Problems solved by technology

Although this design can make the angle larger, it will be poor in heat dissipation because its heat dissipation cross-sectional area is smaller than that of ordinary LED bulbs; in addition, making multiple aluminum light panels will increase material costs, and it will also increase the cost of materials during the assembly stage. Will increase the difficulty of assembly, thereby increasing labor costs

Embodiment 1

[0051] Embodiment 1: as Figure 1-7 As shown, a large-angle LED lamp includes a lamp base 1, a lamp body 2, a power supply housing 3 and a bulb 4. The lamp body 2 is made of an aluminum heat sink or other materials such as heat-conducting plastics and ceramics. The radiator, the interior of the lamp body 2 is a hollow structure, the lamp body 2 and the power supply housing 3 are socketed together, and the power supply housing 3 is made of heat-conducting plastic, which can effectively dissipate heat; The lamp holder 5 protrudes from the upper surface of the lamp body 2 , the longitudinal section of the bulb shell 4 is an arc larger than a semicircle, and the opening of the bulb shell 4 is installed on the periphery of the upper surface of the lamp body 2 .

[0052] The shape of the outer contour of the lamp holder 5 can be any shape in polyhedron, cylinder or frustum of a cone. In this embodiment, the shape of the outer contour of the lamp holder 5 is a frustum of a cone. For...

Embodiment 2

[0057] Embodiment 2: as Figure 9 , Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that a plurality of cup petals 14 are uniformly arranged on the upper end of the reflective cup 7 along the circumferential direction, and gaps 15 are formed between two adjacent cup petals 14 . The purpose of setting the gap is because if there is a bulb or lampshade outside the reflector of the LED lamp, on some specific bulbs or lampshades, although there is no problem with the light distribution curve of the lamp, there may be a circle of dark areas on the bulb or lampshade , set the gap 15, so that part of the light energy of the LED light source 9 outside the reflector cup 7 can pass through, and solve the possible dark areas on the bulb or lampshade.

Embodiment 3

[0058] Embodiment 3: The difference between this embodiment and Embodiment 2 is that, as Figure 11 As shown, the cup petal 14 is more slender, and the corresponding notch 15 is also more slender.

Abstract

The invention discloses a wide-angle LED lamp. The wide-angle LED lamp comprises a lamp plate and a reflection cup, wherein both the inner surface of the reflection cup and the outer surface of the reflection cup can reflect light, the lower end of the reflection cup is arranged on the lamp plate, both the part, on the inner portion of the lower end of the reflection cup, of the lamp plate and the part, on the outer portion of the lower end of the reflection cup, of the lamp plate are provided with LED light sources. Due to the fact that the both the part, on the inner portion of the lower end of the reflection cup, of the lamp plate and the part, on the outer portion of the lower end of the reflection cup, of the lamp plate are provided with the LED light sources and the lamp plate is only one, on one hand, cost is guaranteed not to be increased and machining and assembling difficulty is also reduced, and on the other hand, heat dissipation paths of the wide-angle LED lamp are enough and a heat dissipation effect cannot be influenced. Light emitted by the LED light sources inside the reflection cup is reflected and refracted through the inner surface of the reflection cup, and therefore a light emitting angle is enlarged. Light emitted by the LED light sources outside the lower end of the reflection cup is reflected and refracted through the outer surface of the reflection cup so that the light emitting angle is further enlarged, and accordingly the wide-angle LED lamp is formed.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a large-angle LED lamp. Background technique [0002] It is difficult for ordinary LED bulbs to achieve a large angle. The bulb is semicircular, so the angle basically does not exceed 200°. [0003] The existing design of large-angle LED lights is generally to set a protruding multi-faceted base on the radiator, and the LED lamp beads are attached to three or more aluminum lamp panels, and then the aluminum lamp panels are attached to the multi-faceted panels. on different side walls of the shaped base. Although this design can increase the angle, it will be poor in heat dissipation, because its heat dissipation cross-sectional area is smaller than that of ordinary LED bulbs; in addition, making multiple aluminum light panels will increase the material cost, and it will also increase the cost during the assembly stage. It will increase the difficulty of assembly, thereby i...
