The utility model discloses a color of tube uniformity is protected, and the colour temperature concentration degree is high, can dispose out different colour temperatures, different color rendering index ra, the compound white light LED of different light efficiencies, not only practice thrift the cost, and production efficiency is high.
Description
Technical field
The utility model relates to LED technology field, be specifically related to a kind of high light efficiency LED illumination light assembly.
Background technology
The advantages such as LED fluorescent lamp tube is energy-conservation to have, environmental protection, and the life-span is long are called as the green illumination light source of 21 century.The appearance of LED fluorescent lamp tube becomes the main flow of market lighting field, and each large advantage of LED fluorescent lamp tube obtains acceptance and the accreditation of consumer in illumination applications.Its luminous efficiency is that traditional lighting lamp is incomparable far away, and the whole world is all what advocate just in energy-conserving and environment-protective, and LED energy-conserving and environment-protective obtain the attention of country.
LED fluorescent lamp tube, classifies according to the surface structure of fluorescent tube, can be divided into: " transparent type " and " vaporific type "; According to LED light source classification of type, can be divided into: " plug-in type " and " patch-type "; The current industry technology main flow of its technique is: blue light wafer surface encapsulation fluorescent glue (fluorescent glue consists of: the fluorescent material such as silica gel mixing is yellow, redness, green or yellow green), fluorescent glue excites compound by blue light wafer thus produces white light, but above-mentioned fluorescent tube processing disadvantages is:
1. current fluorescent tube on the market, substrate is FR4 plate or conventional aluminium substrate, and its conductive coefficient is respectively: 1W/mk, 1.5W/mk and 2W/mk, and this two substrate also exists some bottlenecks at present in heat conduction.When fluorescent tube is lighted for a long time, its internal heat can increase, because silica gel heatproof is limited, when internal temperature is too high, LED heat radiation can be deteriorated, and the fluorescent material inside fluorescent glue volatilizees because being heated, and LED colour temperature (CCT) produces drift, colour consistency is deteriorated, and there will be aberration and hot spot when client uses;
2. when client's instructions for use is changed (colour temperature is altered to 6000K by 3000K), then need all LED to replace, or directly change whole lamp bar, reprocess difficulty, reprocess cost high, inventory disposal rate is high.
Utility model content
For the deficiency that prior art exists, the utility model object is to provide a kind of high light efficiency LED illumination light assembly, and fluorescent tube colour consistency is protected, and colour temperature concentration degree is high, configurable go out different-colour, different color rendering index Ra, the recombined white light LED of different light efficiency; Not only cost-saving, and production efficiency is high.
To achieve these goals, the utility model realizes by the following technical solutions: high light efficiency LED illumination light assembly, comprise substrate, LED chip, packaging silicon rubber, PC cover and high temperature fluorescent film, substrate is packaged with multiple series-parallel LED chip by packaging silicon rubber, LED chip afterbody is provided with PC cover, and PC cover posts high temperature fluorescent film.
As preferably, described LED chip, packaging silicon rubber composition blue-ray LED.
As preferably, described high temperature fluorescent film is the fluorescent powder membrane of different colours.
The beneficial effects of the utility model:
1. on high temperature membrane fluorescent material on even application (high temperature fluorescent film may be yellow, red, green or yellow green hybrid films), then high temperature fluorescent film is covered on PC cover, because fluorescent material is away from light source, the heat that fluorescent material is subject to reduces, and the probability of fluorescent material generation chemical reaction reduces greatly, fluorescent tube colour consistency is protected, and colour temperature concentration degree is high; Its two: the adaptive different types of high temperature fluorescent film of different types of blue LED wafers, configurable go out different-colour, different color rendering index Ra, the recombined white light LED of different light efficiency;
2. when client's instructions for use is changed, without the need to changing LED, only need to change high temperature fluorescent film, reprocess quick, utilization of materials is high, not only cost-saving, and production efficiency is high.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is decomposition texture schematic diagram of the present utility model.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
With reference to Fig. 1, this embodiment is by the following technical solutions: high light efficiency LED illumination light assembly, comprise substrate 1, LED chip 2, packaging silicon rubber 3, PC cover 4 and high temperature fluorescent film 5, substrate 1 is packaged with multiple series-parallel LED chip 2 by packaging silicon rubber 3, LED chip 2 afterbody is provided with on PC cover 4, PC cover 4 and posts high temperature fluorescent film 5.
It should be noted that described LED chip 2, packaging silicon rubber 3 forms blue-ray LED.
In addition, described high temperature fluorescent film 5 is the fluorescent powder membrane of different colours.
High temperature fluorescent film, is attached on PC cover by many blue-ray LED connection in series-parallel of this embodiment together, and blue-ray LED is combined with the PC cover of different colours and excites compound to produce white light.
This embodiment on high temperature membrane fluorescent material on even application (high temperature fluorescent film may be yellow, red, green or yellow green hybrid films), then high temperature fluorescent film is covered on PC cover, because fluorescent material is away from light source, the heat that fluorescent material is subject to reduces, and the probability of fluorescent material generation chemical reaction reduces greatly, fluorescent tube colour consistency is protected, and colour temperature concentration degree is high; The adaptive different types of high temperature fluorescent film of different types of blue LED wafers, configurable go out different-colour, different color rendering index Ra, the recombined white light LED of different light efficiency.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
