Problems solved by technology
The display screen made of in-line solid-state light source has good airtightness, high brightness, and strong environmental adaptability, but its viewing angle is small, color uniformity is strong, black and white contrast is low, and the production process is complicated.
The main reason for the above defects is that during the production process of the display screen, the pins of the in-line solid-state light source must be inserted into the printed circuit board and then wave soldered. The production efficiency of this process is low, and the consistency of the insertion direction is difficult to control.
The display screen made of surface-mounted solid-state light source has the advantages of large viewing angle, good light distribution and color mixing effect, delicate image, and medium brightness. It is suitable for large-scale automatic production, but its failure rate and attenuation speed are high. The adaptability of the environment is poor, and at the same time, it cannot ensure that the light energy carried is transmitted to the eyes of the viewer to the greatest extent.

The invention discloses a novel surface-mounted light-emitting device, and the light-emitting device comprises a light-emitting chip which comprises a fixed bonding surface and a light-emitting surface, wherein the fixed bonding surface and the light-emitting surface are disposed oppositely; a metal support which comprises a fixed light-emitting chip, a first plane attached to the fixed bonding face and a second plane serving as a pasting piece face, wherein the light-emitting face of the light-emitting chip and the second plane are arranged in a non-parallel mode. By means of the novel surface-mounted light-emitting device, the carried light energy can be transmitted to the eyes of a viewer to the maximum extent.
Description
technical field [0001] The present application relates to the field of light source technology, in particular to a novel surface-mount light-emitting device. Background technique [0002] Solid-state light sources include semiconductor light-emitting devices, such as light-emitting diodes, which can emit light under the action of driving electric power. They are green, pollution-free, clean and energy-saving light sources, and have wide applications in outdoor lighting, stage lighting and projector light sources. [0003] The existing solid-state light source has two structures: in-line type and surface mount type. The display screen made of in-line solid-state light source has good airtightness, high brightness, and strong environmental adaptability, but its viewing angle is small, color uniformity is strong, black and white contrast is low, and the production process is complicated. The main reason for the above defects is that the pins of the in-line solid-state light so...
