Description
Technical field
The utility model belongs to the side entering type plant light source of plant light sources technical field more particularly to a kind of no light guide plate.
Background technique
The rise for being increasingly reduced to plant factor of population sharply increased with cultivated area provides condition, plant factor
The production system for the Sustainable Development of Modern Agriculture made using high-tech, by control environment for example temperature, humidity, illumination,
The proportion of inorganic matter and organic matter provides necessary condition for plant growth, to reach shortening plant growing cycle, improves
The purpose of production efficiency is the direction of the future of agriculture development.Light environment is one of key element of plant growth, can be direct
Plant growth and development process and chemical substance accumulation are influenced, in addition, illumination is also all the more extensive in the application of plant fresh-keeping aspect, this makes
Obtaining plant illumination becomes one of research hotspot, correspondingly, the plant illumination light source of exploitation function admirable is particularly important.LED
As the third generation lighting source that recent years rises, there are three advantages on plant illumination.First, plant carries out photosynthetic work
It is mainly that the blood orange light that wavelength is 610-720nm and the blue violet light that wavelength is 400-510nm, LED can be sent out with the light of absorption
Monochromatic light spectrum required for plant out;Second, LED light spectrum has adjustability, can be according to different plants in different growth steps
Demand of the section to light, adjusts the light quality ratio of LED, obtains complex spectrum, realizes precisely to light;Third, LED is small in size, energy conservation, light
Electrotransformation is high-efficient, can improve space utilization rate with compact arrangement.
Had already appeared a plurality of types of LED plant light sources in the market, but existing LED plant lamp have it is certain
Red blue lamp pearl is carried out simple array arrangement as in plant illumination lamps and lanterns by defect, but without carrying out secondary optical design,
Since light does not have enough distances to be coupled, low illumination uniformity will lead to short distance area of illumination and red blue light spot occurs, lead
Cause the growth luminous environment with a batch of plant different, the growth cycle and quality of plant just have larger difference.In order to enable
Illumination uniformity is more preferable, and light guide plate can be added in side entering type plant light source in lamps and lanterns, to keep light multiple inside light guide plate
The purpose of uniform in light emission is reflected up to, however the light guide plate in the more uniform lamps and lanterns of illumination is often more thick and heavy, and due to
Light is absorbed in light guide plate, causes light extraction efficiency low, and lamps and lanterns are more heavy, and cost is high.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of side entering type plant light source of high no light guide plate of light extraction efficiency,
It, which also feels, simple structure, lightweight, brightness height, uniform in light emission.
A kind of side entering type plant light source of no light guide plate, including shell, diffuser plate, combination reflective structure, LED light, unrestrained light

Cup.Using this structure, after the light of LED light transmitting carries out the scattering of multi-angle by composite parabolic reflector, reflected light graze
To diffuser plate to project lamps and lanterns, only sub-fraction reflexes to unrestrained light reflecting board and is absorbed by unrestrained light reflecting board, therefore big portion
Graze is divided to diffuser plate, so that emergent light is uniformly mixed, and light efficiency is high, brightness is high.
Preferably, combination reflective structure further includes reflector, reflector in a tubular form, the diameter and composite parabolic of reflector
The diameter of the opening of reflector is identical.Using this structure, since the pipeline of reflection lengthens, the distance of reflection is lengthened, low-angle
Light is also reflected onto diffuser plate, therefore less light reflexes to unrestrained light reflecting board, and more light reflex to diffuser plate, thus light
Effect is higher, brightness is higher.
Preferably, reflective structure is combined Open Side Down inclination.Using this structure, tilted since Open Side Down, it is originally anti-
The light reflective structure that is combined for being incident upon unrestrained light reflecting board blocks, and less light reflexes to unrestrained light reflecting board, and more light reflex to
Diffuser plate, so that light efficiency is higher, brightness is higher.
Preferably, the upper and lower surface of diffuser plate all has several continuous prisms, and the bottom edge side length of the prism of upper surface
The bottom edge side length of the prism of lower surface is small, and the height of the prism of the upper and lower surfaces of diffuser plate is consistent.Using this structure, avoid
Serious Fresnel reflection phenomenon is generated due to graze, promotes light emission effect, light efficiency, brightness.
Preferably, prism is regular triangular prism.Using this structure, the light reflection of graze to diffuser plate is less, and emergent light is more,
Light efficiency is high.
Preferably, diffuser plate is made of PMMA material.Using this structure, material is light, heat-resisting durable.
Preferably, LED light includes red LED lamp and blue LED lamp, red LED lamp and blue LED lamp cross arrangement, and
The distance between adjacent two lamp is identical.Using this structure, red blue-light source cross-distribution be conducive to light be superimposed on light-emitting surface it is mixed
It closes, makes lamps and lanterns light-out effect more evenly.
Preferably, unrestrained light reflecting board includes plate body and diffusive reflective film, and diffusive reflective film is pasted on plate body inner wall.Using this knot
Structure, production is simple, and diffusing reflection effect is good.
The utility model has the beneficial effects that the utility model is by being installed on composite parabolic reflector, LED for LED light
After the light of lamp transmitting carries out the scattering of multi-angle by composite parabolic reflector, reflected light graze to diffuser plate is to project lamp
Tool, and in the reflector of composite parabolic reflector side adapter tube shape, and then it is anti-that script sub-fraction can be made to reflex to unrestrained light
Penetrating the low-angle light of plate, also graze is to diffuser plate, therefore most light grazes arrive diffuser plate, so that emergent light mixes more evenly,
And light efficiency is high, brightness is high;The upper and lower surface of diffuser plate in the utility model all has several continuous prisms, therefore energy
It avoids generating serious Fresnel reflection phenomenon due to graze, to promote light emission effect, light efficiency, brightness;This reality
It include red LED lamp and blue LED lamp with novel middle LED light, red LED lamp and blue LED lamp cross arrangement, and adjacent two lamp
The distance between it is identical, be superimposed mixing on light-emitting surface since red blue-light source cross-distribution is conducive to light, go out lamps and lanterns
Light effect is more evenly.
