Abstract
The utility model relates to a LED lamp with a current-limiting resistance comprises epoxy resin, an anode rod, a cathode rod and a LED chip which are packaged in the epoxy resin, wherein, one end of the cathode rod packaged in the epoxy resin is connected with a bowl-shaped reflective cup, which is welded with the LED chip; one end of the anode rod packaged in the epoxy resin is welded with a current-limiting resistance, which is connected with the LED chip through a gold wire. The utility model is provided with the current-limiting function through the mode of packaging the current-limiting resistance chip in the LED epoxy resin, not only can well prevent the LED lamp from being damaged, but also can reduce the use cost of LED lamp belts.
Description
Technical field:
The utility model relates to the LED application technology, particularly be a kind of LED lamp with current-limiting resistance.
Background technology:
Light emitting diode (Light Emitting Diode, LED) invented the sixties in 20th century, it is to utilize electronics and hole in the semi-conducting material to mutually combine and give off energy, and makes rank, energy band (Energy Gat) position change, with its energy that is discharged of luminous demonstration.LED has advantages such as volume is little, the life-span is long, driving voltage is low, power consumption is low, reaction rate is fast, vibration strength is good, is widely used in fields such as signal indication, digital demonstration.
The LED power consumption is very low; in general the operating voltage of LED is 2-3.6V; when using LED to give instruction lamp; if supply voltage is too high; then LED may be burnt out; generation for fear of this situation; the general now current-limiting resistance of can on LED, connecting; to reach the purpose of protection LED; though this mode can well protect LED not to be damaged, need use different resistance corresponding with it for the LED lamp band of different numbers, not only can increase cost; and need to change resistance, whole process is very loaded down with trivial details.
Summary of the invention:
At above problem, the purpose of this utility model is to provide a kind of LED lamp that has current-limiting resistance, by current-limiting resistance being encapsulated in LED lamp inside, thereby solves the problem that LED lamp band needs to change resistance in use.
For achieving the above object, the utility model mainly is achieved through the following technical solutions:
A kind of LED lamp with current-limiting resistance, include epoxy resin and be encapsulated in anode rod, cathode rod and led chip in the epoxy resin, the end that cathode rod is packaged in the epoxy resin is connected with bowl-shape reflector, be welded with led chip in the described reflector, wherein anode rod is packaged in the interior end of epoxy resin and is welded with current-limiting resistance, and this current-limiting resistance is connected with led chip by gold thread.
Wherein said reflector inwall adopts reflecting material to make.
Wherein said led chip is a single pin.
Wherein said led chip is two pins.
The utility model makes the LED light fixture that metering function be arranged by the current-limiting resistance chip being packaged in the mode in the LED epoxy resin, not only can well protect the LED lamp not to be damaged, but also can reduce the use cost of LED lamp band.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is another example structure schematic diagram of the utility model.
Identifier declaration among the figure: 1 is that anode, 2 is that negative electrode, 3 is that led chip, 4 is that resistance, 5 is that reflector, 6 is that gold thread, 7 is an epoxy resin.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
The utility model is a kind of LED lamp with current-limiting resistance, include epoxy resin 7 and be encapsulated in anode rod 1, cathode rod 2 and led chip 3 in the epoxy resin 7, the end that cathode rod 2 is packaged in the epoxy resin 7 is connected with bowl-shape reflector 5, be welded with led chip 3 in the described reflector 5, wherein anode rod 1 is packaged in the interior end of epoxy resin and is welded with current-limiting resistance 4, and this current-limiting resistance 4 is connected with led chip 3 by gold thread 6.
As shown in Figure 1, Fig. 1 is the utility model preferred implementation one, and wherein led chip 3 is a single pin, and this pin is connected by the current-limiting resistance 4 of gold thread 6 and anode tap, the bottom of this led chip 3 and reflector 5 weld together, and are connected with cathode rod 2 by its bottom.
As shown in Figure 2, Fig. 2 is the utility model preferred implementation two, and wherein led chip 3 is two pins, and a pin is connected by the current-limiting resistance 4 of gold thread 6 and anode tap, and an other pin then directly is connected with cathode rod 2.
In addition, also current-limiting resistance 4 can be welded on the cathode rod 2 in the utility model structure, the resistance of current-limiting resistance 4 can be set to difference according to different needs here, and according to the big I of resistance this LED lamp is applied in the LED lamp band of different numbers.
More than a kind of LED lamp with current-limiting resistance described in the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand core concept of the present utility model; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
