Abstract
The utility model discloses a lamp panel of an LED (Light-Emitting Diode) light source reflector lamp, which comprises a circuit board and a plurality of LED lamp beads arranged on the circuit board. The LED lamp beads are annularly and uniformly distributed on a plurality of circles with different diameters; and the diameter difference of the two adjacent uniformly-distributed circles is equal. A lighting area of the LED lamp panel can be fully distributed on the overall circuit board, even under a condition that the arrangement of the LED lamp beads is in defective tightness by annularly and uniformly distributing the LED lamp beads on the LED lamp panel; and moreover, the LED lamp panel realizes uniform lighting effect.
Description
Technical field
The utility model belongs to lighting technical field, and concrete is a kind of led light source reflectoscope lamp plate.
Background technology
Existing conventional incandescent bulb, compact fluorescent lamp have shortcomings such as power consumption is big, electro-optical efficiency is low, service life is short, and the noxious material that also contains in the compact fluorescent lamp---mercury causes potential safety hazard to environment.And the LED light fixture is emerging illuminating product, its operation cost is far below other lighting apparatus, and can satisfy increasingly serious energy-saving and cost-reducing demand, therefore more and more obtain paying attention to, the LED light fixture has energy-saving and environmental protection, radiationless advantage as the light emitting source of a new generation.
The illuminator of LED light fixture all is the LED lamp plate that is arranged in the lampshade generally, and LED lamp pearl is installed on the LED lamp plate, and in order to make the LED lamp luminous more even continuous, it is very tight that existing scheme is often arranged LED lamp pearl.But, because LED lamp pearl self has certain volume, the effect of this scheme is limited, and, the density of arranging that increases LED lamp pearl also can cause LED lamp heat radiation difficulty, temperature high, and then influences the service life of LED lamp, in addition, the quantity that increases LED lamp pearl also can increase the power of LED lamp, does not reach energy conservation and environment protection.
The utility model content
The technical problems to be solved in the utility model provides a kind of led light source reflectoscope lamp plate, and it is not only simple in structure, and need not increase the quantity of LED lamp pearl, just can make the LED lamp luminous more even continuous.
In order to solve the problems of the technologies described above, the utility model proposes a kind of led light source reflectoscope lamp plate, comprise circuit board and be installed in several LED lamp pearls on this circuit board that described LED lamp pearl annular is distributed on the circle that some diameters do not wait, and the difference of adjacent two uniform diameter of a circles equates.
By LED lamp pearl annular is arranged on the LED lamp plate in uniform way, even arrange that on LED lamp pearl the light-emitting zone of LED lamp plate also can be covered with the entire circuit plate under the situation of defective tightness, and luminous also even.
Further, described board edge is provided with the uniform recess of some annulars, can make things convenient for the LED lamp plate to be installed on the lampshade by recess is set, and it is more firm that the LED lamp plate is installed.
Further, described LED lamp pearl is an adopting surface mounted LED lamp pearl, and a plurality of described LED lamp pearls are connected in series.
In a word, led light source reflectoscope lamp plate of the present utility model is not only simple in structure, and by just LED lamp pearl annular being distributed on the circuit board, can make the light-emitting zone of LED lamp plate be covered with the entire circuit plate, and it is luminous even, in addition, led light source reflectoscope lamp plate of the present utility model also has firm beneficial effect easier for installation.

The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to utility model.
As shown in Figure 1, be the structural representation of the utility model led light source reflectoscope lamp plate embodiment, the lamp plate of present embodiment comprises circuit board 5c and is installed in several LED lamp pearl 5a on this circuit board 5c.As shown in the figure, LED lamp pearl 5a annular is distributed on the circle that some diameters do not wait, and the difference D of adjacent two uniform diameter of a circles equates that LED lamp pearl 5a is an adopting surface mounted LED lamp pearl, and a plurality of LED lamp pearl 5a are connected in series.By just LED lamp pearl annular being distributed on the circuit board, can make the light-emitting zone of LED lamp plate be covered with the entire circuit plate, and luminous even.
As shown in Figure 2, the circuit board 5c edge of present embodiment is provided with the uniform recess 5b of some annulars, upper lamp shade 2 is provided with the projection 2a that is complementary with recess 5b, and during installation, recess 5b aligns with projection 2a, the LED lamp plate is placed as projection 2a back, suitably the rotating LED lamp plate makes between circuit board 5c and the projection 2a to be connected together, in addition, it is fastening or adopt adhesive glue bonding that threaded fastener also can be set between circuit board 5c and the projection 2a, further the LED lamp plate is fixed in the upper lamp shade.
Between adjacent two projection 2a, be provided with stiffener 2b, stiffener 2b extends towards the direction of lower lamp shade 6, stiffener 2b plays a part to increase the bond area between lower lamp shade 6 and the upper lamp shade 2, stiffener 2b is set can makes bonding more firm between lower lamp shade 6 and the upper lamp shade 2, lower lamp shade 6 is bonded between this stiffener 2b and the upper lamp shade wall.
As shown in Figure 3, for using the led light source reflectoscope structural representation of present embodiment lamp plate, LED lamp plate 5 is installed in the confined space of being made up of upper lamp shade 2 and lower lamp shade 6 and is used to LED lamp pearl 5a on the LED lamp plate 5 that the constant-current source circuit of stabilized power source is provided, external power source by lamp holder 1 be input in the light fixture, lamp holder 1 by connecting line 4 link to each other with wiring board 3, wiring board 3 links to each other with LED lamp plate 5, constant-current source circuit is arranged on the wiring board 3.The constant-current source circuit of present embodiment comprises bridge rectifier and is arranged on the resistance-capacitance circuit of an input of bridge rectifier, by bridge rectifier can be dc source with the alternating current input power supplying rectification of outside, can be by resistance-capacitance circuit is set to the circuit current limliting, and make that the electric current of constant-current source circuit output is more stable, promptly the luminosity of LED lamp pearl 5a is more stable.
Above embodiment of the present utility model has been done detailed description, but the utility model is not limited to above-mentioned embodiment, in the ken that affiliated technical field those of ordinary skill is possessed, can also under the prerequisite that does not break away from the utility model aim, make various variations.
