Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an LED light-emitting device for lighting fresh meat in supermarkets. By simulating the spectrum of fluorescent lamps traditionally used for lighting fresh meat in supermarkets, the LED light-emitting device makes the lamps produced by it illuminate fresh meat. The visual effect for people is basically the same as that of traditional fluorescent lamps, avoiding the problem of mercury pollution, and the LED lighting device has the advantages of higher efficiency and longer life than the original fluorescent lamps

Embodiment 1

[0033] In this embodiment, a single package realizes the LED spectrum of the solution of the present invention.

[0034] The package device of this embodiment is an LED packaging bracket sold on the market, and its structure is as follows: image 3 As shown, it includes LED chip 1 and LED chip 2, packaging substrate 3 and two electrodes 4, the two LED chips are connected in series, the two electrodes are respectively at both ends of the packaging substrate 3, and one of the electrodes is directly connected to the substrate As a whole, it is used to lead out the positive pole of the LED chip 2 and the negative pole of the LED chip 1 .

[0035] In this embodiment, a blue LED chip 1 with a luminous peak wavelength of 450nm-460nm and a red LED chip 2 with a luminous peak wavelength of 600nm-620nm are selected, and the two chips are used in series with a total power of about 0.2W.

[0036] The phosphor used in this embodiment:

[0037] The phosphor composition formula is: β-SiAlO...

Embodiment 2

[0044] In this implementation mode, two packages are used to realize the LED spectrum of the solution of the present invention through light mixing.

[0045] The two packages in this embodiment: one of them realizes the first spectral characteristic and the second spectral characteristic; the other realizes the third spectral characteristic. The light emitted from the two packages is mixed to obtain the LED spectrum of the solution of the present invention.

[0046] The package device of this embodiment adopts the same support structure as that of the first embodiment.

[0047] The first package is made as follows:

[0048] Select a blue LED chip with a luminous peak wavelength of 450nm-460nm, fix the chip on the packaging substrate, and connect the two electrodes of the chip through the two pole pieces at the bottom of the gold wire substrate to conduct with the two electrodes.

[0049]The selected phosphor has the composition formula: β-SiAlON:Eu, the peak wavelength of th...

Abstract

The invention discloses an LED light-emitting device for illuminating fresh meat in supermarkets, and the device comprises at least two light-emitting diodes (LEDs), wherein the emission spectrum of the device comprises an emission peak which is generated by one LED and within the wavelength range of 400-500 nm, an emission peak which is generated by enabling the LED to excite fluorescent powder and within the wavelength range of 500-600 nm and an emission peak which is generated by the other LED and within the wavelength range of 600-630 nm. The LED light-emitting device is consistent with atraditional fluorescent lamp for irradiating fresh meat in color temperature and visual effect, can be used for replacing a fluorescent lamp, avoids the problem of mercury pollution, and is higher inlight efficiency and longer in service life than an original fluorescent lamp.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to an LED lighting device for realizing a special illumination effect on fresh meat in a supermarket. Background technique [0002] In the field of traditional supermarket fresh meat lighting, fluorescent tubes are usually used, but traditional fluorescent lamps have many disadvantages: first, they consume relatively high power and are not energy-saving; second, they contain toxic elements such as mercury, which are not environmentally friendly; third, they are poor in stability. Short life. Although fluorescent lamps have many disadvantages, over the years, people have used fluorescent lamps for special lighting such as fresh meat in supermarkets for a long time, and have become accustomed to their illumination effects and visual aesthetics. [0003] GaN-based light-emitting diode (Light-Emitting Diode) has the advantages of energy saving, high luminous efficiency, no polluti...
