Abstract

The utility model discloses an RGB LED structure, comprising a base, a bracket and a plurality of RGB chips, wherein the RGB chips are installed on the base and comprise R color chips, G color chips and B color chips with the quantity ratio being 1:2:1; the base is a metal silver column; and the bracket is made of ceramic material. Compared with the prior art, the RGB LED structure has the advantages that as the quantity ratio of green light chips is increased, the problem of insufficient luminosity of the green light can be effectively improved; additionally, the base takes the whole silver column structure, thereby effectively improving the heat conductivity of the base.

Description

A kind of RGB LED structure

[technical field]

The utility model relates to lighting field, relates in particular to a kind of RGB LED (Red Green B1ue LED, rgb led) structure.

[background technology]

In the culture life that people are become increasingly abundant, the diversity of light of stage has been brought fine visual enjoyment to people.And as some RGB LED structures of stage lighting, especially powerful RGB LED structure is because the diversity of its color, distinctiveness, and the characteristics of control lamp able to programme aspect are widely used on decorative lighting and the demonstration stage.For example some large-scale concerts, bar, hotel, places such as building bias light.

In the prior art, powerful RGB LED structure generally includes RGB wafer, line layer and the pedestal that can send three kinds of colors of red, green, blue.When using high-power RGB LED structure, can realize color effects arbitrarily by three kinds of colors of hybrid RGB wafer.But the photometric scales that needs RGB when joining white balance is R: G: G=3 substantially: 6: 1, yet, the wafer brightness of the green glow in the present RGB LED structure is on the low side, so finished product white balance effect is relatively poor, and when RGB LED lighted simultaneously, the copper pedestal heat-sinking capability that fixed wafer is used was not enough, therefore, existing unsatisfactory with the solution of white light by the synthetic illumination of RGB LED, and, badly influence the operate as normal of RGB LED structure because radiating effect is poor.

In view of above drawback, be necessary to provide a kind of new RGB LED structure to overcome above-mentioned defective in fact.

[utility model content]

Main purpose of the present utility model is to provide a kind of new RGB LED structure, and it can not only solve the problem of white balance, also has good heat-sinking capability.

For achieving the above object, the utility model adopts following technical scheme: a kind of RGB LED structure, it comprises pedestal, support and is installed on some RGB wafers on the pedestal, described RGB wafer comprises R look wafer, G look wafer and B look wafer, wherein, the R look wafer of described RGB wafer, the ratio of G look wafer and B look number of wafers is 1: 2: 1, and pedestal is the argent post, and support is that ceramic material is made.

Compared to prior art, the utlity model has following advantage: RGB LED structure of the present utility model, owing to increased the shared ratio of green wafer quantity, therefore can effectively improve the problem of green glow luminosity deficiency, pedestal is whole silver-colored rod structure in addition, effectively improves the thermal conductivity of pedestal.

Fig. 2 is the schematic rear view of a kind of RGB LED of the utility model structure.

[specific embodiment]

Please refer to shown in Fig. 1,2, be the basic structure of the utility model preferred embodiment.A kind of RGB LED of the utility model structure, it comprises pedestal 10, support 20 and is installed on some RGB wafers on the pedestal.

Pedestal 10 roughly is the cubic bodily form, and it is the argent rod structure.Centre position in the pedestal 10 is being arranged four RGB wafers in length and breadth.

The RGB wafer can be divided into R look wafer 31, G look wafer 32 and B look wafer 33, and after the wiring pad that is installed on every kind of RGB wafer on the pedestal 10 was connected power supply, above-mentioned three kinds of RGB wafers can send redness, blueness and green light respectively.Please continue with reference to figure 1 described, the first wiring pad (401,402) be respectively the positive and negative wiring pad of R look wafer 31, the second wiring pad (501,502), the 4th wiring pad (601,602) be respectively the positive and negative wiring pad of two G look wafers 32, the 3rd wiring pad (701,702) is respectively the positive and negative wiring pad of B look wafer 33.Please continue with reference to shown in Figure 2, the periphery of pedestal 10 is provided with support 20, and described support 20 employing ageing resistaces ceramic material are preferably made, and can effectively improve luminous intensity distribution and the heat dissipation problem of LED.

During use, in RGB LED structure of the present utility model, owing to increased green wafer quantity, therefore can effectively improve the problem of green glow luminosity deficiency, pedestal 10 is whole silver-colored rod structure in addition, effectively improves the thermal conductivity of pedestal.

A kind of RGB LED of the utility model structure, be not restricted to described in specification and the embodiment, for those skilled in the art, can easily realize additional advantage and modification, therefore under the situation of the spirit and scope of the universal that does not deviate from claim and equivalency range and limited, the examples shown that the utility model is not limited to specific details, representational equipment and illustrates here and describe.
