

[0025] The two lamp bases 14 mentioned above are respectively disposed on both ends of the heat dissipation lamp body 11. Each lamp holder 14 includes a housing 141 and two metal pins 142 provided on the housing 141. The lighting device 1 can be attached to the lamp holder via the plurality of metal pins 142, and can be connected to an external power source (such as a commercial power source) via the lamp holder.

[0026] The globe 12 can be produced by extrusion molding, and includes polycarbonate, benzidine yellow (benzidine yellow G, molecular formula is CaHbClcNdOe; a, b, c, d, and e represent natural numbers), and a fluorescent exciter (aromatic hydrocarbon organic compound). The mass ratio of the polycarbonate, benzidine yellow, and fluorescent activator is a first value: a second value: a third value. In one embodiment, the first value is 950 to 1050, the second value is 2 to 8, and the third value is 0.1 to 0.8. In another embodiment, the first value is 970 to 1030, the second value is 2.2 to 7, and the third value is 0.3 to 0.7. In another embodiment, the first value is 990 to 1010, the second value is 2.3 to 6, and the third value is 0.4 to 0.6. The fluorescent activator (aromatic hydrocarbon organic) may be a conventional monocyclic aromatic hydrocarbon compound, a polycyclic aromatic hydrocarbon compound, a non-benzene aromatic hydrocarbon compound, etc. Fluorescent activators should be well known to those skilled in the art, and therefore will not be described in detail herein.

[0027] For example, the mass ratio of polycarbonate, benzidine yellow, and fluorescent activator can be 1000:5:0.5. The blue light component in the light emitted by the lighting device 1 having the globe 12 with such a mass ratio can be effectively reduced. Here, after the light emitted by the lighting device 1 passes through the globe 12, the energy ratio of the light with a wavelength of 380 nm to 480 nm is 0.21%, the energy ratio of the light with a wavelength of 380 nm to 500 nm is 0.5%, and the M / P value is 0.353 (M is the energy under the dark visual effect, and P is the energy under the photopic visual effect. The definition of the M / P value refers to WELL Healthy Building Standard V2). The light source 132 (white light emitting diode) includes a blue light chip, and the wavelength of the light emitted by the light source 132 is 380 to 760 nm. Among them, the blue light with a wavelength of 460 nm or less is converted into light with a wavelength of 560 nm or more through the fluorescent activator of the globe 12. In addition, blue light with a wavelength of 460 to 500 nm is converted into light with a wavelength of 500 to 550 nm via benzidine yellow. The M / P value of the lighting device 1 having the globe 12 with the above mass ratio is effectively improved, suppressing melatonin secretion and improving the user's ability to concentrate.

[0028] The lighting device 1 having the globe 12 with the above mass ratio can further reduce the deviation of the color coordinates of the light emitted by the lighting device 1 and prevent a significant drop in the color temperature of the light. The color temperature of the light emitted by the lighting device 1 is 2500K, which can prevent discomfort to the user's eyes.

[0029] For example, the mass ratio of polycarbonate, benzidine yellow, and fluorescent activator can be 1000:2.5:0.5. The blue light component in the light emitted by the lighting device 1 having the globe 12 with the above mass ratio can be effectively reduced. Among them, after the light emitted by the lighting device 1 passes through the globe 12, the energy ratio of the light with a wavelength of 380nm to 480nm is 0.29%, the energy ratio of the light with a wavelength of 380nm to 500nm is 2.36%, and the M / P value is 0.477. The light source 132 (white light emitting diode) includes a blue light chip, and the wavelength of the light emitted by the light source 132 is 380 to 760nm. Among them, the blue light with a wavelength of 460nm or less is converted into the light with a wavelength of 560nm or more through the fluorescent activator of the globe 12. In addition, the blue light with a wavelength of 460nm to 500nm is converted into the light with a wavelength of 500 to 550nm through the benzidine yellow. The M / P value of the lighting device 1 having the globe 12 with the above mass ratio is effectively improved, which can suppress the secretion of melatonin and improve the concentration of the user.

[0030] Similarly, the lighting device 1 having the globe 12 with the above mass ratio can further reduce the deviation of the color coordinates of the light emitted by the lighting device 1 and suppress a significant drop in the color temperature of the light. The color temperature of the light emitted by the lighting device 1 is 3000K, which can prevent discomfort to the user's eyes.

[0031] As can be seen from the above, the globe 12 of the lighting device 1 includes polycarbonate, benzidine yellow and a fluorescent activator, and the mass ratio of these components is the first value: the second value: the third value. The first value is 950-1050, the second value is 2-8, and the third value is 0.1-0.8. The above-mentioned components and their special mass ratios can effectively reduce the blue light component of the light emitted by the lighting device 1. Therefore, the lighting device 1 can meet the requirements of industrial applications. In addition, the above-mentioned components and their special mass ratios can convert a part of the blue light emitted by the blue light chip of the lighting device 1 into light with a wavelength of 480 nm or 500 nm or more without completely removing the blue light. Therefore, the light efficiency of the lighting device 1 is not significantly reduced, the energy utilization rate of the lighting device 1 is improved, and the power consumption of the lighting device 1 is reduced. In addition, the light emitted by the lighting device 1 has an appropriate color temperature and can be made not to cause discomfort to the user's eyes. Therefore, the lighting device 1 can further expand its application range.

[0032] In addition, as mentioned above, the above-mentioned components and their special mass ratios can convert a part of the blue light emitted by the blue light chip of the lighting device 1 into light with a wavelength of 480nm or 500nm or more, thus effectively increasing the green light component of the light emitted by the lighting device 1 and greatly increasing the M / P value of the emitted light, effectively enhancing the user's concentration, so that the user can achieve higher work efficiency.

[0033] Of course, this embodiment is used for illustrative purposes only and does not limit the scope of the present invention, and any equivalent modifications or alterations made based on the lighting device with blue light cutting function of this embodiment should still be included in the patent scope of the present invention.

[0034] 2 is a perspective view of a lighting device with a blue light blocking function according to another embodiment of the present invention. As shown in the figure, the lighting device 2 includes a heat dissipation lamp body 21, a globe 22, and a light source substrate 23. The lighting device 2 can be connected to an external power source (such as a commercial power source) through electrical connection interfaces on both sides.

[0035] The difference with the previous embodiment is that the structure and appearance of the lighting device 2 is different from the lighting device 1 of the previous embodiment, but similar components can still be used.

[0036] Similarly, the globe 22 may include polycarbonate, benzidine yellow, and a fluorescent activator (aromatic hydrocarbon organic material). The mass ratio of the polycarbonate, benzidine yellow, and fluorescent activator is a first value: a second value: a third value. In one embodiment, the first value is 950-1050, the second value is 2-8, and the third value is 0.1-0.8. In another embodiment, the first value is 970-1030, the second value is 2.2-7, and the third value is 0.3-0.7. In another embodiment, the first value is 990-1010, the second value is 2.3-6, and the third value is 0.4-0.6.

[0037] Similarly, the globe 12 of the lighting device 1 includes polycarbonate, benzidine yellow, and a fluorescent activator, and the mass ratio of each of these components is a first value: a second value: a third value. The first value is 950 to 1050, the second value is 2 to 8, and the third value is 0.1 to 0.8. The above-mentioned components and their special mass ratio can effectively reduce the blue light component of the light emitted by the lighting device 1. Therefore, the lighting device 1 can meet the requirements of industrial applications. In addition, the above-mentioned components and their special mass ratio can convert a part of the blue light emitted by the blue light chip of the lighting device 1 into light with a wavelength of 480 nm or 500 nm or more without completely removing the blue light. Therefore, the light efficiency of the lighting device 1 is not significantly reduced, the energy utilization rate of the lighting device 1 is improved, and the power consumption of the lighting device 1 is reduced. Furthermore, the light emitted by the lighting device 1 has an appropriate color temperature and can be made not to cause discomfort to the user's eyes. Therefore, the lighting device 1 can further expand the range of applications.

[0038] In addition, as mentioned above, the above-mentioned components and their special mass ratios can convert a part of the blue light emitted by the blue light chip of the lighting device 1 into light with a wavelength of 480nm or 500nm or more, thus effectively increasing the green light component of the light emitted by the lighting device 1 and greatly increasing the M / P value of the emitted light, effectively enhancing the user's concentration, so that the user can achieve higher work efficiency.

[0039] Of course, this embodiment is used for illustrative purposes only and does not limit the scope of the present invention, and any equivalent modifications or alterations made based on the lighting device with blue light cutting function of this embodiment should still be included in the patent scope of the present invention.

[0040] In addition, some conventional lighting devices with blue light blocking function need to absorb blue light through inorganic rare earth powder, which reduces the light efficiency of the lighting device and leads to energy waste. In addition, the price of rare earth is relatively high, and the cost of the lighting equipment also increases. In addition, some conventional lighting devices with blue light blocking function need to block blue light through a blocking globe, which not only reduces the light efficiency of the lighting device by 50% or more, which leads to energy waste, but also reduces the color temperature of the lighting device (less than 2200K), which is likely to cause discomfort to the eyes of the user. In contrast, according to an embodiment of the present invention, the globe of the lighting device includes polycarbonate, benzidine yellow, and a fluorescent activator, and the mass ratio of these components is a first value: a second value: a third value, where the first value is 950 to 1050, the second value is 2 to 8, and the third value is 0.1 to 0.8. The above-mentioned components and their special mass ratios can effectively reduce the blue light component of the light emitted by the lighting device. Therefore, the lighting device can meet the needs of industrial applications.

[0041] In addition, according to an embodiment of the present invention, the globe of the lighting device includes polycarbonate, benzidine yellow and a fluorescent activator, and the mass ratio of these components has a special design. The above-mentioned components and their special mass ratio can convert a part of the blue light emitted by the blue light chip of the lighting device into light with a wavelength of 480 nm or 500 nm or more, but do not completely block the blue light. Therefore, the light efficiency of the lighting device is not significantly reduced, and the energy utilization rate of the lighting device can be improved and the power consumption of the lighting device can be reduced. Therefore, the lighting device is more energy-saving and can meet the trend of future development.

[0042] In addition, according to an embodiment of the present invention, the globe of the lighting device comprises polycarbonate, benzidine yellow and fluorescent activator, and the mass ratio of these components has a special design. The above-mentioned components and their special mass ratio can not only effectively cut the blue light emitted by the blue light chip of the lighting device, but also make the light emitted by the light source board have a suitable color temperature, so as not to cause discomfort to the eyes of the user. Therefore, the application scope of the lighting device can be further expanded.
