Problems solved by technology

[0008] 2. LED devices of different colors have different operating voltages and operating currents, and the drivers required for LED lights of different colors are also different, which makes the control circuit structure of the lighting system complex, and the cost of LED devices of different primary colors is completely different. High is not suitable for large-scale promotion and use
[0009] 3. The luminous efficiency of red light is low, and high-power LED lamps are required to achieve the light intensity required by poultry. LED lamps generate more heat and need to be quickly dissipated. Higher requirements are placed on the heat dissipation performance and operating costs of lamps.

Embodiment 1

[0033] This embodiment provides a light-emitting device for laying poultry and breeding poultry breeding, which includes a first light-emitting light source and a wavelength conversion medium layer coated on the first light-emitting light source.

[0034] In this embodiment, the first light-emitting light source can be any type of semiconductor-based light source, such as light-emitting diode (LED), high-power LED, organic LED (OLED), inorganic EL and laser diode LED; preferably, the LED can Is any type of LED, such as flip chip type (thin film flip semiconductor chip), patterned sapphire substrate, etc. type.

[0035] The first light source adopts a blue light semiconductor chip, and the blue light semiconductor chip may be a semiconductor light emitting element such as a semiconductor laser, or a solid light emitting element such as an EL element such as an organic EL (Electro Luminescence: electroluminescence). LED may refer to packaged LEDs, unpackaged LEDs, surface mount ...

Embodiment 2

[0051] This embodiment provides a light-emitting device for laying poultry and breeding poultry breeding, which is different from Embodiment 1 in that the first light source and the second light source both emit blue-violet light of 330-420nm The blue-violet light semiconductor chip, and makes the spatial spectral uniformity of the poultry visual organ or the hypothalamus outside the retina U R / B Should not be less than 80%.

[0052] In the spectral distribution emitted by the light-emitting device used for laying poultry and breeding poultry breeding, when the integral value of the wavelength range of 420-730nm is set to 100%, the ratio of the integral value of the wavelength range of 600nm to 730nm is 40% More than % and less than 90%.

[0053] When the integral value in the wavelength range of 330-730 nm is 100%, the ratio of the integral value in the wavelength range of 330 nm-420 nm is 1% or more and 10% or less. Red light and far-red light account for between 50% and 9...

Embodiment 3

[0056] This embodiment provides a lighting device for laying poultry and breeding poultry breeding, which includes the light-emitting device for laying poultry and breeding poultry breeding described in Embodiment 1 and Embodiment 2, and also includes a control working circuit and a control device , the control device is electrically coupled with the light-emitting device through a control working circuit to operate the light-emitting characteristics of the light-emitting device for laying poultry and breeding poultry farming, wherein the control working circuit includes a flicker eliminating unit.

[0057] Specifically, the control device controls the current of the first light emitting source to adjust the spectral radiation flux emitted by the first light emitting source; preferably, the control device may be a remote control device.

[0058] Preferably, the lighting device for laying poultry and breeding poultry breeding also includes a storage device, which pre-stores a gr...

Abstract

The invention discloses a light-emitting device and an illumination device for breeding laying fowls and breeding fowls. The light-emitting device comprises a first light-emitting light source and a wavelength conversion medium layer wrapping the first light-emitting light source, the first light-emitting light source adopts a blue light semiconductor chip, and the wavelength conversion dielectriclayer is a red phosphor. The illumination device for breeding the laying fowls and the breeding fowls is realized by adopting a single-primary-color semiconductor light source, namely the blue-lightsemiconductor chip, so that the uniformity and consistency of light are good. Moreover, the problem that in the prior art, a complex driving circuit structure needs to be designed for a light mixing lamp manufactured by combining blue-light and red-light semiconductors, is solved, the cost is lower, and the light-emitting device and the illumination device are suitable for large-scale popularization.

Description

technical field [0001] The invention relates to a poultry breeding lighting system, in particular to a light emitting device and a lighting device for laying poultry and breeding poultry breeding. Background technique [0002] The researchers found that the bird's eyes have more cone cells with a sensitive area of ​​425nm on the retina than humans, so that the bird's eyes can see the light of 320-400nm, that is, they can see part of the blue-violet light. This means that poultry's perception of light is different from that of humans, and the lighting regime based on human sensory experience is also used in poultry farming. The special visual system of birds determines that their sensitivity to light in the range of 400-480nm and 580-700nm is better than that of humans, that is, under certain light color conditions, the level of illumination perceived by birds is different from that of humans. Both poultry and humans are most sensitive to light at 545-575nm, but because bird...
