Problems solved by technology

[0003] However, this single-lens LED has obvious defects when used in some special environments, such as in the headlights of automobiles, trains and other vehicles, in road lighting such as street lights and tunnel lights, indoor lighting and photographic lighting. It is often desired to distribute light more evenly, which requires the use of various lenses and reflectors to achieve

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 Shown is the structure diagram of the LED lamp bead of the present invention. It includes an LED light-emitting chip 2, which is placed in the center of the lens 1 and the housing 4 through the bracket 3, and connected to the pins.

[0019] Such as figure 2 Shown is the top view of the LED lamp bead of the present invention. The lens 1 is a double-headed semi-lens with a half-hump shape, and is integrally formed with the housing 4, and is elliptical when viewed from above. The oval lamp bead is a 0.06W low-power LED lamp bead, which changes the traditional 5mm round head LED lamp bead from the original single circular lens to two double-headed semi-lens lamp beads.

[0020] Such as image 3 Shown is a side view of the LED lamp bead of the present invention. The LED lamp beads can be any LED lamp beads of 0.06 wat...

Abstract

The invention relates to a low-power LED lamp bead which comprises an LED luminous chip. The LED luminous chip is located at the center of a lens and the internal center of a shell through a support and connected with pins. The lens is a double-end semi-permeable mirror, is in a semi-hump shape, and is integrated with the shell. The lens is oval when overlooked. The photometric characteristic of the LED lamp bead can be corrected and improved, a road surface can be more even, it is guaranteed that the illumination can not be substantially attenuated, the requirement for a photometric curve required by the national roadway lighting standard can be met, and the effective utilization rate of light can be increased. The lighting efficiency of an LED street lamp and a tunnel lamp can be improved, and the electricity consumption of the LED street lamp and the tunnel lamp can be reduced.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a low-power LED lamp bead. Background technique [0002] In the process of packaging low-power LEDs, a circular lens of transparent resin is installed outside the chip, so that the light-emitting angle can be matched with lenses of different angles according to the requirements of use. [0003] However, this single-lens LED has obvious defects when used in some special environments, such as in the headlights of automobiles, trains and other vehicles, in road lighting such as street lights and tunnel lights, indoor lighting and photographic lighting. Often it is desirable to have a more even distribution of light, which is accomplished using various lenses and reflectors. [0004] For lamps using hundreds or thousands of low-power LED lamp beads, due to the small space and large quantity, it is impossible to do it due to cost and operability considerations.
