Background technique
It is improved with the development of society, people's lives are horizontal continuous, LED light is indispensable at finishing in for people's lives
A part, the application of the product of LED is also more and more extensive in current life, still, as shown in figure 5, design LED light correlation produces
Product are the electric currents it should be noted that LED light, and the electric current of specification requirement LED light must could be worked normally in 20mA or more, such as Fig. 6 institute
Show, and the operating voltage requirement of LED controls between 1.8-2.6V, when voltage is more than this orientation, the electric current of LED light will
Steeply rise, and when electric current rises, the temperature of LED light will follow current rising and rise, as shown in fig. 7, temperature increases
While will cause lamp bead and reduced using the time so that LED lamp bead is burnt, in order to extend the service life of LED light, be
This, it is proposed that a kind of constant current LED lamp.
Summary of the invention
The main purpose of the present invention is to provide a kind of constant current LED lamps, can effectively solve the problems in background technique.
To achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of constant current LED lamp, including LED light main body and power supply are provided on the encapsulation architecture of the LED light body interior
LED wafer and high voltage and constant current chip are connected between the LED wafer and high voltage and constant current chip by conducting wire.
Preferably, the cathode connection of one end and power supply far from LED wafer of the high voltage and constant current chip, the LED wafer
The anode of one end and power supply far from high voltage and constant current chip connects.
Compared with prior art, it the present invention provides a kind of constant current LED lamp, has the following beneficial effects:
LED wafer and high voltage and constant current chip are closed into envelope into same encapsulation architecture, electric current can pass through high voltage and constant current when use
Chip can maintain the electric current Jing Guo LED wafer under high-pressure situations, and it is corresponding that design is not needed in LED light design process
Power resistor can reduce the process and cost when LED light production without considering the cooperation of LED light and power resistor when production,
And entire constant current LED lamp is relatively simple for structure, and using effect is more preferable relative to traditional approach, and the use for meeting people is wanted
It asks.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
In the description of the present invention, it is to be understood that, term " on ", "lower", "front", "rear", "left", "right", "top",
The orientation or positional relationship of the instructions such as "bottom", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, merely to just
In description the present invention and simplify description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with
Specific orientation construction and operation, therefore be not considered as limiting the invention.
A kind of constant current LED lamp, as shown in Figure 1, including LED light main body and power supply, on the encapsulation architecture of LED light body interior
It is provided with LED wafer and high voltage and constant current chip, is connected between LED wafer and high voltage and constant current chip by conducting wire.
The cathode of high voltage and constant current chip one end and power supply far from LED wafer connects, and LED wafer is far from high voltage and constant current chip
One end and power supply anode connect.
Embodiment 1
As shown in figure 4, Fig. 4 is the application circuit figure of existing 110V Christmans light string, it is holy which is applied to 110V
Its positive pole connection several groups LED light and power resistor, connect finally by conducting wire with power cathode in absurd fantastic lamp string；
As shown in figure 3, Fig. 3 is the line map of this constant current LED lamp, after the anode of power supply connects existing several groups LED light
It connect with constant current LED lamp of the invention, is connect finally by conducting wire with power cathode；
Constant current LED lamp is arranged in last position, without using the power resistor of current limliting, is able to maintain that in use process
The electric current of each LED light of lamp string is stablized, and can play the role of protecting lamp string, and without considering temperature caused by overtension
The excessively high damage to LED light, installation and use it is more convenient, and using when circuit in high pressure be concentrated in high voltage and constant current
Chip, voltage will not influence LED light, avoid the occurrence of voltage it is excessive cause LED light electric current become larger temperature raising cause LED light to be burnt
The case where, so as to extend the service life of LED light；
It should be noted that the present invention is a kind of constant current LED lamp, LED wafer and high voltage and constant current chip are closed and are sealed to same by box
In one encapsulation architecture, electric current can pass through high voltage and constant current chip when use, can maintain to pass through LED wafer under high-pressure situations
Electric current, does not need to design corresponding power resistor in LED light design process, without considering LED light and power resistor when production
Cooperation can reduce process and cost when LED light production, and relatively simple for structure, the using effect of entire constant current LED lamp
It is more preferable relative to traditional approach, meet the requirement of people.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
