Abstract
The utility model discloses a kind of light source arrangements suitable for LED light bar, and including bar shaped substrate and several LED chips, several LED chips are linearly arranged on the bar shaped substrate, and draw two electrodes by the both ends of the bar shaped substrate；The LED chip is divided into two series connection lamp groups and a lamp group in parallel, and two series connection lamp group is arranged at two sides of the bar shaped substrate, and the parallel connection lamp group is arranged at the middle part of the bar shaped substrate, and is sequentially connected between two electrodes.The utility model provides a kind of light source arrangement suitable for LED light bar, extends the service life of LED light bar, while also makes it possible the LED chip of setting higher wattage.
Description
Technical field
The utility model is related to a kind of light source arrangements, arrange more particularly to a kind of light source suitable for LED light bar
Structure.
Background technology
With the gradual modularization of LED illumination product, miniaturization, heat dissipation performance also becomes one and considers LED illumination product
The important indicator of quality.Different LED illumination products are required to design specific radiator structure according to its design feature, to ensure
The heat that LED light source generates can dissipate in time, and then ensure the service life of LED illumination product.
Bar-shaped LED lamp bar is a kind of common LED product module.Since the electrode of LED light bar is arranged at the two of LED light bar
Side, when being installed in LED product, pad also is located at the both sides of LED light bar.Under this design feature, heat that LED light bar is sent
It is dissipated after needing conduction to both sides, it is more than both sides just necessarily to cause the caloric value in the middle part of lamp bar.And then cause the LED chip at middle part
It is chronically under higher temperature, service life is affected.
Utility model content
The purpose of the utility model is to overcome the deficiencies of the prior art, provide a kind of light source suitable for LED light bar
Arrangement extends the service life of LED light bar, while also makes it possible the LED chip of setting higher wattage.
Technical solution is used by the utility model solves its technical problem：A kind of light source suitable for LED light bar is arranged
Cloth structure, including bar shaped substrate and several LED chips, several LED chips are linearly arranged on the bar shaped substrate, and by this
Draw two electrodes in the both ends of bar shaped substrate；The LED chip is divided into two series connection lamp groups and a lamp groups in parallel, described two
Series connection lamp group is arranged at two sides of the bar shaped substrate, and the parallel connection lamp group is arranged at the middle part of the bar shaped substrate, and sequentially connects
Between two electrodes.
As a preferred embodiment, each LED chip in the parallel connection lamp group is electrically connected with LED chip separately,
And form two parallel branches.
As a preferred embodiment, the surface of several LED chips is coated with fluorescent glue.
As a preferred embodiment, the bar shaped substrate is using sapphire material or ceramic material or heat conduction glass material.
The beneficial effects of the utility model are：The light source arrangement of LED light bar is designed as structure that is interior and going here and there outside, is made
The electric current for obtaining parallel connection part is only the half of part in series electric current, and then the caloric value at middle part is made to be less than both sides.Coordinate LED light bar
Integral heat sink structure, the heat dissipation for making LED light bar entirety is more balanced.The service life of LED light bar is extended, while also makes to set
The LED chip for putting higher wattage is possibly realized.
The utility model is described in further detail with reference to the accompanying drawings and embodiments；But one kind of the utility model is fitted
Embodiment is not limited to for the light source arrangement of LED light bar.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the exploded perspective view of the utility model.
Specific embodiment
Embodiment：
Referring to shown in Fig. 1 to Fig. 2, a kind of light source arrangement suitable for LED light bar of the utility model, including bar shaped
Substrate 3 and several LED chips 1, several LED chips 1 are linearly arranged on the bar shaped substrate 3, and by the bar shaped substrate 3
Draw two electrodes 2 in both ends；The LED chip 1 is divided for two series connection lamp groups 11 and a lamp group 12 in parallel, two series connection
Lamp group 11 is arranged at two sides of the bar shaped substrate 3, and the parallel connection lamp group 12 is arranged at the middle part of the bar shaped substrate 3, and sequentially connects
It is connected between two electrodes 2.
Each LED chip 1 in the parallel connection lamp group 12 is electrically connected with LED chip 1 separately, and forms two
Parallel branch.Shown in Figure 1, the LED chip 1 in the middle part of lamp bar is connected respectively with LED chip 1 separately, makes interval setting
LED chip 1 connect respectively formed two parallel branches.The circuit that so connection is formed, conductor length are impartial, and caloric value is also more
For equilibrium.
The surface of several LED chips 1 is coated with fluorescent glue 4.The fluorescent glue 4 is used to convert the illumination color of LED light bar
Coloured silk or the illuminating effect for improving LED chip 1.
All LED chips 1 are interconnected by gold thread 5.The bar shaped substrate 3 uses sapphire material or ceramic material
Or heat conduction glass material.
Above-described embodiment is only used for further illustrating a kind of light source arrangement knot suitable for LED light bar of the utility model
Structure, but the utility model is not limited to embodiment, it is every that above example is made according to the technical essence of the utility model
Any simple modification, equivalent change and modification, each fall in the protection domain of technical solutions of the utility model.
