Description

A high-transmittance and high-efficiency LED lamp

technical field

The utility model relates to the technical field of LED lighting equipment, in particular to an LED lamp with high light transmission and high light efficiency.

Background technique

LED lamps have been widely used in various lighting places, among which the use of LED lamp tubes is the most common. LED lamp tubes replace traditional fluorescent tube lighting sources and have made great contributions to lighting energy saving. Referring to FIG. 1 , the existing LED light tube includes a light tube lampshade 101 made of PC or acrylic, an LED lamp bead 102 , a lamp bead light bar substrate 103 , and a light bar frame 104 . This kind of LED lamp tube is limited by the tube diameter and structural problems, which has three adverse effects: first, the number of groups of LED lamp beads 102 and lamp bead light bar substrate 103 that can be accommodated inside is limited. Two groups, that is, LED double-tube lamps; second, the maximum distance from the inner surface of the lamp shade 1 to the LED lamp bead 102 is relatively small, generally less than 20mm. If the lamp shade 101 is made of PC or acrylic material with high light transmittance , The glare problem of the lamp beads will not be solved, which will seriously affect the visual comfort of the lighting; the third is that the light emitted by the LED lamp tube will be more than 180 degrees divergent irradiation. In order to solve the glare problem of the LED lamp bead 102, the LED lamp shade 101 of the LED lamp tube has to use acrylic or PC material with low light transmittance to make the light-shielding part of the lamp tube. In this way, even if the lamp beads in the lamp tube have high luminous flux, the illuminance of one of the lighting indicators will be affected accordingly.
