Abstract
The utility model relates to a warm white LED light source with high-brightness and high color rendering index. The warm white LED light source comprises a lamp body, an adjustable LED driving power supply and a lamp panel which are arranged in the lamp body, a plurality of red light LEDs and white light LEDs which are fixed on the lamp panel, and a lamp shade arranged at the upper part of the lamp body. The warm white LED light source has the advantages that the brightness and the color temperature of the LEDs can be adjusted by adjusting the adjustable power supply, so that excellent warm white light effect with high-brightness and high color rendering index can be obtained, and the lamp can be more suitable for illumination.
Description
Technical field
The utility model relates to field of semiconductor illumination, more particularly, relates to a kind of warm white LED light source of high brightness high color rendering index (CRI).
Background technology
Semiconductor lighting have environmental protection, overlong service life, energy-efficient, anti-adverse environment, simple in structure, volume is little, in light weight, response is fast, operating voltage is low and the good characteristics of security, therefore be described as after incandescent lamp, fluorescent lamp and electricity-saving lamp the 4th generation lighting electric light source, or be called the 21 century green light source.
At present, be used to the led light source lamp plate that throws light on the market, mainly form by single white light LEDs of planting.Normal lighting then mainly is to use the warm white source, and in the prior art, the brightness of warm white LED is all very low, and light efficiency is not high, generally can only reach below the 60Lm/W, and colour rendering index can only reach about 70, can not satisfy the requirement of normal lighting.
In addition, led light source is because be subjected to the restriction of volume, and power can not be done too greatly, and therefore the brightness of single lamp does not reach requirement, can't replace traditional Halogen lamp LED or electricity-saving lamp.The light source that existing monochromatic LED lamp is made can not be adjusted colour temperature and brightness, and a kind of brightness and colour temperature can only be arranged.
The utility model content
The technical problems to be solved in the utility model is, at the above-mentioned defective of prior art, provides a kind of warm white led light source of high brightness high color rendering index (CRI).
The technical scheme that its technical problem that solves the utility model adopts is: the warm white LED light source that designs a kind of high brightness high color rendering index (CRI), comprise lamp body, also comprise the LED driving power, the lamp plate that are arranged in the lamp body in the described warm white LED light source, be fixed on several red-light LEDs and white light LEDs on the lamp plate, and the lampshade that is arranged on lamp body top.
As further improvement in the technical proposal, the warm white LED light source of above-described a kind of high brightness high color rendering index (CRI), described LED driving power is a regulated power supply, by regulating brightness and the colour temperature that described warm white LED lamp is regulated in quantity that red-light LED and white light LEDs light and brightness.
As further improvement in the technical proposal, the warm white LED light source of above-described a kind of high brightness high color rendering index (CRI), described red-light LED and white light LEDs are high brightness, are evenly distributed on the lamp plate.By different distribution design, can obtain different lighting effects.
As further improvement in the technical proposal, the warm white LED light source of above-described a kind of high brightness high color rendering index (CRI), described lampshade are translucent, can make light that the LED lamp sends evenly, soft.
As further improvement in the technical proposal, the warm white LED light source of above-described a kind of high brightness high color rendering index (CRI), described ruddiness and white LED lamp are direct insertion LED, great power LED or adopting surface mounted LED.
Implement the warm white LED light source of a kind of high brightness high color rendering index (CRI) of the present utility model, have following beneficial effect:
1, can obtain good warm white effect, make light fixture be more suitable for illumination, effectively energy savings.
2, the utility model structural design is brief, can effectively reduce the fraction defective of product, guarantees consistency of product, enhances productivity greatly, reduces the cost of product.
3, use translucent lampshade, make the bright dipping of LED lamp softer, not dazzling, and can not see the LED spot light.
4, can regulate the brightness and the colour temperature of warm white LED light source by regulated power supply, obtain different lighting effects, satisfy the requirement to light of varying environment.
