Abstract

An LED module includes a lamp frame (2) defining a first cavity therein, an LED light source (1) disposed in the lamp frame (2), a prism (3), a reflecting plate (4), a brightness enhancement plate (5) disposed above the reflecting plate (4), and a diffusing plate (6) disposed above the brightness enhancement plate (5). The LED light source (1) includes at least a white light LED and a red light LED. The prism (3) is disposed to seal the opening (21) of the first cavity and includes a light exiting surface (32) and a light incident surface (31) facing the LED light source (1). The reflecting plate (4) is disposed at a side of the prism (3) adjacent to the light exiting surface (32). The brightness enhancement plate (5) defines a sealed second cavity together with the prism (3) and the reflecting plate (4).

Description

technical field [0001] The invention belongs to the field of LEDs, in particular to a side-emitting LED module and an LED lamp. Background technique [0002] Existing LED lamps and lanterns mostly use blue light to excite white light LEDs of YAG phosphor powder in their light-emitting modules. Although this kind of LED has mature manufacturing technology, low cost and high luminous efficiency, its color rendering index is not ideal and cannot meet the needs of high-quality lighting. [0003] The existing technology uses white LEDs, red LEDs and green LEDs to be mixed and arranged according to a certain ratio, or white LEDs and red LEDs are mixed and arranged according to a certain ratio to form a light-emitting module of an LED lamp, which is applied to direct-lit lamps. Advantages It can obviously improve the color rendering index, but the disadvantage is that the thickness of the lamp is relatively thick, which is not beautiful enough, and the direct type is more likely to...
