Abstract
The utility model provides a high-voltage low-current LED lamp bead. The high-voltage low-current LED lamp bead comprises a support body, the support body is provided with an LED chip, an anode and cathode metal connecting piece, and a silica gel layer, the LED chip is connected with the anode and cathode metal connecting piece, and the silica gel layer is arranged at the upper part of the LED chip. The high-voltage low-current LED lamp bead is characterized in that the LED chip is a series-connected integral chip block formed by the splicing of several small chips with built-in metal wires. By adopting the above structure, the LED chip is the series-connected integral chip block formed by the splicing of several small chips with the built-in metal wires, the LED lamp bead with high voltage, low current and high luminous effect is realized, in the condition of high luminous effect, the operating current of the lamp bead is reduced, the connection and welding of the metal wires in the structure are omitted, the chips and the metal wires are spliced together to form the integral chip block, the position of die bond is not needed to be considered in the making process, the manufacturing processes are simplified, and the production efficiency is improved.
Description
Technical field
The utility model relates to the LED lamp pearl of a kind of LED lamp, particularly high pressure low current.
Background technology
Nowadays in energy-conservation epoch, LED has been widely used in social industry-by-industry, in the application of LED, brightness and heat radiation are large problems facing always, reduce and use electric current, can reduce electric energy conversion and become heat energy, but brightness (light efficiency) also can decline.
Use electric current reducing lamp pearl, does not affect light efficiency situation, and many low power chips of can considering to connect can be realized the use electric current that reduces lamp pearl in the situation that does not reduce light efficiency.According to the mode that adopts welded wire between existing chip and chip, be connected in series and realize low current, still series connection chip is not carried out to bonding wire to die bond position and have high requirement, use a large amount of gold threads to connect chip wherein, for example, if 8 lamp pearls that little chip forms, need with 9 gold threads, 8 chips wherein and the both positive and negative polarity of metal connecting piece material to be cascaded, wherein one or line is bad causes whole material to be scrapped.Complex manufacturing technology, and have a big risk, efficiency is low, is not easy management and control.
Summary of the invention
For addressing the above problem, effectively realize the high light efficiency LED lamp pearl of high voltage low current, can realize simplification manufacture craft, enhance productivity, improve the quality of product, service efficiency and practicality, the utility model provides a kind of LED lamp pearl of high voltage low current, comprise stake body, described stake body is provided with LED chip, both positive and negative polarity metal connecting piece, Gui glue-line, LED chip is connected with both positive and negative polarity metal connecting piece, Gui glue-line is located at LED chip top, it is characterized in that: described LED chip is spliced to form a whole chip block of series connection by several little built-in chip type wires.
The positive pole of described little chip and negative pole are 90 degree angles and are arranged in chip dual-side.
The most suitable quantity of a number of the little chip in described LED chip is 8.
Adopt after said structure, LED chip is spliced to form a whole chip block of series connection by several little built-in chip type wires, realize the high light efficiency LED lamp pearl of high voltage low current, realize the use electric current that reduces lamp pearl in the situation of high light efficiency, in structure, save the connecting welding of gold thread, form whole chip block with being merged together, in manufacturing process and need not consider die bond position, manufacture craft has been simplified in realization, enhances productivity.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that little chip 21 chips are connected side-looking enlarged drawing with chip.
In figure, be denoted as:
1 stake body, 2LED chip, 3 both positive and negative polarity metal connecting pieces, 4 Gui glue-lines, 21 little chips, 211 wires.
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 LED lamp pearl of high voltage low current, comprise stake body 1, described stake body 1 is provided with LED chip 2, both positive and negative polarity metal connecting piece 3, Gui glue-lines 4, LED chip 2 is connected with both positive and negative polarity metal connecting piece 3; Gui glue-line 4 is located at LED chip 2 tops, it is characterized in that: described LED chip 2 is spliced to form a whole chip block of series connection by several little chip 21 built-in metal silks 211.
Fig. 2 is that the chip of little chip 21 is connected side-looking enlarged drawing with chip, LED chip is exactly by several little chip 21 built-in metal silks 211, to be spliced to form a whole chip block of series connection like this, realize the high light efficiency LED lamp pearl of high voltage low current, realize the use electric current that reduces lamp pearl in the situation of high light efficiency, in structure, save the connecting welding of gold thread, form whole chip block with being merged together, in manufacturing process and need not consider die bond position, manufacture craft has been simplified in realization, enhances productivity.
The positive pole of described little chip 21 and negative pole are 90 degree angles and are arranged in chip dual-side, are convenient to so little chip 21 chips and are connected with the arrangement of chip, form integral blocks.
The most suitable quantity of a number of the little chip 21 in described LED chip 2 is 8, shows it is 8 little arrangements of chips modes in accompanying drawing 1.
The utility model is in actual production, and LED chip 2 is like this as the structure of same whole chip block, and convenient detection, chooses defective products, prevents from flowing into quality, service efficiency and the practicality that next operation improves product.
The utility model is simple in structure, practical, improves quality, usability and the validity of product.
