Abstract

The utility model discloses an uniform light mixing color temperature adjustable type chip carrier. The uniform light mixing color temperature adjustable type chip carrier comprises a COB substrate, an LED chip, a gold wire, fluorescent powder, and transparent silica gel. Two ends of the LED chip are provided with a chip electrode respectively, and bonded onto the COB substrate through elargol in a die bond manner. The COB substrate is provided with a substrate electrode. The chip electrodes and the substrate electrode are connected through the gold wire. The fluorescent powder is coated onto the LED chip. The transparent silica gel is used to cover the fluorescent powder. According to the utility model, the fluorescent powder of different color temperatures is coated onto different LED chips on a same COB substrate, the assembly process time in the packaging process can be reduced, the working efficiency can be improved; and at the same time, the fluorescent powder of different color temperatures is lit on a same COB substrate in a cross manner during utilization, the uniform light mixing can be realized easily, the color difference in the light color temperature adjustment process can be reduced, and the light overall effect can be improved.

Description

A kind of color-adjustable warm type of even light mixing carries central layer

Technical field

The utility model relates to chip substrate technical field, and the color-adjustable warm type that is specially a kind of even light mixing carries central layer.

Background technology

Along with people's living standard constantly improves, people are no longer satisfied with single lighting system, abundant and the innervation of light coloring is just progressively pursued by people, and the light source of different-colour can be built different luminous environment effect and photochromic, thereby gives people with different mental impressions.By a large amount of comparative study, low colour temperature, to a kind of warmth of people, comfortable, classical sensation, is relatively applicable to perceptual one side, for example chat etc.; Middle colour temperature to people be a kind of salubrious, swash sensation clear, fashion, be applicable to reading, having a dinner etc.; High color temperature is a kind of pure, pure and fresh, lucid and lively serious sensation to people's, and relatively suitableeer rational one side, for example, work, manage household affairs etc.

The LED lamp of adjustable color temperature mainly concentrates on two kinds on the market at present: a kind of is by change, to flow through the electric current of light fixture, thereby reaches the effect that regulates lamp brightness; Another kind is to utilize three kinds of primary-color LED chip portfolios of red, yellow, and green, by regulating the each group of brightness that LED chip is different, be combined into the light source of different brightness and different-colour, but in anabolic process, COB(Chip On Board, chip on board) packing forms of realizing color-temperature regulating is that COB is divided into several, is in use prone to mixed light inhomogeneous, thereby affect the colour temperature of light, and then affect the whole structure of light.

Utility model content

The technical problem that the utility model solves is to provide a kind of color-adjustable warm type of even light mixing to carry central layer, to solve the shortcoming in above-mentioned background technology.

The technical problem that the utility model solves realizes by the following technical solutions:

The color-adjustable warm type of even light mixing carries a central layer, comprises COB substrate, LED chip, gold thread, fluorescent material, transparent silica gel; Wherein, described LED chip two ends are provided with chip electrode, and pass through elargol die bond in COB substrate, on described COB substrate, be provided with electrode of substrate, described chip electrode is connected by gold thread with electrode of substrate, and described fluorescent powder coating is on LED chip, and described transparent silica gel covers on fluorescent material.

In the utility model, described LED chip is matrix structure on COB substrate.

In the utility model, on described LED chip, intersection is coated with the fluorescent material of different-colour, and transparent silica gel covers on fluorescent material and sealed, thereby realizes multiple color temperatures; The fluorescent material of different-colour is coated in different LED chip surface on same COB substrate, in use the fluorescent material of different-colour intersection is lighted on same COB substrate and is easily realized even light mixing, reduce the aberration occurring in the adjusting of light colour temperature, improve the whole structure of light.

Beneficial effect: the utility model is coated in the fluorescent material of different-colour on same COB substrate on different LED chip, is conducive to reduce the assembling procedure time in encapsulation process, increases work efficiency; In use the fluorescent material of different-colour intersection is lighted on same COB substrate and is easily realized even light mixing simultaneously, reduces the aberration occurring in the adjusting of light colour temperature, improves the whole structure of light.
