Problems solved by technology

[0003] However, the light guide sheet in CN202546362 may reflect part of the light emitted by the LED lamp panel back to the LED lamp panel, thus reducing the efficiency of the lamp
In particular, if the optical function of the light guide is strong, the associated back reflection increases
This reduces lamp efficiency, which increases lamp cost
In addition, the light absorbed by the LED light panel also increases the temperature of the LED light panel, which shortens the life of the lamp

Abstract

The present invention relates lamp (10), comprising: a carrier (12); a series (28a) of solid state light sources (30) mounted on the carrier (12); and a cover member (32a) covering the series (28a) of solid state light sources (30), wherein openings (40) are provided in the carrier (12) between the solid state light sources (30) of said series (28a) of solid state light sources (30), such that light emitted from the series (28a) of solid state light sources (30) and reflected back towards the carrier (12) by the cover member (32a) is allowed to pass the carrier (12) through the openings (40). The present invention also relates to a lighting fixture comprising at least one such lamp (10).

Description

technical field [0001] The present invention relates to a lamp, eg a flat replacement bulb comprising light emitting diodes. The invention also relates to a lighting device comprising at least one such lamp. Background technique [0002] CN202546362 discloses an LED (Light Emitting Diode) lamp, which includes a lamp holder arranged at the bottom of the bulb; an LED circuit board arranged in the lamp holder; a vertically fixed LED lamp board, wherein the LED lamp board is connected to the The LED circuit board in the lamp holder is electrically connected; and the light guide sheet overlapped on the light-emitting surface of the LED lamp board. [0003] However, the light guide sheet in CN202546362 may reflect part of the light emitted by the LED lamp panel back to the LED lamp panel, thus reducing the efficiency of the lamp. In particular, if the optical function of the light guiding sheet is high, the associated back reflection increases. This reduces the efficiency of th...
