Abstract
The utility model discloses an anti high temperature fluorescent screen LED light source belongs to LED light source technical field. The middle part of base plate (1) is provided with several blue light wafer (2), and several blue light wafer (2) forms the LED light source by the mutual series connection of wire, being provided with external power supply line to the angular position and connecting (3) of base plate (1), and the top of LED light source is packaged with substratum transparent (4), and the top of substratum transparent (4) covers has high temperature UV fluorescent screen (5). Its reasonable novel light source of structural design and high temperature UV fluorescent screen size structure perfect combination, the assembly is simple, reprocesses the convenience. UV membrane effective isolation external ultraviolet ray, reduced external injury to LED, product reliability and life -span obtain further promotion.
Description
Technical field
The utility model relates to a kind of high temperature resistance fluorescent film LED light source, belongs to LED light source technical field.
Background technology
LED is since appearance, in widespread attention and obtain fast development, and this and itself are advantageously inseparable.These advantages sum up and are: luminous efficiency is high, energy-saving and environmental protection, the life-span is long, application flexibility is high, shock-resistant and stable performance.The development prospect of LED is very wide, at present just towards future developments such as higher brightness, higher luminous density, higher uniformity of luminance and stronger weatherabilitys.
Current industry technology main flow is, blue light wafer surface encapsulation fluorescent glue (glue mixing is yellow, red, green, yellowish green waits fluorescent material), excites compound thus produce white light by blue light wafer.But this kind of processing disadvantages is:
1. silica gel heatproof is limited, and when temperature is too high, product heat radiation can be deteriorated, and the fluorescent material inside fluorescent glue can volatilize, and product colour temperature (CCT) produces drift, and colour consistency is deteriorated, and client uses this product to there will be aberration and hot spot;
When 2.LED light source works out of doors, can receive ultraviolet for a long time, UV and silica gel react, and colloid surface is ftractureed, and affect its life-span;
3., because blue light wafer and fluorescent glue belong to one-shot forming (integral type), therefore cannot reprocess, when there is quality problem, can only scrap, manufacturing cost is high.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of high temperature resistance fluorescent film LED light source.
The utility model high temperature resistance fluorescent film LED light source, it comprises substrate 1, blue light wafer 2, external power supply wire terminal 3, substratum transparent 4 and high temperature UV fluorescent film 5, the middle part of substrate 1 is provided with several blue light wafer 2, several blue light wafer 2 is mutually connected in series by wire and forms LED light source, the diagonal position of substrate 1 is provided with external power supply wire terminal 3, the top of LED light source is packaged with substratum transparent 4, and the top of substratum transparent 4 is coated with high temperature UV fluorescent film 5.
As preferably, described high temperature UV fluorescent film 5 is that even application fluorescent material is formed on high temperature UV film.
As preferably, described high temperature UV fluorescent film 5 is the UV fluorescent film of yellow red green or yellowish green mixing.
The beneficial effects of the utility model: it can overcome the drawback of prior art, reasonable in design light source and high temperature UV fluorescent film dimensional structure perfect combination, assembling is simple, reprocesses conveniently.UV film has effectively isolated extraneous ultraviolet, and reduce the injury of outer bound pair LED, product reliability and life-span are promoted further.
accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation that the utility model does not encapsulate substratum transparent and high temperature UV fluorescent film;
Fig. 3 is the structural representation that the utility model does not encapsulate high temperature UV fluorescent film.
embodiment:
As Figure 1-3, this embodiment is by the following technical solutions: it comprises substrate 1, blue light wafer 2, external power supply wire terminal 3, substratum transparent 4 and high temperature UV fluorescent film 5, the middle part of substrate 1 is provided with several blue light wafer 2, several blue light wafer 2 is mutually connected in series by wire and forms LED light source, the diagonal position of substrate 1 is provided with external power supply wire terminal 3, the top of LED light source is packaged with substratum transparent 4, and the top of substratum transparent 4 is coated with high temperature UV fluorescent film 5.
As preferably, described high temperature UV fluorescent film 5 is that even application fluorescent material is formed on high temperature UV film.
As preferably, described high temperature UV fluorescent film 5 is the UV fluorescent film of yellow red green or yellowish green mixing.
The preparation method of this embodiment is: by the blue light wafer 2 of the coloured light that turns blue, by die bond, bonding wire, encapsulation substratum transparent 4 after make blue-light source, high temperature UV fluorescent film 5 is covered above blue-light source, both compounds thus produce white light.
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
