Problems solved by technology
The light spot directly emitted by the LED light source is generally circular, and the center of the light spot is relatively bright, and it will gradually become darker around it, resulting in glare. Therefore, it is necessary to design the light distribution of the LED light source to meet the requirements of use. Most of the existing All of them use reflectors and lenses to cooperate with the light distribution design to achieve the output of rectangular light spots with "bat wing" light distribution curve distribution and anti-glare requirements, such as Chinese patents CN204153652U and CN104062694A, but this light distribution method is due to At the same time, the reflective device and lens are used, which makes the product structure complex, with many consumables and high cost

Embodiment Construction
[0026] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.
[0027] In order to illustrate the present invention better, we first establish X, Y-axis Cartesian coordinate system, claim X-axis direction as horizontal, Y-axis direction as vertical, and figure 2 The B-B direction is on the X-axis, and the A-A direction is on the Y-axis.
[0028] Such as Figure 1-6 As shown, an anti-glare lighting module includes a radiator 100, a light source board 200, a reflector 300 and a face shield 400. The radiator 100 is arranged on the back of the light source board 200, and the reflector 300 is arranged on the front of the light source board 200, so that the light source The light is reflected out, and the mask 400 covers the light source board 200 and the reflector 300 and is fixed with the heat sink 100 to form a lighting module as a whole. It is fixed on the aluminum substrate by means of welding or bonding. The m...

The invention relates to the field of lighting lamps, and discloses an anti-dazzle lighting module which comprises a radiator, a light source plate, a reflector and a face mask. The radiator is arranged at the back of the light source plate, the reflector is arranged at the front of the light source plate, so that light of a light source is reflected, and the face mask covers the light source plate and the reflector and is fixed to the radiator to form a module entirety. An inclined reflection surface on the reflector covers the light source, the light source cannot be seen from the front, a light-emitting area is enlarged, surface brightness is reduced, and better anti-dazzle effects are achieved. The anti-dazzle lighting module can output rectangular light spots with 'batwing' light distribution curves and can be applied to lighting of special occasions such as roads and transformer substations. The anti-dazzle lighting module does not need to be matched with a lens to prevent dazzle and output the rectangular light spots with the 'batwing' light distribution curves and is simple in structure, less in consumable and low in cost.
Description
technical field [0001] The invention relates to the field of lighting fixtures, in particular to an anti-glare lighting module capable of outputting rectangular light spots with a "batwing" light distribution curve distribution. Background technique [0002] In the field of lighting, LED light source has many advantages such as small size, low energy consumption, high luminous efficiency, no mercury, no ultraviolet rays, long service life, etc. It is a new type of green light source product, which must be the future development trend and is widely used in various fields. [0003] In some special fields of lighting, such as road lighting, substation equipment maintenance lighting, etc., it is required that the LED light source output a rectangular spot with a "bat wing" light distribution curve distribution to improve light utilization and reduce unnecessary waste. glare effect. The light spot directly emitted by the LED light source is generally circular, and the center of...
