The utility model discloses the beneficial effect who has: have two chips can send wavelength 440nm and 460nm's blue light separately after the circular telegram, this moment phosphor powder can absorptive wavelength 440nm with 460nm's blue light and send the required broadband blue light of plant. The lamp body is only 10~15 DEG C high than ambient temperature, can control within 40 DEG C surface of lamp body closely that the light filling can not cause the injury or influence ambient temperature in a large number the plant, and the wavelength is fit for vegetation completely.

Description

A kind of LED Filament and use the special bulb of plant growing of this filament

Technical field

This utility model relates to a kind of LED filament and uses the special bulb of plant growing of this filament, belongs to illumination according to tool technical field.

Background technology

nullBefore 30 years, NASA Mars program propose the artificial isolation environment of plant to cultivate the probability grown up in the outer space is plant factor's concept the earliest，Plant factor is current field of plant cultivation advanced technology the most，It is the tidemark of cultivation mode development，In plant factor, light-supplementing system is of paramount importance system，It is a kind of main energy sources constituting phytomass，There is no illumination，Photosynthesis of plant cannot be normally carried out，Energy needed for all metabolism and activity cannot supply，The normal growth of plant cannot be carried out，According to scientist, the research for many years of illumination is shown，The photosynthesis unit chlorophyll of plant has hobby for the light source of specific band，Such as HONGGUANG、Blue light、Far-red light，In addition to these light，The illumination utilization rate conversion ratio of other light quality is the highest，There is harmful effect the most on the contrary，In order to make the plant in plant factor have higher photosynthetic efficiency，Being typically chosen red blue light is main artificially feed system，But the narrow frequency spectrum of the single wavelength of LED but cannot play comprehensive therefore the present invention is then to manufacture a wide spectrum blue light.

Current LED filament lamp is not appropriate for for plant illumination as illumination use, plant illumination need for wide spectrum blue light and wide spectrum HONGGUANG.The design of all of lamp is flowed in Single wavelength, simultaneously because illuminating module is typically accompanied by relatively high power is not suitable for irradiation at short distance with higher temperature, its temperature can affect the growth of plant.

Utility model content

The purpose of this utility model is to overcome deficiency of the prior art, a kind of LED filament is provided and uses the special bulb of plant growing of this filament, lamp body granule surface contral closely can will not can be damaged or affects in a large number ambient temperature, and the entirely appropriate plant growing of wavelength by light filling within 40 DEG C to plant.

For solving prior art problem, the technical solution adopted in the utility model: the utility model discloses a kind of LED filament, including substrate, some LED chip, and the silica gel each LED chip being encapsulated on substrate；LED chip at least includes 440～445nm wave band chips and 460～465nm wave band chips；Silica gel is mixed with and can absorb blue light energy and inspire the fluorescent material of 620～660nm wave band blue lights.

Preferably, LED filament also includes transparent even light pipe, and substrate is contained in even light pipe and is connected with the two ends of even light pipe by the fixing head at its two ends.

Preferably, substrate is made up of glass or the ceramic material of printing opacity.

Preferably, LED chip is fitted on substrate in upside-down mounting mode.

Preferably, LED chip is respectively 440nm chip and 460nm chip.

The invention also discloses the special bulb of a kind of plant growing using above-mentioned LED filament to make, including glass shell, and some LED filament, LED filament is arranged in series in glass shell.

Preferably, it is marked with helium in glass shell.

This utility model has the advantages that

1, two chips are had can each to send the blue light of wavelength 440nm and 460nm, the broadband blue light needed for now fluorescent material is understood absorbing wavelength 440nm and the blue light of 460nm and sent plant after energising.

2, lamp body is higher 10～15 DEG C than ambient temperature, closely plant can will not damage or affect in a large number light filling ambient temperature, and the entirely appropriate plant growing of wavelength by lamp body granule surface contral within 40 DEG C.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is further described.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.

If Fig. 1 is to shown in 5, a plant growth special lamp bubble, including glass shell 5, and the LED filament being serially connected in being sealed in glass shell 5, it is marked with helium in glass shell 5.

Wherein, LED filament includes substrate 1, some LED chip 7, and each LED chip 7 encapsulates silica gel 6 on substrate 1, and the transparent even light pipe of storage substrate 1.Substrate 1 is made up of glass or the ceramic material of printing opacity, and LED chip 7 is fitted on substrate 1 in upside-down mounting mode.LED chip 7 includes 440～445nm wave band chips and 460～465nm wave band chips, preferably 440nm and 460nm chip.Silica gel 6 is mixed with can absorb blue light energy to inspire the Nitride phosphor of 620～660nm wave band blue lights, the i.e. emission band of this fluorescent material be 620～660nm, adjusts both mixed proportions and make the bluish red light sent than about 1:7～1:9.The two ends of substrate 1 are provided with fixing head 3 and pin 2, and fixing head 3 is provided with a pair outwardly directed side plate 4, and even light pipe is arranged between two fixing head 3 and is fixed by side plate 4, are connected by pin 2 between LED filament.

Because LED chip 7 only surface coating, the heat of LED chip 7 is conducted to side and the back side through base material.Helium thermal conductivity is 0.1426W/mK, about 6 times of air, thermal agitation air-flow can be produced inside when producing heat, air-flow one occurs thermal conductivity to be that 5～20 times of heat uniformly could not accumulated on substrate 1 rapidly according to Air flow velocity, the even light pipe of hollow forms a stack effect heat and quickly discharges acceleration thermal cycle from top, by the torrid zone to glass shell 5 surface, in pipe, air velocity can exceed outside pipe.Even light pipe is except causing stack effect and in optically reflecting light to rear.

In this utility model, the numeral in described 440～445nm wave band chips and 460～465nm wave band chips refers to the specification of chip, such as 440nm chip, 445nm chip, 460nm chip etc., therefore no longer repeats.

The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvement and deformation, these improve and deformation also should be regarded as protection domain of the present utility model.
