Abstract
The utility model relates to the luminous product technical field, particularly to an LED light-emitting device which comprises an LED lamp or a lamp group and power input and output lead wires connected with the LED lamp or the lamp group, wherein the input lead wire is connected with a resistor, and the output lead wire is connected with a diode. As the further improvement of the technical scheme, the resistor is a thermal resistor with a positive temperature coefficient. After the LED light-emitting device adopts the technical scheme, firstly, the diode with a unilateral conduction function can prevent the counter current from passing through the diode to prevent the LED light-emitting device from being damage by the counter current. Then, the LED light-emitting device regulates the wording voltage of the LED lamp or the lamp group to regulate the generation of the heat through the thermal resistor with a positive temperature coefficient. The utility model can be widely applied to various commodities and equipment such as apparatus and indicating and illuminating apparatus of an automobile which requires light. Compared with the existing like products, the utility model has the advantages of long service life and stable operation.
Description
Technical field:
The utility model relates to the luminous product technical field, refers in particular to a kind of LED light-emitting device.
Background technology:
Because LED (light emitting diode) has plurality of advantages such as energy consumption is little, volume is little, so be widely used in social production, the life.For example, the instrument board display lamp in the automobile.But adopt the LED light-emitting device in use also to have certain problem at present: one, when LED in when work, it can produce certain heat, metapyretic LED will influence its performance if be positioned at a higher temperature for a long time; Its two, present LED is in when work, if it is reverse that electric current takes place, reverse electric current will smash LED, cause the light-emitting device damage.These deficiencies have all influenced the quality and the security performance of product, bring very big trouble to the user.
The utility model content:
Technical problem to be solved in the utility model just is to overcome the defective of prior art, and a kind of LED light-emitting device that can effectively improve product quality is provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: it comprises, and LED lamp or lamp group and the power supply that is connected with LED lamp or lamp group are imported, output lead, on input lead, be connected with a resistance, on output lead, be connected with a diode.
As the further improvement to the aforementioned techniques scheme, described resistance is the thermistor of a positive temperature coefficient.
The utility model at first utilizes the unilateal conduction function of diode to prevent that reversing the current from passing through diode after adopting technique scheme, does not smash thereby protection LED can not be reversed electric current.Secondly, regulate the operating voltage of LED lamp or lamp group, thereby regulate the generation of its heat by semistor.The utility model can be widely used in various products, the equipment, for example needs on the automobile on the instrument, indication, lighting device of light, and it has the advantage of long service life, working stability with respect to present like product.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
See Fig. 1, the utility model comprises: LED lamp group 1, circuit board 10 and the power supply input, the output lead 2,3 that are connected with LED lamp group 1.Wherein lamp group 1 that is made of several LED lamps and input, output lead 2,3 all are connected on the circuit board 10.And on input lead 2, be connected with a resistance 4, on output lead, be connected with a diode 5.The utility model utilizes the unilateal conduction function of diode 5 to prevent that reversing the current from smashing LED.
The lamp that the also single LED of above-mentioned LED lamp group 1 constitutes is not limited only to the lamp group that a plurality of LED constitute.
In addition, in order to improve security performance of the present utility model, above-mentioned resistance 4 adopts a semistor, and promptly along with the rising of temperature, the resistance of resistance 4 also increases.Adopt this kind thermistor, temperature around LED lamp group 1 causes owing to working long hours raises, the resistance of resistance 4 also will increase, the voltage that is carried in resistance 4 two ends so also improves thereupon, so just play the dividing potential drop effect, thereby the operating power of LED lamp group 1 is descended, and heat also decreases, thereby plays the operating temperature of regulating LED lamp group 1.
The embodiment of the above, be the preferred embodiments of the utility model only, be not to limit the utility model practical range, so all variation or modifications of doing according to the described structure of the utility model claim, feature and principle all should be included in the utility model claim.
Claims (2)
1, a kind of LED light-emitting device, comprise: LED lamp or lamp group (1) and the power supply input, the output lead (2,3) that are connected with LED lamp or lamp group (1), it is characterized in that: on input lead (2), be connected with a resistance (4), on output lead, be connected with a diode (5).
