Abstract
The utility model provides an improved three-core SMD (Surface Mounted Device) LED. The improved three-core SMD LED adopts the structure that three LED chips, platelike copper foils and a packaging shell are arranged on a printed circuit board (PCB); the LED chips are connected with the platelike copper foils; the packaging shell is arranged on the periphery of the LED chips. The improved three-core SMD LED is characterized in that each LED chip is provided with a group of the independent platelike copper foils which are connected to form an independent positive pole and negative pole. Through the adoption of the structure, each chip is provided with a group of the independent platelike copper foils which are connected to form the independent positive pole and negative pole so as to realize independent control, and meanwhile, the three chips are uniformly distributed in the middle of the PCB, so that the illumination effect of the LED is enhanced, and the color diversity of the LED is realized. Each chip is provided with the independent positive pole and negative pole, and can be free of influence of other control circuits in a circuit, so that the practicability of the SMD LED is enhanced; the three-core SMD LED is compact in integral structure, small and exquisite in size, convenient to weld and replace for use, simple and convenient to use in the circuit, and particularly suitable for fields such as toys and ornaments.
Description
Technical field
The utility model relates to a kind of LED lamp, particularly a kind of three color chip paster LED lamps.
Background technology
Nowadays in energy-conservation epoch, LED has been widely used in social industry-by-industry, and a kind of adopting surface mounted LED of the long-term flicker that powers on can be realized several colors regularity, periodically flicker, can apply to widely the aspects such as toy, ornament.The current small-sized periodicity of the using three color chip paster LEDs that glimmer, only have two or four pin, when a chip number is at three time, can not completely independently control each chip, arrangement architecture in use, easily causes the damage of chip and affects the diversity of color like this.And the arrangement of chip is compact not, is subject to the restriction arranged evenly of plate Copper Foil simultaneously, and chip all can not, in the centre of LED board, affect its illumination effect.Every chips is luminous, is subject to the impact of other control circuit in circuit, and unfavorable practical operation is used, and there is no better practicality.
Summary of the invention
For addressing the above problem, effectively improve being uniformly distributed and effectively independent control of three chip LED chips, improve luminous efficiency, color diversity and practicality, the utility model provides a kind of three chip LEDs of improvement, comprise that pcb board is provided with LED chip, plate Copper Foil, encapsulating shell, described LED chip is connected with plate Copper Foil, encapsulating shell is located at the outer of LED chip and places, it is characterized in that: described LED chip is three, each LED chip is provided with independently one group of plate Copper Foil and is connected to form independently positive and negative end.
The both positive and negative polarity extreme direction of three described LED chips is identical.
Three described LED chips are located at pcb board center and are positive triangle arrangement.
The height of described encapsulating shell is 0.3mm.
Adopt after said structure, each LED chip is provided with independently one group of plate Copper Foil and is connected to form independently positive and negative end and can realizes independently and controlling, simultaneously three chips be evenly distributed on pcb board center, strengthened its illumination effect and color diversity.And every chips has independently both positive and negative polarity, be no longer subject to the impact of other control circuit in circuit, the practicality of its paster LED of enhancing.Its compact overall structure, compact size, easily welding and easily replacement use, it is also simple, convenient in circuit, to use, and is specially adapted to the aspects such as toy, ornament.
The utility model is simple in structure, practical, improves usability, the validity and ornamental of product.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model one side view.
In figure, be denoted as:
1PCB plate, 2LED chip, 3 plate Copper Foils, 4 encapsulating shells.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model title is described in further detail, but does not form any restriction of the present utility model.
As shown in Figure 1, 2:
A kind of three chip LEDs of improvement, comprise that pcb board 1 is provided with LED chip 2, plate Copper Foil 3, encapsulating shell 4, described LED chip 2 is connected with plate Copper Foil 3, encapsulating shell 4 is located at the outer of LED chip 2 and places, it is characterized in that: described LED chip 2 is three, each LED chip 2 is provided with independently one group of plate Copper Foil 3 and is connected to form independently positive and negative end.Each LED chip is provided with independently one group of plate Copper Foil and is connected to form independently positive and negative end and can realizes independently and controlling, the pcb board that is evenly distributed on of three chips hits exactly simultaneously, strengthened its illumination effect, in control procedure, can realize alternately flicker or by controlling its luminosity of each chip, to reach, realize color diversity.And every chips has independently both positive and negative polarity, be no longer subject to the impact of other control circuit in circuit, the practicality of its paster LED of enhancing.
As technology, further improve, the both positive and negative polarity extreme direction of three described LED chips 2 is identical, operation welding easy to use.
As technology, further improve, three described LED chips 2 are located at pcb board 1 center and are positive triangle arrangement together, realize and concentrate on pcb board center, have strengthened its illumination effect.
As technology, further improve, the height of described encapsulating shell 4 is 0.3mm, and implementation structure is compact, compact size, and the scope of application is wide, the usability of raising product and ornamental.
The utility model compact overall structure, compact size, easily welding and easily replacement use, it is also simple, convenient in circuit, to use, and is specially adapted to the aspects such as toy, ornament.
