Description

For LED encapsulation structure and the plant illumination device of plant illumination

Technical field

The utility model relates to a kind of LED light emission device, particularly a kind of LED encapsulation structure for plant illumination.

Background technology

Along with people are day by day strong to improving plant products and shortening the demand in crop cycle, artificial light sources starts to be applied to field of plant cultivation.

In the past, the conventional light source such as people's many employings fluorescent tube or high-pressure sodium lamp are used as " artificial sunlight ".But because these conventional illumination sources spectrum mate undesirable with plant photosynthesis absorption spectrum, therefore, it is possible to the light of the just indivedual wave band be absorbed by plants, the light of its all band is all wasted, not energy-conservation; Moreover conventional fluorescent or high-pressure sodium lamp power consumption are large, produce a lot of thermal radiation simultaneously, can not to plant irradiation at short distance, not high to plant growth light stimulus efficiency, considerably increase artificial lighting cost; In addition also light quality and light intensity regulating can not be carried out for the different qualities of different plant.

In recent years, people start to adopt new type light source LED to build plant lamp gradually, and find that it is than conventional light source, not only have heating less, the feature such as energy consumption is low, and can in order to the growth cycle of effective regulating plant.But existing LED plant illumination system adopts great power LED single tube to build mostly, it operationally, big current (300-700mA) is needed to drive, and, if contain the LED of different wave length, also need encapsulate separately with different chip package forms, and the LED of different wave length is driven separately, so just can carry out the mixing of the light of different wave length and the adjustment of ratio.So this type of illuminator generally exists following defect, comprising: heat dissipation problem is serious, needs fan cooled; Light efficiency is lower, takes electricity; Cost is high; Weight, volume are large.

Utility model content

The purpose of this utility model is to provide a kind of LED encapsulation structure for plant illumination, thus overcomes deficiency of the prior art.

For realizing above-mentioned utility model object, the utility model have employed following technical scheme:

For a LED encapsulation structure for plant illumination, it comprises the two or more LED chip be arranged in series, and wherein the operation wavelength of at least two LED chips is different from each other.

Further, the operation wavelength of described LED chip is 380nm-495nm.

Preferably, the drive current of described LED chip is 50mA-200mA.

Embodiment

Below in conjunction with some embodiments and accompanying drawing, more detailed explanation is done to the technical solution of the utility model.

Among an embodiment of the present utility model, a kind of LED encapsulation structure for plant illumination provided can comprise multiple LED chip, and wherein at least two LED chips are arranged in series, and wherein the operation wavelength of at least two LED chips is different from each other simultaneously.So, only need a small amount of driving power can drive whole plant illumination system, and provide driving power without the need to being respectively each LED chip.

Further, power during described LED chip preferably adopts, the LED chip of the current drives of such as 50-200mA.

Further, the LED chip of employing preferably comprises the different LED chip that operating wavelength range is 380nm to 495nm, thus realizes all standing from ultraviolet light to blue green light.

Further, also can coated red fluorescent material on part or all of LED chip wherein, nationality to realize the conversion of the wavelength of the light emitted line of LED chip, to meet for the different parts of different plant, plant, plant in the demand of Different growth phases for illumination wavelength.

Wherein, red light fluorescent powder can directly be coated in LED chip surface, also can be coated in the transparent encapsulation material surface of embedding LED chip, or, also can be coated in the surface of the far-end light guide plate coordinated with LED chip.

In addition, described LED encapsulation structure also can adopt the multiple packing forms known to industry.

Such as, please refer to shown in Fig. 1, in an embodiment of the present utility model, SMD support 2 can be adopted, and multiple LED chip 1 can be placed in the lock chamber on described package support, and in described lock chamber, be also filled with transparent encapsulation material 4, such as organic silica gel etc., and utilize red fluorescence powder 3 all to be covered lock chamber upper surface, so by the light that excites the different wave length that obtain plant growth needed for of each LED chip to fluorescent material.

Again such as, please refer to shown in Fig. 2, in another embodiment of the present utility model, can multiple LED chip 1 be placed in the lock chamber on SMD support 2, and also organic silica gel etc. is filled with in described lock chamber, and utilize red fluorescence powder 3 to cover, the subregion corresponding to part LED chip light extraction face of lock chamber upper surface so by the light that excites the different wave length that obtain plant growth needed for of each LED chip to fluorescent material.
