Abstract

The utility model discloses a high-power light-emitting diode (LED) lamp cap which comprises LED single bead arrays arranged on a support in a lamp body. The support comprises a horizontal base plate and side plates connected to two sides of the horizontal base plate and inclined upwards outwards at the same angle. The horizontal base plate and the side plates on two sides of the horizontal base plate correspond to a forward-direction light-emitting face and two side-direction light-emitting faces of the lamp body respectively, power of the LED single bead arrays on the two side plates is identical, included angles between the side plates on two sides of the horizontal base plate and the horizontal base plate are larger than 0 degree and smaller than 20 degrees, the power of the LED single bead array on the horizontal base plate is larger than or equal to 80% of the total power, and power of the LED single bead array on each side plate is smaller than or equal to 10% of the total power. The light-emitting face of the lamp body is divided into the forward-direction light-emitting face and the two side-direction light-emitting faces, so that the LED single bead array support is correspondingly set as the horizontal base plate and the side plates on two sides of the horizontal base plate, and expansion of an illumination range is achieved by power distribution and changes of illumination angles under the conditions that the total power and loss illuminating brightness of the lamp cap are not changed.

Description

High power LED bulb holder

(1) technical field:

The utility model relates to light fixture, is specially a kind of high power LED bulb holder.

(2) background technology:

The LED(light emitting diode) be a kind of can be the solid-state semiconductor device of visible light with electric energy conversion, having the characteristics such as long, the high and low radiation of light efficiency of life-span and low-power consumption, utilize the LED(light emitting diode) light fixture made replacing traditional ordinary incandescent lamp, fluorescent lamp and spiral energy-saving lamp gradually.

Described LED(light emitting diode) core of light fixture is the combination, particularly high-powered LED lamp of the single pearl of LED, is the single pearl array of the LED that is integrated on the exiting surface flat board.

The tradition high-powered LED lamp, the single pearl arranged in arrays of LED is on the exiting surface base plate of bracket of lamp body, universal utilization (as the illumination of the occasions such as large-scale meeting-place, gymnasium) along with high-powered LED lamp, for enlarging illumination zone, Adopts measure is for enlarging simply the power of LED lamp, means are for increasing the single pearl quantity of LED and enlarging the single pearl array area of LED, but the increase along with the single pearl quantity of LED, for solving heat dissipation problem, need larger heat abstractor and the more heterogeneous pass components and parts of configuration area of dissipation, directly cause the high-powered LED lamp cost to increase substantially.

(3) utility model content:

For the deficiency of conventional art, the purpose of this utility model is to have proposed the high power LED bulb holder that a kind of change in location by the single pearl array of LED improves illumination zone.

Can realize the high power LED bulb holder of above-mentioned purpose, be included in the single pearl array of the LED that arranges on the support in lamp body, difference is that described support comprises horizonal base plate and is connected that horizonal base plate both sides connect and the side plate of the equal angular that outwards is inclined upwardly, described horizonal base plate and both sides side plate correspond respectively to forward exiting surface and the two side direction exiting surfaces of lamp body, and the single pearl array power of the LED on described biside plate is identical.

For taking into account illumination zone and brightness of illumination, the inclination angle span of described side plate for 0 °＜20 °.

Requiring for the main lighting that guarantees lamp body is the brightness of forward exiting surface, conventional power setting with described horizontal base onboard led list pearl array is more than or equal to 80% of general power, is to be less than or equal to 10% of general power with the power setting of each side onboard led list pearl array.

The beneficial effects of the utility model:

The utility model high power LED bulb holder is divided into forward and two side direction exiting surfaces with the exiting surface of lamp body, thereby the corresponding support that carries the single pearl array of LED is set to the side plate of horizonal base plate and both sides, the variation of logical overpowering distribution and light angle is not in the situation that change the lamp holder general power and lose the expansion that brightness of illumination is realized illumination zone.

(4) description of drawings:

Fig. 1 is the structural representation of a kind of embodiment of the utility model.

Fig. 2 is the upward view of Fig. 1 embodiment.

Figure number sign: 1, lamp body; 2, support; 3, the single pearl array of LED; 4, horizonal base plate; 5, side plate.

(5) specific embodiment:

Below in conjunction with accompanying drawing, the technical solution of the utility model is described further: the utility model high power LED bulb holder mainly is made of lamp body 1 and the support 2 that is installed in lamp body 1, and described support 2 is the installation carrier of the single pearl array 3 of LED, as shown in Figure 1 and Figure 2.

The shape of described support 2 is as " ship " type, the centre that is support 2 is horizonal base plate 4, described horizonal base plate 4 both sides are the side plate 5 of connected and the equal angular that outwards is inclined upwardly, the angle of inclination of each side plate 5 angle of horizonal base plate 4 (namely with) is being selected in less than the scope of 20 ° greater than 0 °, the single pearl array 3 of described LED is respectively at distributing on horizonal base plate 4 and each side plate 5, described horizonal base plate 4 and both sides side plate 5 correspond respectively to forward exiting surface and the both sides side direction exiting surface of lamp body 1, as shown in Figure 1 and Figure 2.

Press equal-wattage on biside plate 5 and distribute the single pearl array 3 of LED, and on each side plate 5, the power division of the single pearl array 3 of LED equals or is not more than 10% of lamp holder general power, thereby the power that guarantees the single pearl array 3 of LED on horizonal base plate 4 equals or is not less than 80% of lamp holder general power, guarantees that with this main body brightness of lamp body 1 is the brightness of forward exiting surface.
