Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] Such as image 3 As shown, the LED light bulb with high power and large angle light distribution of the present invention includes LED lamp bead 1, LED lamp board 2, upper radiator 3, lamp body radiator 4, lamp body 6, power board 7, light transmission cover 8. Power supply molded case 9, lamp holder 10.

[0015] The upper and lower sides of the LED lamp board 2 are respectively equipped with an upper radiator 3 and a lamp body radiator 4. The circumferential surface of the upper radiator 3 shrinks inwardly from top to bottom to form an inverted conical reflective surface 5. The lamp body radiator The circumferential surface of 4 shrinks inwardly from bottom to top to form a tapered reflective surface 5, and the LED lamp beads 1 are arranged on the upper and lower outer edges of the LED lamp board 2, and are close to the upper radiator 3 and th...

Abstract

The invention relates to a high-power and large-angle light distribution LED (Light Emitting Diode) bulb, which comprises LED lamp beads, an LED lamp panel, an upper radiator and a lamp body radiator. The upper radiator and the lamp body radiator are respectively installed in the middles of the upper surface and the lower surface of the LED lamp panel. The circumferential surface of the upper radiator is inwards contracted from the top to the bottom to form an inverted-cone-shaped reflecting surface. The circumferential surface of the lamp body radiator is inwards contracted from the bottom to the top to form a cone-shaped reflecting surface. The LED lamp beads are arranged on the outer edges of the upper surface and the lower surface of the LED lamp panel and are close to the reflecting surfaces of the upper radiator and the lamp body radiator. The high-power and large-angle light distribution LED bulb has the advantages that since a unique LED lamp panel installation method is adopted, the heat dissipating area is increased; since the radiators are used as reflectors, the high-power heat dissipation and light distribution requirements are satisfied; since the scale dimension of the bulb is large, the light output angle is increased; and at the same time, the requirements on luminous flux and light distribution are satisfied and the industrial standards are met.

Description

technical field [0001] The invention relates to an LED light bulb, in particular to a high-power LED light bulb which achieves a large-angle light distribution effect through internal LED distribution and reflection of a radiator. Background technique [0002] Bubble lamps have safety standard size standards, (see IEC60630 standard) such as A60, B35, P45, etc., and the light distribution requirements of large-angle LED lamps meet the requirements of the US Energy Star ( Figure 4 ). When designing LED bulbs, it is necessary to meet both the appearance standards of safety regulations and the requirements for large-angle light distribution. At present, most LED bulb lamps use the lower part to dissipate heat, and the upper part to transmit light, see the attached figure 1 , The heat dissipation part adopts metal or heat conduction material for heat dissipation. The light-transmitting part is mostly made of glass or light-transmitting plastic and other materials as the cover...
