Abstract
A high-lighting-effect light-emitting diode (LED) bulb lamp comprises a drive power supply, a lamp casing, an LED lamp plate, a radiator, a lamp body, a lamp holder and a plurality of LED chips arranged on the LED lamp plate, wherein the LED chips are evenly arranged on the LED lamp plate in a concentric outer-circle and inner-circle mode at intervals. The LED chips include white LED chips and red LED chips, an outer circle of the LED lamp plate is provided with the white LED chips, and an inner circle of the LED lamp plate is provided with the white LED chips and the red LED chips. The high-lighting-effect LED bulb lamp is provided with the LED lamp plate, the color rendering index (Ra) of the high-lighting-effect LED bulb lamp can be greatly improved so as to meet the users' using demands for high luminance and color rendering index of the LED bulb lamp under the condition that the luminance of the LED bulb lamp is less reduced.
Description
Technical field
The utility model relates to the LED lighting technical field, particularly relates to a kind of high light efficiency LED bulb lamp.
Background technology
The LED bulb lamp is the outward appearance bulb profile that adopts people to be accustomed to-spherical, and what internal light source was selected is LED chip, thereby it possesses advantages such as LED light fixture light efficiency is high, energy-saving and environmental protection, long service life.
The colour rendering index of light source (Ra) has been described the present degree of light source to the object true colors.Due to current LED bulb lamp necessary sacrificing luminance when improving colour rendering index, and brightness reduction amplitude is very large.
Improve colour rendering index so the LED bulb lamp of prior art can not meet in the situation that guarantees high brightness, can not meet user's user demand.
The utility model content
The purpose of this utility model is to avoid weak point of the prior art and high light efficiency LED bulb lamp that the high brightness that a kind of colour rendering index is high is provided.
The purpose of this utility model realizes by following technical measures:
A kind of high light efficiency LED bulb lamp, comprise: driving power, lamp housing, LED lamp plate, radiator, lamp body, lamp holder and be arranged at the some LED chips on described LED lamp plate, described LED chip becomes the form of concentric cylindrical and inner circle, even compartment of terrain to be arranged on described LED lamp plate, described LED chip comprises white LED chip and red LED chips, wherein, the cylindrical of described LED lamp plate arranges described white LED chip, and the inner circle of described LED lamp plate arranges described white LED chip and red LED chips.
Preferably, the number of above-mentioned red LED chips is 2, is arranged at respectively the two ends of described LED lamp plate inner circle.
Preferably, the number of above-mentioned white LED chip is 13, and 8 described white LED chips are set on the cylindrical of wherein said LED lamp plate, and 5 described white LED chips are set on the inner circle of described LED lamp plate.
The utility model compared with prior art has the following advantages: the LED chip of high light efficiency LED bulb lamp of the present utility model becomes the form of concentric cylindrical and inner circle, even compartment of terrain to be arranged on described LED lamp plate, the cylindrical of described LED lamp plate arranges described white LED chip, and the inner circle of described LED lamp plate arranges described white LED chip and red LED chips.Mode by high light efficiency LED bulb lamp of the present utility model arranges the LED lamp plate, can be in the situation that the brightness of less reduction LED bulb lamp improves the colour rendering index (Ra) of high light efficiency LED bulb lamp widely, to meet the user demand of user to high brightness and the high color rendering index (CRI) of high light efficiency LED bulb lamp.
The accompanying drawing explanation
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in accompanying drawing does not form any restriction of the present utility model.
Fig. 1 is the decomposition texture schematic diagram of high light efficiency LED bulb lamp of the present utility model;
Fig. 2 is the structural representation of the LED lamp plate of high light efficiency LED bulb lamp of the present utility model.
The specific embodiment
With accompanying drawing, the utility model is further described with the following Examples:
A kind of high light efficiency bulb lamp, as depicted in figs. 1 and 2, comprise: driving power 40, lamp housing 10, LED lamp plate 20, radiator 30, lamp body 50, lamp holder 60 and be arranged at the some LED chips 21 on described LED lamp plate 20, the form of 21 one-tenth concentric cylindricals of described LED chip and inner circle, evenly compartment of terrain is arranged on described LED lamp plate 20, described LED chip 21 comprises white LED chip 22 and red LED chips 23, wherein, the cylindrical of described LED lamp plate 20 arranges described white LED chip 22, the inner circle of described LED lamp plate 20 arranges described white LED chip 22 and red LED chips 23.
The form of 21 one-tenth concentric cylindricals of the LED chip of high light efficiency bulb lamp of the present utility model and inner circle, even compartment of terrain are arranged on described LED lamp plate 20, the cylindrical of described LED lamp plate 20 arranges described white LED chip 22, and the inner circle of described LED lamp plate 20 arranges described white LED chip 22 and red LED chips 23.Mode by high light efficiency bulb lamp of the present utility model arranges LED lamp plate 20, can be in the situation that the brightness of less reduction LED bulb lamp improves the colour rendering index (Ra) of high light efficiency bulb lamp widely, to meet the user demand of user to high brightness and the high color rendering index (CRI) of high light efficiency bulb lamp.
As a kind of preferred embodiment of high light efficiency bulb lamp of the present utility model, as shown in Figure 2, the number of red LED chips 23 can be set to 2, is arranged at respectively the two ends of described LED lamp plate 20 inner circles.The number of white LED chip 22 can be set to 13, and 8 described white LED chips 22 are set on the cylindrical of wherein said LED lamp plate 20, and 5 described white LED chips 22 are set on the inner circle of described LED lamp plate 20.Through distant place instrument test, if the LED lamp plate of LED bulb lamp is set by the prior art mode, all LED that are about on the LED lamp plate are set to White LED, and when light efficiency reaches 120LM/W, colour rendering index is 60.And by the mode of high light efficiency bulb lamp of the present utility model, LED lamp plate 20 is set, through distant place instrument test, when light efficiency reaches 120LM/w, colour rendering index is 80.As can be seen here, mode by high light efficiency bulb lamp of the present utility model arranges LED lamp plate 20, can be in the situation that the brightness of assurance LED bulb lamp improves the colour rendering index (Ra) of high light efficiency bulb lamp widely, to meet the user demand of user to high brightness and the high color rendering index (CRI) of high light efficiency bulb lamp.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not to the restriction of the utility model protection domain; although with reference to preferred embodiment, the utility model has been done to explain; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical solution of the utility model, and not break away from essence and the scope of technical solutions of the utility model.
