The glare reduction is an important performance indicator of a luminaire.

Referring to fig. 2, the inventors thought that the first light-transmitting globe 300 is obliquely installed to the light outlet 121 of the case 100 in order to reduce glare. However, the first light-transmitting lamp cover 300 is inclined, so that the anti-dazzle effect is poor, and the first light-transmitting lamp cover 300 is not installed in the light outlet 121 in parallel, so that the surface of the housing 100 is uneven, dust is easy to accumulate, and the daily maintenance of the LED strip lamp 20 is not facilitated.

Referring to fig. 3 and 4, the present utility model provides an LED bar lamp 20, which includes a housing 100, an LED strip 200, a first light-transmitting lamp shade 300 and a second light-transmitting lamp shade 400.

The housing 100 has an inner cavity 110, the housing 100 has a light exit plane 120, and the light exit plane 120 has a light exit 121 communicating with the inner cavity 110.

In the present utility model, the light emitting surface 201 refers to a plane perpendicular to the optical axis of the LED strip 200. The optical axis is a virtual axis. Generally, the direction of the highest illumination intensity among the light emitted from the LED strip 200 is the optical axis direction.

Optionally, the LED strip 200 includes a circuit board and LED light sources. The LED light source can be separately and electrically mounted on the circuit board or formed on the circuit board through exposure and development. In general, the surface of the circuit board on which the LED light source is mounted indicates the direction of the light emitting plane. For example, when the LED light source is an LED chip, the LED chip is mounted on the circuit board, the surface of the LED chip far from the circuit board is the light emitting surface 201, and the surface of the LED chip close to the circuit board is the light emitting surface 201 when the LED chip is flip-chip mounted on the circuit board. For another example, the light emitting surface of the LED light source is non-planar, and if the LED light source is an LED diode and the light emitted by the LED strip 200 is symmetrically distributed about the optical axis, the plane perpendicular to the optical axis is the light emitting surface 201.

It is understood that in other embodiments, the LED light strip 200 may not include a circuit board.

In one embodiment, referring to fig. 3, the included angle between the light emitting plane 120 and the light emitting surface 201 is 15 ° to 75 °, so that the light emitting plane 120 is not parallel to the light emitting surface 201, and the light emitted from the light emitting surface 201 does not direct the light emitting opening 121 and enters the human eye.

Specifically, referring to fig. 3, the light emitting plane 120 is horizontally disposed, the normal line of the light emitting plane 120 is a vertical line, the light emitting surface 201 is obliquely disposed, and an included angle a formed by the normal line of the light emitting surface 201 and the vertical line is an included angle between the light emitting plane 120 and the light emitting surface 201.

The setting of mounting plane 111 is favorable to the location installation of LED lamp area 200, and makes the light emitting area 201 of LED lamp area 200 parallel with mounting plane 111, because mounting plane 111 and light-emitting plane 120 all are located on casing 100, can carry out nonparallel design in casing 100, need not to calibrate the adjustment when the assembly for the light emitting area 201 of LED lamp area 200 of installing on mounting plane 111 is naturally assembled nonparallel with light-emitting plane 120.

Optionally, the included angle between the mounting plane 111 and the light exit plane 120 is 15 ° to 75 °.

Thus, the LED light strip 200 is located between the first mounting piece 310 and the second mounting piece 320, and the LED light strip 200 is disposed opposite to the first light-transmitting piece 330, so that the LED light strip 200 is covered by the first light-transmitting lampshade 300.

Specifically, the first support surface 112 and the second support surface 113 are disposed at opposite edges of the mounting plane 111, so that the first light-transmitting globe 300 naturally covers the LED strip 200 when the first light-transmitting globe 300 is mounted to the inner cavity 110.

Specifically, the first light-transmitting sheet 330 is a soft light sheet, for example, a semitransparent light-transmitting sheet, so that light emitted by the LED light strip 200 can be scattered, the formation of high-brightness light spots is weakened, the uniformity of the brightness inside the inner cavity 110 is enhanced, and the direct irradiation of light to human eyes is avoided, so that discomfort to the human eyes is caused.

Specifically, the first light-transmitting lampshade 300 is integrally formed, that is, the first mounting sheet 310, the second mounting sheet 320 and the first light-transmitting sheet 330 are integrally formed, and the materials are the same, so that light can be transmitted. It is understood that in other embodiments, the first mounting sheet 310, the second mounting sheet 320, and the first light transmitting sheet 330 may be joined together by bonding, welding, or the like. The materials of the first mounting sheet 310, the second mounting sheet 320, and the first light transmitting sheet 330 may be different.

Correspondingly, the area of the light outlet 121, which is not covered by the first supporting surface 112, is a non-antiglare area C, and the user can see the first light-transmitting lampshade 300 from the area, so that more light can be irradiated.

Optionally, the concave arc wall 115 is coated with a reflective material, so that the light emitted from the LED strip 200 can be reflected to the light outlet 121 through the first light-transmitting lampshade 300, which avoids light loss and is beneficial to light uniformity. It will be appreciated that in other embodiments, the concave arc wall 115 may not be coated with a reflective material, and the light may be reflected by the self-material properties of the housing 100, e.g., the housing 100 may be metallic.
