The invention discloses an LED plant growth lamp adopting COB packaging. The LED plant growth lamp comprises a lamp body outer shell and an LED lamp board made of a metal-based printed circuit board, a drive assembly is installed on the LED lamp board, and the lower side of the lamp body outer shell is opened; the lower edge of the lamp body outer shell extends inwards to be provided with an inwards-extending part, and the edge of the LED lamp board is fixed to the inwards-extending part; the lower side surface of the LED lamp board is provided with a plurality of arc-shaped condensing concave parts which are vertically and horizontally arranged in order, and a lamp set is arranged in each condensing concave part; the top of each lamp set is connected with a driving assembly, and each lamp set comprises a COB integrated chip, LED lamp beads and a condensing lens which are sequentially connected from top to bottom; the LED lamp beads are colorful light sources, and the COB integrated chips are inlaid and packaged on the LED lamp board on the whole through mucilage glue; and bonding wires of the driving assemblies and the COB chips as well as the driving assemblies and the LED lamp board are packaged on the LED lamp board through the mucilage glue. The LED plant growth lamp adopting a COB packaging technology is good in heat dissipation effect, the colorful light sources are uniformly adopted, and the light color consistency is good.
Description
technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to an LED plant growth lamp. Background technique [0002] LED plant growth lamp, also known as plant lamp, is a special lamp that uses light instead of sunlight to provide a suitable light environment for the growth and development of plants based on the principle of sunlight. It is widely used in plant cultivation, greenhouse lighting, Agricultural production fields such as plant factories are used to make up for the light source needed due to the lack of sunlight. The light emitted by it has a good regulatory effect on photosynthesis, growth and development, morphogenesis and material metabolism of plants. The existing LED plant growth lamps have poor heat dissipation effect, and the temperature of the light source is too high, which may easily cause excessive light decay or direct death of the light source during use, and the service life is short; and the light color ...
