The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the embodiment of the present invention discloses a lighting module, which can form a lamp by being assembled with a lamp body 600. The lighting module includes an optical member 100, a light source 200, a light distribution lens 300, and a sealing member. The lamp body 600 may be a single component or a combination of multiple components.

The optical element 100 has an input end, an optical cavity 111, and an output end, the input end is communicated with the output end through the optical cavity 111, the light source 200 is installed in the optical cavity 111 and is disposed at the input end, and the optical element 100 can provide a certain protection effect for the light source 200.

Meanwhile, the light distribution lens 300 is arranged in the optical cavity 111, and the light distribution lens 300 is arranged on the light source 200 in a covering manner, so that light emitted by the light source 200 is emitted from the light emitting end after being distributed by the optical element 100 and the light distribution lens 300 together in the working process of the illumination module, and the illumination effect of the whole illumination module can be improved; moreover, under the combined action of the light distribution lens 300 and the optical element 100, the lighting module can be prevented from generating a glare condition; in addition, by changing the structure and/or size of the light distribution lens 300, the light-emitting angle of the lighting module can be relatively smaller, and the light gathering capability is improved.

In order to ensure that the lighting module has high sealing performance, the light inlet end and the light outlet end can be provided with sealing parts, so that after the lighting module is assembled on the lamp body 600, by means of the sealing parts, a reliable sealing fit relation can be formed between the optical element 100 and the lamp body 600, and external water vapor, dust and the like are prevented from entering the optical cavity 111 to cause adverse effects on the subsequent working process of the lighting module.

Specifically, optical element 100 can adopt hard materials such as plastics or metal to make, and preferably, optical element 100 can adopt the better material of heat conductivity such as metal to make to at the course of the operation of lighting module, not only can give off the heat with the help of lamp body 600, can also derive the heat that light source 200 work produced with the help of optical element 100, reduce lighting module's bulk temperature, promote lighting module's life.

The specific shape and size of the optical element 100 can be determined according to actual requirements, for example, the optical element 100 can be a bowl-shaped structure, and by arranging the light-entering end and the light-exiting end of the optical element oppositely, the number of times of reflection of the light emitted by the light source 200 arranged at the light-entering end in the optical element 100 can be reduced as much as possible, so as to ensure that the brightness of the light generated by the light source 200 is not lost too much in the transmission process; meanwhile, the diameter of the light-emitting end can be made larger than that of the light-entering end, so as to diffuse the irradiation area of the light generated by the light source 200 under the action of the optical element 100.

The light source 200 may be a point light source or a planar light source, and may be fixedly mounted at the light incident end of the optical element 100 by means of bonding, etc., and of course, a part of the light source 200 may also extend into the optical cavity 111, so as to ensure that the illumination conditions generated by the whole lighting module are relatively balanced. A portion of the light source 200 may also extend out of the optical element 100 from the light incident end to be connected to the lamp body 600, so that the light source 200 is powered by the lamp body 600, and accordingly, the lamp body 600 may be connected to the commercial power.

More specifically, as shown in fig. 1, the Light source 200 may include an LED element 210, a circuit board 220 and a wire 230, the LED element 210 may be formed by an LED (Light Emitting Diode), wherein the LED element 210 is mounted on the circuit board 220, the circuit board 220 is connected to the wire 230, and the wire 230 and the lamp body 600 may form an electrical connection relationship, so as to emit Light when the LED element 210 is externally connected with a power source, and applying the LED to the lighting module may reduce the overall energy consumption of the lighting module, and the response speed of the LED is fast, and the LED may be used as a voice-controlled lighting device or an induction lighting device, which can be well adapted to an outdoor working mode. In addition, the heat generated by the LED in the working process is relatively less, so that the total amount of heat generated by the whole lighting module during working can be further reduced, the overall temperature of the lighting module is relatively low, and the long-time working of the lighting module is facilitated. The circuit board 220 can change the illumination mode of the LED element 210, and the like, and the circuit board 220 can be further provided with a circuit protection element to improve the safety performance of the whole lighting module, the circuit board 220 is connected with the lamp body 600 through a wire 230, and the wire 230 can be a copper enameled wire.

The specific shape of the light distribution lens 300 can be determined according to actual requirements, and as described above, in the design and production stages of the lighting module, the light distribution lens 300 with a corresponding shape can be manufactured according to the size of the light-emitting angle.

The sealing member may be made of a flexible material such as rubber, so that the sealing effect on the optical cavity 111 may be improved to some extent by elastically deforming the sealing member during the fitting with the optical element 100. The shape of the sealing member may be similar to the light incident end and the light exit end, and in the case that the structures and/or sizes of the light incident end and the light exit end are different, in order to facilitate the following description of the fitting relationship between the sealing member and the optical element 100, the sealing member may include a first sealing member 400 and a second sealing member 500, where the first sealing member 400 is fitted with the light exit end, and the second sealing member 500 is fitted with the light incident end, so as to ensure that both the light incident end and the light exit end may form a relatively reliable sealing fitting relationship with the lamp body 600.
