Abstract

The invention discloses a full color COB light source which comprises an LED substrate, a positive electrode bonding pad, a negative electrode bonding pad, an IC integrated circuit chip, a chipset assembly, a box dam and a diffusion layer, wherein the positive electrode and negative electrode bonding pads are arranged on the LED substrate; the IC integrated circuit chip is connected with the positive electrode bonding pad; the chipset assembly is connected with the negative electrode bonding pad and the IC integrated circuit chip, and surrounded by the box dam; the diffusion layer covers the chipset; the chipset assembly comprises a red light chipset, a green light chipset and a blue light chipset which are connected with the IC integrated circuit chip through a red light chip output circuit, a green light chip output circuit and a blue light chip output circuit respectively. The full color COB light source has the advantages that red light chips, green light chips and blue light chips of an LED are combined together, and the constant current supplied to each LED chip can be controlled through the IC integrated circuit chip to ensure that the LED chips can generate light of three primary colors, including red, green and blue. Therefore, the color temperature of white light also changes, and full color visible light is formed through mixing.

Description

A kind of full-color COB light source
Technical field
The present invention relates to a kind of full-color COB light source, particularly relate to a kind of operating current size controlling three kinds of chips by IC integrated circuit (IC) chip and allow them send red, green, blue three kinds of primary lights to realize being mixed into the full-color COB light source of full color visible ray.
Background technology
It is also make white light LEDs one that full-color COB is mixed into white light, normally by each chip portfolio of LED together, sends each all primary lights, be then mixed into the visible ray of full color by electric current by them.But existing full-color COB light source does not design constant Current Control to supply the electric current of each chip of LED, the dominant wavelength skew being easy to cause LED operating current to change and causing and variable color, its poor effect and life-span shorter problem.
Summary of the invention
The present invention is the defect in order to overcome prior art, object is to provide a kind of full-color COB light source, this full-color COB light source can control the constant current of each chip supplying LED by IC integrated circuit (IC) chip, prevent because LED operating current changes the dominant wavelength skew and variable color caused, then the colour temperature of white light is made also to change, and also can control to pass through ruddiness, the size of current of green glow and blue-light LED chip, thus make that the luminous intensity of three kinds of chips is corresponding to change, realize three primary colors light mixed proportion to change thereupon, so just can produce the color of multiple conversion.
The technical solution adopted for the present invention to solve the technical problems is: a kind of full-color COB light source, comprise LED-baseplate, be located at positive terminal pad in LED-baseplate and negative terminal pad, the IC integrated circuit (IC) chip be connected with positive terminal pad, to be connected with negative terminal pad and chipset assembly that IC integrated circuit (IC) chip connects, surround chipset assembly box dam and be located at the diffusion layer covered above chipset; Described chipset assembly comprises red light chips group, green glow chipset and blue chip group, and red light chips group, green glow chipset are connected with IC integrated circuit (IC) chip with blue chip output circuit respectively by red light chips output circuit, green glow chip output circuit with blue chip group.By red, green, blue three kinds of chip portfolios of LED together, the constant current of each chip supplying LED can be controlled by IC integrated circuit (IC) chip, send red, green, blue three kinds of primary lights by electric current by them, then make the colour temperature of white light also change, be mixed into the visible ray of full color.Prevent because LED operating current changes the dominant wavelength skew and variable color caused, also can control the size of current by ruddiness, green glow and blue-light LED chip, three kinds of primary colours light intensity size of current changes, thus make that the luminous intensity of three kinds of chips is corresponding to change, the mixed light color sent is converted thereupon, realize three primary colors light mixed proportion to change thereupon, so just can produce the color of multiple conversion.
Further, each one end of described red light chips output circuit, green glow chip output circuit and blue chip output circuit and IC integrated circuit (IC) chip are for being connected in parallel, and the other end is also connected with negative terminal pad after closing.
In sum, full-color COB light source of the present invention can control the constant current of each chip supplying LED by IC integrated circuit (IC) chip, prevent because LED operating current changes the dominant wavelength skew and variable color caused, then the colour temperature of white light is made also to change, and the size of current that also can control by ruddiness, green glow and blue-light LED chip, thus make that the luminous intensity of three kinds of chips is corresponding to change, realize three primary colors light mixed proportion and change thereupon, so just can produce the color of multiple conversion.The white light that this full-color COB light source is mixed into has good color developing, wider reference color temperature, and material used and LED chip also can conveniently obtain.
